Abstract

Bioetanol gel memiliki beberapa kelebihan dibanding dengan bahan bakar padat briket maupun parafin yaitu terbarukan, selama pembakaran tidak berasap, tidak menimbulkan jelaga, memiliki kelebihan keamanan dalam hal distribusi, dan tidak mudah menguap. Penelitian ini bertujuan untuk mengarakterisasi produk bioetanol gel dengan variasi CMC, mengoptimasi performance pada bioetanol gel stove. Penelitian ini dilakukan secara eksperimen dimulai dengan proses pembuatan bioetanol gel dengan variasi komposisi CMC 2, 2.5, 3%. Karakterisasi bioetanol gel dilakukan melalui analisa proximate dan analisa ultimate. Aplikasi bioetanol gel dilakukan pada bioetanol gel stove, optimasi performance dalam penelitian ini adalah dengan menambah lubang saluran udara masukan diameter 1 inch dan 2 inch dengan variasi jumlah lubang sebanyak 2,4 dan 6. Parameter yang dihitung antara lain efisiensi thermal pembakaran, specific fuel consumption,daya api. Parameter yang diukur antara lain time to boil. Dari hasil penelitian yang telah dilakukan menunjukkan karakteristik bioetanol gel dengan pengental CMC 3% lebih baik dibandingkan bioetanol gel dengan pengental CMC 2% dan 2.5%. Karakteristik bioethanol gel dengan pengental CMC 3% menunjukkan hasil nilai kalor sebesar7380 kkal/kg, kadar air 11.2%, kadar abu 5.1%, kadar zat menguap 31.3%, kadar karbon terikat 51.4%. Berdasarkan hasil pengujian performance pembakaran pada bioetanol gel stove menunjukkan hasil bioetanol gel stove yang terbaik adalah pada diameter 1 inch dengan variasi 2 lubang udara masukan menggunakan jenis bahan bakar C dengan nilai efisiensi thermal pembakaran sebesar 28%, specific fuel consumption sebesar 0.060 gram bahan bakar/gram air , time to boil 12.2 menit, daya api sebesar 2.5 kW. ============================================================================================================= Bioethanol gel has several advantages over solid fuel briquettes and paraffin which is renewable, as long as the combustion does not smoky, does not cause soot, has a security advantage in terms of distribution, and not volatile. This study aims to characterize bioethanol gel product with variation of CMC, optimizing performance on bioethanol gel stove. This experiment was conducted by experimental and started with bioethanol gel making process with variation of composition of CMC 2, 2.5, 3%. Characterization of bioetanol gel is done through the analysis of proximate and ultimate analysis.. Application of bioethanol gel is done on bioethanol gel stove, performance optimization in this research is to increase the air-way (hole) with diameter 1 inch, and 2 inch. Parameters measured include thermal efficiency of combustion, specific fuel consumption, time to boil and power. Based on the results of research that has been done shows characteristic bioetanol gel thickener with CMC 3% better than the gel thickener bioetanol CMC 2% and 2.5%. Characteristics of bioethanol with gel thickener CMC 3% shows the result of a heat value of sebesar7380 kcal/kg, water content rate of 11.2%, 5.1%, ash levels of substances evaporate 31.3%, carbon levels tied to 51.4%. Based on the results of testing the performance of combustion on bioetanol gel stove stove gel bioetanol results shows it is best on a diameter of 1 inch with variation 2 input air holes using fuels with a rated thermal efficiency C burning by 28%, the specific fuel consumption of fuel/0060 grams grams of water, time to boil 12.2 seconds, the fire power of 2.5 kW.
