Abstract

This study aims to understand physical and mechanical traits of kawui wood after storage period of five years. Further, this study aims to understand how the five years storage period influence the quality of kawui wood, and thus, it ensures the expected standard quality of the wood after longer term of storage. The method used in this study is Complete Randomized Design factorial, whereby the first factor is tree. The second factor is the year which are year 1 (2019) and year 2 (2024). Each of the factor is executed within tree repetition. The making of test samples followed the DIN 52-183 and 52 182 standards. The results show that for the density, MoR and MoE parameters of kawui wood with a storage period of five years is a significant effect except for the water content parameter. The average water content value of the research results was 14%, still within the reference design value of SNI 7973: 2013 which sets the water content at 19%. The decrease in density values showed the same tendency as the decrease in MoR and MoE values. The decrease in MoR value with a storage period of five years ranged from 12.5-25%., while the decrease in MoE value with a storage period of 5 years ranged from 3-6% and was included in the E8 quality of SNI 7973: 2013 regulations

Abstract

This study aims to identify diseases and pests, assess the level of stand damage, and compare the level of damage to Balangeran (Shorea balangeran (Korth.) Burck) and Meranti copper (Shorea leprosula Miq) stands on the Green Campus of Palangka Raya University. Sampling was conducted using purposive sampling method with 5% intensity with a total of 150 stands for balangeran and 135 stands for copper meranti. Sampling in the field used a diagonal pattern by taking five sides of each stand plot. The results showed that the dominant pests attacking balangeran and meranti copper stands were green grasshoppers (Oxya chinensis), termites (Coptotermes curvignathus Holmgren), leaf bugs (Pentatomidae), moth caterpillars (Labeda nobilis), bag caterpillars (Metisa plana), for diseases, namely leaf spot (Coletotrichum sp), leaf spot (Pestaliopsis sp), leaf spot (Phomopsis vexans). The frequency of attack and intensity of pest and disease attack from both planting locations showed that the planting area in the nursery for pests was higher than the seed garden area while for diseases in the seed garden area was lower than the nursery area

Abstract

Non-Timber Forest Products, such as Nyamu/Breadfruit Bark (Artocarpus altilis), are utilized by the Dayak community as the primary material for making traditional attire. Complementary items like Sumping and Lawung are also crafted. In the past, these Lawung and Sumping were simple, with minimal ornamentation or accessories. However, as demand has grown, decorations such as sequins, beads, and embroidery have been added. Despite these enhancements, the designs still reflect the distinctive characteristics of the Dayak tribe in Central Kalimantan. The challenges faced by the partners involved in this initiative include Partners have no prior experience in making Lawung and Sumping, although these products are in high demand; As educators in the Non-Formal Education program, the partners feel it is crucial to provide entrepreneurial skills to their students; and Partners need to understand the techniques for applying accessories such as sequins, beads, embroidery, and bird feathers to enhance the aesthetic appeal of bark-based materials. The primary challenge that needs immediate attention is transferring knowledge to enhance participants' skills so they can create job opportunities, design innovative and attractive crafts, and produce high-quality products that align with market demands. The use of simple and reliable technology is introduced to participants, emphasizing that bark can be transformed into desirable products instead of being wasted. This results in unique, distinctive, and beautiful items. Implementing sewing machines and techniques for embellishing bark materials with sequins is a straightforward technological application accessible to all participants. The training benefits education by incorporating aspects of local wisdom into the curriculum for both formal and non-formal education. By introducing regional crafts, participants can explore creativity, innovation, and entrepreneurial opportunities. The products created include Lawung and Sumping with motifs inspired by Bajakah (a traditional plant) and birds, adorned with embroidery, sequins, and bird feathers for the Sumping.

Abstract

Katingan Regency is recorded as one of the regions with a significant production of Non-Timber Forest Products (NTFP), specifically rattan. In managing Community Forests, baseline data containing the potential resources within is required. This rattan potential data is used to formulate the Community Forest Management Plan. This study aims to estimate the potential of rattan in the Community Forest area of Tumbang Habangoi, Katingan Regency. Forest stand stratification was processed using the Forest Canopy Density (FCD) Model. The FCD is a vegetation index transformation developed by Rikimaru from the International Tropical Timber Organization – Japan Overseas Forestry Consultant Association (ITTO – JOFCA) and P.S. Roy from the Indian Institute of Remote Sensing in 1999, using Landsat TM imagery data as the primary input. The FCD results can distinguish canopy coverage with an accuracy of nearly 90%, enabling differentiation in canopy density. The FCD will be evenly distributed across 30 sample plots in the field. The number of sample plots, set at 30, is based on literature suggesting that a sufficient number of clustered image samples is around 25 evenly distributed sample plots. The rattan in the Community Forest of Tumbang Habangoi has an estimated total potential of approximately ±7,786.4 tons, averaging ±4.2 tons/ha. The growth of rattan heavily depends on the structure of the forest stands and the climbing trees supporting the rattan. The Forest Canopy Density Model is effective in mapping the horizontal structure of stands in Lowland Tropical Forests

