This study aimed to determine the behavior of Lutung Budeng in the Adinuso Subah forest, Batang Regency. The study was conducted from January to December 2019. Lutung Budeng behavior is observed directly in the field using the roaming or exploration method. The equipment used were the digital singlelens reflex camera of the Canon EOS 650 D, telephoto tamron 70-300 mm, tripod, Sony handycam HRD- PJ410, compass, and Nikon Binocular A211 16x50 mm. The recorded vocal of Lutung Budeng was analyzed using Audacity. The data observed were the behavior of moving places, feeding, grooming, resting, playing, and vocalization. The data obtained were analyzed by means of descriptive qualitative. The results showed that in the Adinuso forest, the feeding behavior of Lutung Budeng did not interact with visitors or humans to get feed. Lutung Budeng more often feeds young leaves. It can be concluded that the behavior of Lutung Budeng in Adinuso Subah forest, Batang Regency is relatively the same as the behavior of Lutung Budeng in general. The behavior of Lutung Budeng in the Adinuso forest includes moving places, feeding, resting, grooming, vocalization, and playing.","PeriodicalId":9004,"journal":{"name":"Biotropika: Journal of Tropical Biology","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73489901","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}

In Bali, D. imbricatus was found in Bukit Tapak, Tabanan Regency. This species is one of the dominant species in Bukit Tapak. This study aimed to determine the genetic variation of D. imbricatus in Bukit Tapak using molecular markers RAPD (Random Amplified Polymorphic DNA). The genetic diversity of D. imbricatus needs to be studied to obtain the information used for the conservation of this species. Leaf samples were taken from Bukit Tapak, Candikuning, Baturiti, Tabanan Regency, Bali. DNA was extracted using the CTAB method, followed by extraction using chloroform: isoamyl alcohol. DNA precipitation was carried out using ethanol. RAPD analysis was performed using polymerase chain reaction (PCR) using four primers. PCR products were visualized using agarose gel electrophoresis and ethidium bromide staining. The results showed that the amplified DNA bands ranged from 1 to 5 bands with DNA band sizes ranging from 230 bp - 422 bp. Only OPA4 and UBC106 primers can be used to detect D. imbricatus diversity based on the H, D, and R values. The detected genetic variation is low, as indicated by an average polymorphism of 32.5% and similarities between samples ranging from 0.51 to 1","PeriodicalId":9004,"journal":{"name":"Biotropika: Journal of Tropical Biology","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78051743","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}

On the other hand, bacteria resistance provides an opportunity to search for antibacterials from natural material without threatening plant biodiversity. The purpose of this study was to characterize and test the antibacterial activity of endophytic bacteria from the fruit of the Arecaceae family against antibiotic-resistant bacteria Escherichia coli. The method used was direct culture on the growth of media in the laboratory by first sterilizing the surface of the flesh of the samples, such as Aren (Arenga pinnata), Coconut (Cocos nucifera), and Sago (Metroxylon sagu). The pure isolates obtained were characterized according to Bergeys Manual for Identification by performing Gram stain, catalase, and coagulase test. The results obtained were five isolates with codes A1, A2, K, S1, and S2 with variation in morphology colonies. Gram staining, catalase, and coagulase verification of the five isolates were groups of Grampositive cocci, catalase-positive, and coagulase-negative bacteria. Based on tests carried out on the characters of the endophytic bacteria, it was obtained a close relationship with the genus Staphylococcus. The results of the inhibitory activity test showed that Staphylococcus sp. K with the highest criteria of 43.26 mm and Staphylococcus sp. A1 with the lowest inhibition criteria with a value of 24.73 mm. Both are categorized as very strong inhibition criteria.","PeriodicalId":9004,"journal":{"name":"Biotropika: Journal of Tropical Biology","volume":"432 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76649388","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}
