Abstract

There are some environmental problems in the development of urban areas including air, water and soil pollution. The high growth level of population which are followed by the establishment of industrial zones and settlements areas have cause less of vegetation areas. The purpose of this study was to identify areas which is potential to be developed as afforestation areas using geographic information systems by applications using SPOT 5 satellite imagey. Afforestation planning of bare land is in the form of afforestation in settlements areaswith total area of ​​7.14 hectares. Afforestation planning in the green belt is afforestation along roads and the river. There is 169.52 kilometers of road length to be afforested. Suitable plant species could be Pterocarpus indicus, Filicium decipiens, Polyalthia longifolia, Mimusops elengi, Switenia mahagoni, Casuarina equisetifolia, and Oreodoxa regia. Along the river bank of 17.27 kilometers length is recommended to be afforested with bamboo plants. Keywords: Reboisation Planning, SPOT 5 imagery, Geographic Information Systems (GIS)

Abstract

The mycorrhizal is affected by biotic and abiotic factor. The purpose of this research is to explore the mycorrhizal on the soil of former gold mine community in Mandailing Natal so that we know the types of native mycorrhizal of the area. The data got from this research used to helps land reclamation efforts by the application of mycorrhizal on land mine. This activity will improve the condition of the damaged environment or increase productivity of the land. This research use soil separating method to obtain spores and root coloring method to find out root colonization. Result from this research is 2 genus spores are found they are genus Acaulospora 5 types of spores / 10 g soil and genus Glomus 11 types of spores / 10 g soil. The percentage of mycorrhizal colonization on former gold mine community in  Mandailing Natal is revolve between 8,12% - 28,55% .Key words: Mycorrhizal, genus Acaulospora and genus Glomus, former gold mine land community

Abstract

The community service program for the mandatory lecturer scheme in 2021, Universitas Sumatera Utara, is foc Integrasi Agroforestri dan Sistem Budidaya Lebah Madu (Trigona Sp.) dalam Penguatan Food Estate di Humbang Hasundutan.  used at the food estate location, Humbang Hasundutan Regency. The purpose of this community service program is to develop a group of forest communities around the location of the food estate that are economically independent through the skills of honey bee cultivation of Trigona sp. in strengthening food at food estate locations. This program integrates forestry, agricultural, and honey bees Trigona sp. to form an interrelated cultivation system for the sustainability of ecological, economic, and social aspects. This program is carried out in the form of assistance in providing honey bee sires Trigona sp. and training in honey bee cultivation management. This program is expected to be able to have a positive impact on the community of food estate farmer groups as a companion business in managing food estates based on agricultural commodities.

Abstract

The Universitas Sumatera Utara has various types of trees scattered in the surrounding environment. Swietenia macrophylla, Mimusops elengi and Polyalthia longifolia are the three most common tree species found on campus. To maximize the potential for utilizing tree species on the Universitas Sumatera Utara campus, several efforts can be made, one of which is by exploring the presence of cellulolytic fungi. Cellulolytic fungi are fungi that are able to hydrolyze cellulose which can produce cellulase enzymes. This study aims to obtain the potential and identify cellulolytic fungi from the soil under Swietenia macrophylla, Mimusops elengi and Polyalthia longifolia stands. Sampling was taken by making 3 plots on each type of stand measuring 20 m x 20 m with a soil depth of 0 – 20 cm. In each plot, 5 sampling points were made. The soil taken from each type is then composed. Isolation of cellulolytic fungi was carried out using Carboxy Methyl Cellulose (CMC) media. The potenstial of cellulolytic fungi is obtain by calculating the cellulolytic index. All isolates obtained were identified morphologically down to the genus level. The result showed that the potency of the cellulolytic fungi ranged from 0.05 to 1.36. The identification results that the isolates included the genus Aspergillus and Trichoderma.

Abstract

The arboretum of the Universitas Sumatera Utara (USU) is an area for collecting and conserving tree species in North Sumatra. One of dominant family found in USU Arboretum is Moraceae.  The objective of this reserach was to determine Moraceae diversity in the USU Arboretum. The census approach of vegetation analysis was used to determine the identity and abundance of Moracea. The research found 9 (nine) Moraceae species belongs to two genera in the USU arboretum, those were Ficus microcarpa, Ficus elastic, Artocarpus heterophyllus, Ficus padana, Ficus fistulosa, Artocarpus altilis, Ficus benjamina, Ficus ampelas and Ficus hispida. The species with the highest density value (57.92%) is Ficus hispida. The diversity index, richness index, and species dominance index were all quite low in the research location, with values of 1.455, 1.226, and 0.370, respectively. Meanwhile, the species evenness index at the research location is 0.662, which is classified into moderate. To improve the diversity of Moraceae in the USU arboretum, species enrichment activities are needed.
