Abstract

Nyaru Menteng Urban Forest is ±100 hectares of Others Use Area (APL) and information on its biodiversity is limited. This study aims to assess biodiversity and forest conditions. Flora data were collected using the quadrat transect method and fauna data using a combination of Visual Encounter Survey and Point Count methods. The species composition of the flora is no less than 20 species, dominated by the Dipterocarpaceae family with density of seedling 6,170 individuals/ha, saplings 1,472 individuals/ha, poles 330 individuals/ha, and trees 224 individuals/ha indicating sufficient natural regeneration and forming an inverted J curve. The highest IVIs were Combretocarpus rotundatus, Shorea balangeran, Cratoxylon glaucum, Campnosperma coriaceum, and Palaquium leiocarpum. Flora biodiversity shows high species diversity, high species richness, low species dominance, and almost even species distribution. Fauna species composition is 45 species with 6 species of mammals, 25 species of avifauna, 7 species of herpetofauna, and 7 species of insects. Faunal biodiversity showed moderate species diversity, low species dominance, low species richness (except avifauna), and moderate species evenness. It can be concluded that Nyaru Menteng Urban Forest is very worthy of being maintained as an exotic and unique peat swamp forest, because it has high biodiversity with abundant natural regeneration, good individual species evenness, stability and balance of the forest ecosystem

Abstract

Macroinvertebrates are organisms that live on the bottom of the water and have different levels of sensitivity to changes in conditions. The use of macroinvertebrates as indicators is due to their high sensitivity to changes in water quality, including the EPT group (Ephemeroptera, Plecoptera, and Trichoptera). In addition, the presence of EPT is influenced by the source of river pollution. This study was conducted at three monitoring stations (upstream, midstream, and downstream) located in Pusur River. Each station had ten repetitions of sampling, followed by the calculation of the macroinvertebrate assessment index value. The results of the study showed that at the Upstream station the level of pollution was light, at the Middle station the level of pollution was light, and at the Downstream station the level of pollution was moderate.

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.

Abstract

Rattan is a type of palm tree that grows in tropical climates. Rattan currently has a low price level with limited rattan raw materials. However, rattan collectors continue to buy rattan from farmers and provide jobs for their workers with low wages, but rattan workers continue to work. Based on this background, research was conducted which aimed to analyze the level of worker welfare based on the Regional Minimum Wage (UMR) and the Central Statistics Agency (BPS); as well as knowing workers' perceptions of their level of welfare at UD Putra Harapan. The data collection method uses observation and structured interviews with key respondents. Data analysis uses a Likert Scale to measure respondents' perceptions and uses analysis of worker welfare levels based on UMR and BPS. The research results show: the level of welfare of workers does not meet the minimum wage individually, but if we look at each household, the respondent's income exceeds the minimum wage. Meanwhile, based on BPS, the level of worker welfare is included in the high classification. The perception of rattan workers at UD Putra Harapan states that their level of welfare is relatively good.
