Abstract

Phytochemistry course is a compulsory course in Bachelor of Pharmacy which should combine theory and practice. Phytochemistry courses are divided into Phytochemistry 1 and Phytochemistry 2 courses in the form of theory (2 credits) at several leading universities in Indonesia. The curriculum in the Pharmacy department or study program at universities in Indonesia does not all combine theory and practice in Phytochemistry Courses (University of Indonesia, Bandung Institute of Technology, Udayana University) although there are several universities using a 1 credit practicum in it such as UGM, UNAIR, and UNPAD. The purpose of this study is to model the practicum of Phytochemistry Course based on the local wisdom of the Sasak Tribe in West Nusa Tenggara Province by taking samples of medicinal plants from each regional district in NTB. This research is a literatured study with studies from various articles and practicum methods. By taking samples of mangosteen skin, betel leaves, castor bean, single garlic, soursop leaves, bay leaves, banten leaves, bebele leaves, tamarind leaves, and telang flowers. Practicum can develop higher-order thinking skills, this is because through practicum activities students are guided to carry out processes that can support thinking skills. The application of practicum will also link local wisdom, not only accept as a whole but can independently determine the sample of medicinal plants for extraction, so as to develop thinking skills in decision making in determining alternative compounds to be used.

Abstract

Teaching computational physics and developing programming skills remains a significant challenge for many undergraduate programs worldwide. This study presents an innovative approach implemented at the University of Mataram, Indonesia, to optimize Pascal programming instruction for physics students. Various artificial intelligence (AI) techniques were utilized to assist students in developing more complex programs. This enabled the generation of customized lesson plans with interactive tutorials, coding exercises, and simulations tailored to each student's needs. Throughout the semester, the system continuously monitored student progress and adjusted instructional materials accordingly. The analysis of Mann-Whitney test results for Computational Physics scores among Classes A, B, and C revealed no statistically significant differences between the groups, with median scores consistently at 80 and p-values exceeding 0.05. However, an examination of the theoretical section of the final examination showed an overall improvement in average scores compared to the previous year, with Class A achieving the highest mean score of 84%. Additionally, the practical programming section demonstrated increased pass rates across all three classes, with Class B achieving the highest pass rate at 92%, followed by Class A at 88% and Class C at 82%. Student feedback indicated high levels of satisfaction with the approach, citing increased engagement and motivation. The study highlights the potential of leveraging AI techniques in generating personalized programming examples for computational physics education, enhancing comprehension of theoretical concepts, and facilitating the development of practical programming skills.

Abstract

The objective of this research is to map the unique tree species composing the vegetation in the tropical, sub-mountain, and mountain zones of Tambora National Park. This study is essential for the development of teaching materials, specifically eco-tourism-based science modules, which have been implemented in Tambora National Park. Data collection was carried out on four hiking trails: Kawinda Toi, Doro Ncanga, Piong (Kore), and Pancasila. The data collection techniques used namely plot transects and exploration methods. The results showed that in the tropical zone (1-1000 m asl), the dominant tree species were pato (Buchacania sessifolia) with an Importance Value Index (IVI) of 41.86%, monggo putih (Syzigium sp.) with an IVI of 34.00%, and monggo merah (Syzigium polyanthum) with an IVI of 33.80%. In the sub-mountain zone (1000-2000 m asl), the dominant species were cemara gunung (Casuarina junghuhniana) with an IVI of 44.50%, sarume ara (Acronychia trifoliata) with an IVI of 40.23%, sarou (Engelhardtia spicata) with an IVI of 40.19%, and kosok (Myrsine avenis) with an IVI of 38.75%. In the mountain zone (above 2000 m asl), the dominant species was cemara gunung (Casuarina junghuhniana) with an IVI of 300%. Endemic species identified included Elaeocarpus batudulangii (endemic to Nusa Tenggara) and Parachidendron pruinosum var. sumbawaense (endemic to Sumbawa Island). The populations and distribution of these endemic species are very limited. Other noteworthy species include klanggo (Duabanga moluccana), sori hitam (Syzigium acuminatissimum), and sori putih (Syzigium racemosum). The output of this research is a science module in the form of a Field Guide and booklet based on eco-tourism interpreting the unique forest trees for teaching ecosystem materials in secondary schools and as a guide for tourists, as well as providing information for the management of Tambora National Park in West Nusa Tenggara.

Abstract

This study aims to develop and test a mobile-app-based e-assessment oriented towards science literacy for prospective science teachers. The research and development (R&D) method with the 4D model was employed in this study. A multiple-choice test instrument with reasoning was developed to measure the science literacy skills of prospective science teachers. The instrument was validated by material experts and media experts to ensure its validity and reliability. The results showed that the developed mobile-app-based e-assessment is valid, reliable, and practical to use. Limited trials indicated that the application is effective in improving the science literacy of prospective science teachers. This research contributes to the development of innovative and effective technology-based assessment instruments to improve the quality of science education.

Abstract

This research is a continuation of previous research by the authors. The modified TOSRA (Test of Science-Related Attitudes), originally developed by Barry J. Fraser in 1987 for secondary high school students, has been validated in the previous research to be suitable for elementary school students in Mataram. This research aims to obtain an initial profile of science-related attitudes of grade 5 elementary school students in Mataram generally, based on gender and based on the school. This research aims to identify students’ science-related attitudes in four indicators: attitude to scientific inquiry, adoption of scientific attitudes, enjoyment of science lessons, and leisure interests in science. This descriptive ex post facto study explores the science-related attitudes of 318 students from 3 elementary schools in Mataram, Indonesia. The results revealed that there is a difference in indicator attitude to scientific inquiry. Still, there is no difference in the adoption of scientific attitudes, enjoyment of science lessons, and leisure interests in science between the students in these schools, and no significant differences in results based on gender overall.
