Abstract

This study aims to determine the combustion rate and heating value of rice husk wafer briquettes with variations in pressure. The manufacturing process uses briquette press, the ingredients used are rice husk and starch. The results of the density of rice husk wafer briquettes with a sequence of 20 PSI pressure variations in the amount of 0.453 g/cm3, 30 PSI in the amount of 0.467 g/cm3, and 40 PSI in the amount of 0.500 g/cm3. The calorie value of rice husk wafer briquettes with a variety of sequential pressure variations of 20 PSI is 4,793.94 calories, 30 PSI is 5,137.64 calories, 40 PSI is 5,266.52 calories. The resulting water content with a variety of pressures in sequence 20 PSI is 6.45%, 30 PSI is 6.40 %, 40 PSI is 5.65%. The value of the rate of burning of rice husk wafer briquettes in sequence of 20 PSI is 2.22212 grams / minute, 30 PSI is 2.22878 grams / minute, 40 PSI is 2.4363 grams / minute fault. It can be concluded that the greater the pressure, the calorific value and the rate of combustion of rice husk wafer briquettes will increase.
