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.

Abstract

Deforestation results in environmental degradation, so it is necessary to conduct a study to determine land use changes that occur and predict land changes with appropriate directions to support the Protected FMU Unit II FMU Region XV Kabanjahe management plan. This study aims to analyze changes and predictions of land use in 2013-2033, factors that influence land use change, and formulate directions for land use plans in Protected FMU Unit II FMU Region XV Kabanjahe. This research uses a Geographic Information System approach with the Artificial Neural Network (ANN) method prediction model. Factors driving land use change as model inputs consist of distance to road, distance to permit, distance to settlement, distance to river, elevation, geology, soil type, and slope. The results showed that there has been a decrease in dryland forest by 6,957 ha in the 2013-2018 period, and the driving factor that has the highest degree of relationship based on the results of the correlation test is the distance to the road, which is 0.2444. The land use change prediction model has an accuracy of 89.42% based on Kappa Index Agreement (KIA). The direction of the land use plan in Protected FMU Unit II FMU Region XV Kabanjahe in 2033 consists of Protected Forest Area which has the largest area, namely 64,678 ha, Production Forest covering 7,077 ha, and Limited Production Forest covering 9,278 ha.

Abstract

This study evaluates the distribution and condition of vegetation within the green belts of Medan City Center in 2025 by employing the Normalized Difference Vegetation Index (NDVI) derived from Sentinel-2 satellite imagery, supplemented by field verification through purposive sampling. The analysis reveals that the findings indicate that non-vegetated category (NDVI < 0.1) dominated, encompassing 12,240.98 hectares or approximately 43.98%, whereas the dense vegetation class (NDVI 0.3–0.4) represents the smallest portion, covering only 3,009.70 hectares (10.81%) of the total area.Vegetation index values within these urban corridors range from a maximum of 0.55 to a minimum of -0.04, where lower values are predominantly associated with built-up areas and open land, while higher values are restricted to riparian buffers and fragmented green spaces. Spatial pattern analysis, utilizing a 500-meter buffer, highlights significant disparities in vegetation distribution and underscores the mounting pressure of urbanization, which has compromised the ecological functions of the city’s green infrastructure. Consequently, these findings emphasize the critical need for strategic planning and robust policy interventions to revitalize green open spaces as essential ecological infrastructure; therefore, the primary recommendation focuses on expanding green belt vegetation through intensification and protection efforts to ensure that ecological, social, and aesthetic functions are maintained sustainably within the Medan City Center.
