Abstract

The death of the Rafflesia tuan-mudae buds can be caused by the environmental conditions of the growing place and the host R. tuan-mudae. The purpose of this study is to describe the habitat conditions of R. tuan-mudae and found the cause of the death of Bud R. tuan-mudae. The study used a survey method with data collection techniques in the form of a double plot that is placed purposively where R. tuan-mudae is found with a size of 20 m × 20 m. Based on the result of the study R. tuan mudae was found in 3 observation plots, the first is found in Bukit Salapar, and the other plot is in Gunung Bawang Raya. The results of measurements of the environmental conditions of the R. tuan-mudae habitat show that R. tuan-mudae is often found in conditions of air humidity 87.4 – 91 %, air temperature 25.7 – 26.7℃, soil pH 4.1 – 4.2, soil moisture 69 – 70 %, soil temperature 25 – 26℃, light intensity 542 – 1782 lux, land slope 52.8 – 64.0% and altitude 292-537 MASL. The condition of R. tuan-mudae population has a percentage of 32% live buds, 60% of dead buds and 8% die after blooming. The death of R. tuan-mudae buds is caused by high air humidity 91%, host death, a very steep land slope 64.0% and buried by litter.

Abstract

Vibriosis caused by Vibrio, such as V. parahaemolyticus, is one of several issues in shrimp farming. Antibiotic misuse in disease controlling is suspected of producing environmental contamination resistance of micorbia, and rejecting the products. One of the efforts that can be made to overcome vibriosis by utilizing endophytic fungi in mangroves. This is due to the similarity of bioactive compounds produced by mangroves and endophytic microorganisms. The aim of this research was to analyze at the bioprospection of endophytic fungi as anti-V. parahaemolyticus at the Lampung Mangrove Center (LMC). The aim of this study was to analyze at the bioprospection of endophytic fungi as anti-V. parahaemolyticus at the Lampung Mangrove Center. The method used in the study was exploratory by isolating endophytic fungi from the roots and leaves of mangrove plants that predominantly grow in LMC for further biaoctivity screening process against V. parahaemolyticus. This study employs an exploratory approach with descriptive analysis. Based on the antibacterial activity test using the agar plug method, 9 out of 76 fungal isolates showed the ability to inhibit the growth of V. parahaemolyticus, namely isolates coded L-A1-MD1, L-A1-MD2, L-A1-MD3, L-A2-MA4, L-A2-MA5, L-A2-MA6, L-B1-MD18, L-P4-MA47, and L-A6-MA79. All isolates of endophytic fungi that had bactericidal activity against V. parahameolyticus predominantly come from the mangrove plant Avicena marina.

Abstract

particleboard production, offering an eco-friendly alternative to conventionalwood-based composites. This mini-review synthesizes recent research on thechemical, physical, mechanical, and durability properties of particleboards madefrom sorghum residues, including bagasse, stalks, and leaves. Quantitativefindings show that sorghum particleboards can achieve densities ranging from0.56 to 1.25 g/cm³, modulus of rupture (MOR) up to 34.1 MPa, modulus ofelasticity (MOE) up to 5270 MPa, and internal bond (IB) strength up to 1.92 MPa,meeting the JIS A5908:2003 Type 8 standard in several cases. Moisture content(MC) and thickness swelling (TS) can be optimized to meet dimensional stabilityrequirements through pre-treatment, adhesive formulation, and pressingconditions. Chemically, sorghum biomass has moderate to high cellulose (30–46%) and hemicellulose (21–34%) contents, with lower lignin and ash levels thantypical wood, favoring bonding and composite integrity. Synthetic adhesives (UF,PF, pMDI) and natural alternatives (citric acid, maleic acid, sucrose) have beenexplored, with several formulations showing improved water resistance andbiodegradation resistance. Enhanced durability, including termite and fungalresistance, has been observed, particularly in bio-based adhesive boards.However, challenges remain in scaling production and standardizing raw materialquality. Future research should prioritize optimizing production methods andimproving sorghum-based particleboards' mechanical and durability properties,enabling their use in a wider range of applications.

Abstract

Corruption and forest disturbances represent substantial barriers to sustainabledevelopment in Malaysia's forestry sector. Working within this sector faces avariety of threats. This study explores key corruption risks within the forestrysector, analysing the motives and opportunities that drive forest offences inPeninsular Malaysia. Respondents from relevant agencies were primarilysurveyed using questionnaires. Data analysis using SPSS revealed the corruptionrisks encountered within the forestry sector. Respondents identified fieldwork andreporting as potential areas susceptible to corruption, with their perceptionsanalyzed through central tendency and dispersion measures. Additionally,correlation analysis was conducted to determine the strength and direction of therelationship between motive and opportunity regarding forest offences, and toassess whether the correlation was statistically significant. The findingsdemonstrated a robust positive correlation (r = 0.66) between motive andopportunity, indicating a significant relationship. This suggests that motives forforest offences correspond to opportunities for such offences. This studyhighlights the need for targeted collaboration between the Forestry Departmentand relevant authorities to develop specialized training programs. These programsare crucial for effectively investigating and prosecuting forest violations,ultimately reducing corruption risks

