Abstract

Meningkatnya jumlah penduduk akan menyebabkan konversi suatu lahan menjadi lahan terbangun demi memenuhi kebutuhannya. Hal ini menyebabkan terjadi pergeseran sifat pedesaan menjadi sifat perkotaan di suatu wilayah. Kota Depok yang juga terkena efek Jakarta Metropolitan Region mengalami fenomena tersebut mulai dari terbentuknya sampai tahun 2022. Oleh karena itu, tujuan dalam penelitian ini adalah mengidentifikasi perubahan tutupan lahan dan intensitas perluasannya dengan fokus lahan terbangun berbasis citra satelit Landsat 7 ETM + dan 8 OLI/TIRS dengan Google Earth Engine dari tahun 1999 dan 2022. Metode yang digunakan untuk melakukan klasifikasi adalah klasifikasi unsupervised dan untuk mengidentifikas intensitas perluasan dilakukan perhitungan Urban Expansion Intensity Index (UEII). Akurasi hasil klasifikasi unsupervised sebesar 0,65 dan 0,625 dari uji Kappa dapat digunakan untuk proses selanjutnya atau termasuk dalam kategori “good aggrement”. Hasil menunjukkan bahwa tutupan vegetasi menjadi tutupan lahan yang secara luas paling banyak menurun sebesar 5.918,9 Ha sedangkan lahan terbangun meningkat sekitar 8.807,4 Ha. Intensitas perluasan lahan terbangun di Kota Depok tahun 1999-2022 termasuk dalam kategori cepat. Selama 23 tahun, Kota Depok mengalami konversi lahan menjadi lahan terbangun secara drastis dengan intensitas yang cepat. Kesimpulan penelitian ini selama 23 tahun, Kota Depok mengalami perubahan tutupan lahan menjadi lahan terbangun terluas dan intensitas lahan terbangun dari perhitungan UEII adalah 1,91 yang tergolong cepat.
