Abstract

Generator sets are a combination of generators and drive engines combined into one unit to generate electricity. The drive engine in the generator set is generally an internal combustion engine either in the form of a motor / diesel engine with diesel fuel or an engine with gasoline. Some variants of pertamina diesel motorcycles commonly marketed in Indonesia are biosolar and Pertamina Dex. The fuel has a different centane value. The fuel at first glance looks the same, but has unequal characteristics. Comparisons that examined fuel, biosolar and pertamina dex get results if pertamina dex and biosolar have a lower fuel consumption value than diesel.  This study will compare the level of fuel consumption and effective power of biosolar fuel with pertamina dex and describe the results, with the aim that Pertamina fuel users have a valid data reference in determining better fuel choices.

Abstract

Low carbon steel has extensive use in the construction field and is grouped into steel which can be processed with machinery (machinery steel). The prominent weakness of this material is the type of failure that often occurs in low carbon steel materials is wear, deformation, chopping, and breaking. The purpose of conducting this research is to find out the process of carburizing on (wood charcoal and acacia wood charcoal) on low carbon steel.This solid carburizing process uses a temperature of 900OC, with a hold time of 30 minutes. The material used is a mixture of wood charcoal with calcium carbonate and acacia wood charcoal with calcium carbonate. Tests carried out were rockwell hardness tests.The test results showed that the hardness of carbon steel which experienced carburizing treatment with acacia wood charcoal = 51.65 HRB. Hardness found in low carbon steel without treatment = 50.3 HRB. Hardness of wood charcoal = 50.6 HRB. Judging from the results above, the low carbon steel without treatment is smaller than carbon steel which is heat treated and carburized.

Abstract

Caterpillar engines need to be completely reconditioned or general overhauled after operating and consuming a certain amount of fuel to restore engine performance to its specifications again. However, actual conditions can be faster or slower depending on the condition of the engine itself and operational needs. In the total reconditioning process, all seals, gaskets and bearings are normal spare parts that must be replaced, plus other spare parts that must be replaced based on the results of inspections and measurements in accordance with the guidelines from the caterpillar guidelines for reusability and salvage (GRPTS). The purpose of this research is to find out whether the reconditioned engine has reliable performance like a new engine from the manufacturer and of course refers to the engine performance specification number, as well as knowing the engine characteristics based on the application. The research stage is to carry out the total engine reconditioning process by disassembling, cleaning, inspecting, part listing, assemble, testing and adjusting engine performance specification. And for data retrieval, the engine is tested in the engine dynotest room with loadings of 25%, 50%, 75% and 100%. From the results of the engine after being reconditioned, it has performance like a new engine and deserves to be handed back to the customer to be operated according to its application and specifications with a maximum power achievement of 800 HP at 100% loading with 1800 rpm for industrial engine applications.
