Abstract
This study using data of hilaal observation compiled by the Ministry of Religious Affairs (MORA) Republic of Indonesia during 1962-2011 period, the observational data of Rukyatul Hilal Indonesia (RHI) during 2007-2009 period and Odeh’s international observational data during 1859-2005 period. Those data were selected by applying selection procedure of Djamaluddin (2001) and by eliminating hilal data whose angular distance < 3° between hilaal and particular planet. Next, selected data were plotted to graphic of Sun-Moon altitude difference (ARCV - Arc of Vision) and Sun-Moon angular distance (ARCL - Arc of Light), moon age and Sun-Moon angular distance (ARCL - Arc of Light) and Sun-Moon altitude difference (ARCV - Arc of Vision) and Sun-Moon angular distance (DAz - Delta Azimuth) to propose the new hilaal visibility criteria in Indonesia. The new criteria proposed are ARCL greater than 5.4°, Moon is as old as 9.4 hours after conjuction and = 3° if DAz 5° ARCV -0.719(DAz)+6.795 if DAz < 5° .
