Abstract

This study was conducted to determine the gravitational field of the Earth's surface anomaly (g) due to the partial solar eclipse. Large gravity field of Earth's surface can be obtained using a pendulum swing period. Data were collected for three days on 8, 9, and 10 March, 2016 from at 6:00 to 9:00 pm in Bandung with coordinates 6°51'48 " LS, 107°35'40" BT. The tools used in this research was Kater's reversible pendulum with a deviation of less than 3° so that the motion can be regarded swing harmonics. Pendulum swinging motion is recorded using high resolution cameras (High definition) with a shooting speed 24 of frames per second (fps), the video is analyzed using the tracker in order to obtain the period of a pendulum swing. The results show the value of the gravitational field of the Earth's surface on a three-day consecutive sampling of 10,33153834, 10,18560435, and 10,32046468. According to the research there are anomalies in the gravitational field of the Earth's surface (g) due to the partial solar eclipse with the value of the gravitational field which decreases the time of the eclipse. Keywords: Eclipse, Tracker, Kater’s Reversible Pendulum.

Abstract

This study was conducted to determine the effect of partial solar eclipse (GMS) to the acceleration due to gravity (g) the perceived objects on the Earth's surface. Data is collected in Bandung with the coordinates of 6°51'48 "S, 107°35'40" E for three days on 8, 9 and March 10 2016 with a span of 07.00 to 08.00 am. Earth's surface gravitational acceleration (g) is determined from the period of a pendulum swing that moves harmonics. The instrument used is the mathematical pendulum are optimized by material type nylon rope to prevent the rotational motion of the pendulum, the use of mirrors board to identify and eliminate Conic motion of pendulum and analysis tracker for the determination of the period of a pendulum precisely. Data were collected by recording the pendulum swing using high-resolution cameras with a shooting speed of 24 frames per second (fps), the video is analyzed using application tracker in order to obtain the period of a pendulum swing. The results showed a mean value of the Earth's surface gravitational acceleration (g) of the third day in a row is 9.81524 m s2, 9.808285 m/s2 ,and 9.813122 m/s2. Based on the results of this study concluded that the Earth's surface gravitational acceleration (g) is influenced by partial solar eclipse. Keywords: Eclipse, Tracker, Mathematical Pendulum.
