Abstract

Perairan laut di sisi selatan pulau Jawa Timur mempunyai karakteristik dengan topografi dasar laut yang curam, dan gelombang besar, serta berbatasan langsung dengan Samudera Hindia. Sedangkan perairan Int di sisi utara pulau Jawa Tirnur memiliki karakteristik dengan kondisi topografi dasar laut yang lumayan landai dan bergelombang relatif kecil serta berbatasan langsung dengan lain Jawa. Perbedaan dua karakter ini merupakan hal yang menarik untuk diamati, terutama Muka Air Lain Rerata (MLR). Metode admiralty adalah metode perhitungan pasang surut yang digunakan untuk menghitung dua konstanta harmonik yaitu amplitudo dan kelarnbatan phasa. Perhitungan dengan cara admiralty diperoleh konstanta harmonik yang akan dilanjutkan dengan analisa data dengan menggunakan bilangan Formzahl yakni pembagian antara amplitudo konstanta pasang surut harian utama dengan amplitudo konstanta pasang surut ganda utama. Hasil perhitungan bilangan Formzahl ini akan diketahui tipe pasang surut di perairan Perak Surabaya dan perairan Prigi Trenggalek.Perbandingan tipe pasang surut di perairan utara Jawa (Perak Surabaya) dengan perairan selatan Jawa (Trenggalek) menggunakan bilangan Formzahl tidak menunjukkan perbedaan, berdasarkan penelitian ini maka diperoleh tipe pasang surut antara perairan perak surabaya dengan perairan prigi Trenggalek berkisar antara 0.26-1.5 maka tipe pasang surut antara kedua perairan ini adalah tipe pasang surut campuran condong ke harian ganda. Perbandingan fluktuasi Muka Laut Rata-rata (MLR) di perairan utara Jawa Timur (Perak Surabaya) dengan perairan selatan Jawa Timur (Trenggalek) berdasarkan uji analisa Mann Whitney U-Test diperoleh P0.05 maka dapat disimpulkan bahwa nilai MLR di dua lokasi adalah sama nyata, dan berdasarkan hasil penelitian yang telah dilakukan dengan menggunakan metode admiralty, fluktuasi Muka Air Laut Rerata (MLR) di perairan Perak Surabaya rata-rata 1237.76 mm sedangkan rata-rata Muka Air Rerata (MLR) di perairan Prigi Trenggalek berkisar antara 1158.3 mm.Kata kunci: Pasang Surut, Admiralty, Mann Whitney U-Test

Abstract

Fenomena dan dinamika di perairan laut menjadi salah satu hal penting yang harus dipertimbangkan dalam berbagai aktifitas yang dilakukan dilingkungan perairan laut. Pergerakan massa air laut dinamis sepanjang waktu memberikan pengaruh terhadap dinamika perairan. Angin menjadi salah satu parameter penting yang berpengaruh terhadap fenomena dan dinamika perairan laut. Beberapa parameter oseanografi yang dipengaruhi oleh angin adalah arus dan gelombang. Parameter lainnya yaitu pasang surut, yang dipengaruhi oleh letak bulan dan matahari menjadikan dinamika lautan semakin kompleks. Arus, gelombang, dan pasang surut diduga berpangaruh signifikan terhadap kompleksitas di lautan. Tujuan dari penelitian ini adalah untuk mengkaji karakteristik parameter oseanografi di perairan Selat Madura, Kabupaten Bangkalan. Data utama penelitian berupa data arus, pasang surut, dan gelombang. Data pasang surut diperoleh dari BMKG Perak, Surabaya. Data yang digunakan adalah data bulan September 2012. Data arus dan gelombang diolah secara deskriptif untuk mengetahui dominasi arah dan kecepatan, sedangkan data pasut diolah menggunakan metode Admiralty untuk mengetahui tipe pasang surut perairan. Hasil analisa menunjukkan kisaran arus relatif kecil (0,28-3.54 cm/detik) dengan arah Timur laut, Timur dan Tenggara. Karakteristik gelombang menunjukkan kecenderungan semakin besar pada setiap minggunya dengan pola harian cenderung stabil sepanjang hari. Tipe pasang surut campuran condong ke harian ganda.Kata Kunci: hidrooseanografi, total suspended solid (TSS) STUDY OF OCEANOGRAPHYC PARAMETERS IN THE MADURA STRAIT WATERS OF BANGKALAN DISTRICTABSTRACTPhenomenon and the dynamics in marine waters become important to be considered in some activities. The movement of sea water mass is dynamic along the time which gives influence toward waters dynamics. Wind become one of the important parameters influenced the phenomenon and sea waters dynamics. Some oceanography parameters were influenced by wind is flow and wave.  Other parameter is riptide, which is influenced by the position of moon and sun being sea dynamics is more complex. Flows, waves, and riptide are estimated significantly have an effect on the ocean complexity. This study aims to review the characteristics of oceanography parameters in Madura Trait waters. The main data of this research are flows, riptide, and wave data. The riptide data (September 2012) was gained from BMKG Perak, Surabaya. Flows and wave data were processed as descriptive data to know the domination of direction and velocity, while riptide data was processed by using Admiralty method to know the kind of waters riptide. The results show that whirl-flows are small (0,28-3.54 cm/second) turned to northeast, east and southeast. The characteristic of wave shows more and bigger in each week but it is stable in each day. The type of mixed riptide tends to the kind of multiple daily.Keywords: hydro-oceanography, total suspended solid (TSS)

Abstract

Objective of this study was to determine reproductive performance of A. philippiana. Samples were collected from the oil affected mangrove mudflat in Pototan, Guimaras, Philippine on September 2007. A. philippiana were induced to spawn using the serotonin method. Only A. philippiana with shell length of approximately 4.0-5.5 cm were induced to spawn. Three pairs of one ripe female and one ripe male were chosen and placed in aquaria with 3 replicates. A 0.3 ml of 4 rnM serotonin solution (Gros et al., 1997) was injected into 1-2 mm of the gonad of both male and female clams using 0.65 x 25-mm bore hypodermic needle attached to a 5 ml plastic syringe during mid until late afternoon. Number of spawned eggs was calculated, and fertilization was conducted. At 47 h, the percentage of normal (D-larvae) veliger relative to the initial number of eggs was calculated (Massapina et aL, 1999). Larvae from each spawner were reared separately in aquaria for several days without feeding in order to estimate survival rates. The number of larvae we re-estimated every 24-h intervals until total mortality. The decrease in the number of larvae per container we re-calculated as the proportion of live larvae from the initial number of larvae (extinction rate) (Narvarte and Pascual, 2003). Result of this study are total Total spawned eggs (x10 (g m) is 86.11±3.80, Fertilization rate (%) is 83.01±3.13, and harching rate is 36.51+8.64, Length of newly hatched larvae (gm) is 135.73±1.96, Number of days to total mortality (after hatching) without feeding is 9-10 days.Keywords: reproductive, Anodotia philippiana
