Sundial Developments in Surrounding Communities: Study at Qowiyuddin Jagir Mosque and Peneleh Mosque, Surabaya

Abstract

: The use of traditional tools at the present time is considered less attractive and has resulted in gradually being abandoned. Especially in the field of Astronomy, there are technological developments that have supported the use of more practical tools or instruments. One of them is a sundial, which is a simple instrument that can tell time using the concept of the sun's shadow. The use of this tool is very rare. Researchers conducted a search and managed to find related to this traditional tool, namely at some of the oldest mosques in Surabaya, namely the Qowiyuddin Jagir Mosque and the Jami' Peneleh Mosque in Surabaya. The two mosques still use the classical device to determine the start of their prayer times, namely by using the Sundial. Both the Qowiyuddin Jagir Mosque and the Jami' Peneleh Mosque in Surabaya have their own mention of the Sundial they use. For example, the Qowiyuddin Mosque calls it Pandem, while the Jami Peneneleh Mosque calls it Bencet. Based on that, the researcher wants to dig deeper into the development of the use of Sundial or Pandem or Bencet in the surrounding community, especially at the Qowiyuddin Jagir Mosque and the Jami' Peneleh Mosque in Surabaya. With this research, it is hoped that it can become a source of knowledge related to the development of the use of Sundial itself.
