Strategy to Strengthening Forest Farming for Sustainable Mangrove Forest Management in the Coastal Area, Deli Serdang, Indonesia

Mangrove forests can be used directly or indirectly by communities/farmer groups around the coast. However, with the rampant forest destruction that occurs, the community or farmer groups need to be equipped with capacity building about the importance of the mangrove ecosystem and its impact on their livelihood. This study aims to identify the condition of mangrove forests in the research area and determine strategies for institutional development of forest farmer groups in coastal areas at the Production Forest Management Unit. The research method used is a qualitative method with interviews; while the analytical method used is the SWOT analysis. Based on the results of the analysis of the Internal Factor Analysis Summary (IFAS) with a strength factor value of 0.054 and a weakness value of 0.47. From the calculation of the internal environment score (IFAS) value, namely the strength factor minus the weakness factor, the value of x was obtained as the horizontal axis 0.054-0.047 = 0.007. Based on the External Factor Analysis Summary (EFAS) analysis results, the opportunity factor had a value of 0.054 with threats having a value of 0.047. The results showed that the external calculation score (EFAS), namely the opportunity factor (opportunities) reduced by the threat factor, obtained the Y value as the vertical. The identification of internal (IFAS) and external (EFAS) factors indicated that the position of institutional development of forest farmer groups in coastal areas was in quadrant one (I) or in an aggressive position that supports the SO development strategy (aggressive development strategy

Analysis of tree quality on the green line using google earth in Tanjung Morawa District, Deli Serdang Regency

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

Analysis of land cover change due to deforestation at Holiday Resort Nature Park, North Sumatra Province, Indonesia

. Deforestation activities in Indonesia are increasingly becoming a real concern. All of these actions resulted in the loss of 50% of the world's tropical forests, impacting the livelihoods of forest-dependent people. Changes in land cover are common in natural resource use areas. Land change is an important issue for planners and policymakers. One of them is the encroachment of the Holiday Resort Nature Park (HRNP) area of North Sumatra Province, which is a form of forest governance and weak law enforcement. Especially in this area, there are Sumatran elephants (Elephas maximus sumatranus), which are classified as critically endangered species. Analysis of land cover change can be used as material for formulating policies. By utilizing the Geographic Information System (GIS), it will be easier to analyze land cover and land use changes. The purpose of this study was to analyze land cover changes due to deforestation at HRNP. Spatial analysis of cover change using imagery and testing the accuracy of deforestation data, land cover satellite imagery, and verification in the field. The results showed that during the past 30 years, there has been deforestation from secondary dryland forest of 2079.3 ha to forest, namely swamp shrubs covering an area of 30.5 ha (1.5%) and non-forest covering an area of 2048.8 ha (98.6%). The highest deforestation rate occurred from 1996 to 2000 as much as 2027.3 ha (97.5%). The form of land cover due to deforestation is plantations 1990.8 ha (95.7%) and land cover forms 57.8 ha (2.8%). The conclusion shows that deforestation was triggered by weak law enforcement from the beginning until now, thus providing a more realistic opportunity for communities to encroac
