Pengukuran periode revolusi planet venus di lingkungan forum komunikasi astronom amatir lintas Jawa Timur (FOKALIS JATIM)

Abstract

The development of astronomy in Indonesia could not have been disconnected from the  activities of amateur astronomy communities. These communities served as platforms for the  exchange of knowledge and information among individuals who shared a passion for  astronomy. In East Java, there were more than 29 astronomy communities distributed across  various geographical areas, including universities and schools, complemented by the presence  of overarching organizations that served as communication forums for each community. The  Forum Komunikasi Astronom Amatir Lintas Jawa Timur (FOKALIS JATIM) was an  organization that facilitated the active involvement of amateur astronomy communities and  practitioners. The method employed for measuring the period of revolution of the planet Venus  served as an example of research activities undertaken by one of the members of FOKALIS  JATIM. Data acquisition involving the imaging of Venus's phases over a two-month interval  was used as a means to measure the period of Venus's revolution. The findings underscored the  significance of the active engagement of amateur astronomy communities and practitioners as  a means to enhance public understanding of astronomy.
