https://doi.org/10.62391/ejmi.v8i1.202Krisis energi dan tingginya ketergantungan terhadap generator set (genset) diesel pada sektor budi daya tambak udang telah mendorong urgensi pemanfaatan energi terbarukan sebagai solusi yang berkelanjutan. Penelitian ini bertujuan untuk mengevaluasi kinerja teknis dan kelayakan ekonomi dari implementasi sistem Pembangkit Listrik Tenaga Surya (PLTS) off-grid berkapasitas 480 Wp guna memenuhi kebutuhan energi pompa aksial di Desa Bumi Dipasena Sentosa, Provinsi Lampung. Metode penelitian menggunakan pendekatan kuantitatif melalui pemodelan dan simulasi komputasi dengan perangkat lunak HOMER Pro. Parameter simulasi didasarkan pada data radiasi matahari, temperatur lingkungan presisi, serta profil beban harian operasional sebesar 1,6 kWh. Hasil simulasi menunjukkan bahwa sistem PLTS mampu memproduksi energi sebesar 678 kWh/tahun dengan capacity factor sebesar 16,1% dan fraksi energi terbarukan (renewable fraction) mencapai 100%. Selain itu, simulasi mengonfirmasi ketiadaan beban yang tidak terpenuhi (unmet load) maupun kekurangan kapasitas (capacity shortage). Dari aspek ekonomi, nilai Levelized Cost of Energy (LCOE) tercatat sebesar Rp274/kWh, yang mengindikasikan bahwa sistem ini sangat ekonomis dan kompetitif jika dikomparasikan dengan sumber energi fosil konvensional. Analisis struktur biaya juga mengungkapkan bahwa komponen baterai merupakan penyumbang proporsi terbesar, yakni mencapai 77,15% dari total biaya sistem. Secara keseluruhan, perancangan sistem PLTS off-grid 480 Wp ini dinyatakan sangat layak baik secara teknis maupun ekonomis, serta berpotensi menjadi solusi energi bersih yang andal untuk mendukung keberlanjutan operasional tambak udang di kawasan terpencil.
The energy crisis and the high dependency on diesel generator sets within the shrimp farming sector have driven the urgency of utilizing renewable energy as a sustainable solution. This study aims to evaluate the technical performance and economic feasibility of implementing a 480 Wp off-grid Solar Power Plant (PLTS) system to meet the energy demands of an axial pump in Bumi Dipasena Sentosa Village, Lampung Province. The research methodology employs a quantitative approach through computational modeling and simulation using the HOMER Pro software. The simulation parameters consider solar radiation data, ambient temperature, and a daily operational load profile of 1.6 kWh. The simulation results reveal that the system is capable of generating 678 kWh/year of energy with a capacity factor of 16.1% and a renewable energy fraction reaching 100%. Furthermore, the simulation confirms the absence of both unmet load and capacity shortage. From an economic perspective, the Levelized Cost of Energy (LCOE) is recorded at Rp274/kWh, indicating that the system is highly economical and competitive compared to conventional fossil energy sources. Cost structure analysis also highlights that the battery component constitutes the largest proportion, accounting for 77.15% of the total system cost. Overall, the design of the 480 Wp off-grid solar power system is proven to be highly feasible, both technically and economically, establishing it as a reliable clean energy solution to support the sustainability of shrimp farming operations in remote areas.
