Abstract

The need for electrical energy in Indonesia is increasing, while dependence on fossil fuels remains dominant. One potential alternative is the utilization of solar energy through rooftop Solar Power Plants (PLTS). This study aims to design a rooftop PLTS system in the Integrated Classroom and Laboratory Building, Campus 1, Siliwangi University with a technical and economic approach. The research method includes collecting data on load profiles and potential solar radiation, designing system capacity, selecting main components, and simulating using PVsyst software to obtain estimates of energy production and system performance. The planning results show a design capacity of 71,107 Wp with a configuration of 118 solar panels with a capacity of 600 Wp, which produces energy production of around 299–318 kWh per day or equivalent to 109–116 MWh per year. The PVsyst simulation produces an average Performance Ratio value of around 80%, which is in the good category. However, the economic analysis using the Net Present Value (NPV) method shows a negative value (−996,310,000), so this project is not yet financially feasible if implemented in a fully off-grid scenario. In conclusion, the implementation of rooftop solar power plants in the Integrated Classroom and Laboratory Building, Campus 1, Siliwangi University is technically feasible, but not yet financially feasible under current conditions. Therefore, it is recommended to implement a hybrid or on-grid scenario, as well as an electricity tariff sensitivity analysis to increase economic feasibility.

Abstract

Data dari Dinas Kesehatan Kota Tasikmalaya menunjukan bahwa sampai tanggal 19 Juni 2020 jumlah kasus positif melalui PCR dan RDT berjumlah 50. Puskesmas Kecamatan Cibeureum dan MAN 2 Tasikmalaya sebagai mitra perlu mempersiapkan diri untuk menghadapi adaptasi kebiasaan baru. Salah satu yang harus mendapatkan perhatian adalah bahaya penularan Covid-19 melalui kontak langsung dengan dokumen-dokumen yang memiliki mobilitas perpindahan tangan yang cukup tinggi mengingat dokumen tidak bisa disterilisasi menggunakan cairan disinfektan. Solusi yang ditawarkan adalah dengan memberikan alat sterilisasi dokumen-dokumen dengan teknologi Sinar Ultraviolet tipe C (UVC) kepada mitra Puskesmas Cibeureum dan MAN 2 Tasikmalaya, beserta edukasi terkait dengan aturan dan cara menggunakan alat sterilisasi dokumen tersebut. Berdasarkan data, tingkat pemahaman mitra terkait dengan covid-19, penggunaan teknologi UVC dan dampak negatif yang harus dihindari dari penggunaan teknologi tersebut mengalami peningkatan yang sangat signifikan. Selain itu, teknologi yang diterapkan oleh mitra tersebut khususnya teknologi UVC sangat bermanfaat dan dapat digunakan dengan mudah oleh mitra.
