Abstract

Mangrove forests play an important role in macrozoobenthos ecology, assisting them in foraging, sheltering, and reproduction. In order to better understanding the genetic diversity and population genetic structure of macrozoobenthos, the mitochondrial 16S subunit (16S rRNA) gene was used. Present study aimed to determine genetic diversity and community structure of macrozoobenthos in the North Sumatra and Aceh mangrove forests, Indonesia. The reliaprep gDNA tissue miniprep system kit was used to extract 50 samples. To determine the PCR product's molecular weight, UVITEX software was employed. Genetic polymorphism was examined with GenAlex version 6.502, and each community underwent principal coordinates analysis (PCoA). MVSP 3.2.2 software and the unweighted pair group method with arithmetic mean (UPGMA) were used to construct the dendrogram. The 16S rRNA gene revealed a band size in the range of 370–500 bp. The PCoA showed that approximately all individual macrozoobenthos from each community structure were localized in the same quadrant. Genetic variation was varied by 3% between populations and 97.5% within individuals according to the analysis of molecular variance (AMOVA), with the dendrogram classifying the populations into two major clusters. Dendrogram analysis showed low genetic differentiation between macrozoobenthos populations of North Sumatra and the Aceh mangroves, implying the low ability of individuals in a population to adapt. The high polymorphic information content (PIC) value (0.886) reported was consistent with the number of alleles and size of the population's heterozygosity value. Present findings provide important information that will assist in formulation of mangrove conservation and restoration approaches.

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

Highlight Research The genetic diversity of fish and shrimp from mangrove habitats was relatively substantial, with a heterozygosity of 0.926 and the exception of Langsa samples. AMOVA revealed that the diversity among individuals in the populations were higher compared to those within individuals. DNA barcode in mangroves is useful in developing mangrove conservation and restoration initiatives   Abstract Fish and shrimp are among the species that are vulnerable to high level of disturbance in mangrove ecosystem. This study aimed to investigate the implementation of 16S rRNA gene for fish and shrimp barcoding in mangrove ecosystems in North Sumatra and Aceh, Indonesia. 50 samples fresh fish and shrimp were collected from five mangrove ecosystems in North Sumatra, namely Belawan, Lubuk Kertang, Percut Sei Tuan, and Pulau Sembilan and Langsa of Aceh for DNA extraction process. The research was divided into four activities: sample collection, DNA isolation, PCR amplification, and data analysis. DNA was extracted using kit extraction (kit Reliaprep gDNA Tissue Miniprep System) and with PCR amplification. Genetic parameters were analyzed using Gen Alex 6.51 software and the relationship between sites was examined using the MVSP 3.22. The genetic diversity of fish and shrimp from mangrove habitats was relatively substantial, according to the findings, with a heterozygosity of 0.926, with the exception of Langsa samples, which were only identified in subclass A1. Genetic relationship between sites revealed that all samples clustered into two branches and were randomly dispersed within each site. This work confirmed the 16S rRNA gene worked for fish and shrimp barcoding in mangrove ecosystems, North Sumatra and Aceh, Indonesia and our findings are expected to be useful in developing mangrove conservation and restoration initiatives.

Abstract

The extraction method plays a crucial role in obtaining high-quality DNA samples, which is indispensable for various molecular biology techniques and analyses, enabling a deeper comprehension of genetic information and biological processes. The objectives of the study were: a) to optimize the chloroplast DNA extraction protocol by comparing modified CTAB methods and GeneAid for both leaf and wood samples of Shorea leprosula, a major commercial timber species, and b) to identify a suitable cpDNA region that exhibits variability and universality across taxa. Total DNA was analyzed by gel electrophoresis followed by Sanger sequencing to determine the amplification success. The results revealed that trnL intron, trnL-trnF, and trnG yielded readable sequences of the expected length (maximum 586 bp, 480 bp, and 908 bp, respectively), while the rps 16 intron failed to assemble a contig. The petL-psbE region provided long readability for reverse sequences (769 bp) but not for the forward sequence (195 bp). Higher successful DNA extraction was achieved from the leaves compared to the woods. The lower sequencing quality may be attributed to suboptimal primer design, the structural features of the regions resulting from extensive repetitive sequences, and the suboptimal condition of the extraction method in eliminating wood chemical compounds.

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

Selective Cutting and Line Planting (TPTJ) silvicultural systems and Indonesian Selective Cutting and Planting (TPTI) are two of the five silvicultural systems that have been determined by the Ministry of Forestry Regulation No. P.11 / Menhut-II / 2009 juncto P.65 / Menhut-II / 2014 concerning silvicultural systems in the area of timber forest product utilization permits (IUPHHK) in production forests. Three other silvicultural systems based on the regulation are the Gap Logging silviculture system, the Fully Made Rejuvenation System, and the Multi Silviculture System. This study aims to examine the implementation of the TPTJ and TPTI systems in the PT Intracawood Manufacturing (PT Intraca) area, Bulungan Regency, North Kalimantan. The methodology of this research is through the approach of growth analysis, comparison of stand increment, observation of environmental conditions, interviews and literature study. Based on the field research, it was found that the diameter increments of Shorea leprosula, Shorea dasyphila, and Shorea parvifolia were greater in the TPTJ system compared to TPTI. However, the TPTI silviculture system at PT Intraca is easier to apply in the field than the TPTJ silviculture system. The TPTJ system has become less effective because planting in the TPTJ system has been carried out by making a 3-meter wide track with a length of approximately 1 km in a plot and if there is potential for the wood to become ineffective. In the area of PT Intraca, to improve the effectiveness of the TPTJ system a mosaic system is used where the planting path is made only in areas with less potential and representative for planting. The types of plants planted in the TPTJ system are far superior, perspective, and are faster than the types of plants in the TPTI system. Planting/enrichment in the TPTI system is easier because it does not need to make a planting path. Planting with seedlings from the extraction is only a transfer from the growth of tillers from areas with an excessive potential for tillers.

Abstract

Mindi (Melia azedarach) is a fast-growing woody plant with potential for community forest development. Mindi wood is used to furniture material, parquet, fancy plywood, and fancy laminated veneer, and it is also exported. Although the community forest in Deli Serdang Regency is established as a seed source for mindi in North Sumatra, information on its diversity is still lacking. The aim of this research was to get information about morphological differentiation of mindi in Deli Serdang Regency. Direct observation and measurement on morphological and growth character of mindi had been conducted in three populations of community forest in Deli Serdang Regency. Those were Percut Sei Tuan population, Biru-Biru population, and Pancur Batu population. The result showed that of 19 observed morphological characters, there were two characters: number of leave and fruit weight able to differentiate the populations—individual tree from three population clustering into three groups. The first cluster consists of 35 individual trees from Percut Sei Tuan (7 trees), Biru-Biru (12 trees), and Pancur Batu (16 trees). The second cluster consist of 24 trees originated from Percut Sei Tuan (13 trees), Biru-Biru (8 trees), and Pancur Batu (3 trees). A third cluster consists of one tree from Pancur Batu.
