Komputer jinjing atau Laptop atau notebook

Komputer jinjing (populer dalam bahasa Inggris: laptop, notebook, atau powerbook) adalah komputer bergerak yang berukuran relatif kecil dan ringan, beratnya berkisar dari 1-6 kg, tergantung ukuran, bahan, dan spesifikasi laptop tersebut.

Sumber daya komputer jinjing berasal dari baterai atau adaptor A/C yang dapat digunakan untuk mengisi ulang baterai dan menyalakan laptop itu sendiri. Baterai laptop pada umumnya dapat bertahan sekitar 1 hingga 6 jam sebelum akhirnya habis, tergantung dari cara pemakaian, spesifikasi, dan ukuran baterai.

Sebagai komputer pribadi, laptop memiliki fungsi yang sama dengan komputer destop (desktop computers) pada umumnya. Komponen yang terdapat di dalamnya sama persis dengan komponen pada destop, hanya saja ukurannya diperkecil, dijadikan lebih ringan, lebih tidak panas, dan lebih hemat daya. Komputer jinjing kebanyakan menggunakan layar LCD (Liquid Crystal Display) berukuran 10 inci hingga 17 inci tergantung dari ukuran laptop itu sendiri. Selain itu, papan ketik yang terdapat pada laptop juga kadang-kadang dilengkapi dengan papan sentuh yang berfungsi sebagai "pengganti" tetikus. Papan ketik dan tetikus tambahan dapat dipasang melalui soket USB maupun PS/2 jika tersedia.

Berbeda dengan komputer destop, komputer jinjing memiliki komponen pendukung yang didesain secara khusus untuk mengakomodasi sifat komputer jinjing yang portabel. Sifat utama yang dimiliki oleh komponen penyusun laptop adalah ukuran yang kecil, hemat konsumsi energi, dan efisien. Komputer jinjing biasanya berharga lebih mahal, tergantung dari merek dan spesifikasi komponen penyusunnya, walaupun demikian harga komputer jinjing pun semakin mendekati destop seiring dengan semakin tingginya tingkat permintaan konsumen.

Tips Penting: Jangan Sering Memangku Laptop

Walau namanya “laptop” yang berati “sesuatu yang diletakkan di atas pangkuan”, ternyata laptop tidak disarankan untuk dipangku. Justru memangku laptop menyebabkan kecelakaan fatal. Mengapa bisa begitu? Berikut beberapa kiat memilih dan menggunakan laptop. Siapa yang tak ingin punya komputer jinjing alias laptop. Di era serba terkomputerisasi sekarang ini, pastinya nyaris setiap orang ingin punya laptop. namun dalam memiliki atau membeli laptop tidak bisa sembarangan saja. Ada beberapa tips yang harus diperhatikan jika ingin aman dan nyaman.

Tips Membeli Laptop
Laptop jika dilihat dari definisinya adalah “sesuatu” yang diletakkan di atas(top) pangkuan (lap). Tetapi jangan terlalu sering meletakkan laptop dipangkuan, karena banyak kasus pengguna Laptop yang mengalami kecelakaan karena memangku laptop. Kasus yang sempat menyeruak adalah bagian vital yang melepuh terluka karena terpapar panas yang berlebihan dari laptop terus menerus. Tidak tahu apa yang sedang dilakukan dengan laptop itu, apakah main game yang seru banget atau memang kerjanya serius banget sampai-sampai tidak berasa kalau perangkatnya melepuh. Dalam kenyataannya, laptop lebih sering diletakkan di atas meja daripada di pangkuan.

Laptop VS PC
Jika Anda pengguna PC yang haus performa seperti pengguna aplikasi desain grafis, sering mengkonversi film dan maniak game yang haus performa, kelihatannya pilihan terbaik untuk Anda adalah PC dengan memori tinggi dan kartu grafis teranyar. Saat ini laptop grafis yang paling canggihpun masih kalah cepat dibandingkan dengan PC rakitan, selain harganya juga sangat tinggi.
Sangat tidak disarankan Anda untuk menukar PC desain grafis atau ajang pertempuran Counterstrike dan Warcraft Anda dengan laptop. Salah satu alternatif yang dapat Anda lakukan jika Anda pengguna PC adalah mengganti CRT (Cathode Ray Tube) monitor dengan LCD (Liquid Crytal Display) monitor yang lebih hemat listrik dan lebih nyaman bagi mata, tetapi pada beberapa aplikas kecepatan tampilan LCD monitor masih kalah dibandingkan dengan CRT.
Jika Anda pengguna komputer yang sedang-sedang saja dan menggunakan komputer untuk kegiatan mengetik skripsi, mengerjakan laporan keuangan, coding , mendengarkan musik, main game yang tidak haus resource dan main internet, ada pertimbangan menarik untuk Anda. Jika Anda membeli komputer dengan layar CRT 15” konvensional yang bisa dipertanggungjawabkan. Untuk menghemat listrik dan nyaman dimata Anda bisa mempertimbangkan untuk mengganti layar LCD Anda perlu menambahkan selisih US $ 80 (Rp. 720.000,-) dari monitor CRT. Jadi total biaya Rp. 3.8 juta Anda bisa mendapatkan PC yang “lumayan” hemat energi karena monitor LCD mengkonsumsi listrik jauh lebih rendah dari monitor CRT dan nyaman dimata.
Ada tips menarik yang dilakukan penulis ketika membeli monitor LCD, toko komputer menawarkan LCD baru dengan dead pixel dengan diskon 20 % dari harga yang tidak cacat. Garansi dan lainnya 100 % sama. Kalau cacat cuma satu titik saja, tidak masalah bagi penulis. Penulis langsung menyambar kesempatan ini dan sampai hari ini monitor 15 “ tersebut bertahan di meja komputer penulis tanpa masalah apapun. Tiap hari komputer tersebut digunakan rata-rata 5 jam untuk main game dan kegiatan lainnya.

Jika Anda memiliki dana sekitar RP. 5 juta, ada baiknya Anda pertimbangkan untuk membeli Laptop daripada PC. Betul, dengan 5 jutaan Anda sudah bisa mendapatkan laptop merek bagus dan bergaransi seperti Toshiba, HP ,Compaq, Acer dengan performa lebih dari cukup untuk kegiatan “normal”, mengetik, internet, dengar lagu / MP3, nonton DVD. Kelemahan laptop ini adalah harganya yang lebih mahal dan sangat sulit di upgrade dibandingkan PC, tetapi keuntungannya juga tidak kalah banyak :
Laptop lebih ringkas dan mudah dibawa-bawa karena bisa dimasukkan ke dalam tas.

