Abstract

The purpose of this study is to analyze: The production capacity of women who carry out activities of processing agricultural products made from soybeans and the personal characteristics that influence them in the city of Mataram. Three sub-districts with a total of 6 sub-districts were selected as locations for data collection, namely Sandubaya sub-district (Abian Badan Baru Village area), Sekarbela (Karang Pule and Kekalik Jaya Sub-district areas), and Selaparang (Monjok and Monjok Timur Sub-Districts) considering the large number of processing businesses with raw materials. soya bean. A total of 60 respondents were interviewed using a survey approach to obtain information. The data obtained was then processed using both descriptive and inferential statistics using Pearson's correlation, and different ANOVA testing. The results of data processing indicate that the business capacity of women who carry out production activities of soybean-based agricultural products is included in the very high class, and the factors that are thought to influence women's ability to process soybean-based agricultural products in this study are personal characteristics: non-formal education, length of business, motivation to try, access to information, participation in groups).

Abstract

The utilization of non-wood biomass residues as alternative solid fuels is important for supporting low-carbon energy transitions and circular bioenergy development. This study evaluated the quality and energy performance of charcoal briquettes produced from vegetative residues of sugar palm (Arenga pinnata), specifically fronds, fruit stalks, and a mixture of both materials. A completely randomized design was applied, and the briquettes were assessed based on physical properties, proximate composition, combustion performance, and charcoal yield, with SNI 01-6235-2000 used as the primary quality benchmark. The results showed that all briquette types had very low moisture content (1.69–2.03%) and high calorific values (5,427–5,985 cal g⁻¹), meeting the SNI requirements for these parameters. Significant differences among plant parts were observed in ash content, volatile matter, and fixed carbon content (p < 0.05), indicating that raw material characteristics strongly influenced briquette quality. Briquettes produced from sugar palm fronds exhibited the highest fixed carbon content and calorific value, as well as the lowest burning rate, reflecting better thermal stability and longer combustion duration. Meanwhile, briquettes made from the mixture of fronds and fruit stalks showed the lowest ash content and the most balanced quality profile. Although some proximate parameters, particularly volatile matter and fixed carbon, did not fully meet the SNI limits, these limitations are process-dependent and may be improved through optimization of carbonization conditions. Overall, sugar palm vegetative residues represent a promising non-wood biomass resource for sustainable charcoal briquette production within a circular bioenergy framework.
