Abstract

Indonesia is an archipelagic country with a vast coastal area, so proper management is needed in the development of coastal areas. The city of Surabaya is one of the cities that carry out the development of coastal areas by projecting strategic areas of its coastal areas as regulated in the regional medium-term development plan 2016-2021. The strategic area of the coastal area of Surabaya city is divided into two, namely strategic areas to support economic growth and save the environment. One of the efforts to optimize the development of coastal areas is to examine changes in coastal morphology due to coastal utilization. Analysis of the study was carried out by comparing historical maps of the last 10 years with existing maps from google earth and map analysis using ArcGIS 10.8. The results show that most in the coastal area of north Surabaya there is a change in coastal morphology covering an area of 360,121 m2 as a result of the reclamation of the construction of the Lamong bay port and 623.12 m2 in the coastal area of east Surabaya due to the addition of mangroves. Regular monitoring and improvement efforts on the coast of Surabaya city must be carried out on an ongoing basis, so that coastal threats such as sedimentation and erosion can be minimized

Abstract

The Surabaya coast is a strategic area for sustainable development. For example, Teluk Lamong Harbor was built using reclamation. The port can be a solution but also has a coastal ecological impact. Therefore, a study of the coastline and distribution of the TSS was carried out around the Lamong Bay area. Based on the analysis of shoreline changes, the addition in the west (Kali Lamong) with NSM and EPR reached 166 m and 16.6 m/year and in the east, there was an addition (Osowilangon) with NSM and EPR reaching 337 m and 33.7 m/year. Based on TSS analysis by satellite, TSS in 2012 in the east had an average of 28.42 mg/L, increasing in 2017 to 36.39 mg/L, increasing again in 2022 with a value of 38.46 mg/L. While in the west in 2012, the high TSS had an average concentration of 40.95 mg/L, increasing in 2017 to 44.57 mg/L, increasing again in 2022 with a value of 52.68 mg/L. The modeling results show that the average TSS (west) in 2012 is ±20 mg/L, while in 2022 it is ±60 mg/L. In the east port, the average concentration of TSS in 2012 and 2022 did not change significantly (±20 mg/L).
