Abstract
Kawasan pantai selatan Jawa, merupakan daerah pesisir yang berbatasan langsung dengan Samudera Hindia. Batas inilah yang secara langsung mempengaruhi karakteristik oseanografi di daerah pantai Selatan Jawa. Fenomena sedimentasi dari tahun ke tahun juga semakin besar, hal ini dibuktikan dengan berubahnya garis pantai di selatan Jawa, banyak pantai yang mengalami abrasi dan banyak juga yang mengalami akresi.
Penelitian ini bertujuan untuk mengetahui dampak dari proses abrasi dan sedimentasi di daerah pantai selatan Jawa berdasarkan pola sebaran arus yang terdapat di daerah penelitian. Model hidrodinamika digunakan untuk melakukan simulasi pola sebaran arus dan sebaran sedimen. Simulasi ini dilakukan pada dua bulan yaitu bulan Maret (mewakili curah hujan tertinggi) dan bulan Oktober (mewakili curah hujan terendah).
Dari hasil simulasi di area penelitian, pola arus yang terjadi di wilayah tersebut memiliki nilai kurang dari 6,921 m/s pada bulan Maret dan 7,60 m/s pada bulan Oktober. Besar konsentrasi sedimen tertinggi yang terjadi di sepanjang lokasi penelitian yaitu pada bulan Maret sebesar 6484,19 g/m3 dan pada bulan Oktober sebesar 2393,2 g/m3.

The southern coastal area of Java, is a coastal area directly adjacent to the Indian Ocean. This limit directly affects oceanographic characteristics in the southern coast of Java. Sedimentation phenomenon from year to year is also getting bigger, this is evidenced by the change of coastline in south Java, many coastal abrasion and many also experience accretion.
This study aims to determine the impact of abrasion and sedimentation processes in the southern coast of Java based on the current distribution pattern in the study area. Hydrodynamic model is used to simulate the pattern of current distribution and sediment distribution. This simulation was conducted on two months ie March (representing the highest rainfall) and October (representing the lowest rainfall).
From the simulation results in the research area, the current pattern in the area has a value less than 6.921 m / s in March and 7.60 m / s in October. The highest sediment concentrations occurring along the research sites were in March at 6484.19 g / m3 and in October at 2393.2 g / m3.
