Abstract

Pengamatan citra satelit untuk pemetaan mangrove di wilayah Pantai Indah Kapuk, Jakarta Utara pernah dilakukan pada tahun 2012. Sejak itu belum ada lagi informasi terbaru terkait hal tersebut. Oleh karena itu telah dilakukannya penelitian yang sama dengan menggunaka citra Landsat 7 dan citra Landsat 8 untuk mengetahui perubahan luas tutupan vegetasi mangrove di tahun 2010-2015. Metode klasifikasi citra untuk mengidentifikasi mangrove menggunakan klasifikasi terbimbing (supervised classification) Maximum Likelihood, selanjutnya dilakukan uji ketelitian citra dengan menggunakan matriks uji ketelitian yang mengacu pada Short (1982). Hasil penelitian menunjukkan selama kurun waktu tahun 2010-2015 terjadi pengurangan luas 38,79 ha (44%), penambahan 75,69 ha (87%) dan adanya daerah yang tetap 86,94 ha dengan akurasi ketelitian citra 85,71%. Observation using satellite image for mangrove mapping at Pantai Indah Kapuk, North Jakarta had already been conducted in 2012. Since then there had been no further information related toit. Therefore, the same research was done by using Landsat 7 and Landsat 8 to know the change of mangrove vegetation cover area in 2010-2015. Image classification methods for identifying mangrove used the supervised classification Maximum Likelihood, then tested the accuracy images by using a precision test matrix that refers to Short (1982). The results showed that during the period of 2010-2015 there was 38,79 ha (44%) of reduction area, 75,69 ha (87%) of additional area and 86,94 ha of fixed area with 85,71% accuracy.
