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

Background : This study investigates the technical and economic feasibility of an on-grid rooftop solar photovoltaic (PV) system for the Postgraduate Building of the University of Papua, West Papua, Indonesia. Amid rising energy demands and limited renewable energy utilization in the region, this research addresses the need for sustainable electricity solutions. Methods: The system was designed using Helioscope software, considering solar radiation, shading, and local climate data. The proposed configuration consists of 14 polycrystalline solar modules (320 Wp each) and one SMA Sunny Tripower 5.0 kW inverter. Results: Simulation results indicate that the system can produce approximately 5,660 kWh annually, covering 19% of the building’s electricity consumption. The estimated initial investment of Rp 137,200,000 yields annual savings of Rp 9,617,740, resulting in a payback period of 14 years and 2 months. Conclusion: The findings demonstrate the viability of rooftop solar power systems for reducing energy costs and enhancing sustainability in remote areas. The project serves as a replicable model for academic institutions seeking to adopt renewable energy technologies. Novelty: This study provides a localized case of solar PV deployment in West Papua, contributing empirical insights to regions with limited renewable energy integration and offering a practical approach to energy transition in underserved areas.

Abstract

Kebutuhan akan listrik telah menjadi salah satu hal penting bagi masyarakat saat ini. Lebih dari 88% dari sumber energi listrik berasal dari bahan bakar fosil. Pemanfaatan sumber energi yang tidak dapat diperbarui menyebabkan konsekuensi buruk bagi lingkungan. Untuk menanggulangi masalah tersebut serta mengurangi beban listrik PLN yang meningkat, penting untuk mengembangkan teknologi energi terbarukan yang bersifat ramah lingkungan. Memanfaatkan energi matahari melalui pembangunan pembangkit listrik tenaga surya (PLTS) adalah langkah yang sesuai untuk memenuhi kebutuhan pokok akan listrik. Balai Kampung Wamfoura memiliki luas atap yang cukup besar dan memiliki potensi iradiasi/intensitas sinar matahari sebesar 4,648 kWh/m2/day menurut data Global Solar Atlas. Kampung Wamfoura memiliki masalah yaitu hanya teraliri listrik PLN dari pukul 6 sore hingga pukul 6 pagi. Untuk mengatasi masalah tersebut dilakukan penelitian ini untuk merencanakan PLTS off-grid pada Gedung Balai Kampung Wamfoura. Untuk memenuhi konsumsi listrik harian Balai Kampung Wamfoura yaitu sebesar 9,952 kWh/hari dibutuhkan 14 panel surya dengan kapasitas 380 Wp, 24 buah baterai dengan kapasitas 296 Ah, dan 2 inverter dengan kapasitas 4000 W. Simulasi PVSyst menghasilkan 3632.5 kWh per tahun dengan performance ratio 35%. Dengan hasil produksi energi listrik tersebut maka dapat memenuhi konsumsi listrik harian Balai Kampung Wamfoura.
