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%.

Informasi artikel ABSTRAKSejarah artikel: Dikirim Revisi Diterima Karakteristik CO2 saat gerhana matahari 83,16% di Yogyakarta telah dilakukan. Penelitian ini bertujuan untuk mengetahui proses perubahan kadar CO2 pada saat gerhana matahari. Penelitian ini menggunakan metode eksperimen. Pengumpulan data dilakukan dengan bantuan sensor CO2 Logger Pro. Metode analisis penelitian ini menggunakan analisis grafik. Dari hasil eksperimen diperoleh bahwa rata-rata kadar CO2 meningkat dari 659,0932 ppm menjadi 662,632 ppm, dan setelah terjadi gerhana matahari rata-rata kadar CO2 kembali turun menjadi 654,702 ppm.This is an open access article under the CC-BY-SA license
Perilaku Reptilia di Pasar Aneka Satwa & Tanaman Hias Yogyakarta diamati ketika peristiwa gerhana matahari parsial pada 9 Maret 2016. Faktor lingkungan seperti intensitas cahaya, suhu, dan kelembaban udara diamati dan dicatat. Perilaku Kura-Kura, Biawak, dan Ular diamati dengan metode focal point sampling. Ular cenderung memiliki pergerakan yang terbatas, sedangkan biawak dan kura-kura diam sejenak. Perbedaan perilaku reptilia ketika gerhana matahari sebagian ditentukan oleh jenisnya dan faktor lain yang berbeda-beda.
