This research is the result of a multi-year research since 2013-2015, which aims to determine the shifting of learning environment associated with the development of mobile technology. The rapid changing on information technology has affected the current learning strategy. The analysis of this study is a qualitative descriptive approach. The result indicates that mobile technology shifted the tendency of students to learn in a more personalised way. This situation encourages teachers to be able to choose and use technology for students learning success. The implication of this research is that the teachers, students and schools will need to have a different role than before to adapt the changing in today's learning environment. More focus again, learning design needs to enable cooperative learning in a mobile for the convenience of studying individually. In the implication of this research, there is a shifting of learning environment due to mobile technology.
The ability to solve physics problems is still relatively low. Students more often directly use mathematical equations without performing concept understanding analysis. Therefore, learning strategies and media are suitable for physics learning. The purpose of this research is to develop interactive animated videos combined with flipped classroom learning models. This research uses Research and Development (R and D) methods, with 4D development models. The average validation test results are 90,91%, with a good category. So, the animation physics video can use in a flipped classroom. This physics animation video makes it easier for students to learn temperature materials and their changes without being limited by space and time. These physics learning animation videos are highly interactive and can explain abstract physics concepts and integrate with flipped classrooms.
AbstrakPenelitian ini bertujuan untuk memanfaatkan probabilitas distribusi Gaussian untuk membantu menentukan kualitas rangkaian penyearah gelombang penuh. Sebagai sampel digunakan dioda IN4002 dan IN4007 yang dihubungkan secara seri dengan tahanan 1.200 ohm. Rangkain dipasok dengan power supply 15 volt AC berfrekuensi 50 Hz. Data tegangan output diode dicuplik dengan bantuan sensor tegangan loggerpro pada setiap 5 detik sampai diperoleh 5000 data. Pengolahan data dilakukan dengan melakukan fitting data menurut distribusi probabilitas normal Gaussian. Kualitas penyearah ditentukan dari nilai simpangan baku yang kecil. Dari penelitian menunjukkan bahwa dioda 1N4002 mempunyai kualitas lebih baik sebagai komponen penyerah gelombang penuh dengan simpangan baku 0,39 %. Selain itu dari eksperimen ini dapat dihasilkan buku petunjuk praktikum yang layak digunakan untuk praktikum mahasiswa.Kata-kata kunci: kualitas penyearah gelombang penuh, dioda, distribusi normal Gaussian. AbstractThe objective of the research is employing Gaussian Distribution Probability to assist determination of quality of full wave rectifier circuit. Two diodes 1N4002 and 1N4007 were used as samples. The diodes were connected to resistor 1,200 ohm. The device was connected to 15 volt AC power supply with frequency of 15 Hz. Data were logged from diodes using loggerpro voltage sensor on each of 5 seconds up to 5000 data. Data was analyzed by fitting according to the Gaussian normal probability. The quality of device was determined from the lowest deviation standard. From the results show that diode 1N4002 have the best quality as an electronic component of full wave rectifier that have standard deviation of 0.39. Furthermore, from this research could be resulted a module of experiment that reliable if it is used as guidance book for experiment of students.
Abstrak. Telah dilakukan studi analisis content buku ajar termodinamika dengan tujuan untuk mengetahui kebutuhan penggunaan modul berbasis Technological Pedagogical And Content Knowledge (TPACK) pada mata kuliah termodinamika. TPACK merupakan pengetahuan yang menggabungkan hubungan antara teknologi, pedagogik, dan konten secara sinergis. Metode penelitian ini adalah deskriptif kualitatif. Penelitian ini untuk menganalisis isi dari buku-buku referensi yang digunakan dalam pembelajaran. Teknik pengumpulan data menggunakan observasi dan angket. Hasil analisis kandungan TPACK pada buku ajar I, buku ajar II, buku ajar III masing-masing didapatkan prosentase sebesar 15,38%, 20%, dan 28,57%. Hasil angket pada responden sebanyak 23 mahasiswa pendidikan fisika menyatakan bahwa 87% mahasiswa menyatakan perlunya dikembangkan modul termodinamika berbasis TPACK yang mendukung pemahaman konsep. Kata kunci: analisis, buku ajar, TPACK Abstract. The research has been conducted on analysis of thermodynamics textbook content in order to determine the needs of the use of the modules base on Technological Pedagogical And
