Abstract

The transition to renewable energy is increasingly important in addressing global energy demands and environmental issues. Solar energy has emerged as a sustainable option, particularly for small and micro businesses that often face challenges related to energy supply and costs. Shashi Baby and Kids Food, a micro – enterprise producing baby food, can benefit from an off – grid solar power system to support its operational needs, especially lighting during the night. The system design involves analyzing energy requirements, selecting solar panels, batteries, inverters, and simulating the system using PVsyst software to optimize performance. This system is designed to support operations with nine lamps for 12 hours a day, generating sufficient energy and ensuring adequate storage. Simulation results show that the system has a performance ratio (PR) of 75.86% and a solar fraction (SF) of 99.82%, indicating high efficiency and nearly fully meeting energy needs through solar power. Although there is a slight decrease in SF in December, this system design has proven to be efficient and reliable in supporting business operations. Further analysis reveals that the annual energy production reaches 1451 kWh, with specific production of 1210 kWh per kWp, confirming that this system can generate significant energy for the operational needs of the business.

Abstract

Pemahaman dan kesadaran tentang pentingnya renewable energy harus ditanamkan sejak dini melalui Pendidikan formal. Sekolah Menengah Kejuruan (SMK), sebagai institusi Pendidikan vokasi memiliki peran strategis dalam menghasilkan lulusan yang siap kerja. SMK N 2 Solok merupakan salah satu sekolah menengah kejuruan yang memiliki potensi besar dalam mengintegrasikan konsep renewable energy. SMK N 2 Solok dipilih sebagai lokasi kegiatan karena memiliki jurusan Teknik Instalasi Tenaga Listrik yang relevan dengan pengembangan teknologi energi terbarukan serta didukung oleh fasilitas laboratorium yang memadai. Pelaksanaan program pengabdian masyarakat di SMKN 2 Solok berfokus pada peningkatan pemahaman siswa dan guru terhadap renewable energy. Dengan metode sosialisasi bentuk ceramah yang meliputi presentasi materi dan permainan simulasi integrasi renewable energy kedalam existing grid. Hasil evaluasi menyatakan bahwa, dari 25 responden, dimana 92% adalah siswa, 44% menyatakan sangat sesuai dan 48% diantaranya menyatakan sesuai topik dan materi sosialisasi dengan kebutuhan mitra.

Abstract

The alignment process using the laser method is one of the alignment techniques that can be applied to address misalignment. The laser method operates by utilizing an infrared laser sensor to perform the alignment between the driving object, in this case the induction motor, and the driven object, namely the spray washing pump. The alignment process aims to align the shaft of the driving object (the induction motor) with the shaft of the driven object (the spray washing pump), ensuring that both shafts are properly aligned. Misalignment refers to a condition in which there is a lack of alignment between the driving shaft and the driven shaft.
Technical Performance Analysis of a 1 MWp Grid-Connected Photovoltaic System in Pangkalan Kerinci, Indonesia Using PVsyst Simulation Laksono, Dedi Tri; Laksono, Deni Tri; Fahmi, Monika Faswia; Afrianti, Rien; Dodi, Nofri

Abstract

The increasing demand for clean energy in Indonesia has accelerated the deployment of grid-connected photovoltaic (PV) systems. This study presents a technical performance analysis of a 1 MWp grid-connected PV system located in Pangkalan Kerinci, Indonesia, using the PVsyst v7.4.6 simulation software. The system comprises 1818 Trina Solar TSM-DE19-550Wp modules mounted on a fixed-tilt structure (2.2° tilt, 180° azimuth) with two SMA Sunny Central 400 MV-11 inverters (DC/AC ratio = 1.25). Meteorological data from Meteonorm 8.1 (1996–2015) was used to simulate annual irradiation and system output. The results show an annual energy production of 1,404,124 kWh, corresponding to a specific yield of 1,404 kWh/kWp/year. The Performance Ratio (PR) reached 82.75%, indicating high system efficiency under tropical climatic conditions. Loss analysis revealed that thermal losses (9.36%) and IAM losses (2.58%) were the dominant factors, while inverter losses accounted for 2.86%. Module mismatch and wiring losses were minimal at 2.15% and 1.5%, respectively. The high PR and low degradation assumptions confirm the suitability of the selected configuration for equatorial regions. This study provides a robust technical benchmark for similar PV installations in Sumatra and supports optimal design decisions for future utility-scale solar projects in Indonesia.
