Pembuatan Bioetanol dengan Cara Hidrolisis Menggunakan Kertas Koran Bekas serta Pemurnian Menggunakan Agen Pengering (MgSO4, Na2SO4, dan CaCl2)

Abstract

This research was performed to: (1) utilize newspaper as raw material for bioethanol production and (2) examine the effectively of bioethanol purification of newspaper by using Na₂SO₄, CaCl₂, and MgSO₄ substances. This research was used by experimental method. First step of bioethanol production wasconducted using a pretreatment process to break down the lignin content. Hydrolysis of newspaper was done enzymatically using the cellulose enzyme. Bioethanol purification method of newspaper was done through destillation and desiccantion methods using MgSO₄, Na₂SO₄, and  CaCl₂ as drying agent. Bioethanol characterization was determined by Gas Chromatography/Mass Spectroscopy (GCMS) and  Fourier Transform Infrared Spectroscopy (FTIR). The results of this research indicated as follows: (1) newspaper can be used as raw material for second generation of bioethanol production with pretreatment process, enzymatical hydrolysis, fermentation, and destillation and (2) NaSO₄, CaCl₂, and MgSO₄ substances can be used to purify bioethanol with MgSO₄ as the most optimum substances for  purifying bioethanol from newspaper.
