Abstract

Indonesia merupakan negara maritim yang memiliki banyak pantai, akan tetapi banyak kecelakaan yang terjadi di pantai akibat dari arus rip. Kecelakaan akibat dari arus rip perlu perhatian khusus kepada masyarakat, sehingga munculah studi untuk mempelajari karakteristik arus rip dalam segi tipe, kecepatan, dan dimensi. Penelitian ini berfokus pada Pantai Klayar, Pacitan, Jawa Timur. Penelitian ini membandingkan kecepatan pada UAV dan pemodelan yang berlokasi di tanjung timur serta mencari tipe arus rip pada tanjung timur, selanjutnya adalah mencari arus rip di titik lain pada Pantai Klayar serta menganalisis kecepatan dan dimensi pada daerah tersebut. Pada tanjung timur kecepatan arus rip yang dianalisis berfokus pada jam 10:50 dan 11:40 dimana jam tersebut merupakan waktu saat survei injeksi uranine dilakukan. Selanjutnya penelitian ini, menginjeksi daerah tanjung barat dan tengah pada Pantai Klayar melalui pemodelan untuk dianalisis lebih lanjut mengenai tipe, dimensi, dan kecepatan rata-ratanya. Sehingga, hasilnya Pantai Klayar memiliki tiga jenis rip current berupa shadow rips, deflection rips, dan arus rip yang dipengaruhi oleh hidrodinamika dengan rata-rata arus rip paling besar berada di tanjung barat dengan hasil pada feeder rips sebesar 0.21 m/s dan pada neck sebesar 0.4 m/s. Hasil yang didapatkan juga rip current pada Pantai Klayar tidak memiliki head rips dikarenakan oleh pengaruh gelombang pecah dan rata-rata kecepatan rip current. Hasil dimensi rip current paling panjang dan lebar berlokasi di tanjung timur dengan panjang sebesar 89.5 m dan lebar sebesar 32.95 m.

Indonesia is a maritime country that has many beaches, but many accidents occur on the coast due to rip currents. Accidents which is caused by rip currents need to receive special attention from the public, so that a study has emerged to study the characteristics of rip currents in terms of type, velocity, and dimensions. This research focuses on Klayar Beach, Pacitan, East Java. This study compares the speed of UAVs and modeling located in the east headline and looks for rip types in the east headline, then looks for rip currents at other points on Klayar Beach and analyzes the velocity and dimensions in that area. At the east headline the rip current analyzes of rip current focuses on 10:50 and 11:40 which is the time when monitoring of uranine injection is carried out. Furthermore, this research injects the western headline and central of the beach on Klayar Beach through modeling for further analysis regarding the type, dimensions, and average velocity. So that the result is that Klayar Beach has three types of rip currents in the form of shadow rips, deflection rips, and rip currents which are influenced by hydrodynamics with the largest average rip currents being in the western headline with the average of feeder rips is 0.21 m/s and neck rips is 0.4 m/s. The results obtained also show that rip currents at Klayar Beach do not have head rips due to the influence of breaking waves and the average velocity of rip currents. The results of the longest and widest rip current dimensions are located on the east headline with a length of 89.5 m and a width of 32.95 m.
