Abstract

The use of Ultisol soil for agriculture has problems, namely low soil organic matter and acidity. This can be overcome by adding organic matter to the soil to act as an ameliorant. The ameliorant can be applied by utilizing coconut waste that has been processed into bioactive compost charcoal. Bioactive compost charcoal is a mixture of charcoal (biochar) and compost composted using Trichoderma harzianum. This study aims to determine the effect of bioactive compost charcoal and incubation period on soybean growth in Ultisol soil. This study used a completely randomized design (CRD) factorial pattern, consisting of two treatment factors. The first factor was bioactive compost charcoal with 4 levels (0; 5; 10; 15 tons ha⁻¹) and the second factor was incubation period with 3 levels (0; 2; 4 weeks). Each treatment was repeated 3 times, consisting of 3 plants, for a total of 108 plants. The results of this study showed that a dose of 15 tons ha⁻¹ of bioactive compost charcoal significantly increased plant height (46,05 cm), number of leaves (55,19 leaves), root volume (7,44 cm³), and plant dry weight (14,40 g), while a dose of 10 tons ha⁻¹ resulted in the highest number of soybean branches (5,37 branches) in Ultisol soil.

Abstract

Farmer poverty and food insecurity are key social determinants that directly affect community health status. Sungai Betung Sub-district, Bengkayang Regency, has substantial agricultural potential that remains underutilized, resulting in low farmer income, food insecurity, and elevated health risks from chemical pesticide exposure among farmers and their families. This community service program aimed to improve farmer community health through empowerment in organic-based hybrid maize cultivation. Methods included community health education, practical organic farming training (organic fertilizer and Local Microorganism/MOL production), technical field mentoring, and market access facilitation to support income improvement and household food security. The four-month program (March–June 2025) involved 9 students, and the Agricultural Extension Center (BPP). Results demonstrated an average knowledge increase of 51.6% across six measured health domains, enhanced nutritious food production capacity, and established marketing partnerships that support household income improvement. This program affirms that organic-based agricultural empowerment is an effective promotive-preventive strategy for improving rural community health status.
