<![CDATA[The 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. The same thing for learning outcomes of physics students also increased from cycle I to cycle II, with the average results obtained very good category. Thus the implementation of the Meaningful Instructionnal Design (MID) model is effective in increasing interest and learning outcomes of students of class XI MIPA4 SMA Negeri 1 Pekanbaru, in learning fluid material.]]>

<![CDATA[In general, this research aims to produce a valid magnetic induction experimental device as a medium for learning physics in high school. The experimental device consists of experimental equipment and tool usage manual. In particular, this research aims to design, build, and validate devices for magnetic induction experiments on coiled wire as a physics learning media according to the research development steps. Three experts and two physics teachers as users have been involved to provide an assessment of the experimental devices that have been built. Assessment is carried out on the construction and content of the experimental device. The results of data analysis showed that every aspect of the assessment of the experimental tool was declared valid with a very good category (index validity 3.34) and the manual for using experimental tools was also declared valid with a very good category (index of validity 3.47). Thus, it can be said that the magnetic induction experimental device in circular wire is declared valid as a medium for physics learning.]]>

<![CDATA[Accommodating the latest learning challenges that require online learning support, a flipped classroom blog learning media that is valid has been produced, but has not been used in class, to see its effectiveness.Therefore the purpose of this research is to describe the cognitive learning outcomes of class X students of SMA Negeri 5 Pekanbaru, through the application of classroom flipped blog learning media on work and energy material. The research method used is Pre-Experimental desgn. The research subjects were class X students of SMA Negeri 5 Pekanbaru which numbered 36 students. Research data are online quiz data and cognitive learning outcomes from post-test scores after the use of flipped classroom blog learning media. Data were analyzed descriptively to see the level of absorption of students' cognitive learning outcomes. The results of the online quiz data analysis through the flipped classroom blog found that the overall absorption of the online quiz was 85.92% with a very good category. The results of the post-test data analysis of learning outcomes obtained an average absorptive of 81.80%, with a good average absorptive category. The effectiveness of learning based on the absorptive score of the class average includes the effective category. So that the learning media of flipped classroom blogs as innovative learning media that are effectively used in learning work and energy material in class X SMA Negeri 5 Pekanbaru.]]>

<![CDATA[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.]]>

<![CDATA[Bunut is one of regions in Kisaran. The majority of Asahan District work as shoe craftsmen. The length time of shoes making procces make the shoe craftsmen need long time to market it. Similarly when designing shoe model that still us traditional tools that make shoe’s model impressed outdated. In terms of making Bunut shoe is not easy. Cutting leather shoe that use traditional tools make the cutting process of the shoe becomes long. The method is started from designing a modeling tool, preparing tools and material, making and testing machines. The result obtained by this shoe modeling machine work optimally 8 hours per day with the cutting velocity 1,4 minutes for each shoe's pattern, from the result modelling machine able to cut design pattern a pair of shoes in 40 minutes. So in one day it can produce shoe pattern pieces is able to produce 12 pairs of shoe patterns from the previous one, only 2 pairs per day.]]>

<![CDATA[Science literacy is the capacity of individuals to use scientific knowledge to be able to make the right decisions related to nature and human interaction. This study aims to produce test instruments based on scientific literacy on energy matter in living systems. The research method used is Research and Development (R & D) using the ADDIE (Analysis-Design-Development-Implemtation-Evaluation) development model. The stages of the study began with an analysis of the problems of science literacy skills of Indonesian students, then proceeded to develop indicators of questions based on the PISA 2015 indicators. After the indicators were developed, they were followed by making questions and question validation by 3 expert validators. Questions that have been validity tested are limited to 31 students. Data obtained from logical validity and limited trials. Then the data is analyzed descriptively. The results of the analysis of the data obtained are, the validation assessment of science literacy-based test instruments on energy material in living systems by experts is 79.39% with valid validity levels, while the assessment of limited trials is obtained from the validity of 17 questions declared valid and have value reliability of 0.6 with moderate reliability.]]>

<![CDATA[The implementation of learning, especially Physics, is currently based on the results of observations still experiencing several obstacles. The tendency of passive students and learning outcomes as part of students still shows results that have not been maximal. Based on this fact, this classroom action research was carried out to improve the learning process and physics learning outcomes of students in the fluid material in class XI IPA1 SMA 4 Pekanbaru, using PHET (Physics Education Technology) media. The type of research conducted is classroom action research consisting of 2 cycles, with the subject are students of class XI SMA Negeri 4 Pekanbaru. Time for the implementation of odd semester 2018/2019 academic year. Data collection techniques used observation sheet instruments for learning activities and fluid material test sheets for physics learning outcomes. Data is analyzed descriptively in percentage representation. The results of the research showed that the learning activities of students had increased from cycle I to cycle II. Furthermore, for physics learning outcomes, students increase from the first cycle to cycle II, with the average results obtained by the good category. Therefore, the application of PHET-based information technology simulation media in physics learning can improve learning activeness and learning outcomes of class XI students of SMA 4 Pekanbaru.]]>
