beli 2 oleh kemenhankam dari OCEA SA

ini adlh bagian dari hydro-oceanographic survey vessel

kelengkapannya: maritime surveillance, oceanographic equipment, yg kumpulkan topographical data utk pertahanan dan SAR.

juga: OCEA itu bikin OSV 190 SC-WB offshore survey vessels yg diminta TNI AL.
katanya menang kontrak dari 9 bidders: 3 SK, 1 GR, 4 FR tmsk OCEA dan 1 dari NL.
yg dari OCEA itu aluminium vessel. dan kontraknya: delivery of 2 vessels fully fitted for oceanographic & hydrographic research missions juga logistical support.

These ships are designed to study the waters and sea-bottom of the Indonesian archipelago and are therefore equipped with the most advanced technical and scientific equipment:
» An AUV (autonomous underwater vehicle by Kongsberg) capable of performing missions autonomously.
» An ROV (remotely operated underwater robot by ECA) which is involved in specific tasks.
» An 8 meter hydrographic craft equipped for data gathering along the coast in shallow areas. Designed by OCEA the two craft (one for each vessel) will be made in Indonesia.
» Several integrated sensors (fitted below the keel at the bow) allow data recovering and analysis.

Integrated logistics support associated with the contract consist in:
» Technical Documentation for operation and maintenance.
» Crew Training: Technical and Scientific (40 sailors per ship).
» Maintenance training (16 people per ship).
» On site technical assistance.

OCEA’s offer also included a specific formation: A Master’s degree in hydrographic science for an Indonesian engineer at ENSTA in Brest (Engineering school specialized in science and technology of the sea).

For the realization of this contract, OCEA works in partnership with the French Navy to optimize the positioning and the selection of scientific equipment and also to assist in the scientific training of crews and technical assistance to Indonesia.

These two ships are the first of an ambitious global project undertaken by the Indonesian Navy, which aims to develop its oceanographic and hydrographic fleet; OCEA’s goal is to become Indonesian Navy’s partner in the long term. In a country of more than 17 000 islands, the need is obviously very important as was shown during the recent operation for the crashed Air Asia passenger plane. The desire to develop maritime activity in the country has also been confirmed by the new President Jokowi.

OSV 190 SC-WB Mission:
The OCEA OSV 190 SC-WB is designed for maritime oceanographic and hydrographic research missions such as:
» hydrographic surveys.
» oceanographic studies.
» geophysical studies.
» Fisheries surveys.

To meet the multi-mission operational requirements, these ships offer the following performance and characteristics:
» Excellent sea-keeping.
» High maneuverability capabilities, stabilization and dynamic positioning.
» Endurance: 20 days.
» Ability to launch and recover research equipment and tele-operated robots.
» Ability to retrieve, store, and analyze samples (water, fish, sediment …).
» Lifting and towing capacity for a wide variety of specific equipment.
» Capacity to answer scientific requirements continuously (24/24, 7/7).
» Divers support.
» Ability to carry shipping containers (containerized missions).

Main Characteristics of the OSV 190 SC-WB:
» Overall Length: 60.10 m
» Width: 11.50 m
» Draft: 3.50 m
» diesel capacity: 135,000 l
» Water capacity: 35 000 l
» Maximum speed: 14.0 knots (2 x MTU 8V4000M53 engines)
» Crew: 40 sailors
» Passengers and VIP Capacity: 11 people

A high-ranking Navy official revealed that the cost of a warship unit is Rp 500 billion (around US$38.5 million). Rachmad Lubis, head of the MoD’s Defence Facilities Agency, told reporters that the contract, worth USD100 million, was signed in October 2013 following negotiations between French and Indonesian government representatives.

The ship will also be assigned for search and rescue missions because it comes equipped with an AUV (autonomous underwater vehicle) to take underwater images up to a depth of 1,000 meters and send data periodically.
The new ship is also equipped with remotely operated vehicle (ROV) or an underwater drone equipped with mechanic arms to provide visual information and take samples from the bottom of the ocean.

Hydrographic survey

A hydrographic survey ship is a vessel designed to conduct hydrographic research and survey. Nautical charts are produced from this information to ensure safe navigation by military and civilian shipping.

