Abstract

Escherichia coli is one of the bacteria that cause infections in the human digestive tract such as diarrhea, while Staphylococcus aureus is one of the bacteria that cause infections in the skin injury such as boils and pimples. This study used Syzygium zeylanicum leaves because it has potential as a antibacterial because it contains active compounds. This study aimed was determine the antibacterial activity of the fraction and the active compound in Syzygium zeylanicum leaves against Escherichia coli and Staphylococcus aureus. Research conducted on November 2015 to January 2016. The method used in this research were extraction by maceration, fractionation by liquid fractionation, antibacterial activity test, and determination of minimum inhibitory concentration with the diffusion method and isolation of active compounds by column chromatography method. The bacteria used in this test are Escherichia coli and Staphylococcus aureus. Data are presented in tabular form based on the average value of the inhibition diameter and deviation standard. The results of this research showed the water methanol active fraction against the bacteria that used in this test. The methanol water fraction had obtained one antibacterial compound in bottle 1,3,5 which shows the value of tannin Rf 0,416. The minimum inhibitory concentration of water methanol of water apple leaves is 1000 µg/mL for Escherichia coli and 500 µg/mL for  Staphylococcus aureus. The minimum  inhibitory concentration of the active  compound  to  Escherichia  coli  and  Staphylococcus  aureus  in  500  µg/mL.  The fraction and the active compound of water apple leaves have an antibacterial activity with Escherichia coli and Staphylococcus aureus and the active compound is tannin.

Abstract

Besemah tribe uses plants in addition to the treatment is also used for beauty treatments traditionally. Based on Agustina's (2015) study, 109 species of plants were used for traditional medicine by the Tribe of Besemah. Some species of Lamiaceae for traditional medicine such as patchouli (Pogostemon cablin (Blanco) Benth.), wild mint (Mentha arvensis L.), hoary basil (Ocimum americanum L.), mexican mint (Plectranthus amboinicus (Lour.) Spreng.), and sweet basil (Ocimum basilicum L.) contains essential oils that can be used for traditional cosmetic ingredients. Essential oils are stored in the secretory structure of plants in leaf and stem organs. This study aims to determine the type and location of the secretory structure of essential oils in some species of lamiaceae used for traditional cosmetics of Besemah Tribes Lahat’s District. The research was conducted in November 2016 until February 2017. The results showed that patchouli plants was found in the presence of glandular trichomes, oil cells, and idioblast cells. The wild mint plants have glandular trichomes. The hoary basil plants have glandular trichomes and oil cells. The mexican mint plants have glandular trichomes and idioblast cells. The sweet basil plants have glandulartrichomes.Keywords: essential oils, lamiaceae, traditional cosmetics, Besemah tribes,  glandular trichomes, oil cells, idioblast cells

Abstract

Campus of  Sriwijaya University in Indralaya , has a high diversity of flora including fern, especially the epiphytic ferns, whose existence is so widely found in oil palm plants.  Survey about  diversity of this epiphytic has been carried out  from July to November 2017, with aim to identifying the diversity of species of epiphytic ferns in oil palm plants on the campus of UNSRI Indralaya. The research method used is exploration method with direct collection technique from the field and then made herbarium. A total of 27 species of pteridophytes were collected from the study area. Floristic analysis of collected specimens was carried out to find out the families, genus and species. In this survey was  collected 27 species belonged to13 genera, 7 families such  Aspleniaceae, Blechnaceae, Davalliaceae, Lygodiaceae, Nephrolepidaceae, Polypodiaceae, and Vittariaceae. The most common types are Polypodiaceae is Drynaria quercifolia, Drynaria sparsisora, Microsorum pustulatum, Microsorum punctatum, Phymatosorus scolopendria, Polypodium verrucosum, Polypodium polysthicum,  Pyrrosia piloselloides, and Goniophlebium verrucossum. The most widely distributed species in oil palm is Davallia denticulata , Goniophlebium verrucosum, and Nephrolepis biserrata.

