Daftar Isi:
- Sedimentation is the deposition of rock material that has been transported by water or wind. Majene is one of the areas in Indonesia which is mostly a coastal area so it is necessary to research the sedimentation rate. The sediment rate was determined using an assembled device made of 4 m iron and a 25 cm long 2-inch pipe tied to the iron. The measurement location consists of 3 locations. The first location is located at the western end of Barane beach, the second location is in the middle and the third location is located at the eastern end of Barane Beach which is close to the river mouth. The sediment height measurement in the pipe was carried out every week for each location for 3 measurements. From the research results, the sedimentation rate at location 1 ranged from 14,788.36-23,238.85 cm3/year with average sedimentation of 18,661.5 cm3/year. The sedimentation rate for location 2 ranged from 12,675.73-21,654.38 cm3/year with an average sedimentation of 16,724.92 cm3/year. The sedimentation rate for location 3 ranges from 13732.04-16900.98 cm3/year with average sedimentation of 15,562.98 cm3/year. Ocean currents carry sediment towards the western end of the Barane coast so that the largest sedimentation rate is at the first location.
- Sedimentasi adalah pengendapan material batuan yang telah diangkut oleh air atau angin. Majene adalah salah satu daerah di Indonesia yang sebagian besar merupakan wilayah pesisir sehingga perlu dilakukan penelitian tentang laju sedimentasi. Penentuan laju sedimen menggunakan perangkat rakitan yang terbuat dari besi 4 m dan pipa 2 inch sepanjang 25 cm yang diikat ke besi. Lokasi pengukuran terdiri dari 3 lokasi. Lokasi pertama terletak di ujung barat pantai barane, lokasi kedua terletak di tengah dan lokasi ketiga terletak di ujung timur pantai barane yang dekat dengan muara sungai. Pengukuran ketinggian sedimen dalam pipa dilakukan setiap minggu untuk setiap lokasi selama 3 kali pengukuran. Dari hasil penelitian, laju sedimentasi di lokasi 1 berkisar antara 14,788.36-23.238,85 cm3/tahun dengan sedimentasi rata-rata 18.661.5 cm3/tahun. Laju sedimentasi untuk lokasi 2 berkisar antara 12.675.73-21.654.38 cm3/tahun dengan sedimentasi rata-rata 16.724.92 cm3/tahun. Laju sedimentasi untuk lokasi 3 berkisar antara 13732.04-16900.98 cm3/tahun dengan sedimentasi rata-rata 15.562.98 cm3/tahun. Arus laut membawa sedimen ke arah ujung barat pantai barane sehingga laju sedimentasi terbesar terdapat di lokasi pertama.Kata Kunci: Sedimentasi, Arus Laut, Pantai Barane.
