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

Alkaline Fuel Cell (AFC) is a green energy conversion tool that converts chemical energy into electrical energy through electrochemical reactions. This research aims to analyze the effect of potassium hydroxide (KOH) concentration variation in electrolyte solution on the AFC performance, using nickel and manganese catalysts. The research methods include experiments using various KOH concentrations to determine the optimal concentration to produce the best AFC performance. The voltage and current produced are measured, as well as the calculation of the electrical power and efficiency of the AFC. The results showed that KOH concentration has a significant influence on the performance of AFC. It was found that the optimal KOH concentration produces maximum electrical power and energy conversion efficiency. The highest alkaline fuel cell performance was found at 70% KOH concentration. In addition, the use of nickel and manganese catalysts was shown to improve the stability and efficiency of AFC. The result makes an important contribution to the development of AFC technology, supporting global efforts towards cleaner and more sustainable energy use. The findings also provide a basis for further innovations in AFC design and materials, as well as their potential in practical applications such as electric vehicles and portable power plants
