Abstract

Biomass, such as wood waste, is one of the resources that can be potentially converted into a carbon product for catalyst applications. In this study, the sulfonated carbon was obtained through the pyrolysis method for wood waste at the temperature of 350°C, which was later sulfonated through the use of  H2SO4 (8N) on the reflux for 4 h. The sulfonated carbon was then analyzed and characterized including its water content, ash content, volatile matter, fixed carbon, iodine adsorption as well as the H+ (acidity) capacity using ammonia adsorptions and functional groups and the Fourier Transform Infra-Red (FTIR) instrument. The catalyst application was carried out during the kempili pulp hydrolysis process using a microwave with the ratio of catalyst to a pulp of 1:1 (5g:5g), with the power conditions of 300, 400, and 600 watt for 3, 5, and 7 min. The results showed that the sulfonated carbon catalyst had water content, volatile matter, ash content, fixed carbon, iodine adsorption as well as the catalyst acidity as much as 3.48%; 11.70%; 4.21%; 84.62%; 690.88 mg/g; and 6.45 mmol/g, respectively with the highest glucose content of 160.83 ppm. The carbon-based catalyst is expected as an alternative catalyst, can be further developed for hydrolysis reactions, and can serve as a green technology product in the future.

Abstract

Understanding gender aspects in the management of small-scale agroforestry is important to creating an inclusive and sustainable model in subsistence agriculture. This research aimed to analyze the actualization of the gender dimension in productive, reproductive, and social-political activities in small-scale agroforestry management among subsistence farmer groups in Lamala Sub-District, Banggai Regency, Indonesia. The study employed a mixed-methods case study approach using the Harvard Analytical Framework (HAF) to analyze the gender-based division of labor, integrating observations, interviews with 5 key informants, and a questionnaire administered to 50 respondents. The data collected were then analyzed thematically and descriptively. The results showed a gender imbalance in the management of small-scale agroforestry. HAF mapping indicated that women were involved in only 52.63% of the identified productive activities, whereas men were involved in all productive activities. In contrast, women carried out all identified reproductive activities, while men were involved in only 33.33% of them and only occasionally. In socio-political activities, women were involved in 66.67% of the identified activities, again only occasionally, whereas men were involved in all activities and dominated 66.67% of them. These findings suggest that small-scale agroforestry is not gender-neutral, as its productive, reproductive, and socio-political activities are structured through unequal gender relations. This research recommends education for small-scale farmers on gender and productivity, helping the community understand gender equality in efforts to improve access, productivity, and outcomes through equitable, egalitarian role distribution.