Abstract

This study is aimed to recognise the morphological characteristics of Nepenthes mirabilis and Nepenthes gracilis in peat swamp area including stem, leaf, tendril, pitcher, flower, fruit, and seed.  This study has been conducted in January  until April 2018, located in Petaling Village Tulung Selapan Sub-District, Ogan Komering Ilir, South Sumatera. This study uses an exploratory method and the the observation sample using the method of random plot is chosen by purposive sampling. Parameters observed morphological characteristics of Nepenthes include stems, leaves, tendrils, pitcher, flower, adn fruit, as well as measurement of environmental factors. Based on the study, the researcher obtained two types of Nepenthes which are Nepenthes mirabilis and Nepenthes gracilis in  peat swamp area of Petaling Village Tulung Selapan Sub-District, Ogan Komering Ilir. Nepenthes mirabilis has a teres stem, leaves that in the form of oblong to lanceolate, has a petiolate, the edge of the leaves is flat covered by smoothy hair, thick peristome in size of 0,4-0,5 cm. Meanwhile stem Nepenthes gracilis has triangular stem, leaves in formed of lanceolate, sessile, flat edge of leaves, thin peristome in size of 0,1-0,2 cm. The pitcher shape of Nepenthes mirabilis and Nepenthes gracilis are cylindrical, infundibulate, and waist. The flower of Nepenthes mirabilis and Nepenthes gracilis are compound in type of  raceme inflorescences. The fruit is formed as capsula, has four lobed, and contains numerous seeds. The seed is spindle-like and white colored.

Abstract

The research entitled Ethnobotanical study of Pandanaceae by the Besemah tribe in Lahat Regency, South Sumatra has been conducted form October 2018 to December 2019. The objective of the research were to inventory the species diversity of Pandanaceae and its traditional utilization by the local ethnic in the studied area. The research was conducted by  using survey method and field work to collect plant samples.  The   basic data of ethnobotany was collected by using  direct interview from respondents. The result showed that there were six (6) species of Pandanaceae such as;  Pandanus lais Kurz, Pandanus helicopus Kurz, Pandanus amaryllifolius Roxb. (two varieties; “large and small” size fragrant pandanus), Benstonea atrocarpa Griff, Benstonea affinis Kurz. and Freycinetia rigidifolia Hemsl. 71,4% of them were belonged to wild species and 28.8% were cultivated species. The trdaitional utilization of Pandanaceae was used for handycrafft (36.4%), building material (9,1%), medicinal & cosmetic ingredients, foodstuffs and customary materials (18.2% each). The Baeemah tribe was used leaves (75%) rather than other part of plant.

Abstract

The coal open mining is an activity that has an impact on the environment, including acid mine drainage (AMD). The management of AMD can be done by phytoremediation using Chinese Waterchestnut (Eleocharis dulcis Burm.f.) Trin. ex Hensch.) on system of constructed wetlands (CWs). So the research was carried out with the aim of evaluation the accumulation of heavy metals iron (Fe) and Manganese (Mn) which were absorbed in E. dulcis in constructed wetlands system at WTP Air Laya PT. Bukit Asam. The accumulation of Fe in the roots of E. dulcis was 986.42 ppm (w/w) while the accumulation of Fe in the leaves was 392.22 ppm (w/w). The accumulation of Mn in the roots of E. dulcis was 24.49 ppm (w/w), while the accumulation of Mn in the shoots was 96.83 ppm (w/w). E. dulcis is known to have the potential to increase AMD pH and reduce levels of Fe, Mn and SO42- so that it can meet the quality standards of coal mining activity wastewater. The accumulation of Fe and Mn in the roots and shoots of E. dulcis and on AMD can be used as an effort to monitor the success of AMD phytoremediation on Constructed Wetlands system at WTP Air Laya.
