Abstract

The research aims to determine the quality of bio-pellets from Kawui wood branches using three levels of adhesive percentage. The materials used are branch wood from Kawui and tapioca flour adhesive. The research method employs a Completely Randomized Design with a single factor, namely the adhesive percentage. The factor consists of three levels: adhesive percentages of 10%, 20%, and 30%, with five repetitions. The results indicate that the adhesive percentage does not significantly affect the ash content, volatile matter content, and fixed carbon content, except for calorific value and density. The quality of bio-pellets meets the SNI 8675-2018 standard for household and industrial scales at all adhesive percentages, except for volatile matter content and fixed carbon content. According to French standards, the quality of bio-pellets meets the standards for every parameter except calorific value at the 30% adhesive percentage. According to Swedish standards, the quality of bio-pellets meets the standards for every parameter except moisture content at the 10% adhesive percentage and calorific value at the 30% adhesive percentage. Overall, the 20% adhesive percentage exhibits the best quality

Abstract

The aim of this research is to determine the influence of mixture rasio of cement/bamban particles on the quality of the cement boards. This research was conducted by four mixture rasio cement/bamban particles (w/w) that was 1.25/1, 1.5/1, 1.75/1 and 2/1. Bamban particles was immersion on hot water (boiling at 100°C) for 3 hours to remove the extractives compounds. The mixture ratio between cement and bamban particles was compressed for 1 hour at a pressure of 30 bar, followed by manual pressure (clamping) for 24 hours. The physical and mechanical properties of cement boards was conducted according to SNI 03-2104-1991 for wood-wool cement boards. The results of the study show that mixture rasio cement/bamban particles has a very significant effect on the quality of the resulting cement boards.

Abstract

Traditional medicine knowledge of the Dayak Ngaju tribe in Kahayan Tengah District, Pulang Pisau Regency still utilizes and uses plants as one of the traditional medicines to cure diseases and maintain health. The study aims to inventory medicinal plants of the Dayak Ngaju tribe in Kahayan Tengah District, document and explore local wisdom related to their use. Qualitative methods through in-depth interviews were used to obtain primary data. Respondents were selected using purposive sampling techniques with the criteria being people working as traditional healers as many as 5 people from selected villages/sub-districts as key figures. The results of the study showed that the types of plants used as traditional medicine by the Dayak Ngaju tribe in Kahayan Tengah District, Pulang Pisau Regency amounted to 130 types including 56 families, the dominance of the most types of plants for treatment from the Myrtaceae family 9 types (6.9%). The most widely used plant habitus is in the form of trees 50 types (38%), the most widely used plant parts are in the form of leaves as many as 79 species (32%). The most common way of processing/using plants is by boiling and drinking them, as many as 107 types (58%), and the most widely used type of plant as medicine based on disease classification is chronic disease, as many as 174 types (51.03%).

Abstract

Research has demonstrated the treatments using sawdust–cement ratios of A1 (1:1.5), A2 (1:2), A3 (1:2.5), and A4 (1:3) in the manufacture of red meranti wood particle cement boards based on the SNI 03-2105-2006 standard. The results showed that the physical and mechanical properties of red meranti sawdust cement boards met the standards for moisture content, density, and thickness swelling. However, the modulus of elasticity (MoE) and modulus of rupture (MoR) did not meet the SNI 03-2105-2006 requirements. The analysis of variance indicated that the sawdust–cement ratio treatments had no significant effect on moisture content, density, and thickness swelling, but had a significant effect on the modulus of elasticity (MoE) and modulus of rupture (MoR), with the best treatment being A1 (1:1.5). The quality of the red meranti sawdust cement board falls under the ordinary type 1 particle cement board with a thickness of 13 mm and medium density, and is therefore recommended for non-structural uses such as interior partition walls, ceilings, decorative purposes, and tabletops.

Abstract

Terantang is commonly found growing in the peat swamp forests of Central Kalimantan. It holds significant economic value in the wood processing industry; however, it has low durability, requiring preservation treatments to enhance its wood quality. This study aims to analyze the impact of Gelam wood liquid smoke concentration and the radial direction of Terantang wood on its physical properties, particularly wood weight and specific gravity, after being stored outdoors under shaded conditions for 5 weeks. A factorial Completely Randomized Design (CRD) was employed, incorporating two factors: liquid smoke concentration (0%, 10%, 20%, and 30%) and radial direction of the wood (near the bark, middle, and near the pith). The data were analyzed using ANOVA, followed by Tukey’s HSD test to determine significant differences between treatments. The results indicated that increasing the concentration of liquid smoke significantly enhanced both the wood weight and specific gravity. The 30% liquid smoke concentration produced the highest increase in specific gravity (0.5240 g/cm³). The radial direction of the wood also had a significant effect, with the near-pith section showing higher specific gravity. The interaction between liquid smoke concentration and radial direction significantly influenced the wood weight. These findings suggest that Gelam wood liquid smoke is an effective natural preservative that can significantly maintain the physical quality of Terantang wood stored outdoors under shaded conditions for 5 weeks, specifically in terms of wood weight and specific gravity. This method shows potential for use in sustainable wood processing industries.

Abstract

This research aims to Identify each type of plant that has the potential to be used as medicine in Petak Puti Village; Describe the use and processing methods of plants that have the potential to be used as medicine. The research uses a qualitative method with a descriptive research design. Observation, to obtain information about the initial stages of the research, was conducted to seek information about traditional medicine that utilizes medicinal plants in Petak Puti Village. The informant selection technique used the purposive sampling method, carried out by selecting informants for certain considerations, in this case, the person who is considered to know the most about the situation in the village. The determination of informants purposively is assumed that the selected informants represent a homogeneous community, consisting of main informants (key informants) to be interviewed such as the village head, traditional leaders and immigrants who are married to village residents. While the basic informants are village members, traditional members and residents outside the village who have knowledge about the village. The local wisdom of plant species is very significant in the views and perceptions of the community in meeting basic human needs. The Dayak Ngaju Katingan community is highly dependent on natural resources to meet various daily needs. Most of the community's income comes from forest plant products. The diversity of plant species can provide food products for the community, produce various types of plants for consumption as a supplement for the Dayak community and generate alternative sources of income, such as used as food, medicines, fermentation, tonics, cosmetics, building materials and other materials, which can provide important nutrients and vitamins as supplements for the community, and can provide a buffer in times of food shortages. In addition, existing plant species have great potential to be developed and cultivated into new plants and provide genetic resources and conduct selection.