Laptop sudah datang dalam satu paket hardware yang terintegrasi dan seluruh bagian laptop digaransi oleh satu vendor saja. Dibandingkan PC Anda tidak perlu pusing memilih komponen atau merakit, dimana kelebihan PC rakitan bisa fleksibel memilih spesifikasi prosesor, VGA (Video Graphics Array) card, memory, harddisk, casing dst pada sisi lain menjadi kelemahannya karena umumnya setiap komponen disediakan oleh beberapa vendor / merek yang berbeda sehingga jika terjadi klaim garansi, Anda harus berhubungan dengan banyak vendor berbeda untuk setiap komponen PC rakitan.
Konsumsi daya lebih rendah. Laptop menghabiskan daya listrik rata-rata 45 Watt, bandingkan dengan PC dengan CRT monitor yang menghabiskan daya rata-rata 240 watt.

Laptop dilengkapi dengan baterai sehingga memungkinkan Anda bekerja menggunakan baterai laptop dan tidak harus menggunakan listrik (rata-rata baterai laptop dapat digunakan 1 – 2 jam tanpa dicolokkan ke listrik untuk penggunaan normal). Selain itu, baterai laptop juga berfungsi sebagai UPS (Uninterruptible Power Supply), sehingga ketika Anda sedang bekerja dan terjadi mati lampu, baterai laptop langsung menggantikan tenaga listrik dan mencegah komputer Anda mati dan mengamankan data Anda. Jika menggunakan PC, Anda harus membeli UPS yang harganya cukup mahal.

Pertimbangan lain adalah performanya relatif tidak kalah dengan PC dan tidak ada pengaruh signifikan untuk kegiatan komputer yang normal (lihat definisi normal di atas) non game grafis yang berat atau graphic designer. Dari sisi kecepatan, sebenarnya prosesor dengan kecepatan 1 Ghz sudah cukup untuk kegiatan komputer yang mendasar, ibarat kalau makan sudah memenuhi persyaratan 4 sehat 5 sempurna. Kalau Anda memiliki komputer dengan kecepatan lebih tinggi malah terbuang untuk aplikasi lain yang kurang bermanfaat seperti walpaper hi res yang keren, screen saver, animasi, program-program add on, animasi / html wallpaper dan tampilan lainnya yang bukan merupakan kebutuhan mendasar komputer dan hanya untuk menyamanan dan kenikmatan saja. Hal ini terjadi karena tuntutan industri TI yang selalu memberikan speed lebih tinggi dan dengan harga lebih murah.

Laptop Ringan
Jika Anda membeli laptop sebagai teman Anda bepergian, dalam artian laptop tersebut sering dibawa-bawa seperti untuk presentasi, pekerjaan keluar kota atau travelling, ada baiknya Anda mencari laptop yang ringan.Salah satu faktor utama yang menentukan bobot laptop adalah ukuran layar LCD. Jadi secara logika, laptop dengan ukuran layar 14“ tidak mungkin lebih ringan dari laptop dengan layar 12 “ karena bobot layar LCD 14 “ yang lebih berat. LCD monitor merupakan komponen utama dalam laptop dan produsen di dunia ini dapat dihitung dengan sebelah jari Anda dan produsen laptop sangat jarang yang memiliki pabrik LCD sendiri dan mayoritas membeli dari pabrikan LCD sehingga bobot layarnya tidak berbeda jauh.
Laptop kecil

Laptop Kecil
Jika LCD membatasi bobot laptop, apa yang membatasi miniaturisasi laptop ? Jawabannya adalah:jempol Anda. Sebagai gambaran dari industri selular, secara teknologi sebenarnya manufaktur mampu mengecilkan ponsel dari ukuran yang sekarang. Buktinya dari beberapa tahun lalu saja handphone sudah kecil dan sampai hari ini ukurannya tidak lebih kecil lagi. Yang jadi masalah adalah ukuran jempol manusia yang tidak bisa dikecilkan dan karena handphone digunakan oleh manusia, maka harus menyesuaikan dengan ukuran jempol manusia. Hal serupa juga terjadi dengan laptop, yang menjadi kendala dalam mengecilkan laptop adalah ukuran keyboard yang tidak bisa dikecilkan karena harus mudah dan nyaman digunakan manusia dewasa.

OS, dan Program Pendukung
Salah satu hal tambahan yang penting diperhatikan dalam memilih laptop adalah universalitas dan ketergantungan terhadap vendor yang serendah mungkin. Hindari vendor yang tidak memberikan CD instalasi OS original, karena hal ini akan mempersulit Anda jika menghadapi masalah dengan OS dan harus memformat ulang. Penulis juga mengalami harus bolak-balik ke service center dua kali hanya karena harus memperbaiki OS dan vendor tidak memberikan CD / DVD sebagai backup.

Membuat Baterai Laptop Lebih Tahan Lama

Stefanus Yugo Hindarto - Okezone

Salah satu Keunggulan Laptop dibandingkan dengan computer PC adalah mudahnya Laptop untuk dibawa kemanapun juga. Tapi keunggulan itu akan sia-sia jika baterai laptop sering 'drop'. Tak jarang pengguna laptop banyak kesal karena lemahnya baterai, dan terpaksa harus membawa baterai cadangan untuk menunjang kinerja laptopnya.

Memang idealnya Baterai laptop dapat digunakan setidaknya selama dua jam, namun ada beberapa tips yang dapat membantu anda agar kinerja baterai semakin meningkat, sehingga baterai laptop menjadi lebih tahan lama. Langkah pertama sebaiknya perhatikan tampilan di monitor laptop anda, semakin terang tampilan maka energi yang dibutuhkan akan semakin besar. Untuk mengurangi konsumsi batere sebaiknya kurangi tingkat brightness pada tampilan.

Langkah lain yang dapat dilakukan adalah menghentikan sinyal wireless atau Bluetooth jika tidak digunakan. Koneksi jaringan Wi-Fi yang terus menerus dapat menguras energi baterai.



Selain itu cara lain untuk menghemat baterai laptop antara lain dengan mensetting power management pada laptop anda. Jika anda menggunakan system operasi windows XP, anda dapat mengutak-atik agar dapat menghasilkan ? low power mode? pada ? Power option? di control panel. Pilih control panel kemudian pilih power option pada kategori performance and maintanenance. Kemudian akan tampil pilihan sebagai berikut



Hal lain yang harus diperhatikan ialah cara anda mengisi baterai laptop. Usahakan laptop dalam keadaan mati saat anda mengisi baterei. Dan jika baterai telah terisi penuh, maka secepatnya anda wajib mencopot baterai adapter agar batere tidak mengalami kelebihan beban. (srn)

One Laptop Per Child

One Laptop Per Child (satu laptop untuk setiap anak) (disingkat OLPC) atau The Children's Machine atau XO-1 atau Laptop $100 adalah sebuah program penyediaan laptop dengan harga terjangkau untuk anak-anak di seluruh dunia, khususnya anak-anak di negara berkembang, dengan harapan bahwa mereka dapat mengakses pengetahuan dan pendidikan modern.

