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
