Abstract

Abstract: This study analyzes the spatial classification of redistribution priorities for Land Objects of Agrarian Reform (TORA) in Non-productive Convertible Production Forest (HPK Non-Productive) covering 14,310.42 hectares in Sintang Regency, West Kalimantan. The land was verified through the Inventory of Land Tenure, Ownership, Use, and Utilization (IP4T) in 2021 and proposed for forest release in 2022. The results of the study show the persistence of Dayak cultural traditions and reveal three key irregularities: landholdings exceeding the 5 ha TORA ceiling, multiple landholdings by single subjects, and the conversion of land to oil palm. Using a mixed-methods approach combining quantitative, qualitative, and spatial analysis with ArcGIS, the study identified three redistribution priorities: (1) fully eligible parcels (≈1.9%), (2) parcels under 5 ha requiring subject verification (≈26%), and (3) parcels over 5 ha, including forest-use and oil palm areas, requiring stricter screening and conflict resolution (≈71%). The LCDI-based analysis estimates 988,800 tC (3.63 million tCO₂e), with rubber plantations contributing >80%. The study recommends an inclusive TORA scheme that accommodates Dayak customary values by allocating communal forests (hutan ulayat, tana ulen, tana jaka) within each village. This supports forest cover preservation while aligning with the FOLU Net Sink policy, the Low Carbon Development Initiative (LCDI), and the oil palm moratorium, thereby reinforcing sustainable agrarian reform in forest boundary regions. Keywords: Forest Boundary, Incremental Agrarian Arrangement, Low Carbon Development, Non-Productive HPK, TORA Redistribution.

Abstract

The ecotourism is global issues who most talked lately in Indonesia, it is one of the activities special tourist interest which low impacts on natural tourism.The presence of ecotourism in the era of sustainable and tourism development mission should be minimum negative impacts, both on the environment resources and on socio-cultural local values. Ecotourism activities were more oriented on the utilization of natural resources, the natural ecosystems and have not been polluted yet. However, when all of tourism development can not be separated from the negative impacts, such as ecosystem distress in ecotourism object when visited by large number of tourists, there are many conflicts of interest between the ecotourism management with local communities, especially regarding the benefits sharing and its accessibilities. The purpose of this paper is to identify the environmental impacts arising as a result of ecotourism activities and to find out alternative efforts in mitigating the environmental impact of ecotourism activities. Carrying capacity of ecotourism is not just limited to the number of visits, but also covers other aspects, such as: (1 ) ecological capacity that is ability of natural environment in providing the needs of tourists, (2) physical capacity, that is ability of facilities and infrastructure in providing the needs of tourists,  (3) social capacity, that is ability to absorb tourism activities without the negative impacts on the local communities, (4) the economic capacity, that is ability to absorb destination commercial efforts and accommodateany interests of the local economy. Keywords: Ecotourism, environmental impacts, carrying capacity.

Abstract

Tourist arrival and its effects on the sustainability of biodiversity in Sulawesi is one of the interesting public issues discussed at this time. Object of the most visited by tourists are protected forest ecotourism. In a protected forest tour are endemic plant and animal species that must be protected and preserved in order to sustain their ecosystem. Forest ecosystem suggests the dynamic interactions between plants, animals, and microorganisms and their abiotic environment working together as a functional unit. Ecosystems will not sustain if they are imbalance. However, thare are many human activities, especially tourist activities lead to major implications on biodiversity of natural vegetation in Sulawesi. This paper presents informations and data on vegetation biodiversity and information about tourist activities in maintaining vegetation biodiversity. There are 57 endemic plant species in Sulawesi are still maintained and preserved. Most are in Gorontalo about 16 species, in North Sulawesi about 13 species, in Southeast Sulawesi 10 species, in Central Sulawesi 9 species and in South Sulawesi, 9 species. Activities carried tourists in maintaining diversity of species include: planting trees, learning and research the endemic species of plants and animals, and collect solid wastes in the tourism areas. These activities suggest a positive impact on the sustainability of forest ecosystems and economic benefits for the local communities. Keyword : Tourist activities, biodiversity, endemic species.

Abstract

This study aims to analyze the tourists' perception about the importance and satisfaction on the product of fisheries tourism, and to assess the visiting time of tourist based on climate conditions. The research was conducted in May to June 2013 in Ngebel Lake, Ponorogo. We used descriptive quantitative approach, with 45 respondents. Data collected from interview, questionnaire and observation. Analytical methods were used to determine the perception of tourists on the satisfaction and interest in fisheries tourism products, i.e. Importance Performance Analysis (IPA). We also used Tourism Climate Index (TCI) to determine the visiting time of tourist. The results show the value of satisfaction and tourist interest is low, therefore the improvement of several aspects become important. It is encompasses: a) the existence of parking area; b) the condition of Ngebel Lake; c) planning and management system, the condition of the local community; and d) activities of fish course restaurant and fish farming system of floating net cages. TCI value indicates ideal conditions for tourists traveled in Ngebel Lake is in November (convenience index value of 106), in December (97) and in April (94). This appropriate time to visit Ngebel Lake is expected to create a good impression for the tourists and enjoy the various fisheries activities in Ngebel Lake.
