Heavy metal contaminants like mercury is a serious problem to human, animals, and some plants’ health. Phytoremediation is an alternative technique, which can remediate the contaminants from soil using a hyperaccumulator plant. The goal of this research was to study anatomical changes of plant main organs (roots, stems, and leaves) of Ipomoea reptans which are assumed as a hyperaccumulator plant that grows in mercury contaminant. The mercury concentration of the growth medium was 0, 61.871, 92.258, and 107.046 ppb. Ipomoea reptans were harvested after 27 days. The anatomical changes of the plant’s main organs were observed by preparing the cross-section of roots, stems, and leaves of I. reptans. The result showed that mercury treatment has caused anatomical damage at the xylem vessel of the root, and decreased bulliform cell size. The anatomical damage was found only in the root of I. reptans. The mercury concentration in media decrease to 0 ppb (P0), 50,420 ppb (P1), 58,583 (P2), and 96,120 (P3).

Mushroom is one of living things with abundant diversity and has various beneficial potentials; one of them is as medicine. The use of mushrooms as medicine has long been known primarily as traditionally made herbs and the knowledge has been passed down for generations. The Pocut Meurah Intan Forest Park as a conservation forest, stores a variety of mushrooms in it. Data about the type of mushroom that has medicinal potential existed in the forest park has never been published so it is important to do so. This study aims to record the types of mushrooms that have benefits as medicines. The method used is an exploratory survey through a trail or tracking path then identified as a medicinal mushroom base on literature studies. The results of the study found 15 species of mushrooms that have potential as medicine, namely Cookeina tricholoma, Sarcoscypha coccinea, Tremella fuciformis, Auricularia auricula-judae, Flammulina velutipes, Schizophyllum commune, Scleroderma citrinum, Boletus edulis, Trametes versicolor, Lentinus tigrinus, Lentinus squarosulus, Ganoderma applanatum, Ganoderma resinaceum, Thelephora ganbajun and Lycoperdon echinatum. This shows that Pocut Meurah Intan Forest Park has great resources and potential that can be utilized for the benefit of the surrounding community, and it needs to be preserved so that diversity is maintained and can be used by future generations.

DNA extraction is the first step in obtaining high-concentration and high-purity DNA that can use in the subsequent steps. Because the leaf structure is challenging and contains several secondary metabolites that can affect DNA extraction results, DNA extraction on dry leaves of Dipterocarpaceae is considered problematic. This research aims to find a suitable method for extracting DNA from the preserved Dipterocarpaceae leaves. Preserved leaves of Dipterocarpaceae in silica gel will dry up, making them tough to destroy. Perform DNA extraction is generally using CTAB buffers or extraction kits. According to the results of this study, extraction with modified CTAB buffer result in DNA with higher concentration and purity values than DNA extracted with the kit. DNA isolated from the modified CTAB can be used as a template in the PCR process to amplify the matK gene.

Jurnal Natural Volume 21 Number 2, June 2021
Publisher : Universitas Syiah Kuala

The Dipterocarpaceae family is one of the identified plant groups with high conservation value that exist in Weh Island Nature Tourism Park. However, the data availability on the species diversity and population structure of Dipterocarpaceae in Weh island in particular and Aceh in general is still very limited. Thus, it is necessary to conduct studies on species diversity and population structure of Dipterocarpaceae from Weh Island. This study aims to obtain data on species abundance and diversity, species composition of each stratum, population structure, and stand structure of Dipterocarpaceae in Weh Island Nature Tourism Park. This research utilized transect method with randomly selected plots according to topographic conditions. We found two Dipterocarpaceae species: Shorea sumatrana (Slooten) Desch and Dipterocarpus hasseltii Blume. Shorea sumatrana (Slooten) Desch has the greatest abundance of all types and strata. The diversity of Dipterocarpaceae species in Weh Island Nature Tourism Park is categorized as low because the diversity index value is in the range of H'1. This means that the presence of seedling and sapling strata from each species has a major effect on the survival of the Dipterocarpaceae family in the future. The stand structure of the Dipterocarpaceae family in normal conditions is indicated by an inverted “J” shaped diagram.
