Abstract

Oil palm empty fruit bunches (OPEFB) as a by-product of the palm oil processing industry. This waste can cause problems for the environment and human health. Utilization of OPEFB waste as particle board material to reduce this waste. The composition of the particle board is based on volume fraction, namely 15% empty palm fruit fiber, 15% epoxy resin, 20% PVAc adessive, and 50% sawdust. The manufacturing process of samples was carried out using the single punch cold press method with compaction pressure of 10, 30, and 50 bar. The experimental results show that a compacting pressure of 10 bar can produce particle board performance according to SNI 03-2105-2006 with a characteristic density of 0.93 gram/cm3, thickness swelling of 2.52%, hardness of 24 N/mm2, flexural strength of 840.05 N/mm2, and impact strength 6.00 kJ/m2.

Abstract

This is The Stirling engine is one of the alternative power generators that can be implemented at this time. The power generated by the Stirling engine can be used as a generator of electrical energy or for automotive applications. This study aims to determine the optimum performance of the stirling engine in power and torque by providing variations in temperature. The test temperature was carried out by providing energy from LPG fuel with varying temperatures, namely 200˚C, 300˚C, 400˚C, 500˚C, 600˚C and 700˚C. The data taken is RPM, power and torque. From the test results, for 200˚C is 16 W, for 300˚C is 30.66 W, for 400˚C is 45.72 W, for 500˚C is 67.5 W, for 600˚C is 81.06 W, for 700˚C is 105.27 W. In this study, a variant of changing the weight of the flywheel was also carried out. The test results show that an increase in flywheel weight of 1 kg causes an increase in RPM of 22.7% and power of 22.7%.

Abstract

One of the components used in power plants in boilers is the water heater. Of course, it has a very important role in the power plant. Its function is that it is very tight in the steam power plant, making the air heater work 24 hours, so its use is quite important. Knowing the function and usefulness of the Air Heater is important enough to require proper preventive. PT. Indonesia Power Suralaya PGU applies very strict Maintenance because of the losses experienced if the plant has damage which causes the unit to be forced to stop then the loss experienced is also very large. Preventive Maintenance performed on the Air Heater is done by looking at the condition visually and sound as the cornerstone of the repair analysis so that the treatment effort can be done well in terms of tightening, lubricating, and cleaning 32 minutes is the effective time an inspection is carried out whether there is significant damage or not. At the PM in the Air Heater found the effective run time every day is 2 hours 59 minutes when no indication of damage is found.
