Abstract

Renewable energy is one of the businesses sector that will develop rapidly after the changing economic order due to the corona outbreak. The characteristics of Indonesia's tropical climate by getting good sunlight throughout the year can be used as alternative and renewable energy. The Stirling engine is one type of external combustion engine, because combustion is carried out outside the engine using a closed regenerative cycle in which the working fluid is compressed or expanded in a separate reservoir and then distributed to drive the power piston reciprocatingly. The method developed is the use of solar energy which is concentrated by a parabolic reflector to the hot cylinder of the Stirling engine to convert heat energy into motion energy. The purpose of this study was to determine the effect of the thermal conductivity of several material specimens used in the hot cylinder of the Stirling engine including copper, stainless steel, & glass. This study uses an experimental method to describe the performance of a stirling engine prototype using various types of hot cylinder material specimens. The results showed that the gamma stirling engine using hot cylinder glass material had the best performance because with a heat conductivity of 0.78 W/m˚C it was able to drive a stirling engine with a speed of 132 rpm and a torque of 0.57 N.mm at the temperature difference between hot cylinder and cold cylinder of 88˚C and with a thermal efficiency of 20.39%.

Abstract

Kecamatan Poncokusumo merupakan salah satu wilayah diantara 33 Kecamatan yang saat ini terdapat di Kabupaten Malang,yang secara geografis merupakan kawasan dengan kondisi lahan berupa hamparan lahan yang cenderung berbukit-bukit karena berada di sebelah barat lereng gunung semeru yang sebagian besar merupakan lahan produktif berada pada ketinggian antara 600 sampai dengan 1200 meter diatas permukaan laut dengan curah hujan rata-rata antara 2300 mm sampai dengan 2500 mm per tahun dan suhu rata-rata 19,7 derajat celcius. Di dusun Sukosari masih menggunakan kayu bakar sebagai bahan bakar untuk memasak, fasilitas pengolahan limbah hewan ternak sapi belum ada, biasanya kotoran sapi langsung dibuang ke selokan-selokan. Solusi permasalahan adalah Memberikan penyuluhan dan penjelasan tentang penerapan serta pemanfaatan teknologi reaktor biogas dengan memanfaatkan kotoran hewan ternak. Memberikan wawasan energi terbarukan kepada mitra dalam pemanfaatan kotoran hewan ternak sehingga diharapkan  kebutuhan dan ketergantungan terhadap bahan bakar minyak dapat terkurangi. Bertambahnya pengetahuan mitra tentang potensi kotoran hewan ternak yang dapat dipergunakan sebagai energi terbarukan guna menunjang perekonomian warga. Kata kunci: Poncokusumo, kayu bakar, limbah, sapi, biogas
