Abstract

Peer teaching adalah model pembelajaran yang memungkinkan siswa saling memberi pengetahuannya kepada sesama rekannya atau mengajar teman sejawatnya. Peer teaching merupakan salah satu metode pembelajaran yang berpusat pada peserta didik. Tujuan dari penelitian ini adalah (1) mengetahui hasil belajar mahasiswa setelah menerapkan model pembelajaran peer teaching (2) mengetahui peningkatan hasil belajar mahasiswa setelah menerapkan pembelajaran peer teaching. Metode yang digunakan dalam penelitian ini adalah Quasi Experimental (ekperimen semu). Teknik pengumpulan data dalam penelitian ini adalah menggunakan teknik tes yang terdiri dari pre test dan post test. Analisis data dalam penelitian ini Uji N-Gain, Uji Normalitas, Uji Homogenitas dan Uji-t. Hasil penelitian dapat disimpulkan (1) nilai rata-rata mahasiswa pada kelas yang menerapkan model pembelajaran peer teaching berkategori sedang. (2) model pembelajaran peer learning dapat digunakan sebagai upaya untuk meningkatkan hasil belajar mahasiswa.

Abstract

This study aims to determine students' analytical skills in solving physics problems using the Contextual Teaching and Learning (CTL) learning model. The type of research is descriptive research. The research data shows that in the initial test the average value of the in itial ability of students is 15,84 seen from the analytical ability of C2 of 38,88%, C3 of 18,75%, C4 of 21,52%, thus the average initial ability of students is classified as a failed qualification. The average value of students' analytical skills during the learning process is 81,01% with the complete category. The final a bility data average value is 81,14, seen from the analytical ability of C2 of 83,33%, C3 of 75%, C4 of 72,54%. Thus, it can be concluded that the CTL learning model can be used to analyze the ability of students to solve problems.

Abstract

An Arduino Uno-based static friction coefficient (µs) determination tool equipped with an IR sensor module FC-51 has been created. This µs determination tool is made to reduce the possibility of observation errors when doing physics labs. The µs determination tool consists of an FC-51 IR sensor component to detect precisely when an object is moving. The potentiometer measures the angle of the base surface, and an Arduino Uno device transmits data from the hardware to the computer in real time. The work test of the µs determination tool starts with the base surface with a slope of 0o, and then the object is placed on the base surface and precisely above the surface of the FC-51 IR sensor. When the base surface is tilted slowly, the potentiometer also rotates, showing the plane angle's size. As long as the object is not moving, the IR FC-51 sensor is in low condition. When the object moves, the IR FC-51 sensor is in high condition. The change in signal from low to high indicates that the object is moving when the plane reaches the slope angle, and the slope angle shows the value of µs. The µs are measured on a wooden base with wooden blocks and a glass base with glass blocks. The results obtained for a wooden base with wooden blocks µs = 0.73 with an average slope angle = 36.16o and a glass base with glass blocks µs = 0.4 with an average slope angle = 22.1o. The results show that the µs level of the wood surface with wood is greater than the µs level of the glass surface with glass.

Abstract

An instrument for measuring I-V characteristics and determination of the dynamic resistance of a Silicon 1n4002 diode based on Arduino Mega 2560 has been successfully developed. This measurement was carried out by increasing the bias voltage periodically from 0 V to 5 V and observing the resulting forward voltage and forward current for each increase in the bias voltage. There is an increase in current when the diode voltage reaches 0.7 V, which is the diode barrier voltage. This happens if the limit resistor installed in the circuit is 100 Ω. The largest dynamic resistance value is 593.069 Ω, which is below the forward voltage of 0.6 V. Furthermore, the smallest dynamic resistance value is 2.293 Ω which is above the forward voltage of 0.7 V. The greater the value of the current flowing in the diode circuit, the smaller the dynamic resistance value of the diode and the smaller the value of the current flowing, the greater the dynamic resistance of the diode.

Abstract

This research aims to analyze the effect of load mass on the damping coefficient of liquid substances such as water, cooking oil, and oil. The load masses used are 71 grams, 81 grams, 91 grams, and 101 grams. This study employs an experimental method with a damped oscillation analysis approach aided by Origin software. The research results indicate a significant influence of load mass on the frequency (Hz) and damping coefficient (γ) values of the liquid substance, where the larger the load mass, the higher the frequency (Hz) and damping coefficient (γ) values of the liquid substance. The study also examines the damping constants of each liquid substance. The results show that the damping constants of each liquid substance, namely water, cooking oil, and oil, are respectively 0.049 kg/s, 0.107 kg/s, and 0.201 kg/s.
