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

Rice is a staple food and a primary ingredient for many communities. The available rice supply is expected to meet the growing demand. This study aims to investigate the effects of gamma-ray radiation on the growth of rice plants of the Silumat variety and to determine the optimal gamma-ray radiation dose for their growth. The research employs an experimental method using a non-factorial Randomized Block Design (RBD) with 10 treatment levels: R0 = Control (No Radiation), and radiation doses of 50, 100, 150, 200, 250, 300, 350, 400, and 450 Grey. The results showed that gamma radiation significantly affected the viability, plant height, and number of tillers in the local rice variety Silumat (Oryza sativa L.). Low doses, particularly 50 Gy and 100 Gy, exhibited a stimulating effect (hormesis), enhancing germination, plant height, and tillering. In contrast, higher doses (>150 Gy) tended to reduce all parameters due to physiological and genetic damage. This study provides specific information on the optimal gamma radiation dose range to stimulate the growth of the Silumat variety, which can serve as a reference for plant breeding programs based on induction treatment.

Abstract

Oil palm (Elaeis guineensis Jacq.) is a plantation crop that plays a vital role in the Indonesian economy. This study aims to analyze production costs, income, and the effect of production costs on oil palm farming income in Lobusona Village, Labuhanbatu Regency. The research sample consisted of 30 farmers selected through simple random sampling. Data were analyzed using multiple linear regression. The results show that the average production cost incurred by farmers was IDR 60,600,167 per year, while the average revenue reached IDR 136,266,783 per year. This yield resulted in a net income of IDR 75,666,617 per year, or approximately IDR 24,532,139 per hectare per year. The F-test results indicate that production costs, when considered simultaneously, have a significant effect on income (Sig. 0.000 < 0.05). Meanwhile, the t-test results reveal that fertilizer costs had no significant effect, whereas pesticide and labor costs had a significant adverse effect on income. Conversely, annual production, plant age, and the price of fresh fruit bunches (FFB) had a significant positive effect. The coefficient of determination (R²) of 0.996 demonstrates that 99.6% of the variation in income is explained by the variables included in the model. These findings suggest that the efficient allocation of production costs—particularly for pesticides and labor—is crucial for improving the profitability of oil palm farming.

Abstract

Oil palm (Elaeis guineensis Jacq.) is one of Indonesia's leading plantation commodities and plays a strategic role in the national economy. The purpose of this study was to determine the effectiveness of EFB compost as an alternative source of potassium, analyze its effect on potassium nutrient uptake, and assess its impact on oil palm yields at PT Evans Group. This research method used a field experiment approach by comparing two treatments: a control treatment without EFB compost and a treatment with EFB compost at a dose of 50 kg per plant. The results showed that compost application had a positive effect on plants, as indicated by increased leaf potassium content in the compost treatment compared to the treatment without compost. Although the difference was not significant, these results indicate that compost plays a role in increasing potassium availability and uptake by plants, thus supporting better plant growth.

Abstract

Oil palm (Elaeis guineensis Jacq.) is a tropical plantation crop with high economic value and is one of Indonesia's mainstay commodities. The purpose of this study was to determine the level of basal stem rot (Ganoderma boninense) infestation in oil palm plants at the Pangkatan Plantation of PT. Evans Group, the magnitude of the resulting fresh fruit bunch (FFB) yield losses, and the relationship between disease severity and the decrease in FFB yield. The research method used was a survey method with a quantitative descriptive approach. The results showed that the level of ganoderma infestation in Block A1 was relatively low at 8.7%, but had a significant impact on oil palm productivity. Trees attacked by ganoderma produced lower fresh fruit bunch (FFB) weights than healthy trees, thus indicating that plant health significantly affects production results.

Abstract

This study aims to analyze the intensity of rhinoceros beetle (Oryctes rhinoceros) attacks on oil palm leaf sheaths during the Mature Plant (TM) phase at PT. Binanga Karya. The rhinoceros beetle is a major pest of oil palm plants, reducing vegetative growth and potentially impacting crop productivity if not properly controlled. This study was conducted through a field survey using purposive sampling in mature plant blocks. Observed parameters included the number of infested plants, the number of leaf sheath holes, and the level of leaf sheath damage as an indicator of pest attack intensity. The data obtained were analyzed descriptively and quantitatively by calculating the percentage of attack intensity based on the ratio between the number of infested plants and the total sampled plant population. The results showed that rhinoceros beetle attack intensity was mild to moderate, with variations in the level of damage between plant blocks. The leaf sheath damage found generally consisted of bore holes and bite marks at the base of the sheath. Although the attack has not yet caused a significant decrease in production, the presence of this pest still requires vigilance because it has the potential to increase the level of damage if the population is not controlled. Therefore, appropriate and sustainable pest control efforts are needed to maintain plant health and the stability of palm oil production.
