Abstract

One way to reduce the scarcity of fuel oil is to make environmentally friendly alternative fuels such as biodiesel. The utilization of biodiesel can be a new energy source and also help reduce the excessive use of fuel, especially diesel and diesel oil in Indonesia. In Indonesia, the amount of palm oil will reach 49.7 tons by 2021, and this data is up 2.9% from the pre-vious year. Palm fruit is processed into CPO. More palm oil processing will produce waste called POME (Palm Oil Mill Effluent). The diesel engine transesterification method is suitable for the manufacture of biodiesel. The amount of base on the catalyst's surface affects the catalyst's activity. So that the higher the base value on the catalyst, the higher the yield of biodiesel that will be produced. The biodiesel produced will be tested on a 4-stroke diesel engine with a B5 and B10 blending composition. The study's results showed that the density and viscosity values for B5 were 5.8 cSt and 810 Kg/m3 and for B10 were 6.3 cSt and 860 Kg/m3. As for engine performance, power, torque, and SFC for B5 fuel at 4000-watt load conditions and 1000 Rpm, engine speeds are 1.18 Kw, 11.28 Nm, and 256.8 gr/Kw. B10 at 4000-watt load condition and 1000 Rpm engine speed is 1.16 Kw, 11.12 Nm, and 269.2 gr/Kw.

Abstract

KMP Bambit is an Indonesian Ro-Ro ship that carries passengers. It is public transportation from Merauke Regency to Asmat Regency and vice versa. The ship is still using fluorescent lamps as its main lighting source. This study presents a comparative study of the efficiency level between the use of fluorescent lamps and LED lamps in the room aboard the ship. The method used is the zonal cavity (lumen) method by dividing each room into three parts, namely the height ceiling cavity (hcc), height room cavity (hrc), and height floor cavity (hfc). The illumination value was determined according to the standards set for each room. The principal results for comparing lighting power on KMP Bambit showed that the total lighting electrical load accumulated using the fluorescent lighting type was 24.31kW. In contrast, LED lighting had a total lighting electrical load of 16.51 kW. This reduced the generator power from 68 kW to 60 kW, which could improve the efficiency of ship fuel operational costs. This study can evaluate the existing Ro-Ro ship fleet and be a good option in the process of building Ro-Roships in the future.
