Abstract

This community service program aims to improve the understanding and skills of the Kelompok Tani Mulyo (Mulyo Farmer Group) in processing dragon fruit stem waste into an alternative poultry feed. The method employed was a community empowerment-based training approach, which included stages of observation, implementation, and evaluation. The evaluation instruments consisted of pre-test and post-test questionnaires, which were analyzed using a descriptive comparative technique to measure the improvement in partners’ knowledge and skills. The results of this program showed an increase in participants’ technical understanding of waste processing from 41.5% to 100%. Most participants who initially hesitated or lacked understanding of the processing techniques are now capable of independently producing feed. This improvement demonstrates that the training was effective in transferring knowledge and skills, providing a concrete solution for waste management and promoting product diversification through the creation of additional livestock feed.

Abstract

The quality of biomass briquettes is largely determined by the type of raw material and the manufacturing process, especially in efforts to develop waste-based alternative fuels. This research analyzes the effect of the combination of coconut shells with cassava skins and corn husks on the physical properties and burning rate of briquettes using tapioca flour adhesive. Test results show that variations in biomass produce significantly different combustion characteristics. Cassava husk–coconut shell based briquettes showed a higher combustion rate (0.24 g/minute), while corn husk–coconut shell briquettes produced more stable combustion with a lower rate (0.17 g/minute). Even though the water content of the two briquettes is still within acceptable limits, the high ash content (>25%) is the main limiting factor because it does not meet the SNI 01-6235-2000 standard and has the potential to reduce energy efficiency. These findings confirm that the selection of biomass type and control of the carbonization process play a crucial role in determining the performance of briquettes. Optimizing production parameters is needed so that agricultural waste-based biomass briquettes can be developed as an alternative fuel that meets national quality standards and supports a sustainable energy transition.
