Abstract
This study aims to evaluate the effectiveness of an automatic composter based on temperature sensors and microcontroller-driven stirrers, equipped with modified air circulation pipes, in producing high-quality compost using rice washing water as a bioactivator. The method involved a 21-day aerobic composting process utilizing three types of air circulation pipe designs (control, L-shape, and U-shape), with and without the addition of the bioactivator. The materials used included a mixture of market vegetable waste, sawdust, and rice washing water. Parameters observed included temperature, pH, moisture content, organic carbon (C), total nitrogen (N), phosphate (P₂O₅), potassium (K₂O), and C/N ratio. The results showed that the automatic system effectively maintained temperatures in the range of 30–33°C and facilitated a stable decomposition process. The U-shaped circulation pipe design yielded the most optimal results, particularly in temperature control, moisture retention, and achieving a C/N ratio of 12.62 by day 21. The addition of rice washing water as a bioactivator also accelerated decomposition and enhanced the compost's nutrient content. Overall, the integration of the U shaped pipe design with a temperature sensor-based automatic system significantly improved composting effectiveness and efficiency, producing compost that meets the SNI 19-7030-2004 standard.
