It has some advantages such as biodegradable, and non-toxic because the main ingredients come from biomass and produce fewer pollutants. Anabaena sp. is Cyanobacteria that can be used as the main ingredient of bioethanol, its advantages are that it does not compete with food, its growth is fast and it contains carbohydrates. The purpose of this study was to analyze the carbohydrate content of Anabaena sp. The stages of the research carried out were Anabaena sp. cultivated for 30 days in freshwater using Walne media, then harvested. The collected biomass was then tested using proximate analysis with two replications. In this study, the data obtained in the form of growth of Anabaena sp. and carbohydrate content was presented in the form of tables and graphs. The results showed that Anabaena sp. which was cultivated for 30 days and harvested biomass was carried out in an exponential phase (day 14), had a carbohydrate content of 25.43 %, protein of 53.70 %, and lipid of 2.40 %. Based on the results of the study, it can be concluded that the biomass of Anabaena sp. has a carbohydrate content of 25.43 % and has the potential as the main ingredient of bioethanol.","PeriodicalId":378431,"journal":{"name":"EKOTONIA: Jurnal Penelitian Biologi, Botani, Zoologi dan Mikrobiologi","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131401849","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}

The data obtained were analyzed using the NTSYS 2.02i application. to get kinship. Morphological performance was analyzed descriptively. During the research, five fish species from the Familia Cyprinidae were found, including Barbodes binotatus, Barbonymus balleroides, Osteochilus vittatus, Puntius sp., and Rasbora argyrotaenia. The closest phenetic relationship is between B. binotatus and Puntius sp. with a similarity index value of 0.909. The furthest relationship between R. argyrotaenia and B. binotatus with a similarity index value of 0.742.

Leptospirosis occurs through humans contact with animals or the environment that have been contaminated by Leptospira. There are wide spectrum clinical manifestations of leptospirosis varying from self-limited to severe disease. Leptospira commonly enters human body through conjunctiva or injured skin, food or beverage contaminated with urine’s rat containing Leptospira. This disease is very difficult to be distinguished from other diseases such as meningitis, malaria, dengue fever, hepatitis and enteric fever. Clinical symptoms of leptospirosis are nonspecific and due to the difficulties in conforming the diagnosis so that resulted to the misdiagnosis of this disease. Microbiological examination is done by Rapid Diagnostic Test, Microscopic Agglutination Test, Polymerase Chain Reaction test and others.
