Cocculus orbiculatus is one type of creeping green grass jelly that had many benefits in the health sector and as a food ingredient. The study aims to determine the effect of planting media composition and PSB on the growth of green grass jelly cuttings. This study used a factorial Randomized Complete Group Design (RCGD). The first factor was the composition of planting media, namely soil + biochar (2:1), soil + manure + biochar (1:1:1), soil + manure + biochar (2:2:1), and soil + fertilizer (2:1). The second factor was PSB concentration: without PSB, 10 mL L-1, 15 mL L-1, and 20 mL L-1. Data were analyzed using Analisys of Variance (ANOVA) and Duncan Multiple Range Test (DMRT) further tests at 5% level. The results showed that the use of planting media composition of soil + manure + biochar (2:2:1) with PSB 10 mL L-1 could increase plant height at 6 weeks after planting (146.3 cm) and the number of leaves at 6 weeks after planting. The use of media composition of soil+manure+biochar (2:2:1) can increase plant height, number of leaves, leaf area, fresh weight, dry weight, and chlorophyll content compared to the use of other media compositions. The application of 10 mL L-1 PSB can increase the number of leaves compared to the application of other concentrations.
