Wulandari — 2024-11-19

Teaching materials are a collection of books containing information or materials that are arranged in an orderly manner to support the learning process. The kapok plant found on the banks of the Aluh Aluh River, Simpang Warga Village, Banjar Regency, South Kalimantan, has the potential to be a source of learning based on local potential in the form of popular scientific books. This study aims to determine the population structure of kapok plants and determine the feasibility of popular scientific books on the structure of kapok populations as teaching materials for plant ecology. The method used is the 3-phase Plomp development method, namely preliminary research, prototype making phase, and assessment phase. The teaching materials in the form of popular scientific books that were developed have a validity score with very valid criteria and have a student readability score with very good criteria. So it can be concluded that the teaching materials of popular scientific books on the structure of kapok plant populations can be used as teaching materials in the learning process.

Phytocemical Screening and Toxicity Test of Ethanolic Extracts Phanera semibifida (Roxb.) Benth. Stem and Leaves from West Sumatra

Meyla Suhendra — 2024-11-19

Indonesian people use plants as medicine because they are considered to have fewer side effects. Phanera semibifida (Roxb.) is a climbing plant that has been used by the community to make therapeutic drugs. Phanera semibifida, especially species in western Sumatra, lacks information on phytochemical composition and toxicity capabilities. So the purpose of this study was to determine the phytochemical content, toxicity (BSLT), and biological activity of Phanera semibifida growing in western Sumatra. The BSLT approach was used in this study to conduct phytochemical screening and toxicity studies on leaves and stems. Phytochemical results were negative for alkaloids and steroids but positive for flavonoids, tannins, saponins, and terpenoids. Based on the BSLT experiment, it can be concluded that both ethanol extracts are highly toxic and show anticancer properties

Survey of the Importance of Using Basic Biomedical Science Lecture Guidebooks Containing Personality Types for Health Faculty Students

Arfatul Makiyah — 2024-11-19

In higher education, especially in the health sector, a deep understanding of the course material is the key to academic success. In improving the quality of student learning, the use of teaching materials is essential to achieve competency targets. However, each student has a different personality so that their learning style type is different. Based on this, it is necessary to develop more adaptive learning resources that not only include scientific materials, but also pay attention to the different personality types of students. This study aims to explore the importance of using basic biomedical science lecture guidebooks that are tailored to the personality types of students at the Faculty of Health. This research method uses a descriptive survey approach with a purposive sampling technique. A survey was conducted on a number of students to assess the effectiveness and needs of guidebooks designed based on personality types. The survey results showed that most students felt helped by the existence of guides that were in accordance with their learning characteristics, which ultimately improved understanding and academic achievement. It can be concluded that personalized teaching materials according to student personality are useful and needed in the learning process.

The Infact of the Project Based Learning (PjBL) Model on Strengthening the Pancasila Profile of Creative Thinking of High School Students

Education is an important factor in human life. Independent curriculum is present as a response to the tight competition for Human Resources, one of the goals of learning is to equip students with creative thinking skills. The PjBL model is a learning model that can bring out student creativity. This study aims to determine the effect of using project-based learning (PjBL) models on strengthening the Pancasila Profile in State Senior High School Students. This research method is a quasi-experimental with a pretest-posttest control group design. The research design used is Nonequivalent with a random sampling technique of 76 students selected as the experimental group and the control group. There were 7 test questions distributed, 20 student response questionnaires used, and 13 observation sheets used. Data analysis techniques are used to test the hypothesis. In testing this hypothesis, the technique used is the Sample T-test technique. The results of the study indicate that the use of the PjBL model can improve students' creative thinking skills. There is a difference in gain values between the experimental and control classes. The gain value of the experimental class is higher than the gain value of the control class, so this study can conclude that the PjBL model has a significant effect on students' creative thinking skills. This study emphasizes the focus of PjBL and other meaningful tasks, namely by providing opportunities for students to work independently in constructing knowledge to create products as part of the realization of the Pancasila profile competency.

Macrofungi Diversity in Mount Gede Pangrango National Park

Lilis Supratman — 2024-11-19

Macrofungi are easily observed biodiversity. Mount Gede Pangrango National Park is a complex research location for inventorying macroscopic macrofungi. The rainy season is a strategic time for abundant macrofungi research. The purpose of this study was to inventory macrofungi and their relationship to the role of macrofungi through literature studies. The method used in this study was the free roaming method with sampling using the purposive sampling technique. Observations were made when macrofungi were found on the path to the Cibeureum waterfall at an altitude of 1,625 m above sea level. Information about the role of macrofungi with comparative studies with literature. The results of the study of macrofungi identification was using the determination key on various applications of macrofungi. The result found 5 orders, 10 families, 15 genera and 19 species. The role of macroscopic fungi associated with macroscopic for consumption (Phillipsia, Laetiporus, and Lentinus), macroscopic herbal fungi (Microporus, Tatraea, Ganoderma, and Trametes), macroscopic pathogenic fungi (Phellinus), macroscopic wood-destroying fungi (Phellinus) and macroscopic bioluminescent fungi (Picipes and Mycena). It can be concluded that the most dominant order found is Polyporales, and the most dominant family is Polyperaceae. The role of macroscopic fungi in study site are for consumption, macroscopic herbal fungi, macroscopic pathogenic fungi, macroscopic wood-destroying fungi, and macroscopic bioluminescent fungi.

Development of a Sustainability Awareness Tool for High School Biology Students

Suci Siti Latifah — 2024-11-19

In the context of classroom-based learning, the majority of students tend to acquire cognitive knowledge. It is essential for students to not only acquire cognitive knowledge but also develop awareness of sustainability as a result of teaching and learning activities. The purpose of this study was to develop an instrument to measure sustainability awareness among high school students. Developing an instrument of sustainability awareness for students is important to measure and encourage their understanding and actions in preserving the environment sustainably. The instrument developed consists of three subdimensions: economy, society, and environment. This instrument assesses awareness of the concept of sustainable development and practices, attitudes, and moral values for sustainability at the individual level. This study used the Rasch modeling analysis technique. The instrument is a closed questionnaire containing 21 items using a 4-point Likert scale. The results of the Rasch modeling showed that the overall Cronbach's alpha reliability coefficient was in the "good" category, while the item reliability coefficient was in the "very good" category. However, the student reliability coefficient was in the "weak" category. The results of the instrument validity test showed four invalid items. These items showed ZSTD and Pt Mean Corr values that did not meet the established criteria. However, the existence of invalid instrument items and weak student reliability coefficients did not affect the overall quality of the instrument. Therefore, it can be concluded that the developed instrument is considered appropriate for measuring the sustainability awareness profile of students.
