Inability to properly connect concepts may cause misconceptions that will affect students' achievement. Therefore, the purpose of this study is to analyze students' misconceptions on the topic of cells using a four-tier multiple choice diagnostic test. The research method used is research and development. The subjects in this study were 36 students of class XI science at SMA Muhammadiyah 5 Rancaekek. The results of developing a diagnostic test using the content validity ratio (CVR) method produced a CVR value of 0.75 (CVR ≥ 0.672) and the content validity index (CVI) method produced a value of 0.87 so that the developed diagnostic test was feasible to use. The results of the analysis of misconceptions experienced by students showed that on the topic of chemical components making up cells 10.42%, cell structure 10.42%, cell function 13.89%, differences between animal and plant cells 17.36%, and bio-processes in cells 11.81%. Overall, the misconceptions experienced by students regarding cell material were 12.78% (misconceptions > 10%), which means that a misconception experienced by students was considered significant.","PeriodicalId":305827,"journal":{"name":"Quagga: Jurnal Pendidikan dan Biologi","volume":"2845 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127447738","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 phytochemical content of the extract was tested using the Thin Layer Chromatography (TLC) method. The type of research is a laboratory experiment using the Kirby Baeur disk diffusion method with swab technique with a series of extract concentrations of 1000 mg/ml, 500 mg/ml, 250 mg/ml, and 125 mg/ml, positive control (30% amoxilin), and negative control (DMSO 10%) with 4 repetitions. The phytochemical content of the ethanol extract of bajakah that was tested shows secondary metabolites of steroids, flavonoids, saponins, and alkaloids. Bajakah ethanol extract has the inhibitory potential against M. luteus for all test concentrations which fall under the moderate category. The diameter of the amoxicillin inhibition zone was still larger than the extract inhibition zone.","PeriodicalId":305827,"journal":{"name":"Quagga: Jurnal Pendidikan dan Biologi","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115355855","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}

This study aims to determine the antibacterial activity of guava leaf extract against the growth of the pathogenic bacteria Aeromonas hydrophila in vitro. The method used to determine the antibacterial activity of guava leaf extract is the disc diffusion method. The activity test used a completely randomized design (CRD) consisting of 4 treatments with concentrations of guava leaf extract, namely 30%, 50%, 100%, and aqua dest as a control. Guava leaf extract was dissolved using 96% ethanol by the maceration method. Each treatment concentration was tested for its inhibitory power by calculating the apparent zone diameter that appeared against Aeromonas hydrophila bacteria. The data obtained were analyzed using analysis of variance with a 95% confidence level and, if significantly different, continued with the LSD test. The in vitro antibacterial activity test showed that guava leaf extract had a very significant effect on the growth of Aeromonas hydrophila bacteria (p<0.01) with a concentration of 50%, resulting in the most effective inhibition Aeromonas hydrophilla bacteria growth with a clear zone formed 18.33 mm. Based on the study results, it can be concluded that in vitro guava leaf extract with a concentration of 50% can inhibit the growth of Aeromonas hydrophila bacteria with the most significant clear zone yield.","PeriodicalId":305827,"journal":{"name":"Quagga: Jurnal Pendidikan dan Biologi","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128318546","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}

This study aims to analyze the sociocultural characteristics of the local community related to learning that can sustainably support Tangkas Lake ecotourism. The research was conducted with a qualitative approach. Data were collected employing a participatory manner through focused discussions. In addition, data were also collected through in-depth interviews and semi-structured interviews using a questionnaire. In general, the knowledge of local people regarding ecotourism is in a low category. In terms of perceptions and attitudes, the people have good perceptions and attitudes regarding Tangkas Lake tourism activities. Men tend to have a more positive attitude than women. In contrast, women tend to have better perceptions regarding Tangkas Lake tourism. For this reason, efforts to strengthen (increase) public understanding are needed to improve local people's awareness of the importance of educational content in tourism activity. In addition, the community also needs to be facilitated to increase their understanding of ecotourism and seven tourism charming (sapta pesona).","PeriodicalId":305827,"journal":{"name":"Quagga: Jurnal Pendidikan dan Biologi","volume":"129 16","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133617015","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}

This research was conducted in class VII SMPIT Al Multazam Kuningan to develop flipbook-based learning multimedia. This research was conducted using the R&D (Research and Development) method which refers to the ADDIE model. The percentage of media validation scores by experts is 87% from linguists, 90% from content/material experts, and 89% from media experts. Furthermore, at the trial stage, flipbook-based learning multimedia received an assessment percentage of 89.8% for the material aspect, 87.55% for the language aspect, 88.9% for the media aspect, and 88.75% for the average percentage.

This research is a non-experimental study to isolate soil bacteria from Pracimaloyo public cemetery in the district of Kartasura. Skim Milk Agar (SMA) is used as selective media. Proteolytic capacity was determined using the proteolytic index (PI). Potential proteolytic bacteria isolates were identified based on morphology features and PI values > 2 were isolated from P23 and P22 isolates. Bacterial proteolytic isolates are dominantly colonies of white to yellowish with irregular and circular shapes. Gram-staining results indicated that bacterial isolates with proteolytic abilities are belong to Gram-negative bacili bacteria. The highest PI value of bacterial isolates exhibited by P23 isolates and possibly belong to the genus Bacillus.
