Abstract

In this study, Fluxgate made with a design 30 and 20 winding excitation coil pickups. Fluxgate used to measure vibrations in two dimensions. Vibration measurements performed indirectly by using two mechanical pendulum to vibrate in the direction of axis x and y are placed on the source of vibration. Fluxgate sensor working principle is developed when there is vibration, then the magnetic mass at the end of the pendulum arm will come to move in rhythm with the vibration. This will result in the distance between the sensor with a magnetic mass changes. Changes in this distance will lead to changes in magnetic induction at the core of the sensor. Because of the large magnetic field intensity received by the sensor varies with the distance the vibration amplitude changes that occur will result in a change in voltage generated by the sensor. This means that the emf is happening is a function of the distance between the sensor with a magnetic mass. Fluxgate sensor is placed in the direction of axis x and y. Based on analysis of data obtained sensitivity of the sensor x and y with the same value that is ± 39 mV / μT. The range of frequencies that can be detected by sensors in this study were 0.37 Hz to 1.81 Hz and amplitude range that has been carried out ranging between 0.7 cm to 2.3 cm. Maximum absolute error and maximum relative error in the characterization of the frequency obtained is happening on the sensor y of 0.054 Hz and -2.18%. For amplitude obtained is happening on the sensor x 0,005 volt and 3,28%.

Abstract

This research is motivated by the use of cognitive assessment instruments on daily and mid-semester tests on learning class X physics used in the form of questions that tend to test more aspects of memory, understanding and application. While questions that test aspects of analysis, evaluation and creation are not widely available. In the matter of Newton's law, most students still experience difficulties in solving problems related to Newton's law. In fact, the questions on Newton's law are related to the application of technology in everyday life. To overcome these problems the students need to be directed to develop high-level thinking skills. Therefore, one way to improve students' high-level thinking skills by carrying out HOTS-based evaluations. In line with these problems it is necessary to feel it. Development of Higher Order Thinking Skills (HOTS) Assessment Instruments in Physics Learning in Newton's Legal Material Class X SMA / MA. The purpose of this study is to produce Higher Order Thinking Skills (HOTS) Assessment Instruments in Physics Learning in Newton's Law Material of Class X SMA / MA which is valid, practical and effective

Abstract

This research is motivated by the low ability of scientific literacy of students. One of the causes of students 'low scientific literacy skills is the lack of teaching materials that can shape students' scientific literacy skills. The available teaching materials have limitations to illustrate the facts of the lessons learned in everyday life. The type of research used is research and development with the ADDIE design model (Analysis, Design, Development, Implementation, Evaluate). Based on research and analysis of CTL-based e-module data using Kvisoft Flipbook Maker on the ability of scientific literacy, namely: obtain an average value of 4 people validator 88% with a very valid category. practicality assessment of 2 physics educators was 79.33% with a practical category. Practical assessment of 15 students received an average value of 90.26% in the category of very practical, has an average value of 84.79% with a very practical category. Assessment of the effectiveness of scientific literacy of 15 students for e-learning modules in the questionnaire obtained an average value of 88.78% with a very effective category while the test questions on the kinetic theory of gas with 66.6% completeness and in the material thermodynamics with 64.8% completeness with an average value of 65.7%. So it can be concluded that e-module based on Contextual Teaching And Learning (CTL) using Kvisoft Flipbook Maker on the kinetic theory of gas and thermodynamics is very valid, practical and effective to improve science literacy in physics learning class XI MIPA 6 SMA N 15 Padang

Abstract

The development of science and technology has had a major influence in all aspects of life, including in the world of education. One way of using technology in learning is the use of technological resources in the learning process such as technology-based interactive modules.The use of modules in learning aims so that students can learn independently without or with guidance from educators, so that students will learn better if they do it alone which focuses directly on mastering learning objectives. The aim of this research is to produceInteractive module based on Trait Treatment Interaction (TTI) using Adobe Flash on collaboration  skills with students on the material of the kinetic theory of gases and the laws of thermodynamics class XI SMA / MA valid, practical and effective. This research is a research and development (R&D). Development design is using a development model ADDIE consists of: the Analysis stage (analyzing), the Design stage (designing), the Development stage (developing), the Implementation stage (implementing) and the Evaluation stage (evaluating). The instruments used in this study were a validity questionnaire, a practicality questionnaire, and an effectiveness test. The product validity test is given by expert validators in the aspects of material / content, media / construction, and language. The practicality test is given  to educators and students, while the effectiveness test is given to students. The results of the research were produced Interactive module based on Trait Treatment Interaction (TTI) using Adobe Flash for students on the material of the kinetic theory of gases and the laws of thermodynamics which is very valid, very practical and very effective against collaboration skills of students.

Abstract

Telah berhasil dilakukan sintesis lapisan tipis magnetite (Fe3O4) pada substrat Indium Tin Oxide (ITO) dengan metode Elektrodeposisi (ED), menggunakan arus Continue Direct Current (CDC), dengan variasi tegangan eksternal. Variasi tegangan eksternal ini dilakukan untuk mengetahui kondisi optimum penumbuhan lapisan tipis yang akan dilakukan. Tegangan eksternal yang diterapkan mula-mula dengan range yang lebih besar yaitu 10 volt, 5 volt, dan 3 volt. Berdasarkan pencitraan dengan mikroskop tegangan 3 Volt dipilih sebagai kondisi mula-mula untuk variasi berikutnya yaitu variasi dengan range tegangan yang lebih kecil (3,5 volt, 3 volt, dan 2,5 volt) dan dari ketiga variasi tersebut tegangan 3,5 volt dipilih sebagai tegangan optimum untuk proses sintesis lapisan tipis magnetite (Fe3O4). Hasil pencitraan dengan mikroskop optik menunjukkan bahwa tegangan ikut mempengaruhi ketebalan hasil deposisi. Dengan kata lain dapat disimpulkan nilai tegangan ekternal yang diaplikasikan sangat mempengaruhi hasil deposisi dengan korelasi bahwa semakin besar tegangannya, makin tebal hasil deposisi dan sebaliknya semakin kecil tegangan semakin tipis hasil deposisi di atas substrat.
