Abstract

One of the interesting physical phenomenon to be studied is about eccentricity of the Moon's orbit on the movement of the Earth and the Moon as explained in Kepler's Law. In order to explain the phenomenon,several research has been done to determine the measurement accuracy of Moon disk diameter using Trackers and to know the result of the eccentricity value in the application of Kepler's Law. This research can produce eccentricity values accordance with the application of Kepler’sLaw. The research method used is Image Analysis Techniqueassisted with Tracker. The result of this research shows that the eccentricity value obtained is 0.07 ± 0.01. This is in accordance with Kepler's first Law which stated that orbits of each planet and satellite is an ellipse and has an eccentricity value of 0 <e <1. The value of eccentricity obtained has accuracy of 22%,if it compared with the actual value.Whereas, if it compared with the value of ephemeris then the value of accuracy is 8%.

Abstract

Resitasi method is a method of teaching that enable learners to perform the tasks assigned by the teacher after explaining the topic. The tasks referred to here is solving problems that prepared by the teacher and will be distributed to each learner. This research is experimental research design used randomized posttest-only control group design, in order to compare the results of experimental physics learning between classes taught using the control class resitasi method taught using conventional methods. Number of students in the experimental class and control class that equal numbers of each class consists of 28 people. Through testing shows that the normality of the population come from a normally distributed population and the variance is homogeneous. In the descriptive analysis of learning outcomes visible difference in scores between grade physics experiment and control class that is 18.82 with a standard deviation of 5.02 in the experimental class while the control class of 16.14 with a standard deviation of 5.03. From the results of hypothesis testing shows that there are differences in learning outcomes among learners experimental class and control class using sigifikansi level α = 0.05. It can be concluded that learning by using the method of recitation is more influential than the learning using conventional methods in achieving the goals of learning physics.Keywords: Resitasi, Learning Outcomes, Experimental Class, Control Class, Learning PhysicsMetode resitasi merupakan metode pengajaran yang mengaktifkan peserta didik untuk mengerjakan tugas-tugas yang diberikan oleh guru setelah menjelaskan suatu materi. Tugas-tugas yang dimaksud disini adalah menyelesaikan soal-soal yang telah disusun oleh guru dan akan dibagikan kepada setiap peserta didik. Penelitian ini merupakan penelitian eksperimen dengan desain penelitian yang digunakan adalah Randomized posttest-only control group design, yang bertujuan untuk membandingkan hasil belajar fisika antara kelas eksperimen yang diajar dengan menggunakan metode resitasi dengan kelas kontrol yang diajar dengan menggunakan metode konvensional. Jumlah peserta didik pada kelas eksperimen maupun kelas kontrol sama jumlahnya yaitu masing-masing kelas terdiri dari 28 orang. Melalui pengujian normalitas terlihat bahwa populasi berasal dari populasi  yang terdistribusi normal dan varians yang homogen. Pada analisis deksriptif terlihat perbedaan skor hasil belajar fisika antara kelas eksperimen dan kelas kontrol yaitu 18,82 dengan standar deviasi 5,02 pada kelas eksperimen sedangkan pada kelas kontrol 16,14 dengan standar deviasi 5,03. Dari hasil uji hipotesis terlihat bahwa terdapat perbedaan hasil belajar antara peserta didik kelas eksperimen dan kelas kontrol dengan menggunakan taraf sigifikansi α = 0,05. Sehingga dapat disimpulkan bahwa pembelajaran dengan menggunakan metode resitasi lebih berpengaruh jika dibandingkan dengan pembelajaran yang menggunakan metode konvensional dalam mencapai tujuan pembelajaran fisika.Kata kunci: Resitasi, Hasil Belajar Fisika, Kelas Eksperimen, Kelas Kontrol