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

The use of wood requires wood conditions with low air content (KA) according to the environment. Its position can influence wood properties in the trunk. The objectives of this research are a) to analyze the natural drying properties, namely the drying rate in the radial direction of tumeh wood, and b) to analyze natural drying defects. The method used refers to Hidayat and Karnasudirdja 1987. The parameters measured are natural drying properties (drying rate) and drying defects. Statistical analysis used t test. The results show that the natural drying rate pattern is greater near the liver than near the bark. The location in the radial direction of the wood (near the bark and the heart) has no significant effect to the natural drying of tumeh wood. The natural drying defect found were surface check and end check. Further research into the natural drying properties of tumeh wood in different diameters is necessary to utilize the wood effectively and efficiently.

Abstract

The rasau plant grows in riparian forest areas within tropical peat swamp forests. It is a lignocellulosic material with potential as a raw material for particleboard. Before being used as a raw material, a feasibility study must be conducted on the rasau plant (Pandanus helicopus). The stems of rasau were analyzed for cell dimensions, cell proportions, chemical composition, and physical and mechanical properties. The results indicate that the fiber dimensions and proportions, as well as the physical and mechanical properties, demonstrate that rasau stems are suitable for use as a raw material for non-structural particleboard. Rasau can be utilized as a raw material for particleboard, provided the particles undergo cold water soaking and use phenol-formaldehyde or melamine-formaldehyde resin adhesives, followed by hot pressing

Abstract

Local wisdom is knowledge and practices passed down by a group that serves as an identity and strategy carried out in meeting the needs of daily life. This research highlights the local wisdom of the Dayak Ngaju people of Buntut Bali village, Katingan, who use traditional farming systems for their livelihoods. This traditional farming system can not only be adapted to local conditions, but more importantly is able to contribute to food security and local ecological sustainability. The research methodology used was descriptive qualitative method with a field approach through observation and in-depth interviews with farmers who are members of the “Pamaran” farmer group. Data collected included crop types, cropping patterns and constraints faced by farmers. The results revealed that the Ngaju-Dayak community's cropping pattern is a polyculture farming system consisting of annual and seasonal crops. There are 15 types of annual plants dominated by durian and banana. While 14 types of annual crops are managed in rotation and intermittently, according to soil conditions and seasons. Simple economic formulas about the income obtained from the application of traditional agriculture show that crop yields cannot be guaranteed to be profitable, because the results are influenced by how many trees bear fruit that are seasonal, such as durian, langsat and rambutan. In traditional farming systems, there are also often wild plants that are used by the community that cannot be planted but are very popular as vegetables, such as: teken parei. Local wisdom in traditional farming systems needs to be maintained for the preservation of local species and increased innovation in the maintenance and improvement of crop products, especially fruits

Abstract

The Ecological Sensitivity Level of Tahura Area of Palangka Raya City is dominated by Very Sensitive (76.81%) which indicates that this part of the area has high biodiversity potential with its unique biogeophysical ecosystem, so serious efforts and attention are needed to protect and preserve it. Land use intervention in the Tahura area is dominated (57.98%), indicating the high intervention of human activities in the form of land use in this part of the area. The gap level of Tahura Area is dominated by Very Sensitive, Land Use Intervention (39.87%). This indicates that this part of the Tahura Area has a very high ecological sensitivity and is vulnerable to intensive human activity intervention, resulting in a very high risk of damage to its natural ecosystem. While the level of gap in the Very Sensitive, No Land Use Intervention area (36.94%) indicates that this part of the Tahura Area has very high ecological sensitivity and relatively minimal human intervention, and is at low risk of damage to its natural ecosystem. Based on this, the ecological sensitivity and gap of the Palangka Raya City Forest Park (Tahura) area indicates the vulnerability of the area to high intervention of human activities and the risk of damage to natural ecosystems, as well as the loss of biodiversity if no immediate mitigation and rehabilitation measures are taken, as well as proper planning and governance of the area