Dikemudian hari OLPC menjadi nama dari sebuah organisasi nirlaba yang dibentuk oleh anggota MIT Media Lab. Organisasi ini bertugas mendesain , membuat dan mendistribusikan laptop yang dimaksud. Program ini diprakarsai oleh Nicholas Negroponte.

Laptopnya sendiri akan berupa komputer mini yang membutuhkan tenaga sangat minim, menggunakan flash memory menggantikan hardisk, serta menggunakan linux sebagai sistem operasinya [1].

Mobile ad-hoc networking akan digunakan untuk memungkinkan beberapa laptop dapat mengakses internet secara bersama-sama dari satu akses internet.

Laptop


An ultraportable IBM X31 with 12" screen on an IBM T43 Thin & Light laptop with a 14" screen

A laptop computer, also known as a notebook computer, is a small personal computer designed for mobile use. A laptop integrates all of the typical components of a desktop computer, including a display, a keyboard, a pointing device (a touchpad, also known as a trackpad, or a pointing stick) and a battery into a single portable unit. The rechargeable battery is charged from an AC/DC adapter and has enough capacity to power the laptop for several hours.

A laptop is usually shaped like a large notebook with thickness of 0.7-1.5 inches (1.7-4cm) and dimensions ranging from 10x8 inches (27x22cm, 13" display) to 15x11 inches (39x28cm, 17" display) and up. Modern laptops weigh 3 to 12 pounds (1.4 to 5.4 kg), and some older laptops were even heavier. Most laptops are designed in the flip form factor to protect the screen and the keyboard when closed.

Originally considered "a small niche market"[1] and perceived as suitable for "specialized field applications" such as "the military, the Internal Revenue Service, accountants and sales representatives"[1][2], battery-powered portables had just 2% worldwide market share in 1986[3]. But today, there are already more laptops than desktops in the enterprise[4] and, according to a forecast by Intel, more laptops than desktops will be sold in the general PC market as soon as 2009[5].

Contents

History

Main article: History of laptops

As the personal computer began to become feasible in the early 1970s, the idea of a portable personal computer followed; in particular, a "personal, portable information manipulator" was envisioned by Alan Kay at Xerox PARC in 1968[6] and described in his 1972 paper as the "Dynabook"[7].

The first commercially available portable computer appeared 9 years later, in 1981. The Osborne 1 weighed 23.5 pounds (10.7 kg). It had no battery, a tiny 5" CRT screen and dual 5¼" single-density floppy drives. In the same year the first laptop-sized portable computer, the Epson HX-20, was announced[8]. The Epson had a LCD screen, a rechargeable battery and a calculator-size printer in a 1.6 kg (4 pounds) enclosure.

The first notebook using the clamshell design (which is utilized today by almost all laptops) appeared in 1982: the $8150 GRiD Compass 1100 was purchased by NASA and the military among others. The Gavilan SC, released in 1983, was the first notebook that was marketed using the term "laptop".

From 1983 onwards:

  • Several new input methods were introduced: the touchpad (Gavilan SC, 1983), the pointing stick (IBM ThinkPad 700, 1992) and handwriting recognition (Linus Write-Top[9], 1987).
  • CPUs became designed specifically for laptops (Intel i386SL, 1990), targeting low power consumption, and were augmented with dynamic power management features (Intel SpeedStep and AMD PowerNow!).
  • Displays reached VGA resolution by 1988 (Compaq SLT 286) and 256-color screens by 1993 (PowerBook 165c), progressing quickly to millions of colors and high resolutions.
  • High-capacity hard drives and optical storage (CD-ROM followed by DVD) became available in laptops soon after their introduction to the desktops.

Early laptops often had proprietary and incompatible architectures, operating systems and bundled applications.

Classification

The general terms "laptop" or "notebook" can be used to refer to a number of classes of small portable computers:[10][11]

By purpose and (approximately) by screen size:

  • Desktop replacement - emphasizes performance, is less portable, 17" and larger screen;
  • Standard laptop - balances portability and features, 13-15" screen;
  • Subnotebook - emphasizes portability, has less features, 13" or smaller screen.

By features:

  • Budget - a cheap, lower-performance standard-sized laptop;
  • Tablet PC - Has a touch-screen interface, may or may not have a keyboard;
  • Netbook - A cheaper, smaller version of a subnotebook designed mainly for Internet surfing and basic office applications.

Desktop replacement


An Apple 17" MacBook Pro is often used as a desktop replacement.

A desktop replacement computer is a laptop that provides most of the capabilities of a desktop computer, with a similar level of performance. Desktop replacements are usually larger and heavier than standard laptops. They contain more powerful components and numerous ports, and have a 17" or larger display. Because of their bulk, they are not as portable as other laptops and their operation time on batteries is typically shorter.[11]

Some laptops in this class use a limited range of desktop components to provide better performance for the same price at the expense of battery life; in a few of those models, there is no battery at all, and the laptop can only be used when plugged in. These are sometimes called desknotes, a portmanteau of the words "desktop" and "notebook," though the term can also be applied to desktop replacement computers in general.[12]

The names "Media Center Laptops" and "Gaming Laptops" are also used to describe this class of notebooks.[10]

Subnotebook

Main article: Subnotebook

A subnotebook, also called an ultraportable by some vendors, is a laptop designed and marketed with an emphasis on portability (small size, low weight and long battery life) that retains the performance of a standard notebook. Subnotebooks are usually smaller and lighter than standard laptops, weighing between 0.8 and 2 kg (2 to 5 pounds)[10]; the battery life can exceed 10 hours[13] when a large battery or an additional battery pack is installed.

To achieve the size and weight reductions, ultraportables use high resolution 13" and smaller screens (down to 6.4"), have relatively few ports, employ expensive components designed for minimal size and best power efficiency, and utilize advanced materials and construction methods. Some subnotebooks achieve a further portability improvement by omitting an optical/removable media drive; in this case they may be paired with a docking station that contains the drive and optionally more ports or an additional battery.

The term "subnotebook" is usually reserved to laptops that run general-purpose desktop operating systems such as Windows, Linux or Mac OS X, rather than specialized software such as Windows CE, Palm OS or Internet Tablet OS. Other types of portable computers that are smaller than subnotebooks are handheld computers and UMPCs.

Netbook

Main article: Netbook

A netbook is a small laptop designed for portability and low price, with a performance inferior to that of a standard notebook yet adequate for surfing on the Internet and basic word processing. Netbooks use 10" and smaller screens, weigh 0.6 to 1.2 kg (1.5 to 3 pounds), and are generally powered by a CPU from one of the low-cost families with a high performance-to-power ratio such as Intel Atom, Celeron ULV, or VIA C7 processors.[14]

Netbooks use general-purpose operating systems such as Linux or Windows XP. Some models use small-capacity (4 to 40 Gb) SSD drives instead of the usual HDDs to save weight and battery power.

