Abstract

Penempaan (forging) adalah proses pembentukan logam secara plastis dengan mempergunakan gaya tekan untuk mengubah bentuk atau ukuran dari logam yang dikerjakan. Proses tempa ini bias dilakukan dengan 3 cara yaitu pengerjaan dingin (cold working), pengerjaan hangat (warm) dan pengerjaan panas (hot working) dimana parameter dasarnya adalah temperature rekristalisasi. Tujuan Penelitian Perencanaan Mesin Tempa Logam Dengan Sistem Forging Hammer adalah untuk mempermudah pekerjaan manusia untuk meningkatkan produktifitas dan waktu yang relative cepat. Mesin ini menggunakan daya yang dihasilkan oleh motor listrik, karena adanya daya motor listrik sehingga poros dapat berputar dan berfungsi sebagai pemutar noken penekan, sehingga lengan ayun dan hammer / palu  naik turun  menempa logam material. Cara kerja mesin tempa logam dengan sistem forging hammer, digerakkan oleh mesin listrik melalui pulley dan sabuk menghasilkan lengan ayun dan hammer (palu) turun naik sehingga menempa logam material dengan bentuk yang diinginkan. Daya motor mesin tempa logam dengan sistem  forging hammer ini menggunakan daya 1 HP dengan 2900 rpm dan diameter poros lengan ayun ∅12 mm dan diameter noken penekan  ∅35 mm, panjang lengan ayun 650 mm dan tinggi palu 136,5 mm dengan berat 2 kg, untuk hasil mesin tempa logam, mesin ini mampu menempa logam material Plat ST 37 dengan ketebalan 3 mm sampai 5 mm.

Abstract

Semen Padang Indarung IV unit has a screw compressor type compressor unit to produce high pressure air. In its operations, one of the Atlas Copco type compressor units often experiences over heating problems, namely the working temperature exceeds 1000 C. The method used is trouble shooting the compressor system, such as checking the lubricating oil, pressure, valves, working temperature and cooling system. , as well as overhaul maintenance actions if necessary. Based on the research results, it was found that the factors that cause overheating of the compressor are: Dirty air quality affects the condition of the air filter for air supply, limited space for placing the compressor causes the air supply to decrease, the oil filter has passed its useful life and is not suitable for use, and the oil cooler is clogged with scale, which hinders the oil cooling process. Based on this damage, recommendations for maintenance activities on the Atlas Copco Compressor are: maintaining air quality, periodically cleaning the tubes in the oil cooler, replacing the new oil filter according to compressor specifications, as well as comprehensive maintenance measures

Abstract

Compressor is one of the equipment on the ship in the process of smooth sailing for the purposes of starting the main engine and also functions to increase gas pressure, distribute air to other parts so that the process runs smoothly. MT Tanker Ship. Sea Serenity is a goods delivery ship. On this ship, the compressor is used to carry out maneuvers, namely the main air compressor which produces air pressure of 12 bar for 10 minutes, but it should only be 5 minutes, meaning the compressor performance is not optimal. The causes of decreased performance in the compressor are: Dirty/clogged air valve, wear of the piston ring/housing, non-functioning of the low pressure and high pressure suction valves. Recommendations for maintenance activities on the LSHC-50A air compressor are: Ensure air circulation to the compressor room is clean/free from dust or dirt, add an air filter, and maintain room temperature stability (providing air conditioning). Maintain the cleanliness of the blower, check the oil filter, replace damaged pistons, and replace new piston rings according to compressor spare parts every 6000 working hours

Abstract

The design of this metal burning stove was made to speed up and make it easier for blacksmith craftsmen to produce quality products. Using this tool, blacksmith craftsmen can produce a stable flame in the metal burning process. Where the planning for a metal burning stove uses coal as the main fuel, because coal can produce a longer lasting fire compared to charcoal or firewood. The working principle of this metal burning stove is to use a machine tool that is driven by a blower to increase or enlarge the air or gas pressure that will transmit to the connecting pipe, and produce a stable fire so that combustion is faster and more efficient. The metal burning furnace planning process consists of: Power planning in the metal burning furnace planning p_d = 0.3 Kw, using a blower with a rotation of 2800 rpm, using 2 pipes as air conductors, the furnace volume is 7,385.28 m^3 and using a C18 castabble, weight 25 kg, cement resistance capacity 1800?.
