Abstract

Laporan magang ini mengevaluasi proses produksi bioetanol berbasis molase di PT Energi Agro Nusantara, dengan fokus pada unit fermentasi dan pemurnian (refinery). Selain pemahaman operasional, laporan ini membahas troubleshooting pengaruh kualitas bahan baku, khususnya Total Sugar (TS) dan Volatile Acidity (VA), terhadap efisiensi konversi etanol. Analisis menunjukkan bahwa kadar TS yang lebih tinggi menurunkan rasio konsumsi molase, yang menandakan efisiensi konversi yang lebih baik. Sebaliknya, kadar VA yang tinggi berpotensi menghambat aktivitas ragi, sehingga diperlukan optimalisasi kondisi operasi seperti pH dan suhu. Evaluasi teknis mencakup perhitungan neraca massa, neraca energi, serta identifikasi risiko melalui metode HAZOP pada unit produksi. Laporan ini merekomendasikan pengendalian parameter fermentasi yang ketat untuk menjaga stabilitas yield etanol di tengah variasi kualitas bahan baku.

This internship report evaluates the molasses-based bioethanol production process at PT Energi Agro Nusantara, focusing on fermentation and refinery units. Beyond operational oversight, it addresses troubleshooting the impact of raw material quality—specifically Total Sugar (TS) and Volatile Acidity (VA)—on ethanol conversion efficiency. Analysis demonstrates that higher TS levels decrease the molasses consumption ratio, indicating improved conversion efficiency. Conversely, high VA can inhibit yeast activity, requiring optimized operating conditions such as pH and temperature. Technical evaluations include mass and energy balance calculations, along with hazard identification using the HAZOP method for production units. The report recommends strict control of fermentation parameters to ensure stable ethanol yields amidst raw material quality variations
