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

This research was conducted on 27 April-30 May 2019 at Tiram Beach, Karambia Ampek Beach and Gosong Beach, Padang Pariaman Regency, West Sumatra Province. This study aims to determine the relationship between sediment grain size and the number of turtle eggs. The method used in this research is purposive sampling. The sampling location is divided into 3 stations, each station is divided into 5 sampling points in order to obtain 15 sampling points, of which the fifteen sampling points are the usual nesting sites for turtles. Sediment samples were taken approximately 500 grams, put in a plastic bag, then labeled and then the sample was taken to the laboratory for analysis. The procedure for analyzing the sediment grains for sand and gravel fractions used the wet sieving method, for the sludge fraction was analyzed using the pipette method. The results from the wet sieving method and the pipette method were combined and the mean size (Mz) was obtained. Measurement data were analyzed using linear regression analysis, then correlation and regression analysis to determine the form of the relationship and the strength of the relationship between two or more variables. Sea turtles will lay eggs, namely the mean size ranges from 1.13-1.8 Ø. The coefficient of determination (R2) = 0.53 and the correlation coefficient r = 0.73. This means that the coefficient of determination shows the average diameter (mean size) affects 53% of the number of turtle eggs, while the other 47% is influenced by other factors, for example vegetation around the coast..

Sediment sampling was conducted at nine sampling points using purposive sampling technique.Analysis of the sediment fraction was carried out using the wet sieveand pipette methods. The results of the study the Ulakan Tapakis waters had 4 types of sediment namely: sand, muddy sand, sandy mud and mud,which is dominated by sandy mud. The sedimentary statistical parameters showed the value of mean diameter (mean size) range from 0,23-5,73ø with the clasification of coarse sand to medium silt. Skewness values range from -0,90-0,42ø with the clasification of  very negative skewed to very positive skewed. The values of sorting ranges from 2,04-2,53ø with the clasification of very poorly sorted. The value of kurtosis range from 0,47-9,31ø with the clasification of very platikurtik to leptokurtik extreme, indicate the waters under the influence of current conditions that tend to be unstable and the number of anthropogenic aktivities. Keyword: Sedimentary Characteristics, Sediment statistics, Ulakan Tapakis

Abstract

ABSTRACT This research was conducted in Lagoi Waters Banyan Tree Bintan Region to observe  effect accumulated sediment on coral. Three stations were selected forthe measurement of accumulated sediment was conducted using sediment traps which is apllied in the station of coral observation for 21 days. Point Intercept Transect (PIT) was used for the observation of coral reef. Regression analyses was applied clarify the correlation between accumulated sediment  and coral reef. The result of this study showed that the rate of accumulated sediment  in all observation stations ranged from 1.49 – 2.90 mg/cm2/day. The effect can be categorized as low to medium. The condition of coral reef in Lagoi Waters Banyan Tree Bintan Region is classified in good, indicated by  percentage of coral cover in observation stations ranged between 50-74%. The result of regression analysis showed that the accumulated has negative impact of life coral reef in Lagoi Waters Banyan Tree Bintan Region.Keywords : Accumulated sediment, Coral reef, Lagoi Waters.

Abstract

ABSTRACT Diatom is the most primary producer in marine waters and is abundant in surface areas that have sufficient light intensity and are rich in nutrients. This research was held on 12-24 May 2018 in the waters of Pangkalan Sesai village, Riau province. The study aims to analyze the concentration of nitrates, phosphate, silicate and analyze the abundance of planktonic diatoms as well as see the relationship of nitrate, phosphate and silicate against diatomic abundance of planktonic. The method used in this research is a survey method that is to perform observations and sampling directly, then proceed with the identification of planktonic diatoms samples in the laboratory. Water quality measurements are done in situ and ex situ consisting of parameters, physical biology, and chemistry. The concentration of nitrate ranged from 0.0367 – 0.0506 mg/l, phosphate concentrations ranged from 0.0840 – 0.1397 mg/l and silicate concentration of 0.0502 – 0.0692 mg/L. Diatom planktonic was found in the waters of Pangkalan Sesai village as many as 9 (nine) genera. Based on the results of multiple linear regression analyses obtained the value of the physical correlation (R) with the value 0.667 indicates that the relationship between nitric concentration, phosphate and silicate in diatoms is moderate. Then the value of R Square (R2) is worth 0.444 meaning the percentage of donations from the variable nitrate, phosphate and silicate against diatoms is 44.4% and the remaining 55.6% is influenced by other factors.Keyword: The abundance, nitrate, phosphate and silicate, Diatom, Pangkalan Sesai
