Abstract

Pinisi tourist ship is one of the tourist ship designs made to increase the interest of tourists to come to Taka Bonerate National Park. This tourist destination presents excellent maritime beauty, especially its coral reefs. Just like ships in general, pinisi also requires a supply of electricity, especially for use in lighting on board. This research aims to analyze the need for lighting power on board, by carrying out the concept of a tourist ship, the lighting system is also made like in a hotel with the aim of pampering tourists. In planning, the lighting system is made into two conditions, namely conditions during sleep and normal conditions. The type of lamp used is an LED lamp which is proven to be better than other types of lamps. The method used is the zonal cavity method or usually called the lumen method. The advantage of this method is that the power of the lights used in the room will be just right according to the needs of the room, neither more nor less, so it won't interfere with your eyesight because the lights don't feel dim or too bright. The results obtained were the following values for each Junction Lighting (JL), bottom deck (JL1) obtained a value of 0.419 kW, main deck (JL2) obtained a value of 1.058 kW, upper deck (JL3) obtained a value of 0.893 kW. The calculation value for the Junction Emergency (JE) was also obtained at 0.506 kW.

Abstract

This research endeavors to explore a novel alternative fuel source by combining waste used cooking oil and corn oil to create a biodiesel blend. The study addresses two main objectives: first, to investigate the properties of used cooking oil biodiesel with the addition of methanol and NaOH catalysts, and second, to assess engine performance using the biodiesel blend. The experimental approach employs transesterification, varying the catalyst quantity during biodiesel production. Preceding diesel engine testing, properties such as viscosity are assessed, revealing improved values meeting Indonesian National Standards post-catalyst addition, albeit with a decrease in calorific value. Engine performance is then evaluated, demonstrating that as the catalyst content increases, torque and thermal efficiency decrease, while specific fuel consumption (SFC) rises. Notably, the study concludes that a higher catalyst ratio aligns fuel properties closer to government-set standards. The most favorable engine performance is observed in the B50 sample with a catalyst variation of 1000 ml of methanol and 25 g of NaOH, showcasing superior torque, thermal efficiency, and opacity values compared to higher catalyst variations. This research underscores the importance of catalyst optimization in achieving an environmentally friendly biodiesel blend with enhanced engine performance.
