Abstract

An investigation of the recruit, survivorship and growth of naturally regenerating tree species on canal bank was conducted to  select tree species which are suitable for preceding planting in drained and burnt peat swamp lands in  Central Kalimantan, Indonesia.  Top of  the canal bank were open, with greater soil moisture  deficit and higher soil temperatures than on the next intact forest floor. The abundant  trees were asam-asam (Ploiarium alternifolium),garunggang (Cratoxylon arborescens) and tumih (Combretocarpus rotundatus). New regeneration of these trees on the canal bank was confirmed during this investigation and mortality was very low. These results indicated that P. alternifolium,C. arborescens and C. rotundatuswere tolerant of intensive radiation, soil drought and high soil temperatures during germination. The annual height increments  were 189-232  cm y-1 (P. alternifolium),118-289  cm y-1  (C. arborescens)and 27-255 cm y-1   (C. rotundatus); thus, these three species could be classified as fast-growing with tolerance to open and dry conditions.  Such characteristics were important to avoid competition with herbs, ferns,and/ or climbers. The results·suggest that P.alternifolium,C. arborescens and C. rotundatusare suitable for preceding planting for the rehabilitation of the disturbed peat swamp forests of Central Kalimantan.

Abstract

Tengkawang (Shorea pinanga Scheff) is an endemic species from the genus Shorea that holds significant ecological and economic value, particularly in tropical regions like Indonesia. This plant is well-known for its seeds, which can be processed into valuable vegetable oil widely used in the cosmetic, food, and pharmaceutical industries. However, the existence of tengkawang trees is increasingly threatened by deforestation, illegal logging, and land-use changes, necessitating conservation efforts and optimal seedling cultivation. During the nursery stage, proper care of tengkawang seedlings is crucial to ensure healthy and ready-to-plant seedlings. One of the critical factors influencing the success of seedling cultivation is the provision of adequate nutrition. The use of liquid organic fertilizer (LOF) is an appealing alternative to enhance seedling growth as LOF contains various essential nutrients easily absorbed by plants, along with microbes that improve soil structure and accelerate organic matter decomposition. LOF is considered more environmentally friendly than chemical fertilizers, reducing the risk of soil and water contamination. This study aimed to test the application of liquid organic fertilizer in enhancing the growth of tengkawang seedlings and to evaluate the growth response to different LOF dosages in nursery conditions. The method used was a Completely Randomized Design (CRD) with four treatments and three replications. Each treatment involved five seedlings, resulting in a total of 60 tengkawang seedlings. Data analysis was conducted using Analysis of Variance (ANOVA). The results showed a 100% survival rate for tengkawang seedlings, classified as excellent. The best LOF dosage was 20 ml, which resulted in the highest growth in height and diameter. The shoot-to-root ratio was also classified as good, falling within the NPA (shoot-to-root ratio) range of 1–3. Soil analysis indicated that the soil pH was acidic, total nitrogen was moderate, organic carbon was low to moderate, and the nutrient content of phosphorus (P) and potassium (K) was very high. The application of 20 ml LOF is recommended for the propagation of tengkawang seedlings (Shorea pinanga Scheff).

Abstract

Indonesia has a high biological wealth, including various types of medicinal plants that are traditionally used by the community. This study aims to identify the types of medicinal plants and their use in Sebangau National Park, especially in the Habaring Hurung Resort. The approach used is descriptive qualitative, with an exploratory survey method. Data were collected through field observations, semi-structured interviews with key informants (traditional leaders, shamans, and local knowledgeable residents), and visual documentation. Research on medicinal plants in the Habaring Hurung Resort, Sebangau National Park, successfully identified 23 species of medicinal plants used in the traditional healing practices of the local community. The species are spread across 16 families, as well as one unidentified species (pari laki) with a dominance of the Lauraceae and Arecaceae families with the most widely used plant parts being the roots, bark and fruit. These findings indicate the great potential of Sebangau National Park as a source of medicinal plants and the importance of preserving the traditional knowledge of local communities

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

This research focuses on the assessment of soil macrofauna in gold mine tailing storage facilities (TSF) at PT Kasongan Bumi Kencana. The study aimed to analyze the physical and chemical properties of the soil, identify soil macrofauna, and evaluate their diversity in TSF Mirah I (7 years old) and TSF Mirah II (1 year old). Using a descriptive-quantitative approach, 38 subplots were established within each TSF, and data on macrofauna were collected, analyzed, and presented through descriptive statistics and species diversity index calculations. The results revealed that both TSFs exhibited low organic matter content. Mirah I TSF harbored 15 families with 172 individuals, primarily dominated by the Trigoniulidae (millipedes) family. In contrast, Mirah II TSF contained 14 families with 120 individuals, mainly dominated by the Formicidae (black ant) family. The diversity index for Mirah I TSF was moderate (H’=1.9911), similar to Mirah II TSF (H’=1.8665). These findings highlight the potential of soil macrofauna as bioindicators for assessing tailing quality in gold mine operations. Highlights: Examined physical and chemical properties of soil and identified soil macrofauna in two gold mine tailing storage facilities (TSF) at PT Kasongan Bumi Kencana. Utilized a descriptive-quantitative approach and species diversity index to analyze the macrofauna data. Trigoniulidae (millipedes) dominated in Mirah I TSF, while Formicidae (black ant) dominated in Mirah II TSF, with both TSFs showing a moderate diversity index.
