Abstract

The selection of tree species suitable for restoration in diverse site conditions is still a challenge. Therefore, this study aimed to analyze the phenotypic and genetic characteristics of Dryobalanops aromatica seedlings growing in mineral soil media and peat media. Phenotypic characteristics were evaluated by analyzing the growth performance, leaf morphological characteristics, leaf color, and chlorophyll content, while genetic characteristics were evaluated by using microsatellite markers. The study revealed that seedlings planted in peat media exhibited greater height and shoot length growth, although the difference was not statistically significant compared to those in mineral soil media. However, seedlings in mineral soil media displayed a significantly higher survival rate than those in peat media. Peat-grown seedlings had higher chlorophyll content in their leaves, while mineral soil-grown seedlings displayed a lighter green leaf color based on digital analysis. Genetic analysis indicated a high genetic diversity of overall D. aromatica seedlings (He = 0.635) and unclear genetic structure between the two media. Overall, these findings demonstrate the successful adaptation of D. aromatica seedlings to peat media, positioning them as a promising choice for peatland restoration.

Abstract

Gunung Walat University Forest (GWUF) in Sukabumi Regency, Indonesia, plays a crucial role in providing various ecosystem services. Five important Shorea trees, i.e., S. stenoptera, S. mecisopteryx, S. pinanga, S. palembanica, and Shorea leprosula have been planted in GWUF as an effort for its conservation and object of research. An evaluation of the adaptability and suitability of these species to the GWUF ecosystem, as well as their wood characteristics, needs to be carried out regularly. Therefore, the study aimed to examine the growth performances and physical wood properties of five Shorea species, i.e., Shorea stenoptera, S. mecisopteryx, S. pinanga, S. palembanica, and S. leprosula at the age of 15-year-old planted in GWUF. The results indicated that S. leprosula exhibited the best growth performance in terms of average diameter (19.64 cm), volume (0.27 m3), slenderness (126.58), and wood density (0.94 g/cm3), and S. stenoptera showed the best performance in average height (23.35 m). While the poor performance was shown by S. palembanica in terms of average diameter (6.73 cm), height (11.15 m), volume (0.02 m3), wood density (0.87 g/cm3), and specific gravity (0.45), and S. stenoptera in terms of average slenderness (202.73). In addition, significant differences in tree height, diameter, volume, wood density, specific gravity, and moisture content were found in S. palembanica compared with other species. The relationship between the growth and physical wood properties parameters varied between species. The study revealed that planting the five Shorea species in GWUF is suitable for increasing vegetation cover and conserving the species.

Abstract

Universities play a key role in driving positive change by equipping students to address environmental and social challenges. This study examines how students at IPB University perceive various sustainability initiatives implemented on campus. Based on a survey of 1,545 undergraduate students, the research explores their knowledge, awareness, and interest in these efforts. The results show that while most students are familiar with the general concept (87.6%), fewer have knowledge of specific programs, institutional rankings, or the university’s Campus Sustainability Office. Nevertheless, nearly all respondents consider these efforts important (98.7%) and support active student involvement (97.2%). Many also express a desire to see these topics integrated into academic courses (84.9%).These findings highlight the need for improved internal communication and curriculum development to enhance student participation. The study offers both practical and academic insights for improving sustainability strategies in higher education institutions. Future research should include multiple universities and consider mixed-method approaches to better understand the factors influencing student engagement

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

Macassar ebony (Diospyros celebica Bakh.) is an endemic tree species native to Sulawesi. To date, there are limited comprehensive publications regarding its genome assembly. In this study, we employed paired-end libraries of HiSeq 4000 Illumina, generating 141.2 million paired-end reads (42.4 Gigabases). Our analysis revealed the presence of 950,081 Scaffolds, with an N50 value of 6,023. Notably, BUSCO analysis identified 183 (12.7%) complete and single-copy BUSCOs (S), as well as 9 (0.6%) complete and duplicated BUSCOs (D). Furthermore, we identified 12,890 microsatellites within the Macassar Ebony genome. These microsatellites encompass 14 dinucleotide SSR motifs, 12,090 trinucleotide SSRs, 780 tetranucleotide SSR motifs, and 6 pentanucleotide SSRs. This dataset represents a valuable resource for assessing Macassar Ebony genetic makeup in its natural habitats and for subsequent analyses of the Macassar Ebony genome.

