Abstract

The joint of glued laminated wood with adhesive is widely used and affects the static bending strength value in its use. The compression pressure is one of the critical factors in the gluing of joints. This research aims to determine the effect of variations in compression pressure on the static bending strength of finger-jointed red meranti (Shorea sp.) wood glued with an exterior type of polyvinyl acetate (PVAc) adhesive in Synteco brand. The static bending strength testing referred to the German standard DIN (Deutsches Intitut fur Normung) DIN 52186-78. The data from 3 treatments of compressive pressure variations (2 bar, 2.5 bar, and 3 bar) were analyzed for variation in a completely randomized design (CRD) with 20 replications. The research results showed that the highest static bending strength of finger-jointed Shorea sp. was found at a compression pressure of 3 bar (P3), in which its modulus of elasticity (MoE) was 9,975.53 N/mm2 and the modulus of rupture (MoR) was 60.77 N/mm2. The MoE and MoR of the finger-jointed wood were still lower than its control (without joints), in which MoE was 10,017.07 N/mm2 and MoR was 82.07 N/mm2.

Abstract

Lamination technology is an effort to overcome various problems resulting from the wood industry experiencing difficulties in finding raw materials to support its operations. Developing environmentally friendly materials such as laminate products is also becoming a concern in the construction sector. This research will use fast-growing wood species with bamboo, namely rajumas wood, sengon wood, and petung bamboo. Several factors, including the type of wood, type of adhesive, adhesive melt weight, and compression pressure, influence the manufacture of laminated boards. This research aims to see the effect of the type of wood combination (sengon and rajumas) with petung bamboo and the effect of pressure and their interactions on their physical and mechanical properties. The experimental design was a factorial design with 2 factors (compression pressure and combination type) with four treatments and three replications. Based on the results of testing laminated boards' physical and mechanical properties, several conclusions can be drawn, such as density testing, which shows that the type of wood combination has a significant effect. At the same time, compression pressure and its interactions have no significant effect. Moisture content testing showed that pressure had a significant effect, while the type of wood combination and its interactions had no significant effect. The thickness expansion test shows that the type of wood combination and its interactions have a significant effect, while the compression pressure has no significant effect. Thickness shrinkage testing shows that the type of wood combination, compression pressure, and their interactions do not significantly affect it. Modulus of Elasticity (MoE) testing shows that the type of wood combination, compression pressure, and their interactions do not significantly affect it. Modulus of Rupture (MoR) shows that the type of combination has a significant effect, while the compression pressure and its interaction have no significant effect.

Abstract

Rajumas wood is a type of fast-growing wood that is included in durable class IV-V. The availability of local wood is abundant and is commonly used in West Nusa Tenggara (NTB) Province. This wood has a low durability class, so it needs special treatment, namely pickling. This research aims to determine the level of absorption, retention, and penetration of rajumas wood. The samples used were the core and sapwood of Rajumas wood. This research uses a cold soaking method with 1% biocide preservative with a soaking time of 12 hours, 24 hours, and 36 hours. The results showed that the TC sample (core part; soaking time 36 hours) produced the highest absorption and penetration values, 0.2035 g/cm3 and 0.3575 cm, respectively. Meanwhile, the GC sample produced the highest retention value (sapwood; soaking time 36 hours), namely 0.0090 g/cm3. These results show that the durability of rajumas wood in the heart and sapwood is relatively high at the absorption level, while the retention level tends to be low.

Abstract

Knowledge is essential for people to adapt to nature and becomes a cultural heritage in managing existing natural resources with knowledge, customary, and cultural norms in the community's concept of thinking. Forest honey from Ensabang Village, Sepauk District, Sintang Regency, is honey produced by Apis dorsata bees, which is managed by the community using the Tikung technique, the management of which is based on the community's local knowledge and customary rules. This research aims to examine forms of local knowledge in the management of Tikung honey. This research used interview techniques with all Tikung honey farmers, and the data was analyzed using qualitative descriptive analysis. The study results show that the management of Tikung honey is carried out individually. The Tikung is placed on the river bank and the ground, and the types of wood used to make Tikung are Tembesuk (Fagraea fragrans) and Kawi (Shorea balangeran). Harvesting forest honey is carried out at night, and packaging and marketing are carried out directly by honey farmers. The traditional rule is that people are prohibited from burning near nest trees, destroying and cutting down nest trees and food trees, and putting Tikung in other people's trees and gardens. There are written sanctions and fines for those who steal and claim other people's Tikung.

