Abstract

Alang-alang (Imperata cylindrica (L.) Beauv.), merupakan tanaman pengganggu pada tanaman padi, tebu, jagung, dan sebagainya. Namun, tanaman ini mengandung bahan selulosa yang dapat dikonversi menjadi gula sederhana, sehingga dapat dijadikan sumber bahan baku ethanol. Penelitian ini bertujuan untuk mengetahui efektivitas ethanol yang berasal dari bahan baku alang-alang (Imperata cylindrica (L.) Beauv.) terhadap lama pembakaran dan titik didih kompor bioetanol. Konsentrasi ethanol 70%, 90% dan 93% digunakan sebagai variasi perlakuan untuk memperoleh ethanol yang efektif sebagai bahan bakar kompor bioetanol. Pada penelitian ini proses pretreatment dilakukan secara mekanis, fisik dan kimiawi terlebih dahulu dengan cara penjemuran, penggilingan dan perendaman NaOH. Selanjutnya proses sakarifikasi menggunakan enzim StargenTM 002 (no cook), lalu fermentasi dengan menambahkan urea, NPK, serta Saccharomyces cereviseae. Dari hasil ini diperoleh bahwa alang-alang yang difermentasi terbukti mampu menghasilkan ethanol sebanyak 600 ml konsentrasi 93% dari hasil destilasi. Ethanol konsentrasi 93% diencerkan menjadi konsentrasi 70% dan 90 %. Dari hasil uji lama pembakaran pada kompor bioetanol dan pengamatan titik viii didih didapati bahwa ethanol pada konsentrasi 93% adalah perlakuan terbaik untuk bahan bakar kompor bioetanol. ============================================================================================================ Cogongrass (Imperata cylindrica (L.) Beauv.), was a disrupter plant on the rice, sugar cane, or even corn. However, this plant is contained cellulose material that can be converted into simple sugars, thus bioethanol might be produced. This research aimed to understand the effectiveness of bioethanol derived from cogongrass raw materials toward boiling and cooking time for bioethanol burning stove. Bioethanol at concentration 70%, 90% and 93% were as the variation of treatment to obtain effective bioethanol as fuel for bioethanol stove. On this research pretreatment process conducted mechanically, physically and chemically beforehand by means of a place to spread, milling and soaking by NaOH. The process of saccharification used StargenTM 002 (no cook enzyme) then fermented by Saccharomyces cereviseae with urea, NPK, as well as fertilizer. This result obtained that cogongrass had proven it able to produce 600 ml ethanol at concentrations 93% of from the distillation results. Ethanol concentration 93% had diluted into the concentration of 70% and 90%. Results informed from the burning on the bioethanol stove through observation at the boiling and cooking time, it gave us data that burning ethanol at x concentrations 93% was the best treatment for bioethanol stove
