Abstract

A transformer is a static electric device that is used to change the alternating voltage to a higher or lower level and is used to transfer energy from one electric circuit to another without changing the frequency. When the transformer is working, there is a temperature rise in the transformer which affects the degradation of the insulating paper and transformer oil. This accelerated aging tester applies the drying and vacuuming process as well as the arrangement of paper insulation racks to achieve maximum test results. The research method refers to IEC 60216-3 2006 for aging time, IEC TS 62332-1 2014 and IEC TS 62332-1 2011 as a reference for the Development of Accelerated Aging Experimental Test Cells for Transformer Oil-immersed Paper Insulation Systems. After achieving the existing goals, the addition of the drying process resulted in quite good Breakdown Voltage test results, not only that after the addition of vacuum it produced a good oil color according to ASTM D1500 as well as after the presence of paper placement racks the results of good tensile strength testing were proven by a graph which relatively decreased from sample 1 to sample 3.

Abstract

Photovoltaic is employed to support the national electricity energy blending policy as an additional component of renewable energy. Efficient energy monitoring is utilized to understand the efficiency, energy requirements, and performance of Photovoltaic. This research aims to analyze the performance of a standalone Photovoltaic system. The study considers various parameters such as PV size, load, and charge controller. Additionally, it involves designing a monitoring tool used for the analysis of Photovoltaic performance. Performance measurements are conducted by comparing Photovoltaic systems of different sizes. Furthermore, performance measurements are compared with different types of charge controllers. To assess performance, solar energy is measured at various times using a solar power meter. The solar power meter is then used to analyze the research's performance. Energy monitoring involves measuring voltage, current, power, and energy using Atmega328p. The measurement data is utilized to evaluate system efficiency and design future systems. Monitoring is carried out directly on Photovoltaic systems in the equatorial region. This research measures solar energy, energy produced by Photovoltaic systems, and energy consumed by loads. Energy monitoring focuses on observing solar and Photovoltaic energy during sunlight hours (morning-evening). The analysis results can be utilized for designing efficient Photovoltaic systems in the future..

Abstract

Spodoptera exigua, commonly known as the beet armyworm, is a major pest affecting shallot (Allium ascalonicum L.) plants, leading to significant damage and economic losses for farmers. Traditional pest control methods, such as manual caterpillar removal and pesticide application, have proven ineffective and costly. In response, this study aims to develop an environmentally friendly and sustainable solution by designing a pest control system powered by solar energy, equipped with high-voltage wires, UV lamps, and a raindrop sensor for automatic operation. The system works by converting solar energy into electrical power, which then supplies the pest control unit. The UV lamps attract moths, while the high-voltage wire eliminates them. A raindrop sensor is used to ensure the system operates efficiently by shutting off during rainfall. The method involved discussions with local farmers, design and assembly of the device, followed by field implementation and monitoring in shallot farms. The results show that the device successfully trapped between 40 to 80 moths per day, significantly reducing pest populations and lowering production costs for farmers, as the use of chemical pesticides was minimized. Additionally, the quality of shallot crops improved, leading to higher market value. The solar-powered pest control system is an effective, eco-friendly alternative for managing pest infestations in shallot farming. It offers a cost-efficient solution, reducing the need for pesticides while improving crop quality and yield.

Abstract

The increasing demand for electrical energy, driven by population growth and industrial development, necessitates efficient and sustainable power distribution systems. Transformers, essential components of these systems, typically use mineral oil for insulation and cooling, despite its environmental drawbacks, such as high carbon emissions and non-biodegradability. In response, natural ester oils have emerged as eco-friendly alternatives. This study aimed to compare the dielectric breakdown voltage characteristics of mineral oil (Diala B) and natural ester oil (FR3) in transformer applications. The testing followed the IEC 60156 standard, focusing on transformers operating at 20 kV, with a minimum breakdown voltage threshold of 30 kV/2.5mm. Both treated and untreated samples were examined.The results indicated that FR3 ester oil exhibited superior dielectric properties, including higher breakdown voltage, flashpoint, and firepoint, as well as lower carbon emissions compared to mineral oil. These findings suggest that natural ester oil has significant potential as a sustainable replacement for mineral oil, particularly in applications where environmental and safety concerns are prioritized.The study recommends further long-term testing under operational conditions to confirm the performance and stability of ester oil in real-world transformer applications. These findings contribute to the growing body of research supporting the transition to more environmentally friendly transformer insulation materials, which could have broad implications for the power industry’s sustainability efforts

Abstract

Abstrak – Pemanfaatan energi listrik sebagai upaya menciptakan green energy memerlukan suatu tindakan yang mendukung produksi energi yang efisien dengan menggunakan satu atau lebih energi alternatif yang dapat digabungkan menjadi sumber energi terdistribusi. Permasalahan pokok permintaan sumber energi yang semakin meningkat adalah keandalan sistem dan kualitas daya. Kualitas daya berkaitan dengan pengurangan nilai rugi-rugi daya listrik, berkurangnya nilai jatuh tegangan serta kontinuitas penyaluran energi listrik yang baik. Penambahan distributed generation (DG) pada sistem eksisting dinilai mampu mengurangi permasalahan kualitas daya dan meningkatkan keandalan sistem. Penelitian ini membahas optimasi penempatan DG dengan menggunakan metode Cat Swarm Optimization dan Krill Herd Algorithm. Optimasi dilakukan dengan menginjeksi DG pada sistem eksisting. Dari proses optimasi dengan CSO diperoleh penurunan rugi daya sebesar 0,2 % sedangkan dengan KHA diperoleh penurunan 29,5 %. Perbaikan profil tegangan dengan metode KHA dinilai lebih baik dari CSO dengan nilai diatas 0,99 p.u sedangkan CSO 0,96 p.u. Penelitian ini mengindikasikan bahwa metode KHA lebih baik daripada metode CSO.Kata Kunci — Distributed Generation, Cat Swarm Optimization, Krill Herd Algorithm.
