Rancang Bangun Alat Destilasi Sederhana Untuk Memenuhi Kebutuhan Akuades Di Laboratorium Teknologi Rekayasa Pangan

Abstract

The purpose of this research is to make a simple distillation apparatus to supply the needs of aquades in practicum and research at the Food Engineering Technology Laboratory. A simple distillation consists of several components, namely a pressure gauge, a safety valve, a place for input of water to be distilled, a round thermometer, a connecting pipe for the distillation column and the condenser, the distillation column, the cooling water column, the distillate water storage column, the condenser, the thermostat, the cooling water circulation hose, output and input valves, and drive wheels. A simple distillation also utilizes a source of electric power. The distillate water quality test that has been carried out based on the pH test, TDS test and DHL test results in a value that represents the demineralized water quality standard (according to SNI). Based on the analysis of operational costs to produce 1 L of distilled water is Rp. 734.12 and when compared to the price of distilled water in the market, it is Rp. 5000, - per L, the cost of purchasing aquades can be as much as 85.32% more efficient.
