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

Sengon (Falcataria moluccana) is a fast-growing species widely planted in Industrial Plantation Forests (IPF/HTI) and has high economic value. The provision of planting material must be well prepared and planned to get the appropriate nursery planting media composition. The Empty Palm Oil Bunches (EFB) biochar application improves soil's chemical and physical properties to provide nutrients for plants. This study aims to determine the effect of the application of EFB biochar on the growth of sengon roots. The experimental design was completely randomized (CRD) by applying four treatment levels and 20 repetitions. The treatments were (A) 100% soil (control), (B) 5% EFB biochar, (C) 10% EFB biochar, and (D) 15% EFB biochar. The data were then analyzed by analysis of variance to see the effect of the treatment on the observed root growth parameters, followed by the 5% Least Significant Difference (LSD) further test to determine differences between treatments. The parameters observed were root length, root volume, root wet weight, and root dry weight. The result showed that the application of EFB biochar increased the growth of sengon roots compared to the control. The greater the dose of the addition of EFB biochar given to the growing media, the more it showed a positive response in improving the growth of sengon roots. In this study, the 15% dose showed the best results compared to other treatments.

Abstract

The customary forest area of Tombak Haminjon (incense forest) located in Pandumaan-Sipituhuta Village has high economic value but has challenges related to overlapping land management. This research aims to determine the history, parties, causes, and conflict resolution in this customary forest. This study used a qualitative approach and purposive sampling of key respondents and in-depth interviews with the stakeholders involved. The results showed that the factors causing the conflict were tenure conflicts. On the one hand, the Pandumaan-Sipituhuta customary forest as incense producer belonged to the indigenous peoples. On the other hand, PT Toba Pulp Lestari (TPL) has also claimed its concession area. The parties interested in using this forest area consist of Key actors, the main stakeholders, and the supporting stakeholders. The determination of customary forest in Pandumaan-Sipituhuta Village has met the requirements to be designated as customary forest after going through a data verification and validation mechanism by a multistakeholder team formed by the Ministry of Environment and Forestry. The determination of the Pandumaan-Sipituhuta customary forest has met the requirements to be designated as a customary forest after going through a verification and data validation mechanism by a multi-stakeholder team formed by the Ministry of Environment and Forestry. Therefore, as a recommendation, it is necessary to accelerate the demarcation of boundaries and the confirmation of the forest area.

Abstract

Sepancong Hill is one of the tourist attractions in Bengkayang Regency. According to the survey, there is an increase in tourist visits from day to day. If it continues, it will lead to environmental problems caused by an excessive number of tourists. This research aimed to get the maximum number of tourists according to the carrying capacity of Sepancong Tourism. The method used in this study is to calculate the Physical Carrying Capacity (PCC), Real Carrying Capacity (RCC), and Effective Carrying Capacity (ECC). The analysis used is descriptive quantitative analysis. Sepancong Hill nature tourism is divided into two areas, such as the campsite and Orchid Park. This research showed that the PCC of both areas is 182 and 356, respectively. The RCC of the campsite and orchid park are 51 and 101. The ECC of the camping area and Orchid Park are 51 and 101. The carrying capacity values for both are obtained by the equation PCC > RCC ≥ ECC. The PCC of the whole hill of Sepancong is 352. It means that the carrying capacity of Sepancong Hill is large and can still accommodate tourists with all tourist activities.

Abstract

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)

Abstract

One of the efforts to increase income is utilizing non-timber forest products in the form of home industries. One of the non-timber forest products utilized by the community and have a business opportunity is the Nipa plant (Nypa fruticans Wurmb). It grows along rivers near estuaries to rivers with brackish water influenced by tides and is included in the mangrove/brackish forest type. The research aimed to analyze the utilization level of nipa (Nypa fruticans Wurmb), examine the income level of the nipa roof craftsman, measure the contribution level of the nipa roofing business to family income, and analyze the relationship between the income level and the utilization of nipa (Nypa fruticans Wurmb). Data was sampled using the census method. The respondents were the craftsmen of nipa roofs (only ten people were still active in making nipa roofs). The required data includes the utilization of nipa resource products, production costs, total revenue, selling price, income from the nipa roofing business, and income from other family members. The results showed that the total production of nipa palm roofs was 303,840/year. The average income of nipa roof craftsmen was Rp10,732,200/year. The income contribution of the nipa roof craftsmen to family income was medium (55%). The utilization of nipa forest resource products had a very strong and positive relationship in increasing the income of nipa roof craftsmen with a correlation value of 0.842.

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
