Abstract

This research describes coastline and land cover changes of Lhoknga beach after tsunami. This research used images satellite of Landsat 5 and Landsat 8. Image interpretation used supervised classification approach with the method of Maximum likelihood classifier. Image interpretation used visual analysis based on monogram North Sumatra. The research showed that coastline changes are caused by abrasion and accretion. Abrasion reduced the area of the beach 45,81 hectares in the period 2000 to 2013. Accretion increased the area of the beach 36,99 ha in the period 2000 to 2013. The largest land cover change between 2000 and 2005 were open land and bush.  The open land increased 716.95 ha and bush reduced 1.658,98 ha. The largest land cover changes in the period 2005 to 2013 were bush and forest. The bush increased 1.078,22 ha and forest reduced 823,01 ha. Key words: coastline change, land coverage, Aceh tsunami, Lhoknga Beach.

Conditions Nature Reserve is still intact and is a source of water for the surrounding area. The purpose of this study was to determine the changes in land cover and determine the condition land cover there in 2006 and 2013 by using the interpretation of Landsat ETM 7 and 8. Landsat TM image analysis and classification change detection method using Arcview Gis 3.3 and ERDAS IMAGINE 8.5. Image analysis were performed, land cover in the Nature Dolok Sibual-Buali classified into 5 classes of land cover namely primary dry forest, secondary dry forest, scrub, vacant land, water bodies and not identified (clouds and cloud shadows). The results obtained by the classification of the primary dry forest is 68.5 ha changed into a secondary dry forest and 11.8 ha to Body Air.Pada secondary dry forest area of ​​583.28 changes ha become better forest and 30.61 ha turned into Shrublands., 74 ha.Sedangkan on bushes changed into the body area of ​​3.42 ha of water. Keyword : Land coverage change, Dolok Sibualbuali Nature Reserve.

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

Tapanuli Orangutan (Pongo tapanuliensis) is a globally critical species (critically endangered) due to the decreasing area of natural habitat. Orangutans can reach out of their natural habitat outside the forest and into community fields for feeding. Orangutans make the other land use not only a place to stopover but also a home range and living area marked by nests. The study aims to obtain information on the characteristics of nests and the estimated population of the Tapanuli orangutan (TO) in the other land-use area. This research method uses line transects placed by systematic sampling with a distance between lines of 3 km and population data analysis using calculations from the van Schaik formula. From the results of the 11 research lines, 14 nests were obtained consisting of 3 class B nests, 5 class C nests, 3 class D nests, and 3 class E nests. The characteristics of the most dominant nests were class C with the most preferred positions II and III and nest finding highest in Quercus maingayi tree. The research found that the density of the TO was eight individuals/1000 ha.

Abstract

City development with unfriendly development causes the quality and quantity of open green space to decrease. Google Earth is an interactive mapping application released by google, which displays a digital visualization of the geographical shape of the earth. This study aims to determine the type and quality of trees on the urban forest in the Tanjung-Morawa sub-district and to map the quality of trees on the urban forest in the Tanjung-Morawa sub-district. This study uses a modified method of tree quality assessment with two criteria: tree health and technically criteria. From the observation result, there are 18 trees, Glodokan (Polyalthia longifolia) with the highest number, as many as 842 trees, and Dadap Merah (Erythrina crista goly) as the tree with the least amount. The quality of the trees in the urban forest shows a moderate good quality, where the highest health is in the medium category and for the technical in the low category. Trees that are recommended to be cut have a cumulative ≥ 2,5 Angsana trees with a total of 129 trees, and the highest cumulative percentage is the Banyan tree at 66,67%. The Mango tree has the lowest rate at 8,70%. Google Earth can’t be used optimally because of the low-resolution image quality. Image capture data in google earth has not been updated; the unstable internet connection and the time of the retrieval and processing of field data are not the same as the time retrieval and processing.

Abstract

Mangroves are a unique ecology that resides in places with salinity, which are inundated at low tide when there is no flooding and at high tide. Mangrove forests that are increasingly damaged cause the quality and quantity to decrease. Using different species of fungi that can accelerate the growth of mangroves is one attempt to increase and get high-quality mangrove seeds. This study aims to shed light on the fungi that can dramatically improve the growth of Avicennia marina seedlings. Mangroves can absorb organic and non-organic materials produced by decomposing microorganisms, which come from leaf litter or other decomposed materials. In this experiment, several fungal species were used, including Aspergillus niger, Aspergillus sp. 2, and Aspergillus sp. 1. The findings demonstrated that the fungus might speed up A. marina seedling growth. The plant's height, diameter, leaf width, and total dry weight were all altered as a result. Based on the study's findings, it can be said that Aspergillus niger provided the best growth for A. marina seedlings

Abstract

The forest area in Batu Bara Regency is managed by Unit X KPHL Batu Bara, which has a coastal area with coastal forest characteristics and is dominated by mangrove ecosystems. Currently, the condition of land cover in the forest area in Batu Bara Regency has undergone many changes in terms of function and designation, so an analysis is needed to determine the condition of the mangrove ecosystem. Spatial analysis was carried out to ensure the area with mangrove vegetation land cover in the Unit X Batu Bara management area, which will then be the basis for determining the location of the mangrove vegetation analysis. Based on the results of spatial analysis of changes in land cover, land cover in Unit X KPHL Batu Bara is dominated by dry land agriculture and ponds. Meanwhile, land covered with secondary mangrove forest criteria has increased in area from previously ± 297.79 Ha (8.11%) to ± 535.89 Ha (14.59%). Based on vegetation analysis, the results of the study indicate that the condition of the mangrove ecosystem in KPH Unit X KPHL Batu Bara is currently in a condition of sparse density for tree classification, moderate density for sapling classification, and dense for seedling classification with moderate species diversity.
