Abstract

Pemerintah dalam tujuannya mencapai target bauran energi terbarukan sebesar 23% pada tahun 2025 terus mendorong masyarakat dalam menggunakan energi terbarukan, terutama di jenis energi surya melalui pemanfaatan PLTS Atap. Dalam pembangunan sistem PLTS Atap, perlu dilakukan perancangan sistem PLTS terlebih dahulu, untuk mengkalkulasi energi yang dapat dihasilkan pada sistem tersebut. Perhitungan potensi daya listrik perlu dilakukan karena merupakan salah satu dari tahap perencanaan dalam pembangunan sistem PLTS. PLN UID Riau dan Kepri hendaknya dapat ikut berkontribusi dalam mengembangkan dan mensosialisasikan peraturan pemerintah tersebut dengan cara mengembangkan dan mensosialisasikan PLTS Atap di lingkungan Gedung PLN UID RKR. Untuk itu dalam penelitian ini dilakukan perhitungan potensi energi listrik dari PLTS Atap jika dilakukan pengaplikasian teknologi PLTS Atap di lingkungan Gedung PT PLN (Persero) UID Riau dan Kepri sebagai salah satu tahapan dalam perancangan suatu sistem. Dari simulasi PVsyst yang telah dilakukan didapat potensi energi listrik di Gedung PT PLN UID RKR sebesar 9321 kWh/tahun atau 25,56 kWh/hari dengan kapasitas PLTS sebesar 6,08 kWp. Untuk Performance Ratio dari sistem PLTS ini sebesar 0,82. Kata kunci: PLTS Atap, PVsyst, energi surya

Abstract

Cheese is one of the popular dairy products with high nutrient content. Coagulation as an important process in making cheese, wherein, the curd will be separated from the milk whey. This coagulation can use the enzyme rennet, acid, or a combination of both. This study aims to study the effect of coagulant agents on yield, protease enzyme activity, and curd texture on cheese making. Coagulant agents used are acetic acid, citric acid, lime and lemon combined with the enzyme rennet. The process begins with pasteurized milk and analyzed, the milk is pasteurized and analyzed first to obtain moisture content, density and pH. The coagulant added is 25-45% with a base of 50 ml of milk and 5 mL of the enzyme rennet. The curd formed is then separated from the whey using a filter cloth and analyzed for its water content and pH. The coagulant of acetic acid and citric acid produced a higher yield curd of 94.66% (4% acetic acid) and 93.9% (5% citric acid) compared to the highest yield of curd that can be produced by lime and lemon coagulant which is 68 72% (lemon orange 45%) and 61.84% (lime 45%). The texture of the curd formed by lime and lemon juice is more fragile than the curd texture with coagulant of acetic acid and citric acid. Each coagulant provides a diverse response to protease enzyme activity.
