Abstract:

Pasir merupakan sesuatu penomena yang menarik karena padanya tersimpan misteri bagaimana partikel itu terendapkan sesuai dengan lingkungannya, apakah merupakan pasir pada lingkungan marin, pantai atau sungai. Untuk mengetahui lingkungan pengendapan tersebut maka dilakukan identifikasi karakteristik pasirnya. Metoda penelitan meliputi pengambilan contoh, analisis besar butir, klasifikasi nomenklatur sedimen dan parameter statistik. Klasifikasi nomenklatur sedimen pada endapan sedimen permukaan dasar laut, gisik pasir, tanggul gisik dan endapan sungai aktif didapat pasir sebanyak, masing masing

Research on zinc levels in sediments has been widely practiced, but fractionation and distribution of zinc attachment in Blue Spring sediment using BCR Sonification. The results of the zinc analysis using BCR Sonification method gave precision value of 0.49 percent, and accuracy of 91.20 percent, the results showed that BCR method has high precision and accuracy value.

Coastal areas have the potential to be developed and utilized for various purposes. However, the intensity of coastal use can result in the degradation of the coastal environment. Therefore, management of the coastal areas is often carried out by building shore protective structures, including groynes. The placement of a structure in the form of a groynes is primarily intended to block littoral flow in moving sediment out of certain places in the shore. Therefore, the placement of groynes on the shore needs to be followed by a study to find out the effectiveness of the groynes. The effectivene
