Determining the Spatial Connectivity of Surabaya’s Peri-urban Area towards Urban Rural Linkage Framework Based on Population Movement Relation

Abstract

The rapid development and becoming the most dominant growing center at East Java Province, Surabaya City is affected by its periphery areas. This fact is shown by the core area act as an economic center and the periphery act as a settlement support, resulting in urban area widening, known as peri-urban area. This also indicate a domination of periphery area movement toward the core area in the form of people’s flow or population movement. However, the result of the observation shows a tendency of peri-urban problem occurrences such as traffic jam, flood, and slum area. Thus, it is necessary to determine its connectivity between the core area and its support area in urban-rural linkage framework for the aim of having a formulated anticipation effort to face those problems in the future. The analysis was done by quantitative and qualitative approach resulting Normalized Difference Built-Up Index (NDBI) of the year 2002 until 2018 which the conversion reach out 43,95% of non-built-up area to build up area due of the urban area widening. Also, the spatial interaction from the Gravity Model shows the strongest interaction force occurred at Sidoarjo Regency’s districts which directly adjacent with Surabaya City. It can be concluded that the peri-urban area at southern Surabaya have a significant urban rural linkage interaction strength from the population movement. This imply that prioritizing the infrastructure development is a step forward to solve the occurred problems. With a hope by understanding these facts will encourage the government to formulate the sectoral policies.
