Abstrak

ABSTRAK Etanol merupakan bahan kimia dengan fungsi yang beragam, dan kebutuhannya terus meningkat. Teknologi produksi etanol saat ini masih berbahan baku pati yang bersaing dengan bahan pangan. Pabrik etanol ini didirikan dengan tujuan memenuhi kebutuhan yang terus meningkat, dengan bahan baku Ampas Tebu yang tidak bersaing dengan bahan pangan. Pabrik Etanol ini direncanakan didikan di Terusan Nunyai, Lampung Tengah, Provinsi Lampung. Kapasitas produk etanol adalah 32.000 ton/tahun dan membutuhkan ampas tebu sebesar 450 ton/hari. Pabrik beroperasi 24 jam/hari, 330 hari/tahun. Kebutuhan utilitas diantaranya adalah pengadaan air Water Treatment Plant (WTP), penyediaan listrik dan steam, penyediaan bahan bakar, dan penyediaan udara tekan. Bentuk perusahaan adalah Perseroan terbatas, berstruktur organisasi line and staff dengan kebutuhan karyawan 132 orang. Keekonomian Pabrik Etanol Ampas Tebu ini adalah Fixed Capital Investment (FCI) = Rp 447.434.177.404 Working Capital Investment (WCI) = Rp 304.580.419.228 Total Capital Investment (TCI) = Rp 752.014.596.632 Break Even Point (BEP) = 55,07 % Shut Down Point (SDP) = 22,89 % Pay Out Time after taxes (POT)a = 3,5 tahun Return on Investment after taxes (ROI)a = 64,34 % Discounted cash flow (DCF) = 21,59 % Hasil studi kelayakan teknik dan ekonomi menyatakan bahwa, Pabrik Etanol Ampas Tebu layak dikaji lebih lanjut, karena menguntungkan dan beresiko rendah. Kata Kunci : Etanol, Ampas Tebu, Selulosa, Hidrolisis, Fermentasi. ABSTRACT Ethanol is chemical substance with variety in function. The demand of Ethanol keeps growing, and at present the production technology still use polysaccharide as raw material which compete with food. The purpose of this Ethanol Plant is supplying the demand, with Bagasse as raw material that doesn’t compete with food. Ethanol plant planned to be built at Terusan Nunyai, Lampung Tengah, Lampung Province. Plant capacity is 32.000 ton/year which need Bagasse 450 ton/day. The plant operates in 24 hrs./day, 330 days/year. Utility plant supply water in Water Treatment Plant (WTP), supply electricity and steam, supply fuel and supply pressed air. The company entity form is Limited Liability Company (PT) with line and staff organization structure. Total labor is 132 peoples. Economic study of the plant is Fixed Capital Investment (FCI) = Rp 447.434.177.404 Working Capital Investment (WCI) = Rp 304.580.419.228 Total Capital Investment (TCI) = Rp 752.014.596.632 Break Even Point (BEP) = 55,07 % Shut Down Point (SDP) = 22,89 % Pay Out Time after taxes (POT)a = 3,5 tahun Return on Investment after taxes (ROI)a = 64,34 % Discounted cash flow (DCF) = 21,59 % The result of technical and economic feasibility study is feasible and need further analysis, because the plant is profitable with good sustainability. Key Word : Ethanol, Bagasse, Cellulose, Hydrolysis, Fermentation
