This research aims to know the effect of vermicompost from the spent coffee ground on the growth of vegetative Capsicum frutescens L. The research was conducted in the experimental field of the Faculty of Mathematics and Natural Science, Universitas Negeri Jakarta, from May until August 2022. This study was conducted using a completely randomized design (RAL) nonfactorial with four treatments and three replications to obtain 12 units of trial. Each experimental unit consisted of 3 seeds, so there are 36 seedlings. The parameters measured were seedling height, number of leaves, stem diameter, leaf area, and the ratio of the canopy and root dry weight. Data analysis used SPSS 24 with ANOVA method on 95% level. The results showed that the dosing vermicompost fertilizer could improve seedling height, some leaves, stem diameter, leaf area, dry weight and ratio of cacao seedling room from spent coffee grouts header. A vermicompost fertilizer dose of 25 g/5 kg produced the highest growth in Capsicum frutescens L. breeding. © Published under licence by IOP Publishing Ltd.