Abstract

Community Forestry (HKm) is a scheme that aims to empower local communities and provide access to manage protected/production forest areas. The pine resin commodity is one of the sources of livelihood for the community in the Cempalagie HKm area by utilizing existing access. Value chain analysis is very important to find out the pine resin commodity business actors in the marketing chain from upstream to downstream, namely from raw materials to become a product through qualitative methods with a descriptive approach. The results of the value chain analysis will then show the market structure in the form of market type, number of sellers and buyers, product differentiation, entry barriers, cost structure and conglomeration formed in each chain. The number of respondents was selected as 30 households by census based on respondents who work as pine resin tappers. The results showed that pine resin commodity business actors consisted of tappers, intermediary traders and wholesalers or pine resin processing industries in which the flow of goods, information and money occurred and marketed pine resin and pine resin products in the form of gondorukem, turpentine, alpha pinene and delta carene to international markets, namely India, Vietnam and China.

Abstract

Bogor Botanical Garden (BBG) is an ex-situ plant conservation area intended for conservation, research, education, tourism, and environmental services. As a tourist destination, BBG attracts many people every day. Human activities and unfavourable environmental conditions have caused damage to the existing collection. In 2021, 2022, and 2023, tree health monitoring was carried out using the Forest Health Monitoring method and repeated in 2024 by this research to assist the BBG management in ensuring the tree collections remain healthy and sustainable and provide a safe and comfortable environment for visitors. Seven clusters based on tree family dominance have been made for tree health monitoring. The monitoring includes the location, type, and severity of damage to individual trees in clusters 2, 3, 5, and 6. Some new damage types are found in the clusters. However, Damage Index values (DIV) in 2024 at clusters 2, 3, and 6 are categorized as healthy and DIV cluster 5 has changed to the light damage category. We observed that damages that have occurred are interdependent, where one damage can cause another damage. These findings suggest the importance of the BBG managers to provide immediate action on damaged trees to maintain the collections.

Abstract

Jabon (Anthocephalus cadamba Miq.) is a fast-growing wood that is widely utilized by the society as a construction material and furniture making. This study aimed to increase the density of jabon wood through a vacuum pressure impregnation method. Furfuryl alcohol (FA) and nano-SiO2 with three concentrations (0.5%, 0.75%, dan 1%) were used as impregnation additives, with control and FA without nanoparticles as comparisons. Impregnation was initiated with a vacuum (0.5 bar) for an hour, followed by pressure (2.5 bar) for 2 hours. The significant results on the physical properties of jabon wood including weight percent gain (WPG), bulking effect (BE), and density showed the success of the modification treatment through the FA and nano-SiO2 impregnation process with various concentrations, which the wood density increased from 0.60 g/cm3 to 0.94 g/cm3. The composition of FA and 1% nano-SiO2 solution was the best treatment to obtain the highest density in modified jabon wood.

Abstract

Fast-growing species are chemically and thermally modified to improve quality. These changes affect wood’s chemical composition and surface characteristics. This study aims to analyze the durability of fast-growing teak wood that has been chemically and thermally modified. Chemical modification was carried out by impregnation using citric acid and polyethylene glycol (PEG) 400, while heat modification carried out at 150 °C. The wettability of wood was tested by measuring the contact angle with six types of liquid, aquades, toluene, glycerin, methanol, alkyd, and acrylic paint. The results showed that chemical modification treatment significantly improved the wettability of wood compared to control and heat treatment. Wood treated with citric acid and PEG 400 exhibits a lower contact angle, indicating increased liquid absorbency. Conversely, heat treatment increased the contact angle value making the wood more hydrophobic. Alkyd showed better wettability than acrylic paints, possibly due to their lower viscosity values. This suggests that chemical modification more effectively improves wood coating adhesion.

Abstract

The Lekopancing River, located in Maros Regency, is a crucial source of clean water supply for the people of Makassar City and the surrounding wereas. This study aims to analyze the diversity and role of insects as bioindicators of water quality based on aquatic insect families. The study was conducted in the upstream, middle, and downstream parts of the Lekopancing River, using handpicking and kick sampling for data collection. The collected aquatic insect samples were then identified and analyzed using the diversity index Shannon-Wienner (H') and Hilsenhoff Family Biotic Index (HFBI) methods, which were widely accepted in ecological research for assessing biodiversity and water quality. The number of aquatic insects found was 614 individuals, consisting of 13 species, 13 families, and 7 orders. The diversity index of aerial insects in the upstream and middle parts of the Lekopancing River was 1.26 and 1.72, while in the downstream part, it was 0.42. The HFBI value of 3.26 in the upstream section is still very good; in the middle section, the HFBI value of 4.84 is considered good; in the downstream section, the HFBI value of 7.00 indicates poor quality.
