Kabupaten Indramayu merupakan salah satu wilayah pesisir yang berada di Jawa Barat, salah, salah satu ekosistem yang berada di daerah tersebut yaitu ekosistem mangrove. Kerusakan ekosistem mangrove di Kabupaten Indramayu menyebabkan intrusi air laut ke daratan. Perbedaan tingkat kerapatan mangrove di beberapa pantai mengakibatkan perbedaan jarak intrusi air laut ke daratan. Penelitian berjudul “Analisis Hubungan Kerapatan Antara Kerapatan Mangrove dengan Potensi Intrusi di Pesisir Indramayu Jawa Barat” bertujuan untuk mengetahui tingkat kerapatan mangrove, jarak intrusi dan hubungan kerapatan mangrove dengan jarak intrusi. Penelitian dilaksanakan bulan Mei 2016. Metode penelitian adalah metode survey dengan tekhnik pengambilan sampel stratified sampling. Analisis data dilakukan secara deskriptif komparatif, uji F (ANOVA), uji korelasi dan regresi. Hasil penelitian di Kabupaten Indramayu menunjukkan adanya pengaruh kerapatan mangrove terhadap intrusi. Pada daerah yang memiliki mangrove dengan kerapatan rendah memiliki tingkat intrusi yang lebih tinggi dibandingkan dengan  kerapatan mangrove tinggi dan daerah yang tidak memiliki ekosistem mangrove merupakan daerah dengan tingkat intrusi tertinggi. Faktor penyebab perbedaan tingkat intrusi yaitu kerapatan mangrove, jarak sumur dari pantai, kedalaman air sumur dan tekstur tanah. Berdasarkan uji korelasi kerapatan mangrove dengan jarak intrusi air laut memiliki hubungan yang cukup (-0,402) yang artinya semakin tinggi kerapaatan mangrove maka tingkat intrusi akan semakin rendah.

Indramayu regency is one of the coastal areas in West Java, one of the ecosystems that are in the area is the mangrove ecosystem. Damage to the mangrove ecosystem in Indramayu has causing intrusion of seawater into the mainland. Differences in density in some coastal mangrove resulted in seawater intrusion distance difference to the mainland. The study entitled "Analysis of Relationship between Density Mangrove with Potential Intrusion in Coastal Indramayu West Java" aims to determine the density of the mangrove, the distance of intrusion and mangrove density in correlation with distance of intrusion. The research was conducted in May 2016. The research method used survey method with stratified sampling technique. The data were analyzed descriptively comparative F test (ANOVA), correlation and regression. The results of the research in Indramayu showed there was influence of distance toward the intrusion. In the mangrove areas with lower density has a higher level of intrusion than the mangrove with higher density whilst, areas which has no mangrove ecosystem is an area with the highest level of intrusion. Factors which causing the differences in the level of intrusion are mangrove density, distance from shore wells, the depth of the well water and soil texture. Based on the correlation test mangrove density with distance seawater intrusion have enough relationship (-0.402), which means that the higher density of mangrove the level of intrusion mangrove would be lower.
