Semarang – Science and Technology Community Service Team for Undip Assisted Villages (IDBU) Department of Oceanography FPIK Diponegoro University provided updating data on Coastal flooding Calendar 2020 in the coastal area of ​​Tambakrejo, Tanjung Mas Village Semarang on Saturday, September 19 2020 to the residents and community as well as their leaders.

The socialization of the use and updates of the 2020 Coastal flooding Calendar data is a continuation of the collaboration between Pokmaswas and the Community Service Team of the Oceanography Department of Diponegoro University which was carried out through the Science and Technology Program for Undip Assisted Villages (IDBU) during 2018-2020.

According to the head of the IDBU Undip Team, Prof. Dr. Denny Nugroho Sugianto, ST., MSi., this event aims to create a community that is resilient to coastal disasters in Tanjungmas Village, Semarang – Central Java, due to coastal flooding which is a part of the life of the local community at any time. Coastal flooding’s calendar is very beneficial for today’s society. The community can easily predict when the coastal flooding occurs, how high it will be, how long it will last, and how the water level is in the coastal flooding, so that people can anticipate efforts by preparing to move things or save some furniture in order not to be flooded by the sudden coastal flooding water. Another benefit felt by residents is when they will have social events, religious events, and even wedding receptions. Residents can see the coastal flooding calendar to determine the right time so it doesn’t coincide with coastal flooding’s occurrence. In addition, it is also useful as information for short, medium, and long- term mitigation for the government, stakeholders, and the community related to coastal flooding that occurs in coastal areas. This is also one of Diponegoro University attempts of implementing the government’s agenda, namely the Sustainable Development Goals (SDGs) with the goals of SDGs 13 (climate action) and 17 (partnerships for the goals), namely strengthening implementation measures and revitalizing global partnerships for sustainable development. sustainable. Sustainable Development Goals (SDGs) are global action plans agreed upon by world leaders, including Indonesia, to end poverty, reduce inequality and protect the environment. The SDGs contain 17 Goals and 169 Targets that are expected to be achieved by 2030.

As we know, the tidal flooding, known as coastal flooding, is an event in nature caused by sea level dynamics that are detrimental and disrupting normal life. Tidal disasters are a thing. These types of disasters are generally caused by excessive sea level rise to reminisce on land surface, to which one of the causes is due to global climate change.

The Development of Digital Flood Technology Install

The same thing is felt by some local residents, for example the Head of RT 04 RW 16, Mr. Suratno who is assigned as the Head of the Manunggal Bahari Community Supervisory Group (Pokmaswas) spoke in behalf of the residents. He conveyed that the existence of the coastal flooding calendar is very useful as it helps residents to determine the upcoming events held in the village. According to the chairman of RW 16 Tambakrejo Tanjungmas, Mr. Slamet Riyadi, the coastal flooding calendar, which has been made for several years by the Undip IDBU Team from 2018-2020, and given to the residents is so beneficial and it helps residents in their daily life which cannot be separated from coastal flooding that can occur any time. With this calendar, current residents can anticipate and be able to save their belongings before the flood comes.

Furthermore, one of the team members, Dr. Muhammad Helmi, said that this coastal flooding calendar has 2 versions, namely digital and manual (regular calendar form). For the digital form, the Android-based coastal flooding calendar application can be downloaded via the Play Store. It displays water level conditions of each day that shows information regarding the highest water level and the lowest water level in meters. Data is displayed live hourly and daily, as well as the information on the water level whether it is still in a safe level, alert 1, alert 2, and standby. There is also information about the Gregorian and Javanese calendars as well as information on the position of the moon. Currently the coastal flooding calendar application only provides data in Semarang City and its surroundings, and is in the development stage for the entire north coast of Central Java, and will continue to be developed to the areas prone to coastal flooding.

The development of digital flood tide technology in the form of an android-based coastal flooding calendar can be an effective alternative solution for people in exposed areas, industrial and service trade activities, and local governments to do mitigation. The digital coastal flooding calendar can provide data and information about the date and time when the coastal flooding occurs according to the Gregorian Calendar calculations and the Javanese calendar calculations. The coastal flooding calendar also provides quantitative data and information on the water level and duration of coastal flooding in the area.
