Abstract

The objective of this study was to determine the physical and mechanical properties of oriented strand board (OSB) from three wood species of plantation forests, i.e., Afrika (Maesopsis eminii), mangium (Acacia mangium), and sengon (Paraserianthes falcataria) at various resin contents. OSB was made with a shelling ratio (face:core:back) of 1:2:1 and a target density of 0.6 g/cm3. Methylene diphenyl di-isocyanate (MDI) adhesive was used with 3%, 5%, and 7% resin contents. The physical and mechanical properties were evaluated based on JIS A 5908:2003 standard and the values were compared with CSA 0437.0 (Grade O-1) standard. The results show that the physical and mechanical properties of the OSB were improved as the resin content increased for all wood species. OSB prepared from Afrika and mangium wood strands with 7% resin content showed better physical and mechanical properties than the other OSBs. Thickness swelling of OSB prepared from three wood species had met the CSA O437.0 (Grade O-1) standard. All OSBs produced in this experiment met the standard for MOR parallel and perpendicular to the grain. OSB from three wood species with a 5% and 7% resin content met the standard for MOE perpendicular to the grain. Only mangium OSB with a resin content of 7% met the standards for MOE parallel to the grain. Afrika OSB with 5% and 7% resin content, mangium OSB with 5% resin content, and sengon OSB with 3% and 7% resin content met the standard for the internal bond. Keywords: Acacia mangium, Maesopsis eminii, Methylene diphenyl di-isocyanate, Oriented strand board, Paraserianthes falcataria

Abstract

Agarwood is decayed wood that contains aromatic resins. It is formed biotically by bacterial, fungal, and physical infections due to injuries, such as broken branches, insect and mammal attacks, lightning strikes, and fires. The natural formation of agarwood has encouraged the development of artificially induced agarwood through inducer inoculation. This study aimed to determine the formation of agarwood at the seedling stage, the quality of agarwood produced, and the best inducer to induce agarwood. The research was conducted in March-June 2021 at the Greenhouse of the Faculty of Mathematics and Natural Sciences, Mataram University, Lombok, West Nusa Tenggara. The research method used was a complete randomized design consisting of four inducer treatments such as distilled water (control), liquid inducer, gel inducer, and paste inducer. Each treatment was repeated three times. Twelve experimental units were obtained. Data were analyzed using an analysis of variance, followed by the least significant difference test if the results were significant. The results showed that inoculation of G. versteegii at the seedling level using four inducers could produce agarwood that is classified in kamedangan class. Inoculation using a gel inducer resulted in the highest kamedangan quantity, and the liquid inducer produced the longest transmission of 10.83 cm and the best kamedangan quality. Keywords: agarwood, Gyrinops versteegii, inoculation, Lombok, seedling

Abstract

Changes in the Social Forestry or Perhutanan Sosial (PS) scheme have been made by the Ministry of Environment and Forestry of the Republic of Indonesia, particularly in the state-owned forestry enterprise (Perhutani) working area. A forestry partnership is one of the schemes being developed to replace the previous scheme, Community Forest Management (PHBM). However, increased PS area permits are not always accompanied by increased farmer trust and understanding of the program. This study aimed to determine the institution's effectiveness and institutional condition in the era of PS policy, which is currently a government priority program. One of the community groups granted a management permit is the Forest Village Community Institution (LMDH) Sumber Makmur, located in the Forest Management Unit (KPH) Malang. This study was conducted from December 2020 to March 2021 using a qualitative descriptive method as in-depth interviews and questionnaires with assessment indicators. Respondents were chosen randomly from the entire population using the Slovin formula. The results showed that the institutional effectiveness of LMDH Sumber Makmur still tended to decrease. The confidence level of farmers in the PS program was only around 28.9%, and the level of understanding was 26.7%. The results also showed a low percentage value of farmer participation, external support, the availability of facilities, and gender perspective. Consequently, the government needs to monitor institutions and community groups running PS programs to see institutional developments in each location. Institutional development is essential as an entrance for people to manage forests independently.

Abstract

Bali starling (Leucopsar rothschildi) is categorized as an endangered species based on the International Union for Conservation of Nature and Natural Resources (IUCN) red list. Thus, preventing this species from extinction becomes very crucial. One of the most important activities for this purpose is a soft release method to avoid birds' mortality, which has been done in West Bali National Park (WBNP). However, this method creates the dependency of birds to the artificial treatment and may affect the distribution of Bali starling. Therefore, this study aimed to analyze the population and habitat and create a habitat suitability index model for Bali starling in WBNP. Data were obtained by surveying the Bali starling population, including the number of individuals, distribution, age structure, sex ratio, natality, and mortality. Vegetation analysis was also conducted to determine habitat conditions. Finally, map interpretation data was used to develop a suitable habitat model for Bali starling in WBNP. The results showed that 63 Bali starling were found near the resort office, bird release sites, and binding bird cages. It indicated that the habitat of Bali starling has shifted from the soft release site. The habitat suitability index model of Bali starling in WBNP was Y = 17.145 + 6.640PC1 - 4.055PC2, showing the selected variables only give a moderate determination coefficient (R2 = 40.9%). The artificial treatment created by the WBNP authority seems to be another great factor influencing the existence and distribution of Bali starling in WBNP. It was also indicated that Bali starling could breed in the WBNP, but it tends to have a shifting habitat in the wild.

