Abstract

Permintaan bioetanol sebagai pelarut industri food grade terus meningkat seiring dengan program transisi energi dan pertumbuhan sektor industri di Indonesia. Laporan ini bertujuan untuk merancang pabrik bioetanol dengan kadar kemurnian 99,5% menggunakan bahan baku nira batang sweet sorghum (Sorghum bicolor), yang memiliki keunggulan berupa kandungan gula yang tinggi, umur panen pendek, serta kebutuhan air yang relatif rendah. Proses produksi utama meliputi tahap pre-treatment, fermentasi menggunakan mikroorganisme Saccharomyces cerevisiae, distilasi bertingkat, serta dehidrasi menggunakan teknologi adsorpsi berbasis molecular sieve untuk mencapai kemurnian etanol sesuai standar food grade. Lokasi pabrik direncanakan di Kabupaten Flores Timur, Nusa Tenggara Timur, dengan mempertimbangkan ketersediaan bahan baku, akses transportasi, potensi sumber daya alam, serta dukungan terhadap pengembangan wilayah timur Indonesia. Kapasitas produksi dirancang sebesar 20.000 kL per tahun dengan waktu operasional 330 hari kerja. Berdasarkan analisis kelayakan ekonomi, diperoleh nilai IRR sebesar 22,4 %, NPV sebesar Rp 170.782.938.378,26, pay out time selama 5,59 tahun, dan BEP sebesar 41,39 %, yang menunjukkan bahwa proyek ini layak untuk direalisasikan. Pabrik juga dirancang sesuai standar keamanan pangan dan lingkungan seperti HACCP, SNI, dan FCC, guna menjamin mutu produk serta keberlanjutan operasional. Proyek ini diharapkan dapat berkontribusi dalam substitusi impor etanol dan mendukung kemandirian energi nasional.

The demand for food-grade industrial ethanol continues to increase in line with Indonesia's energy transition program and industrial growth. This study aims to design a bioethanol plant with 99.5% purity using sweet sorghum stem juice (Sorghum bicolor) as the raw material, which offers advantages such as high sugar content, short harvest period, and low water requirements. The main production process includes pre-treatment, fermentation using Saccharomyces cerevisiae, multi-stage distillation, and dehydration using adsorption technology based on molecular sieve to achieve ethanol purity that meets food-grade standards. The plant is planned to be located in Flores Timur Regency, East Nusa Tenggara, considering the availability of raw materials, transportation access, natural resource potential, and support for regional development in Eastern Indonesia. The production capacity is designed at 20,000 kL per year with 330 operating days annually. Based on the economic feasibility analysis, the project yields an IRR of 22.4 %, NPV of IDR 170.782.938.378,26, a payback period of 5.59 years, and a BEP of 41.39%, indicating that the project is economically viable. The plant is also designed to comply with food safety and environmental standards such as HACCP, SNI, and FCC to ensure product quality and sustainable operations. This project is expected to contribute to reducing ethanol imports and strengthening national energy self-sufficiency.
