Abstract

Land subsidence is a natural phenomenon that occurs due to changes in the position of an object in the vertical direction. There are several factors that cause this phenomenon, including excessive use of ground water, heavy surface loads, and changes in land cover that are not in accordance with the carrying capacity and carrying capacity of the soil. Considering the importance of this phenomenon to human life in general, and infrastructure in particular, regular monitoring must be carried out to determine the magnitude of land subsidence. Monitoring the occurrence of land subsidence can be done using the DINSAR method. This method uses phase differences in remote sensing images from the Sentinel 1 satellite to determine changes in the height of a location from two image data collection times. Data processing with GIS support can be carried out to obtain differences in displacement or movement of the ground surface during the two data collection times. Measuring land subsidence value in the Pantura area uses image data from January 2022 to January 2023. From this research, the maximum value of land subsidence is 2.5 cm in 1 month, 5 cm in 3 months, and 7.5 cm in 1 year. The linear function of land subsidence [y] according the data is y = 4.8058t + 2.8641, where t is the time parameter. With this function, the estimated land subsidence of Pantura Kota Semarang in two years is 12.48 cm.

Abstract

Tanah Longsor merupakan salah satu bencana yang terjadi di Indonesia. Ada beberapa factor penyebab terjadinya tanah longsor antara lain curah hujan tinggi, jenis tanah, bencana alam pemicu dan kondisi kemiringan tanah. Untuk melakukan analisis dalam ruang lingkup sempit penyebab yang paling berpengaruh adalah kemiringan tanah. Hal ini disebabkan untuk ruang lingkup local curah hujan dan jenis tanah relatif sama, sehingga dapat disamakan pengaruhnya. Kecamatan Gunungpati merupakan salah satu kecamatan di Kota Semarang. Secara topografi Kecamatan Gunungpati 18.92 % di Ketinggian 19–150 meter, 30.11% di Ketinggian 150–240 meter, 27.78% di ketinggian 240–320 meter, 18% di ketinggian 320 – 440 meter, dan 5.2% di ketinggian 440-610 meter. Analisis spasial dilakukan terhadap data citra DEMNAS BIG untuk mendapatkan peta ketinggian dan peta tingkat kelerengan. Analisis spasial yang dilakukan dengan menghitung tingkat kelerengan pada setiap ruas area. Perhitungan kelerengan dilakukan dengan menghitung persentase perbandingan beda tinggi dan beda jarak datar. Hasil perhitungan kelerengan digunakan untuk pengelompokan tingkat kelerengan yaitu datar, landai, agak curam, curam, dan sangat curam. Analisis dilakukan tiap desa untuk mengetahui persentase masing-masing ketinggian dan tingkat kelerengan. Berdasarkan analisis spasial intersect didapatkan hasil daerah di Kecamatan Gunungpati yang rawan terjadinya longsor terletak pada kondisi kelerengan agak curam, curam, dan sangat curam. Total kawasan rawan tanah longsor berdasarkan skema tersebut adalah 2067.83 Ha atau 38.40 % dari total luas daerah Kecamatan Gunungpati yaitu 5834.47 Ha