Parts

Laptops contain components that are similar to their desktop counterparts and perform the same functions, but are miniaturized and optimized for mobile use and efficient power consumption, although typically less powerful for the same price. Most laptops use different memory modules for their random access memory (RAM), for instance, SO-DIMM in lieu of the larger DIMMs. An external keyboard or mouse can usually be attached.

Most modern laptops feature 12 inch (30 cm) or larger active matrix displays with resolutions of 1024×768 pixels and above, and have a PC Card (formerly PCMCIA) or ExpressCard expansion bay for expansion cards, one or more USB ports, and a external monitor port (VGA or DVI). Most laptops have also an ethernet network port. Some have legacy ports such as a PS/2 keyboard/mouse port or a serial port, parallel port, and S-video or composite video port. Hard disks are physically smaller—2.5 inch (60 mm)—compared to the standard desktop 3.5 inch (90 mm) drive, and usually have lower performance and power consumption. Video and sound chips are usually integrated. This tends to limit the use of laptops for gaming and entertainment, two fields which have constantly escalating hardware demands,[15] however, higher end laptops can come with dedicated graphics processors. These mobile graphics processors tend to have less performance than their desktop counterparts, but this is because they have been optimized for lower power usage. Some subsystems, such as Wi-Fi, come in contemporary laptops on replaceable MiniPCI cards, usually accessible through a door on the bottom. Memory modules (smaller than the usual DIMMs) are often also accessible through the bottom, though some may be on the motherboard under the keyboard and thus not meant to be accessed by the user.

Processors

There is a wide range of laptop specific processors available from Intel (Pentium M, Celeron, Intel Core and Intel Core 2), AMD (Athlon, Turion 64, and Sempron) ,centreno procesor ,& also centrino 2 are also available in the market and from VIA (C3 and C7-M). Motorola and IBM developed and manufactured the chips for the former PowerPC-based Apple laptops (iBook and PowerBook). Generally, laptop processors are less powerful than their desktop counterparts, due to the need to save energy and reduce heat dissipation.

Batteries

Current models of laptops utilize lithium ion batteries with more recent models using the new lithium polymer technology. These technologies have largely replaced the older nickel metal-hydride batteries. Typical battery life for most laptops is two to five hours with light-duty use, but may drop to as little as one hour with intensive use. Batteries gradually deteriorate over time and eventually need to be replaced in one to five years, depending on the charging and discharging pattern.


Laptops typically use SODIMMs, as shown here.

This very powerful main battery should not be confused with the much smaller battery nearly all computers use to run the real-time clock and backup BIOS configuration into the CMOS memory when the computer is without power.

Virtually all laptops can be powered from an external AC converter. This device typically adds half a kilogram (1 lb) to the overall "transport weight" of the equipment.

Docking stations

Docking stations became another common laptop accessories in the early 1990s. They typically were quite large and offered 3.5" and 5.25" storage bays, one to three expansion slots (typically AT style), and a host of connectors. The mating between the laptop and docking station was typically through a large, high-speed, proprietary connector. The most common use was in a corporate computing environment where the company had standardized on a common network card and this same card was placed into the docking station. These stations were very large and quite expensive. As the need to additional storage and expansion slots became less critical because of the high integration inside the laptop itself, the emergence of the Port Replicator as a major accessory commenced. The Port Replicator was often a passive device that simply mated to the connectors on the back of the notebook and allowed the user to quickly connect his laptop so VGA, PS/2, RS-232, etc. devices were instantly attached. As higher speed ports like USB and Firewire became commonplace, the Port Replication was accomplished by a small cable connected to one of the USB 2.0 or FireWire ports on the notebooks. Wireless Port Replicators followed.

Navigation

A pointing stick or touchpad is used to control the position of the cursor on the screen. The pointing stick is usually a rubber dot that is located between the G, H and B keys on the laptop keyboard. To navigate the cursor, pressure is applied in the direction intended to move. The touchpad is touch-sensitive and the cursor can be navigated by moving the finger on the pad.

Standards

Intel, Asus, Compal, Quanta and other laptop manufacturers have created Common Building Block standard for laptop parts.

Advantages


Laptop computers are portable and can be used in many locations.

The main advantage of laptops over their larger desktop counterparts is the inherent portability. Another advantage is the laptop's ability to operate on battery power in the case of a power outage, less energy consumption and heat production.

Disadvantages

Parts standardization and compatibility issues

Current compatibility problems in the laptop trade are reflective of the early era of personal computer hardware, when there were many different manufacturers, each and every one of them having their own connectivity and mounting systems and incompatibility was the norm. While there are accepted world standards of form factors for all the peripherals and add-in PC cards used in the desktop computers, there are still no firm worldwide standards relating to today's laptops' internal form factors, such as supply of electric voltage, motherboard layouts, internal adapters used in connecting the optical drive, LCD cable, keyboard and floppy drive to the main board. Most affected by this are users uneducated in the relevant fields, especially if they attempt to connect their laptops with incompatible hardware or power adapters.

Some hard drives and memory are commodity items and are interchangeable. However, other parts such as motherboards, keyboards, and batteries are proprietary in design and are only interchangeable within a manufactures brand and/or model line.

A significant point to note is that the vast majority of laptops on the market are manufactured by a small handful of Original Design Manufacturers (ODM).[16] The ODM matters more than the Original Equipment Manufacturer (OEM). Major relationships include:

  • Quanta sell to (among others) HP/Compaq, Dell, Toshiba, Sony, Fujitsu, Acer, NEC, Gateway and Lenovo/IBM - note that Quanta is currently (as of August, 2007) the largest manufacturer of notebook computers in the world.
  • Compal sells to Toshiba, HP/Compaq, Acer, and Dell.
  • Wistron (former manufacturing & design division of Acer) sells to HP/Compaq, Dell, IBM, NEC, Acer, and Lenovo/IBM.
  • Flextronics (former Arima Computer Corporation notebook division) sells to HP/Compaq, NEC, and Dell.
  • ECS sells to IBM, Fujitsu, and Dell.
  • Asus sells to Apple (iBook), Sony, and Samsung.
  • Inventec sells to HP/Compaq, Toshiba, and BenQ.
  • Uniwill sells to Lenovo/IBM and Fujitsu.

Durability problems


Example of how laptop performance slowly declines after several years, due to dust and lint buildup on internal heat sinks. Simply blowing air into the vents is not enough to remove this buildup. Instead, laptop disassembly is required to properly clean the heatsink.

Due to their portability and tight integration, laptops are more subject to wear and physical damage than desktops. Components such as batteries, screen hinges, power jacks, and power cords are commonly subject to deterioration due to ordinary use. These components are usually expensive to replace, with a typical laptop battery costing US$130, the AC Adapter US$75.

Other parts are inexpensive, such as a power jack costing perhaps US$20, but replacement may require extensive disassembly and reassembly of layers of internal components. Other inexpensive but fragile parts often cannot be purchased separate from larger more expensive components. For example, the video display cable and backlight power cable that passes through the lid hinges to operate the screen will eventually break from opening and closing the lid hundreds of times over many years, and usually these tiny cables cannot be purchased separate from an entire US$400 LCD panel.

