The research was conducted at the Balitkabi in February until May 2017. The experimental design used Randomized Block Design with two factors and four replications. The first factor is optimal environmental  (L1) and waterlogging environment (L2). The second factor is soybean varieties. The varieties used in this study were 3 varieties of soybeans (Grobogan, Demas 1, and Dega 1). In the optimal environment  (L1), the plants were planted in buckets that were planted under normal conditions . In the waterlogging treatment (L2), the polybags filled with soil and put into a wooden tub and added water. Waterlogging treatment is carried out after the plants are 21 days after planting, the wooden tub is filled with water to a height of 5 cm from the soil surface in the polybags (the plants are in submerged). The fertilizer used in this research was 15% N, 15% P2O5, 15% K2O with a dose of 1.5 g / polybags or the equivalent of 250 kg ha-1 which was applied at planting. Observations were made on the character of the pods per plant,  seeds per plant, seed weight, plant height, shoot fresh weight and shoot dry weight, root fresh weight and root dry weight and chlorophyll index. The waterloggingresulted in a decrease in yield components and soybean yield compared to the optimal environment. Waterlogging increased the root dry weight. Grobogan and Dega 1 varieties produced higher seed weights than Demas 1 varieties in waterlogging environments. Keywords: Yield and Yield Component, Soybean, Waterlogging","PeriodicalId":163464,"journal":{"name":"Konservasi Hayati","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116709002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These bacteria are known as beneficial bacteria in human life, both for humans themselves and for plants. The secondary metabolites of Streptomyces can be used as an antibacterial, antifungal, insecticide for plants and as an anthelmintic for humans. This research is motivated by the absence of research that discusses Streptomyces sp in the plant rhizosphere of the Liliaceae tribe in the Sumber bening village area. So that researchers are interested in doing this research. This study aims to determine the diversity of Streptomyces sp in the soil rhizosphere of Liliaceae plants in the Sumber Bening area. This study uses the Research and Development method. The study was conducted by isolating Streptomyces sp from the Rizosphere of three plants of the Liliaceae tribe, namely shallots (Allium cepa), Onions (Allium fistulosum) and Kucai (Allium schoenoprasum L) using YPGA medium (Yeast Peptone Dextrose Agar) and pouring down isolation techniques. After the isolates are obtained, the isolates will be purified by means of a scratch technique. Pure Streptomyces sp isolates were identified based on their morphological characteristics both microscopically and macroscopically. The results showed that there were 11 species of Streptomyces sp found in three Liliaceae plant rhizosphere with 6 species found in the onion rhizosphere, 3 species found in the leek rhizosphere and 2 species found in the rhizosphere of chives. There are Streptomyces griseourubiginosus, Streptomyces albovinaceus, Streptomyces griseus, Streptomyces albohelvatus, Streptomyces viridaris, Streptomyces hirsutus, Streptomyces nigrescens, Streptomyces herbaricolor, Streptomyces aureofaciens, Streptomyces nigrogriceolus,dan Streptomyces albolongus.","PeriodicalId":163464,"journal":{"name":"Konservasi Hayati","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131017840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Habitat rangkong gading tersebar di lima wilayah negara, yaitu Myanmar, Thailand, Malaysia (semenanjung Malaysia dan Serawak), Brunei, dan Indonesia (Sumatera dan Kalimantan). Kawasan Geopark Silokek, Kabupaten Sijunjung, Sumatera Barat merupakan salah satu wilayah yang teridentifikasi sebagai habitat rangkong gading. Selain bentuk fisiknya yang unik, satwa ini memiliki fungsi ekologis sebagai pemancar biji di dalam hutan.

Data yang digunakan adalah citra Landsat OLI 8 dan data geospasial terkait Geopark Silokek. Penelitian ini bertujuan untuk menentukan Kawasan prioritas konservasi Rangkong gading di kawasan Geopark Silokek. Dengan menggunakan algoritma MaxEnt (maximum entropy) berdasarkan titik satwa, maka dapat diprediksi probabilitas persebaran habitat rangkong di kawasan Geopark Silokek. Berdasarkan hasil penelitian, wilayah yang potensial untuk konservasi rangkong di kawasan Geopark Silokek terdapat di Kawasan perbukitan hutan lindung bagian utara dan timur laut.

The long-term use of antibiotics can cause resistance problems. As a consequent it is necessary to find the alternative antibiotics that are derived from plants. The alternative antibiotics are considered safer, relatively cheap and easy to obtain. One of the herbal plants used is Baccaurea macrocarpa. The objective of this study was to identify the secondary metabolites of B.macrocarpa, the effect of methanol extract from B.macrocarpa leaves on the growth of Escherichia coli and Salmonella typhi bacteria and to measure the optimal concentration of the sample to inhibit the growth of E.coli and S.typhi bacteria. The research has been conducted for 3 months at the Universitas Samudra laboratory. The method used was the well method with E.coli and S.typhi bacteria test. Each treatment of the methanol extract of B. macrocarpa leaves with a concentration of 20%, 30% and 40% (g/mL). Positive control was ciprofloxacin and negative control was sterile distilled water. The results obtained the concentration of 40% (g/mL) as the optimal concentration to inhibit the growth of E. coli and S.typhi bacteria with the resulting inhibition zone of 6.3 mm and 5 mm.
