Abstract

Counselling about the use of alternative energy has been carried out at SMAN 1 Labuapi as a partner. This counselling needs to be done because based on the analysis of the situation, the people around SMAN 1 Labuapi desperately need energy assistance. Meanwhile, in the area around the SMAN 1 Labuapi, there is plenty of alternative energy. Therefore, the main purpose of implementing community service is to motivate the community, especially the community of SMAN 1 Labuapi, to be able to provide their own energy. Then, it is hoped that SMAN 1 Labuapi is expected to provide a model of alternative energy utilization to meet the energy needs of the wider community of Desa Labuapi continuously. The method used in this service is the method of counselling and demonstration about the use of alternative energy. The results of service are changes in the behaviour of the people of SMAN 1 Labuapi to utilize alternative energy. One tool that had been practised was a biogas maker unit using gallons of Narmada.

Abstract

Sebagai generasi milenial, siswa sekolah menengah atas perlu dilengkapi dengan pemahaman bahwa sumber energi fosil saat ini mulai terbatas ketersediaannya sehingga perlu ekstensifikasi sumber energi. Dari beberapa sumber energi alternatif pengganti energi fosil, biogas merupakan salah bentuk energi yang potensial untuk dikembangkan. Biogas sangat mudah diproduksi sebab tidak perlu ketrampilan khusus, demikian pula bahan dan material yang digunakan sangat mudah diperoleh dan tidak membutuhkan biaya yang besar. Pengabdian ini khusus ditujukan kepada siswa SMA untuk membuka wawasan mereka sebab pada kelompok umur tersebut adalah salah satu pengguna energi fosil terbesar. Disamping itu masa depan penentu kebijakan penggunaan energi ada pada generasi mereka. Pengabdian ini telah berhasil memberikan motivasi dan kesadaran tentang pentingnya upaya inovasi untuk mengembangkan sumber energi terbarukan khususnya pemanfaatan biogas sebagai bahan bakar pengganti energi fosil.

Abstract

The sandwich composite used in this investigation has a bamboo open-cell foam core and a plywood skin. In this study, the density, flatwise compressive strength, flexural strength, and water absorption of sandwich composite materials will be determined. The volume proportion of fiber in the bamboo foam core was 15% in this investigation, and PVAc adhesive was employed. The open-cell foam core has a square-shaped hollow in the center and hole spacings of 30mm, 40mm, and 60mm. The tests included density testing (ASTM C271), flatwise compression testing (ASTM C365-05), flexural testing (ASTM C393), and water absorption testing (ASTM C272). According to the study's findings, compared to sandwich composites with core-opened cell foam without holes, sandwich composites with core-opened cell foam with holes have an average density, an average specific flatwise compressive strength, and an average specific bending strength that are smaller. The percentage of water absorption in the sandwich composite demonstrates the opposite. Comparing the sandwich composite with core-opened cell foam without holes (0.45 g/cm3) to the sandwich composite with core-opened cell foam with holes, the average density of the latter decreased by 6–13%. The decrease in the avarage specific flatwise compressive strength of the sandwich composite with a hollow core was 2-20% compared to the sandwich composite with an open-cell foam core without holes (41.22 MPa/cm3/gr). The average specific bending strength of the sandwich composite with the core opened cell foam with holes was reduced by 40–50% when compared to the sandwich composite with the core opened cell foam without holes (26.38 MPa/cm3/gr).