A liquid spill onto the keyboard, which is rather a minor mishap with a desktop system can damage costly components such as the motherboard or LCD panel. Dropping a laptop can damage the LCD screen if not break apart its body. The repair costs of a failed motherboard or LCD panel may exceed the purchase value of the laptop.

Laptops must also rely on extremely compact cooling systems involving a fan and heat sink that eventually fails due to filling with airborne dust and debris. Most laptops do not have any sort of removable dust collection filter over the air intake for these cooling systems, resulting in a system that gradually runs hotter and louder as the years pass. Eventually the laptop cooling is so choked with dust that it starts to overheat just from minor operational load. This dust is usually deeply buried inside where casual cleaning and vacuuming cannot remove it, and instead complete disassembly is needed to clean the laptop.

Rugged laptops

Some manufacturers have mitigated some of these problems by selling "ruggedized" laptops. These often have a rubber sheeting under the keyboard keys and special drain that safely routes all of the water out through a hole in the bottom of the case.

Additionally, the bodies of these laptops are typically made of a stiffer magnesium alloy instead of plastic, since it is the flexing of the circuit boards and fragile mechanical devices that causes the most damage. Hard drives are often mounted in soft shock-absorbing silicone mounts to greatly increase their chances of surviving a waist-high fall.

When a laptop hits the floor, the free-floating hard drive heads can slap against the spinning platter, scratching it and cause an irrepairable head crash that renders the hard drive unusable. Recently hard drives have been constructed which can move the read heads completely off the spinning platters, known as unloading. With the use of an accelerometer, the hardware can detect the sudden fall and park the heads off-platter before the laptop hits the ground. (See Sudden Motion Sensor.)

Upgradeability

Laptops' upgradeability is severely limited, both for technical and economic reasons. As of 2006, there is no industry-wide standard form factor for laptops. Each major laptop vendor pursues its own proprietary design and construction, with the result that laptops are difficult to upgrade and exhibit high repair costs. With few exceptions, laptop components can rarely be swapped between laptops of competing manufacturers, or even between laptops from the different product-lines of the same manufacturer. Standard feature peripherals (such as audio, video, USB, 1394, WiFi, Bluetooth) are generally integrated on the main PCB (motherboard), and thus upgrades often require using external ports, card slots, or wireless peripherals. Other components, such as RAM modules, hard drives, and batteries are typically user-upgradeable.

Many laptops have removable CPUs, although support for other CPUs is restricted to the specific models supported by the laptop motherboard. The socketed CPUs are perhaps for the manufacturer's convenience, rather than the end-user, as few manufacturers try new CPUs in last year's laptop model with an eye toward selling upgrades rather than new laptops. In many other laptops, the CPU is soldered and non-replaceable.[17]

Many laptops also include an internal MiniPCI slot, often occupied by a Wi-Fi or Bluetooth card, but as with the CPU, the internal slot is often restricted in the range of cards that can be installed. The widespread adoption of USB mitigates I/O connectivity to a great degree, although the user must carry the USB peripheral as a separate item.

NVidia and ATI have proposed a standardized interface for laptop GPU upgrades (such as an MXM), but again, choices are limited compared to the desktop PCIe/AGP after-market.

In January 2007, Asus announced XG Station external video card for laptops. XG Station is connected to the laptops using USB-2 and Express card interface.

In February 2007, a new standard for external PCI Express cables and connectors was announced. Future laptops can be expanded using external PCI Express backplane and chassis.

Performance

For a given price range (and manufacturing base), laptop computational power has traditionally trailed that of desktops. This is partly due to most laptops sharing RAM between the program memory and the graphics adapter. By virtue of their usage goals, laptops prioritize energy efficiency and compactness over absolute performance. Desktop computers and their modular components are built to fit much bigger standard enclosures, along with the expectation of AC line power. As such, energy efficiency and portability for desktops are secondary design goals compared to absolute performance.

For typical home (personal use) applications, where the computer spends the majority of its time sitting idle for the next user input, laptops of the thin-client type or larger are generally fast enough to achieve the required performance. 3D gaming, multimedia (video) encoding and playback, and analysis-packages (database, math, engineering, financial, etc.) are areas where desktops still offer the casual user a compelling advantage.

As computer hardware miniaturization develops, laptops are beginning to close the performance gap with desktops. Intel's Core 2 line of processors is efficient enough to be used in portable computers, and many manufacturers such as Apple Inc., Lenovo and Dell are building Core 2 based laptops. Also, many high end laptop computers feature mobility versions of graphics cards, eliminating the performance losses associated with integrated graphics, while maintaining long battery life.

Health problems

A study by State University of New York researchers says heat generated from laptops can significantly elevate the temperature of the scrotum, potentially putting sperm count at risk. The small study, which included little more than two dozen men ages 13 to 35, found that the sitting position required to balance a laptop can raise scrotum temperature by as much as 2.1 °C (3.8 °F). Heat from the laptop itself can raise the temperature by another 0.7 °C (1.4 °F), bringing the potential total increase to 2.8 °C (5.2 °F). However, further research is needed to determine whether this directly affects sterility in men.[18] A common practical solution to this problem is to place the laptop on a table or desk.

Heat from using laptop on lap can also cause skin discoloration on the thighs.[19]

Because of their small keyboard and trackpad pointing devices, the use of laptops can cause RSI, and for this reason laptops have docks that are used with ergonomic keyboards to prevent injury. The integrated screen often causes users to hunch over for a better view, which can cause neck or spinal injuries. Some health standards require that ergonomic keyboards be used in workplaces.

Security

Laptops are generally prized targets of theft, and theft of laptops can lead to more serious problems such as identity theft from stolen credit card numbers.[20] Most laptops have a Kensington security slot to chain the computer to a desk with a third party security cable. In addition to this, modern operating systems and software may have disk encryption functionality that renders the data on the laptop's hard drive unreadable without a key.

Related devices

A laptop can use the same software as a desktop machine but is small enough to support mobile computing and operate on battery power. Devices that are similar to a laptop include:

Transportable, also called portable computers
Computers which can easily be moved from place to place, but cannot be used while in transit, usually because they require AC power. The most famous example is the Osborne 1. A transportable, like a laptop, can run desktop software; but it does not support mobile computing.
Tablets
Computers shaped like slates or (paper) notebooks featuring touchscreen interfaces and a stylus, plus handwriting recognition software. As of 2007, the most common subcategory is the Tablet PC, which is essentially a laptop with a touchscreen. Some tablets have no keyboard, while others called "convertibles" have a screen that can be rotated 180 degrees and folded on top of the keyboard. Tablets may have limited functionality and not be best suited for applications requiring a physical keyboard for typing, but are otherwise capable of carrying out most tasks that an ordinary laptop would be able to perform.
Internet tablets
Internet appliances in tablet form. An internet tablet supports mobile computing. Internet tablets usually use Linux and they are able to run some applications, but they cannot replace a general purpose computer. Internet tablets typically feature an MP3 and video player, web browser, chat application, and picture viewer.
Personal digital assistants (PDAs)
Small computers, usually pocket-sized, usually with limited functionality. A PDA supports mobile computing, but almost never runs any desktop software.
Handheld computers
A high-end PDA or small tablet.
Smart phone
A hand held or PDA with an integrated cellphone.

