Abstract

The population growth in Indonesia from 270 million in 2020 to 279 million in 2024 has increased LPG consumption, potentially leading to future fuel shortages. The top-lit updraft (TLUD) gasifier stove using renewable biomass materials, offers a sustainable alternative. Biomass such as bagasse and sugarcane peel can be optimized into charcoal briquettes with high calorific value and low emissions. The calorific value of briquettes can be further enhanced by blending other high–calorific biomass materials. This experimental research focuses on testing the calorific value of raw bagasse and sugarcane peel before carbonization, as well as briquette mixtures (70:30, 50:50, 30:70) using a bomb calorimeter. The fuel briquettes are tested by operating the TLUD gasifier stove, measuring performance in terms of water boiling time (WBT) and flame characteristics. Results show that the 30:70 bagasse-to-sugarcane peel composition has the highest calorific value (6,242.292 cal/gram), followed by the 70:30 composition (6,094.753 cal/gram) and the 50:50 composition (5,657.935 cal/gram). The 30:70 ratio also achieved the longest flame duration (119 minutes 32 seconds), the highest combustion chamber temperature (570.2°C), and the greatest flame height (11.468 cm). The TLUD stove demonstrated an efficiency of 56.41%, with a char weight of 61 grams and a water temperature increase from 28.4°C to 90.4°C in 10 minutes 45 seconds. These briquettes met the SNI 01-6235-2000 standard, which requires a minimum calorific value of 5000 cal/g.

Abstract

Dependence on fossil fuels causes significant environmental damage and increases costs and scarcity in the future. To overcome this problem, a transition to renewable energy is needed, one of which is biodiesel which can be obtained from used cooking oil. This study aims to convert used cooking oil that cannot be reused into biodiesel products. Biodiesel synthesis can be carried out by the transesterification process, using NaOH catalyst with concentration variations of 0.5%, 0.75%, 1%, 1.25%, and 1.5% of the total mass of oil. The test parameters are calorific value, density, viscosity and flash point as well as yield on used cooking oil biodiesel products. The test results show that the use of a catalyst concentration of 1% produces more optimal density, viscosity, and calorific value and flash point. Each value is 0.859 g / cm³, 2.34 cSt, 10,356 cal / g, and 139°C. However, the use of a catalyst concentration of 0.5% shows that the biodiesel product is less than optimal. This can be shown by the highest density, viscosity and flash point values of the catalyst concentration variations used. Each value is 0.88 g/cm3, 3.16 cSt and 178°C, while the calorific value is also low with a value of 9,689 cal/g. However, when viewed from the yield, the catalyst concentration of 0.5% produces the highest value of all catalyst concentration variations used with a value of 88%.
