Abstract

Microplastics (MPs) have become an interesting topic of discussion especially after many studies reported their presence in aquatic ecosystems. Pollution by microplastic particles in aquatic systems is a critical issue the world that has the potential to damage aquatic ecosystems. Therefore, this study aims to identify the abundance and characteristics of MPs in water, sediment and seagrass in tourist areas. Samples were obtained from three location categories, first the port, second the hotel area and third the residential area located in the Gili Trawangan tourist area, Lombok, Indonesia. After optimization of extraction, characterization was carried out using a stereo microscope to identify MPs. The results show that the average abundance of MPs in the three location categories is, 13.25 ± 17.21; 19.25 ± 23.30; and 16.50 ± 18.52 particles/L at water, 22.00 ± 30.84; 20.00 ± 30.80; and 6.00 ± 8.49 particles/kg dry weight (dry weight) sediment, and 17.50 ± 15.69; 16.25 ± 22.56; and 8.25 ± 8.46 particles/individual at seaweed. Then from this abundance, the types of MPs were found in the form of fragments, fibers, films and pellets, where the dominant colors are black, yellow, blue, red and green, with the highest size < 500 µm. From this study it is necessary to see the impact of MPs on seaweed and the aquatic environment around Gili Trawangan.

Abstract

The development of ways to test the quantities of preservatives in beverages is required, since they are often included in these drinks. It is important to keep an eye on the amount of preservatives used in drinks since several research have shown that they may cause a variety of disorders. The researchers in this study set out to find out how much sodium benzoate and potassium sorbate were in various drinks sampled from the city of Medan. They also wanted to make sure their analytical approach was sound.This study used a reversed-phase HPLC technique using an Eclipse plus C18 column measuring 250 x 4.6 mm and 5 μm, a phosphate buffer mobile phase with a pH of 5, a 70:30 ratio of metanol, and a flow rate of 1.0 ml/minute. The linearity test passed with a coefficient of determination (R2) of 0.99998 - 0.99999, as shown in the method validation results. A range of 0.2541-0.31101 mg/kg was observed for the LOD values. There was an intermediate accuracy of 0.24% to 0.28%, a percent RSD of the repetability values ranging from 0.21% to 0.24%, and a LOQ from 0.8469 to 1,0338 mg/kg. An average of 99.95% to 104.52% recovery was the outcome. Beverage sweetener determination using the described approach has been a success.

Abstract

This study aimed to develop and evaluate a STEM (Science, Technology, Engineering, and Mathematics)-oriented physics instructional tool on sound waves to improve collaboration skills in an inclusive high school setting. Using the ADDIE model, the development process included need analysis, instructional design, expert validation, and limited classroom implementation. The product consists of a syllabus, lesson plans, a student module, worksheets, and assessment instruments tailored for diverse learners, including students with Special Educational Needs (SEN). Expert validation involving material, media, and instructional tool reviewers resulted in scores within the “very good” category (average >3.25). Classroom implementation involved 28 students, including one deaf student, who engaged in group-based activities. Student responses showed high acceptance (mean score = 0.74), particularly regarding contextual learning and fair task distribution. Observation using Brookhart’s collaboration rubric, showed medium-to-high improvement (average normalized gain = 0.67). Notably, the deaf student actively contributed to group tasks, highlighting the product’s inclusivity. These findings suggest that STEM-based instructional tools can effectively support collaborative learning in inclusive physics classrooms. The study recommends further large-scale implementation to validate impact on broader student populations.

Abstract

21st-century education demands critical thinking skills, which still need to be improved among Indonesian students, especially at the junior high school level. Substance matter and its changes have the potential to train critical thinking through analysis and real problem-solving but are often taught without in-depth understanding. Therefore, the development of problem-based questions is needed to measure and improve students' critical thinking skills. This research aims to develop a problem-based question instrument to measure students' critical thinking skills on substance topics and their changes. This type of research is research and development that involves modifying the Borg & Gall model. The instrument developed is in the form of 30 multiple-choice questions to determine the achievement of students' critical thinking skills. The questions developed are adjusted to critical thinking skills strategies, namely ((1) focus on questions; (2) analyze arguments; (3) ask and answer challenge clarification questions; (4) consider the credibility of a source; (5) observing and considering the results of observations; (6) making deductions and considering the results of deductions; (7) making induction and considering the results of induction; (8) making and evaluating decisions; (9) identifying assumptions; and (10) determining an action. The validation of evaluation experts, subject matter experts, and junior high school science teachers showed that problem-based questions were valid and feasible to measure students' critical thinking skills toward substance material and its transformation

