Abstract

This study was conducted from  November 2017 in Rupat Strait, Riau Province. The analysis of model was done in Laboratorium of Physical Oceanography, Departement of  Marine Science, Faculty of Fisheries and Marine, University of Riau. The research aims to understand the wave and tidal current on high tide (spring tide condition) in Rupat Strait. The significant wave height is about 0.12-0.90 m/s. The current speed  is about 0.18-0.78 m/s. The result of the study indicate that at spring tide condition, the tidal current from Malaka Strait flows up to Rupat Strait by northern and eastern part of Rupat Strait. This condition  influences distribution of sediments in Rupat Strait the cause of the changes coastline

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 dilakukan pada bulan Oktober 2018 di Perairan Pantai Rangsang Barat, Kabupaten Kepulauan Meranti, Provinsi Riau. Penelitian ini bertujuan untuk mengetahui perubahan garis pantai yang  terjadi di Kecamatan Rangsang Barat dalam rentang waktu 10 tahun terakhir dan implementasi hukum laut tentang pengaturan permasalahan perubahan garis pantai di Kecamatan Rangsang Barat Kabupaten Kepulauan Meranti Provinsi Riau. Hasil pengolahan citra Landsat 5 dan Landsat 8 dengan besar Perubahan garis pantai di Desa Melai adalah 55,56 m (akresi), di Desa Kedabu Rapat sebanyak 50,94 m (abrasi) dan di Desa Bungur sebesar 42,10 m (abrasi). Implementasi hukum laut menurut pasal 15 UNCLOS 1982 dalam penetapan wilayah laut teritorial yang berdampingan dengan negara lain memutuskan uu no 2 tahun 1971 tentang penetapan batas wilayah kedua negara di Selat Malaka. Penentuan titik koordinat tersebut ditetapkan berdasarkan Garis Pangkal masing-masing negara. Dengan diberlakukannya Konvensi Hukum Laut Internasional 1982 sehingga ditetapkan Peraturan pemerintah Republik Indonesia no 38 tahun 2002 tentang daftar koordinat geografis titik-titik garis pangkal kepulauan Indonesia. Dengan penetapan titik koordinat geografis permasalahan pada perubahan garis pantai negara Indonesia dan Malaysia akibat dari abrasi dan akresi dapat diselasaikan dengan memperhatikan titik koordinat geografis pada pulau Rangsang.

Abstract

This reseach was conducted in March to April 2012, in Padang Beach ofWest Sumatra and in Integrated Oceanology Lab of Riau University. The aim ofthis research is to reveal the progress of abration happening in Padang Beach. Themethod used in this research is the survey one. The result of this reasearch showsthat abration happened at three research stations, the abration velocity at the firststation is 0,28 m/year, the second is 0,36 m/year and at the third one is 0,12m/year. The principle causes of abration process in Padang beach are the flow andthe great wave of the sea which signed by each characteristic and the flow that thebeach abrased easily, as the bigger of wave's energy and water's flow the faster ofabration will be.

Abstract

The stratigraphy of bottom sediments was investigated in eastern waters of RupatStrait, Riau Province in June 2013. The analysis of sediment were conducted by twomethods i.e : grain-size analysis and ignition loss methods. The result showed that thevertical characteristic of bottom sediments changed irregularly. The vertical character-istic change of sediments was represented by the grain-size distribution, both verticallyand horizontally in the area. The similiarity of sediment characteristic among the sta-tions also represented by a cluster analysis. The cluster analysis showed that the sedi-ments were divided into four clusters which showed clearly the different of sedimentcharacteristic between station in this area.

Abstract

The research was conducted in June 2013 in Rupat Starait waters with the aim to deter-mine the constituent materials in the sediment. The Eckman Grab was used to take samples and than the sediment was analyzed to determine the composition and content of organic mat-ter. The results showed that the composition of the sediment composed of lithogenous and biogenous. Lithogenous composition especially in waters and rocks dominating presence even-ly at each station. The highest composition found in a location close to the mainland and one of the areas that get the first time the influence of the tide, from the Strait of Malacca and the flow from Strait of Bengkalis. Lithogenous lowest percentage was found in areas close to the mangrove area whre the station had high composition of litter biogenous. While the station containing the lowest organic matter was the station near the strait of Malacca. Mean while the station closed masjid river and Dumai river containing organic matter was high due to the flow of the river carrying a high content of organic materials.

Abstract

Penelitian ini dilakukan pada bulan Maret-April 2019 di Perairan Tanjung Balai Asahan Provinsi Sumatera Utara. Bertujuan untuk mengetahui ukuran partikel sedimen, mengetahui kelimpahan dan pola sebaran kerang darah (A. granosa), serta menganalisis pengaruh antara ukuran partikel sedimen dan bahan organik terhadap kelimpahan kerang darah (A. granosa). Sampel sedimen dan kerang darah diambil menggunakan Eckman grab dari 4 stasiun, disetiap stasiun terdiri dari 5 titik sampling. Hasil penelitian menunjukkan bahwa kondisi lingkungan perairan Tanjung Balai Asahan masih mampu untuk mendukung kehidupan kerang darah. Jenis sedimen di perairan ini adalah didominasi oleh lumpur berpasir. Diameter rata rata sedimen (Mz) 3-7,7Ø dengan klasifikasi pasir sangat halus-lumpu sangat halus. Nilai rata-rata kandungan bahan organik sedimen tertinggi terdapat pada stasiun 2 (13,70%) yang terletak di sekitar hutan mangrove yang termasuk dalam klasifikasi bahan organik sedang. Nilai rata-rata kelimpahan kerang darah (A. granosa) tertinggi terdapat pada stasiun 4 (54 ind/m2), dengan pola sebaran mengelompok di semua stasiun. Hubungan karakteristik sedimen dengan kelimpahan kerang darah (A. granosa) di perairan Tanjung Balai Asahan tergolong hubungan yang kuat dengan nilai koefisien determinasi (R2) sebesar 0,529. Artinya ukuran partikel sedimen 52,9 % mempengaruhi kelimpahan kerang darah (A. granosa) diseluruh stasiun sementara 41,7% sisanya dipengaruhi oleh faktor lain yang tidak diteliti. Hubungan kandungan bahan organik  dengan kelimpahan kerang darah (A. granosa) tergolong hubungan lemah, dengan nilai koefisien determinasi (R2) sebesar 0,004. Artinya kandungan bahan organik sedimen 0,4% mempengaruhi kelimpahan kerang darah (A. granosa) diseluruh stasiun sementara 99,6% sisanya dipengaruhi oleh faktor lain yang tidak diteliti
