Abstract

Purpose: The study aimed to examine the quality of vermicompost produced through the combination of oyster mushroom Baglogs and pineapple waste using the Eudrillus eugeniae species as a decomposer.

Method: Vermicompost and compost were derived from a mixture of oyster mushroom Baglogs and pineapple waste. Eudrillus eugeniae earthworms were employed as the decomposers for the vermicomposting process. Vermicompost, compost, and the initial substrate were analyzed using Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), Particle Size Analyzer (PSA), chemical composition analysis, and microbiological analysis.

Results: The FT-IR spectra of the vermicompost confirmed an increase in nitrogen-rich compounds and the presence of humic substances. SEM analysis revealed more significant morphological structure changes in vermicompost.  Furthermore, the vermicompost showed the smallest particle size (95.85 µm) compared to compost (149.73 µm) and the initial substrate (653.31 µm). The vermicompost demonstrated a 3-fold reduction in C/N ratio compared to the initial substrate. The nutrient content of the vermicompost increased by 1.2 – 3.2-fold from the initial substrate. The vermicompost exhibited a higher bacterial population (30.93x107 CFU/g) compared to compost (10.05x107 CFU/g) and initial raw material (2.47x107 CFU/g).

Conclusion: The results demonstrated improvement in the qualities of vermicomposting as a sustainable method for waste recycling. The enhanced nutrient content, particle size reduction, and increased bacterial population in the vermicompost indicated its potential as a valuable resource for improving soil health and plant productivity.

Research Highlights

·     Vermicomposting can be used to address waste management and recycling

·     The combination of organic waste in the vermicomposting process can enhance quality

·     FT-IR analysis is used to examine the chemical composition of organic fertilizer

·     The vermicompost surface turns more irregular.

·     Vermicompost has a smaller particle size fraction compared to other treatments.
