Abstract

Designing appropriate technological innovations on the dc motor used to drive the alternator and knowing the performance of the tool. The method used in the research is the experimental design method which includes several stages, namely : (1) requirements analysis, (2) system design, (3) tool making, and (4) tool performance testing. This tool works using DC motor propulsion by rotating the alternator, so that it can rotate to produce an electric voltage which is then stored in an accumulator electrical energy storage cell. Electrical energy stored in batteries (accumulators) can be used to power electronic equipment on fishing vessels >10 GT such as GPS navigation tools, fishfinder lights, simple ones that do not have too much electrical power. Based on the results of the 20-minute test that has been carried out, it can be concluded that this appropriate innovative alternative power generation system can work well at 2000 rpm to 3600 rpm and produce an average voltage of 14.63 volts and an average charging current. - an average of 2.5 amperes.

Abstract

The caracteristic of plastic oil include density, viscosity and heating value Plastic waste can be used as raw material for plastic oil by usingpyrolysis process. The resulting plastic oil can be used as an additive or mixturefuel in the engine. In this research, the process of making plastic oil was used twicepyrolysis process. The reactor temperatures in the first and second pyrolysis processes are different respectivelynamely 200 oC and 150 oC. From the results of this research it is known that in the first pyrolysis processwith a reactor temperature of 200 oC, from 25 kg of raw material produces 15.5 liters of plastic oil intime 8 hours. Meanwhile, in the second pyrolysis process with a reactor temperature of 150 oC, from 15 liters of oilThe plastic from the first pyrolysis process produces 11.6 liters of plastic oil in 3.33 minutesO'clock. The characteristics of the plastic oil produced are a density of 771.4 kg/m3, Viscosity0.501 m2/s and calorific value 10518 kJ/kg.
