Abstract

Merencanakan Pembanngkit Listrik Tenaga Surya (PLTS) sebagai pengganti listrik alternatif daerah pesisir pantai selatan Desa Tumpak Pucung. Daerah tersebut daerah sangat minim akses penerangan disebabkan karena letek daerah jauh dari perkotaan sehingga untuk akses penerangan masih blm bias terdistribusi. Untuk merencanakan Pembanngkit Listrik Tenaga Surya (PLTS energi listrik alternative. Metode analisa, observasi lapangan, serta perencanaan alat dan komponen kemudian akan digunakan pada pengabdian. Pengabdian dilakukan di Desa Tumpak Pucung Malang. Besar daya listrik dibutuhkan penduduk mencakup rumah penduduk, fasilitas umum, penerangan jalan. Total kebutuhan komponen panel surya atau sollar panel dibutuhkan untuk membangkitkan energi sebesar 18.408 watt dibutuhkan panel surya dengan kapasitas 250 wp sebanyak ±10 unit. Diperlukan charge controller sebanyak satu unit dengan kapasitas 100 ampere. Total jumlah batree dan inverter dibutuhkan masing-masing sebanyak 12 unit batree dan 2 unit inverter

Abstract

Calophyllum Inophyllum (nyamplung) Oil is recognized as a promising non-edible vegetable oil for the development of sustainable green energy lubricants. This study aims to improve the physicochemical characteristics of nyamplung oil through a two-step transesterification followed by esterification using trimethylolpropane (TMP), and to assess its tribological performance. The refined oil exhibited a flash point of 212 °C (ASTM D92) and a pour point of 8 °C (ASTM D97), indicating excellent thermal and flow stability. The kinematic viscosity was 38.3 cSt (ASTM D445) and the density 0.88 g/cm³ (ASTM D4052), both within industrial lubricant standards. The acid value decreased markedly from 36.5 to 1.62 mg KOH/g, while the iodine value (0.006 g I₂/100 g) and peroxide value (0.23 Meq/kg) demonstrated chemical stability. FTIR analysis confirmed the formation of ester functional groups, and GC–MS results showed a balanced distribution of saturated and unsaturated fatty acids. Overall, the modified Calophyllum Inophyllum Oil fulfills key technical criteria for eco-friendly green energy lubricants and shows strong potential as a renewable alternative to conventional mineral-based lubricants in industrial applications. Nevertheless, its crude form presents several drawbacks, including high acid and peroxide values as well as poor oxidative stability.
