Abstract

This study identifies and analyzes the occurrence of pest attacks on oil palm plants in the TBM 3 area. Observations were conducted from August 2023 to November 2023 at PTPN IV Sosa, Padang Lawas Regency. The observation began with conducting a survey at the sample collection sites, which are in the oil palm plantation area of PTPN IV Sosa, Padang Lawas Regency. Samples were taken from several areas, namely TBM 1, TBM 2, TBM 3, and TM. The area observed in each section was 1 hectare, with a population of 143 trees in each observation area. The samples used comprised 10% of the total population, resulting in a total of 14 trees observed per area. Observations started from the 10th row at the 5th tree from the roadside, continuing to the 15th tree, and so on, following that pattern. The results indicate that rats, particularly Rattus rattus tiomanicus, are the most significant pests, with an attack percentage reaching 37.16%. In contrast, the incidence of termite attacks is significantly lower, at 2.87%. Although the impact of termite attacks is not as severe as that of rats, continuous monitoring of termite pest attacks remains necessary, especially on younger, more vulnerable plants. These findings highlight the need for effective and sustainable pest control strategies to maintain the health and productivity of oil palm plants.

Abstract

Sorghum is a type of cereal crop that has great potential to be developed in Indonesia because it has good adaptability and is tolerant of drought, so sorghum has enormous potential to be developed as a source of nutrient-rich food. Sorghum contains protein (8-12%) which is higher than rice (6-10%), and its fat content (2-6%) is higher than rice (0.5-1.5%), also contains vitamin B, iron, phosphorus , potassium, and other micronutrients. To improve the quality and quantity of sorghum plants, fertilization is necessary. The current problem is that farmers using excessive chemical fertilization can reduce the quality and fertility of the soil, damage the soil ecosystem, and is not environmentally friendly.Efforts that can be made to improve and restore soil fertility are by organic fertilization. Fertilization is an activity of adding one or more nutrients to the soil when the level of availability is insufficient for the growth and development of a plant. This research aims to evaluate the application of chicken manure on sorghum growth at doses of 0 gr, 100 gr, 200 gr and 300 gr on the growth of stem height, panicle length and sorghum stem diameter. The design used was a non-factorial random design with 4 replications with 24 plants in one plot. The results obtained in this study were not significantly different.
