This research was conducted to obtain the optimal DG location with the aim of minimizing power losses in feeders. Penyulang Abang has a length of 207,946 kms with power losses of 1,105 MW. One way to reduce power losses is to install distributed generation. Distributed generation is installed in four Abang feeder locations. Optimization is done by using the Quantum Genetic Algorithm (QGA) method. Quantum Genetic Algorithm is an evolutionary algorithm. Genetic Quantum Method Algorithms are based on the concept of quantum bits (qubit) and the superposition of quantum mechanical forms. The purpose of this method is to select the best results from the results obtained. The final result of the QGA method is the most efficient distributed generation and capacity placed in several Abang feeder locations, namely buses 1, 5, 7 and 302 with capacities of 0.374 MW, 1,894 MW, 1,988 MW and 0.500 MW, respectively. So that the power losses are reduced to 0.234 MW.

The increasing demand for electrical energy in Bali requires additional electrical energy supply, while conventional energy such as petroleum, coal and natural gas continue to be used. Therefore, the utilization of non-conventional energy like solar energy should be increased. One of provision of non-conventional electric energy which is ready to be widely used is using PLTS Photovoltaic technology. The data analysis in this study uses manual calculation method to calculate electric power requirement, setting the result for electrical power, calculating the amount and capacity for solar module and inverter, calculating slope angle and location of solar module. PLTS uses a hybrid system with PLN, which works automatically to be controlled by the inverter control system. PLTS capacity of 148,274 kW supply 30% of the electrical energy consumption in the building of 2,310 MWh.

At present the power plant has a high dependence on energy sources such as diesel, natural gas and coal, while its energy source in nature is increasingly scarce, this situation encourages the development of renewable energy, one of which is in micro hydro power plants. This study aims to determine the effect of the width of the work triangle on the highest rpm produced. the fall of water on the pinwheel is set from the position angle of the nozzle 00, 150, 300, 450, 600, 750 and from the angle of the nozzle 00, 50, 100, 150, 200, 250, 300, 350 and 400 on the semicircular blade turbine, triangle blade turbine , and fin blade turbines. Semicircular turbine blade, working triangle area produces greater rpm at position of angle nozzle 00 and angle of nozzle 250 with area of work triangle 360,36 cm2, where the position produces 216 rpm at windmill rotation and 1626 rpm at generator rotation. When the nozzle position angle 150 and the nozzle angle 200 with the working triangle area 264.27 cm2, produce 221 rpm at the pinwheel rotation and 1711 rpm at the generator rotation. while at the nozzle position angle of 300 and the angle of the nozzle 100 the area of the triangle works 134.37 cm2 and produces 173 rpm at the spinning wheel and 1307 rpm at the generator rotation. on the triangle blade turbine and fin blade, the working triangle area does not affect the rpm produced.

There was many reliability system research with several research method. Each method have their adventages and disadventages, such as Section Technique method and RIA method. Section Technique method have adventage in its easy calculation, while RIA method use momentary failure rate parameter in its calculation so its final result almost similar to research place. Based on calculation result with Section Technique method found that SAIFI value of Kampus feeder network is 0,085 times / customer / years and SAIDI value of Kampus feeder network is 0,107 minutes / customer / years. After add momentary failure rate parameter to the calculatio, found that SAIFI value of Kampus feeder network is increase to 0,094 times / customer / years and SAIDI value of Kampus feeder network is increase to 0,162 minutes / customer / years.

The Microhydro Power Plant (MHP) is a small-scale power plant that uses hydropower. The most important component in a microhydro power plant is a turbine. The turbine used in this MHP model is the Archimedes screw turbine. In this research will discuss about the effect of water pressure on the rotation produced by Archimedes screw turbine so that it can be seen voltage, current, generated power by generator, torque and efficiency in modeling of MHP. Changes in water pressure given at 4 psi, 8 psi, 12 psi, 16 psi, 20 psi, and 24 psi. The highest measurement results are obtained at 24 psi water pressure, where the voltage, current, and generator output power is 85.8 Volt, 0.1963 Ampere and 16.85 Watt. For the rotation speed of the generator at 24 psi pressure is equal to 4582 rpm, while the speed of turbine rotation produced at 24 psi this pressure is equal to 383 rpm before coupled with generator and 222 rpm after coupled with generator. The torque and efficiency produced at 24 psi pressure are 0.73 Nm and 18.1%.

The dependence of power plants on energy sources such as diesel, natural gas and coal is almost 75%, encouraging the development of renewable energy in an effort to meet the electricity supply. One of them is the micro hydro power plant by utilizing the potential of existing water. The working principle of PLTMH is to change the potential energy of water into electrical energy. In this final project has been designed modeling of micro hydro power plant by using screw turbine (Archimedes Screw). The turbine used resembles a drill bit, with a diameter of a turbine of 26 cm, a screw width of 10 cm, and an amount of 10 pieces of blade. Measurements made on the modeling of micro hydro power plants include: water discharge, turbine rotation, generator rotation, voltage, current, torque and generator output power and efficiency. The parameters are measured by changing the water fall on the turbine from the position of the turbine head angle 00, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, 700, 800 and 900 . The result of measurement that has been done on the parameters of micro hydro power plant modeling, obtained the highest measurement result at the corner of turbine head 400. The output power generated is 10.92 watts, torque is 0.60 Nm and efficiency of 14%. The results obtained are still low because the turbine rotation is less able to rotate the generator, where the generator torque is greater than the torque in the turbine. This is influenced by the small water discharges in the modeling of this micro hydro power plant.

Rumah Sakit Umum Pusat Sanglah (RSUP) memiliki tingkat THD (Total Harmonics Distortion) arus yang tidak sesuai dengan standar IEEE 159-1992. THD arus yang berlebih dapat menyebabkan berbagai kekurangan. Untuk mengatasi masalah ini digunakan filter aktif shunt berbasis inverter. Dalam penelitian ini dilakukan simulasi penggunaan filter aktif menggunakan sofware simulink MATLAB 7.0.4 Hasil analisis menunjukan pemasangan filter aktif menyebabkan terjadi penurunan kandungan THD arus dan THD tegangan pada feeder yang bermasalah. Kandungan THD arus dan THD tegangan telah sesuai dengan IEEE 152-1992. Daya distorsi harmonisa pada sistem mengalami penurunan dan terjadi peningkatan faktor daya mendekati unity power factor pada feeder.
