Samples were taken in non-probability sampling with purposive sampling, which is a science class of 38 students. The treatment given in this study is learning done online using google classroom application, all activities in google classroom on the concept of the human reproductive system. Results: The results of the analysis showed with t calculate (-15.39) greater than t table (-2.04). Based on data analysis and testing, it can be interpreted that there is an increase in student learning outcomes with google classroom-based online learning. The increase is seen from the N-gain value (0.57), which interprets learning outcomes in medium theories. Conclusions: Effectivity learning activities need to be presented by teachers in the face of pandemic situations, although they cannot be done for luring. Google Classroom based online learning can package distance learning more effectively, which has an impact on improving student learning outcomes.","PeriodicalId":33216,"journal":{"name":"Bioeduscience","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41420158","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}

Investigation of antibacterial potential of the coastal plants of Bidara Laut (Ximenia americana) has been carried out. Methods: Parts of the X. americana plant taken are Old Fruit, Young Fruit, Old Leaf, and Young Leaf. A total of ± 200 grams of each part of X. americana plant was taken to be extracted using maceration method. The antibacterial activity test was performed using the Kirby-Bauer disc diffusion method on Muller Hinton Agar (MHA) media. Observations were made in time units, namely every 6 hours of incubation for 24 hours. Results: The tested extract of plant parts of X. americana showed an inhibition zone against the growth of V. alginolyticus and V. parahaemolyticus bacteria in each replication in all-time units of observation. Of the four types of extracts tested, old leaves showed strong category resistance to V. alginolyticus with the highest clear zone diameter of 16 mm (average 14.67 mm) at 6 hours incubation. Young leaves gave the highest of 18 mm (average 16.33 mm) against V. parahaemolyticus at 6 hours incubation. Conclusions: X. americana plants have potential for antibacterial against Vibriosis disease in aquaculture. The ability of power to be seen tended to decrease for all tests until the end of observation, but until the end of observation, the ability of extract inhibition of all parts of the plant was still in the moderate to strong category.","PeriodicalId":33216,"journal":{"name":"Bioeduscience","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48124617","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}

Noni juice has the potential as herbal medicine which believed to reduce blood glucose levels. This study aims to determine the effect of noni juice on blood sugar levels on diabetic patients. Methods: This study used 16 respondents. They divided two groups, a control group and a treatment group. Each group consists of 8 respondents. The intervention group received 150 ml of noni juice which was given once a day for ten days. Glucose testing was carried out by the glucose-check method. The blood was taken from the respondent's fingertips capillary. The blood glucose levels between the control group and the intervention group were analyzed using independent t-test. Results: The average blood glucose level in the intervention group was 199.88 mg/dl, while the control group was 326.25 mg/dl. The test results of the mean blood glucose levels between the control group and the intervention group had a significant difference with a value of p = 0.003 (p ≤ 0.05). This indicates a significant effect between blood glucose levels in the control group and the intervention group. Conclusion: Noni can reduce blood glucose levels because it contains flavonoid. It has a hypoglycemic effect. Health workers can suggest consuming noni juice to decrease blood glucose in diabetic patients. \u0000 \u0000 ","PeriodicalId":33216,"journal":{"name":"Bioeduscience","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42542780","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}
