Abstract

The Maluku region, also known as the Moluccas, is an archipelago in Indonesia with exceptional wind patterns ideal for wind power generation. Its strategic location between the Pacific and Indian Oceans creates strong and consistent winds due to temperature differences, making it an optimal site for wind energy production. Harnessing wind power in Maluku can significantly benefit Indonesia and the global renewable energy sector by providing a reliable and sustainable energy source to reduce greenhouse gas emissions and combat climate change. Furthermore, the development of wind power in Maluku could create new economic opportunities and incentives for the local community, promoting sustainable development and reducing the reliance on fossil fuels. A study was conducted to assess the viability of wind energy in Maluku, utilizing a Sonius turbine and computational fluid dynamics (CFD) methodology. By varying the center distance between the Savonius blade radius and its rotational axis, researchers aimed to optimize the turbine's design for maximum energy extraction. The simulations showed that turbine model design significantly impacts performance, with Model 2 outperforming Model 1 due to smoother airflow and more efficient rotation. The pressure distribution on the semicircular blades also influenced turbine performance, with Model 1 producing higher force but slower rotation speed compared to Model 2. The simulations showed that Turbine Model 1 produced a higher average force and power output compared to Turbine Model 2. According to the simulations, Model 1 showcased a higher average power output of 66.5 Watts, while Turbine Model 2 only achieved 46.6 Watts. However, Turbine Model 1 had a slower rotation speed due to its larger radius. Under consistent wind conditions, Turbine Model 1 was capable of producing 5.5% more energy than Turbine Model 2. Choosing an efficient turbine model is crucial for maximising the energy production from wind resources. The findings from this study contribute to a comprehensive understanding of the turbine's behavior and can aid in optimizing its design for maximum energy extraction.

Abstract

Kebutuhan akan sumber energi yang andal dan fleksibel semakin penting, terutama di daerah terpencil dan situasi darurat yang sulit dijangkau oleh jaringan listrik konvensional. Salah satu solusi yang dikembangkan adalah sistem pembangkit listrik hybrid yang menggabungkan sumber energi terbarukan berbasis energi surya dan konvensional. Penelitian ini bertujuan untuk menganalisis performa sistem hybrid Pembangkit Listrik Tenaga Surya (PLTS) dan PLN dalam pengisian serta pengosongan baterai pada sistem power station mobile sebagai solusi mobilitas energi mandiri. Pengujian dilakukan dengan dua metode pengisian yaitu menggunakan modul surya dan listrik PLN, serta dua skenario pengosongan dengan menggunakan beban pompa air dan lampu LED. Hasil menunjukkan bahwa pengisian dengan modul surya selama 7 jam 15 menit mampu meningkatkan tegangan baterai dari 11,9 V hingga 12,52 V dengan energi maksimal 1.252 Wh, menunjukkan efisiensi tinggi saat radiasi matahari optimal. Sementara itu, pengisian menggunakan listrik PLN selama 11 jam 30 menit menunjukkan kestabilan tinggi, dengan tegangan meningkat hingga 12,97 V dan energi mencapai 1.297 Wh. Pengosongan baterai menggunakan pompa air berlangsung selama 2,5 jam dengan penurunan tegangan hingga 10,77 V dan arus mencapai 22,8 A, sedangkan pengosongan dengan lampu LED selama 4 jam 45 menit menunjukkan penurunan tegangan hingga 10,91 V dengan arus stabil sekitar 13 A. Hasil ini menunjukkan bahwa sistem hybrid mampu menyediakan dan menyimpan energi secara efisien serta menunjang kebutuhan daya beban secara konsisten. Sistem ini potensial untuk diimplementasikan di daerah terpencil dan kondisi darurat yang memerlukan sumber energi mandiri.
