Abstract Vermicompost is an organic fertilizer produced from organic waste with the support of earthworms. The type of earthworm commonly used is the earthworm Lumbricus rubellus. Organic waste that can be used to produce vermicompost includes coffee grounds, cow manure, and agricultural waste. In this study, the effects of the amount of medium, the number of worms, and the composting time on the vermicompost production from spent coffee grounds was examined. The vermicompost with different concentrations was also tested to grow Aglaonema flowers. The results showed that the factors affecting the vermicompost production were the amounts of medium, composting time, and the number of worms. The results of the linear regression test showed that the regression coefficient for the amount of medium was 0.34, for composting time was 0.522, and for the number of worms was 0.623. The application of vermicompost as a nutrient-rich organic fertilizer was also successfully tested on Aglaonema brevispathum planting.