Hydrographic survey vessels also conduct seismic surveys of the seabed and the underlying geology. Apart from producing the charts, this information is useful for detecting geological features which are likely to bear oil or gas. These vessels usually mount equipment on a towed structure, for example, air cannons, used to generate a high pressure shock wave to sound the strata beneath the seabed, or mounted on the keel, for example, a depth sounder.

In practice, hydrographic survey vessels are often equipped to perform multiple roles. Some function also as oceanographic research ships. Naval hydrographic survey vessels often do naval research, for example, on submarine detection.

An example of a hydrographic survey vessel is CCGS Frederick G. Creed. For an example of the employment of a survey ship see HMS Hydra.

Oceanographic research

Oceanographic research vessels carry out research on the physical, chemical and biological characteristics of water, the atmosphere and climate, and to these ends carry equipment for collecting water samples from a range of depths, including the deep seas, as well as equipment for the hydrographic sounding of the seabed, along with numerous other environmental sensors. These vessels often also carry scientific divers[2] and unmanned underwater vehicles. Since the requirements of both oceanographic and hydrographic research are very different from those of fisheries research, these boats often fulfill dual roles.

Examples of an oceanographic research vessel include the NOAAS Ronald H. Brown and the Chilean Navy Cabo de Hornos.[3]

Fisheries research

A fisheries research vessel (FRV) requires platforms which are capable of towing different types of fishing nets, collecting plankton or water samples from a range of depths, and carrying acoustic fish-finding equipment. Fisheries research vessels are often designed and built along the same lines as a large fishing vessel, but with space given over to laboratories and equipment storage, as opposed to storage of the catch.

An example of a fisheries research vessel is FRV Scotia.

Naval research

Naval research vessels investigate naval concerns, such as submarine and mine detection, sonar and weapon trialling.

An example of a naval research vessel is the Planet of the German Navy.

Polar research

Polar research vessels are constructed around an icebreaker hull, allowing them to operate in polar waters. These boats usually have dual roles, particularly in the Antarctic where they function also as polar replenishment and supply vessels to the Antarctic research bases.

An example of a polar research vessel is USCGC Polar Star.

Oil exploration

Oil exploration is performed in a number of ways, one of the most common being mobile drilling platforms or ships that are moved from area to area as needed to drill into the seabed to find out what deposits may or may not lie beneath it.


KRI Rigel-933 bersandar di Sabang. Saat penjemputan, kapal itu didampingi dua kapal milik TNI AL, yang akan menyambut KRI Rigel-933 di Sabang

Tanjungpinang (Antara Kepri) – Tim Gugus Tempur Laut Armabar TNI AL Rabu (6/5) akan menggelar tradisi penjemputan terhadap KRI Rigel-933, buatan Prancis, kata Perwira Penerangan Armabar, Mayor Agus SK, di Lanudal Tanjungpinang.

“KRI Rigel-933 bersandar di Sabang. Saat penjemputan, kapal itu didampingi dua kapal milik TNI AL, yang akan menyambut KRI Rigel-933 di Sabang”, tambahnya.

Tim dari Armabar dan Dispen AL tiba di Tanjungpinang tadi sore dengan menggunakan Pesawat CN-235-220 MPA TNI AL. Pesawat ini biasanya digunakan untuk mengintai dari udara kondisi kemaritiman di Indonesia.

Tim tersebut membawa beberapa jurnalis televisi dan foto. Mereka akan menggunakan pesawat yang sama menuju Batam, kemudian langsung ke Sabang.

KRI Rigel-933, kata Agus, memiliki spesifikasi teknis sebagai kapal bantu hidro-oseanografi (OSV 190 SC-WB). Secara umum kapal itu memiliki kemampuan “multy purpose research vessel” seperti survei hidrografi, survei oseanografi, survei geofisika dan survei perikanan.

Kapal itu memiliki daya tahan di laut 20 hari untuk 46 personel dengan kecepatan maksimum 14 knot.

“Jarak jelajah mencapai 4.400 NM pada kecepatan 12 knot state 0-1. Klasifikasi dikeluarkan oleh Bureau Veritas (Prancis),” katanya.

Agus menjelaskan semua material badan kapal menggunakan “marine grade alluminium alloy” dengan pembagian plat kapal menggunakan “alluminium alloy grade 5083”, tulangan tekan menggunakan “alluminium alloy Grade 6005” dan memiliki tujuh dinding kedap dengan delapan kompartemen.

