Abstract

South Labuhanbatu is a district in North Sumatra which is synonymous with a very large area of oil palm plantations. The area of oil palm plantations in South Labuhanbatu district is around 57,307 hectares with a total production of 640,196.60 tons. This study aims to determine the levels of nutrients uptake of nitrogen (N) in oil palm plants produce. So far, the status of testing for potassium nutrient uptake in people's plantations in Perlabian Village, Kampung Rakyat South Labuhanbatu District, has never been carried out. Fertilization and care are carried out through knowledge from generation to generation, so it is important to study the status of nitrogen uptake in oil palm leaves. This research was carried out using a semi-detailed free-level grid survey method with a density of 100 meters. A total of 6 leaf samples were taken on the 17th leaf midrib and then 70% alcohol was applied and put into a plastic sample for further testing in the laboratory of PT. Socfindo. The results showed that the 2nd leaf sample was deficient and 1, 3, 4, 5 and 6 leaf samples were at the optimum point. The uptake of N (nitrogen) in the leaves of oil palm plants in smallholder plantations in Perlabian Village, Kampung Rakyat District, showed that the total N content of leaves was included in the optimal category.Keywords: Nitrogen, Nutrient Uptake, Oil Palm Plants have

Abstract

This study aims to identify pest insect species and the level of damage they cause to oil palm plants in Air Merah Village, Kampung Rakyat District, South Labuhanbatu Regency. The research method used is a descriptive quantitative approach with purposive sampling techniques. The results showed that six species of pest insects were found, classified into three orders: Lepidoptera, Coleoptera, and Orthoptera. The most commonly found species was Setothosea asigna. The level of plant damage varied, with an average percentage of 27.46%, categorized as moderate damage. Pest insects attacking oil palm plants have the potential to reduce plant productivity, making it necessary to implement proper pest control strategies to minimize their impact. This research provides essential information for farmers in mitigating pest attacks and improving oil palm production.

This study aims to determine the analysis of the palm oil processing identification process at PT. Asam Jawa in South Labuhanbatu Regency. The determination of the research location was done intentionally (purposive). The subjects of the study were the parties involved in the study, namely PT. Asam Jawa and the object of the study was the production of crude palm oil. Data collection was carried out using historical data methods and literature studies. The results of the study showed that the palm oil processing process starts from (a) fruit harvesting; (b) transportation of FFB; (c) receipt and sorting of FFB; (d) boiling station (Sterilizer); (e) threshing station; (f) pressing station; and (g) purification station (Clarification Station)

Abstract

Chili pepper (Capsicum frutescens) is one of the important horticultural commodities in Indonesia, widely cultivated due to its spicy flavor and high economic value. This study aims to compare the effectiveness of various planting media and fertilizers in promoting the environmentally friendly growth of chili pepper plants. The study employed a Factorial Randomized Block Design (RAK) with treatments including: Control (without cow manure), 2 kg of cocopeat and 1 ounce of cow manure, 2 kg of cocopeat and 1.5 ounces of cow manure, 2 kg of cocopeat and 2 ounces of cow manure, 2 kg of soil and 1 ounce of cow manure, 2 kg of soil and 1.5 ounces of cow manure, and 2 kg of soil and 2 ounces of cow manure. Data analysis was conducted using ANOVA and BNT post-hoc tests. The results showed that the planting media did not significantly affect plant height or the number of leaves, though variations in values were observed across treatments. In cocopeat media, the treatment of 2 kg of cocopeat and 1.5 ounces of cow manure resulted in the highest plant height at week 4, measuring 30.03 cm, followed by 2 kg of cocopeat and 1 ounce of cow manure (29.23 cm), 2 kg of cocopeat and 2 ounces of cow manure (29.20 cm), and the control treatment (28.46 cm). The highest number of leaves was also found in the 2 kg of cocopeat and 1.5 ounces of cow manure treatment, with 16.66 leaves, although in the second week, the control treatment recorded only 6.33 leaves. In soil media, the 2 kg of soil and 2 ounces of cow manure treatment produced 17.66 leaves, with variations in the second week noted between the cow manure treatments and the control group.

Abstract

Honey water guava (Syzygium aqueum) is one of the newest high-quality commodities and is increasingly being cultivated by farmers in various regions. This study aimed to evaluate the effects of applying organic plant growth regulators (PGRs) derived from sprout extracts at different doses on the growth of water apple (Syzygium aqueum) plants. A completely randomized design (CRD) with a single treatment factor was employed. The results demonstrated that the 60 mL treatment of ZPT Organic Benefits Extract was the most effective in promoting plant growth, achieving an average height of 10.8 cm and five shoots at 4 weeks after planting (WAP), compared to the control treatment, which reached only 8 cm in height and two shoots. These findings indicate that the 60 mL dose of organic PGR extract from sprouts significantly enhanced growth and stimulated shoot development relative to the other treatments.

Abstract

Sustainable agriculture requires the prudent management of natural resources, including the judicious use of fertilizers and other inputs. One of the primary challenges faced by farmers is the decline in soil fertility resulting from the prolonged use of chemical fertilizers. This study aims to evaluate the effect of Kasgot fertilizer on soil chemical properties, specifically soil pH, organic carbon content, total nitrogen (N), available phosphorus (P), and available potassium (K), in cucumber cultivation. Soil sampling was conducted using a proportional sampling method, where sample points were selected based on soil availability and were representative of the cucumber cultivation area. The results indicated that, based on the analysis of phosphorus (P) and potassium (K) nutrient content, the treatment with 5 grams per planting hole was most effective in increasing phosphorus availability to 0.2907%, classified as high. Meanwhile, the treatments with 10 grams and 20 grams per planting hole were more effective in increasing soil potassium content to 0.0724% and 0.0708%, respectively, both of which were classified as moderate to high.

Abstract

This study aimed to determine the effect of fertilizer application with a concentration of 5 grams per liter on the vegetative growth of immature oil palm plants (TBM). The study was conducted for 4 weeks with observation intervals once a week, using two treatments: control and application of 5 grams per liter fertilizer, each with 10 replications. Observed parameters included plant height, number of leaves, stem diameter, and leaf length. Data were analyzed using ANOVA test and continued with DMRT test at the 5% level. The results showed that the application of 5 grams per liter fertilizer had a significantly different effect on all growth parameters compared to the control in each observation week. This treatment consistently resulted in higher growth, so it can be concluded that the application of 5 grams per liter fertilizer is effective in increasing the vegetative growth of immature oil palm plants.
