Bioconversion of Rice Snails into Liquid Organic Fertilizer in Tanjung Perangat

Biokonversi Siput Sawah menjadi Pupuk Organik Cair di Tanjung Perangat

Abstract

The Community Service Program in Tanjung Perangat Village developed a liquid organic fertilizer (LOF) prototype through the bioconversion of rice-snail biomass and locally available organic residues. This community-engagement article analyzes the technical rationale of the formulation, the implementation sequence, the quality of evidence generated by the program, and the requirements for transforming a demonstration product into a reproducible community-scale practice. Activities were conducted from July 5 to 29, 2026, and culminated in a socialization and demonstration session attended by 32 residents representing village authorities, neighborhood leaders, farmer groups, the farmers' group association, and landholders. The pilot formulation combined rice-snail biomass, banana peel, rice-washing water, water, and EM4, with a reported 14-day fermentation target and a 1:10 LOF-to-water dilution for trial application. Program documentation confirms knowledge transfer, product demonstration, trial application, and sample distribution. Scientific appraisal indicates that Pomacea canaliculata is an invasive rice pest and that organic residues can be recycled as nutrient sources; however, fertilizer quality depends on feedstock composition, microbial transformation, maturity, nutrient balance, contaminant control, and crop-specific dosage. The program did not include laboratory analysis of pH, electrical conductivity, organic carbon, N, P, K, microbiological safety, storage stability, or controlled agronomic trials. Consequently, this article does not claim agronomic efficacy or compliance with fertilizer quality standards. Further development requires standardized batch records, laboratory verification, safety assessment, controlled dose-response trials, and participatory adoption evaluation with farmer groups.
