Abstract

This study aims to determine the improvement of conceptual understanding of physics of class VIII students of SMP Negeri 40 Pekanbaru on the topic of light and optical through learning with cognitive conflict approaches. The type of this research is quasi experiment with population of 172 students of class VIII SMP Negeri 40 Pekanbaru consisted of 4 classes. Two classes were selected to be a research sample based on normality and homogeneity tests on repetition of sound material to obtain experimental and control classes, each of 43 people. The data collected by giving the physics’ conceptual understanding test in Bloom's taxonomy in the form of two tier multiple choice with 14 items. This instrument consists of 7 indicators of conceptual understanding, namely: interpretation, modeling, classifying, summarizing, drawing inference, comparing, and explaining. The result of the research showed that the ability of studens’ concept understanding after the application of learning with cognitive conflict approach was in the good category. The average score of the students’ understanding of the physics concept on the experimental group was higer than the average score of the control group. it can be concluded that learning with cognitive conflict approach can improve conceptual understanding of physics of class VIII SMP Negeri 40 Pekanbaru student on the topic of light and optics.

Abstract

Andaliman has the Latin name Zanthoxylum acanthopodium and is a family of Rutaceae. Andaliman is a native spice from North Sumatra called the golden spicy from North Sumatra. Andaliman farmers in Parsoburan Village, Toba Samosir said that one of the problems in andaliman production is the number of Andaliman fruits that are still not effective, even most of the Andaliman fruit becomes rotten. The design of Andaliman perfume machine has been carried out which aims to increase the usefulness of Andaliman through the manufacture of andaliman perfume as well as to increase the economic value of Andaliman. The method used is by designing a perfume machine and making an official perfume machine, testing the machine and using a perfume machine. Making perfume machines and testing perfume machines was carried out at the UNIMED Mechanical Engineering Workshop and the implementation of machine use activities was carried out in Parsoburan, Toba Samosir Regency. The results obtained from the andaliman smoothing machine were processed as 2 kg of perfume in a single smoothing process, for the heating stage mixed with 300 mL ethanol and the results of the perfume ± 20 mL which will be mixed with alcohol according to the strong aroma made.

Abstract

This research aimed to design wave visualization based VBA on microsoft excel as a valid physics learning media for senior high school students of class XI. This research used Research and Development method with ADDIE type. The steps of the design of learning media of this wave visualization include Analysis, Design, Development, Implementation, and Evaluation. However, in this research the researchers only implement up to the development step, then conducted media validation using assessment instruments. The instrument used is validation sheets of the wave visualization learning media. assessment is done on three aspects, namely design aspect, learning content aspect, and pedagogic aspect assessed by validator. Validator consists of team experts and users. Expert validator is a lecturer of Physics Education University of Riau, while the user is a teachers from senior high school on pekanbaru. The validation score obtained for the design aspect of the experts and users is 3.62. The validation score on aspects of learning content from the experts and users is 3.60 and the validation score obtained on the pedagogic aspect of the experts and users  is 3.73. The validation results of  wave visualization based VBA on excel is in the  category very high for all aspects assessed, thus this media can be valid and feasible to be used as a valid physics learning media of students class XI in senior high school.

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

This research aim to find the differences between the results of learning psychomotor skills ofphysics students to the concept of straight-line motion in the X class students MA Dar El Hikmahpekabaru between cooperative learning Think-Pair-Square and Two Stay Two Stray. This researchis the research study design experiments with the Posttest-Only Control Design. XB1-class researchsample as a class experiment I with the application of cooperative learning model Think-Pair-Square and class XB2 as a class experiment II with the application of cooperative learning TwoStay Two Sstray. Instrument data collection in this research are to learn psychomotor test resultsare analyzed by descriptive analysis and inferential analysis. Deskritif analysis obtained from theexperimental class I absorption average is 84.6% of students with a good category, exhaustivenessclassical learning students with 87.5% complete and exhaustiveness category subject matter is100% with complete categories. In the experimental class II absorption average is 85.9% ofstudents with a good category, effektiveness lesson is 85.9% with effective category, theexhaustiveness of students to study classical category of 91.6% with complete and completeness oflearning material is 100% by category thoroughly. With inferential after the data obtained arenormally distributed and homogeneous through the test for normality and homogenity test resultsobtained that the hypothetical accept, so there is no difference significan on student learningoutcomes through learning model Think-Pair-Square and Two Stay Two Stray. This can be seenthrough the t test was called t calculated <t table or 0.515 <1.679 by SPSS version 16.
