Abstract

AbstrakTujuan dari penelitian ini adalah  mengetahui pegaruh konsentrasi asam dan waktu hidrolisis terhadap kadar gula total serta kadar gula reduksi. Metode penelitian yang digunakan adalah Rancang Acak Kelompok (RAK) faktorial 2 faktor yaitu konsentrasi H2SO4 dan lama waktu hidrolisis. Faktor pertama terdiri dari 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 (27 sampel). Selanjutnya, dilakukan uji kadar gula total menggunakan refraktometer dan kadar gula reduksi menggunakan Nelson Somogyi. 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%.Kata kunci: bioetanol, gula, hidrolisis, pelepah sawit AbstractThe purpose of this research was to determine the effect of acid concentrations and hydrolysis time. Randomized Completely Block Design were arranged in a factorial with two factors : H2SO4 concentrations were 0.4M, 0.6M, 0.8M and hydrolysis time were 60 minutes, 80 minutes, 100 minutes. Each combination repeated three times. Samples were tested of total sugar content using refractometer and were tested of reducing sugar using Nelson Somogyi. Data were analyzed used two-ways ANOVA and conducted further test using the DMRT 5%. The result showed that the highest total sugar content is 10.7% in the treatment of H2SO4 concentration  0.6M 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. Pretreatment oil palm frond using H2SO4 was produced 4% etanol after fermentation.Keywords: bioetanol, hydrolysis, oil palm frond, sugar