Abstract

friendly material. Two local Indonesian bamboo species, namely apus bamboo(Gigantochloa apus) and ater bamboo (Gigantochloa atter), have been widelyused in various fields but still face challenges such as fading color and lowresistance to moisture. This study aims to investigate the color changes in apusbamboo and ater bamboo after undergoing heat treatment using oil at varyingtemperatures of 160°C, 180°C, 200°C, and 220°C. Five-year-old bamboo sampleswere cut into cylindrical shapes with a diameter of 10 cm and a height of 5 cm,then tested for color before and after the heat treatment. The treatment was carriedout for 2 hours using oil as a medium, then dried in an oven. Color changes wereanalyzed using a general colorimeter scanner. Data collection on communitypreferences for bamboo colors was conducted by distributing questionnaires. Thered-green chromaticity changes in apus bamboo exhibit a decreasing trend,whereas ater bamboo shows an increasing trend. The yellow-blue chromaticitychanges in both bamboo species show an increasing trend. For the lightness level,both bamboos have decreased. The overall color change in apus bamboo and aterbamboo increases with the increasing temperature. The color preference resultsrevealed that women prefer bright colors in both bamboo species. Men are moreselective in their color preferences; some choose bright colors, but many alsochoose dark colors.

Abstract

Mangrove ecosystems are important in ecological, economic, and social aspects,especially for coastal communities. However, damage to mangrove ecosystemsdue to land-use changes for purposes such as settlements and fish ponds canthreaten their sustainability. This study aims to analyze the potential of themangrove ecosystem, apply the kao-kao model in silvofishery pond management,and analyze the potential of mangroves in increasing the income of the communityin Pematang Kuala Village, Teluk Mengkudu Sub-district, Serdang BedagaiDistrict, North Sumatra Province. The methods used include field surveys forvegetation analysis and interviews with Kelompok Usaha Bersama (KUB)Nelayan Sepakat members. Vegetation analysis was conducted in three zones:utilization zone I, II, and the protection zone. Each zone consisted of 5 plots,totaling 15 plots. Interviews were conducted with 27 respondents. The studyresults showed that the mangrove ecosystem in Pematang Kuala Village isdominated by Avicennia marina and Rhizophora mangle, with an important valueindex of 300 in both utilization and protection zones. In the protection zone, theShannon-Wiener diversity index was 0.95, indicating a low level of diversity.Based on the kao-kao system model, it was observed that the productivity of fishponds and fishermen's catch increased. Community income has significantlyincreased over the last five years, with an average net income of IDR 19,550,000every six months. The presence of mangroves also provides indirect benefits as acoastal protector from abrasion, with an estimated economic value of IDR247,950,000 per year.

Abstract

Macadamia integrifolia, locally known as Macadamia, is a tree species native toQueensland, Australia. The species is also recognized as an appropriate option forland rehabilitation in Indonesia, with one location being the Lake Toba catchmentarea in North Sumatra. This species is planted on a large scale because of itsadaptability and relatively short harvesting time. The high demand for macadamiaseeds cannot be supported by the species' ability to regenerate, as naturalregeneration is slow due to the thick and hard seed coat. As a result, a short-term,quality propagation technique that the community can easily use, such as shootcuttings, is required. This study aimed to determine the success of the shoot cuttingtechnique and the adventitious roots development on macadamia cuttings. Thecutting material was obtained from a healthy mother tree from the Sipiso-pisogarden, North Sumatra. The research was designed by using the factorial completeblock design with two factors randomized design with two factors namely cuttingmedia (A) and auxin application (B). The media treatment consisted of sand andtopsoil mixture (A1: 1/1 v/v), pure sand (A2), and pure topsoil (A3), while theauxin application consisted of 0 g (B1), 200 ppm (B2), and 600 ppm (B3). Alltreatments were carried out with 3 replications, each consisting of 5 individualcuttings. The results showed that macadamia shoot cuttings varied survival rateranging from 33.33 % to 86.66% with the rooting percentage ranging from 6.66%-40%. The highest survival rate was found in the top soil mixture: sand and withoutauxin treatment (88.66%) while the lowest was found in sand and without auxin(33.33 %). The cutting media and auxin application did not significantly affect allthe observed parameters. Based on histological root observations, the adventitiousroots of Macadamia form from the wound-induced root with a process that beginswith callus formation and ends with the advent of adventitious roots. This researchfound that the juvenile level of the cutting material used is considered a veryimportant factor in the success of macadamia shoot cuttings.

Abstract

Wan Abdul Rachman Grand Forest Park (Tahura WAR) is a conservation forestarea that serves as a source of water resources that the community utilizes daily.This research analyzes the characteristics influencing people's willingness to payfor water environmental services in the Tahura WAR. This research wasconducted from October to November 2024. The research location is based onboth villages, where water users are from the Tahura WAR area. Based on thisresearch, the results obtained show that the characteristics of respondents' age,occupation, income, water source, and the amount of water demand/day positivelyinfluence the willingness to pay of the community. The variable that has asignificant influence is income. In contrast, the variables of age, occupation, watersource, and the number of water needs/day do not significantly influence the valueof the willingness of the community of water environmental service users in WanAbdul Rachman Forest Park. This research is expected to make a scientificcontribution to developing studies on environmental economics, especially in thecontext of willingness to pay for water environmental services. The results of thisstudy are expected to be a reference for future researchers who are examiningsocial, economic, and environmental factors
