Abstract

The productivity of rubber plants in Indonesia is relatively low, so efforts to increase productivity need to be made, one of which is by improving cultivation technology, the limitation of nutrients in the soil of former gold mines is overcome by providing vegetable waste compost. Vegetable waste compost has a C-organic content of 28.89%, N 1.57%, P 1.39%, K 0.69%. This study aims to determine the effect of vegetable waste compost on the growth of rubber seedlings on the soil of former gold mining land. The research was conducted at the Sukaharja Experiment Garden, Gg. Pandan, from April to July 2024. The study used a non-factorial Complete Random Design (RAL) consisting of 5 groups and 5 replicates, there were 25 experimental units, each experiment consisted of 3 samples so that the total number of samples was 75 samples. The parameters observed were the height of the seedlings, the diameter of the stems, the number of umbrellas, and the dry weight of the seedlings. The data is statistically analyzed with Analysis of Variance (ANOVA), if obtained has a real effect, then the Duncan Multi Range Test (DMRT) is continued at the level of 5%. The results of the fingerprint showed that the treatment of vegetable waste composting had a real influence on the variables of seedling height, stem diameter, number of umbrellas, and root volume. The results of the DMRT test at 5% level show that treatment with a dose of vegetable waste compost of 640 g/polybag is able to provide good growth for the growth of rubber seedlings.

Abstract

Coffee is a plantation commodity with significant economic value in Indonesia and globally. Efforts to increase nutrient availability and improve the chemical properties of alluvial soil require the addition of liquid organic fertilizer made from rice straw waste. This study aimed to determine the effect of applying liquid organic fertilizer (POC) made from rice straw waste on the growth of Robusta coffee seedlings in alluvial soil.This study used a non-factorial completely randomized design (CRD) consisting of five treatments. Each treatment had five replications, resulting in 25 experimental units, each consisting of three plant samples, for a total of 75 samples. The treatments were: K0: No POC Application, K1: Concentration 200 mL/L, K2: Concentration 250 mL/L, K3: Concentration 300 mL/L, and K4: Concentration 350 mL/L. The data were analyzed statistically using Analysis of Variance (ANOVA). If a significant effect was found, the Duncan Multiple Range Test (DMRT) was used at the 5% level. Rice straw waste organic fertilizer (POC) at a concentration of 250 mL was the best for increasing leaf number, root length, and plant dry weight. Rice straw waste organic fertilizer at a concentration of 300 mL was the best for increasing plant height and leaf width. Meanwhile, rice straw waste organic fertilizer at a concentration of 350 mL was the best for increasing stem diameter.
