Analysis of Residential and Industrial Land Development and Its Influencing Factors in Semarang City in 2011 and 2022

Abstract

Settlements are part of the environment inhabited by humans, comprising supporting infrastructure facilities in urban and rural areas. Land developments include residential developments and industrial areas. One of the factors that cause the development of built land in urban areas is an increase in the number of people, both naturally (internal) and through population migration (external). Semarang is a city in Central Java province that is the center of government, education, and economy. Due to these factors, Semarang's population has grown, which has led to an increase in the amount of built-up land within the city. Each Semarang City subdistrict's 2011 and 2022 data, as well as Landsat images 5 and 8, were used in this study. This study employed quantitative methods and multiple linear regression, overlay, and maximum likelihood classification analysis as data analysis techniques. The study's findings are the degree of development of the built-up land in each subdistrict of Semarang city in 2022, with a total land development area of 5653.86 ha. The highest levels of development were in Genuk Subdistrict, Mijen Subdistrict, and Ngaliyan Subdistrict. The results of multiple linear regression showed R2 values of 0.821, indicating that topographic averages and free variables (such as population density, population, public facilities, and the difference in population density between 2021 and 2011) had an influence of 82.1% on the development of built-up land in Semarang city in 2022.
