Abstract

Kegiatan magang dilaksanakan di PT Energi Agro Nusantara (EAN), yang merupakan perusahaan di bidang energi terbarukan dengan produk utama bioetanol berbahan baku molases. Selama pelaksanaan magang, mahasiswa mempelajari proses produksi bioetanol secara menyeluruh yang meliputi persiapan bahan baku, fermentasi, refinery, sistem utilitas, pengendalian mutu, pengolahan limbah, serta penerapan keselamatan dan kesehatan kerja (K3). Selain itu, mahasiswa menyusun neraca massa dan neraca energi pada unit fermentasi dan refinery, membuat Process Block Diagram (PBD), Process Flow Diagram (PFD), dan Piping and Instrumentation Diagram (P&ID), serta melakukan identifikasi potensi bahaya menggunakan metode Hazard and Operability Study (HAZOP). Permasalahan utama yang dikaji dalam kegiatan magang adalah analisis faktor-faktor yang memengaruhi konsentrasi impuritas pada proses redistilasi melalui simulasi menggunakan perangkat lunak Aspen HYSYS. Analisis dilakukan dengan mengevaluasi pengaruh efisiensi tray, lokasi umpan (feed), bottom rate, tekanan operasi, laju alir uap (steam), dan laju alir umpan terhadap kualitas bioetanol yang dihasilkan. Hasil analisis menunjukkan bahwa pengaturan kondisi operasi dan optimasi parameter proses berpengaruh signifikan terhadap efisiensi pemisahan, penurunan konsentrasi impuritas, peningkatan kemurnian bioetanol, serta kestabilan proses produksi.

The internship was conducted at PT Energi Agro Nusantara (EAN), a renewable energy company specializing in the production of bioethanol from molasses. During the internship, the student gained comprehensive knowledge of the bioethanol production process, including raw material preparation, fermentation, refinery operations, utility systems, quality control, wastewater treatment, and the implementation of Occupational Health and Safety (OHS). In addition, the student performed mass and energy balance calculations for the fermentation and refinery units, developed a Process Block Diagram (PBD), Process Flow Diagram (PFD), and Piping and Instrumentation Diagram (P&ID), and conducted hazard identification using the Hazard and Operability Study (HAZOP) method. The main issue investigated during the internship was the analysis of factors affecting impurity concentration in the redistillation process through process simulation using Aspen HYSYS software. The analysis evaluated the effects of tray efficiency, feed location, bottom rate, operating pressure, steam flow rate, and feed flow rate on the quality of the produced bioethanol. The results indicated that appropriate operating conditions and process parameter optimization significantly improved separation efficiency, reduced impurity concentration, enhanced bioethanol purity, and maintained process stability.
