Physic Education and Technology (PhET) adalah salah satu media pembelajaran yang diciptakan untuk memberikan pengalaman interaktif bagi peserta didik. Penelitian ini bertujuan untuk meningkatkan pemahaman konsep fisika peserta didik dengan menggunakan PhET Simulation. Penelitian ini dilakukan di MTs AT-Taqwa Maumere, dengan sampel 58 peserta didik. Teknik pengambilan sampel pada penelitian ini adalah dengan cara purposive sampling.Jenis penelitian ini merupakan penelitian kuantitatif. Penelitian ini dilakukan dengan metode Quasi Experimen, dengan bentuk Nonequivalent Control Group Design yang melibatkan dua kelompok belajar yaitu kelas eksperimen dan kelas kontrol dimana sampel kedua kelas ini dipilih tidak secara random. Pengumpulan data dilakukan dengan pemberian soal test kemampuan pemahaman konsep. Teknik analisis data menggunakan uji N-gain. Hasil penelitian dengan mengacu pada perhitungan N-gain menunjukan bahwa kelas eksperimen lebih tinggi dari pada kelas kontrol. Peningkatan pemahaman konsep fisika pada kelas eksperimen sebesar 0,62 sedangkan untuk kelas kontrol sebesar 0,13. Berdasarkan hasil perhitungan n-gain dapat dikatakan bahwa pembelajaran dengan menggunakan PhET Simulation dapat meningkatkan pemahaman konsep fisika peserta didik.

This study aims to determine the effect of flight activity noise intensity on student learning concentration. This study involved 48 students (male = 24 and female = 24) who were randomly selected in the Islamic elementary school Waioti, Maumere. The intensity of flight activity noise during classroom learning activities is measured using a Sound Level Meter (SLM), and students' concentration levels were measured using a 5-level Likert scale learning concentration questionnaire. The effect of flight noise intensity on student learning concentration was determined using linear regression analysis. The results showed that the noise level due to flight activities in the Waioti Islamic Elementary School was 58.92 dB, exceeding the set threshold value. The intensity level of students' learning concentration disorders reached 71.43%, including frequent disturbance. The level of flight activity noise significantly affects student learning concentration with the regression model: Y = 49.972 + 0.834X with R2 of 0.635.

Solid-state is a compulsory subject in the Physics Education study program. Therefore, the level of complexity—depth—of the material taught is moderate. However, students are facing some obstacles in understanding crystal structure material that is related to microscopic structures. This research aims to apply diamond software media to crystal structure material, from which students' scientific attitudes can be discovered. The method used in this study is the qualitative description. The research subjects totaled 23 students. The data collection technique was carried out by measuring students' scientific attitudes after using the Diamond software. The results showed that the Diamond software could be used in Solid State Physics course. In contrast, the scientific perspective showed good results, which is indicated by the scientific attitude questionnaire score reaching more than 80% within the high category. Meanwhile, student responses indicate that the acceptance rate of Diamond software as a learning medium in Solid State Physics course is 86.25%, or falls into the high category.

Tapes, radio, laudspeakers, TV, and VCDs are all sources of organized and controlled sound. However, if this regular and controlled sound emits a sound that exceeds the desired sound level threshold and declared as noise that causes disturbances to human health, especially the sense of hearing. Hearing apparatus, namely the ear functions as a phonoreceptor capable of responding to sounds in the range 0 - 75 dB without causing pain. The frequency to which the human ear can respond is between 20 - 20,000 Hz and is very sensitive to frequencies between 1000 Hz - 4000 Hz. This study aims to determine how much the measured sound intensity level of the music sound at the Sinta Pub Maumere Bar and determine the degree of music sound intensity level at the Sinta Pub Maumere Bar at the measuring point of the sound source. This research was conducted at the Sinta Pub Maumere Bar using observation and experimental methods. The results showed the measured level of music sound intensity ranged from 103.12 dB. The highest level of sound produced is 110.6 dB and the lowest music sound intensity level produced is 92.4 dB. Based on the measurement results, the music sound intensity level at the Sinta Pub Maumere Bar has a different value. This shows that there is a difference measuring levelat the position of the distance from the sound source to the intensity level of the resulting music sound.
