Aktivitas Antibakteri Fraksi Diklorometan dan N-Heksana Paku Sisik Naga (Drymoglossum piloselloides (L) Presl.) Terhadap Bakteri Staphylococcus aureus dan Salmonella typhi
Get PDFThe potential use of dragon scales have been used by people in Kalimantan as anti-inflammatory drugs, oral thrush and toothache. Dragon scales (D. Piloselloides) is one of epiphytic plants in association with other plants. This study aims to determine the antibacterial activity of the dichloromethane and n-hexane fraction of dragon scales against S. aureus and S. typhi. The research was conducted from October to December 2015 in the Pharmaceutical Chemistry Laboratory Faculty of Medicine, Wood Technology Laboratory Faculty of Forestry, Chemistry Laboratory and Biology Laboratory Faculty of Mathematics and Natural Sciences, Tanjungpura University, Pontianak. Dichloromethane and n-hexane fraction were obtained from the fractionation of methanol extract. Furthermore, both fractions in TLC and chromatogram profiles were visualized using UV 254 and 336 nm. Antibacterial test of D. piloselloides fraction was done by paper disc diffusion method. The concentration used in this study was 0.25; 0.30 and 0.35 g/ml, and as a comparison, Ciprofloxasin 0.005 mg/ml used as a positive control. Antibacterial activity test of dichloromethane fraction of dragon scales has only the ability to inhibit S. aureus, whereas the n-hexane fraction has no antibacterial activity against S. aureus and S. typhi. TLC test results showed that the dichloromethane fraction contains flavonoids compounds, while the n-hexane fraction contains terpenoids compounds

Get PDFEthnomedicine is a branch of medical anthropology which discusses the origin of diseases, their causes and treatment in accordance with a particular community group. This research conducted to find out the types of plants utilized as medicine for internal diseases by the Tabun Dayak in Sungai Areh Village, Sub-District of Central Ketungau. Sintang Regency, the benefits and the ways of processing. The research was carried out from March until June 2015 in Sungai Areh Village. The respondents were selected through the snowball method, while information about traditional medicine was obtained from interviews with the respondents. The data were analyzed using both qualitative and quantitative analysis. The qualitative analysis was conducted to find out the types of plants, parts that were used and the processing methods. The quantitative analysis used the Frequency of Citation (FIC) and the Informant Agreement Ratio (IAR). The research found 28 species belonging to the 22 families. The most widely used family was theZingiberaceae which consisted of 4 types of plants. The most widely used part of the plant was the root. The most common ways of processing the plants were by boiling and grindingthem first. The category of plant utilization was divided into 6,i.e.to treat cancer, excretory system, digestive system, respiratory system, reproductive system, and circulatory system. The highest citation frequency in this research was 92.87%;the highest score of the Informant Agreement Ratio (IAR) was in the category of the excretory system disease, i.e. 0.952
Struktur Anatomi Akar, Batang dan Daun Anthurium plowmanii Croat., Anthurium hookeri Kunth. dan Anthurium plowmanii × Anthurium hookeri
Get PDFThe anthurium seedlings are not only supplied through vegetative propagation, but also through generative propagation, i.e. plant crossing that also functions to enhance the exotic values which are different from the parent anthurium. Crossing the parent anthurium not only produces new plants with a different morphology, but also affects the anatomy of the plant itself. This research aimed to find out the anatomical structure of the root, stem and leaves of A. plowmanii and A. hookeri as well as the hybrid of both plants. The research was carried out from January to September 2015. The preparations of the organ incision were made using aparaffin method. The structure of vascular bundles of the A. hookeri stem showed a significant difference compared to the other two types. In addition, the ergastic substance was found more in the hybrid plant compared to both of its parent plants

Get PDFActinomycetes are microbes that potential to produce various bioactive compounds that have benefit to pharmacology. Porifera is one of marine organism that associated with Actinomycetes. The research was conducted to determine the genera of Actinomycetes associated with porifera (Axinella spp.). Isolation was done by using pour plate and streak plate method on starch-casein agar (SCA). The preparation of microscopic speciments used slide culture method. The isolates were observed and identified by using characteristic of macroscopic, microscopic and biochemical test reaction. The isolation of Actinomycetes associated with porifera (Axinella spp.) was found four genera of Actinomycetes i.e. Nocardia, Micrococcus, Streptomyces and Corynebacterium

PERTUMBUHAN TANAMAN SAWI HIJAU (Brassica rapa var. parachinensis) AKIBAT PERLAKUAN LOGAM BERAT KADMIUM (Cd)
Get PDFThe use of chemical fertilizers and pesticides in agriculture in a continuous and excessive manner can cause damage to the soil, one of which is the increase of the cadmium (Cd) content. The increased level of Cd will have an effect on plant growth. This research aims to find out the growth of mustard greens due to the treatment of heavy metal (Cd) and to determine the concentration of Cd absorbed by plants. The research was carried out from March to May 2015 in the Biology Laboratory of the Faculty of Matematics and Naturan Sciences, of Tanjungpura University Pontianak, and the Cd analysis was conducted in the Laboratory of Agricultural Product Technology of the Faculty of Agriculture of Tanjungpura University. The eksperimental design used was the Completely Randomized Design (CRD) which consisted of 4 treatments and 3 repetitions, i.e. 0 ppm, 50 ppm, 100 ppm and 150 ppm. Research findings showed that the addition of cadmium reduces the number of leaves, leaf area, fresh weight, dry weight and chlorophyllcontent in the plant. The higher the concentration of Cd given to the plant, the higher the concentration of Cd absorbed by green cabbage.The highest concentration of Cd absorbed by green cabbage was 0,220 ppm at a treatment concentration of 150 ppm

Get PDFHolothuria atra is marine creature which is potential as a source of antifungal material.This research aims to find out the antifungal activities of the extract of H. atra against the Malassezia furfur fungus that causes tinea versicolor. The extract of H. atra was obtained through a maceration method using methanol. The antifungal activities were tested using Kirby-Bauer disc paper diffusion method on the Saboraud Dextrose Agar (SDA) medium enriched with olive oil. The research used the extract with concentrations of 20%, 40%, 60%, 80%, and 100% with 2% of ketoconazole positive control and DMSO (Dimethyl Sulfoxid) negative control. The secondary metabolite test indicated content of alkaloids, triterpenoids, and saponins in the extract. The test results of antifungal activities showed that alllevels of concentration could inhibit the growth of M. furfur fungus characterized by the formation of a clear zone around the paper disc. The extract of H. atra is fungistatic with a very strong inhibition category. The concentration of 20% is the most effective in inhibiting the M. furfur fungus with a clear zone diameter of 22,16mm
