Abstract

SSC (Sediment Suspended Concentration) is the concentration of suspended sediment. This research was conducted in June 2018 in the Muara Sungai Padang area, Bandar Khalifah District, Serdang Bedagai Regency, North Sumatra Province. This research aims to describe the distribution of vertical and horizontal SSC suspended sediments and the factors that influence them in Padang river estuary  area, Bandar Khalifah District, North Sumatra Province. The method used in this research is the survey method and determining the location of sampling by purposive sampling. Measurement of water quality parameters is carried out in situ, namely temperature, salinity, pH, depth, current speed, and brightness. The results of the study of the distribution of suspended sediments in the waters of the Padang river can be concluded that the pattern of the distribution of suspended sediments when the tide moves towards the upper reaches of the river while at low tide moves towards the sea, namely the waters of the Malacca Strait which is influenced by currents. the largest suspended sediment concentration at tide to low tide is at the sampling point 1 which is 179 mg / l and recedes to pairs at sampling point 1 which is 121 mg / l.

Abstract

Penelitian ini dilaksanakan pada bulan Januari - Februari tahun 2017, di Desa PutikKecamatan Palmatak Kabupaten Kepulauan Anambas Provinsi Kepulauan Riau. Tujuanpenelitian ini adalah melihat pola arus dan pasang surut yang ditinjau dari fisikaoseanografi dan geomorfologi pantai, mengetahui pengaruh geomarfologi terhadaparus pantai daerah penelitian dan mendeskripsikan pola arus permukaan dipada saat airsedang naik pasang dan menuju surut. Metode yang digunakan adalah metode deskriptifyang bersifat eksploratif, metode purposive sampling yaitu penentuan lokasi untukpengambilan data, metode langrangian Pengukuran arus air. Hasil yang dapat disimpulkandari penelitian ini yaitu analisis bilangan formzahl diketahui bahwa tipe pasangsurut diperairan Desa Putik merupakan tipe pasang surut harian tungggal (diurnal tide)yang berarti dalam satu hari terjadi satu kali pasang dan satu kali surut dalam rentangwaktu 12 jam. Di perairan Desa Putik, pergerakan arus yang terjadi dipengaruhi olehpasang surut. Pola arus yang terjadi mengikuti perubahan pasang surut setiap harinya.Hutan mangrove yang berada dipulau mempengaruhi cepat dan lambat laju arus yangmasuk dan keluar. Kedalaman juga mengambil peran penting dalam pengaruh terhadapkecepatan arus daerah penelitian dimana semakin dangkal perairan maka arus yangmelewatinya semakin lambat, dan arus yang melewati perairan dalam dipengaruhi olehdensitas Berdasarkan analisis data dan Morfologi perairan daerah penelitian memberipengaruh yang sangat besar terhadap pola dan kecepatan arus.

Abstract

Foraminifera merupakan salah satu ordo dari protozoa yang bersel tunggal, hidup padalingkungan perairan terutama laut yang dapat dijadikan bioindikator kondisi lingkunganterumbu karang melalui indeks sederhana bernama FORAM Index. Penelitian inibertujuan untuk mengetahui tingkat kelayakan lingkungan terumbu karang berdasarkanforaminifera bentik dilihat dari nilai FORAM Index, Penelitian ini menggunakan metodesurvei pada pengambilan sampel sedimen dan pengukuran parameter lingkunganyang telah dilakukan pada bulan November 2016. Analisis foraminifera meliputi tahappreparasi sampel, kemudian sampel di jentik maksimal 300 individu, dengan dua kalipengulangan, sampel hasil penjentikan dikoleksi untuk identifikasi dengan melihatstruktur morfologi cangkang foraminifera. Hasil dari penelitian ini ditemukan 4 genusforaminifera bentik bioindikator kondisi perairan terumbu karang. Kondisi perairanterumbu karang di gugusan Pulau Pandan berdasarkan FORAM Index (FI) nilainyaberkisar antara 5,31 - 5,98, nilai ini memberi indikasi bahwa perairan sangat kondusifuntuk lingkungan pertumbuhan terumbu karang dicirikan oleh kehadiran Amphisteginanamun memperlihatkan kondisi lingkungan yang mulai menurun dan dicirikan olehkehadiran Quinqueloculina

Abstract

Klorofil-a merupakan salah satu parameter oseanografi penting yang menentukan kelimpahandan sebaran populasi ikan. Penelititian ini bertujuan untuk mengetahuidaerah penangkapan ikan dan kesesuaiannya dengan sebaran klorofil-a di perairan.Penelitian telah dilaksanakan di perairan Sungaitohor, Kabupaten Kepulauan Meranti.Metode yang digunakan adalah survey. Penentuan titik sampling menggunakan metodepurposive sampling. Pengambilan sampel di lapangan telah dilaksanakan pada bulanFebruari 2017 dan analisis klorofil-a di laboratorium pada bulan Maret 2017. Hasilpenelitian menunjukkan terdapat 4 titik daerah penangkapan ikan (DPI) di perairanSungaitohor. Konsentrasi klorofil-a di perairan berdasarkan analisis laboratorium berkisar0,878 - 7,356 μg/l dan berdasarkan analisis citra satelit Landsat 8 berkisar 0,806 –9,541 μg/l. Validasi terhadap kedua data menunjukkan hubungan yang sangat kuatdengan koefisien korelasi (r) = 0,8634 dan tidak berbeda secara siginifikan. Hasilpenelitian menunjukkan tingkat kesesuaian DPI terhadap sebaran klorofil-a adalahsebesar 75 %.

Abstract

Pasumpahan Island is an area that is affected by currents, waves and sedimentation processes because it is directly adjacent to the Indian Ocean and the mouth of the Pisang River, this causes changes in the coastline in the form of abrasion and accretion on the island. This study aims to determine the effect of currents, waves, and sedimentation processes on the rate of change of the shoreline for 10 years (1991-2001) on Pasumpahan Island. This research was conducted in March 2022 on Pasumpahan Island, Padang City, West Sumatra Province. The method used is a survey method to obtain primary data including current speed, heightwaves and sediments. The study method used is a quantitative method with a multi-temporal satellite imagery approachusing the Digital Shoreline Analysis System (DSAS) software with the End Point Rate (EPR) approach. The results of the analysis of current velocity values ​​ranged from 0.21-0.28 m/s, wave heights ranged from 0.24-0.55 m, the average diameter of the sediment ranged from 0.83-1 Φ. The results of image data processing show that there has been a change in the shoreline in the form of low category abrasion (0.4 m/year), stable (1.42 m/year), and accretion (3.07 m/year) on Pasumpahan Island.

Abstract

This research was carried out in December 2021-January 2022 in Dumai City District, Riau Province. The purpose of this study is to determine the rate of sea level rise based on analysis of tide data from 2001-2021 and to predict inundation areas in the next 20 years. This research method is a descriptive survey using remote sensing as an additional tool to show the results. Acquisition needs are in the form of primary data (land use and tide data) and secondary (slope data, elevation, land use, and tide data). These parameters are processed and analysed to describe the extent of the inundation by displaying a map of the City of Dumai. The results showed that the waters of Dumai City have a Formzhal number of 0.5, which means that the water area is classified as a mixed tide, semi-diurnal prevalence, with a sea level rise of 2.003 cm/year. Then, the numbers used to predict the height of sea level rise in the next 20 years are 0.973 m each. Furthermore, sea level height was analyzed to obtain the inundation area for the next 20 years, it turns out that the inundation area each year is 11.89 ha.
