Parking is a phenomenon that affects the movement of vehicles when vehicles that have such a high intensity will be hampered by vehicles parked on the road, causing congestion. Vehicles parked on the roadside are generally around places or activity centres such as offices, markets, schools, and restaurants. Maximum vehicle volume without on-street parking occurs in segment 1 on Monday at 16:30, with the number of vehicles amounting to 2154.3 SMP/hour with a capacity value (C) = 2375 SMP/hour; the degree of saturation value (DS) is obtained. =0.91. This shows that the level of service is included in category E, which means that segment 1 has unstable flow, decreased speed, and vehicle motion is approaching capacity. When parking occurs on the road, the capacity value decreases to (C) = 1243.01 SMP/hour s...

Thus, the more rain stations there are, the more detailed the rainfall data will be. The rain station network density is expressed as the area of the watershed represented by one rain station. Meanwhile, the pattern of distribution of rain stations states the location of the placement of rain stations in the watershed. Ternate Island with an area of 76 km2 and has stations located in Akehuda Village, Gamayou Village, Tabona Village, Sasa Village, Kastela Village, and Sulamadaha Village. This study aims to rationalize the density of rainfall stations in Ternate Island. Rationalization of rainfall stations using the Kagan-Rodda method. The results obtained for the rationalization of rainfall stations with a total of 5 rain gauge stations spread across the city of Ternate, which are located in the Tabam, Gamayou, Sasa, Dorpedu, and Togafo areas with a grading error of 19.27% with a network density of 4.17 Km²/station.

In order to determine the optimal selection of weights for the factors that contribute to flood risk, GIS and multi-criteria decision analysis (MCDA) were used in conjunction with the application of the analytical hierarchy process (AHP) method to create the flood hazard map. The flood hazard map was generated by using selected hazard factors including land use, topography, slope, and rainfall pattern. The result shows that the Kobe River basin is a flood-prone area, with 77.46 percent of its land classified as less prone to flooding and 21.41 percent classified as flood-prone. However, only 21.41 percent of its land is classified as flood-prone. Only 1.13 percent of the land is protected from the danger of floods, compared to the whole country. The altitude factor is the most important element influencing flood susceptibility in Weda District, where the majority of the land (16.34 percent) is located at or below sea level, making it particularly vulnerable to flooding.
