Abstract

Poso Regency has great potential to be developed into a marine tourism and fisheries city due to its 64.6 km coastline, extending from Tumora in North Poso Pesisir District to Malei in Lage District. For the development of a marine tourism and fisheries city in Poso Regency, data related to wave height and period are required. One method for measuring wave height and period in a body of water is the JONSWAP (Joint North Sea Wave Project) method, an advancement of the Pierson-Moskowitz (1964) method. The JONSWAP method incorporates fetch length and wind speed parameters for calculating wave height and period, whereas other methods only use fetch length. This study aims to analyze wave height and period in Tomini Bay, using the JONSWAP method. The results show that the wind direction dominantly from the north, with most wind speeds (67.71%) being below 0.5 m/s. Wind gusts from the southeast were not detected on the wind rose because the area is located in the Verbeek Mountains; thus, southeast winds can be deflected. The average wind speed is 1.533 m/s, the significant wave height is 0.09 m, the peak wave period is 3.603 seconds, and the wave type is non-fully developed sea.

Meanwhile, landslides hit Paal Dua District, Tikala District, Singkil District, Wanea District, Bunaken District, Mapanget District and Wenang District. The flood and landslide disaster claimed 6 lives, resulted in 219 houses being heavily damaged, 166 moderately damaged, 761 lightly damaged, several public facilities such as schools, churches, mosques and sub-district offices being flooded and causing ± 279 families/1,925 people to flee to the nearest village. Based on the flood conditions in the city of Manado, the PKM Team from the Faculty of Engineering, Sintuwu Maroso University carried out community service activities after the flash flood and landslide disaster in Manado. From the results of the PKM Team's activities after the flood and landslide in Manado, it can be concluded that the people in the 3 sub-districts visited for the PKM activities were very enthusiastic and grateful, especially for the trauma healing activities, because these activities were very helpful and motivating for the children at the location. Refugees are entertained and do not get lost in post-disaster sadness. Apart from that, the Manado City government hopes that similar activities will be carried out in other refugee camps to alleviate trauma in children.
