Abstract

Soybean (Glycine max L.) is a strategic food commodity in Indonesia, but its production declined by 34.06% in 2024 compared with the previous year. This study aimed to determine the growth and production of several soybean varieties in response to gibberellin (GA3) concentrations during the generative phase, as well as the interaction between the two factors. The study was conducted on farmland in Pasar 1 Tanjung Sari, Medan City, North Sumatra, at an altitude of ± 25 m above sea level, from January to March 2023. A Factorial Randomized Block Design with two factors and three replications was used. The first factor was soybean variety (Argomulyo, Grobogan, and Anjasmoro) and the second factor was gibberellin concentration (0, 25, 50, and 75 ppm). The observed parameters were the number of branches per sample, flowering age, and the number of pods per sample. The results showed that variety had a significant effect on the number of branches and the number of pods per sample, but had no significant effect on flowering age. The Grobogan variety produced the highest number of branches (8.22 branches) and pods (173.46 pods). Gibberellin application and the interaction between variety and gibberellin had no significant effect on any of the observed parameters. Keywords : gibberellin, soybean, varieties

Abstract

The use of environmentally friendly fertilizers is increasingly needed to support sustainable agricultural production. Cow urine and landfill leachate contain essential nutrients that can be utilized as raw materials for liquid organic fertilizer. This study aimed to evaluate the effectiveness of liquid organic fertilizer derived from cow urine and leachate on the growth of pakcoy (Brassica rapa L.) and to determine the most effective application concentration. The experiment was conducted in the Greenhouse of Universitas Negeri Medan using a Completely Randomized Design (CRD) with four treatments, namely P0 (control), P1 (10%), P2 (20%), and P3 (30%), each with three replications. Plant height and number of leaves were observed for 21 days. The results showed that the application of liquid organic fertilizer significantly increased plant height compared with the control treatment. The highest plant height was obtained in treatment P2 (20%) with an average of 9.50 cm, followed by P3 (30%) and P1 (10%). In contrast, the treatments did not significantly affect the number of leaves. The findings indicate that nutrients contained in cow urine and leachate were able to support vegetative growth, particularly plant height. Therefore, a concentration of 20% is recommended as the optimum treatment for improving pakcoy growth. Keywords : growth performance, nutrient availability, organic waste utilization, sustainable agriculture, vegetative growth

Abstract

The utilization of organic waste as liquid organic fertilizer (LOF) is an alternative approach to support sustainable agriculture and reduce dependence on inorganic fertilizers. This study aimed to analyze the effect of LOF derived from kepok banana peels, pineapple peels, lamtoro leaves, and eggshells on the growth of green spinach (Amaranthus hybridus L.). The experiment was conducted using an experimental design with four treatments, namely control (without LOF), LOF at concentrations of 15%, 20%, and 25%. The observed parameters included plant height and number of leaves. Data were analyzed using the Shapiro–Wilk normality test, Levene’s homogeneity test, and one-way ANOVA at a 5% significance level. The results showed that LOF application had a significant effect on the number of leaves (p < 0.05), while plant height exhibited an increasing trend but was not statistically significant. The 25% LOF treatment resulted in the highest average growth, with a plant height of 7.17 cm and an average of 6.67 leaves, which was higher than the control. The improvement in plant growth was associated with the availability of macro-nutrients, particularly nitrogen and potassium, which support vegetative tissue development. Therefore, LOF derived from organic waste has the potential to be utilized as an environmentally friendly alternative fertilizer to enhance the growth of green spinach. Keywords: Liquid Organic Fertilizer, Organic Waste, Green Spinach, Plant Growth.

