Siswa sekolah dasar dituntut memiliki keterampilan membaca yang baik, namun kemampuan membaca permulaan siswa Sekolah Dasar masih tergolong rendah. Pengembangan media game edukasi berbasis kearifan lokal dilakukan dengan tujuan meningkatkan kemampuan membaca permulaan siswa Sekolah Dasar kelas I. Media game edukasi berbasis kearifan lokal dikembangkan dengan metode ADDIE yang terdiri dari analyze, design, development, implementation dan evaluation. Hasilnya, media game edukasi berbasis kearifan lokal dapat dilihat dari hasil validitas yang diperoleh dari dua pakar dan hasil keefektifan dari aktivitas dan respon siswa yang menyatakan media game edukasi sangat valid untuk bisa digunakan oleh siswa di sekolah dasar dengan dibuktikan dengan uji coba tebatas dan uji coba lapangan, yang dilakukan untuk mengukur respon siswa terhadap penggunaan media game edukasi berbasis kearifan lokal dengan hasil yang sangat baik serta dapat digunakan oleh guru untuk meningkatkan kemampuan membaca permulaan yang dibuktikan melalui hasil uji-t uji-t 0,034 < 0,05. Hasil uji N-Gain menyatakan adanya peningkatan membaca permulaan siswa kelas I di sekolah dasar dengan persentase 75,10% dengan kategori efektif. Secara keseluruhan disimpulkan bahwa media game edukasi berbasis kearifan lokal dinyatakan layak digunakan dalam meningkatkan kemampuan membaca permulaan siswa.
An antenna radiation pattern experiment has been carried out with the aim of determining the patch antenna radiation pattern on a logarithmic and linear scale, understanding the properties and principles of the antenna, and understanding the types of antenna radiation patterns. In the experiment, the angle, frequency, and radian intensity data were obtained, and the value of the linear intensity was calculated. With the principle of converting electrical signals into electromagnetic signals. a graph between angle and intensity is obtained. the graph between radian intensity and angle forms a circular pattern, in which the value of intensity and frequency at each point with a difference of 5 degrees has almost the same value. In conclusion, the antenna is a structure that can receive and release electromagnetic waves in the air. The patch antenna used has a unidirectional radiation pattern. Converts electromagnetic signals into electrical signals and vice versa, has a certain radiation pattern, and is easily disturbed by metallic materials.
The learning model used so far is still less effective, which is one of the reasons for the low learning outcomes of mathematics in students. This study aims to analyze the needs of the learning model on students' mathematics learning outcomes. This research is a qualitative research with qualitative description research type. The research subjects were students of class VIII Junior High School. The research data were collected by means of interviews and observations. The results of this study indicate that: (1) the teacher has not been precise in choosing the learning model (2) students have not been actively involved in learning in class (3) students still do not dare to ask if they have difficulties so that the learning process is not effective (4) students in the teaching and learning process only listen, take notes, do what the teacher tells them to do and do not dare to ask for difficulties in understanding the material. Therefore, it is necessary to decide the right learning model in the teaching and learning process of mathematics in order to make it easier for students to accept the material presented.
This study aims to improve students' ability to understand fraction comparisons of sixth graders at SD Muhammadiyah 1 Babat by using the CALILANG strategy. This type of research is classroom action research. The subjects in this study were students of class VI SD Muhammadiyah 1 Babat, totaling 10 students. Data collection techniques were carried out by observation, test, and documentary techniques. The research instrument used an observation sheet and a written test. The data analysis technique uses the mean formula whose results are presented in a qualitative descriptive form.
Superposition of waves experiment in physics subject need more innovation to dig up student knowledge about the essential of waves in physics. Such innovation is using Audacity software for analyze it. The purpose of this study is to analyze the superposition of sound waves using Audacity software in the wave superposition experiment. The method used is to prepare tools and materials, namely PC/laptop, 250 Hz, 1 kHz audio files and Audacity Software. Then, 250 Hz and 1 kHz audio is sampled in one wave using Audacity after which each audio sample is imported twice and then combined with Audacity software and saved. This is done for different audio frequencies as well. Then, the results of the merger are opened with Audacity and then analyzed and compared with the initial wave. And the resulting superposition of two 250 Hz waves produces an amplitude of twice and 250 Hz and 1 KHz is produced over a 4 ms wave period and the constructive and destructive wave amplitudes depend on the phase of the two waves. Thus, wave superposition experiments using Audacity software facilitate the analysis of superposition results and characterize the period and amplitude properties of waves.
