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.

Abstract

The use of inorganic fertilizers in cocoa nurseries has a negative impact on environmental sustainability, so it is necessary to optimize organic fertilizers that are proven to be environmentally friendly and can be used sustainably. Therefore, an alternative is needed to substitute organic fertilizers, namely the use of Azolla pinnata compost. Azolla pinnata compost has the potential to substitute the use of inorganic fertilizers N, P, and K because the nutrient content is already available in Azolla pinnata compost. This study aims to determine the minimum dose of Azolla pinnata compost that provides the same growth as inorganic fertilizer (NPK) in enhancing the growth of cocoa seedlings in PMK soil. This study used a non-factorial Completely Randomized Design (CRD) consisting of 5 treatment levels with 4 replications. So that 20 experimental units  were obtained. Each treatment consisted of 3 plant samples so that 60 plants were obtained. The treatments consisted of K0: NPK fertilizer 24 g polybag-1, K1: Azolla pinnata compost 100 g polybag-1, K2: Azolla pinnata compost 150 g polybag-1, K3: Azolla pinnata compost 200 g polybag-1, K4: Azolla pinnata compost 250 g polybag-1. The data obtained from the research results were analyzed statistically using Analysis of Variance (ANOVA). If the treatment had a significant effect, it was continued with the Least Significant Difference (LSD) test at the 5% level using the DSAASTAT application. The results of the analysis of variance showed that the treatment of inorganic fertilizer (NPK) and Azolla pinnata compost had a significant effect on the variables of plant height, stem diameter and leaf chlorophyll. The results of the 5% LSD test showed that treatment with a dose of Azolla pinnata compost of 200 g polybag-1could provide the same growth as the administration of inorganic fertilizer (NPK) with a dose of 24 g polybag-1in cocoa seedlings in PMK soil.

Abstract

Cocoa (Theobroma cacao L.) is an important plantation commodity that contributes significantly to Indonesia’s economy as a major export source after the oil and gas sector. This study aimed to determine the effect of kiambang liquid organic fertilizer (LOF) and cow manure compost on the growth of cocoa seedlings in ultisol soil. The experiment was arranged in a completely randomized design (CRD) with two factors. The first factor was LOF: K0 (without LOF), K1 (120 mL LOF + 880 mL water), K2 (150 mL LOF + 850 mL water), and K3 (180 mL LOF + 820 mL water). The second factor was cow manure compost: S0 (without compost), S1 (200 g/polybag), S2 (250 g/polybag), and S3 (300 g/polybag). Each treatment consisted of three replications, resulting in 48 experimental units with a total of 144 seedlings. The results showed that the application of kiambang LOF at 180 mL + 820 mL water significantly increased seedling height, stem diameter, root volume, and dry weight. Cow manure compost at 300 g/polybag significantly improved all growth parameters, including height, stem diameter, number of leaves, root volume, dry weight, and soil pH. The interaction between kiambang LOF (180 mL) and cow manure compost (300 g/polybag) significantly affected seedling height at 3, 5, and 7 weeks after planting (WAP) and root volume

Abstract

Ultisol media are physically relatively infertile and low in organic matter content. This study aims to determine the effect of rice husk biocharand chicken manure compost on the growth of oil palm seedlings in ultisol soil media. The study was conducted from April to June 2025 at the experimental farm on Jalan Gusti Mesir, Medan Jaya Village, Simpang Hilir Subdistrict, Kayong Utara Regency. The experiment used a factorial RAL design consisting of two treatment factors. The first factor was rice husk biochar, which consisted of 3 levels, namely B0 = without biochar, B1 = 75 g/polybag, and B2 = 150 g/polybag. The second factor was chicken manure compost with 3 levels, namely K0 = without compost, K1 = 375 g/polybag, and K2 = 450 g/polybag. The observation parameters included plant height, stem diameter, number of leaves, root length, root volume, and soil pH. The data were analyzed using analysis of variance, and if there was a significant effect, it was followed by Duncan's Multiple Range Test (DMRT) at a 5% level. The results showed that the application of rice husk biocharand chicken manure compost had a significant effect on oil palm seedling growth. The best dose was obtained from the combination of 75 g of biochar and 375 g/polybag of compost, which significantly increased plant height, stem diameter, number of leaves, root length, root volume, and soil pH.
