Penelitian ini bertujuan untuk menganalisis pola pemanfaatan tumbuhan obat suku Dayak Iban di Kapuas HuluPutussibau Kalimantan Barat terutama penggunaannya untuk mengatasi gangguan sistem pencernaan. Metode penelitian yang digunakan adalah purposive sampling dengan teknik wawancara semi terstruktur dengan target 100% responden KK. Lokasi penelitian di desa Lanjak Besar (dusun Tekalong dan Bejabang) dan Desa Sepandan (dusun Tematu 1 dan Tematu 3). Analisis data berupa pola pemanfaatan tanaman (Use value/UV, Informant concensus factor/ICF dan fidelity level/FL), dan hubungan antara karakteristik responden dan level pengetahuan tumbuhan obat (chi square test). Sebanyak 21 species tanaman obat digunakan oleh 60% responden untuk mengatasi masalah pencernaan. Jenis-jenis tanaman yang memiliki nilai penggunaan (UV) yang tinggi adalah bawang merah (0.53), pisang (0.5) dan jambu batu (0.44). Nilai tertinggi dari ICF antara lain untuk mengobati maag (1,00), sariawan (1,00), pencahar (1,00), susah buang air besar (9,98), dan masuk angin (0,98). Jenis-jenis tanaman yang memiliki nilai fidelity level (FL) tertinggi (100) adalah salam (diare), langsat (flatulence), leban (maag), jeruk sambal (sariawan), durian (sakit lidah), pisang dan papaya (susah buang air besar), sahang putih, sugan dan rumput cupak (sakit perut), bawang merah (masuk angina), putri malu (sakit gigi), japa dan bawang lembak (ambein/wasir), temulawak dan kencur (penambah nafsu makan), serta kucai sebagai obat pencahar. Penggunaan tertinggi adalah famili Zingiberaceae (4 species), habitus herba (43%), bagian daun (29%), dan dengan cara diminum (59%).

Plants have an essential role in people's lives because of their benefits and properties, such as for medicinal properties. In Landak District, only limited studies on medicinal plant had been carried out. This study analyzes the species of medicinal plants used by the Dayak Kanayatn tribal traditional healers in Tonang Village, Sengah Temila District, Landak Regency. The sampling used the snowball sampling technique. The results found that traditional healers of Dayak Kanayatn in Tonang Village used a total of 60 species belong to 36 families. The most utilized families (8.47%) are Zingiberaceae and Asteraceae. The extensive use of plant habitus is herbs (41,67%). Leaves are the most dominant plant part used (44.78%), while the highest processing method was boiled (39.74%). The highest form of use was drinking (38.67%), the most common location of plants was in the yard (67.74%), the highest plant status is cultivated (52%), and the highest form of the potion is in the form of a mixture (72%). The result shows that the traditional healers in the Dayak Kanayatn community in Tonang Village, Sengah Temila District, Landak Regency, still use medicinal plants to overcome health problems and treat disease.

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.
