Abstract

As the needs of human life increase, the need for electrical energy will also increase. Currently, fossil energy, which is widely used as fuel for the provision of electrical energy, is running low. In Indonesia, renewable energy sources have not been utilized properly, such as wave energy. This study discussed how to design a prototype of a sea wave power plant. The problem is, how to be able to utilize the energy of sea waves to the maximum. The purpose of this research is to find solutions and designs to utilize recoil starter as a prototype of ocean wave power plants. The methodology used in this study is an experiment in which the prototype made is given a certain treatment and then measurements are made. His data analysis technique is descriptive analysis. Based on the results of measurements and observations, the performance of the tool is not only influenced by the height of the wave, but also the period of arrival of the sea wave and the ballast load of the tool. After measurements were made on the first day of Maruni beach, the prototype could produce an average power of 4.21 watts for an average wave height of 0.35 cm and Maruni beach on the second day could produce an average power of 5.68 watts for an average wave height of 0.4 m. While on the first day Amban beach obtained an average power of 3.29 watts for an average wave height of 0.37 cm and Amban beach on the second day could produce an average power of 14.26 watts for an average wave height of 0.5 m.

Abstract

The interconnection of renewable energies increases the complexity of modern power systems. Hence, stability assessments should be made to ensure the system’s stability after penetration. Solar power is a type of renewable energy that has become a widespread energy source among renewable energy sources. About 1 MWp of the solar power plant has been prepared to be interconnected to the IEEE 8 bus of Manokwari grid, and this paper investigates the voltage profile, power losses, and stability of the solar power plant penetration using an adaptive kernel density estimator (AKDE) and compares it to a Monte Carlo simulation (MCS)-based probabilistic load flow (PLF). About 5000 samples have been used to test the grid after the connection. Results of simulations show that the solar penetration can reduce power losses from 0.4084 MW to 0.3080 MW and 0.3045 MW by the proposed method and MCS method, respectively, and further increase the bus voltage profile. The power network has the stability to be connected to solar power, as indicated by the small stability index values of each bus. The proposed method using the AKDE method has a more accurate result in stability indices indicated by small fast voltage stability index (FVSI), line stability index (Lmn), and line stability factor (LQP) indices.

Abstract

ABSTRACT  The Community Service Program (PkM) is an annual initiative consistently conducted by the Faculty of Engineering at the University of Papua. In 2025, the program was carried out in Kampung Kwau, Warmare District, Manokwari Regency, West Papua Province, with the primary objective of enhancing local community understanding and skills in utilizing renewable energy, particularly through the use of energy-efficient solar lamps (LTSHE). The program began with presentations on the potential and benefits of renewable energy, followed by hands-on training in the maintenance and repair of LTSHE units. During the practical sessions, participants were introduced to techniques for replacing damaged batteries, cleaning solar panels, and understanding the basic operational system of the LTSHE devices. Despite challenges such as limited tools and varying levels of participant knowledge, the activity was met with enthusiastic responses. This program is expected to promote the sustainable use of environmentally friendly energy in Kampung Kwau.  Keywords: Renewable Energy; Kampung Kwau; LTSHE; Community Service; Solar Power.   ABSTRAK  Pengabdian kepada masyarakat (PkM) merupakan program tahunan yang secara konsisten dilaksanakan oleh Fakultas Teknik Universitas Papua. Pada tahun 2025, kegiatan ini berlokasi di Kampung Kwau, Distrik Warmare, Kabupaten Manokwari, Provinsi Papua Barat, dengan tujuan utama meningkatkan pemahaman dan keterampilan masyarakat dalam pemanfaatan energi terbarukan, khususnya melalui penggunaan lampu tenaga surya hemat energi (LTSHE). Rangkaian kegiatan diawali dengan penyampaian materi mengenai potensi dan manfaat energi terbarukan, kemudian dilanjutkan dengan pelatihan praktik pemeliharaan dan perbaikan LTSHE. Dalam sesi praktik, peserta diperkenalkan pada teknik penggantian baterai yang rusak, pembersihan panel surya, serta pemahaman dasar mengenai sistem kerja perangkat LTSHE. Meskipun terdapat kendala seperti keterbatasan alat dan variasi tingkat pemahaman peserta, kegiatan ini mendapat sambutan yang sangat positif. Program ini diharapkan dapat mendorong pemanfaatan energi ramah lingkungan secara berkelanjutan di Kampung Kwau dan menjadi model yang dapat direplikasi di wilayah lain.

Abstract

The level of reliability determines the continuity of electricity distribution in the power system, the availability of insufficient power will affect the level of reliability of the system. The Loss of Load Probability (LOLP) method is a popular method to calculate the reliability of an electric power system. A high level of reliability is obtained with a small level of risk. The value of the disturbance in the generating units, or the forced outage rate (FOR), is calculated using the installed power data and the disturbance data of each unit. The probability of each generating unit, the probability when another generating unit is added, and the cumulative probability can be calculated based on the FOR value. From the intersection point of the interval of the load curve in one year, the intersection is reached on the 346th day with 720 kW, which is the force outage limit. The results of the LOLP calculations show that the electric power system at PT. PLN Rayon (Persero) Fakfak has experienced a forced outage for about 90.5828 days per year.

Abstract

The quality of electricity includes several things, including continuity of distribution, length of blackout time, voltage stability. One of the causes of declining electricity quality is the shrinkage that occurs in the electric power network, network losses cannot be avoided but can be minimized by shortening the network, performing maintenance and maneuvering the load. Energy losses in the electrical system come from the power generation, transmission and distribution system. In the transmission system, energy losses can be minimized by increasing the transmission voltage to high and extra high voltage levels. The load curve is a curve in a time range which shows the value of electrical energy use and load for a feeder so that PT. PLN (Persero) UP3 Manokwari can estimate power requirements. Expense curves can be divided into three types, namely daily curves, monthly curves and annual curves. Research throughout October 2021 used quantitative methods in processing data and calculating losses so that the power loss was 2.0070% and the energy loss was 1.9847%. This loss is still far below the state electricity company standard D3.002-2 (2008) in range of 5% to 10%.