Abstract

A study has been conducted to determine the Diagnostic Reference Level (DRL) in non-contrast and contrast chest CT scan examinations at Bali Mandara Hospital. The study was conducted at the Radiology Installation of Bali Mandara Hospital using dose reports from non-contrast and contrast chest CT Scan examinations with data obtained including age, gender, kV, mAs, slice thick, time rotation, Pitch, as patient information and protocols used in the examination and dose information in the form of CTDIvol and DLP. This study aims to determine the local DRL value against the national DRL value. The method used to determine the DRL value in this study is by collecting data in the form of recording and documenting the dose report of CT Scan examination patients, with the data for each examination being as many as 30. From the recorded data, the CTDIvol and DLP values are used to find the DRL value by sorting it from the smallest to the largest value and then calculating the 3rd quartile as a determinant of the local DRL. The interpolation method is also used to consider the position of the 3rd quartile so that it is at a decimal value. From the research results, the CTDIvol value for non-contrast thorax examination was 6.43 mGy, and the DLP value was 293.08 mGy.cm. Meanwhile, in contrast to the thorax examination, the CTDIvol value was 6.14 mGy, and the DLP value was 852.57 mGy.cm. Furthermore, a statistical analysis was carried out in the form of a one-way t-test using SPSS software, which was used to compare the DRL values of both CTDIvol and DLP non-contrast and contrast thorax examinations with the standard values set by BAPETEN 2021 as a reference used in Indonesia. Based on the results of the analysis with a one-way t-test, it can be seen that the DRL values for non-contrast thorax examinations (DRL CTDIvol and DLP) and contrast examinations (DRL CTDIvol) do not exceed the standards set by BAPETEN. However, in the contrast thorax CT Scan examination, the DRL DLP value exceeded the standard value set by BAPETEN, so dose optimization was needed by re-evaluating the protocol implemented at Bali Mandara Hospital.

Abstract

This study investigates the effect of a STEM (Science, Technology, Engineering, and Mathematics) approach integrated with the flipped classroom model on students’ critical thinking skills in physics learning. Using a quasi-experimental method with a nonequivalent control group design, data were collected through pretests and posttests using validated and reliable essay tests. The sample consisted of students selected through purposive sampling from two senior high schools. Results indicate a significant improvement in the critical thinking skills of students in the experimental group compared to the control group, based on N-gain and independent t-test analyses. Notably, improvements were observed in inference and explanation indicators. These findings suggest that integrating STEM with the flipped classroom model can effectively enhance students’ critical thinking in physics education. This shows that students with a STEM approach have better abilities to solve problems, draw conclusions, and explain ideas.

Abstract

The high rate of malnutrition in Indonesia, especially stunting in children, is caused by economic constraints, lack of nutrition education, and limited access to health services, which have an impact on children's growth, cognitive development, and academic achievement. The success of primary school nutrition improvement programs is influenced by factors such as community involvement, policy support, and parents' and teachers' understanding of nutrition, although they still face implementation challenges that need to be overcome for long-term effectiveness. This research method uses a quantitative approach with surveys and statistical analysis to examine the factors that affect the success of the nutrition improvement program in grade 1 elementary school students in three schools in Purworejo District. With 106 respondents, data were analyzed using Pearson correlation, and linear regression through SPSS 27. The results of the t-test showed that the factors that affect the success of the nutrition improvement program have a significant influence on the success of the program (t count = 5.164; Sig. = 0.000 < 0.05). In addition, the results of the F test (F count = 26.666; Sig. = 0.000) confirmed that the regression model used was statistically significant so that the independent variables together affected the success of the program. The success of school nutrition programs relies on collaboration between parents, teachers, schools, and the government to improve nutritional knowledge and food availability. Policy support, including healthy food subsidies and training, is essential for ensuring the program's long-term sustainability.
