Abstract

Red Jabon naturally, grows in the lowland Sulawesi forest to the mountains. One of the locations where the Jabon Merah distribution is found is in the KPH Sivia Patuju management area. Plot determination in this study used a systematic sampling with random star method, with a plot size of 20 m X 125 m as many as 30 plots and a distance between plots of 50 meters. The results of the field data will be entered into a tally sheet, then to calculate the potential, a formula is used to interpret Jabon's potential and allometrics to calculate its biomass by statistical analysis. Based on the results of direct research in the field and analysis of data that has been carried out, the data obtained are the estimation of the potential volume of the Red Jabon tree (Anthocepalus macropillus) which is in the Limited Production Forest (HPT) of Tatari Village, West Tojo District, Tojo Una-una District, which is 198,873, 2 m³ and volume 267.64 m³/ha. And estimation of Biomass found in Jabon Merah stands (Anthocepalus macropillus) overall biomass of 112,870.2 tons and Biomass on average 151.5 tons/ha.

Abstract

Efforts to preserve semar bag plant species are absolutely necessary so that their existence is maintained. However, the problem faced is limited data and information on habitat factors and the suitability of Semar bag habitats that are most suitable as Semar bag plants. This research was conducted for 3 (three) months from March to May 2018, which is located in the Rorekautimbu Mountain Climbing Route in Central Sulawesi, using a purposive sampling method based on the height of the research location where the height of the research pathway starts from 1,700 m.dpl to 2,500 m.dpl. The height of the mountain was then made into three classes with an altitude of 1,700 masl-1,950 masl, 1,950 masl-2,200 masl and> 2,200 masl. The parameters used to find the suitability of Nepenthes spp habitat are height, slope, vegetation density, and distance from the river. From the results of the research and spatial analysis of all the variables, it can be seen that the most suitable habitat of Nepenthes is in class 238-325 with a total of 43 Nepenthes and an area of 388 Ha, quite appropriate to be in the 149-237 class with a total of 5 Nepenthes and the area reaches 654 Ha, while the less suitable are in the 60-148 class with an area of 72 Ha.Keywords: Habitat, Semar Bags (Nepenthes Spp) and Rorekautimbu

Abstract

Community Forestry (HKm) is a state forest aimed at empowering, increasing the capacity and independence of local communities to obtain the benefits of forest resources optimally and fairly. Community forest management is one solution to improve community welfare and is a concrete form of community participation in the implementation of forestry development. Community participation in community forest management is one of the social capital that has been developed integratively through various creative activities in order to utilize natural resources sustainably and sustainably. The purpose of this study was to determine the level of participation of community forest farmers in Labuan Toposo Village, Labuan Subdistrict, Donggala Regency. The method used in this study is descriptive method. Data collection is done by observation or direct observation in the field and conducting interviews with farmers (Respondents). The population in this study were farmers in Labuan Toposo Village. Sampling in this study using purposive sampling method or with intentional namely by selecting farmers who are members of the Sisere Jaya Forest Farmer Group with 30 respondents. The research data analysis was used to answer the research objectives that had been made using quantitative descriptive and qualitative descriptive analysis. The level of participation in Community Forest Management is classified as high with a percentage of 76.67%, and the level of participation of farmers in community forest management is at the planning stage of entering the Partnership level. Power is channeled between government negotiations and farmers. The government imposes farmers as work partners, they together work together in compiling and implementing work programs.Keywords: Community Forestry, Participation, Forest Farmers, Forest Management

Abstract

High population growth has become an important factor in the utilization of forest and land resources. Along with the increase in population growth, the fulfillment of life necessities is also increasing, this condition has directly or indirectly been a causal factor and a trigger factor for pressure on forest and land resources. Identification of encroachment area distribution is needed to formulate strategies for handling and preventing encroachment, so that prevention and monitoring activities can run more effectively and efficiently. Educational forest is an educational facility that aims to support and improve quality. Very important information is needed in the context of educational forest management. Based on data from the Environmental Agency of Donggala Regency (2013), the forest area in Donggala Regency is 284,101 Ha. However, the area of forest cover continues to decline. This is partly due to the activities of rural communities around the forest, especially in the Tadulako University Education Forest area. The method used in this study is the scoring and overlay using ArcGis 10.0 software, as well as the field survey method to obtain coordinates. Based on the results of research conducted in the Tadulako University Forest Education area, it is known that most areas in educational forest areas tend to be prone to encroachment activities. The results of the analysis showed that the area included in the category of high hazard vulnerability was 433.08 ha or 23.88%, medium encroachment level was 839.56 ha or 46.30%, and the vulnerability level low  was 540.59 ha or 29.81%.Keywords : Encroachment, Educational Forest, Scoring, Overlays, Encroachment distribution map
