Abstract

Rebon beach, batang regency, it is located between 6°56'1" LS and 6°54'32, 67" LS Rebon beach fish dropping is hardly ever can be used efficiently because there is a sediment from 2 big river that block the sailing route, and the possibility of development of dock for fish dropping in Rebon beach. For that reason, researchis should be done to know the effect of sedimentation in Boyo and Urang river, to check whether The disturbing sediment can be used as road material. Research also should take the oceanography physics data wich can be used as a basic data for developing the dock in Rebon beach. Research methodology which was used was the explorative way that examined in certain time and place. It took data field such as fundamental sediment, solid material suspensed, direction and velocity of sea wave, wave, salinity, brightness, temperature, rise and fall, depthness, these data were analyzed using laboratory way: distribution of grain size grain shape, mineral kind, percentage of magnetic mineral, percentage of certain mineral, specific gravity, carbonat, organic matter. We process all of these data and the result is there are 14 station which the sediment material can be used as filler, a material road. The 14 station number 1, 19, 22, 25, 25, 26, 29, 30, 32, 38, 39, 40, 41, and 42. From the static analysis " measuring the minimum angle of sub vector space" that used incalculating the 20 factor, the result is the influence of Urang beach is very significant to Rebon beach waterworks. From the data such as current magnetic mineral map, depthness map, skewness map, and mean, we can see the influence of Urang beach waterworks to Rebon beach waterworks. From the statistic calculation "measuring the minimum angle of sub vector space" we know that the Boyo river is 47,9412°, Urang river is 28,1458° and Rebon beach waterworks 27,3747° , the vicinity of Boyong river and Urang river and Urang river 0,7711°, we can say the Urang beach has big responsibility in Rebon beach sedimentation. Depthness map, wave, etc support the statistic calculation. From the research that has been done, data were supporting each other, we can say that the purpose of the research is accomplished, that is generally there is possibility fisherman can use the disturbing sediment in dry season.This research was done in June when the east monsoon wind blows. We still have to do research in January when the west monsoon wind blows so we can have more accurate data. In a couple of month of researching we can use the data as fundamental planning data Pantai Rebon Kabupaten Batang yang terletak pada 6° 54' 1" LS dan 6°54'32,67 'BT adalah lokasi tempat pendaratan iikan yang cukup representatif karena ditempat tersebut ada 2 (dua) bangunan pelelangan ikan dan tempat kapal nelayan berlabuh. Walaupun ditepi laut tetapi air sumur dangkal masih mengeluarkan air tawar sehingga sangat mendukung adanya Tempat pelelangan Wan (TP1) dilokasi tersebut ,sehingga sebelah barat sungai bangunan TPI akan diperbesar. Muara sungai Boyo adalah satu diantara sungai yang bermuara di pantai Rebon yang flap tahun mengalami sedimentasi yang mengganggu aktivitas pendaratan kapal nelayan ,penulis meneliti sedimen yang mengganggu tersebut untuk bisa dimanfaatkan. Hasil penelitian menggunakan standart ASTM dan Standart penbuatan jalan Bina Marga 1972. menunjukkan sedimen di pantai Rebon dapat digunakan sebagai filler bahan jalan. Perhitungan statistik dengan vector sudut minimum menghasilkan bahwa perairan Pantai Rebon sangat dipengaruhi oleh sungai Urang. Pengaruh sungai Boyo, sungai Urang terhadap sifat sedimen di perairan Rebon sehingga data tersebut dapat dipakai dalam perencanaan, sedangkan data Oseanagrafi antara lain arcs laut , kecepatannya, MPT, Salinitas, KandunganKarbonat, kandtmgan zat Organik, persentasi mineral magnetik dan non magnetik, jenis mineral dan persentasinya bentuk mineral dapat digunakan sebagai data pendukung perencanaan pembuatan Break water.
