Rilek, Nada Mawarda (2017) Hidrolisis Lignoselulosa Hasil Pretreatment Pelepah Sawit (Elaeis Guineensis Jacq) Menggunakan Asam (H2so4) Pada Produksi Bioetanol. Sarjana thesis, Universitas Brawijaya.
Abstract
Bioetanol berbahan baku non panganmulai dikembangkan berupa lignoselulosa pelepah sawit yang mimiliki kandungan selulosa 30-33%. Proses pembuatan bioetanol dari lignoselulosa cukup panjang yaitu pretreatment, hidrolisis dan fermentasi. Proses pretreatment menggunakan metode pemberian gelombang ultrasonik dan basa NaOH. Hidrolisis dilakukan dengan penambahan H2SO4 dan fermentasi menggunakan Saccharomices cerevisiae. Tujuan penelitian ini adalah mengetahui pengaruh konsentrasi asam dan waktu hidrolisis terhadap kadar gula dan mengetahui kadar gula reduksi yang dihasilkan. Rancangan percobaan yang digunakan adalah RAK faktorial 2 faktor yaitu konsentrasi H2SO4 dan lama waktu hidrolisis. Faktor pertama terdiridari tiga level yaitu 0,4M, 0,6M dan 0,8M, sedangkan faktor kedua terdiri dari tiga level yaitu 60 menit, 80 menit dan 100 menit dari rancangan tersebut diperoleh sembilan kombinasi. Pada setiap kombinasi dilakukan tiga ulangan. Data kemudian dianalisis menggunakan ANOVA dan uji DMRT 5%. Hasil pengamatan menunjukkan kandungan gula total tertinggi saat proses hidrolisis adalah perlakuan H2SO4 0,6M dengan waktu 100 menit yaitu 10,7%. Berdasarkan uji Anova dan DMRT5% bahwa kedua faktor perlakuan berpengaruh signifikan terhadap kadar gula dan berbeda nyata. Gula reduksi yang dihasilkan pada proses hidrolisis sebesar 19,29%. Dari bahan tersebut didapatkan etanol hasil fermentasi sebesar 4%.
English Abstract
Bioethanol was developed fromlignocellulose palm frond which contain cellulose about 30-33%. The process of making bioethanol can be done with few processes, such as pretreatment, hydrolysis, and fermentation. The process of pretreatment using ultrasound wave and NaOH. The hydrolysis process used H2SO4 and fermentation process used Saccharomyces cerevisiae. The purpose of this study was to determine the effect of acid concentration and hydrolysis time to know the sugar content and reducing sugar produced. The experimental design used was Randomized Block Design that were arranged in a factorial with two factors : H2SO4concentration which concist of three levels 0,4M, 0,6M, 0,8Mand hydrolysis time which concist of three levels 60 minutes, 80 minutes, 100 minutes. Each combination repeated three times to obtain 27 samples. Then, Data were analyzed used two-way ANOVA and conducted further test using the DMRT 5%. The result showed that the highest total sugar content is 10.7% in the treatement of H2SO4concentration 0.6 M and hydrolysis time 100 minutes. Based on ANOVA and DMRT test, all factors had significantly effect of the percentage of sugar. Beside that, in this research also have reduction sugar about 19.29% from sugar content of result hydrolysis process . That material produce 4% ethanol.
