Abstract

Semakin menipisnya persediaan minyak dunia menyebabkan kelangkaan bahan bakar berupa bensin dan minyak tanah Untuk menanggulangi hal tersebut pemerintah menggalakkan pemakaian bahan bakar nabati berupa bioethanol. Bioetanol merupakan etanol atau etil alkohol (C2H5OH) dari hasil fermentasi glukosa (C6H12O6) yang berasal dari bahan baku nabati. Pada penelitian ini pembuatan bioethanol berasal dari limbah kulit pisang. Tujuan dari penelitian ini yaitu mengetahui hasil bioetanol setelah didestilsi 95% dan 99% serta pengaruh kadar bioetanol yang berasal dari kulit pisang (M. paradisiaca) sebagai bahan bakar campuran terhadap mesin sepeda motor. Metode yang dilakukan terdiri dari persiapan bahan, pretreatment, hidrolisis, fermentasi, destilasi, uji propertis bioethanol dan uji unjuk kerja mesin dengan parameter penyalaan awal, konsumsi bahan bakar spesifik dan emisi. Hasil yang didapatkan yaitu menghasilkan kadar gula 20%, fermentasi menghasilkan kadar etanol 12% dan destilasi 95% sebanyak 900 ml dan 99% sebanyak 700 ml. Kadar etanol berpengaruh pada mesin sepeda motor, campuran B50 99% menghasilkan hasil lebih cepat dari B50 95% pada penyalaan awal yakni 3-4 kali stater dan akselerasi selama 9-10 detik, paling lama pada konsumsi bahan bakar spesifik yakni rata-rata 169 detik serta paling rendah pada emisi CO dengan rata-rata 0,0815% dan paling tinggi pada emisi CO2 dengan rata-rata 2,28%.

The depletion of world oil supplies causes scarcity of fuel in the form of gasoline and kerosene. To overcome this, the government promotes the use of biofuels in the form of bioethanol. Bioethanol is ethanol or ethyl alcohol (C2H5OH) from glucose fermentation (C6H12O6) derived from vegetable raw materials. In this study the manufacture of bioethanol originated from banana peel waste. The purpose of this study is to find out the results of bioethanol after being tested 95% and 99% as well as the effect of bioethanol levels derived from banana peels (M. paradisiaca) as a mixture of fuels on motorcycle engines.. The method used in this research consisted of material preparation, pretreatment, hydrolysis, fermentation, distillation, bioethanol property test and engine performance test with initial ignition parameters, specific fuel consumption and emissions. The results obtained in this study were to produce 20% sugar content, fermentation produced 12% ethanol content and 95% distillation of 900 ml and 99% as much as 700 ml. The ethanol level affects motorbike engines, the B50 99% mixture produces faster results in the initial ignition, which is 3-4 times the accelerator, the longest on specific fuel consumption, which is an average of 209 seconds and the lowest on average CO emissions average of 0.0815% and the highest in CO2 emissions with an average of 2.28%.
