Abstract

Capsicum annuum (curly red chili) is an important commodity for the community. The addition of chemical pesticides is used by farmers to increase plant disease resistance. The use of chemical pesticides is harmful to the environment and can have long-term effects if consumed. Therefore, biopesticide innovation is needed. Black Soldier Fly (BSF) is an insect that has bacteria and fungi in its gut. Bacteria and fungi found in BSF intestinal isolates can function as antimicrobials for plants. Because of this, in this study investigated the effect of the bacteria and fungi Trichoderma viride in increasing disease resistance in C. annuum plants. There were 4 treatments in this study, namely the administration of chemical fungicides, BSF bacterial formula, T. viride. BSF, and a mixture of bacteria and T. viride BSF. The results obtained were analyzed by calculating the Intensity of Attack (IS) score, microscopic observations in the laboratory, and statistical tests. The IS score of the control plants was 75.0%, the fungicide treatment was 37.5%, the bacterial treatment alone was 33.3%, the T. viride treatment was 19.4%, and the mixed treatment of bacteria and T. viride was 4.2%. All plants were attacked by leaf spot disease by Cercospora sp. Control plants were attacked by Sclerotium rolfsii fungus wilt and powdery mildew by Leveillula taurica and jaundice. Jaundice also attacked plants treated with T. viride only and bacteria only. The normality and homogeneity tests show that the data is not normal and not homogeneous but H1 is acceptable based on the Kruskal Wallis test. The conclusion of this study is that bacteria and T. viride from BSF are able to increase disease resistance in curly chili plants, but are not yet effective in preventing disease caused by Cercospora sp.

Abstract

Genetics is a part of biological science that contains topics such as genetic structure, protein synthesis, cell division, and inheritance of traits. Genetics is one of the most commonly found misconceptions and difficulties in learning this material due to its complex, abstract and rapid development. To overcome these problems, it is necessary to analyse TPACK and analyse various learning strategies used in teaching genetics so that it can be taken into consideration for teachers in teaching genetics in the classroom. This research uses descriptive qualitative method by collecting relevant research in the form of national and international articles available on various websites. From the results of the research, it was found that teachers have applied a variety of models, methods, and media in learning genetics. The success in this learning process certainly depends on the teacher's TPACK analysis skills so that the teacher not only pays attention to the content but also can adjust it to the needs of students.

Abstract

This study aimed to analyze students' oral communication skills using the Citizen Science Project (CSP) based digital encyclopedia of mammals in learning. This research combines digital technology, community involvement, and the development of scientific communication skills as a novelty. The method used was descriptive quantitative with data collection techniques through observation. The research subjects consisted of 30 prospective teacher students of the Biology Education Study Program at a private university in Bandung. The instrument used was an observation sheet on oral communication skills. The results showed that most students scored good or sufficient. The average value on indicators 1-6, namely being able to provide information or ideas by 75%, including the good category, mastering the material to be used as presentation material by 70%, including the sufficient category, delivering report results systematically and clearly by 75% including the good category, questioning skills by 70% including the sufficient category, being able to answer questions by 75% including the good category, and confidence by 70% including the sufficient category. The percentage value of the active indicator in group discussions is 95%, which is included in the very good category. Based on these data, communication skills are critical because they allow students to convey ideas, work together, and exchange information. Students' oral communication skills can be improved by continuing to train and provide opportunities for students to communicate orally on an ongoing basis based on CSP.

Abstract

The research was motivated by the fact that biodiversity is declining; therefore, the involvement of all parties, including students, is needed to help save biodiversity. One way to do this is to implement meaningful learning by utilizing the closeness of students and gadgets through the application of personal digital inquiry-integrated citizen science projects in the classroom, which involve experts in carrying out biodiversity conservation projects in the form of a "digital herbarium" uploaded on Instagram. Students’ responses are important as a reference to the extent to which PDI learning integrated with CSP has succeeded. This study aims to analyze students’ responses to Personal Digital Inquiry (PDI) learning integrated with the Citizen Science Project (CSP) on biodiversity material in grade X high school students. This research is a descriptive study using a survey method. Questionnaires were used to collect research data. A total of 42 respondents participated in this study. The questionnaire contains statements about the implementation of learning using six indicators, which were compiled into 34 statements using a Likert scale. The results show a score of 79.73, which is considered good. Students feel enthusiastic and happy to participate in learning, get new experiences interacting with scientists and the surrounding community, increase closeness with teachers and colleagues, and increase awareness to maintain biodiversity by utilizing social media.

Abstract

Education in the era of digital technology has become a challenge for teachers and lecturers in how this technology can develop comprehensive knowledge and global insight. The purpose of this study is to improve learning achievement through the cognitive process of students in cell metabolism lectures using Interactive Digital Teaching Material (IDTM). The study involved 40 Biology Education students who were taking the third semester at one of the Private Universities in Bandung, West Java. The implementation of lectures and instruments to measure students' cognitive processes is based on the framework of the 1992 Marzano Learning Dimension. The results of the analysis showed that the N-gain value of Acquire and Integrate Knowledge and Extend and Refine Knowledge obtained a percentage of (28%-26%) on low criteria. While Using knowledge with a percentage of N-gain value (32%) on medium criteria. These results illustrate that IDTM facilitates students to train their cognitive processes toward better learning achievement

Abstract

Creativity skills are one of the essential skills to face the VUCA World. Improving creativity skills is hampered by the large number of students and learning conditions that are less demanding of the creative process in the class. This research aims to measure the effectiveness of the Botanical Eco-gamification program to improve creativity skills. The ADDIE research approach was used to redesign the Botanical Eco-gamification program so that it can improve creativity skills. This research produced test instruments, e-LAD and questionnaires to measure creativity skills in the program. The instrument developed has been proven valid and reliable for measuring originality, divergent thinking, convergent thinking and mental flexibility skills. The results of program implementation show that students' creativity skills have increased from before treatment in the sufficient category (54.2) to the good category (71.16) with the N-Gain achievement being categorized as medium (0.37). The majority of students (55.71%) reached mastery level after being given treatment. Almost all students (76.29%) stated that the program was good for improving creativity skills. Further research is needed to examine other 4cs competencies, ESD competencies, mastery learning and student's engagement in the Botanical Eco-gamification program
