Abstract

This research was conducted in April 2019 to determined TSS concentrations using Landsat 8 OLI Satellite imagery and of to the coefficient TSS concentrations at period of before and after Lapindo mudflow event using Landsat 8 OLI satellite imagery in Porong River estuary Sidoarjo Regency East Java Province. TSS from 25 sampling points with 3 replication were taken from the estuary. The result showed that fluctuation of TSS occured around Porong River estuary before and after Lapindo mudflow event from 2000-2019. Algoritm of Budhiman (2004) got the best result for analyst TSS concentration around Porong River estuary. The highest concentration was in estuary. In 2008, the concentration in estuary was 216,07 mg/l. (R2 =0,915 ; r = 0,957). The Development of Algoritm of Budhiman (2004) produced formula of TSS (mg/l) = -6.7625 + (1.2129 * (8.1429 * (Exp (23.704 * 0.94 * Band-Red))))

Abstract

This research was conducted in May - August 2018 in the waters of Sasak Beach Pasaman Barat, West Sumatra Province. The purpose of this research was to determine the relative sedimentation velocity, the type of benthic foraminifera, and the distribution pattern of benthic foraminifera in the waters of Sasak Beach Pasaman Barat, West Sumatra. The method used in this research is purposive sampling method which is divided into 3 stations. The highest relative sedimentation velocity is found at Station I with a value of 28.0%, the relative sedimentation velocity is highest at station II with a value of 35.0%, and at station III 20.0%. The most commonly found foraminifera species are Ammonia beccarii, Quinqueloculina disparilis and Quinqueloculina laviegata. Benthic foraminifera from 3 observation stations can be divided into 6 groups. Group I was characterized by Ammonia beccarii (Line Form B), Ammonia beccarii (Line Form C), Textularia aglutinans and Trochammina inflate. Group II is characterized by Ammonia beccarii (Line Form A, B and C), Nonionoides gratelouupi, Quinqueloculina laviegata, and Spiroloculina laviegata. Group III is characterized by Ammonia beccarii (Line Form A, B and C), Spiroloculina laviegata, and Triloculina oblonga. Group IV is characterized by Ammonia beccarii (Line Form A, B and C), Nonionoides gratelouupi, Quinqueloculina disparilis, and Miliolina subrotunda. Group V is characterized by Ammonia beccarii (Line Form A, B and C), Quinqueloculina laevigata and Spiroloculina laevigata. Group VI is characterized by Ammonia beccarii (Line Form A, B and C), and Sigmoilinita distort. The distribution pattern of benthic foraminifera tends to clumped

Abstract

The research was conducted on January 2015, in the waters of the Sungai Bela Estuary,Indragiri Hilir Regency, Riau Province. The research purposed was to define the habitatcharacteristics, vertical distribution, and analysis of correlation between habitat parameters andabundance of windowpane oyster (Placuna placenta). There were 4 stations and each stationdivided into 3 sampling points based on the depth, they were <2 meter, 2–4 meter, and >4meters. Results shown that good habitat characteristics for windowpane oyster was ontemperature of 27.77 0C, Total Suspended Solid on 24.33 mg/L, current speed on 0.02 m/s, pHon 7.87, salinity on 20.60/00, DO on 7.63 mg/L, BOD on 4.17 mg/L, Nitrate on 0.07 mg/L,phosphate on 0.05 mg/L, and organic on 30.07%. The highest abundance of windowpane oysterwas on station 4 (11.000 Ind/Ha). While in vertical term, the highest abundance was at <2meter depth. The distribution pattern of windowpane oyster was evenly at station 1 andclumped in station 2, 3 and 4. Result of correlation abundance of windowpane oyster effect oncurrent speed was r= -0.711, pH was r= 0.649, the abundance of phytoplankton was r= 0.688,and mud substrate was r= 0.535.

Abstract

The study about habitat characteristics and population structure razor clam (Solen lamarckii, Chenu 1984) in intertidal zone Apiapi Village Bandar Laksamana District Bengkalis Regency conducted on January 2020. The purpose of this study was to analyze about habitat characteristics and population structure of razor clam and the correlation between substrate particle size and population density of razor clam. The habitat parameters measured include the physical and chemical parameters of sea waters. Determination of the station using purposive sampling method. Razor clam samples were collected by using a 1 x 1 m2 frame that laid along a transect. There were 4 plots and 3 subplots along the transect as replications. The result showed, the sediment tipe was sandy substrate, organic material was low, total suspended solid was high. Population density of razor clams was 3.3-23.3 Ind/m2. The distribution pattern of razor clams through each plot was uniform. While, the most common size of razor clam 5.04-5.62 cm. The correlation between particle size and population density of razor clam was strong.

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

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