Boundaries that separate these categories are blurry at times. For example, the OQO UPC is a PDA-sized tablet PC; the Apple eMate had the clamshell form factor of a laptop, but ran PDA software. The HP Omnibook line of laptops included some devices small enough to be called handheld computers. The hardware of the Nokia 770 internet tablet is essentially the same as that of a PDA such as the Zaurus 6000; the only reason it's not called a PDA is that it doesn't have PIM software. On the other hand, both the 770 and the Zaurus can run some desktop Linux software, usually with modifications.

Jakarta (also DKI Jakarta), is the capital and largest city of Indonesia. It also has a greater population than any other city in Southeast Asia. It was formerly known as Sunda Kelapa (397-1527), Jayakarta (1527-1619), Batavia (1619-1942), and Djakarta (1942-1972). Located on the northwest coast of Java, it has an area of 661.52 square kilometres (255.41 sq mi) and a population of 8,489,910[1]. Jakarta is the country's economic, culture and political center. Jakarta currently is the twelfth largest city in the world. Its metropolitan area, Jabodetabek, contains more than 23 million people, and is part of an even larger Jakarta-Bandung megalopolis.[citation needed]

Jakarta is served by the Soekarno-Hatta International Airport and Tanjung Priok harbour. Since 2004, Jakarta, while under the governance of Sutiyoso, has built a new bus system known as "TransJakarta" or "Busway", and is now planning to expand the number of routes. The city had hoped to establish its newest transportation system, the Jakarta Monorail, in 2007, but the project was abandoned by the developer, PT Jakarta Monorail, in March 2008. Jakarta is the location of the Jakarta Stock Exchange, the Bank of Indonesia, and the National Monument, or Tugu Monas.

Geography


Jakarta skyline and Mount Gede

Jakarta is located on the northwestern coast of Java Island, at the mouth of the Ciliwung River on Jakarta Bay, which is an inlet of the Java Sea. The northern part of Jakarta is constituted on a plain land, approximately eight meters above the sea level. This contributes to the frequent flooding. The southern parts of the city are hilly. There are about 13 rivers flowing through Jakarta, mostly flowing from the hilly southern parts of the city northwards towards the Java Sea. The most important river is the Ciliwung river, which divides the city into the western and eastern principality. The city border is the province of West Java on its east side and the province of Banten on its west side.

The thousand islands, which is a part of the administrative region of Jakarta, is located in the Jakarta Bay. These 105 islands are located 45 kilometres (28 mi) on the north part of the city.

Climate

Jakarta has a hot and humid equatorial/tropical climate (Af) according to the Köppen climate classification system. Located in the western-part of Indonesia, Jakarta's wet season rainfall peak is January with average monthly rainfall of 350 millimetres (14 in), and its dry season low point is August with a monthly average of 60 millimetres (2.4 in).[2] The city is humid throughout the year with daily temperature range of 25° to 38°C (77°-100°F).[3]

History

For more details on this topic, see History of Jakarta.

The former Stadhuis of Batavia, the seat of Governor General of VOC. The building now serves as Jakarta Historical Museum, Jakarta Old Town area.

Dutch Batavia in the 17th Century, built in what is now North Jakarta

The old name of Jakarta was Sunda Kelapa. The earliest record mentioning this area as a capital city can be traced to the Indianized kingdom of Tarumanagara as early as the fourth century. In AD 39, King Purnawarman established Sunda Pura as a new capital city for the kingdom, located at the northern coast of Java.[4] Purnawarman left seven memorial stones with inscriptions bearing his name spread across the area, including the present-day Banten and West Java provinces. The Tugu Inscription is considered the oldest of all of them.[5]

After the power of Tarumanagara declined, all of its many territories, including Sunda Pura, became part of the Kingdom of Sunda. The harbour area were renamed Sunda Kelapa as written in a Hindu monk's lontar manuscripts, which are now located at the Bodleian Library of Oxford University in England, and travel records by Prince Bujangga Manik.[6] By the 14th century, Sunda Kelapa became a major trading port for the kingdom. The first European fleet, four Portuguese ships from Malacca, arrived in 1513 when the Portuguese were looking for a route for spices, especially black pepper.[7]

The Kingdom of Sunda made a peace agreement with Portugal by allowing the Portuguese to build a port in 1522 in order to defend against the rising power of the Sultanate of Demak from central Java.[8] In 1527, Fatahillah, a Sumatran Malay warrior from Demak attacked Kingdom of Sunda and succeeded in conquering the harbour on June 22, 1527, after which Sunda Kelapa was renamed Jayakarta.[8]

Through the relationship with Prince Jayawikarta from the Sultanate of Banten, Dutch ships arrived in Jayakarta in 1596. In 1602, the British East India Company's first voyage, commanded by Sir James Lancaster, arrived in Aceh and sailed on to Banten where they were allowed to build a trading post. This site became the center of British trade in Indonesia until 1682.[9]

Apparently, Jayawikarta also made a trading connection with the English merchants, rivals of the Dutch, by allowing them to build houses directly across from the Dutch buildings in 1615.[10] When relations between Prince Jayawikarta and the Dutch later deteriorated, Jayawikarta's soldiers attacked the Dutch fortress. But even with the help of fifteen British ships, Prince Jayakarta's army wasn't able to defeat the Dutch, in part owing to the timely arrival of Jan Pieterszoon Coen (J.P. Coen). The Dutch burned the English fort, and forced the English retreat on their ships. With this victory, Dutch power in the area was consolidated. In 1619 they renamed the city "Batavia."


Batavia c.1870

Within Batavia's walls, wealthy Dutch built tall houses and pestilential canals. Commercial opportunities attracted Indonesian and especially Chinese immigrants, the increasing numbers creating burdens on the city. Tensions grew as the colonial government tried to restrict Chinese migration through deportations. On 9 October 1740, 5,000 Chinese were massacred and the following year, Chinese inhabitants were moved to Glodok outside the city walls.[11] The city began to move further south as epidemics in 1835 and 1870 encouraged more people to move far south of the port. The Koningsplein, now Merdeka Square, was completed in 1818, and Kebayoran Baru was the last Dutch-built residential area.[11]

The city was renamed "Jakarta" by the Japanese during their World War II occupation of Indonesia. Following World War II, Indonesian Republicans withdrew from allied-occupied Jakarta during their fight for Indonesian independence and established their capital in Yogyakarta. In 1950, once independence was secured, Jakarta was once again made the national capital.[11] Indonesia's founding president, Sukarno, envisaged Jakarta as a great international city. He instigated large government-funded projects undertaken with openly nationalistic and modernist architecture.[12][13] Projects in Jakarta included a clover-leaf highway, a major boulevard (Jalan Sudirman), monuments such as The National Monument, major hotels, and a new parliament building.

