The coastal environment is a very dynamic environment and is prone to the dangers of erosion, abrasion, landslides, land subsidence, tidal flooding, and others. Krapyak lor village, North Pekalongan District, Pekalongan City is located on the north coast of Java, which is an area prone to tidal flooding. This area is located in the lowlands (<2 meters above sea level) and has a relatively flat land surface (slope slope <8%), making it vulnerable to inundation. This tidal flood has disrupted community activities. Recent research states that tidal flooding can be predicted when and how big it will be. The purpose of this service is to create and introduce a smartphone-based rob calendar application. The use of this application certainly adapts to current technological developments, where smartphones have become a basic need of society. This smartphone can also always be carried as long as they are active as a means of communication and of course easy to operate. This rob calendar smartphone application can provide data and information related to when the rob date and time will occur. The date informed is adjusted to the calculation of the Gregorian calendar and the calculation of the Javanese calendar. Additional data in the application, in addition to the date and time, is also information about the predicted water level and the duration of tidal events in the area.
