bukittinggi

History

Fort de Kock in 1826
The city has its origins in five villages which served as the basis for a marketplace.[1]
The city was known as Fort de Kock during colonial times in reference to the Dutch outpost established here in 1825 during the Padri War. The fort was founded by Captain Bauer at the top of Jirek hill and later named after the then Lieutenant Governor-General of the Dutch East Indies, Hendrik Merkus de Kock.[2] The first road connecting the region with the west coast was built between 1833 and 1841 via the Anai Gorge, easing troop movements, cutting the costs of transportation and providing an economic stimulus for the agricultural economy.[3] In 1856 a teacher-training college (Kweekschool) was founded in the city, the first in Sumatra, as part of a policy to provide educational opportunities to the indigenous population.[4] A rail line connecting the city with Payakumbuh and Padang was constructed between 1891 and 1894.[5]
During the Japanese occupation of Indonesia in World War II, the city was the headquarters for the Japanese 25th Army, the force which occupied Sumatra. The headquarters was moved to the city in April 1943 from Singapore, and remained until the Japanese surrender in August 1945.[6]

During the Indonesian National Revolution, the city was the headquarters for the Emergency Government of the Republic of Indonesia (PDRI) from December 19, 1948 to July 13, 1949. During the second 'Police Action' Dutch forces invaded and occupied the city on December 22, 1948, having earlier bombed it in preparation. The city was surrendered to Republican officials in December 1949 after the Dutch government recognized Indonesian sovereignty.[7]
The city was officially renamed Bukittinggi in 1949, replacing its colonial name. From 1950 until 1957, Bukittinggi was the capital city of a province called Central Sumatra, which encompassed West Sumatra, Riau and Jambi. In February 1958, during a revolt in Sumatra against the Indonesian government, rebels proclaimed the Revolutionary Government of the Republic of Indonesia (PRRI) in Bukittinggi. The Indonesian government had recaptured the town by May the same year.
A group of Muslim men had planned to bomb a cafe in the city frequented by foreign tourists in October 2007, but the plot was aborted due to the risk of killing Muslim individuals in the vicinity.[8] Since 2008 the city administration has banned Valentine's Day and New Year's celebrations as they consider them not in line with Minangkabau traditions or Islam, and can lead to "immoral acts" such as young couples hugging and kissing.[9]

[edit] Administration

Bukittinggi is divided in 3 subdistricts (kecamatan), which are further divided into 5 villages (nagari) and 24 kelurahan. The subdistricts are:
Guguk Panjang, Mandiangin Koto Selayan, and Aur Birugo Tigo Baleh.

[edit] Transportation

Bukittinggi is connected to Padang by road, though a dysfunctional railway line also exists. For inner-city transport, Bukittinggi employs a public transportation system known as Mersi (Merapi Singgalang) and IKABE that connect locations within the city. The city also still preserves the traditional horse-cart widely known in the area as Bendi, although the use is limited and more popular to be used as vehicle for tourist, both domestic and foreign.

[edit] Tourism

It is a city popular with tourists due to the climate and central location. Attractions within the city include:
Sianok Canyon
  • Ngarai Sianok (Sianok Canyon)
  • Lobang Jepang (Japanese Caves) - a network of underground bunkers & tunnels built by the Japanese during World War II
  • Jam Gadang - a large clock tower built by the Dutch in 1926.
  • Pasar Atas and Pasar Bawah - traditional markets in downtown.
  • Taman Bundo Kanduang park. The park includes a replica Rumah Gadang (literally: big house, with the distinctive Minangkabau roof architecture) used as a museum of Minangkabau culture, and a zoo. The Dutch hilltop outpost Fort de Kock is connected to the zoo by the Limpapeh pedestrian overpass.
  • Museum Rumah Kelahiran Bung Hatta (Museum of Bung Hatta Birthplace) - the house where Indonesian founding father Mohammad Hatta was born, now a museum. [10]

topologi jaringan

Topologi jaringan merupakan gambaran perencanaan hubungan antar komputer dalam Local Area Network, yang umumnya menggunakan kabel (sebagai media transmisi), dengan konektor, ethernet card dan perangkat pendukung lainnya.

Jenis-jenis topologi jaringan
1. Topologi  Bus
    Topologi ini merupakan bentangan satu kabel  yang kedua ujungya ditutup, dimana sepanjang kabel terdapat node-node. Signal satu arah.
Keuntungan :
* murah, karena tidak memakai banyak media
* setiap komputer dapat saling berhubungan langsung


Kerugian  :
* sering terjadi hang /  crass talk

2. Topologi Ring
    Topologi jaringan yang berupa lingkaran tertutup yang berisi node-node. Signal dua arah. Semua komputer saling terhubung membentuk satu lingkaran. Tiap stasiun (komputer) dapat diberi repeater (transceiver) yang berfungsi sebgai  :
* Listen State : Tiap bit dikirim dengan delay waktu.
* Transmit State : Bila bit yang berasal dari paket lebih besar dari ring. maka repeater akan mengembalikan ke pengirim.
*By pass state : Berfungsi untuk menghilangkan delay waktu dari stasiun yang tidak aktif.

Keuntungan  :
* Kegagalan koneksi akibat gangguan media, dapat diatasi dengan jalur lain yang terhubung.
* Penggunaan sambungan point to point membuat transmission eror dapat diperkecil.

Kerugian :
* Data yang dikirim bila melalui banyak komputer, transfer data menjadi lambat.

3. Topologi Star
    Karakteristik jaringan ini adalah node (station) berkomunikasi langsung dengan station lain melalui central node, trafic node mengalir dari node ke central node dan diteruskan ke node(station) tujuan.

Keuntungan :
* Akses ke station lain cepat
* Dapat menerima workstation baru selama  port di central node tersedia
* Hub/switch bertindak sebagai konsentrator.
* Hub/switch dapat disusun seri
* User dapat lebih banyak

Kerugian :
* jika traffic data cukup tinggi dan terjadi colision, maka semua komunikasi akan ditunda, dan koneksi akan dilanjutkan dengan cara random, apabila hub/switch mendetect tidak ada jalur yang sedang dipergunakan oleh node lain.

4. Topologi Tree
    Tidak ada stasiun mempunyai kedudukan yang sama. Stasiun yang kedudukannya yang lebih tinggi menguasai stasiun dibawahnya, sehingga jaringan sangat tergantung dengan stasiun  yang kedudukannya lebih tinggi.

5. Topologi Mesh dan Full Connected
    Topologi jaringan ini menerapkan hubungan antar sentral secara penuh. Jumlah saluran harus disediakan untuk membentuk jaringan. Mesh adalah jumlah sentral dikurangi 1 (n-1, n = jumlah sentral). tingkat kerumitan jaringan sebanding dengan meningkatkanya jumlah sentral yang terpasang. Dengan demikian disamping kurang ekonomis juga relatif mahal.

6. Topologi Hybrid
    Topologi ini merupakan gabungan dari beberapa topologi yang ada, yang bisa memadukan kinerja dari beberapa topologi yang berbeda.