Abstract

Upstream areas have long been targeted as the priority of water conservation initiatives. While earlier studies often considered underlying socio-psychological factors determining residents' intention and behaviors in water conservation, studies that focused on the resident's intention and behavior in upstream areas, where water is abundant, remain underexplored. The current study used socio-psychological constructs of the theory of planned behavior (TPB), i.e., subjective norm, attitudes toward behavior, and perceived behavioral control, to analyze the determinants of water conservation intention and behavior in two villages upstream of West Java (i.e., Cibeusi and Sanca villages), Indonesia. A total of 200 usable questionnaires were retrieved. Structural equation modeling was used to determine the linkages and strength of relationships among constructs. There was evidence that residents perceived behavioral control exerted the most significant influence on residents' water conservation intention and behavior. Moreover, perceived behavioral control was an effective mediator of the linkage between attitude and residents' intention and behavior. The findings confirmed the suitability of TPB in explaining interrelationships among determinant factors that explain residents' intention and behavior, albeit with different mechanisms and effects. The study implied that increasing awareness of the value of water conservation would significantly affect residents' attitudes, which subsequently increased their willingness to perform water conservation efforts.

Abstract

Damar (Agathis labillardieri) is endemic species to New Guinea, occurring naturally in Papua and West Papua Province, Indonesia. The species is economically valuable due to its resin and wood. This research aimed to study the cones and seeds characteristics of A. labillardieri collected from Sorong Nature Park at Klasaman, Sorong, Papua Barat. The characteristics observed included cone size and weight, number of scales, empty and filled seed, and seed moisture content. The germination test was also performed. Although the stands could produce cones, not all scales contained seeds, and not all seeds were filled seeds. On average, 53 filled seeds per cone or only 50.3 ± 5.7% of the total seeds found as filled seeds. The seed was characterized as a recalcitrant seed with high moisture content and rapid germination. On average, the seed moisture content was 38.9%, with an average germination time of four days. The combined factors that may contribute to the low natural regeneration of A. labillardieri are low filled seeds, seed sensitivity to desiccation, and high mortality in newly emerging seedlings during recruitment. Therefore, facilitating the forest floor for immediate germination of recalcitrant seeds as in A. labillardieri is suggested.

Abstract

Endophytic fungi are the potential biological agent that could stimulate plant growth and inhibit plant disease. The existence of diverse and abundant endophytic fungi encourages continuous exploration. One of the plants that have potential as a source of endophytic fungi is balangeran (Shorea balangeran Korth.). The study aimed to identify the species of endophytic fungi from the leaf and twig of S. balangeran based on morphological characteristics. Fungi isolation was conducted by multiple sterilizations and purification. Furthermore, the macroscopic and microscopic morphological characteristics of the endophytic fungi isolates were also identified. The results showed nine colony characteristics of endophytic fungi. Endophytic fungi of Colletotrichum sp1. (SbD 1.1), Phomopsis sp. (SbD 1.3.1), Colletotrichum sp2. (SbD 1.3.2), and Beauveria sp. (SbD 3.1) were only found on the leaves, while Aspergillus niger (SbB 5.1), Colletotrichum sp3. (SbB 5.2), and Nigrospora sp. (SbB 5.3.2 and SbB 6.3) were only found on the twigs. Endophytic fungi Phyllosticta sp. (SbD 1.2) were found in the leaves and twigs. The growth rate of endophytic fungi showed that Colletotrichum sp3 (SbB 5.2) was the fastest, and Phyllosticta sp. (SbD 1.2) was the slowest among the nine isolates. Endophytic fungi that have been isolated will be analyzed for their benefits as a biological agent in future research. Keywords: endophytic fungi, identification, morphological characterization, Shorea balangeran

Abstract

Climate change and the increasing greenhouse effect are serious problems of global concern today. The existence of forests plays an essential role in carbon sequestration and storage to reduce greenhouse gas (GHG) concentration in the atmosphere. Forest Area with the Special Purpose (KHDTK) of Gunung Bromo has an area of 126,291 ha that is designated as an educational forest. The area has been managed by Universitas Sebelas Maret since 2019 and consists of three main tree species, namely Pinus merkusii, Swietenia mahagoni, and Dalbergia latifolia. This study aims to estimate the potential uptake and economic valuation of carbon stocks in the KHDTK of Gunung Bromo. Stratified Systematic Sampling with Random Start was used as an inventory method in this study. The estimation of above-ground carbon uptake used general allometric equations (non-destructive method). Furthermore, the carbon economy valuation referred to the range of calculating the average carbon price for each program specification. The results showed that the estimated carbon of tree stands in KHDTK of Gunung Bromo reached 75.81 tonnes C/ha with a carbon economic valuation of USD 758.1/ha or equivalent to IDR 10,856,863.80/ha. Exploring the potential for biodiversity (flora and fauna) and environmental services such as carbon sink will support the ecotourism program in KHDTK of Gunung Bromo. Keywords: biomass, carbon estimation, economic valuation, KHDTK of Gunung Bromo

Abstract

Natural preservatives have been widely considered as non-synthetic materials that can prevent the biodegradation of wood due to subterranean termite attacks, namely Coptotermes curvignathus. Melia azedarach is a fast-growing species that has been widely studied for its antifeedant compounds and shows good potential to be developed as a biopesticide, especially as an anti-termite. This study aimed to identify the termicide and antifeedant properties of the wood, leaves, and bark extracts of Melia azedarach against subterranean termites and identify their bioactive compounds. The acetone extract from the three parts of the tree was fractionated. The most active fractions were selected from each part based on the percentage of termite mortality and antifeedant activity and analyzed for its bioactive compounds by pyrolysis GCMS. The ethyl acetate fraction of Melia azedarach bark exhibited strong toxic properties compared to other fractions. In the leaf section, the diethyl ether fraction showed the best termite repellent (antifeedant) properties. The anti-termite properties influenced phenolic compounds and organic acid that dominated the bark ethyl acetate fraction and leaf diethyl ether fraction. These findings show the great potential of bioactive compounds from biomaterials to be developed as a promising biopesticide. Keywords: anti-termite, bioactive compound, Melia azedarach, natural preservative