Abstract

Agarwood is a distinctive wood resin product extracted from the important genus of Aquilaria, but the population of agarwood-producing trees from natural forests in Indonesia is threatened due to over-exploitation, leading to an urgent call for conservation and sustainable uses. Molecular techniques such as DNA profiling have been used to ensure the legality, conservation, and sustainability of species from this genus. In this study, cross-species amplification of microsatellite markers initially developed for Aquilaria crassna was developed on two other closely related agarwood species (Aquilaria malaccensis and A. microcarpa), and their genetic variation was evaluated. The four loci (6pa18, 10pa17, 16pa17, and 71pa17) were used to amplify leaf genomic DNA from 55 trees across three Aquilaria species. The results showed that the four loci could successfully be amplified in A. malaccensis, A. microcarpa, and A. crassna. In addition, A. crassna exhibited higher genetic variation (Na=2.75, Ne=2.35, He= 0.5672, and F=-0.727) than A. malaccensis (Na=2.75, Ne=2.19, He=0.5424, and F=-0.598) and A. microcarpa (Na=2.50, Ne=2.11, He= 0.5234, and F=-0.734) indicated the transferability of microsatellite markers in closely related agarwood species, possibly due to the flanking region in these four microsatellite regions being well-conserved in several agarwood species. These findings indicated that the markers tested here can be considered an effective tool for future studies in population and conservation genetics to support the management of agarwood genetic resources and track its supply chain to prevent overexploitation.

Abstract

Dipterocarpaceae are economically important, contributing over 85% of Indonesia's timber exports. However, this crucial resource is increasingly threatened by illegal logging, habitat destruction, and the illegal timber trade, which jeopardize dipterocarp population. Furthermore, conservation efforts utilizing genetic and forensic techniques often encounter substantial challenges due to the complexities in DNA extraction protocol. To address this, the study aimed to enhance the efficiency of DNA extraction methodologies by comparing two methods: the modified cetyltrimethylammonium bromide (CTAB) and the Genomic DNA Mini Kit (Plant) from Geneaid Biotech Ltd. The research focused on leaf and wood samples from two species, spesifically Rubroshorea leprosula (Miq.) P.S.Ashton & J.Heck and Shorea laevis Ridl. For each of these species, five leaf and five wood samples were extracted using both methods. The quality of the DNA extraction was evaluated using electrophoresis and quantified with a Qubit fluorometer. Higher DNA concentrations were obtained with the modified CTAB method compared to the GeneAid kit for both R. leprosula and S. laevis, particularly in leaf tissue. The GeneAid kit consistently exhibited low DNA yield efficiency compared to the modified CTAB method for both species. Additionally, PCR amplification of both leaf and wood samples confirmed that the extracted DNA was suitable formolecular analyses. These findings not only contributed to laboratory applications but also served as practical tools for species identification and genetic conservation for sustainable forest management and law enforcement.

Abstract

Sumedang Regency has a hilly landscape, making it one of the 13 cities/regencies in West Java Province that are prone to landslides. A total of 80 landslide incidents were recorded from 2019 to 2023. These landslides resulted in 45 fatalities, 53 injuries, and damage to 317 infrastructure units. This situation indicates the importance of conducting an analysis of landslide hazard distribution. The landslide hazard distribution analysis is carried out using a weighting and scoring method on the parameters used, which include: slope gradient, rainfall, actual land cover, landform, lithology, and soil type. Based on these parameters, four landslide hazard classes were identified in Sumedang Regency: low, medium, high, and very high hazard classes. Proportions of these hazard are as follows: high hazard class (42.24%), medium hazard class (40.38%), low hazard class (13.90%), and very high hazard class (3.49%). The low hazard class is mainly found in the northern part of Sumedang Regency, the medium hazard class is widespread in sloping areas, and the high to very high hazard classes are primarily found in the Tampomas mountains and areas with hilly landforms. Slope gradient and rainfall are the factors that most influence landslide hazards, making it necessary to design appropriate mitigation.
