Abstract

Purun is one of the Non-Timber Forest Products that comes from peat swamp forests. This plant grows wild and is used by communities around the forest to make various handicraft products as a side income. This research aims to analyze Purun's prospects as an NTFP to support the economy of communities around peat swamp forests. There are three research locations, namely Petuk Katimpun Village, Kalampangan Village, and Tumbang Nusa Village. The sampling method was purposive sampling, namely people who were purun craftsmen and lived close to the purun growing area. Data analysis uses SWOT analysis. The research results show that the prospect of Purun as a non-timber forest product (NTFP) to support the economy of communities around peat swamp forests in the three research locations is in a strategic position, namely at the cut-off point (0.569; 0.684), precisely in the first quadrant (I). The alternative strategy used is the SO (Strength and opportunities) strategy, namely utilizing Purun NTFPs; creating markets and promotions; increasing Human Resources (HR) through training and forming Micro, Small and Medium Enterprises (MSME) groups. Based on these results, the policy that is expected is to support the use of Purun NTFPs by the community, by providing counseling, training and outreach so that Purun Purun products can compete with other NTFP products.

Abstract

Penelitian ini dilakukan untuk menguji kualitas pelet kayu dengan komposisi campuran limbah serbuk kayu Bangkirai berbanding Meranti Merah. Perbandingan komposisi berturut-turut yaitu 100:0, 75:25, 50:50, 25:75 dan 0:100, masing-masing tiga kali pengulangan. Hasil penelitian menunjukkan nilai kadar air, kadar abu, kadar zat mudah menguap, kadar karbon terikat dan nilai kalor masuk dalam standar SNI untuk semua perlakuan, kecuali nilai kerapatan. Nilai kadar abu dan nilai kalor masuk dalam standart Prancis (ITEBE), kecuali kadar air dan kerapatan. Pada standar Swedia nilai kerapatan, kadar abu dan nilai kalor memenuhi standar, kecuali nilai kadar air. Hasil analisis ragam perlakuan komposisi serbuk kayu menunjukkan perbedaan yang nyata hanya pada nilai kerapatan dan nilai kalor. Kerapatan dan nilai kalor terbaik pada komposisi Bangkirai dan Meranti Merah 100:0, diikuti dengan komposisi 75:25. Perbandingan komposisi bahan ternyata tidak mempengaruhi kualitas pelet, karena perlakuan terbaik pada komposisi 100% kayu Bangkirai. Pemanfaatan limbah Kayu Bangkirai prospektif untuk dijadikan pelet kayu dari segi kualitas, baik untuk konsumsi dalam negeri maupun ekspor, namun perlu perhatian dalam penanganan serbuk kayu untuk menurunkan kadar air, sehingga dapat meningkatkan nilai kerapatan.

Abstract

Community forests are one of sustainable development strategies that provides a variety of environmental services, especially to meet subsistence needs and provide community income. The important value of community forests can be seen from the contribution of non-timber forest products (NTFPs) to community's income. Therefore, it is important to conduct studies to create programs for the development of community forests. This research aims to identify various types of NTFPs in the Buntoi Village Community Forest, Central Kalimantan and their economic contribution to community income. This research uses a case study approach by combining qualitative and quantitative methods. Data was collected through field observations and interviews with respondents selected purposively. This research found 14 types of NTFPs and a contribution of Rp. 29,247,097/year/respondent or Rp. 2,437,258/respondent/month. The conclusion that can be drawn is that community forests are able to provide a significant contribution to income so they need to be developed further so that they can support increased community welfare.

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.
