Abstract

Perubahan iklim akibat pemanasan global menuntut penggunaan teknologi pembangkit listrik yang ramah lingkungan. Pembangkit Listrik Tenaga Surya (PLTS) merupakan salah satu pembangkit yang ramah lingkungan. Namun, pembangkit ini bersifat intermiten sehingga jika dioperasikan secara off-grid akan memerlukan perangkat penyimpanan energi. Paper ini merancang suatu sistem PV off-grid pada daerah 3T (tertinggal, terdepan, dan terluar) di Indonesia dengan menggunakan sistem penyimpan energi hibrida, yaitu baterai dan superkapasitor. Fluktuasi energi jangka pendek diutamakan ditangani oleh superkapasitor, sedangkan energi jangka panjang yang lebih stabil disuplai oleh baterai. Pendekatan ini bertujuan mengurangi stres dan siklus charge-discharge baterai, sehingga memperlambat degradasi baterai. Performa dari sistem ini diuji dengan melakukan pemodelan dan simulasi aliran energi pada MATLAB. Berdasarkan hasil simulasi, dilakukan prediksi umur baterai dengan menggunakan algoritma rain flow counting dan perhitungan Levelized Cost of Energy (LCOE) dari sistem pembangkit. Hasil penelitian menunjukkan bahwa penambahan superkapasitor pada sistem penyimpanan energi dapat menstabilkan transien daya dan mengurangi siklus charge-discharge baterai, sehingga memperpanjang umur baterai . Selain itu, LCOE pada sistem dengan superkapasitor lebih rendah daripada sistem tanpa superkapasitor.

Abstract

Photovoltaic (PV) systems are a promising renewable energy source due to their ease of installation, eco-friendliness, and abundant solar radiation availability. Indonesia has a theoretical potential of 4.625 kWh/m² and a practical potential of 3.767 kWh/kWp; however, as of September 2021, its installed capacity was only 194 MW. Land constraints have led to the development of floating PV systems, which reduce land usage and enhance module efficiency due to lower temperatures above water. Nonetheless, PV systems face challenges from solar radiation intermittency, influenced by cloud opacity, causing output power fluctuations. This study maps cloud opacity patterns on Kodingareng Island based on dry and rainy seasons using 2020 BMKG data. Results indicate that output power during the dry season is more stable than in the rainy season due to lower cloud cover. Conversely, thick cloud cover during the rainy season reduces solar radiation reaching PV modules, resulting in fluctuating power output. Thus, floating PV systems demonstrate better energy availability during the dry season. This study highlights the importance of understanding cloud opacity patterns in planning floating PV systems to address the challenges of solar radiation intermittency.

Abstract

Indonesia, as an archipelagic country with over 17,000 islands, faces significant challenges in providing electricity access, particularly to small and remote islands. One promising solution is Solar Power Plants (PLTS), both land-based and floating solar plants that utilize water surfaces, suitable for areas with limited land availability. This study evaluates the economic feasibility of floating solar plants and land-based solar plants using the Levelized Cost of Electricity (LCoE) approach. LCoE encompasses all costs of construction, operation, maintenance, and energy production over the plant's lifespan, serving as a key benchmark in selecting power generation technologies. The findings show that the LCoE for floating solar plants is Rp11,197.00/kWh, lower than land-based solar plants at Rp11,769.00/kWh, although both exceed the electricity purchase price in Kodingareng, South Sulawesi, at Rp2,460.00/kWh. This difference is influenced by higher construction costs for floating solar plants but offset by greater energy output and lower operation and maintenance costs. This research provides a basis for developing solar power systems in archipelagic regions, emphasizing efficiency and sustainable energy solutions.

Abstract

 This Community Service Program aims to enhance the production capacity of red bricks at UMKM Putra Mandiri, located in Mulyadadi Village, Cipari District, Cilacap Regency, through the implementation of a red brick extruder machine. The partner’s main issue was the manual production process, which limited production capacity and resulted in inconsistent brick quality. The program activities included field observations, partner discussions, training sessions, and mentoring on machine operation and maintenance. The results showed that using the extruder machine significantly increased production capacity from 100 pcs/hour to 750 pcs/hour, indicating a 750% improvement compared to manual methods. Furthermore, the  produced bricks demonstrated better uniformity, density, and strength, while reducing production time and labor intensity. The adoption of this appropriate technology not only improved productivity and competitiveness but also strengthened the partner’s independence in business operations. The implication of this activity is that technological transfer through community service programs can provide sustainable impacts on local economic development by promoting innovation, efficiency, and self-reliance among small enterprises.
