Bioaktivator limbah ikan vs EM4: Solusi hijau untuk pengomposan cepat sampah organik pasar

The primary source of waste generation is household activities, succeeded by traditional markets.  A significant source of waste in Tanjungpinang City District originates from the market.  Initiatives to repurpose market waste, including vegetable refuse, serve as raw materials for organic fertilizer production, employing microorganisms sourced from market waste, specifically fish waste.  The aim was to assess the efficacy of fish waste as a bioactivator in compost production.  This quantitative research employed a semi-quasi-experimental design featuring a control group and a treatment group, focusing on organic waste comprising vegetable scraps and fish waste.  Physical observations revealed a dark hue, a soil-like texture, and an earthy aroma.  The mean temperature of compost without a bioactivator was 28.4°C, with the addition of EM4 it was 28.5°C, and with the incorporation of fish waste as a bioactivator, it remained at 28.4°C.  The average humidity of the compost without bioactivator, with the addition of EM4, is 33.33%, whereas with the addition of fish waste bioactivator, it is 33.7%.  The mean pH of compost without a bioactivator is 6.82 with the addition of EM4 and 6.80 with the incorporation of fish waste as a bioactivator.  The composting duration for vegetable waste without a bioactivator was 16 days, whereas compost with EM4 and fish waste bioactivators required 12 days.  The parameters of temperature, humidity, pH, color, odor, and texture of the compost satisfied the criteria for use as organic fertilizer.  It is advisable to evaluate the parameters of shrinkage, moisture content, carbon-to-nitrogen ratio, location, and environmental factors, as they pertain to plants and community applications.
