Abstract

Solar energy is a renewable energy source that can be converted into electrical energy through photovoltaic (PV) solar cells. However, the efficiency is low, with only 15-20% depending on solar irradiation converted into electricity. The angle of the sun and the structural position of the solar cell system also affect the amount of solar radiation received. Research has been carried out to determine the effect of radiation intensity on the performance of PV solar cells using experimental methods and thermal simulation. The temperature distribution of PV cells has been studied using experimental studies and thermal simulations. The highest temperature was produced at a solar radiation intensity of 1100 W/m2 of 68.4 ⸰C for the experimental study and 69.4 ⸰C for the thermal simulation study. The highest efficiency is produced at a radiation intensity of 1000 W/m2, with the highest efficiency being 11.5%. This study analyzes the impact of radiation intensity on the electrical efficiency of solar PV cells using two-way ANOVA. The radiation intensity has a P-value of 1.85E-05, which indicates an influence on the electricity produced. There is an MS value of research variation smaller than the MS error of 7.22E-07, indicating an interaction between the two variables

Abstract

Kelompok Tani Dukuh (POKTAN) Mekarsari mendirikan Taman Mekarsari di Desa Kaligentong, Boyolali yang dulunya merupakan tempat pembuangan sampah. Mekarsari telah diubah menjadi tujuan wisata dengan tiga tujuan utama. Pertama adalah untuk menjaga sungai dan ekologinya, termasuk flora dan satwa liarnya, sehingga dapat terus menjadi tumpuan kehidupan pedesaan. Tujuan kedua adalah sebagai tempat hiburan warga, pendidikan sains dan alam, serta pengembangan seni dan budaya daerah. Sedangkan tujuan terakhir adalah merevitalisasi ekonomi lokal dengan menyelenggarakan pasar rakyat di kawasan wisata. Permasalahan yang dihadapi masyarakat khususnya kelompok tani terutama yang terlibat langsung dalam pengelolaan Taman Wisata Mekarsari adalah tidak adanya lahan kosong untuk anak-anak bermain dan belajar. Taman bermain prasekolah membantu anak-anak bergerak dan bermain. Bermain di taman bermain dapat memberikan banyak manfaat perkembangan bagi anak, antara lain belajar dan melatih keterampilan sejak usia dini. Saat merencanakan taman bermain anak-anak, seseorang harus mempertimbangkan aspek berwujud dan tidak berwujud. Banyak taman bermain prasekolah yang telah dibuat selama ini, namun kebanyakan berfokus pada faktor keamanan daripada manfaat perkembangan bagi anak. Pengabdian ini dilaksanakan pada taman Mekarsari dengan pembuatan wahana taman bermain berupa ayunan jungkat jungkit. Malalui wahana ini diharapkan dapat meningkatkan kepercayaan diri dan keberanian untuk menghadapi suatu hal yang baru. Koordinasi dan keseimbangan lagi-lagi dibutuhkan saat bermain jungkat-jungkit. Tak hanya itu dengan bermain permainan ini anak-anak juga belajar saling bekerja sama satu sama lain.

Abstract

Energy sustainability is crucial for mitigating climate change and reducing dependence on fossil fuels. This research evaluates a hybrid renewable energy system combining photovoltaic (PV) technology and wind turbines to meet the electricity demand of Wahid Hasyim University's Faculty of Engineering, totalling 555,000 VA. Using HOMER Pro software, the study identifies the optimal configuration based on technical, economic, and environmental aspects. The hybrid system integrating PV, wind turbines, batteries, and converters achieves the lowest Net Present Cost (NPC) of $214,877 and a Levelized Cost of Energy (LCOE) of $0.0185/kWh, outperforming grid-only systems. Environmentally, the system significantly reduces carbon dioxide (CO2) emissions, from 559,226 kg/yr in conventional systems to 62,452 kg/yr. Solar energy contributes 56% of electricity generation, leveraging stable solar radiation of 4.28–5.54 kWh/m²/day. Additionally, an annual surplus of 156,350 kWh can be sold back to the grid, enhancing operational efficiency. This study demonstrates that hybrid renewable energy systems deliver long-term cost efficiency and significantly mitigate climate impacts. It provides a sustainable energy model for campuses in Indonesia and worldwide, particularly in regions with abundant solar resources.

Abstract

The increasing energy demand and environmental challenges have accelerated the global shift toward renewable energy, with Indonesia possessing a substantial solar potential of 3,294 GW. This study investigates the techno-economic feasibility of a 40.9 kWp On-Grid Solar Power Plant  as a supplementary energy source to reduce operational costs at the Tulungagung Hydropower Plant. A techno-economic analysis was conducted using 2024 solar PV production data from the ShinePhone application and the Tulungagung Hydropower business daily report, complemented by simulations from the Hybrid Optimization Model for Multiple Energy Resources (HOMER) to identify optimal system configurations. The actual solar power plant generated 52,499.9 kWh/year, contributing 15.66% of the plant's operational load of 335,150.71 kWh and resulting in annual cost savings of IDR 58,523,260, based on a PLN tariff of IDR 1,114.74/kWh. In comparison, HOMER simulations projected a higher generation of 74,265 kWh/year, with a net present cost (NPC) of IDR 6,461,879,000 and a cost of energy (COE) of IDR 1,142.36. While the PLTS has proven technically and economically viable as a complementary energy source, its current capacity remains insufficient to fully meet the hydropower plant's operational load, indicating the need for further system optimization and potential integration of energy storage solutions.