In 1966, Jakarta was declared a "special capital city district" (daerah khusus ibukota), thus gaining a status approximately equivalent to that of a state or province.[14] Lieutenant General Ali Sadikin served as Governor from this time to 1977; he rehabilitated roads and bridges, encouraged the arts, built several hospitals, and a large number of new schools. He also cleared out slum dwellers for new development projects—some for the benefit of the Suharto family[15][16]—and tried to eliminate rickshaws and ban street vendors. He began control of migration to the city in order to stem the overcrowding and poverty.[17] Land redistribution, structural adjustment,[citation needed] and foreign investment contributed to a real estate boom which changed the face of the city.[18] The boom ended with the 1997/98 East Asian Economic crisis putting Jakarta at the center of violence, protest, and political maneuvering. Long-time president, Suharto, began to lose his grip on power. Tensions reached a peak in the Jakarta riots of May 1998, when four students were shot dead at Trisakti University by security forces; four days of riots and violence ensued resulting in the loss of an estimated 1,200 lives and 6,000 buildings damaged or destroyed.[19] Suharto resigned as president, and Jakarta has remained the focal point of democratic change in Indonesia.[20] A number of Jemaah Islamiah-connected bombings have occurred in the city since 2000.[11]

Administration

Officially, Jakarta is not a city, but rather a province with special status as the capital of Indonesia. It is administered much like any other Indonesian province. For example: Jakarta has a governor (instead of a mayor), and is divided into several sub-regions with their own administrative systems. Jakarta, as a province, is divided into five cities (kota), formerly municipalities, each headed by a mayor, and one regency (kabupaten) headed by a regent. In August 2007, Jakarta held its first ever election to pick a governor; the election was won by Fauzi Bowo. The city's governors have previously been appointed by local parliament. The poll is part of a country-wide decentralization drive, allowing for direct local elections in several areas.[21]

Culture

As the economic and political capital of Indonesia, Jakarta attracts many foreign as well as domestic immigrants. As a result, Jakarta has a decidedly cosmopolitan flavor and a diverse culture. Many of the immigrants are from the other parts of the island of Java, bringing along a mixture of dialects of the Javanese and Sundanese languages, as well as their traditional foods and customs.

Jakarta is sometimes called "The Big Durian" by foreigners resident in the city. The durian is a tropical fruit with a distinctive odor and acquired taste. A bustling urban metropolis, Jakarta is known for its overcrowding, traffic congestion, and income disparity.

The Betawi (Orang Betawi, or "people of Batavia") is a term used to describe the descendants of the people living around Batavia and recognized as a tribe from around the 18th-19th century. The Betawi people are mostly descended from various Southeast Asian ethnic groups brought or attracted to Batavia to meet labor needs, and include people from various parts of Indonesia.[22] The language and culture of these immigrants are distinct from those of the Sundanese or Javanese. The language is more based on East Malay dialect and enriched by loan words from Javanese, Chinese, and Arab. Nowadays, the Jakarta-dialects used by people in Jakarta is loosely based on Betawi Language.

There has also been a significant Chinese community in Jakarta for many centuries. Officially, they make up 6% of the Jakarta population, though this number may be under-reported.[23]

Jakarta has several performance centers, such as the Senayan center. Traditional music is often found at high-class hotels, including wayang and gamelan performances. As the nation's largest city and capital, Jakarta has lured much national and regional talent who hope to find a greater audience and more opportunities for success.

Ironically, the Betawi arts are rarely found in Jakarta due to their infamous low-profile and most of them had moved to the border of Jakarta, ridden by the wave of immigrant. It is easier to find Java or Minang based wedding ceremonial instead of Betawi wedding in Jakarta. It is easier to find Javanese Gamelan instead of Gambang Kromong (mixture between Betawi and Chinese music) or Tanjidor (mixture between Betawi and Portuguese music) or Marawis (mixture between Betawi and Yaman music). However, some festivals such as Jalan Jaksa Festival or Kemang Festival tried to preserve the Betawi art by inviting the artist to do some performances.[24]

The concentration of wealth and political influence in the city means that it has much more noticeable foreign influence on its landscape and culture, an effect illustrated by the presence in the city of many major international fast-food chains, for example.

Transportation


Jalan Thamrin, a main road in Central Jakarta

One of the most populous cities in the world, Jakarta is strained by transportation problems."[25] In Indonesia most communal transport is provided by bemos, which are privately run minibuses.

Road transport


Jakarta traffic

Despite the presence of many wide roads, Jakarta suffers from congestion due to heavy traffic, especially in the central business district. To reduce traffic jams, some major roads in Jakarta have a 'three in one' rule during rush hours, first introduced in 1992, prohibiting fewer than three passengers per car on certain roads.

Jakarta's roads are notorious for undisciplined driver behavior; transportation laws are broken with impunity and police bribery is commonplace. The painted lines on the road are regarded as mere suggestions as vehicles often travel four or five abreast on a typical two-lane road. It is not uncommon to encounter a vehicle traveling the wrong direction in a given traffic flow. Furthermore, in recent years the number of motorcycles on the streets has been growing almost exponentially. The vast sea of small, 100-200cc motorcycles, many of which have 2-stroke motors, create much of the traffic, noise and air pollution that plague Jakarta.


Motorised bajaj

Auto rickshaws, called bajaj (pronounced badge-eye), provide local transportation in the back streets of some parts of the city. From the early 1940s to 1991 they were a common form of local transportation in the city. In 1966, an estimated 160,000 rickshaws were operating in the city; as much as fifteen percent of Jakarta's total workforce was engaged in rickshaw driving. In 1971, rickshaws were banned from major roads, and shortly thereafter the government attempted a total ban, which substantially reduced their numbers but did not eliminate them. An especially aggressive campaign to eliminate them finally succeeded in 1990 and 1991, but during the economic crisis of 1998, some returned amid less effective government attempts to control them.[26]

To reduce traffic congestion, a new TransJakarta bus system was introduced.

The TransJakarta service operates on a special bus-line called the busway. The busway network is optimized for busy city routes and is a relatively effective alternative for travel in Jakarta. Construction of the 2nd and 3rd corridor routes of the busway was completed in 2006, serving the route from Pulo Gadung to Kalideres. The busway serving the route from Blok M to Jakarta Kota has been operational since January 2004.

