More than twenty years after the first exoplanet, 51 Pegasi b, detected in 1995, the presence of more than three thousand exoplanets have been confirmed. From 3525 exoplanets discovered as of September 11th 2016 (http://exoplanet.eu/catalog/), about 17% are the multiplanetary systems and more than 75% of them were detected using the transit photometry method. Therefore, <br /> <br /> this detection method has proven to be very productive. Moreover, from the theoretical point of view, the formation of planetary system in solar-like as well as <br /> <br /> low mass stars should be very common. The numerous recent discovery of exoplanets seems to confirm this hypothesis. <br /> <br /> We report our observational programs undertaken at Bosscha Observatory, Lembang (West Java), and Kupang (East Nusa Tenggara), from March to July 2016, aiming mainly at multiplanetary systems. The selection of instrument and <br /> <br /> object as well as observational methods are described. Object selection takes into account the visual magnitude, relative flux, declination of observation, orbital periods, and represents known multiplanetary systems. There are six observational nights with the clear sky condition that produce nine data packages. Data analysis <br /> <br /> were made by using PyTransit (Parviainen, 2015).
