Implementasi PLTS Rooftop sebagai Solusi Energi Mandiri Hemat Biaya bagi Rumah Tangga di Ponpes Riyadhul Awamil, Rumpin, Bogor, Jawa Barat

Abstract

Peningkatan kebutuhan energi listrik rumah tangga menyebabkan konsumsi listrik nasional terus meningkat, bergantung pada energi fosil, serta menimbulkan dampak lingkungan berupa emisi karbon dan kenaikan biaya energi. Solusi yang dapat diterapkan adalah penggunaan Pembangkit Listrik Tenaga Surya (PLTS) Rooftop Off-Grid pada sektor rumah tangga. Penelitian ini bertujuan untuk menganalisis penerapan energi mandiri yang hemat biaya di Pondok Pesantren Riyadhul Awamil, Rumpin, Bogor, Jawa Barat. Metode yang digunakan meliputi studi literatur, analisis kebutuhan energi rumah tangga di sekitar kawasan, perancangan kapasitas sistem PLTS, serta analisis ekonomi penghematan biaya listrik dan Return on Investment (ROI). Studi kasus dilakukan pada rumah tangga sekitar dengan daya listrik 2.200 VA dan konsumsi energi rata-rata 10–12 kWh per hari. Hasil penelitian menunjukkan bahwa sistem PLTS Rooftop berkapasitas 4 kWp mampu menghasilkan energi listrik rata-rata 392–420 kWh per bulan dengan penghematan biaya listrik sebesar Rp500.000–Rp750.000 per bulan. Investasi awal sistem berkisar Rp45.000.000–Rp55.000.000 dengan periode pengembalian modal sekitar 7–10 tahun. Implementasi ini terbukti mampu meningkatkan kemandirian energi warga sekitar, mengurangi emisi karbon, dan mendukung program energi baru terbarukan di Indonesia.

ABSTRACT

The increasing demand for household electrical energy causes national electricity consumption to continuously rise, heavily relying on fossil fuels and impacting the environment through carbon emissions and rising energy costs. A potential solution is the implementation of Off-Grid Rooftop Solar Power Plants (PLTS) in the household sector [1, 2]. This study aims to analyze cost-effective independent energy implementation at the Riyadhul Awamil Islamic Boarding School, Rumpin, Bogor, West Java. The methodology includes a literature study, analysis of surrounding household energy needs, design of PLTS system capacity, and economic analysis of electricity cost savings alongside Return on Investment (ROI). The case study was conducted on surrounding households with a 2,200 VA electrical grid connection and an average energy consumption of 10–12 kWh per day. The results show that a 4 kWp Rooftop PLTS system generates an average of 392–420 kWh of electrical energy per month, yielding electricity cost savings of IDR 500,000–750,000 per month. The initial system investment ranges from IDR 45,000,000 to IDR 55,000,000, with a payback period of approximately 7–10 years. This implementation is proven to enhance energy independence, reduce carbon emissions, and support new and renewable energy programs in Indonesia.
