Abstract

The demand for fossil energy sources continues to increase, which causes scarcity of these resources because they cannot be renewed. In Indonesia, waste rice straw and rice husks are abundant and have potential as a renewable energy source if converted into charcoal briquettes. However, currently the charcoal briquettes produced have not reached the desired level of efficiency to replace fossil fuels. Therefore, research was carried out to develop biomass energy by mixing zeolite in charcoal briquettes. This research aims to develop charcoal briquettes as an energy source from biomass. In this study, the calorific value of charcoal briquettes from rice straw with a 25% zeolite mixture had the lowest calorific value, namely 3941.2 cal/gram, while charcoal briquettes from rice straw without a zeolite mixture had the highest calorific value, namely 4581.8 cal/gram . The same thing happened to charcoal briquettes from rice husks, with the highest calorific value in charcoal briquettes without a zeolite mixture of 5390.5 cal/gram, and the lowest calorific value in charcoal briquettes mixed with 25% zeolite of 4469.1 cal/gram. The density of rice straw charcoal briquettes with a 25% zeolite mixture has the highest density value, namely 0.338 g/cm3, while rice straw charcoal briquettes without a zeolite mixture have the lowest density, namely 0.199 g/cm3. Likewise, charcoal briquettes from rice husks have the highest density in a 25% zeolite mixture with a value of 0.545 g/cm3, and the lowest density in charcoal briquettes without a zeolite mixture is 0.284 g/cm3.

Abstract

Biomass is a type of solid waste that is used as an alternative energy source to replace fossil fuels (petroleum) because it can be renewed. Biopellets are a renewable fuel that comes from biomass. The aim of this research is to determine the characteristics of coconut waste biopellets. young with the addition of zeolite variations. The research method used is experimental research. The zeolite material used has 6 dosage variations, namely 0% (0 gram), 5% (2.5 grams), 10% (5 grams), 15% (7.5 grams) , 20% (10 grams), 25% (12.5 grams), with fixed variations from 50 grams of young coconut waste, tapioca flour adhesive and 20 grams of sugar cane molasses. The best burning rate of young coconut waste biopellets was obtained with the T 5 biopellet composition with a molasses adhesive composition with the addition of 5% zeolite with a value of 0.017% g/s. and the lowest water content value is found with the T 25 biopellet composition using molasses adhesive with a 25% zeolite mixture. And the best ash content value can be with P 0 biopellet composition using tapioca flour adhesive without zeolite mixture with a value of 3.32%.

Abstract

The aim of this research is to analyze the effect of remapping maximum engine speed with standard ECU variations and ECU remapping on the performance of a 110cc injection motorbike engine. In this research, dynotest testing was carried out on 110cc injection motorbikes of various types of standard Electronic Control Unit (ECU) and standard Electronic Control Unit (ECU) by taking test results at engine speeds of 3000 rpm-8000 rpm with a range of 1000 rpm. The calculation method is to calculate power and torque. The test results using a dynotest tool based on power and torque obtained data as above, where the highest power and torque from the standard ECU variable was obtained at 7.4 HP and the highest torque at 9.38 Nm. Meanwhile, using the standard ECU remap, the highest power is 7.6 hp and the highest torque is 9.52. The results of the dynotest test and also calculations from Origin Pro with a comparison using a standard ECU and a remap standard ECU concluded that the use of a remap standard ECU can provide an increase in power and torque in the motorbike engine. When using a standard ECU remap, the results show that the standard ECU that has been remapped actually provides higher improvement results than the standard ECU that has not been remapped.
