Abstract

Non-Timber Forest Products (NTFPs) have great potential in supporting the economy of forest communities through sustainable utilization based on local wisdom. This study aims to analyze the potential of NTFPs, identify value chains, and formulate development strategies to improve the welfare of forest communities. The study was conducted in three villages: Tuwung Village, Luwuk Kanan Village, and Sei Gohong Village in Central Kalimantan. The research method used a qualitative and quantitative approach through interviews, observations, Focus Group Discussions (FGDs), and market analysis. The development strategy analysis used SWOT. The results showed that NTFPs: rattan (Calamus spp.), stingless bee honey (Trigona sp.), and medicinal plants: bajakah (Uncaria gambir Roxb.), Dayak onion/lemba onion (Eleutherine bulbosa) are the types of NTFPs most dominantly utilized by the community, both for personal use, sale, or partly for personal use and partly for sale. However, the NTFP value chain is still weak in post-harvest aspects, processing, and market access. The SWOT analysis results show that the NTFP product development strategy falls into Quadrant IV (defensive strategy). This defensive strategy involves rationalizing activities, focusing on one or two potential superior products. Tuwung Village focuses on stingless bee honey, Luwuk Kanan Village on rattan, and Sei Gohong on medicinal plants (bajakah, Dayak onions/lemba onions). Furthermore, strengthening community capacity, improving group institutions, diversifying products, and supporting policies are key to realizing a sustainable NTFP-based economy. This study confirms that value chain development and appropriate strategies for selecting NTFP products are crucial for promoting inclusive and sustainable economic development for communities surrounding forests in Central Kalimantan.

Abstract

The study aims to determine the water content and specific gravity and analyze both on the potential utilization of pulai coppice wood. The study was conducted at the Forest Products Technology Laboratory, Forestry Department, Faculty of Agriculture, Palangkaraya University. Pulai coppice wood material was taken around the Palangka Raya University Campus, tree diameter 34cm, branch-free height 7m. Using a 2-factor factorial Randomized Block Design with 3 levels, the first factor is the axial direction, namely the base, middle and tip. The second factor is the radial direction, namely near the heart, between the heart and the bark and near the bark. The parameters observed were green water content, air-dry water content, green specific gravity, air-dry specific gravity and oven-dry specific gravity. The results showed an average value of green water content of 84.75%, air-dry water content of 18%, green specific gravity of 0.29%, air-dry specific gravity of 0.30% and oven-dry specific gravity of 0.31%. All parameter values ​​​​resulted from the research on pulai coppice wood were lower than the values ​​​​of the main stem pulai coppice wood from previous studies. In the axial direction, all parameter values ​​show an increasing pattern from base to tip, except for the wind-dry moisture content, which shows the opposite pattern. In the radial direction, the values ​​tend to be uniform, except for the green specific gravity, which decreases from the outside (near the bark) to the inside (near the heart). The results of the analysis of variance indicate that all parameters influence the axial direction, while only the green specific gravity influences the radial direction. This indicates that the axial factor dominates the physical properties of pulai coppice wood. The interaction factors that influence this are green water content and oven-dry specific gravity. Based on the specific gravity and wind-dry moisture content values, pulai coppice wood is lightweight and adapts quickly to its environment, thus quickly achieving dimensional stability. This pulai coppice wood is suitable for light construction and interior use.
