Abstract

Pekalongan City consistently experiences annual floods. In this research, we aimed to map the distribution of potential flood inundation in Pekalongan City under two scenarios: the existing land cover and urban planning (Rencana Tata Ruang Wilayah/RTRW). We utilized hydrological modeling to assess the suitability of the RTRW for future implementation. The Soil Conservation Service – Curve Number (SCS-CN) method was employed, incorporating Digital Elevation Model (DEM) data, soil data, precipitation data, and two sets of land cover data (existing and urban planning). The findings indicate that under the existing land cover, approximately 13.97% of the area is susceptible to flooding, while the remaining 86.03% is not at risk. Conversely, the model using the urban planning (RTRW) scenario suggests that 14.06% of the area has the potential to flood, while 85.94% is not susceptible to flooding. The increase in potential flooding in the urban planning scenario may be attributed to the expansion of residential areas and the reduction of plantation and dry land cover. Furthermore, in assessing monthly modeling results, we observed that the area with flood potential is highest in December 2022 and lowest in June 2022. Considering topographical conditions (DEM), we found that the potential for flood inundation is fairly and evenly distributed in flat areas, mostly with elevations of less than 11 meters. Areas at higher elevations are predominantly free from flood potential, but it is noteworthy that certain areas in the Pekalongan Selatan District, with elevations higher than 11 meters, still have the potential for flooding.  Keywords: Flood, hydrology model, SCS-CN, existing land cover, urban planning

Abstract

Tol Laut is a marine activity that manages the maritime highway system in Indonesia to ensure and improve connectivity within the national logistics and supply chain system. This system arises because of the inequality of economic growth and development between several regions and provinces. The purpose of this program is to reduce high price disparities so that equity across regions can be achieved. However, this system has not run optimally. The performance of the program, which has entered its eighth year, is still less than 30%. Many problems arise that persist in causing the high price of goods. Hence, this study will identify the causes of the suboptimal Tol Laut by using spatial and geographic approaches on a sample of T-3 shipping route. Based on the spatial approach, it is found that the route is not optimal, so a strategy is obtained to create a new optimal route by producing a more efficient distance of 51,148 nm and a more effective time of 2 hours 18 minutes. Based on the geographical approach, the economic, social, and cultural factors that influence it were obtained. The identification of economic factors shows that high insurance premiums cause price disparities. Through this research, a strategy to produce more efficient and effective tariffs is obtained so as to reduce high disparities. This is important because Tol Laut is national strategic project that needs to be maintained.Received: 2024-04-30 Revised: 2025-08-15 Accepted: 2025-12-03 Published: 2025-12-04
