Abstract

Physical practicum-based learning on collision was been carried out with the aim of knowing the magnitude of the coefficient of restitution of collision of 2 toy balls that are hung on station with a rope by analyzing the conversion of angle of the deviation before and after collision to the magnitutde of  velocity. The instruments used in the practicum were“ tek-tek” balls, “ping-pong” balls, clear rubber ball, bow, stationary. Data collection was taken from the 8 practicum groups each of which  consists of 4 students in class X IPA 1 of Senior High School 2 Kebumen in the 2nd semester of the school year 2017/2018. Conclusions obtained from data analysis are the conversion of angle of deviation before and after collision to the magnitude of velocity, average collision coefficient; between “tek-ball” was  0.18, “tek-tek” ball with clear rubber ball was 0.26, “tek-tek” ball with “pingpong” ball was 0.64. So that the three collisions include a partially resilient collision which has a range of restitution coefficients 0 ˂ e ˂ 1.Students did the practicum carefully, students had fun learning while playing and collision. This practicum can be done as an alternative to teach the competency on KI-4

Abstract

Learning Physics on the diffraction of light through a practical on diffraction learning material using a toy laser beam as the source of monochromatic light has the obyectives to know the wavelength of a toy laser beam  and to improve  students’ learning activities. The practical was conducted in groups consisting of 10 groups each of which consists of 3 students of Senior High School 2 Kebumen in class XII ScienceA, 2014/2015 school year. The conclusions from the data analyses and observations during the learning process are; the wavelength range of the toy laser beam is on average 649 nm - 662 nm, and the laser beam as the source of monochromatic light on the diffraction learning material shoured the same monochromatic light on the screen. The student’s learning activity showed an increasing tendency indicated their active involvement in the learning process when stringing tools, observing, recording, data process, concluding and reporting their practicals. Based on the illustration mentioned above, it can be concluded that the toy laser beam can be used as an alternative source of monochromatic light which is afordable and obtainable for the teaching of  light diffraction throngh practical

Abstract

Telah dilakukan penelitian rangkaian jembatan wheatstone berbasis simulasi PhET. Tujuan penelitian adalah menganalisis besar hambatan R1, R2, R3, dan R4 yang menyebabkan besar arus listrik yang melewati hambatan R5 nol dan tidak nol, Pengambilan data menggunakan aplikasi simulasi PhET circuit-construction-kit-ac-virtual-lab_en, oleh 11 kelompok praktikum: 32 peserta didik kelas XII IPA1 SMA Negeri 2 Kebumen semester ganjil tahun pelajaran 2019/2020, diperoleh simpulan; besar arus listrik yang melalui hambatan R5 menghasilkan nol, diperoleh dari analisis hasil perkalian silang antara R1 dengan R3 sama dengan hasil perkalian silang antara R2 dengan R4, rangkaian  tersebut dalam keadaan seimbang dan besar arus listrik yang melalui R5 menghasilkan tidak nol, diperoleh dari hasil analisis perkalian silang hambatan R1 dengan R3 tidak sama dengan hasil perkalian silang antara R2 dengan R4, rangkaian tersebut dalam keadaan tidak seimbang. .Kata kunci: jembatan wheatstone, simulasi PhET
