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.

This research aims to optimize the performance of the voltage system at the Nagan Raya Steam Power Plant (PLTU) by installing capacitor banks. Capacitor banks are integrated into the system to increase voltage stability, reduce power losses, and increase energy efficiency in PLTUs. The research method involves analyzing the existing voltage system, designing the capacitor bank installation, and evaluating the system performance after installation. It is hoped that the results of this research can make a positive contribution in improving the performance of PLTU Nagan Raya and overall energy efficiency.

Utilization of solar energy as a generator of electrical energy is growing. One of technology for the use of solar energy is to use solar panels to generate electricity. Solar panels can be installed on the roof of the house to meet electricity on a household scale. The current challenge is the lack of trained personnel who have the competence to install solar panels on the roof of the house. So it is considered it is important to educate skilled workers through solar power installation training. For this purpose, training activities for solar electricity installation are carried out for Dayah Mini Banda Aceh students through an independent community service program. This training aims to train workers to gain Panel installation competence Sun on the Roof of the House. Solar Panel Installation Practice Method is done by simulating installation of equipment ranging from solar panels, inverters, charge controllers and charging battery. The results to be achieved with the practice of installing solar panels so that students have Skills in installing rooftop solar panels.

Electricity is very useful for human life. However, if an error in use results in a danger to the safety of humans, livestock and property. Sometimes electricity is also used for special purposes for which there are no guidelines, this will be very risky to safety. As in the case that occurred recently in the Pidie Resort Police area, the Head of the Pidie Resort Police assigned his members for the benefit of the police service in the context of the task of carrying out an examination of electrical experts to obtain information regarding the discovery of a body in the mountain river of Gampong Lhok Broh, Meureudu District, District Pidie Jaya. The expected objectives of this activity are; So that participants can understand the benefits of electrical energy and the basic principles, operation, and maintenance of electrical equipment, Provide participants with knowledge (in general) about how to work and maintain electrical equipment that may be designed and used in a community environment, Demonstrate directly the dangers of some related electrical equipment cases currently being handled by the police. This activity was carried out from October 1 to November 30 2019 and consisted of 3 stages namely; Preparation, Execution, and Compilation of Reports. Based on inspections and field trials in two places, the following conclusions can be drawn; Electric current is dangerous for the human body depending on the amount of current and duration. The effect of electric current on humans starts with tingling/numbness to effect the heart which can cause death. Water is a conductor that can carry electric current properly. The safe voltage limit for humans is 50 Volt AC assuming the human body is 1000 Ohm resistant, the safe current limit for humans is 30 mA. The dedicated team also as electrical experts discusses scientific about matters related to electrical hazards and their effects on the human body.

Solar energy is a renewable energy source that has become increasingly popular in recent years as an electricity source. However, the availability of trained personnel to install rooftop solar panels is limited. This community service program was conducted to provide training in residential solar system installation for students from Dayah Mini Banda Aceh. The training took place in the Power Electronics and Renewable Energy Laboratory at Universitas Syiah Kuala, where theoretical training on renewable energy was combined with demonstrations of equipment and simulated installation practice. The modules included rail mounting, panel positioning, inverter connections, charge controller setup, and wiring in series and parallel. Students were guided by lecturers and assisted by engineering students who had already undergone training in this field. They exhibited great enthusiasm and completed all the stages of installation successfully. This program not only addresses the shortage of workers with such skills in the solar installation industry but also helps students from low-income families acquire these practical competencies that can lead to jobs or entrepreneurship within the ever-growing sector of renewable energy; thus reducing unemployment among their communities while supporting Indonesia's shift towards sustainable energy.

Maximum photovoltaic power point (MPVPP) based on DC-DC buck converter is supplied by photovoltaic module. A controller method is needed to control the signal that it drives the switching component of DC-DC buck converter. The previous researcher conducts proportional integral derivative (PID) controller applying the DC-DC buck converter, but only its parameters (proportional, KP, integral, KI, and derivative, KD) are studied. This paper presents MPVPP based on PID with gain (PIDG) controller on the DC-DC buck converter by tuning the parameters of KP. KI and KD and adding a gain, G connected to PIDG controller for charging 12 V, 7 Ah battery. The DC-DC buck converter is designed for the output voltage of 14.7 V and output power of 150 W and modelled using Simulink MATLAB. The simulation results show that the parameters of KP=0.0032, KI=1, and KD=4×10-7 are suitable to control the switching component. The gain, G gives significant effect on the settling time and the time to reach their steady state value of output voltage of 14.7 V. The battery SOC can increase 1.36% per second, if the initial SOC is 25%, thus it needs arround 55 seconds to reach the fully charging condition.
