Semarang City is one of the big cities in the northern region of Java Island. The city of Semarang has a beach length of ± 13.6 KM and most of the beaches have a sloping topography. The topography which is almost as high as sea level makes the danger of tidal flooding a threat. Rob is a flood that occurs due to tides that inundate areas that have an altitude lower than sea level at the highest tide. The duration of inundation can last for days or even throughout the year. Many studies say that tidal flooding enters through 3 major rivers in Semarang, namely Kali Semarang, Kali Baru and Kali Banger. Tambakrejo, Tanjungmas, North Semarang is an area that is often affected by tidal inundation. Previous services have been given a tidal calendar to find out when and the magnitude of the tidal flood will occur. The purpose of this community service is to update the rob 2021 calendar data based on a smartphone. Tambakrejo village is close to industrial areas, making rob prevention an important aspect. People who have high mobility can easily take advantage of this rob calendar application. The appearance of this application is simplified so that people can easily read the information provided and immediately notify other people. The community is enthusiastic in participating in this service activity but continues to implement health protocols so that the health of the participants is maintained. The rob calendar is expected to increase residents’ knowledge and increase mitigation efforts and awareness for the related community long before the tidal flood inundates the area.
