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.

Abstract

 Fly ash is used as an ameliorant to neutralize sapric peat soil and as an additional nutrientneeded by plants, but still plants grown in peat media require appropriate fertilization, namely organicfertilizer so that the plants are always met for their nutrient needs. The provision of organic fertilizer canimprove the structure of the soil that is very deficient in organic elements and can strengthen plant roots.This study aims to determine the effect of the growth of rubber seedlings (Hevea brasilliensis Muel. Arg)due to the application of fly ash and chicken manure on peat soil. This study used a factorial CompletelyRandomized Design (CRD), where the first factor was fly ash with 3 treatments and the second factor was  chicken manure with 3 treatments so that 9 treatment combinations were obtained. Observationparameters included soil pH, plant height (cm), number of umbrellas (strands), stem diameter (cm), rootlength (cm). The data obtained were analyzed using Analysis of Variance (ANOVA). If the data obtainedhad a significant effect, then the Duncan Multiple Range Test (DMRT) was carried out at the 5% level.The results showed that the provision of fly ash dose of 100 g/polybag was the best dose that affected thevegetative growth of plants on the parameters of plant height (49.56 cm), stem diameter (4.01 mm) andthe provision of a dose of 150 g/polybag on the parameters of the number of umbrellas (3 strands) androot length (33.09 cm) at 13 WAP. The provision of a dose of 500 g/polybag on chicken manure fertilizerwas the best dose that affected plant growth on the parameters of plant height (53.40 cm), stem diameter(4.36 mm), number of umbrellas (3 strands) and root length (31.03 cm) at 13 WAP. The interaction of flyash treatment 150 g/polybag and chicken manure fertilizer 500 g/polybag had a significant effect on allobservation parameters on peat soil.

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

Cocoa plants (Theobroma cacao L.) are one of the main commodities that are superior in the plantation industry which has an important role for the Indonesian economy. This study aims to determine the effect of the dose of cow manure and biosaccate elicitor on the growth of cocoa seedlings (Theobroma cacao L.). This research method uses a factorial Completely Randomized Design (CRD) with 9 treatment combinations and 3 replications so that 27 experimental units are obtained. The first factor is the dose of cow manure (K), namely: K1: 50 g cow manure / polybag, K2: 100 g cow manure / polybag, K3: 150 g cow manure / polybag. The second factor is the concentration of biosaccate elicitor (A), namely: A1: without biosaccate, A2: 45 mL / L biosaccate elicitor, A3: 60 mL / L biosaccate elicitor. The analysis used was analysis of variance (ANOVA), and continued with Duncan's Multiple Range Test (DMRT) analysis if the effect was significant at the 5% level. The results showed that the treatment of cow manure significantly affected the parameters of seedling height, number of leaves, stem diameter, leaf chlorophyll and dry weight of seedlings. The best dose of cow manure treatment was 150 g/polybag. The treatment of biosaccade elicitor significantly affected the parameters of seedling height, number of leaves and stem diameter. The best concentration of biosaccade treatment was 45 mL/L. The combination of cow manure and biosaccade elicitor showed no significant difference in all observation parameters.

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.