Abstract

Fruit peel waste is one of the organic wastes that has the potential to be used as raw material for liquid organic fertilizer (POC). This study aims to determine the quality of POC based on fruit peel waste enriched with coconut water and rice bran and its effect on the growth of land spinach (Ipomoea reptans Poir.). The study used a Completely Randomized Design (CRD) with four treatments, namely control (P0), POC concentration of 20 mL L⁻¹ (P1), 40 mL L⁻¹ (P2), and 60 mL L⁻¹ (P3), each with five replications. POC is made through fermentation of fruit peel waste, coconut water, rice bran, EM4, and brown sugar for 14 days. Observed parameters included plant height, leaf number, leaf color, plant condition, and macronutrient content of N, P, and K. The analysis showed that the Liquid Organic Fertilizer (POC) contained 0.05% total N, 0.02% P₂O₅, and 0.86% K₂O₅. The application of POC resulted in different growth responses in water spinach plants. The 60 mL L⁻¹ treatment showed the best growth, with a plant height of 19.1 cm and an average leaf count of 7.2 at the end of the observation. The POC application supported the vegetative growth of water spinach plants. Therefore, fruit peel waste has the potential to be used as an environmentally friendly POC raw material and as an alternative organic fertilizer for plant cultivation. Keywords: liquid organic fertilizer, water spinach, fruit peel waste

Abstract

Pakcoy (Brassica rapa L.) is one of the vegetables favored by the community because it has high nutritional content. The fluctuating production of pakcoy crops each year shows that there is a need to develop pakcoy cultivation to meet the needs of the Indonesian people due to population growth and high nutritional requirements. Therefore, improvements in cultivation techniques are needed to increase pakcoy productivity through good cultivation techniques, including the use of a combination of organic and anorganic fertilizers. The aim of this research was to determine and obtain the best combination of NPK fertilizer and kascing fertilizer on the highest growth and yield of pakcoy. This research was conducted in Pangaritan Pagadungan Village, Tempuran Sub-District, Karawang District, from February 2025 to April 2025 using a single factor Randomized Block Design (RBD) experimental method. It consisted of 6 treatments, namely A (1.4 g NPK), B (1.2 g NPK and 20 g kascing), C (1.2 g NPK and 40 g kascing), D (1 g NPK and 60 g kascing), E (1 g NPK and 80 g kascing), and F (0.8 g NPK and 100 g kascing) with 4 replicates. The observation data were analyzed using analysis of variance and further tested using the Duncan Multiple Range Test (DMRT) at the 5% level. The results of this experiment showed there was not significantly effect on plant height, number of leaves, leaf area, and fresh weight of pakcoy plants. The results of the research showed that the average plant height at 21 days after planting (16,32 cm), number of leaves 21 days after planting (6,13 strands), leaf area (395,49 cm2), and daily weight of pakcoy plants (31,88 g). Keywords: Pakcoy, NPK, kascing feztilizer

Abstract

The aren palm (Arenga pinnata) is one of the plantation commodities with high economic value in Indonesia, especially in Marancar District, South Tapanuli Regency. This study aims to find out the types of pollinating insects that visit aren flowers, study the activity of these pollinators, and analyze their relationship with fruit formation in Marancar District, South Tapanuli Regency. The research was conducted for about 4 months using an exploratory survey method through direct observation of blooming aren flowers. Observations were carried out in the morning and evening. The recorded data included the number of insects caught, insect identification, the number of seeds formed, and the weight of the fruit bunches. Insect identification was done at the Laboratory of the Faculty of Agriculture, Graha Nusantara University, Padangsidimpuan, using a morphological taxonomic approach. The research results showed that the number of pollinating insects caught was 2,820 individuals, consisting of 1,685 individuals in the morning and 1,135 individuals in the afternoon. The insects found belonged to the order Coleoptera with 5 families, namely Curculionidae, Staphylinidae, Carabidae, Chrysomelidae, and Hydrophilidae. The Staphylinidae family was the most dominant group with a percentage of 44.15%, followed by Carabidae at 32.98%. The total number of seeds formed in all samples reached 21,746 seeds with a total bunch weight of 1,502 kg. The study showed that pollinating insect activity is higher in the morning and is suspected to influence the success of fruit formation in aren plants.
