Abstract

Mangrove forests are important in climate mitigation, particularly for their greatest carbon storage. Rhizophora apiculata, a mangrove species with numerous advantages, is frequently employed in restoration activities. Monoscpecies restoration activities are well known, although information on floristic composition and carbon uptake must be available. The objective of this research was to investigate the floristic composition and carbon stock of R. apiculata in the Pasar Rawa Village restoration area, Langkat Regency, North Sumatra Province. This study employed the vegetation analysis approach and carbon estimates based on diameter breast height (DBH) and total vegetation height. The study's findings indicate low floristic diversity in the research area. At the seedling stages, the greatest IVI (113.68%) was discovered in Achanthus ilicifolius, and the only species found in the sapling stage with an IVI value of 200% was R. apiculata. The study of diversity indices revealed very low values at the seedling stage (H'= 0.806) and no diversity at the sapling stage. The total carbon stored estimation in R. apiculata stands relatively low, at 8.56 tonnes/ha. The absorbed carbon produced by R. apiculata is 31.42 tons/ha with a CO2 absorption of 3.141 g/m2 and is classified as relatively low

Abstract

The Universitas Sumatera Utara has various types of trees scattered in the surrounding environment. Swietenia macrophylla, Mimusops elengi and Polyalthia longifolia are the three most common tree species found on campus. To maximize the potential for utilizing tree species on the Universitas Sumatera Utara campus, several efforts can be made, one of which is by exploring the presence of cellulolytic fungi. Cellulolytic fungi are fungi that are able to hydrolyze cellulose which can produce cellulase enzymes. This study aims to obtain the potential and identify cellulolytic fungi from the soil under Swietenia macrophylla, Mimusops elengi and Polyalthia longifolia stands. Sampling was taken by making 3 plots on each type of stand measuring 20 m x 20 m with a soil depth of 0 – 20 cm. In each plot, 5 sampling points were made. The soil taken from each type is then composed. Isolation of cellulolytic fungi was carried out using Carboxy Methyl Cellulose (CMC) media. The potenstial of cellulolytic fungi is obtain by calculating the cellulolytic index. All isolates obtained were identified morphologically down to the genus level. The result showed that the potency of the cellulolytic fungi ranged from 0.05 to 1.36. The identification results that the isolates included the genus Aspergillus and Trichoderma.

Abstract

The arboretum of the Universitas Sumatera Utara (USU) is an area for collecting and conserving tree species in North Sumatra. One of dominant family found in USU Arboretum is Moraceae.  The objective of this reserach was to determine Moraceae diversity in the USU Arboretum. The census approach of vegetation analysis was used to determine the identity and abundance of Moracea. The research found 9 (nine) Moraceae species belongs to two genera in the USU arboretum, those were Ficus microcarpa, Ficus elastic, Artocarpus heterophyllus, Ficus padana, Ficus fistulosa, Artocarpus altilis, Ficus benjamina, Ficus ampelas and Ficus hispida. The species with the highest density value (57.92%) is Ficus hispida. The diversity index, richness index, and species dominance index were all quite low in the research location, with values of 1.455, 1.226, and 0.370, respectively. Meanwhile, the species evenness index at the research location is 0.662, which is classified into moderate. To improve the diversity of Moraceae in the USU arboretum, species enrichment activities are needed.

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

Pante Bayam is one of natural mangrove area in Aceh Province. Due toanthropogenic activities such as fishpond, the area become degradated. This studyaims to analyze soil organic carbon (SOC) stock based on soil depth and texturecharacteristics at several observation points in the study area. Data were collectedfrom seven sample locations with four categories of soil depth: 0–15 cm, 15–30cm, 30–50 cm, and 50–100 cm. The results showed that the highest carbon stockwas found at a depth of 50–100 cm, reaching 159.1 Mg C/ha, while the 15–30 cmlayer had the lowest carbon stock. This indicates that the subsoil plays a significantrole in long-term carbon storage. The distribution of carbon stocks also variedbetween locations, where PB04 and PB07 showed the highest values, while PB05and PB06 showed the lowest. Correlation analysis showed a positive relationshipbetween clay content and soil carbon stock, indicating that fine soil texturesupports carbon accumulation through the formation of stable aggregates. Thesefindings emphasize the importance of soil management that considers soil depthand physical characteristics to increase the potential for climate change mitigationthrough sustainable soil carbon storage
