Abstract

ABSTRAKPenelitian ini bertujuan untuk mengidentifikasi produktivitas bioetanol dari unbeaten pulp, beaten pulp, non-printed paper dan laser-printed paper dengan menggunakan metode sakarifikasi dan fermentasi simultan (simultaneous saccharification and fermentation – SSF). Khamir yang digunakan adalah Saccharomyces cerevisiae, diaplikasikan dalam konsentrasi 10%, 15% dan 20%, dengan waktu inkubasi selama 3, 4, dan 5 hari. Konsentrasi etanol dianalisis menggunakan kromatografi gas, kemudian digunakan untuk menghitung rendemen etanol dan konversi selulosa. Kadar karbohidrat sampel yang cenderung tinggi (lebih dari 70%) mengindikasikan bahwa pulp yang digunakan berpotensi baik untuk produksi bioetanol. Konversi selulosa (8,24%) dan produksi etanol (5,4%) tertinggi ditemukan pada beaten pulp yang difermentasikan dengan konsentrasi khamir 15% dan waktu inkubasi 3 hari. Perlakuan beating diasumsikan dapat meningkatkan rendemen etanol, namun demikian, bahan kimia dan mineral aditif pada kertas menghambat proses hidrolisis enzimatik dan tinta menghambat fermentasi gula sederhana.Kata kunci:bioetanol, pulp putih, penggilingan, kertas bercetak laser,SSF

Abstract

Eco-friendly renewable energy such as wood pellet is necessary to replace fossil fuels. Hence, the wood pellet industry has been rapidly developed, particularly, in European and America countries. To capitalize a high demand of wood pellet in those countries, Indonesia’s wood pellet companies need analysis tools to make decision on management and operation of their wood pellet production such as productivity, efficiency, production cost and and profitability assessments. The objectives of this study were to analyze cost, break-event point and profitability of wood pellet production. This study was conducted at a large integrated wood based panel and wood working products company, which produces wood pellet from its forest products residues. The results showed that the production cost was about IDR 1.41 millions per ton or US$ 114 per ton. The break-even point was about 1400 tons per year or about 84.7% of actual production. The return on investment (ROI) was about 14.15 %, which was slightly higer than a lending rate of 10.25%.Key words: energy, production cost, profitability, wood pellet, wood residues

Abstract

The availability of fossil energy resources as an input of production is limited and eventually will be rare. One of potential alternative energy that is recently developed to partly substitute fossil fuels based energy is wood pellet. The objective of this research was to analyze the levelized cost of energy (LCoE) of wood pellet made from wood processing residues. LCoE was the minimum energy prices that should be sold for an energy project to break even. The LCoE of wood pelet was obtained about IDR 259 per kWh or USD 0.02 per kWh. This LCoE value is lower than the LCoE of fossil fuels. It is indicating that energy derived from wood pellet is a very competitive.Keywords: LCoE, renewable energy, wood pellet, wood industry, wood residues
