Abstract

The purpose of this study (a) determine the composition and structure of vegetation based on the growth rate (tree, pole, sapling, seedling) in each Permanent Sample Plot (PSP); (b) to calculate the potency of biomass and carbon in vegetation trees level, poles and sapling on each PSP. The results showed that the number of vegetation species found in PSP-1 as many as 47 species with 28 family and PSP-2 of 33 species with 24 family. The vegetation of species that dominate based on the level of growth (tree, pole, sapling, seedling) in the PSP-1 consists of : Gerunggang (Cratoxylum arborescens (Vahl) Blume) and Jambu-jambu (Syzigium sp). In PSP-2 of vegetation species that dominance Tumih (Combretocarpus rotundatus (Miq.) Danser) and Jambu-jambu (Syzigium sp). The structure of the vegetation horizontally in the PSP-1 and PSP-2 dominated the vegetation of the small diameter and structure of the vegetation vertical in the dominance of vegetation including the stratum D. The average value the species diversity indexs vegetation tree level, pole, sapling and seedling in PSP-1 at 2.09 included in the category of “medium” and in PSP-2 of 1.83 which is included in the category of “low”. The potency vegetation biomass total in PSP-1 and PSP-2 respectively 152.69 tons/ha and 122.93 tons/ha as well as the potency carbon vegetation total in PSP-1 and PSP-2 respectively 71.76 tons/ha and 57.78 tons/ha.

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

Rural communities often rely on medicinal plants for primary healthcare; however, thier knowledge of the diversity and use of these plants is not well documented. This study aims to identify medicinal plant species, their modes of use, and to support the preservation of local cultural wisdom. The research is conducted in the Tangkahen Village Forest, Central Kalimantan, using a 100% exploratory inventory method. Observations are made along three transects representing dense, moderate, and sparse forest cover. Information on plant utilization were obtained through interviews with local traditional healers. This study found 108 individual medicinal plants, representing 16 species from 13 botanical families. The most represented families are Orchidaceae (19%) and Auriculariaceae (13%), with others such as Araceae, Lauraceae, Apocynaceae, and Fabaceae comprising smaller percentages. These plants are used to treat 22 types of ailments, including diabetes, cancer, cardiovascular disease, digestive disorders, and for cosmetic purposes. Preparation methods includes decoction, infusion, topical application of pounded material, and direct consumption. The most commonly used plant parts are leaves, stems, roots, sap, and bark. Some involves combination of 2–3 species. The availability of these plants supports local health needs and presents opportunities for economic development through further processing, thereby indirectly contributing to food security. Further pharmacological studies are needed to analyze their compounds. Cultivation efforts are also essential to ensure the long-term sustainability of these medicinal resources.
