Abstract

This research was aimed to produce students worksheet (LKPD) based on PhET Interactive Simulations Software in cognitive through the application of physics-based guided discovery learning model that is devoted to the concept of Newton's Law of Motion. Guided Discovery-based approach is expected and is believed to develop students' skills in various aspects of one study that showed achievement levels mastery of physics students after participating in the learning process under the expected educational purposes. Researchers conducted a study on the process of learning physics for the discovery-oriented at vocational senior high school students in Newton's law of motion with R&D. Subjects were students of class X TKRO in the first semester of the academic year 2018-2019 in vocational high school in Ciamis, West Java Province as many as 35 students. Data collected through tests, observations and interviews.

Abstract

Abstrak- The study about fill factor and efficiency solar cell have been done with an automatic drive machine that rotates the surface of the solar cell following the movement of the light source from 0° up to 90° compared without automatic drive.  The test results are then implemented to determine the fill factor and efficiency in variations in light intensity. In this study, polycrystalline solar cell type (99 × 69) mm2, the Philips 100W/220V light bulb at a distance of 18 cm and the driving machine is controlled through an Arduino Uno R3 microcontroller. Data acquisition of current and voltage is carried out with the help of DCP-BTA current and VP-BTA voltage probes that are connected to the mini labquest transducer and displayed to a computer through loggerpro software. The result show that it has been successfully designed an automatic driver of a solar panel (99 × 69) mm2  with an Arduino Uno R3 microcontroller and a logger pro software as data acquisition software. The using solar cell automatically driven can improve the accuracy and precision of current and voltage readings so the fill factor might be increased up to 10% while the efficiency of solar cells does not change. Variations in light intensity can increase the fill factor and efficiency of solar cells. Fill factor and efficiency have an exponentially relationship to light intensity.

Abstract

The magnitude of the damping force of the mathematical pendulum swinging on a medium is usually proportional to the speed of the pendulum. In this research, the pendulum oscillation parameters oscillating on an air medium under the influence of a magnetic field of 1.8 G will be investigated. In the initial stage, the effect of the magnetic force on the damping coefficient of ferrite pendulum oscillations with an initial deviation of 15 degrees observed. Furthermore, the study continued with varying the angle of deviation from 5 degrees to 25 degrees. The results of the data fitting amplitude (xi) at various swing times (ti) are using to analyze the effect of the angle of deviation on the maximum amplitude. The results showed that for the deviation angle of 15o the coefficient of damping of the medium affected by the magnetic force was 0,0022 greater than the coefficient of air damping 0,00006. It affects the amplitude, which decreases faster than the pendulum amplitude without the influence of magnetic force. Variation in the angle of deviation also affects the amplitude of the pendulum. In the deviation angle below 10, the pendulum motion is more influenced by the magnetic force, whereas in the deviation above 10, the pendulum motion is more dominated by gravity.

Abstract

This research aims to develop teaching materials for project-based learning models for science, technology, engineering, and mathematics (STEM). The procedure for developing teaching materials refers to the 4D model (Design, Define, Develop, Disseminate). The research instrument was in the form of teaching material validation sheets and science process skills tests. The design used is a non-equivalent (pretest-posttest) design. Data were analyzed using due diligence and effectiveness analysis. The product, as a result of the development, was tested and involved two covariates: initial ability and scientific attitude. The developed teaching materials have a very valid category, and the feasibility value of the science process skills test questions from the validator is 97% very good category. The resulting product is practical to apply based on the results of learning management. PjBL STEM teaching materials can improve science process skills.

Abstract

Penelitian ini bertujuan untuk menerapkan Reciprocal Teaching berbantuan Google Sites untuk meningkatkan keterampilan komunikasi sains siswa.  Penelitian ini dilakukan dengan menggunakan metode penelitian tindakan kelas model Kemmis dan MC Taggart yang terdiri dari dua siklus. Paradigma ini dimulai dengan perencanaan, kemudian tindakan, kemudian observasi, dan akhirnya kegiatan refleksi. Penelitian dilaksanakan pada 26 siswa di kelas VIII SMP Negeri 3 Satu Atap Borobudur. Dalam penelitian ini nilai KKM adalah 65. Sedangkan tingkat keaktifan siswa minimal sedang (33%-66%). Sementara keterampilan komunikasi sains siswa cukup (66%-75%). Hasil penelitian menunjukkan bahwa pembelajaran IPA dengan menggunakan Reciprocal Teaching berbantuan Google Sites dapat meningkatkan keaktifan guru pada kategori baik (94%) dan keaktifan siswa meningkat dari kategori sedang menjadi baik (71%), ketuntasan belajar siswa mencapai ketuntasan klasikal pada Siklus II (77%) dan keterampilan komunikasi sains siswa meningkat dari kategori cukup menjadi baik secara signifikan (79%), sehingga penggunaan Reciprocal Teaching berbantuan Google Sites untuk meningkatkan keterampilan sains siswa SMP berhasil.

Abstract

Pembelajaran fisika seringkali mengharuskan guru untuk menciptakan suasana belajar yang dapat menumbuhkan motivasi siswa. Seringkali siswa merasa bahwa fisika merupakan mata pelajaranyang sulit sehingga membuat siswa menjadi malas untuk mulai belajar. Ditambah dengan metode pembelajaran yang itu – itu saja yaitu guru menerangkan didepan, memberikan contoh soal lalu siswa diminta untuk mengerjakan soal. Mengakibatkan siswa merasa bosan sehingga penerapan teknologi dalam pendidikan dapat diterapkan agar pembelajaran dapat berjalan yang efektif dan menyenangkan serta dapat membangun motivasi siswa untuk belajar. Salah satu model pembelajaran yang dapat meningkatkan motivasi belajar siswa adalah game based learning sehingga penelitian ini bertujuan untuk mengetahui pengaruh penerapan game based learning menggunakan kahoot terhadap motivasi belajar fisika. Penelitian ini merupakan penelitian kuantitatif deskriptif model one group design. Dengan dua kali penyebaran angket motivasi belajar angket tersebut adalah angket pre-test dan post-test. Penelitian ini dilaksanakan di MA Muhammadiyah Watulimo pada kelas X materi hakikat fisika. Hasil dari penelitian ini sebelum penerapan model game based learning menggunakan kahoot indikator motivasi belajarnya hanya sebesar 55%, setelah penerapan 88%, kesimpulan dari penelitian ini adalah model game based learning menggunakan kahoot dapat mempengaruhi motivasi belajar siswa.
