Abstract

Sumber bahan bakar utama masyarakat saat ini adalah gas dan bahan bakar dari bahan fosil yang merupakan bahan bakar yang tak dapat diperbaharui (nonrenewable). Bioarang buah pinus atau dikenal dengan buah tusam bisa menjadi bahan bakar alternatif khususnya bagi masyarakat yang berdomisili disekitar kawasan hutan pinus atau bagi kalangan industri rumah tangga. Briket berkualitas tinggi dapat dihasilkan dari proses pirolisis, yaitu suatu proses termal dengan kondisi sedikit atau tanpa adanya oksigen. Variabel yang diamati pengaruhnya terhadap mutu briket yaitu sifat fisik dan kimia dengan analisis proximate arang briket buah tusam, juga komposisi terbaik buah tusam dengan variasi konsentrasi kanji sebagai bahan perekatnya serta kualitas pembakaran briket buah tusam. Kegunaan penelitian ini yaitu sebagai bahan informasi bagi masyarakat umum yang tertarik untuk menggunakan briket sebagai bahan bakar. Hasil terbaik ditunjukkan pada rasio 85 : 15 % berat, dimana Uji sifat kimia kadar abu : 1.50 % berat; zat mudah menguap: 21.08 % berat; karbon tetap : 70.20 % berat. dan uji kualitas sifat fisika Nilai kalor : 6.577 kcal/kg; Kadar air : 6.87 %, dan Kualitas bakar selama 99 menit.

Abstract

Bioethanol derived from cassava has the potential as an alternative energy material because cassava plants contain starch, sugar or cellulose which can be used in the process of making alternative and environmentally friendly fuels. This study aims to make bioethanol from cassava starch. This research method starts from material preparation to the process stage consisting of the fermentation process, distillation process, and the final stage, namely testing ethanol content and adding fuel. 5 kg of cassava is used to produce 98 ml of bioethanol distillation with 16% rendition. The combustion test was carried out to obtain a comparison of the calorific value between the fuel mixture - Bioethanol and fuel -Alcohol, Mixing partalalite - Bioethanol 1: 19 (95% partalaite: 5% Bioethanol) and fuel - Alcohol 1: 19 (95% partalite: 5 % alcohol). The results of the research obtained the calorific value of combustion of the partalalite - alcohol mixture: 11,649.48 kcal/kg, while for the partalalite - bioethanol mixture: 11,486.15 kcal/kg. So that the higher the concentration of ethanol mixed in partalite, the higher the calorific value.

Abstract

This study aims to analyse the potential energy that can be generated from municipal solid waste (MSW) at Tamangapa landfill, check the adequacy of energy according to the target of 20 MW/day, and give consideration to WtE technologies that can be applied. The research began with a literature study, followed by a quantitative approach to calculate the potential energy that can be generated through incineration, gasification, pyrolysis, anaerobic digestion (AD) and fermentation WtE technologies. The results showed that the energy target of 20 MW/day from MSW in Makassar can be met through incineration (168.80 MW/day), gasification (28.29 MW/day) and pyrolysis (62.03 MW/day). However, if 20 MW/day is clean energy, then considering the energy conversion efficiency, 30.38 MW/day is obtained for incineration, 7.07 MW/day for gasification, and 15.51 MW/day for pyrolysis. Based on this calculation, only incineration technology can fulfil the 20 MW/day energy target as expected. In order to maximise the energy potential, it is recommended to use a combination of incineration WTE technologies for plastic, rubber, paper and fabric components, and pyrolysis for wood and food waste components.
