Abstract

This study investigated the effectiveness of artificial shelter structures (rumpon) in reducing cannibalism and improving the survival rate of baung fish (Mystus nemurus) fry cultured in circular ponds. Cannibalism is one of the major constraints in baung fish hatchery production because it significantly decreases fry survival and productivity. A Completely Randomized Design (CRD) consisting of four treatments, namely control (without rumpon), full rumpon, ¾ rumpon, and ½ rumpon, with three replications for each treatment was applied. Parameters observed included survival rate and water quality (temperature, pH, and dissolved oxygen). Data were analyzed using analysis of variance (ANOVA), while water quality parameters were analyzed descriptively. The results showed that the full rumpon treatment produced the highest survival rate (56%), followed by ½ rumpon (50%), ¾ rumpon (45%), and control (13%). The presence of rumpon increased habitat complexity, reduced direct interactions among fry, minimized cannibalistic behavior, and consequently improved survival. This study demonstrates that coconut leaf rumpon can serve as a simple, environmentally friendly, and low-cost habitat modification technology to enhance baung fish hatchery performance.

Abstract

Modern agriculture faces increasing challenges from soil-borne fungal pathogens such as Fusarium oxysporum, Rhizoctonia solani, and Sclerotium rolfsii, which cause severe root and wilt diseases and significantly reduce crop productivity. This study employed a qualitative–descriptive approach supported by controlled laboratory experiments to evaluate the potential of agricultural waste as an alternative, low-cost substrate for producing antifungal rhizobacterial biopesticides. Six types of agricultural waste—rice straw, rice husk, corn cob, sugarcane bagasse, coffee husk, and soybean residue—were assessed based on their C/N ratio, lignin content, biodegradability, and nutrient availability. The results indicated that substrates with moderate C/N ratios (15–25) and low lignin content, particularly soybean residue and sugarcane bagasse, promoted optimal rhizobacterial colonization, robust biofilm formation, and high production of antifungal metabolites such as chitinase and siderophores. Rhizobacteria cultured on soybean residue exhibited the strongest inhibition zone against Fusarium oxysporum (20.5 mm) and the highest plant protection efficacy (88%), with biopesticide stability maintained for up to 120 days. Two conceptual models, Substrate Structure Colonization (SSC) and Media Metabolite Effectiveness (MME), are proposed to explain the relationship between substrate structure, metabolite biosynthesis, and biopesticide performance. These findings provide a sustainable strategy for converting agricultural waste into high-value bio-based inputs, supporting circular economy practices and green agriculture initiatives.
