Abstract

This research used gamma ray irradiation on low doses (micro mutation). The aim of this research was to know the respons of doses level bymicro mutation on gamma ray irridation to the growing and development of Argomulyo variety of Glycine max (L) Merr (M1), the seeds isirradiated by gamma ray by micro mutation was 0 Gy, 50 Gy, 100 Gy, 150 Gy, and 200 Gy. Variation that obtained of each characters atgeneration M1 and M2 influences plants growth and development either through qualitative and quantitative that finally will influence plantsproduction. The average highest genetic variation at M 2 generation of soybean was on 200 Gy doses. Results of the research indicated thatgamma ray irradiation on 200 Gy doses was effective caused of plant variation genetic.

Abstract

The effect of reduced impact timber harvesting technique to structure and species composition of seedling and poles was studied using the data of three plots each sized 100 m x 100 m, which are placed randomly at landing, middle skiddtrail and tips of skiddtrail, respectively. The aim of the study was to know the effect of reduced impact timber harvesting technique to structure and species composition of seedling and poles in tropical forest. The research showed that the forest harvesting caused the changing of the structure and species composition of seedling and poles in natural tropical forest.

Abstract

Currently, the global economy is shaken by the Covid-19 pandemic. Based on the results of the preliminary study at the partner's location, it has economic limitations, including the availability of food supply which has an impact on non-productive communities, including farmers and tenant farmers around Taman Asoka Asri Housing, Tanjung Selamet, Medan Tuntungan, Medan, North Sumatra. All activities that will be carried out by the USU PPM proposing team will of course follow and pay attention to the Covid-19 prevention protocol. The implementation of this community service is carried out in the vicinity of the Taman Asoka Asri Housing, so the activity plan that will be carried out is the use of rice fields for farmers and cultivators in the environment around the Taman Asoka Asri Housing. The area of ​​paddy rice fields managed by smallholders around the Taman Asoka Asri Complex, Tanjung Selamet, Medan Tuntung, Medan an average of 2,725 m2 (0.2725 ha). Rice field management areas that have been successfully managed by partners have become productive areas that can increase income and profits for smallholders.
