Abstract

Kabupaten Subang sebagian besar mengalami pengalihanfungsian lahan menjadi tambak sejak empat hingga lima dekade terakhir. Dampak dari alihfungsi lahan tersebut dapat mengakibatkan hutan mangrove yang berkurang dan dapat terjadinya abrasi, banjir rob, sedimentasi, serta perubahan garis pantai. Penelitian ini bertujuan untuk menganalisis sebaran mangrove di pesisir Kabupaten Subang, mengevaluasi kerapatan kanopi mangrove di pesisir Kabupaten Subang, serta menganalisis uji akurasi metode Forest Canopy Desnity. Metode yang digunakan dalam penelitian ini adalah metode kuantitatif dengan penerapan metode Forest Canopy Density yang digunakan untuk menganalisis kerapatan kanopi mangrove pada citra dengan klasifikasi tiga kelas kerapatan yakni kelas kerapatan kanopi rendah, kerapatan kanopi sedang, dan kerapatan kanopi tinggi. Nilai FCD didapatkan dari empat indeks yakni Advanced Vegetation Index (AVI), Baresoil Index (BI), Shadow Index (SI), dan Thermal Index (TI). Berdasarkan pengolahan citra dalam penelitian ini didapatkan sebaran mangrove di pesisir Kabupaten Subang tersebar di empat kecamatan di wilayah pesisir yakni Kecamatan Pusakanagara, Kecamatan Legon Kulon, Kecamatan Sukasari, dan Kecamatan Blanakan, luas sebaran mangrove di Kabupaten Subang seluas ± 23,6565 km2. Rata-rata kerapatan mangrove di Kabupaten Subang berada di persentase 59% atau berada di kelas kerapatan sedang. Berdasarkan hasil uji akurasi menggunakan Kappa Coeffisient pada metode FCD memiliki nilai akurasi 86%, sehingga FCD dapat diterapkan untuk pemetaan kerapatan kanopi mangrove. Subang Regency has mostly experienced the conversion of land functions into ponds in the last four to five decades. The impact of land conversion can result in reduced mangrove forests and can lead to abrasion, tidal flooding, sedimentation, and shoreline changes. This study aims to analyze the distribution of mangroves on the coast of Subang Regency, evaluate the density of the mangrove canopy on the coast of Subang Regency, and analyze the accuracy of the Forest Canopy Desnity method. The method used in this study is a quantitative method with the application of the Forest Canopy Density method which is used to analyze the mangrove canopy density in the image with a classification of three density classes, namely low canopy density, medium canopy density, and high canopy density. FCD values are obtained from four indices, namely the Advanced Vegetation Index (AVI), Baresoil Index (BI), Shadow Index (SI), and Thermal Index (TI). Based on image processing in this study, the distribution of mangroves on the coast of Subang Regency was spread over four sub-districts in the coastal area, namely Pusakanagara District, Legon Kulon District, Sukasari District, and Blanakan District, the area of mangrove distribution in Subang Regency is ± 23,6565 km2. The average density of mangroves in Subang Regency is at a percentage of 59% or is in the medium density class. Based on the results of the accuracy test using the Kappa Coefficient, the FCD method has an accuracy value of 86%, so that FCD can be applied to mapping mangrove canopy density.
