Abstract

Suku Anak Dalam (SAD) is a traditional tribe in Jambi Province. They live in the forest and utilize forest products including non-timber forest products (NTFPs) to meet their daily needs. One of the SAD population areas is in the Bukit Duabelas National Park (TNBD). The purpose of this study was to determine the type and economic value of NTFPs that SAD utilized to meet its economic needs in TNBD. The study was conducted in January-May 2019 in the buffer village of TNBD with the method of field observation, interviews and literature review. Respondents were determined by simple random technique while the number of respondents was determined by Slovin Technique. Data were analyzed descriptively after complete tabulation. The results showed that there were 10 types of NTFPs that were utilized economically by SAD. The highest economic value of NTFPs is Rattan with a total value of Rp. 554,887, 000 / year or with a proportion reaching 53.25% while the lowest economic value of NTFPs is Balam sap with an economic value of Rp. 1,800,000 / year with a proportion of 0.17%. From these results it can be concluded that NTFPs have enormous benefits to the SAD economy and livelihood in TNBD.

Abstract

Amorphophallus titanum is native to Sumatra's rainforest that was first recognized in the world of science after it was discovered by Dr. Odoardo Beccari in 1878 in the Lembah Anai, West Sumatra. Amorphophallus titanum is protected by the Government Regulation Number 7 in 1999 and being categorized as Vulnerable to Red List Data Book issued by IUCN (International Union for Conservation of Nature and Natural Resources) in 1997. This study aims to examine the natural population of Amorphophallus titanum and analyze the pattern of its distribution in Muara Hemat Village, Kerinci Seblat National Park. The data were collected with 3 hectars of sampling area divided into 3 lines (transect) measuring 10 m x 1000 m. The distance between each transect is 1000 m. Each transect is divided into plots measuring 10 m x 10 m, resulting in a total of 300 plots. The dispersal pattern of A. titanum was analyzed by Morisita Index formula. Based on research that has been done, the population of A. titanum were 83 individuals which were located in 51 of 300 research plots. The density of A. titanum was 27.67 individuals/hectar. Through the Morisita index calculation, it is known that the distribution pattern of A. titanum in Muara Hemat Village is clumped (Ip = 0.50).

Abstract

Certified sustainable community forests in Indonesia continue to grow in number for the Forest Stewardship Council (FSC) scheme. At least three aspects have been fulfilled namely, sustainable production, protected ecosystems, and social contribution. However, the problem of 'need cutting' in community forests has the potential to hamper forest management in terms of timber harvesting. Three FSC certified community forest management units in East Java, Enggal Mulyo, KSU KAM KTI, KSU Bromo Mandiri KTI, demonstrated this challenge through evaluating the log harvest records, discussions with managers and farmers, and field observations. Harvesting plans are only based on periodic tree inventory data that does not take into account the farmers' harvest needs, such as weddings or celebrations. Therefore, all annual timber production targets cannot be achieved, indicating that need harvesting and delayed logging are also still visible in internationally certified sustainable forest management. Support from managers and parties is still needed so that the management plan can be implemented properly. The owner of the FSC scheme also needs to evaluate their standard requirements for implementing timber harvesting on a more realistic scale of community forests.

Abstract

Data and information on forest health conditions can be obtained by periodically monitoring forest health. Regular forest health monitoring can support the achievement of sustainable forest management so as to guarantee the quantity and quality of forests. This study aims to obtain the value of the status of forest conditions that are managed by the Sustainable Community Forestry System (SHK) group. This study uses the Forest Health Monitoring (FHM) method with a sample measuring plot in the form of six FHM clusters. The results showed that the value of the status of the condition of the forests managed by the SHK Lestari group was in the bad criteria (clusters 1, 2, 3, and 6) and good (clusters 4 and 5). Thus, the status of forest conditions managed by the SHK Lestari group is on average bad. Keywords; Forest health monitoring, SHK Lestari, Status values

Abstract

Beringin Jaya Community Forest is one of the community forests in Tanggamus Regency, Lampung Province. The economy of the forest farmers highly depends on the productivity of the forest land. One of the things can be done to improve forest productivity is by doing maintenance in the forest stand. Therefore, research regarding forest maintenance done by forest farmer is significantly important to be conducted. The aim of the research is to figure the maintenance system done by the farmers. The data is collected through direct observation and interview towards 72 respondents. The study shows that 72 farmers (100%) conduct weeds clearing and pruning, while transplanting conducted by 65 farmers (90.3%), 51 farmers (70,8%) apply fertilizer, 24 farmers (33,3%) doing tillage, 14 farmers (19,4%) do pest and disease management. Transplanting technique while they use is by planting seedlings in the hole sized 40cm x 40cm x 40cm during wet season. Tillage is done by tilling the soil around the tree with diameter 20–50 cm, mostly it is done during the dry seasons. Weeding was done conventionally and chemically, 3–4 times per year. Organic and chemical fertilizer is used by the farmers which applied in the wet seasons. Fertilizing is being done by buried the fertilizer around the plants. In the other hand, unproductive branches will be pruned, the pruning was usually done in the wet season. Pest and Disease management conducted by the farmers were by making a trap or hunt the pest down. Keywords: maintenance, community forest, forest farmers.
