Abstract

Indonesia has enormous solar energy potential, but local climate variability often causes deviations between design estimates and actual performance. This study aims to analyze the effect of climate parameters on the performance of a 1 kWp solar power system in six different climate zones through PVsyst simulation. The results show significant variations in annual energy production, with the highest values in Makassar (1,453 kWh/kWp) and Ternate (1,452 kWh/kWp), while the lowest is in Jakarta (1,293 kWh/kWp). This difference is triggered by the diffuse radiation (DIF) ratio, which reaches 1,001.4 kWh/m² in Jakarta due to pollution and high cloud cover, which reduces the Performance Ratio (PR) to an average of 76%. This study concludes that microclimate factors, particularly the DNI/DIF ratio, are more decisive for system efficiency than daily average radiation alone.

Abstract

Indonesian waters have intense shipping and offshore oil industry activities, often resulting in marine pollution from oil spills. These spills damage marine ecosystems, disrupt sea transportation, cause organism mortality and migration, and reduce fishery production as well as marine tourism. To mitigate oil pollution, oil skimmers are widely used. However, their current applications mostly rely on generator-based electric power and are limited to land-based industrial environments. This study aims to develop a floating oil skimmer powered by renewable energy for marine oil spill recovery, utilizing the abundant solar and wind resources available at sea. The research employs a design-based approach combined with model testing to enhance the accuracy of calculation inputs. The results indicate that the barge-type platform provides optimal performance due to its high buoyancy, low resistance, and good stability and seakeeping characteristics. The oil skimmer integrates a corrugated plate interceptor (CPI) separator to accelerate the oil–water separation process. Two 100 Wp solar panels supply electrical power stored in two 12 V, 32 Ah hybrid batteries, which operate an oily water pump, a DC 775 motor for the skimmer drum, and a cooling system pump to prevent component overheating. Experimental results show the highest efficiency at 120 RPM, with an average oil recovery rate of 2.2 mL per revolution, equivalent to 15.84 L/h or 380.16 L/day. Further improvements are recommended by optimizing the skimmer material, adjusting its position, refining the oil scraper, and adding an oil skimmer unit in Chamber 1.

Abstract

With an emphasis on Indonesia's solar energy potential, this study investigates how panel tilt angle affects energy efficiency in solar power-producing systems. Economic expansion is increasing the energy demand, which is driving a search for affordable, sustainable, and ecologically friendly renewable energy sources. Because solar power plants use sunlight to generate energy, it is crucial to design systems considering variations in sunshine intensity brought on by elements such as solar panel tilt angle. This experiment shows that adjusting the tilt angle can maximize solar energy absorption and increase conversion efficiency. By collecting meteorological data from a representative site in Makassar and conducting experiments with tilt degrees ranging from 0° to 60°, a dogmatic approach was taken. According to the results, an ideal tilt angle of 10° produces the most energy output each year, however angles between 30° and 40° work best from May to August when sunlight is at its strongest. The results show that to optimize solar energy efficiency and encourage the use of renewable energy, tilt angle modifications must be made appropriately based on seasonal variations.Keywords – Efficiency, Renewable Energy, Solar Power, Tilt Angle.

Abstract

Pemanfaatan teknologi dalam pendidikan dasar menjadi semakin krusial di tengah perkembangan era digital dan Revolusi Industri 4.0. Kegiatan pengabdian ini dilatarbelakangi oleh pentingnya peningkatan literasi teknologi di lingkungan sekolah dasar, khususnya dalam pemanfaatan kecerdasan buatan (Artificial Intelligence/AI) untuk mendukung proses belajar mengajar yang lebih interaktif dan adaptif. Program ini dilaksanakan di UPT SD Negeri 16 Parepare dengan tujuan utama untuk mengimplementasikan pendekatan pembelajaran berbasis AI. Metode pelaksanaan meliputi pelatihan intensif kepada guru mengenai konsep dan praktik penggunaan AI, penerapan langsung AI dalam kegiatan pembelajaran di kelas, serta evaluasi untuk mengukur dampak kegiatan. Hasil kegiatan menunjukkan adanya peningkatan pemahaman dan keterampilan guru dalam mengintegrasikan AI ke dalam pembelajaran, serta meningkatnya minat dan partisipasi aktif siswa selama proses belajar. Kegiatan ini memberikan kontribusi positif dalam memperkenalkan transformasi digital di lingkungan sekolah dasar, serta berpotensi menjadi model replikasi untuk sekolah lainnya.
