This research aims to increase the influence of the Problem-Based Learning model on students' critical thinking abilities in mechanical wave material. This quasi-experimental research uses a non-equivalent control group design. The research population included all students in class XI MIPA at one of the State High Schools in East Praya. Sampling used a purposive sampling technique so that 2 groups were obtained, namely 30 experimental class students and 30 control class students. The experimental class was given treatment in the form of using the Problem-Based Learning model, while the control class used the conventional model. Students' critical thinking abilities are obtained from the description questions they work on. Data from the pretest results of experimental class students obtained an average score of 25 and control class students obtained an average score of 23. The posttest scores showed that the critical thinking abilities of experimental class students were in the good category with an average score of 78.6 and the students in the control class were in the good category with an average score of 74.3. The research hypothesis was tested using the polled variance t-test at a significance level of 5%. Data analysis shows that the t<sub>count</sub> value, namely 3.384, is greater than t<sub>table</sub>, namely 2.002, which means that H<sub>0</sub> is rejected and H<sub>a</sub> is accepted, so it can be concluded that there is an influence of the Problem-Based Learning model on students' critical thinking abilities in mechanical wave material.</p> 2024-02-21T00:00:00+08:00 Copyright (c) 2024 Saadila Hayati, Gunawan, Hikmawati https://journals.balaipublikasi.id/index.php/amplitudo/article/view/137 Sources of Error in Blood Pressure Measurement Using Digital and Aneroid Tensimeters 2023-11-30T14:37:20+08:00 Muhammad Zuhdi mzuhdi@unram.ac.id Ahmad Busyairi mzuhdi@unram.ac.id <p>A tensimeter is an instrument works with concept of physics used to measure blood pressure. The measured blood pressure is the relative pressure between the pressure inside the blood vessels compared to the pressure of the atmosphere. Blood pressure measurements using a digital tensimeter are much more acurate than measurements using a aneroid tensimeter. Measurements with an aneroid sphygmomanometer at a hospital in the city of Mataram showed a measurement error up to 20 mmHg compared to a digital sphygmomanometer. Source of error consist of two main factors ie. Instrument error and human error. From this research it was found that measurements using a digital sphygmo-manometer are more accurate, so the use of this type of sphygmomanometer is highly recommended for clinical measurements in hospitals and health hospitals.</p> 2024-02-21T00:00:00+08:00 Copyright (c) 2024 Muhammad Zuhdi, Ahmad Busyairi https://journals.balaipublikasi.id/index.php/amplitudo/article/view/160 The Impact of Physics Modules Based on Problem Based Learning on The Problem-Solving Abilities of Students in the Material of Optical Instruments 2024-01-03T11:22:27+08:00 Erika Erika erika.eka2001@gmail.com Syahrial Syahrial syahrial.a@unram.ac.id Hikmawati Hikmawati hikmawati@unram.ac.id <p>The purpose of this study is to ascertain how students' problem-solving skills are affected by the use of a problem-based learning physics module. A nonequivalent control group design and a quasi-experimental research methodology are used. Test instruments in the form of descriptive questions and non-test instruments in the form of a questionnaire on student replies make up the instruments utilized. Students in grade XI at SMA Darul Falah for the academic year 2022–2023 make up the study population. Purposive sampling was used to choose the research sample, resulting in the experimental group consisting of 21 students from class XI MIPA 2 and the control group consisting of 21 students from class XI MIPA 1. For the experimental group, a customized problem-based learning module in physics was employed. The Problem-Solving Ability instrument consists of descriptive questions that have been tested for validity, reliability, difficulty level, and item discrimination. The experimental group's average post-test score was 83.66, compared to 60.09 for the control group. Both groups' data were uniformly distributed and homogeneous. The hypothesis test results indicated that the calculated t-value was greater than the critical t-value, specifically 6.33, which is higher than 2.02 for the post-test data. Therefore, the alternative hypothesis ( ) is accepted, and the null hypothesis ( ) is rejected, indicating an influence of using the physics module based on problem-based learning on students' problem-solving abilities in the topic of optical instruments. Based on the analysis of the questionnaire responses, students' responses improved after the implementation of the physics module based on problem-based learning, with an implementation percentage of 72%. In conclusion, there is an influence of using the physics module based on problem-based learning on students' problem-solving abilities in the topic of optical instruments.</p> 2024-02-21T00:00:00+08:00 Copyright (c) 2024 Erika, Susilawati, Syahrial, Hikmawati
