Abstract

Fluids are substances that can flow. One of the flow substances is liquid. Every liquid has a characteristic that distinguishes a liquid from another liquid. One characteristic of a liquid is viscosity (thickness). The measuring instrument used to determine the viscosity of a liquid is a viscometer. Due to the importance of the amount of viscosity, so it is necessary to know the measurement easily, cheaply, and thoroughly. One method is to use a stirrer viscometer as a liquid viscous measurement devices. The purpose of this research was to determine the construction and test the designed stirrer viscometer. The research method used is the experimental method. The procedure of this research includes designing, assembling, and testing a stirring viscometer. The results of experiments that have been carried out show that the stirrer viscometer devices can to used to measure the viscosity of liquids with time and temperature indicators. This tool effectively proves that the temperature affects the viscosity of a liquid where the higher the temperature of the liquid, the lower the value of the viscosity of the liquid, and conversely the lower the temperature of the liquid, the higher the viscosity value of the liquid.

Abstract

This research is a classroom action research that aims to improve student learning outcomes by using integrated multimedia learning physics for senior high school or equivalent. This research was conducted at the senior high school (SMA)12 Pekanbaru. The subjects in this study were students of class X IPA 1 with 36 students consisting of 16 male students and 20 female students. The study was conducted in two cycles and consisted of 8 meetings with the details of the first cycle consisting of three meetings and three times quiz and one daily test (UH) and the second cycle consisted of four meetings consisting of three meetings and three times a and one dayly test. Each cycle is analyzed and feedback and repairs are needed. Based on the results of the study, it was found that there was an increase in individual completeness in the 1st cycle. 40.41% at quis-1, 51.65% at quis-2 and 90.81% at quis-3. Likewise, the second cycle. 80.25 in quiz-1, 85.75% in quis-2 and 90.00% in quis-3. Based on these results it was found that the increase in individual completeness in the 2nd cycle was higher and more stable. This shows that the results of individual completeness during learning both cycle-1 and cycle-2 have increased, but the increase in cycle-2 is more linear. These results indicate that learning using integrated multimedia can improve student physics learning outcomes.

Abstract

West Sumatera is a disaster prone area, especially disasters such as earthquakes, landslides, floods, tsunamis, and volcanoes. The high potential of natural disasters has consequences for the importance of disaster mitigation efforts. School is an effective tool in shaping of mindset and behavior of students. One effort that can be done is integrate the topic of natural disaster into learning, especially physics learning. Integrating physical matter in learning requires material analysis aimed at making disaster topics integrated in accordance with learning topic. The type of this research is descriptive research. The results of the research indicate that an analysis of the relevance of learning material to the topic of integrated disasters needs to be done so that the integration between teaching material and the topic of disasters is carried out in harmony. Almost all physics learning material can be integrated with the topic of disasters that often hit the West Sumatra region. The classification of material on the topic of integrated disasters is classified into fact and metacognitive material.

Abstract

This study aims to measure the practicality of physics constructivist modules in the dynamics of rotation and rigid body balance using ADDIE’s model. The module practicality stages are: preparation, research introduction, practicality testing, filling out questionnaires, analyzing and conclusions, revising, and practical. There are 25 students and one physics teacher who asked using a questionnaire with 5 practical indicators, namely: efficiency, presentation of module material, ease of use, conformity with science, and implementation of constructive elements. The results of module practicality testing data analysis showed that the module efficiency level was 65.83 with the practical category, the module presentation rate was 90.16 with a very practical category, the module's ease of use was 86.08 with a very practical category, the degree of conformity with the science was 95,0 with a very practical category, and the level of implementation of constructive elements is 88.8 with a very practical category. Overall, the practicality of constructivist physics learning modules is 85.17 with a very practical category. Based on the results, it can be concluded that the constructivist physics learning module of rotational dynamics and rigid body balance is declared practical to be used as a source of learning for high school physics students.

Abstract

Physics learning for fluids can be done by practical methodes in orther the students really understand about the fluids concepts. One of the fluids learning that needs to be practice is about viscosity. Measuring instrument used to determine the viscosity of a liquid is a viscometer. This viscosity measuring instrument can measure the thickness of a fluids accurately and specifically in accordance with predetermined standards. Due to the importance of the amount of viscosity, it is necessary to know the measurement method easily, cheaply and thoroughly. One way that can be used is to use an alternative viscometer as a measure of fluids viscosity. The purpose of this research is to produce an alternative viscometer that can measure the viscosity of a fluids. The type of this research is research and development, namely developing and measuring with an alternative viscometer. This research results that the measurement with an alternative viscometer for several liquids with different viscosity, gets a value that is not much different from the standard viscosity measurement results. The conclusion of the results of this research is that an alternative viscometer can be used to determine the viscosity of a liquid.

Abstract

he purpose of this action research is to increase the interest and learning outcomes of physics students with the implemention of the Meaningful Instructional Design Model (MID). The influence of internal factors experienced by students in learning physics include difficulties in understanding the material and solving the questions correctly, so that students' learning interest is low. Meaningful Instructionnal Design Model includes a learning model that prioritizes learning meaningfulness, which should be able to increase students' interest and learning outcomes. This research is a classroom action research conducted in two cycles. The subjects of this study were students of class XI MIPA4, SMA Negeri 1 Pekanbaru. The research instrument used observation sheets for interest and test sheets for physics learning outcomes in fluid material. Data is analyzed descriptively in percentage representation. The results of the research obtained the interest of students in physics learning, experiencing an increase from cycle I to cycle II.
