Penggunaan energi listrik semakin meningkat. Genset dapat digunakan apabila pasokan listrik terganggu. Akan tetapi, genset ini membutuhkan bahan bakar minyak yang banyak jika dijalankan dalam jangka waktu yang lama. Penggunaan bahan bakar minyak atau bahan bakar lainnya seperti batu bara tidak dapat dilakukan tanpa adanya perkiraan penghematan, karena sumbernya terbatas dan semakin menipis. Untuk mengantisipasi menipisnya sumber daya bahan bakar alam, maka dilakukan penghematan dan pencarian bahan bakar alternatif yang sumbernya dapat diperbarui seperti tenaga surya, angin, air, dan gelombang laut serta biofuel. Sumber-sumber energi terbarukan tersebut dapat dikelola untuk menghasilkan energi listrik dengan merancang teknologi tepat guna sebagai pembangkit listrik seperti pembangkit listrik tenaga angin, pembangkit listrik tenaga surya, dan pembangkit listrik tenaga air. Edukasi dilakukan kepada masyarakat sekitar kampus USK tentang penghematan penggunaan energi listrik serta pemanfaatan dan pengenalan beberapa sumber energi terbarukan dan pengenalan beberapa pembangkit listrik yang menggunakan energi terbarukan.

This study evaluates the efficiency performance of the motor-pump system used by the regional water utility company to identify strategies for improving efficiency. The three-phase induction motor utilized is highly dependent on the quality of the supplied voltage. The primary focus of this research includes analyzing the efficiency performance of the system, examining the electrical parameters of the three-phase induction motor, which include voltage and current imbalance, power factor, and Specific Energy Consumption (SEC). Another focus is the optimization of the motor-pump system and estimating the potential energy savings and operational cost reductions achievable within one year. The research method involves measuring electrical and hydraulic parameters. Electrical parameters were measured using a 3-phase power analyzer (type DW-6195), which records current, voltage, frequency, power, and power factor. Hydraulic parameters were measured using an electromagnetic flow meter for flow rate readings, a manometer for pressure measurements, and a measuring tape to measure the water level in the reservoir tank. All measurement results were tabulated and further analyzed to evaluate the performance of electrical parameters and compare them to the hydraulic performance of the system. The results revealed that the efficiency of the PDAM motor-pump system is below 50%, indicating the need for a comprehensive system revitalization. An inspection of electrical parameters showed that voltage deviation is below 10%, voltage imbalance is below 5%, and current imbalance ranges between 5.65% and 7.35%. All electrical parameters comply with IEEE standards. The power factor, at 0.85, also meets electrical standards. The SEC value, below 0.44 kWh/m³, indicates potential energy efficiency. Based on the pump performance curve study, the pump system can be replaced with a pump unit that has a lower electrical power rating, reducing it from 75 kW to 55 kW, while maintaining its hydraulic performance. Implementing this revitalization is expected to save up to 172,800 kWh of energy per motor per year and reduce by 18.4%.

The need for electricity is one of the important things in the advancement of technology and human civilization in all respects. So it is necessary to regulate the use of electrical energy properly. Thus, it is very important for us to regulate the use of electrical energy in terms of power usage by electrical loads. One way is by saving electrical energy. One way to save electrical energy is an energy audit. The audit report is the result of the audit plan which will be processed and analyzed further in energy management (electrical energy regulation). From the results of the energy audit, energy flows will be known which will provide an overview of energy use, so that a strategic plan can be prepared to control energy use better and of course be more energy and cost efficient. One aspect of an energy audit is an audit of lighting energy (lighting in an area), so it is very important for us to control the use of electrical energy loads, in this research the kit only audits electrical energy, from the lighting energy of the Muara Batu sub-district office, North Aceh, so that the use of electrical energy becomes economical. Efficient use of energy can be a solution that will be very profitable in efforts to increase comfort. When an office is able to carry out energy efficiency, it means that the office has benefited from savings in energy consumption costs in a certain period, then from these results there are funds available that can be converted for other needs such as adding facilities or replacing equipment, which will indirectly increase employee comfort or the office.

The utilization of wind energy as one of the renewable energy sources in Indonesia is still limited. This is due to Indonesia's large wind potential, but it is at low speeds. One modification of wind turbines to overcome this problem is by using inverse taper and taper blades. Inverse taper blades have a chord distribution that increases from root to tip while taper blades have a chord distribution that decreases from root to tip. This research conducts the design and construction of inverse taper and taper blades on small-scale wind turbines using NACA 6412 airfoil type, then tested in the field and obtained the performance of each blade. The design was carried out using blade element momentum theory to obtain the blade geometry shape and perform performance analysis of each type of blade. Based on the simulation results obtained from QBlade, it shows that the inverse taper blade performance has a maximum Cp of 0.52 while the taper blade has a maximum Cp of 0.41. The power graph from field testing results shows that inverse taper blades provide good power generation at low wind speeds compared to taper blades. The inverse taper blade has a cut-in speed of 1.2 m/s and the best power production occurs at speeds of 1-4 m/s.
