Pengaruh Waktu Distilasi Etanol-Air Terhadap Konsentrasi Overhead Product dan Bottom Product

Nur Ihda Farikhatin Nisa, Achmad Aminudin

Abstract

Bioetanol merupakan salah satu energi terbarukan yang dapat diproduksi dari berbagai bahan seperti sorgum, tebu atau bahkan substrat dari limbah industri makanan. Pembuatan bioetanol melibatkan proses distilasi. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh lamanya waktu distilasi etanol-air terhadap konsentrasi overhead product dan bottom product yang keluar dari kolom distilasi. Metode dalam penelitian ini terdiri dari tahap persiapan, distilasi dan tahap analisa. Konsentrasi etanol ditentukan melalui pengukuran indeks bias menggunakan refraktometer. Dari hasil penelitian yang telah dilakukan dapat disimpulkan bahwa semakin besar indeks bias larutan etanol maka semakin besar konsentrasi larutan. Semakin lama waktu distilasi maka konsentrasi overhead product semakin besar. Hal ini berbanding terbalik dengan konsentrasi larutan di bottom product yang semakin kecil dengan bertambahnya waktu distilasi.
