Abstract

                                                                                Pantai Slamaran merupakan salah satu pantai wisata di Kota Pekalongan yang memiliki tingkat sedimentasi cukup tinggi dimana terdapat muara sungai sudetan sungai Banger dan muara sungai Slamaran yang membawa material – material dari darat ke laut. Material tersebut ada yang bersifat terlarut dan tersuspensi. Peneltian ini bertujuan untuk mengetahui karakteristik arus, mengetahui nilai MPT saat pasang menuju surut dan saat surut menuju pasang pada kedalaman 0,2d, 0,6d, dan 0,8d dan pengaruh arus terhadap sebaran muatan padatan tersuspensi di Pantai Slamaran. Metode penelitian yang digunakan yaitu metode kuantitatif sedangkan penentuan lokasi pengambilan sampel sedimen menggunakan metode sampling purposive. Model matematik yang digunakan adalah model ADCIRC untuk pola arus dan ArcGis untuk sebaran MPT. Arus yang berperan pada lapisan permukaan, tengah, dan dasar adalah arus nonpasut seperti longshore current. Pada lapisan permukaan arah arus dominan ke utara dan ke tenggara, pada lapisan tengah arah arus dominan ke barat laut dan ke timur dan pada lapisan dasar arah arus dominan ke barat laut dan ke tenggara. Sebaran MPT di pantai Slamaran dipengaruhi oleh arus non pasut seperti longshore current. Pada saat pasang menuju surut nilai MPT pada kedalaman 0,2d 500 mg/L – 952 mg/L, pada kedalaman 0,6d 467 mg/L – 927 mg/L, dan pada kedalaman 0,8d 470 mg/L – 906 mg/L. Pada saat surut menuju pasang nilai MPT pada kedalaman 0,2d 952 mg/L – 1063 mg/L, pada kedalaman 0,6d 927 mg/L – 1039 mg/L, dan pada kedalaman 0,8d 1157 mg/L – 2031 mg/L.

Abstract

The purpose of this research was to determine the correlation between the weight of the ovary, the number of follicles, and the quality of the oocytes from the culling female bovine   obtained from the slaughterhouse. The variation may affect the potential of the ovary to produce follicles. Paired ovaries were obtained from female bovines.  Follicle numbers were recorded and divided into three size categories (small: 3 mm, medium: < 3 mm-8 mm, and large: > 8 mm). Oocytes were aspirated and the number of oocytes was recorded and graded into four categories (grades A, B, C, and D). There was a positive correlation between the weight of the ovary and the number of follicles, which is 0.560 with the regression equation y = 3.52 + 0.501 x. There was a positive correlation between the number of follicles and the number of oocytes, which is 0.546 with the regression equation y =2.48 + 1.204 x. There was a positive correlation between the number of oocytes and the grade of oocytes, which is 0.520, with the regression equation y = 0.93 + 0.800 x. There was no correlation between the weight of the ovary and oocyte grade A, which is 0.013.
