THE UTILIZATION OF SAGO DUE WASTE AS AN ALTERNATIVE FUEL
Journal Title: Engineering and Technology Journal - Year 2022, Vol 7, Issue 09
Abstract
Sago is a native plant of Indonesia, with an area of about 1.128 million ha or 51.3% of the world's sago area. Potential areas for producing sago (Metroxylon sp.) in Indonesia include Riau, South Sulawesi, Southeast Sulawesi, North Sulawesi, Maluku and Papua, where about 90% of the sago area in Indonesia is in Papua. From studies conducted by non-governmental organizations (NGOs) such as WWF which in May 2014 conducted various studies on the utilization of agricultural wastes that can still be used as alternative energy sources, which of course must be studied further. The study must of course be tested in the laboratory. Studies in the laboratory involve ultimate testing based on chemical content tests and proximation studies (thermal properties of fuel). This study must be carried out with the aim of knowing whether the sample to be used as fuel is feasible or not. This research is to do laboratory testing to determine the chemical composition of briquettes, thermal properties. The 60, 80 mesh size briquettes are molded in a cylindrical shape. The results of printing sago dregs charcoal briquettes consist of 60 mesh and 80 mesh, where the two briquettes have the following dimensions for a grain size of 60 mesh, briquette diameter b = 44.90 mm = 4,490 cm, briquette mass = 0.17 gr, briquette height = 69.80 mm = 6.980 cm. Then for mesh 80, - Diameter of briquettes b = 44.90 mm = 4.490 cm, mass of briquettes = 220.078 gr, height of briquettes = 69.80 mm = 6.980 cm. The results of the proximate analysis test produce: for mesh 60, among others, moisture 13.08%,; volatile matters 26.18%,; fixed carbon 27.88%, and calorific value above 4013 kcal/kg, while for mesh 80, among others, moisture 13.36%; volatile matters 23.52%,; fixed carbon 29.86%, and the calorific value of 4007 kcal/kg. The density of mesh 80 is 2,769 gr/cm3, mesh 60 is 1,998 gr/cm3, the combustion efficiency of mesh 60 is 5.070% and mesh 80 is 3.58%.
