Abstract

Hermeneutics as an object of study is a means of understanding the ”actual” as old as human beings age on this earth. Hermeneutics is very important in the process of human interaction, so the study was conducted to study the hermeneutics in his position as a science of interpretation that can be studied in ontological, epistemological, and axiological. As a science, hermeneutics emerged as a dominant movement in European Protestant theology which states that hermeneutics is a focal point of the current theological issues. Associated with his position as a science, the study was conducted to determine hermeneutics in the concept of etymology and terminology, knowing on historically with the figures who pioneered the science of it, his position as a theory of interpretation multidisciplinary, as well as the position and function as a historiographical approach through philological approach. Keywords: hermeneutics, the theory of interpretation, and text.

Abstract

Produksi etanol dilakukan dengan beberapa perlakuan antara lain pengenceran larutan stok menjadi 4 variasi konsentrasi, penambahan nutrisi, pengaturan pH, sterilisasi bahan, pendinginan, penambahan inokulum Saccharomyces cerevisiae. Penelitian ini bertujuan mengoptimalisasi pemanfaatan fermentor dan Gas Chromatography untuk fermentasi etanol dan analisis hasilnya. Fermentasi dilakukan selama 96 jam dan pengambilan sampel dilakukan setiap 24 jam. Pengujian hasil fermentasi dilakukan dengan cara melakukan uji kadar alkohol metode conway, uji kadar alkohol metode GC setelah dilakukan pemekatan 5 kali dengan cara destilasi, uji gula dengan metode DNS untuk mengetahui sisa gula yang digunakan dalam fermentasi, uji TPC dan kekeruhan untuk mengetahui pertumbuhan sel Saccharomyces cerevisiae. Hasil uji dibuat grafik dan dianalisis menggunakan SPSS untuk mengetahui penambahan kadar alkohol tiap jam fermentasi, untuk mengetahui apakah data dianggap linier secara statistik dan untuk mengetahui berapa waktu optimal produksi etanol dengan kadar tertinggi. Hasil menunjukkan waktu optimal pemanfaatan fermentor adalah 72 jam dengan kemurnian etanol tertinggi 43,44%.
