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

This study compared the length of time and of the enumeration results on the blades before they were modified and after modified. Variations in waste weight were 250gr, 500gr, and 750gr. The results showed that the percentage comparison of the length of the process of enumerating plastic waste before modification with the weight of 250gr resulted in enumeration time for 35 seconds, so that the effective capacity of the tool was 25.71 kg / hour. For weight of garbage equal to 500gr produce enumeration time for 126 second, with tool capacity 14,28 kg/hour. While the weight of garbage 750gr produce enumeration time for 192 seconds, with the effective capacity of the tool of 14.06 kg/hour. For the conditions after modification of the blades, the weight of the waste of 250gr resulted in an enumeration time of 80 seconds, in which the effective capacity of the apparatus was 11.25 kg/hr. For the weight of garbage of 500gr was resulted enumeration time for 255 seconds, where the effective capacity of the tool obtained was 7.05 kg/hour. While the weight of 750gr garbage generates the enumeration time for 401 seconds, where the effective capacity of the tool obtained of 6.73 kg/hour. The quality of enumeration of plastic waste on the blades before the modification was still not chopped properly, while the results of plastic waste debris on the blades after modified has been chopped well but the results were not irregular.

Energy is a fundamental need that is increasing every year. Dependence on fossil fuels, such as limited LPG and an increasingly threatened environment encourages the development of renewable energy sources. This study aims to examine the feasibility of rice husk energy potential as an alternative fuel to replace LPG in the South Konawe Regency. A survey was conducted to determine the pattern of rice husk utilization at the community level at several rice milling locations in South Konawe Regency. Data analysis was carried out using data obtained from BPS Southeast Sulawesi and BPS Konawe Selatan Publications (2018-2022). By calculating the estimated energy potential of rice husks and energy consumption of LPG use, and forecasting until 2025 using the Double Exponential Smoothing method from Holt. The results of the data analysis show that the average energy potential of rice husks (2018-2022) is 236,124.56 (GJ), and LPG energy consumption (2018-2022) is 365,625.83 (GJ). For forecasting the energy potential of rice husks in 2025 amounting to 277,863.22 (GJ), and forecasting LPG energy consumption in 2025 of 363,968.39 (GJ). In conclusion, the energy potential of rice husks can distribute around 65% of the total LPG energy needs of households in South Konawe Regency. Keywords: Biomass, renewable energy, rice husks

Water transfer in inland areas is still done manually, so we need a water pump with efficiency, technology, economy without the use of electricity and fuel, namely a hydram pump. A hydram pump is a water pump that relies on the momentum of water to raise water. The purpose of this study was to determine the effect of inlet pipe size on pump efficiency, outlet pipe flow rate and the effect of pipe joints on major and minor losses. This research was made with a water source height of 1 m, varying inlet pipes measuring ¾ inch, 1 inch, and 1,5 inch with a length of 5 m, a hydram pump body with a diameter of 1 inch, an air tube with a diameter of 3 inch with a length of 40 cm and an outlet pipe measuring ½ inch. The largest hydram pump efficiency is found in the ¾ inch inlet pipe with 1.94% with an outlet pipe flow rate of 1.79 l/min and the lowest efficiency is in a 1 inch inlet pipe with 1.49% with an outlet pipe flow rate is 1.55 l/min while the major value and the biggest loss value are in the ¾ inch inlet pipe with values of 0.00754 m and 0.678 m and the lowest values are in the 1.5 inch inlet pipe with values of 0.000410 m and 0.019 m so that it can be concluded that the cross-sectional area and the number of connections in the hydram pump installation are very influential on the value of major and minor losses.Keywords: Diameter, Waste Valve, Pipe, Pump
