Abstract

Conservation forests have a function that is as a preservation of diversity of plants and animals and their ecosystems. The function of the forest should make the conservation forest must be preserved and the health condition of the forest. The health condition of a conservation forest has a great influence on the surrounding ecosystem. Thus to determine the health condition of the forest, one indicator that can be used is the vitality of the tree. Tree vitality is one indicator that can reflect forest health using tree damage parameters and canopy conditions. This study aims to determine the value of the vitality status of conservation forests that are the KTH SHK Lestari land management area to facilitate management decision making in forest management. The results showed from the making of six Forest Health Monitoring clusters in conservation forests classified as good, moderate and bad, obtained the vitality of the conservation forest for tree damage parameters in the good category (2 clusters), moderate (1 cluster) and bad (3 clusters) whereas for the parameters of the overall canopy conditions the clusters are in the good category (6 clusters). Thus the vitality assessment that has been carried out in the conservation forest of Teluk Pandan District, Pesawaran Regency can be used as one indicator in the health of conservation forests.

Abstract

Tannin-based adhesives have drawn interest as a research topic because they can potentially be used in the wood panel industry as an alternative for synthetic adhesives containing formaldehyde. The development of this type of adhesives is expected not only because of the high durability of the panels produced, but also because of their high strength. The aim of this study was to determine the physical and mechanical properties of laminated lumber made from mahogany (Swietenia mahagoni) bark, with the addition of a biopesticide derived from berenuk fruit (also known as calabash fruit, Crescentia cujete) and wood from jabon merah (Anthocephalus macrophyllus). Laminated lumber (2 cm x 5 cm x 40 cm in thickness, width, and length, respectively) was manufactured with two layers of lamina. The physical and mechanical properties of the laminated lumbers were tested based on JAS 234-2007 standard. The result showed that laminated board from TBRF 0% and TBRF 5% adhesives met the standard for delamination test, and all laminated boards fulfilled the standard with regard to moisture content and formaldehyde emission test.

Abstract

Natural coloring and batik techniques by directly printing the shape or motifs of leaves, flowers or fruit, called ecoprint, have been in great demand by the global community. Therefore, the search for types of plants that can produce color continues to be pursued. In this study, the aim of this research is to explore the types of plants from the tree level to the understorey which can provide distinctive colors and motifs to silk fabrics. Part of the plant is collected, especially the leaves, flowers and other parts, especially those that have color and can be perfectly expressed on the fabric. The coloring method used is direct paste method or better known as ecoprint. The mordant treatment used was basic mordant, namely the treatment of soaking the cloth in 10 g / l alum solution for 24 hours. The plant part samples were treated with immersion for 12 hours in 10 g of alum solution plus 30 g of acetic acid. Next, the plant samples are laid out on a cloth and wrapped in clear heat-resistant plastic. After the cloth is wrapped and tied tightly so that it sticks tightly and does not blend in the colors, then steam it for 2 hours. The results of this study showed that of the 88 plant species tested, only 32 species produced the expression of their color and motif from the leaf part, while in flowers there were only two types and one sample from the fruit part. The data from this research can provide information for silk craftsmen as an alternative choice of natural dyes and motifs for fabrics.

Abstract

Forests can provide many benefits both from an ecological, economic, and social perspective. These benefits can be achieved through sustainable forest management. Forest health is one of the criteria for sustainable forest management. Forest health can be assessed through monitoring forest health. One of the ecological indicators that can be used to monitor forest health is an indicator of vitality. This study aims to determine the value of status and changes in vitality indicators by using tree damage parameters and crown conditions. Status values ​​and changes in vitality indicators are needed in order to make different forest management decisions. This research was conducted in Tahura Wan Abdul Rachman (Tahura WAR) Plant and Animal Collection Block using Forest Health Monitoring (FHM). This research was conducted twice, the first measurement was carried out in May 2019, and the second measurement was carried out in December 2020. The results showed that the value of changes in the vitality indicator tends to increase. The first measurement of the status of the vitality indicator 50% is in the "medium" category, 25% is in the "good" category, and 25% is in the "bad" category. The status of the vitality indicator in the second measurement is 50% in the "good" category and 50% in the "bad" category. This change can be caused by an increase in tree damage in each cluster plot. The management decision for the Tahura WAR Plant and Animal Collection Block is that it is necessary to change the management pattern.

Abstract

Biomass waste that has not been utilized properly is wood waste from Sengon (Falcataria moluccana). There is a high potential for these wastes to be used as solid fuel. The quality can be further improved by converting them into charcoal briquettes. This study aimed to determine the effects of adhesive content on the bioenergetic properties of charcoal briquette from sengon wood wastes. Sengon wood waste charcoal was produced with a pyrolysis method at a temperature of > 500 ℃. The charcoal briquettes were produced by mixing charcoal powders with tapioca starch with 5%, 10%, and 15%. The mixed charcoal powders and adhesives were then put into a metal cast and pressed using a Universal Testing Machine (UTM) Testometric M500-50AT under compression of 2,59-5,17 N/mm2 and a target density of 0,5 g/cm3. Biomass briquettes from sengon wood particles were also produced for comparison. The results showed oven-dry density of 0,23-0,25 g/cm3 and 0,18-0,20 g/cm3, for charcoal briquettes and biomass briquettes, respectively. Higher adhesive content increased the density of briquettes. Charcoal briquettes were more hydrophobic than biomass briquettes (control), showing a lower moisture content than control samples. The results of proximate analysis of charcoal briquettes showed volatile matter of 24,96–31,80%; ash content of 3,16–3,24%; and fixed carbon of 58,68–66.40%. Higher adhesive content increased the volatile matter, moisture content, and ash content of the charcoal briquettes and decreased the fixed carbon. The charcoal briquettes have a calorific value of 25,68-27,35 MJ/kg (6.137,67- 6.536,80 cal/g), which is remarkably higher than the control. Higher adhesive content tended to decrease the calorific value of the charcoal briquettes. Lower adhesive content will produce briquettes with good bioenergy characteristics. Sengon wood waste charcoal briquettes with 5% adhesive content have great potential to be developed as an alternative energy source.
