PRODUK BIOETANOL DAGING BUAH SAWO (MANILKARA ZAPOTA L.) SECARA FERMENTASI BATCH DENGAN SACCHAROMYCES CEREVISIAEBioethanol Product from Fruit Sawo ( Manilkara zapota L. ) in Batch
Fermentation by Saccharomyces cerevisiaeCreated by :
Yonatan Eden ( none ) Sri Teguh Rahayu
Subject: | BIOETANOL BUAH SAWO | Alt. Subject : | FERMENTATION BIOETHANOL | Keyword: | FERMENTASI |
Description:
Buah sawo (Manilkara zapota L.) merupakan komoditas perkebunan yang sejauh ini
kurang dimanfaatkan masyarakat Indonesia dan penelitian menunjukkan bahwa sawo
memiliki kandungan karbohidrat yang sangat tinggi (72,8%). Pada penelitian ini senyawa
karbohidrat yang terkandung pada daging buah sawo digunakan sebagai substrat oleh
Saccharomyces cerevisiae untuk membentuk senyawa alkohol. Adanya enzim intracellular
β-glucosidase (GH1-1), mampu mengubah senyawa karbohidrat yang terkandung dalam
daging buah sawo menjadi etanol. Pada penelitian ini etanol diperoleh dari hasil fermentasi
selama 144 jam secara aaerob pada suhu ruang. Adanya variasi jumlah inoculum yang
ditambahkan ke dalam medium fermentasi (5; 7,5 dan 10% (v/v) menunjukkan ada
peningkatan kadar etanol yang dihasilkan, di mana berturut-turut 5,0; 6,0; dan 6,5% (v/v).
Hasil pemurnian dengan metode destilasi pada suhu 78 ˚C juga memperlihatkan kemurnian
produk yang tinggi, yakni berturut-turut 80, 82 dan 83%. Oleh karena itu, produk
biomassa ini dapat dikategorikan sebagai bahan alternatif penganti BBM.
Alt. Description
Sapodilla fruit (Manilkara zapota L.) is a commodity that�s very less useful in Indonesian
and research shows that sapodilla fruit has high carbohydrate content (72.8%). In this
study, the composition contained in sapodilla fruit was used as a substrate by
Saccharomyces cerevisiae to convert carbohydrate to be alcohol compounds. The presence
of intracellular enzymes, β-glucosidase (GH1-1) able to convert the carbohydrate
compounds in sapodilla fruit into ethanol. In this study ethanol was obtained from
fermentation for 144 hours by anaerob at room temperature. The variation in the amount of
inoculum added to the fermentation medium (5; 7.5 and 10% (v / v) showed that there was
an increase in the ethanol content produced (5.0; 6.0; and 6.5% (v / v)). The purification
method by the distillation method at a temperature of 78 ˚C also assesses the high purity of
the product (80, 82 and 83%).
