Abstract

Studies on the therapeutic use of insects and insect products have been neglected compared to the use of other animals or plants.This study aims to determine the antibacterial and antioxidant potential of ants extracts. Preliminary study related to antibacterial and antioxidant screeningof 17 extracts of ant colonies that belongs to 8 species were performed by Thin Layer Chromatography (TLC)-Bioautography. Antioxidant activity was measured by DPPH free radical scavenging method. The antibacterial activity was done against three pathogenic bacteria, i.e Bacillus subtilis InaCC B-1, Staphylococcus aureus InaCC B-4 and Escherichia coli InaCC B-5 were performed by non-eluted TLC-autobiography assay. The minimum inhibitory concentration (MIC) and IC50 values of DPPH radical scavenging activity of active extracts were determined by microdilution in 96-well microplate. The results showed 6 extracts active against B.subtilis, 5 extracts active against S.aureus. The lowest MIC value was 512 µg/ ml.  Ten extracts had the antioxidant activity with various IC50 values. The extracts of ants might be used as bioactive resources for antibacterial and antioxidant.

Abstract

This research aims to see the land use change within ethnobotanical perspective. According to observation, interview, and Participatory Rural Appraisal (PRA) it was known that land in Enggano Island have been changed, even the sacred forest transformed, into kebun/garden and ladang/field. The changes of land use was related with demography, economic, and socio-cultural changes in society. Social change affected the species that were planted by the community. The species with a high economic value and a quick harvest and did not need extra treatment planted by local people to replace the previous plants. The other impact that arises is the exixtence of local initiative to restore areas that should functioned as a forest.

Abstract

This research was aimed to discover the traditional knowledge of Enggano people when using plants as concoction after giving birth. Data was collected through in depth interview, open-ended, and literature studies. The results showed that Enggano people used specific plants as concoction in childbirth process. There were two types of the concoction. The first was used after giving birth to 40 days, jarak pagar or tiarak (Jatropha curcas L.). The second was used after 40 days to 60 days or after recovery, such as dukung anak (Phyllanthus niruri Linn.), kumis kucing (Orthosiphon stamineus Benth.), temu lawak (Curcuma xanthoriza Roxb.), alang-alang (Imperata cylindrica (L) P. Beauv.), banana (Musa sp.), kencur (Kaempferia galanga L.), turmeric (Curcuma longa L.), and ginger (Zingiber officinale Roscoe). Results from our literature studies confirmed the efficacy of plants used by Enggano people is scientifically acceptable. Further study on phytochemical aspects of these medicial plants is therefore required to be carried out.

Abstract

A quantitative study of epiphytic plants was conducted at the logged over forest in Kiyu, Meratus Mountain, Hulu Sungai Tengah, South Kalimantan. This study used a plot of 10 m x 500 m (± 0,5 ha), and divided into 50 subplot of 10 m x 10 m. The results showed that there were nine species of six genera from three families of epiphytic plants found within the studied plot, with A grostophyllum bicuspidatum as the dominant species. The diversity index (H’) was of 1,85. The diversity of epiphytic plant in these plots was well represented based on the results of analysis of species area curve. Spatial distribution pattern of all epiphytic species was homogeneus, except for A. bicuspidatum. The number of epiphytic host plants observed was 22 individuals from six species of six genera, and five families, with Saurauia nudiflora (Acthiniaceae) was the dominant host plant.

Abstract

Ethnobotanical research on the utilization of plant species in Tau Lumbis village of North Kalimantan by Tagol and Akolod Dayaks ethnics has been conducted.Seventy seven species of plants have been recorded to be utilized by the people for various purposes from medicinal to magical-supranatural. Some literature reviews suggested that there was correlation of traditional knowledge and modern science in plant utilization by these ethnics.
