Abstract

This study aims to evaluate the potential of organic liquid fertilizers (LOF) derived from agricultural, plantation, and animal waste in Mamuju Tengah District, employing an ecodesign approach. The LOF materials used were goat urine, palm fruit leaf, rice straw, and corn straw. The research methodology employed was a randomized complete block design with four LOF treatment doses: a control (K), 10 ml, 20 ml, and 30 ml per liter of water. Each treatment was replicated four times and applied to two plant species: elephant grass (Pennisetum purpureum) and the legume Indigofera. The parameters observed included plant height, number of tillers, chlorophyll content, and the number of nodules on the roots of the plants. The study results indicate that LOF does not significantly affect plant height in either test species. However, a significant effect was observed on increased chlorophyll content and the number of nodules in the Indigofera plants.  Furthermore, the application of LOF resulted in a notable impact on the number of seedlings and chlorophyll content in elephant grass. The findings of this study indicate that LOF, derived from agricultural, plantation, and animal by-products, benefits specific growth parameters, particularly chlorophyll and nodules. This suggests that LOF has the potential to serve as an environmentally friendly fertilizer in sustainable agricultural systems.

Abstract

This study aimed to identify potential weed species suitable as raw materials for fermentation technology in producing nutrient-rich organic fertilizers, thereby linking sustainable agricultural innovation with Islamic environmental ethics. A Completely Randomized Design (CRD) was employed with four treatments based on the volume of fermented weed-based fertilizer (0, 30, 40, and 50 mL) and three replications, resulting in a total of 36 experimental units. Observed parameters included plant height, leaf area, and chlorophyll content, while forage quality was analyzed through neutral detergent fiber (NDF), acid detergent fiber (ADF), and acid detergent lignin (ADL) composition. Results showed that weed fermentation had no significant effect on plant growth (P > 0.05) but significantly improved forage quality (P < 0.01) across fertilizer doses. Fermented weed-based fertilizer thus proved effective for enhancing the nutrient quality of green fodder sustainably. This research introduces a novel integration of weed fermentation technology and Islamic ethical principles, providing an innovative model for eco-friendly and faith-aligned agricultural practices.
