Abstract

The purpose of this study was to determine the learning interests, difficulties, and conceptual understanding of high school students on cell concepts. 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.

Abstract

This study aimed to determine students' written communication skills in writing practicum reports using flashcards. The research was conducted on grade 11th high school students with a simple random sampling technique. The research method used was an experimental method with Posttest-Only Control Group Design. In the experimental group, students were instructed to use flashcards to write their practicum reports, while the control group used conventional methods, writing on paper as usual. Students were then asked about their experience with a questionnaire. Students' reports on flashcards were scored and analyzed. The results showed that using flashcards significantly improved students’ written communication skills in writing practicum reports. This improvement was reflected in comparing post-test results between the experimental and control groups. In addition, students also responded positively to flashcards to improve their practicum report writing skills. The findings of this study contribute to the practical and theoretical understanding of effective teaching methods for writing, especially in the context of practicum reports. This study gives an insight into students' communication skills in writing that can be improved by applying innovative learning strategies.

Abstract

This study aimed to analyze the achievement of the Independent Curriculum implemented in Biology subject. The research method used is a survey conducted at one of the senior high schools at Lahewa, North Nias, Indonesia. The Independent Curriculum is the latest curriculum targeted by the Ministry of Education and Culture of the Republic of Indonesia to be implemented at every level of education. This curriculum optimizes intracurricular learning content. This is intended so that students can explore concepts and strengthen competencies according to the learning needs and interests of students. Biology lessons in high school as one of the intracurricular lessons are implemented based on the Independent Curriculum. The research instrument used is a measurement of the implementation of Biology learning designed based on the indicators of the Independent Curriculum. The data analysis technique was carried out qualitatively. The results showed that the Independent Curriculum in Biology lessons has been well implemented in high schools with the expectation that Biology teachers must be able to coordinate the learning process optimally. Thus, achieving the Independent Curriculum in Biology lessons must be supported by teacher competence to optimally direct students in the learning process.

Abstract

This study aimed to identify the diversity of macrofungi in the Paciran limestone mining area. This type of research is quantitative descriptive, identifying and describing the macrofungi diversity level in the Paciran limestone mining area. The method used is observation with data collection using a 1x1 meter plot technique and then continued to count the macrofungal species in the plot and analyze it using the Shannon & Wienner (1963) diversity index equation. In addition, the morphological characteristics of each macrofungi were noted and entered into the observation table. The research results showed that 10 species of macrofungi belonging to two divisions, namely Ascomycota and Basidmycota, were identified, totaling 377 individuals. The Ascomycota division has a low level of diversity with a value of 0.6, while the Basidiomycota division has a medium level of diversity with a value of 1.40. The diversity of macrofungi in the Paciran limestone mining area can be used as a contextual learning resource for lower plant botany to provide insight and increase contextual knowledge related to macrofungi diversity for biology education students.

Abstract

Jamu is an Indonesian culture still preserved by the community as an alternative treatment. One of the natural ingredients often used in herbal medicine is turmeric, which has various phytochemical compounds that benefit the body. This study examines the content of tannins, alkaloids, and saponins in traditional (conventional) instant powdered turmeric drinks and factory-made (commercial) instant sour turmeric powder drinks. Analysis of the phytochemical compounds in both samples was carried out qualitatively with various reagents used. Qualitative analysis was conducted based on changes in color or appearance in both instances. Based on the research conducted shows that, conventional and commercial turmeric powder is suspected of not containing tannin compounds but saponins and alkaloid compounds. The color analysis results show that traditional turmeric powder has darker color characteristics than commercial turmeric powder. It means that turmeric powder has phytochemical compounds, so it has the potential to be a functional drink that is beneficial to health.

Abstract

A study of the anatomy of the roots of Rhizophora mucronata in various waters, such as freshwater, river estuaries, and beaches, has not been widely carried out. Therefore, this study aims to identify the roots of Rhizophora mucronata in the mangrove area with the approach of plant anatomy as a source of learning biology. The root anatomy research method uses the fresh preparation method by making thin transverse sections on the roots and observing them under a microscope. The results of the study showed similarities in the anatomical structure of the roots, namely the epidermis, cortex, endodermis, xylem, and phloem. The difference in the results of this study is in the cortex section, which has a difference in thickness. With this, it can be concluded that there are differences in the anatomy of the roots of Rhizophora mucronata, which live in various waters with differences in the thickness of their cortex cells, and the results of this study can be used as a source of learning in the form of practical instructions. So, it can be concluded that this study can be used as a source of learning for valuable instructions on plant anatomy by students in the course of plant anatomy.

Abstract

This study aims to determine the effect of a guided inquiry learning model with a scientific approach on students' critical thinking skills on ecosystem material. The research was conducted in the even semester of the 2023/2024 academic year at one of the high schools in Jakarta, Indonesia. The research method used was a quasi-experiment with Nonequivalent Control Group Design. The research sample used was 52 students, with each class totaling 26 students using a simple random sampling technique. Based on the study's results, the experimental class's average value was 87.27, and the control class was 80.15. The t-independent test results show that the guided inquiry learning model, with a scientific approach, affects students' critical thinking skills on ecosystem material. Applying a scientific approach to the guided inquiry learning model can allow teachers to train and improve students' critical thinking skills. This learning model and approach encourages active participation, stimulates curiosity, and helps students gain a deeper understanding.
