Abstract

Perluasan wilayah urban dapat mencerminkan tingkat pertumbuhan ekonomi, pergerakan penduduk, dan konsumsi energi di suatu daerah. Namun perluasan wilayah urban juga dapat menimbulkan dampak negatif seperti penurunan kualitas lingkungan, hilangnya lahan pertanian, dan peningkatan emisi gas rumah kaca. Sebagai pusat kegiatan perekonomian dan pusat pemerintahan provinsi Jawa Timur, perkembangan urbanisasi di wilayah metropolitan GKS cenderung terjadi di sekitar pusat-pusat populasi yang ada, baik di sekitar kota Surabaya maupun pusat kota sekitarnya. Metode LULC merupakan metode yang umum digunakan untuk menentukan tutupan lahan. Namun cara-cara tersebut dapat menimbulkan kesalahan dalam identifikasi tipe penggunaan lahan tertentu, sehingga klasifikasi yang salah seperti lahan pertanian dianggap sebagai lahan perkotaan. Dalam penelitian ini digunakan analisis ENUI yang merupakan gabungan citra NTL, NDVI, NDWI dan NDBI untuk mengidentifikasi kawasan perkotaan. Dari uji akurasi diketahui nilai akurasi Kappa dengan ambang batas sebesar 2/3 nilai standar deviasi adalah sekitar 0,7 yang berarti analisis ENUI cukup akurat untuk mengidentifikasi wilayah perkotaan. Berdasarkan nilai dari analisis Annual Increase dan Urban Ratio, seluruh Kabupaten dan Kota di Kawasan Metropolitan Gerbangkertosusila mengalami pertumbuhan wilayah urban. Selain itu terjadi pergeseran titik ekspansi wilayah urban dimana pada jangka waktu 2017-2020 pertumbuhan wilayah urban berpusat di Kota dan Kabupaten Mojokerto dengan nilai Expansion Rate masing-masing sebesar 32,18% dan 9,97% serta nilai Annual Growth Rate masing masing sebesar 25,26% dan 9,11%. sedangkan pada tahun 2020-2023 bergeser ke Kabupaten Bangkalan di Pulau Madura dan Kabupaten Lamongan dengan nilai Expansion Rate masing masing sebesar 25,72% dan 15,74% serta nilai Annual Growth Rate masing masing sebesar 21% dan 13,76%.

Urban expansion can reflect the level of economic growth, population movement, and energy consumption in a region. However, urban expansion can also have negative impacts such as environmental degradation, loss of agricultural land, and increased greenhouse gas emissions. As the center of economic activity and the seat of government of the East Java province, the development of urbanization in the GKS metropolitan area tends to occur around existing population centers, both around the city of Surabaya and surrounding urban centers. The LULC method is a commonly used method for determining land cover. However, these methods can lead to errors in the identification of certain types of land use, so the wrong classification can cause agricultural land to be considered as urban land. In this study, ENUI analysis is used, which is a combination of NTL, NDVI, NDWI and NDBI images to identify urban areas. From the accuracy test, it is known that the Kappa accuracy value with a threshold of 2/3 standard deviation value is around 0.7, which means that the ENUI analysis is accurate enough to identify urban areas. Based on the value of the Annual Increase and Urban Ratio analysis, all regencies and cities in the Gerbangkertosusila Metropolitan Area experienced urban growth. In addition, there is a shift in the expansion point of urban areas where in the 2017-2020 period the growth of urban areas is centered in Mojokerto City and Regency with Expansion Rate values of 32.18% and 9.97% respectively and Annual Growth Rate values of 25.26% and 9.11% respectively. while in 2020-2023 it shifts to Bangkalan Regency on Madura Island and Lamongan Regency with Expansion Rate values of 25.72% and 15.74% respectively and Annual Growth Rate values of 21% and 13.76% respectively.
