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

Edamame cultivation on alluvial soils in West Kalimantan faces persistent challenges related to poor soil quality, including low organic matter content, compacted structure, and limited nutrient retention capacity. This study evaluated the effectiveness of compost-biochar amendment to enhance soil properties and edamame growth on alluvial soil. A completely randomized design with 13 treatments in triplicates was employed, combining compost biochar doses (5, 10, and 15 ton/ha) with varying NPK fertilizer reduction levels (0%, 25%, 50%, and 75%). Compost consisted of water hyacinth compost and rice husk biochar mixed at 1:1 ratio (v/v), applied one week before planting. Results demonstrated significant improvements in both vegetative growth and soil chemical properties (p<0.05). The treatment combining 15 ton/ha compost with 25% NPK (C12) produced the highest number of branches (7.67) and trifoliate leaves (25.50), representing increases of 109% and 63% respectively over the control. Application of 10 ton/ha compost with 50% NPK reduction (C8) optimally enhanced soil organic carbon to 1.90% and water retention to 37.61%, demonstrating 46% and 7.2% improvements over untreated soil. These findings indicate that compost–biochar amendment can substantially improve soil quality while maintaining edamame growth under reduced NPK input. A reduction of up to 50% of NPK fertilizer is achievable without compromising soil improvement and plant performance, highlighting the potential of this approach for sustainable edamame production on alluvial soils.

Abstract

This community engagement program was initiated in response to the underutilization of water hyacinth by the Maju Jaya Women Farmers Group (KWT Maju Jaya) in Parit Keladi Village as a raw material for economically valuable products. The main challenges faced by the partner group included limited technical knowledge of humic acid production and insufficient understanding of green branding for the development and commercialization of eco-friendly products. The program aimed to introduce fermentation technology using Effective Microorganisms (EM-4) for the production of liquid humic acid and to develop a green brand identity to support product marketing. The implementation methods comprised awareness sessions on the business potential of eco-friendly products, practical training in humic acid production, and training on the development of a green brand identity, with KWT Maju Jaya actively involved as the community partner. Evaluation results demonstrated a substantial improvement in participants’ understanding of humic acid production, increasing from an average of 1.7% before the intervention to 85.4% after the intervention, with an N-Gain score of 0.85, categorized as high. Similarly, participants’ understanding of green branding increased from an average of 0.8% to 86.7%, with an N-Gain score of 0.87, also categorized as high. Overall, the program strengthened the partner group’s production and marketing capacities, contributed to reducing aquatic environmental pollution through the productive utilization of water hyacinth, and created opportunities for additional income generation beyond conventional rice farming activities.
