Abstract

This study aims to improve students' understanding of sound wave material through the application of guided context- and problem-based learning (GC-PBL) models. The method used was a quasi-experimental design with a non-randomized control group pretest-posttest design. The sample in this study was class XI MIPA, which consisted of two classes, namely class XI MIPA 3 as the GC-PBL class and class XI MIPA 2 as class C-PBL. The instrument used is a comprehension ability test. The results obtained showed that students in the GC-PBL class experienced an increase in the high category, while students in the C-PBL class experienced an increase in the medium category. Differences in the increase in understanding ability were then tested statistically and showed that there were significant differences. The implications and recommendations in this study are discussed.

Abstract

This study aims to visualize the temperature distribution on metal plates by solving elliptic differential equations using the help of the Microsoft Excel program. Many physics problems have limited analytic solutions so a numerical solution is needed. One of them is about the temperature distribution on a homogeneous metal plate in a steady-state conditionThe equation of heat flow in steady-state conditions is an elliptic partial differential equation (PDE). By solving this equation, we will have a numerical model of the plate that can be a mesh with a certain temperature point. Each point has been known to calculate the temperature value. The temperature value influenced. The Temperature value influenced borders on the plate and the presence of heat generation. The edge of the plate can be a constant temperature, a convection zone with the outside air, or an isolated edge. This model is then processed using Microsoft Excel with the iteration calculation until the temperature distribution value is obtained. The results obtained a graphical visualization of temperature distribution on the plate.

Abstract

E-books are essential in developing 4C skills and differentiated learning because they offer accessibility and flexibility that support students' diverse learning styles. In addition, they allow customization of teaching materials according to students' needs, which increases motivation and learning independence. This research aims to develop an e-book based on 4C skills through a differentiated approach to valid, practical science learning. This study falls within the development research category that uses the ADDIE model. With an average validation score of 3.73, this e-book falls into the “very valid” category. In practical terms, this media is easy for teachers and students to use, fits the learning plan, and shows a learning implementation rate of 90%. Student responses were very good, with an average of 89.79% for four evaluation indicators, showing great benefits and a high level of satisfaction in the learning process. Overall, the e-book based on 4C developed through a differentiated approach to science learning can be categorized as valid and practical because it can increase student involvement in learning. In addition, interactive features in e-books support communication and collaboration between students, allowing them to share ideas and opinions. E-books also enable teachers to adapt material to individual needs so each student can learn at the pace and style they desire.

Abstract

Matrix Laboratory (MATLAB) is a software based on matrices, which is easy to use for solving various mathematical and computing problems. This study aimed to determine how variations in tube current (mA) affect the radiographic image of the cranium using the MATLAB program and to assess the program's quantification of this effect. The sample in this study consisted of 3 volunteers who performed AP projection cranial radiography examinations with varying tube current at Pelamonia TK. II Hospital, Makassar. Each sample had the same treatment in patient preparation, examination position, examination projection, and the same exposure factor value, which differed only in the use of tube current values, ​​where the volunteer 1 with 200 mA, the volunteer 2 with 250 mA and volunteer 3 with 320 mA. Measurement of the quality of the AP projection cranium image with tube current of 200 mA, the percentage was 96.11%. At 250 mA, the percentage was 95.00%; at 320 mA, it dropped to 92.78%. It was determined that the optimal tube current variation was 200 mA with the highest percentage in measuring the image quality (density, contrast, sharpness, and detail) of the AP projection Cranium against variations in tube current is almost perfect.