“Geladak kerja dilapisi ‘removable wood’ setebal 45 mm, memiliki dua ‘boarding deck’ untuk mempermudah akses ke belakang geladak ‘main deck’. Pengelasan menggunakan spesifikasi standar dari BV,” katanya. (Antara)

ternyata bppt bikin kapal baruna jaya 1-8 juga kapal maruta jaya 900 (yg tenggelam hadoh, dasar ini negara belegug).
kemudian wkt rame airasia kita gunakan crest-onyx

program std nya biasanya trdr dr system dan user, mis berisi configure_oscillator (dg sys freq didefinisikan ke 7 jt 370rb dan fcy itu sys freq dibagi 4) dan init_app. di init_app mis kt setup fungsionalitas analog dan arah port lanjut dg init’ze periferal, ini kt jdkan tugasnya: grup lmpg, sedangkan sys kt masukkan grup kng.
skrg utk grup kng:
available osc config ada di dokumen device family, biasanya ada tuning register atau clock switchng yg bs dioprek dg fungsi builtin: __builtin_write_OSCCONH dan __builtin_write_OSCCONL (high & low utk ucu vs unu) ini utk set konfigurasi osc utk clock switch dan start proses clock switch…lalu baca OSCCONbits.COSC (cosc: sakri) apakah sudah sama dg 0b011? jk tidak noop. jk lewat: tunggu sebentar abis itu tunggu PLL utk ngelock (jk ada) dan baca OSCCONbits.LOCK (lokusendang) apakah sudah sama dg 1?
lalu sbg ‘pelengkap’ adlh interrupts, traps, dan configuration bits. ini kita kasihkan ke siapa ya???

kita jg biasa include p30Fxxxx.h

coba cek nih board dan programmer, apa kurang adapter?

kita lihat dulu dspicdem 1.1+ gpdb: kalo ngelihat webnya, yg sedikit bikin ribet adlh adanya 2 jenis dsp: dspic-30f6014a dan -33fj256gp710. mana yg dipake? klo lihat plug-in module supported disebutkan bhw dia dukung dspic-30f6014a, -30f6010a, dan -33fj256gp710, dg demikian krn jelas2 yg terpasang adlh yg pertama, kt jd gnkan yg prtma jg.
source antara .s atau .c lalu tambahkan linker script .gld yg dukung spesifik board, abis itu jadi hex dan cof. hex berisi data diperlukan utk memrogram divais dan cof berisi info tambahan yg bs bantu debug pd source code level, perbandingan cof 60ribu dan hex 4rb aka 16x lipat ukurannya.

No kernel no cry

jk perangkat blok itu bs open, read, write, dsb, dan punya entry di /dev/, perangkat jaringan sih gak masuk akal utk lakukan itu, maka dia hidup di dunia sendiri dan operasi2 sendiri. waluapun kita lihat operasi spt read, write ke soket tp di sini kita bicara dg ‘software construct’ bukan perangkat jaringan yg sebenarnya. perbedaan mencolok atr kedua perangkat ini adlh jk yg satu beroperasi/hidup/beraksi atas permintaan dari kernel, perangkat jaringan itu beraksi berdasarkan kedatangan paket dari luar negeri yg gak jelas juntrungannya. yg satu minta ‘hey, tolong dong kirimkan ini kue dan minuman dari ku untuk nya, kau jadi kurir ya’, sedangkan yg jaringan itu ‘hey, aku mau kasih kamu sesuatu krn kamu itu spesial’. selain operasi2 yg berhubungan dg meat kerjaannya, perangkat jaringan jg berurusan dg birokrasi spt ngeset alamat, oprek sejumlah parameter, tulis/log statistik jaringan dll.

subsistem jaringan dibikin sedmikian rupa shg transparan thd protokol yg akan digunakan, baik protokol jaringan maupun protokol hardware, layer 3 atau layer 2. interaksi antara driver/supir satu perangkat jaringan bersama dg sang maestro kernel itu berkutat seputar satu paket jaringan dalam satu waktu. kehidupan seekor paket dari mulai datang sampai dikonsumsi dan dibuang ampasnya oleh kernel itu panjang dan lebar…spt kelahiran bayi sampai dia lulus kuliah, mendapat pekerjaan dan berumahtangga. kita bicara protokol (layer 3) dan bicara hw/fisik (layer 2 atau 1), dan kita gak pengen permasalahan di satu domain/layer menerobos ke domain lain, hrs terpisah scr rapi dan transparan.

