Abstract

The village of Muara Sikabaluan in the Mentawai Islands faces various challenges in education, economy, and the environment. A community empowerment program based on the circular economy has been implemented to enhance the capacity for processing agricultural and marine products, such as bananas, taro, cassava, and fish. Training in product processing and online and offline marketing was provided to improve the knowledge and skills of residents, especially housewives. The program also promotes the establishment of a village business and economic center as a hub for business development and community welfare improvement. Pretest and posttest results showed significant increases in residents' knowledge and skills related to product processing and the application of circular economy principles. With a participatory and sustainable approach, Muara Sikabaluan Village is expected to become a model for sustainable village development.

Abstract

Improving rice productivity is a key priority to meet the increasing national food demand. This study aims to examine the effect of ecoenzyme addition to a Trichoderma asperellum-based corn medium on the biomass of rice seedlings of the Bujang Marantau variety. The research was conducted using a Completely Randomized Design (CRD) with five ecoenzyme concentration treatments (0%, 20%, 40%, 60%, and 80%) and five replications. Parameters observed were fresh weight and dry weight of seedlings after 14 days of treatment. Data were analyzed using ANOVA at a 5% significance level and followed by Duncan’s New Multiple Range Test (DNMRT). The results showed that ecoenzyme application did not significantly affect the fresh or dry weight of the rice seedlings. The highest fresh weight was found at 20% concentration, while the highest dry weight was at 80%. It is concluded that ecoenzyme has not demonstrated effectiveness in enhancing seedling biomass during the early growth stage, possibly because seedlings still rely on internal food reserves. The findings suggest that ecoenzyme may be more suitable for improving soil quality rather than directly stimulating early plant growth. Further research is recommended to optimize dosage, application methods, and appropriate growth stages for maximum benefit.
