Abstract

Today the development of technology is very rapid both in the field of basic science and the modification of a tool and even modifications in the field of engines, both combustion engines and electric engines. Modifications are needed to improve the performance of a machine. Modifications that can be applied to diesel engines that use fuels such as MFO, diesel, and biosolar. Diesel oil is the result of distillation of petroleum which is used only as fuel for compression ignition engines used by injectors. Biodiesel or biosolar is a type of fuel made from vegetable oil. The main objective of developing biodiesel is to substitute fossil fuels to produce green, environmentally friendly energy. The research we conducted was on the Caterpilar C15 Engine at PLTD Laiwui, and used biodiesel fuel (B30). Data collection is carried out when the machine is operating normally. From the data, we process it by analyzing it so we can find the main problem. From the results of the analysis, we get the root of the problem, namely the engine often shuts down because the pressure drops in the fuel system, this is caused by a dirty filter. From the results of the analysis, the researchers made a plan to modify the fuel system on the Caterpilar C15 engine at PLTD Laiwui. The modification applied is to add a material filter before entering the machine. then a performance test was carried out for 1 week and the modified data was compared with the initial data before the modification.

Abstract

Traditional drying of skipjack jerky is still widely used by MSMEs, but it is highly weather-dependent, prone to contamination, and produces less uniform quality. This research aims to design and test a prototype of an incandescent electric dryer that is simple to operate, provides controlled drying conditions, and is easy to use. The system developed is an insulated cabinet with stainless-steel mesh racks, incandescent light heaters, forced-air circulation, and temperature and humidity sensors, monitored during a 360-minute performance test with sample mass changes. The results showed that the drying chamber temperature remained stable at 43.9–49.3 °C, the relative humidity dropped from about 47% to ±30%, and the jerky mass decreased from ±917 g to ±353 g, with a final moisture content of about 30%. Compared to sun drying, electric dryers provide faster drying rates and more stable drying patterns, making the time to achieve the target moisture content and quality between batches more predictable. These findings show that the prototype is worthy of consideration as an alternative drying technology for seafood processing MSMEs and serves as a basis for further development to improve energy efficiency and product uniformity.
