This research investigates different watering patterns in non- reversible compost production processes to compare their effectiveness in facilitating compost decomposition. The controlled factors include composting duration, watering duration, composting materials, compost pile size, and water quantity. Four watering patterns were conducted: 1) manual watering, 2) drip irrigation in a fishbone pattern, 3) drip irrigation in a straight-line pattern, and 4) drip irrigation in a zigzag pattern. Piles were watered every 7 days, and data on temperature and moisture content in the compost piles were collected every 5 days throughout the 61-day experiment. Upon completion of the composting process, organic matter content and pH levels were analyzed. The results indicated that drip irrigation in a zigzag pattern, applying 40 liters of water per week, was the most efficient method. This pattern resulted in an organic matter content of 47.1% and a pH level of 8.16. The compost produced through this method exhibited characteristics of being loose, crumbly, and dark brown in color, suitable for soil improvement purposes.
