Rhodamine B is known to be difficult to degrade naturally thus causing a lot of damage, both to the environment and human health such as respiratory tract infection, skin irritation, digestive tract irritation, and eye infection. This study aims to find and determine the type of mangrove root symbiont bacteria Avicennia marina from Panipahan Village that can degrade Rhodamine B. This research is divided into several stages, namely sampling, isolation, purification, characterization of colony morphology, Rhodamine B biodegradation test through the overlay method, gram staining, biochemical tests, and molecular tests to determine the type of bacteria. The results obtained 16 isolates of symbiont bacteria that were successfully isolated from the roots of the Avicennia marina mangrove in Panipahan Village. Of the 16 isolates of symbiont bacteria, only 2 isolates have the potential to degrade Rhodamine B. The results of the biochemical activity test showed positive results in the Catalase, TSIA, motility, and O/F tests on RA5 symbiont bacterial isolates, while the citrate test showed negative results. For RA16 symbiont bacterial isolates, it is known that only the O/F test shows positive results, while the catalase, TSIA, citrate, and motility tests show negative results. The results of bacterial characteristics obtained are that the RA5 symbiont bacterial isolate belongs to the Bacillus circulans type and the RA16 symbiont bacterial isolate belongs to the Bacillus insolitus type. So, it was concluded that there were 2 bacterial isolates of Avicennia marina mangrove root symbionts in Panipahan Village, Riau that were able to degrade Rhodamine B.","PeriodicalId":321640,"journal":{"name":"Biodidaktika : Jurnal Biologi dan Pembelajarannya","volume":"120 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140475374","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 study was conducted at one of the state high schools in Serang. The study cohort comprised 71 students enrolled in class XI, specializing in Mathematics and Natural Sciences, and a teacher in Biology. The data collection methodology employed in this research involved conducting structured interviews with the biology educator and survey questionnaires among students. The stages in carrying out data analysis are data reduction, data display, and the iterative process of drawing conclusions and verification. The results of this research showed the importance of students' conceptual understanding of cell concepts, as evidenced in the data analysis of students who have a low level of conceptual understanding. The low understanding of the concept is caused by several factors, including cell concepts being too complex and abstract, dominant learning not being interactive, cell concepts being conceptual, and difficulty understanding foreign languages or Latin. Based on the results of interviews with biology teachers, several obstacles result in students' low conceptual understanding of cell concepts, including students being less interested in seeking additional explanations regarding cell concepts, students having low memory ability in studying the lesson concepts that has been presented by the teacher, and still a lack of availability of teaching aids in schools for cell concepts.","PeriodicalId":321640,"journal":{"name":"Biodidaktika : Jurnal Biologi dan Pembelajarannya","volume":"112 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140475557","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 aimed to determine the correlation between naturalistic intelligence and problem-solving ability through environmental photovoice project. Correlational research method was used in this study with purposive sampling technique. Population were 10 th grade students of senior high school with specific science class as a sample. Naturalistic intelligence was measured by using naturalistic questionnaire. The problem-solving ability indicates in photovoice project and measured by using a photovoice assessment rubric developed based on problem-solving indicators. The results showed that the average of students’ naturalistic intelligence was 75.82 in score, it’s mean that students’ naturalistic intelligence belong to high criteria. The average of students’ problem-solving skills was 66.12 in score belong to high criteria as well. The result of this research shows the value of correlational coefficient was 0.582. This means that there was strong positive relationship between naturalistic intelligence and the problem-solving skills through photovoice project on the environmental topic. These findings indicate that naturalistic intelligence are closely related to problem-solving skills.

As a result, it is important to identify the issues arising in order to select the most suitable solution to resolve them. The study aimed to identify problems with learning urban biology at one of the senior high schools in Jakarta and to find answers to those problems. The research method is using a case study method; a type of research that involves an in-depth examination of one individual, a group, an organization, and so on over a set period of time. The study's data collection methods included observation and interviewing. The study's findings reveal the following issues in learning biology at one of the senior high schools in Jakarta: 1) The biology program's implementation on practical indicators, 2) The redesigned 2013 curriculum, which is considered inconvenient for students and teachers to use, 3) Learning media selection and 4) Student learning interest. The solution to the problems of learning biology at senior high school in Jakarta is to understand the concept of implementing the 2013 curriculum so that it can provide innovative learning methods, can optimize the learning media that are being used, and understand the cognitive development of students with good communication skills.","PeriodicalId":321640,"journal":{"name":"Biodidaktika : Jurnal Biologi dan Pembelajarannya","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125479929","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}