on microwave

kt sbt sj mw amplifier dan mw oscillator itu mwa dan mwo. mwa digunakan di siskom spaceborn dan sistem radar airborne. mwo rancangannya lebih susah dari mwa. juga mtl utk microwave transmission line.

yvg pertama kt bhs dlm 2-conductor transmission lines adlh apakah pd TL itu, pada masing2 terminalnya, karakteristik impedancenya termatched dg benar? knp perlu matching (technique)? utk kurangi SWR, yg artinya kita pengen efisiensi lebih tinggi.

ada bbrp jenis TL:
1) 2-wire line…berisi 2 parallel conducting wires dipisah jarak yg sama, contoh kabel listrik dan kabel telepon. krn ktia punya 2 kawat yg berdekatan dan arus pd kedua kawat yg terconfined ke adjacent surfaces maka medan (listrik) yg dihasilkan akan meleber keluar kawat (jauh) dan kerugian akibat radiasi akan membesar dg meningginya freq. jd max dia hanya digunakan smp bbrp ratus mhz saja.
2) coax-line…ini ada inner conductor dan concentric outer conducting sheath dipisah oleh media dielektrik. EF dan MF diconfied keseluruhannya ke dalam daerah dielektrik. kerugian akibat radiasi sangat kecil. contoh kabel telpon dan kabel TV.
3) striplines…terdiri dari 2 parallel coplanar strips terpisah oleh dielektrc slab dg ketebalaan sama. contoh parallel striplines, microstrip lines, coplanar striplines, digunakan misal di microwave IC
4) optical line…terdiri dari inner core dg indeks refraksi lebih tinggi dikelilingi oleh outer cladding yg indeks refraksinya lebih rendah. loss krn radiasi sngt rendah dan aplikasi utk jaringan backbone dll.

ada lumped-circuit theory vs distributed-circuit theory, lct itu kira2 jk tiap komponen (dsbt line params) spt R, L, C bersifat statik dan tdk bergantung pd frek atau fasa jalur transmisi, sedangkan dct itu jk dia adlh fungsi dari frek atau fasa.
dlm microwave, frek tinggi, jadi wavelength pendek, dan terutama jk dibadingkan relatif thd panjang jalur transmisi, dg alasan ini katanya kt gak bs gunakan lct utk analisis mlt. kt hrs analisis mlt menggunakan voltage, current, impedance menggunakan dct. jk wavelength (dari frek sinyal yg dilewatkan) relatif lebih panjang dari ‘spacing btw the lines’ maka kita perlu analisis mlt sbg waveguide.
utk nganalisis mlt kita bisa gunakan yg namanya metode2 dari dct atau menggunakan solusi dari persamaan medan maxwell. perbedaannya, yg pertama 1 space var + 1 time var, yg kedua 3 space var + 1 time var.

solusi umum utk persamaan TL  terdiri dari 2 gelombang berjalan dg arah berlawanan dan besar/amplitudo yg berbeda…bs dinyatakan dg ….
standing wave sendiri dihasilkan dari keberadaan scr bersamaan atr gelombang berjalan berlawanan pd TL. ratio dari max dan min = SWR. SWR disebabkan oleh fakta bhw 2 komponen gelombang berjalan ‘bertemu fasa’ pd satu titik dan saling berselisih…jarak 2 maxima dan minima berurutan adlh lambda/2.

waktu bicara soal smith chart, sc dan compressed smith chart, csc. ada istilah reflection coefficient, rc. rc bisa kurang dari unity atau lebih dari unity, utk yg pertama artinya line resistance (lires) positif sedangkan yg kedua itu lires negatif. utk yg pertama kita gunakan sc, yg kedua csc. tujuan penggunaan sc adlh krn solusi persamaan TL terlalu rumit, gunakan grafik bs sampai ke jawaban scr lebih cepat.
sc terdiri dari a plot dari normalized impedance atau admittance…dg angle dan magnitude dari generalized cmplex rc…in a unity circle…chart nya bs digunakan utk lossless ataupun lossy line.
