Abstract

The physical properties of the soil that need to be considered are the problems of degradation and soil structure due to management functions. In addition, on cultivated land that is not eroded, organic material is lost quickly.This research was carried out through 2 stages of activities, namely field activities and analysis activities. Stages of field activities were carried out at the Kebun Sinar Pandawa Palm Oil Plantation PT. Sinar Pandawa, Labuhanabtu, North Sumatra Province with a height of 28 meters. The method used in this research is a free grid measurement method at a semi-detailed survey level (observation frequency of 1 sample per 500 meters). Carrying out soil sampling at up to 5 sampling points with a distance of 100 meters in the field using a random method, spread over a predetermined area based on the base map. Land Use Research Results withSoil texture at PT. Sinar Pandawa, Labuhanbatu Regency, Sandy Clay, The Bulk Density value shows low, soil porosity is still high, the soil color looks relatively dark, and the soil water content is still relatively normal.

Abstract

Rice (Oryza sativa L.) is a strategic food commodity and a primary source of carbohydrates for most of the world's population, including Indonesia. One effort to increase rice production is through mutation.The purpose of this study is to study the influencegamma ray irradiation on several rice varieties at the germination seedling phase. Gamma ray irradiation was carried out in January 2025 at the Center for Isotope and Radiation Applications (PAIR), National Nuclear Energy Agency (BATAN), Pasar Jumat, Jakarta, while planting was carried out on Jl. Belibis, Rantau Selatan District, Labuhanbatu Regency in March 2025. The study used a non-factorial Completely Randomized Design (CRD) namely gamma ray irradiation at the following doses: 0 Gy (control/no radiation dose); 50 Gy; 100 Gy; 150 Gy; 200 Gy; 250 Gy; 300 Gy; 350 Gy; 400 Gy and 450 Gy.Observations were made on germination rate, seedling height, and root length. The data were analyzed using analysis of variance followed by Duncan's multiple range test (DMRT). The results showed a visible effect of gamma ray irradiation on germination rate. Gamma ray irradiation also affected average seedling height and root length.The lowest reduction in germination and seedling height occurred in the Sibenang rice variety at a dose of 450 Gy, at 0%. Meanwhile, the shortest root length was in the Ciherang rice variety at a dose of 450 Gy, at 1.93 cm.

Abstract

Pakcoy (Brassica rapa L.) is a type of mustard that is quite economical. Currently, the pakcoy plant is used by the community in various dishes. This plant is quite easy to cultivate and only requires a short time of about 3-4 weeks. The aim is to obtain data on the growth response and production of pakcoy plants to the application of liquid organic fertilizer banana peels. Liquid fertilizer is a fertilizer whose basic ingredients are animals and plants that have been undergoes fermentation and the product form is in the form of liquid, one of which is banana peel waste which is used for the manufacture of liquid fertilizer because it contains micro elements N, P and K. Because many people process processed production from bananas which always produce banana peel waste in processing the waste is only disposed of and left to pile up by the community, if not handled quickly it will produce an unpleasant odor so that it will pollute the environment, one alternative is the service team invites socialization and training to the community by processing the banana peel waste into liquid organic fertilizer with the fermentation process tation, so that people can use liquid organic fertilizers instead of using chemical fertilizers that are more expensive for all plantation crops.
