Kegiatan eksplorasi saat ini semakin gencar dilakukan. Teknologi pun mengiringi dengan berkembang sangat pesat. Pendorong sliding rig sebagai salah satu alat yang dianggap lebih efektif dan murah dibandingkan melakukan rig up dan rig down untuk memindahkan rig pada sumur berjenis cluster well yang berjarak antar sumur 10-20 m . Kelebihan penggunaan sliding rig dibanding dengan tidak menggunakan sliding rig dalam memindahkan rig adalah proses pemindahan rig menjadi lebih cepat karena tanpa melakukan pembongkaran rig. Ada dua tipe alat pemindah rig, yaitu rig walker dan sliding rig. Di Indonesia, sliding rig lebih aman untuk digunakan karena operasinya yang mudah dan murah. Salah satu sistem dalam pendorong sliding rig adalah sistem hidrolik. Sistem ini memiliki fungsi sebagai komponen utama untuk mendorong rig. Adapun yang perlu diperhatikan dari sistem hidrolik adalah material lower dan upper load (pony sub pada rig dan H-beam), spesifikasi sistem pelumasan pada komponen yang bergesekan (pony sub dan H-beam), spesifikasi dan aksesoris hidrolik, analisis stabilitas rig ketika dipindahkan oleh pendorong sliding rig, spesifikasi konfigurasi sistem hidrolik, dan pemilihan material dan dimensi H-beam.
Exploration activities currently carried out more intensively. The technology was accompanied by growing very rapidly. Sliding rig pusher is the one of the tools that are considered far more effective and cheaper than doing rig up and rig down to move the rig for the cluster wells that the distance between wells is about 10-20 m. Advantages of use of a sliding rig if it is compared to not using a sliding rig pusher to move the rig is the process of moving rig to be faster because without disassembling rig. There are two types of a transporter rig, that is rig walker and sliding rig. In Indonesia, a sliding rig is safer to use because its operation is easy and inexpensive. One of the systems in the sliding rig is hydraulic system. This system has a function as the main component driving rig. As to consider are lower and upper load material rig (pony sub rig and H-beam, lubrication system for parts that rub against each other, specification of the hydraulic system, rig stability analysis when the rig is moved by sliding rig pusher, hydraulic system configuration, the selection of H-beam dimension and material.

Pengelasan merupakan metode yang sering digunakan pada proses manufaktur dari kendaraan taktis. Pengelasan dengan menggunakan metode gas metal arc welding(GMAW) umum dilakukan pada paduan aluminium, dikarenakan minimnya kontaminasi dari udara dan memiliki kecepatan pengelasan yang tinggi karena elektroda terumpan secara kontinyu. Pada penelitian ini dilakukan pengelasan dengan metode GMAW pada pelat komposit Al-10Zn-6Mg-3Si yang diperkuat oleh 10 %Vol. SiC dengan menggunakan metode squeeze casting. Parameter yang digunakan adalah arus, yaitu sebesar 180, 210, dan 240 A, dengan variabel tetap tegangan sebesar 22 V, dan kecepatan pengelasan sebesar 180 mm/menit. Didapatkan variasi heat input sebesar 1.32, 1.54, dan 1.76 kJ/mm. Pengujian yang dilakukan antara lain uji tekuk, uji keras, SEM, dan metalografi. Hasil yang didapatkan adalah dengan penambahan heat input pada proses pengelasan, kekerasan yang didapatkan semakin menurun karena dengan penambahan heat input akan memperlambat pendinginan sehingga memperbesar butir.Ditemukan fasa Al4C3 pada pengujian SEM, yang mengakibatkan penurunan kekuatan dari produk pengelasan. Fasa tersebut didapatkan dari reaksi Al dengan SiC pada temperatur diatas 700oC, sedangkan temperatur pengelasan mencapai 2000o C.
ABSTRACT
Welding is one of the most common method used in joining ballistic vehicle body structure. Welding with gas metal arc welding (GMAW) is widely used for joining aluminium alloy because of its low atmosphere contamination and continously feeding electrode that results in high welding velocity This research studied GMAW of Al-10Zn-6Mg-3Sicomposite reinforced by 10 %vol. SiC, produced by squeeze casting method. In GMAW, the current is varied to 180, 210, and 240 A, with constant voltage and velocity of 22 V and 180mm/min, respectively. Therefore heat input used in this research is varied to 1.32, 1.54, 1.76 kJ/mm. The characterization included bending test, microhardness test, dan metallography observation. The result shows that the higher heat input will decrease the hardness because it slowed down the cooling rate so that increased the grain size. Al4C3 was found on SEM observation, which decreased the strength of the weld products. Al4C3 was produced by the reaction of Al with SiC at 700 oC, which was lower than the welding temperature that exceed 2000 oC.;Welding is one of the most common method used in joining ballistic vehicle body structure.

Efek rumah kaca adalah salah satu penyebab perubahan iklim dunia. Penggunaan kendaraan bermotor dengan bahan bakar fosil menjadi salah satu penyumbang polusi dan pemanasan global. Alasan lain mengapa ketergantungan akan bahan bakar minyak harus dikurangi adalah kecilnya cadangan minyak bumi Indonesia dibandingkan dengan negara OPEC lainnya. Cadangan tersebut pun kini cenderung terus menipis tiap tahunnya.Para peneliti berusaha mengantisipasi hal ini dengan mengembangkan kendaraan tenaga listrik yang mampu beroperasi tanpa menimbulkan polusi. Penerapan kendaraan listrik telah dimulai dengan adanya kereta listrik, trem, bis listrik, dan lain-lain. Kendaraan dengan rel mendapatkan pasokan listrik dari jala-jala listrik sepanjang rel, namun jenis kendaraan yang bergerak bebas tanpa rel memerlukan cara lain untuk mendapatkan pasokan listrik. Hasil riset secara sosial menyatakan bahwa pegembangan bis listrik adalah strategis untuk Indonesia.Kendaraan listrik dengan penyimpan daya battery memiliki keunggulan dalam area jelajahnya jika didukung dengan teknik pengisian ulang yang baik. Pada kendaraan listrik, battery diisi ulang dengan proses charging atau ditukar dengan battery lainnya yang telah diisi ulang swapping . Jika kendaraan memiliki mobilitas tinggi, misalnya angkutan umum bis maka lama waktu pengisian sesingkat mungkin sangatlah penting. Semakin cepat process charging maka semakin menguntungkan.
The increase of greenhouse gasses effect is one of the causes of climate change. The use of vehicles with fossil fuels is one of the contributors to pollution and global warming. Another reason why dependence on it should be reduced is the lack of Indonesia 39 s petroleum reserves compared to other OPEC countries. The reserves are now likely to continue to deplete every year.Researchers are trying to anticipate this by developing electric vehicles capable of operating without pollution. Implementation of electric vehicles has begun with the electric train, tram, electric bus, and others. Vehicles with rails get electricity supplies from the grid along the tracks, but the type of freely moving vehicle without a rail requires another way to get electricity supplies. Electric vehicles with power storage battery have an advantage in the roaming area if supported by proper recharging techniques. In electric vehicles, the battery is recharged by the direct charging process or swapped with other one swapping . If the vehicle has high mobility, such as public transport bus then the shortest charging time may be very important. This study and trial aims to determine the pattern of power consumption on the electric bus and the reliability of the system. Thus the data obtained for further study related to the way of recharging the battery and improvement bus work system.
