Abstract

Black garlic is an innovative product from garlic which contains S-allyl cysteine (SAC), flavonoids, and polyphenols during the aging process. The use of black garlic as a medicine has not been studied regarding its toxicity to the liver, so research is needed regarding the safety of its use through toxicity tests. The purpose of this study was to determine the effect of giving various doses of black garlic ethanol extract on liver histology and to determine the safe dosage of black garlic ethanol extract for consumption. The method used was the treatment of black garlic ethanol extract in the treatment group at doses of 5, 50, 100, 300, 600, 1000, and 2000 mg/kg BW orally in mice to determine the effect on the histology of the mice's liver. The results showed that the greater the treatment dose of black garlic ethanol extract, the greater the percentage of damage to hepatocyte cells in the form of necrosis in the histology of the mice liver. The highest percentage of damaged cells experiencing necrosis was 49% at a dose of 2000 mg/kg BW. The use of doses that are safe for consumption has not been found in this study due to cell damage found > 30% in the category of moderate damage. So further testing is needed using a lower dose or by administering the extract over a shorter period of time to determine the safe dose for consumption.

Abstract

Students are demanded by school assignments, and many of them feel under pressure when learning biology. This situation is a trigger for academic stress which has an impact on student achievement. This study aims to identify and compare the factors that influence academic stress on students studying biology at the senior high school level. The research method used was an ex post facto survey using a sample of 54 students with an age range between 16-18 years. Data were obtained through a questionnaire with 9 scales of answer choices and interviews. The results showed that the level of preference for biology subjects for both public and private high school students was quite good, but most students experienced academic stress with a fairly high category in terms of motivation, self-confidence, the education system, teachers, and school conditions. This research implies that teachers are expected to create learning strategies by paying attention to the psychological conditions of students so that student learning outcomes can be maximized.

Abstract

EMKONTAN is a student-centered learning model, which is oriented in creative learning, problem-solving (problem-based learning), collaborative learning, and giving opportunity for students to improve their environmental literacy. This study aims to analyze the validity and practicality of the EMKONTAN model in improving creativity, collaborative skills, and environmental literacy of prospective biology teachers. This study was carried out in the even semester of the academic year of 2020/2021 at IKIP Budi Utomo Malang and Faculty of Teacher Training and Education, Universitas Muhammadiyah Malang. This study involved 150 students in an even semester (Semester II) thru total sampling. Validity instruments used in this study comprised validation sheets for material, method, and media experts. Meanwhile, the instruments for practicality used observation sheets which were focused on the learning implementation, relevant student activities, and obstacles found during the learning processes. The results of the EMKONTAN model indicate that the model has content validity, constructs, and faces that are very feasible to be implemented in the learning process. Additionally, the results of practicality for the EMKONTAN model involve the implementation for each syntax with an average score of <3,6 in a very good category; the students’ activities are in a very active category with the average score of <85%, and the obstacle found is pandemic period; thus, online learning is required. Yet, the risks can decrease the effectiveness of learning. The implication of this research is that the application of the EMKOTAN model in universities by lecturers in related subjects will support efforts to increase environmental literacy for prospective biology teacher students.

Abstract

The 21st-century education requires students to be able to master 21st-century skills, namely communication and collaboration skills. Communication and collaboration skills are very important for students to develop their personalities in learning, because they cause individual and group interaction to gain knowledge and learning experience from each other. 21st-century skills can be practiced through the study of biology, because biology has values of scientific nature, cooperation, respect for the opinions of others, and openness to various phenomena that have just occurred. This study aims to measure the influence of problem-based and project-based learning on the communication and collaboration skills of grade X students of SMA Negeri 10 Malang. The implementation of this study used the Problem-Oriented Project-Based Learning (POPBL) model to direct students to create creative products. The method used in this study is a quasi-experimental research using the pretest post-test nonequivalent control group design. Communication and collaboration skills were measured using instruments in the form of self-assessment and peer assessment questionnaires. The results of the questionnaire were analyzed using the analysis of covariance (ANCOVA) test. The results of the study showed that the implementation of Problem-Oriented Project-Based Learning (POPBL) has a significant effect on students' communication and collaboration skills. These findings suggest that problem-based and project-based learning models can develop students' communication and collaboration skills.

Abstract

Based on the problem analysis, 10th-grade students at SMAN 1 Talawi show low critical thinking and problem-solving skills. This research aims to determine the level of validity, practicality, and effectiveness of developing biology teaching modules based on the SETS model to enhance students' critical thinking and problem-solving abilities. The type of research used is research and development with the Plomp model. The research data were analyzed using a Likert scale and t-test. The research results show that the biology teaching module based on the Science, Environment, Technology, and Society (SETS) model has a validity score of 87.91%, with very valid criteria. The practicality assessment shows a score of 84.52% with a very practical criterion. The average score for the critical thinking ability test is 83.85, and the average score for the problem-solving ability test is 83.00. These scores indicate that the effectiveness assessment falls into the high criterion with a very effective interpretation. The results of the t-test show that the P-value < α, so the alternative hypothesis (H1) is accepted. So, it can be concluded that the biology teaching module based on the SETS model that has been developed falls into the category of very valid, very practical, and very effective for enhancing the critical thinking and problem-solving abilities of tenth-grade students. The use of technology in this module is one of the novel aspects, where students are involved in exploring and analyzing issues about ecosystems and environmental changes through technology.

Abstract

In an era that requires a balance between theory and practice for effective teaching, pre-service teachers need the skills to design integrated, contextual, and meaningful learning experiences. This study examines the impact of implementing a Hybrid Collaborative Learning-based Lesson Study, oriented toward Wahdatul Ulum, on the lesson planning skills of pre-service biology teachers. The study employs a mixed-method approach with a parallel convergent design. Quantitative data were collected through questionnaires administered to 83 students at the end of the Biology Lesson Planning course at a State Islamic University in North Sumatra, while qualitative data were obtained through semi-structured interviews. The instruments used included Likert scale questionnaires and interview sheets. Data was analyzed using descriptive statistics and thematic content analysis. The analysis that the skills developed include formulating learning indicators and objectives, preparing materials, and designing learning steps in accordance with instructional syntax. Teaching practice also aided students in identifying challenges and learning from peer teaching. These findings suggest that an approach integrating theory, practice, and religious values is effective for developing the pedagogical skills, character, and professionalism of pre-service biology teachers.

Abstract

Senior and vocational high school students need to have strong environmental literacy (EL) to face environmental challenges and support the achievement of SDGs. High EL levels, supported by spiritual values, encourage students to make wise, environmentally friendly decisions and become agents of environmental conservation. Muhammadiyah schools play an important role in this regard through subjects that integrate religion and life. However, there has been no mapping of spirituality-based EL profiles among Muhammadiyah students in Malang Raya. This study aims to analyze the spirituality-based EL profile of Senior and Vocational High School Muhammadiyah students in Malang Raya. Using a cross-sectional survey approach, EL data from 584 students in grades X, XI, and XII in nine Muhammadiyah schools were collected and analyzed based on gender, class, and parental education. The results showed that there was no significant difference in EL between male and female students, as well as between classes. However, parental education, especially fathers and mothers who did not attend school, had a significant effect, although the effect was small to moderate. These findings suggest that life experience and parenting factors may influence students' EL, and that educational environment factors require further exploration to fully understand their influence.
