Abstract

This study was conducted to look at the types and spatial distribution of non-timber forest products (NTFPs). Data on NTFPs species, distribution, and parts used was obtained through species identification. Meanwhile, NTFP mapping activities use GIS. The results showed that there were 8 types of NTFPs used by the villagers, namely Arenga pinnata, Hevea brasiliensis, Durio zibethinus, Areca catechu, Theobroma cacao, Parkia speciosa, Lansium parasiticum, and Archidendron pauciflorum. They use it for daily consumption and sell it to collectors in the form of fresh fruit, palm sugar, leaves, roots, seeds, and sap. Non-timber forest products are scattered in clusters and unevenly in the village area.

Abstract

. 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 encroach

Abstract

North Sumatra is one of the provinces in Indonesia that has a wealth of natural resources in the form of natural beauty.  One place whose potential natural beauty stands out is the Simarjarunjung area, which is on the north side of Lake Toba. The purpose of this study was to analyze the spatial distribution of tourist objects, natural tourism amenities, and infrastructure in the Simarjarunjung nature tourism area. This research method uses spatial analysis. There are 11 tourist attractions located in the Simarjarunjung natural tourism area that have the potential to be utilized by the manager for natural tourism activities. My Maps technology from Google is used to facilitate access to information so that it is expected to have a positive impact. One of them is the promotion of tourist attractions so that they can be easily accessed by anyone through online networks. The availability of data on the distribution of tourist attractions, attractions and facilities / infrastructure resulting from this research is expected to be a means to be able to increase visitor access to find out information about tourism contained in Simarjarunjung tourist attractions. Each tourist attraction in the Simarjarunjung area has various attractions and tourist facilities, each of which is the attraction and uniqueness of each tourist attraction

Abstract

Tropical forests in Indonesia, which are mega biodiversity countries, have a rich diversity of species, including the Tapanuli orangutan (Pongo tapanuliensis). This species is found in the Batangtoru landscape, mostly in the Other Use Areas (OUA) zone, which can pose a potential threat. The importance of meaningful and long-term local stakeholder engagement. It is necessary to strengthen the management capacity among stakeholders. Therefore, a study of the strategy for developing conservation area management is required. This research aimed to analyze the development and management strategy of conservation areas by related institutions to support the Tapanuli orangutan population and habitat conservation. Despite facing various threats to orangutan conservation, stakeholders still have internal strength. The strategy that must be implemented is to use strength to take advantage of long-term opportunities through a diversification strategy