An outer ring road is now being constructed and is partly operational from Cilincing-Cakung-Pasar Rebo-Pondok Pinang-Daan Mogot-Cengkareng. A toll road connects Jakarta to Soekarno-Hatta International Airport in the north of Jakarta. Also connected via toll road is the port of Merak and Tangerang to the west and Bekasi, Cibitung and Karawang, Purwakarta and Bandung to the east.

Rail and Waterway

While numerous railways serve Jakarta, they are inadequate to the residents' transport needs. During peak hours, the number of passengers greatly exceeds the system's capacity. The railroads connect Jakarta to its neighboring regions: Depok and Bogor to the south, Tangerang and Serpong to the west, and Bekasi, Karawang, and Cikampek to the east. The major rail stations are Gambir, Jatinegara, Pasar Senen, Manggarai, Tanah Abang, and Jakarta Kota.


Jakarta Railway transportation system

Two lines of the Jakarta Monorail are under construction: the green line serving Semanggi-Casablanca Road-Kuningan-Semanggi and the blue line serving Kampung Melayu-Casablanca Road-Tanah Abang-Roxy. In addition, there are plans for a two-line subway (MRT) system, with a north-south line between Kota and Lebak Bulus, with connections to both monorail lines; and an east-west line, which will connect with the north-south line at the Sawah Besar station. The current project, which began in 2005, has been delayed due to a lack of funds, and the project has been abandoned by the developer PT Jakarta Monorail in March 2008. The government is now looking for new investors.

On 6 June 2007, the city administration started to introduce the Waterway, a new river boat service along the Ciliwung river.[25] The move aims to reduce the traffic snarls in Jakarta.[27]

On 30 November 2007, KRL(Commuter Train) Ciliwung Blue Line began operation.[28] It serves Jakarta's circle line, which was used in the 80s. The fare price is Rp5000,00. It serves Manggarai, Mampang, Karet, Jend. Sudirman Road, Duri, Angke, Kampung Bandan, Rajawali, Kemayoran, Pasar Senen, Gang Sentiong, Kramat, Pondok Jati, and Jatinegara. The train can carry 400 passengers.[29]

Air

Soekarno-Hatta International Airport (CGK) is the primary airport for Jakarta and Indonesia alike. It is used by both private and commercial carriers connecting Jakarta with other Indonesian cities. It is also Indonesia's main international gateway. The airport is divided into three separate terminals. Terminal 1 serves all domestic airliners except Garuda Indonesia. Terminal 2 serves all foreign carriers and Garuda Indonesia (both domestic and international routes). Terminal 3 serves for hajj pilgrimage flights and for transnational migrant laborers.[30] A second airport, Halim Perdanakusuma International Airport(HLP) serves mostly private and presidential flights.

Education

See also: List of universities in Indonesia

Jakarta is the home of many universities, the oldest of which are state-run University of Indonesia(UI)[31] and the privately-owned Universitas Nasional (UNAS)[32]. There are also many other private universities in Jakarta, such as Universitas Trisakti [33] and Universitas Tarumanagara, which are two of the few largest private universities in Jakarta. As the largest city and the capital, Jakarta houses a large number of students from various parts of Indonesia, many of whom reside in dormitories or home-stay residences. Similar to other large cities in developing Asian countries, there are many professional schools. For basic education, there are a variety of primary and secondary schools, tagged with public (national), private (national and bi-lingual national plus) and international schools. Two of the major international schools located in Jakarta are the Jakarta International School and the Gandhi Memorial International School. JIS is an IASAS school.

Sports

Since Soekarno's era, Jakarta has often been chosen as the venue for international sport events, such as being the host of Asian Games in 1962, host of Asian Cup 2007 and several times hosting the regional-scale Sea Games. Jakarta is also home of several professional soccer clubs. The most popular of them is Persija, which regularly plays its matches in the Lebak Bulus Stadium. Another premiere division team is Persitara. The champions of Galatama competition, Warna Agung and Jayakarta soccer club, also homebase in Jakarta. The biggest stadium in Jakarta is the Bung Karno Stadium with a capacity of 100,000 seats[34]. For basketball, the Kelapa Gading Sport Mall in Kelapa Gading, North Jakarta, with a capacity of 7,000 seats, is the home arena of the Indonesian national basketball team. Many international basketball matches are played in this stadium. The Senayan sports complex comprises several sport venues, which include the Bung Karno soccer stadium, Madya Stadium, Istora Senayan, a shooting range, a tennis court and a golf driving range. The Senayan complex was built in 1959 to accommodate the Asian Games in 1962. In 2011, Jakarta, together with Bandung, will once again host the Southeast Asian Games. Preparations to host the event have started since the conclusion of the 2007 Thailand Southeast Asian Games. The Indonesian Polo Association, as the governing body of polo in Indonesia, have stated its commitment to host the SEA Games polo tournament in Indonesia after polo is confirmed to be absent in the 2009 Laos Southeast Asian Games. The Indonesian Polo Team were placed last in the 2007 Southeast Asian Games.

Problems

Population in excess of infrastructure

Like many big cities in developing countries, Jakarta suffers from major urbanization problems. The population has risen sharply from 1.2 million in 1960 to 8.8 million in 2004, counting only its legal residents. The population of greater Jakarta is estimated at 23 million, making it the fourth largest urban area in the world. The rapid population growth has outgrown the government's ability to provide basic needs for its residents. As the third biggest economy in Indonesia, Jakarta has attracted a large number of visitors. The population during weekdays is almost double that of weekends, due to the influx of residents residing in other areas of Jabotabek. Because of government's inability to provide adequate transportation for its large population, Jakarta also suffers from severe traffic jams that occur almost every day. Air pollution and waste management are also severe problems. By 2025 the population of Jakarta may reach 24.9 million, not counting millions more in surrounding areas.[35]

Sanitation

Surveys show that "less than a quarter of the population is fully served by improved water sources. The rest rely on a variety of sources, including rivers, lakes and private water vendors. Some 7.2 million people are [without clean water]."[36]

Flooding

During the wet season, Jakarta suffers from flooding due to clogged sewage pipes and waterways, deforestation near rapidly urbanizing Bogor and Depok, and the fact that 40% of it is below sea level[citation needed]. Terrible floods occurred in 1996[37][38] when 5,000 hectares flooded [39] and 2007.[40] Losses from infrastructure damage and state revenue were at least 5.2 trillion rupiah (572 million US dollars) and at least 85 people were killed [41] and about 350,000 people forced from their homes.[42]. Approximately 70% to 75% of Jakarta's total area was flooded and water up to 4 meters deep in parts of city.[43] [44] [45]

The informal sector

In September 2007, a new law was brought into effect which attempted to regulate aspects of public order. It forbids the giving of money to beggars, buskers and hawkers, bans squatter settlements on river banks and highways, and prohibits spitting and smoking on public transportation. Unauthorized people cleaning car windscreens and managing traffic at busy intersections will also be penalized. Critics of the new legislation claim that such laws will be difficult to enforce and ignore the desperate poverty of many of the capital's inhabitants.
