Abstract

The PLTA TES is a generator that relies on water as the driving force for a turbine unit system. There are 7 PLTA Tes turbine units that are still operating with alternating working hours. In keeping a turbine unit operating properly, one way is to do maintenance and general inspection (GI). Maintenance is one way to keep a tool or object from being damaged. Then General Inspection (GI) is a process of activities in the PLTA Test company in checking, measuring, adjusting, repairing and testing one turbine unit in operating for 20,000 hours on a regular basis so that the unit can operate better than before, maintenance is carried out. One of the turbine components that is the object of maintenance is the runner. The runner is the heart of a turbine so that it can operate by relying on flowing water so that the runner can rotate. Runners are given a spot check to see if there is a crack in the runner's condition and measure the runner's clearance so that there is no excessive friction when the runner is operating and the runner is not thirsty.

Abstract

Energy is an important part of human life because almost all human activities always require energy. Therefore, it is necessary to conduct research to overcome the above problems, namely by making alternative energy by utilizing crumb rubber plant waste into alternative oil. The crumb rubber solid waste that we use comes from the micro blending and macro blending milling process from the process there is waste in the form of granulated rubber (Crumb Rubber Waste). Crumb Rubber Plant waste is currently not being utilized optimally. The basic structure of natural rubber is a linear chain of isoprene units (C5H8) natural rubber is a polymer of hydrocarbon compounds, namely 2–methyl-1,3 butadiane (isoprene). The main purpose of this study is to determine the value of the oil combustion rate resulting from the pyrolysis of crumb rubber solid waste and find out the characteristics of the oil resulting from the pyrolysis of crumb rubber solid waste and find out the comparison of the quality of oil from crumb rubber solid waste. From this study will show the optimum amount of pyrolysis and distillation results to produce oil. Operating conditions take place at atmospheric pressure with temperature variations of 200oC, 250oC, 300oC, and 350oC for 180 minutes for the pyrolysis process which will then be distilled with a temperature of 95°C for 20 minutes. The results showed that % of the conversion of raw materials into oil (amendment) was highest for the pyrolysis process at a temperature of 350oC of 51.86% while in the distillation process pyrolysis oil with a temperature of 350oC as much as 82.55%. For the value of the combustion rate in the largest pyrolysis process with a value of 0.975  at a temperature of 350oC and a distillation process of 1,612  at a temperature of 350oC.
