Abstract

Abstrak: Suku Dayak Uud Danum di Kalimantan Barat memanfaatkan daun Ulin (Eusideroxylon zwageri Teijsm & Binn) sebagai tumbuhan obat dalam pengobatan tradisional untuk mengobati berbagai penyakit seperti diare, demam dan penguat badan. Penelitian ini dilakukan untuk menganalisis aktivitas ekstrak metanol dari daun ulin terhadap beberapa jenis bakteri patogen. Daun ulin diekstraksi dengan menggunakan metanol, kemudian diuji dengan metode difusi terhadap empat jenis bakteri yaitu Enterococcus faecalis, Staphylococcus aureus, Salmonella typhi pada empat level konsentrasi (1, 5, 10 dan 15 mg/ml) dan E. coli (50, 100, 150 dan 200 mg/ml). Hasil pengujian memperlihatkan bahwa semua level konsentrasi berpengaruh signifikan terhadap hambatan pertumbuhan bakteri patogen. Semakin tinggi konsentrasi ekstrak metanol daun ulin semakin tinggi diameter hambat yang dihasilkan. Diameter hambat tertinggi ditunjukkan oleh konsentrasi 15 mg/ml pada jenis bakteri S. typhi (12,33 mm) dan E. coli pada konsentrasi 200 mg/ml (22,67 mm). Hasil pengujian membuktikan bahwa daun ulin yang secara tradisional digunakan dalam pengobatan tradisional memiliki potensi sebagai antibakteri alami.Kata kunci: Ulin, antibakteri, Enterococcus faecalis, Staphylococcus aureus, Salmonella typhi, dan Escherichia coli.Abstract: Dayak Uud Danum of West Kalimantan traditionally use ulin leaves (Eusideroxylon zwageri Teisjm & Binn) to cure various diseases namely diarrhea, fever, and tonic. This present study aims to evaluate the activity of methanol extract of ulin leaves against several types of pathogenic bacteria. Ulin leaves were extracted with methanol; thus, the extract resulted tested in terms of disc diffusion Kirby and Bauer against four types of bacteria such as Enterococcus faecalis, Staphylococcus aureus, Salmonella typhi (1, 5, 10, and 15 mg/ml), and Escherichia coli (50, 100, 150, and 200 mg/ml). The results showed that all levels of concentration significantly affect the inhibition growth of pathogenic bacteria. The higher the concentration of methanol extract of ulin leaves used, the higher the inhibition zone produced. The highest response inhibition growth showed from the highest level of 15 mg/ml on S. tyhpi (12.33 mm), and E. coli was 200 mg/ml (22.67 mm). It suggested that the leaves of ulin which traditionally used as medicinal plant have the potency as natural antibacterial agents.Keywords: Ulin, antibacterial, Enterococcus faecalis, Staphylococcus aureus, Salmonella typhi, and Escherichia coli.

Abstract

People use medicinal plants to treat various diseases, one of which is gastric disorders. The study aims to analyze the use of medicinal plants to overcome gastric disorders by the Dayak Muara tribe in Kuala Dua Village, Sanggau Regency. The sampling method was purposive sampling, with the number of respondents was 10% of the total number of households in Kuala Dua Village (91 respondents). The information regarding the medicinal plants used by the Dayak Muara tribe to overcome gastric disorders such as diarrhea, intestinal worms, nausea and vomiting, constipation, gastric, flatulence, and stomachache was collected. Furthermore, data obtained analyzed for the use-value (UV), informant consensus factor (ICF), and fidelity level (FL). The Dayak Muara tribe in Kuala Dua village, Kembayan District, has used 17 species of medicinal plants to overcome gastric disorders. Curcuma longa is the plant with a high use value or UV (0.96), followed by Psidium guajava (0.89) and Zingiber officinale (0.45). The highest value of informant consensus factor or ICF includes the diseases category of diarrhea (0.98), gastric, stomachache, nausea, and vomiting, each of which has an ICF value (0.96), constipation (0.94), intestinal worms and flatulence (0.88). The plants with the highest fidelity level (FL) are Allium sativum, Cymbopogon citratus and Centella asiatica for gastric (100), Areca catechu for constipation (100), Moringa oleifera, and Theobroma cacao (100) for stomachache.

Abstract

Women often experience various health problems with their reproductive organs. They also have to take several treatments during postpartum and infant care. In the community, these treatments generally use medicinal plants and become local knowledge. This study aimed to document the local knowledge of Tanjung Merpati Village community in using medicinal plants for postpartum and infant care. We interviewed a total of 96 respondents, who are the general public in Tanjung Merpati Village. The data obtained were analyzed in the form of use-value (UV), informant consensus factor (ICF), and fidelity level (FL). The analysis results showed 22 species of medicinal plants used for postpartum and infant care. Plants such as kunyit kuning (Curcuma longa), cokur (Kaemperia galanga), entomu (Curcuma xanthorriza), and ginger (Zingiber officinale) have the highest UV values with values respectively (1; 0.96; 0.84 and 0.8). Baby haircare shows the highest ICF value. Several plants have the highest FL value (100), namely manjakani (Quercus infectoria) and asam kanis (Garcinia xanthochymus) (postnatal maternal care), ayau (Litsea sp) (baby poultice), kumis kucing (Orthosiphon aristatus), and coconut (Cocos nucifera) (fever in infants), jackfruit (Artocarpus heterophyllus) (treatment of baby's umbilical wound), lidah buaya (Aloe vera) (baby haircare), mengkudu (Morinda citrifolia) (stomachache and bloating in infants), as well as pisang (Musa sp) and cangkok manis (Sauropus androgynus) (enhance mother breast milk). Conclusions from the results of the study indicate that the people of Tanjung Merpati Village have local knowledge regarding postpartum and infant care, and this knowledge is still well maintained in the community.
