Boilers that use low-quality coal result in an increase in the amount of coal burning and the high formation of accumulated ash deposits (fouling and salgging). It is necessary to conduct research the effect of fouling and slagging on boiler efficiency in steam power plant Moramo for the boiler performance improvement purpose. The objective of this research are identified fouling and slagging and how its affect boiler performance. By using the principle of mass and energy balance, heat transfer in the evaporator and superheater areas are used as the basis for identifying slagging and fouling. Boiler efficiency is calculated by a direct method. An increase in flue gas temperature which is affected by a degradation in the rate of heat transfer indicates the formation of slagging and fouling. Boiler efficiency is related to the slagging index and sodium content in the ash of coal, the result of higher slagging index and lower the sodium content will further increase boiler efficiency. The best average efficiency of boiler is 89.853% when coal from supplier Y used as fuel with slagging index value is 2370.2 and sodium content in ash is 0.48%..Keyword: Fouling, slagging, heat transfer, efficiency, boiler

Plastic is now a very important material and is widely used in modern life, but plastic processing is still a problem because the amount continues to increase, and pyrolysis is one solution. This research aims to design and test the performance of a three-level condenser on a plastic pyrolysis device and determine the results of the products produced.To find out the pyrolysis product from this design, a test was carried out, namely by heating the material (polypropylene/PP type plastic) in the design tool to a temperature of 450℃ and taking the data obtained after carrying out experiments on the design tool.Research shows that this three-condenser plastic pyrolysis device is effective in converting plastic into oil, with the best performance on larger plastic masses. The resulting oil has varying physical characteristics but is generally flammable at high temperatures, although it produces thick smoke and a strong odor.

At this time, fuel oil has become a basic need by the Indonesian people due to the increase in the use of vehicles, while the government is still subsidizing fuel oil. For this reason, it is necessary to save on the use of fuel oil. The alternative that can be done is reformulating fuel oil with additives that function to enrich the oxygen content in the fuel. The purpose of this study is to determine the performance of the engine which can be seen from the fuel consumption and acceleration of the vehicle in which the percentage of clove oil mixing which is most effective in its use will be known. This research includes mixing 1.5%, 2.5%, 3.5% and 4.5% mixture of clove oil to premium/gasoline. In this study, the formulation of a premium fuel/gasoline mixture with clove oil was most effective and efficient on fuel consumption, namely in the stationary test it was a mixture of 1.5% while in the running test it was a mixture of 2.5%. For the acceleration test, the best mixing formulation is in the 4.5% mixture formulation, both in the 0-70 km and 40-70 km tests.

PLTU Moramo is one of the Independent Power Producers (IPP) that supplies electricity to PT PLN. PLTU Moramo make use of turbine-generator with an installed capacity of 2x50 MW Steam Turbine - Full Condensing. PLTU Moramo Unit 1 experienced an increase in the condenser vacuum value after routine maintenance, the increase in the vacuum value affected to the heat rate and efficiency of the steam turbine cycle. The research conducted is to analyzes the effect of changes in the value of the condenser vacuum on the heat rate and efficiency of the steam turbine cycle by using a thermodynamic analysis approach and energy input-output methods. Data analysis uses actual parameters taken from the Distributed Control System (DCS) during normal operation. The results obtained in this study indicate that an increase in the condenser vacuum value affects the heat rate and efficiency of the steam turbine cycle, an increase in the vacuum value of -1 kPa results in a decrease in the average turbine heat rate of 57,673 kJ/kWh for a load of 40 MW Net and 93,575 kJ/ kWh for 50 MW Net load. Meanwhile, the average value of the steam turbine cycle efficiency increased by 0.37% for a load of 40 MW Net and 2.19% for 50 MW Net. Keywords: heat rate, efficiency, PLTU, vacuum
