Abstract

The aimed of this sudy are: (1) investigate the effectiveness of E-Lab to improve generic science skills and understanding the concepts oh physics; and (2) investigate the effect of generic science skills towards understanding the concept of students after learning by using the E-Lab. The method used in this study is a pre-experimental design with one group pretest-posttest. Subjects were students of Physics Education in University PGRI Semarang with methode random sampling. The results showed that: (1) learning to use E-Lab effective to increase generic science skills of students; and (2) Generic science skills give positive effect on student conceptual understanding on the material of the photoelectric effect, compton effect, and electron diffraction. Tujuan penelitian ini yaitu: (1) menyelidiki efektifitas E-Lab untuk meningkatkan keterampilan generik sains dan pemahaman konsep mahasiswa; dan (2)  menyelidiki pengaruh keterampilan generik sains terhadap pemahaman konsep mahasiswa setelah dilakukan pembelajaran dengan menggunakan E-Lab. Metode penelitian yang digunakan dalam penelitian ini adalah pre-experimental dengan desain one group pretest-posttest. Subjek penelitian adalah mahasiswa Program Studi Pendidikan  Fisika  Universitas PGRI Semarang, dengan metode pengambilan sampel penelitian secara random. Hasil penelitian menunjukkan bahwa bahwa: (1) pembelajaran menggunakan E-Lab efektif untuk meningkatkan keterampilan generik sains mahasiswa; dan  (2) Keterampilan generik sains berpengaruh positif terhadap pemahaman konsep mahasiswa pada materi efek fotolistrik, efek compton, dan difraksi elektron.

Abstract

Numerical methods are used to solve the differential equations in the case of a damped pendulum system. In this paper, we aim to solve the equation of dumped pendulum motion using some numerical. Four numerical methods are decomposed, each the Euler method, fourth-order Runge-Kutte, Odeint provided in Python, and Neural Network scheme. All answers obtained are approximations or predictions that include errors. The error of those methods will be compared with the analytical solution of the case, known as the global error. The Odeint and fourth-order Runge-Kutta methods are more accurate than the other methods. The Odeint is built from the Runge-Kutta fourth-order method.The Neural Network method has less accuracy than Runge-Kutta, but the error obtained is still within acceptable tolerance limits.
