Abstract
Kebutuhan energi listrik yang terus meningkat di Indonesia belum sepenuhnya diimbangi dengan pemerataan pasokan, terutama di wilayah kepulauan dan daerah terpencil. Salah satu contoh nyata adalah Pulau Gili Raja di Kabupaten Sumenep, Jawa Timur, yang hingga kini masih bergantung pada Pembangkit Listrik Tenaga Diesel (PLTD) berkapasitas kecil. Sistem tersebut memiliki berbagai keterbatasan, seperti jam operasi yang masih 12 jam, dan biaya bahan bakar tinggi. Kondisi ini berdampak pada rendahnya tingkat keandalan listrik serta terbatasnya akses energi masyarakat, sehingga diperlukan solusi inovatif yang lebih efisien dan berkelanjutan. Sebagai upaya untuk mengatasi permasalahan tersebut, penelitian ini dirancang untuk mengkaji penerapan sistem pembangkit listrik hybrid Diesel–PV–Battery sebagai alternatif pengganti atau pelengkap sistem diesel konvensional. Tujuan utama penelitian adalah melakukan analisis teknis dan ekonomi terhadap sistem hybrid tersebut guna memperoleh konfigurasi yang paling optimal dalam meningkatkan keandalan pasokan listrik selama 24 jam. Pendekatan yang digunakan bersifat kuantitatif deskriptif, dengan metode simulasi berbasis perangkat lunak HOMER Pro (Hybrid Optimization Model for Multiple Energy Resources). Hasil penelitian menunjukkan bahwa sistem hybrid optimal yang terdiri dari PLTS 3855 kWp, Battery Energy Storage System (BESS) 10651 kWh, dan generator diesel 600 kW, mampu memenuhi kebutuhan listrik selama 24 jam secara andal. Dari sisi ekonomi, sistem diesel only memiliki Net Present Cost (NPC) sebesar Rp 393,58 milyar dan Levelized Cost of Energy (LCOE) sebesar Rp 6.538,77/kWh. Penerapan sistem hybrid mampu menurunkan konsumsi bahan bakar dari 1.274.304 liter/tahun menjadi 166.838 liter/tahun sehingga NPC turun sebesar Rp 270,26 Milyar dan LCOE Rp 4.499,80/kWh. Dari aspek lingkungan, sistem hybrid mampu menurunkan emisi karbon secara signifikan dengan total penurunan sebesar 2.482,02 ton CO₂e/tahun. Penurunan emisi ini berpotensi memberikan nilai ekonomi tambahan melalui mekanisme Nilai Ekonomi Karbon, dengan estimasi sebesar Rp 74 juta hingga Rp347 juta per tahun.

The increasing demand for electrical energy in Indonesia has not been fully matched by equiTabel supply distribution, particularly in remote areas. One example is Gili Raja Island in Sumenep Regency, East Java, which still relies on diesel power plants with limited operating hours of 12 hours per day and high fuel costs. These limitations result in low electricity reliability and restricted energy access, highlighting the need for a more efficient and sustainable solution. To address this issue, this study investigates the implementation of a Diesel–PV–Battery hybrid power system as an alternative or complement to conventional diesel generation. The main objective of this research is to perform technical and economic analyses to determine the most optimal system configuration capable of providing continuous 24-hour electricity for Gili Raja Island, using HOMER Pro (Hybrid Optimization Model for Multiple Energy Resources) software as the primary simulation and optimization tool. The results show that the optimal hybrid system configuration, consisting of 3,855 kWp photovoltaic (PV), a 10,651 kWh Battery Energy Storage System (BESS), and a 600 kW diesel generator, is capable of reliably meeting electricity demand for 24 hours. Economically, the diesel-only system has a Net Present Cost (NPC) of IDR 393.58 billion and a Levelized Cost of Energy (LCOE) of IDR 6,538.77/kWh. The hybrid system significantly reduces fuel consumption from 1,274,304 liters/year to 166,838 liters/year, resulting in a lower NPC of IDR 270.26 billion and LCOE of IDR 4,499.80/kWh. From an environmental standpoint, the hybrid system achieves a substantial reduction in carbon emissions, totaling 2,482.02 tons CO₂e/year. This reduction also presents potential additional economic value through carbon pricing mechanisms, estimated between IDR 72 - 347 million per year.
