The productivity of cocoa (Theobroma cacao L.) in Indonesia has decreased every year. Organic and sustainable fertilization starting from the nursery can be done as an effort to improve the productivity of cocoa. Organic fertilizers consist of 2, namely solid and liquid organic fertilizers. The use of POC can accelerate the absorption of nutrients by plant roots. POC banana peel kepok contains a number of nutrients needed by plants such as C, N, P, K, Fe, Cu, and Zn. This study aims to determine the effect and dose of differences in the volume of watering POC of good kepok banana peels on the growth of cocoa seedlings. This study used a non-factorial Completely Randomized Design (CRD) with 6 treatment levels and 4 replications. Each treatment consisted of 3 plant samples so that 72 samples of seeds were obtained. Parameters observed included plant height (cm), number of leaves (strands), stem diameter (mm), root length (cm), plant dry weight (g). Cocoa seedling growth data were analyzed using Analysis of Variances (ANOVA). If the results of the analysis have a significant effect, it will be continued with Duncan's Multiple Range Test (DMRT) at a level of 5% and data processing using the SAS application version 9.0. Based on the results of the follow-up test (DMRT), the best watering of POC banana peels on the growth of cocoa seedlings (Theobroma cacao L.) was at the volume of watering POC 120 mL.

Efforts to improve the quality of peat soil to become a more productive medium can be done by providing banana stem compost because it contains macro nutrients that are very much needed by plants. This study aims to determine the role of banana stem compost in peat media to increase the growth of robusta coffee seedlings. This study was conducted at the experimental garden on Jalan Rangga Sentap II, Ketapang Regency, West Kalimantan, from March to June 2024. This study used a non-factorial completely randomized design (CRD) consisting of 6 treatment levels and 4 replications so that there were 24 experimental units, where each replication consisted of 3 plants so that 72 samples were obtained. The treatments were P0: Without banana stem compost, P1: 650 g polybag-1, P2 :700 g polybag-1, P3: 750 g polybag-1, P4: 800 g polybag-1, P5: 850 g polybag-1. Observation parameters included seedling height, stem diameter, number of leaves, root length, and dry weight of seedlings. The data obtained were analyzed statistically by Analysis of Variance (ANOVA). Data showing a significant effect were further analysed using Duncan’s Multiple Range Test (DMRT) at the 5% significance level. The application of banana stem compost to peat-based growing media had a significant effect on the growth of Robusta coffee seedlings. A dose of 850 g polybag-1 of banana stem compost per polybag was found to be the most effective dose for enhancing the growth of Robusta coffee seedlings in peat-based growing media.
