Abstract
Fuel or energy sources scarcity is currently a problem in Indonesia. Pine waste and peanut shells are wastes that have potential to be processed into alternative energy as briquettes, using molasses as adhesive. Briquette was made by destroying the material into small pieces that have been carbonized and sieved with a variation of 20 and 30 mesh size, added with molasses, and then molded with a hydraulic press. Briquettes are dried using an oven at 105 °C for 10 hours to remove moisture content. The pine to peanut shell ratio used are of 0:1, 1:0, 1:1, 1:2, 1:3, 2:1, 2:3, 3:1 and 3:2. The analysis includes analysis of calorific value, moisture content, ash content and compressive strength. The result shows the pine waste to peanut shells ratio of 1:0 has the highest calorific value for 20 mesh is 4674.50 Cal/g and for 30 mesh is 4585.10 Cal/g. The lowest water content for 20 mesh is 1.76% and for 30 mesh is 1.85%. The lowest ash content for 20 mesh is 0.58% and for 30 mesh is 0.59%. And the highest compressive strength for 20 mesh is 35.20 kg/cm2 and for 30 mesh is 28.90 kg/cm2.
Highlights
One of the big problems faced by Indonesia today is the scarcity of energy fuel, which become emergently crucial due to the raise of population in Indonesia
The agricultural waste can be processed into an artificial solid fuel that is used as a substitute for alternative fuels called briquettes
This study was aimed to examine the effect of raw materials for waste pine fruit and peanut shells on moisture content, ash content, calorific value and compressive strength produced by briquettes
Summary
One of the big problems faced by Indonesia today is the scarcity of energy fuel, which become emergently crucial due to the raise of population in Indonesia. The more depleted the amount of fossil fuels, the impact is starting to be felt nowadays, as a can be seen the amount of kerosene is getting limited. For this reason, renewable energy sources are needed in providing sustainable energy sources. Renewable energy sources are needed in providing sustainable energy sources This will be even more so if the raw materials for alternative energy sources come from waste, so that it can reduce production costs and reduce the negative effects of waste accumulation on the environment [1]. Making briquettes with different compositions of mixed materials (agricultural waste) will affect the absorption of water content, ash content and the quality of the resulting calorific value [2]
