Abstract

The research aimed to assess villagers’s perception of Tumbang Nusa Village on the fire fighting activities (forest and land) by Manggala Agni (or Manggala Agni activities) and the relationship of each community's socio-economic variables with that view. The research is descriptive in nature using scoring, the object of research for the people of Tumbang Nusa Village, is analyzed by the Wilcoxon Rank Test and Chi Square Test. The results showed that there were differences in people's views on Manggala Agni activities between people who lived close to the fire disaster location and people who lived far from the fire location, there was also a relationship between the socio-economic variables of the community and the community's views on Manggala Agni activities.

Abstract

The purpose of this study was to determine the level of preferences and characteristics of orangutan nesting sites in Area Punggualas Sebangau National Park, Central Kalimantan using the strip transect method, a path 1 km long and 25 m wide on each side of the right and left lanes. Nest observations were carried out on 10 transects and the distance between transects was ±200 m. Based on observations of the habitat characteristics and preferences of orangutan nest trees (Pongo pygmaeus) in Punggualas, there are 13 tree species that orangutans like, namely Sagagulang, Bintan, Galam Merah, Kajunjung, Mahalilis, Pampaning, Tatumbu, Rasak, Tutup Kabali, Forest Mangosteen, Nyatoh bawui , Uweh, and Tarantang. The physical tree parameters (total tree height, tree diameter, nest height, and nest position) show X2Hitung > X2Tabel, which means that each variable has a relationship with the frequency of finding significant nests for orangutans to be nests.

Abstract

Community Forestry is one of the schemes in provides access to forest management legally to the community, so community forestry has a role in supporting the sustainability of forest functions. In line with the principles of sustainable forest management, community forestry management is required to maintain a balance of ecological, economic, and social aspects. The purpose of the study was to identify the species composition and estimate the potential biomass reserves, carbon, carbon dioxide (CO2) absorption, and oxygen (O2) production of woody vegetation in the Batu Bulan Community Forest, Tusang Raya Village, West Rungan District, Gunung Mas Regency, Central Kalimantan Province. Vegetation data collection with vegetation analysis techniques using the plot line method. Data from the analysis of woody vegetation was then calculated for the number of species, Shannon Wienner species diversity index (H'), vegetation density, and Important Value Index (IVI). Calculation of vegetation biomass using destructive and non-destructive methods. While the calculation of carbon, CO2 uptake, and O2 production of woody vegetation were each calculated using SNI 7724 (2019), IPCC (2006), and Nowak et. al (2007). The results showed that the number of woody vegetation species found was 31 species included in 19 families with a Shannon Wienner species diversity index value of 2.81 ("medium" category). Tree and pole-level woody vegetation was dominated by Laban (Vitex pubescens Vahl.), while sapling and seedling levels were dominated by Rubber (Hevea brasiliensis) and Palasit (Canarium sp), respectively. The potential reserves of biomass, carbon, CO2 uptake, and O2 production of woody vegetation were 70.12 tons/ha, 32.81 tonsC/ha, 120.96 tonsCO2/ha, and 88.01 tonsO2/ha, respectively.
