“…However, in the A2B2 treatment, there was a decrease in the number of worms with the initial number of worms of 400 grams decreasing to 293 grams. This proves that the quality of vermicompost based on potassium content is also determined by the number of earthworms and composting time (Husain et al, 2015). Potassium has an important role in the process of photosynthesis in the formation of protein and cellulose which functions to strengthen plant stems (Ekawandani and Kusuma, 2018).…”

Utilization of coffee skin waste as compost can reduce the use of chemicals in cultivation. The addition of the two materials to compost with various doses of urea and the number of earthworms (Lumbricus rubellus) is expected to help speed up the process of decomposing coffee husk waste into compost and can increase the nutrient content in the compost. Urea and earthworms are used as decomposition materials and enrich the NPK element in the coffee husk waste compost. The result of making organic fertilizer from coffee husk waste compost is in the form of granules. Granulating is done manually to provide innovation in organic fertilizers. The purpose of this study was to determine the best combination of urea and earthworms in improving the NPK nutrient quality of coffee husk waste compost. Research on coffee husk waste compost was carried out at the Green House and Soil Biology Laboratory, Faculty of Agriculture, University of Jember. The method used was a factorial completely randomized design (CRD) with 2 factors, namely earthworms (Lumbricus rubellus) and urea with 3 levels each. The data obtained were analyzed statistically using Analysis of Variance (ANOVA). If there is a data treatment that shows significantly different results, then the Duncan Multiple Range Test (DMRT) is carried out with a significant level of 5%. The interaction between the number of earthworms (Lumbricus rubellus) and the dose of urea in the composting of coffee husk waste has a very significant effect on several variables, namely; Moisture content, Nitrogen, Phosphorus, Potassium, C-Organic, and C/N ratio values, however, did not significantly affect the temperature and PH variables of coffee husk waste compost.

“…This might be associated with the aggressiveness of the earthworm Perionyx excavates in decomposing organic matter from animal waste [27]. The animal waste was consumed by the earthworm so that it underwent decomposition assisted by soil microorganisms in the digestion of the earthworm, then animal waste was removed from the digestive tract in the form of vermicompost [1] [28]. Soil microorganisms in the digestion of earthworms decompose organic matter from animal waste and release CO 2 so that there is a decrease in organic C content.…”

The quality of vermicompost depends on the source of earthworms feed such as animal waste (cows, buffaloes, chickens, and goats). The aim of the study was to obtain high quality vermicompost and to determine the parameters of vermicompost in accordance with the compost quality standard from SNI 19-7030-2004. The experimental design was Completely Randomized Design (CRD) with the treatment of types animal manures: consisted of cow, buffalo, chicken, and goat manures with 6 replications, so there were 24 experimental units. The results showed that the 9 parameters of vermicompost tested complied to the quality criteria of compost from SNI 19-7030-2004. The significant finding of this study was the weight of the remaining earthworms decreased from 12 g at initial weight to 2.42 g for cow dung, 2.38 g for buffalo dung, 1.62 g for chicken manure and 0,63 g for goat dung after harvesting the vermicompost. The highest quality of vermicompost according to the criteria of SNI 19-7030-2004 was cow dung, followed by buffalo dung, goat dung, and chicken manure. According statistical analysis showed that pH (H2O,1:5 w/v) is 8.90 (highest) for chicken manure, 8.60 (medium) for cow dung as well as 8.46 (medium) for goat dung, and 7.90 (low) for buffalo dung. Water content are not significant for all sources of vermicompost which is 50% more. Temperatures of vermicompost from goat dung (28.70°C) and chicken manure (28.29°C) are significant significantly higher than cow dung (27.68°C), and buffalo dung (27.89°C). Organic C content, total N content, and C/N ratio of vermicompost used descriptive analysis. Organic C content was highest in vermicompost derived from buffalo dung, followed by cow dung, chicken manure, and goat dung as well as total N content from goat dung, chicken manure, buffalo dung, and cow dung. Also C/N ratio from low to high are goat dung, chicken manure, cow dung, and buffalo dung.

High population growth in developing countries also increases the amount of waste. Indonesia produces large amount of household solid waste production, namely 2.5 kg per day. Vermicompost is the best alternatives, the cheapest and does not harm the environment. In this study, the vermicompost method was used, worm weight and ratio affected the N, P, and K content in the fertilizer. The results of the sample test, namely the vermicompost time variable, the highest content was obtained at week 7 with N of 0.45%; P of 0.25%; and K by 0.23%. In the variable weight of worms, the highest weight of 300 grams of worms with N of 0.41%; P of 0.34%; and K by 0.23%; and the last variable is the ratio of cow dung and vegetable waste, where the highest content is at a ratio of 1:3 with N of 0.42%; P of 0.27%, and K of 0.22%. The test in this study was taken with 2 samples of the same variable and 1 different variable to determine the effect of these different variables on the N, P, and K content of liquid compost. Then the samples were tested for content using the macro-Kjedahl method to determine the nitrogen content, UV/Vis spectrophotometry to determine the phosphorus content, and AAS to determine the total potassium content.
