Destilasi Bioetanol dari Nira Aren dengan Variasi Waktu Pengadukan pada Proses Fermentasi

Abstract

Bioetanol merupakan salah satu jenis energi terbarukan yang dapat dimanfaatkan sebagai bahan bakar kendaraan bermotor menggantikan bensin dan pertalite. Bioetanol umumnya diperoleh dari produk-produk pertanian, baik yang berupa padatan seperti dari ubi-ubian atau produk cair seperti nira nipah atau nira aren. Produksi bioetanol umumnya dilakukan dengan metode destilasi dengan memanfaatkan perbedaan titik didih antara zat yang akan dipisahkan, dalam hal ini etanol dan air. Sebelum proses destilasi, bahan sumber bioetanol dilakukan proses fermentasi dengan bantuan ragi. Tujuan penelitian adalah untuk mengetahui kadar alkohol dari bioetanol yang dihasilkan dengan perbedaan waktu pengadukan selama fermentasi. Produksi bioetanol pada penelitian ini dilakukan melalui serangkaian tahapan kegiatan meliputi pasteurisasi, fermentasi, dan destilasi. Proses fermentasi bioetanol berlangsung selama 3 hari setelah proses pasteurisasi. Selama fermentasi, air nira diaduk dengan dua variasi waktu pengadukan yang berbeda, yaitu 3 menit dan 6 menit setiap 6 jam sekali. Adapun alat dan bahan yang digunakan dalam penelitian ini adalah alat destilasi, kompor gas, pH meter, termometer, alkohol meter, pompa air, air pendingin, nira aren, ragi dan gas LPG. Berdasarkan hasil pengujian diketahui bahwa semakin lama waktu pengadukan saat fermentasi dapat meningkatkan kadar alkohol dari bioetanol yang dihasilkan. Proses pengadukan selama 3 menit menghasilkan bioetanol dengan kadar alkohol 49%, sedangkan peningkatan waktu pengadukan menjadi 6 menit berkontribusi pada peningkatan kadar alkohol menjadi 55%. Dengan demikian, dapat disimpulkan bahwa waktu pengadukan saat fermentasi bioetanol memiliki peran dalam peningkatan kualitas etanol yang dihasilkan.
