Abstract

Sorake Beach is located in South Nias Regency and facing directly to the Indian Ocean which possessed a wealth of natural and diverse appeal had potential for ecotourism development. This study aims to determine the condition and potential of natural resources that can be developed, to analyze and formulate the concept of ecotourism development strategy in Sorake.Suitability tourism index in Sorake was at suitable level (S2 suitability). The results showed the calculation results of the IFE (internal factors) and EFE (external factor) had a value of 2.92 and 2.91 respectively. The internal factors was stronger than external factors. The priority strategy of future development suggested making programs and environmental activities that environmentaly friendly and making tourist zoning plan.Keywords: Strategy Development, Ecotourism, Tourism Suitability Index, IFE and EFE.

Abstract

ABSTRACTThis study was conducted in September 2014 in the coastal of Darul Aman Village Rupat District Bengkalis Regency. The Mudskipper (Periopthalmus variabilis Eggert) is one kind of fish are known to occupy beaches lined by mangroves. Mudskipper Fish has a bright prospect in the marine biotechnology industry such as food and pharmaceuticals. This study determined the density and reproductive aspects that include sex ratio, the level of gonad maturity, fecundity and diameter eggs located in the coastal of Darul Aman Village Rupat. The method used in this study is a survey method and made three square plots measuring 30 x 20 m2, for analysis in the laboratory using surgical methods, issued gonads and observe the gonads. The result show that the density of Mudskipper fish was low, the sex ratio was 2: 1 between male and female. All levels of gonadal maturity for female fish mostly at levels III, IV and V, whereas for male fish can be found at all levels (I-V). Fecundity values obtained ranged between 112.496-137.698 eggs and egg diameter sizes ranging from 0.235 - 0.55 μm.Keywords: Periopthalmus variabilis Eggert, Density Reproduction, Rupat

Hasil analisis kekeruhan berkisarantara 173–749 NTU, kelimpahan fitoplankton rata-rata yaitu <302 ind/l dan spesiesfitoplankton yang ditemukan paling banyak dari kelas Bacillariophyceae yaitu 16spesies. Konsentrasi nitrat berkisar 0,0625 – 0,9431 mg/l, sementara konsetrasi fosfatberkisar dari 0,2131 – 0,3466 mg/l. Pengukuran kualitas perairan seperti kecepatanarus 0,85 m/dtk, kecerahan 16,6 cm, kedalaman 3,77 m, suhu 29,7 ºC, pH dengan 7-8,DO 5,4 mg/l dan salinitas 20 ppt. Berdasarkan hasil penelitian, tingkat kekeruhan sudahmelebihi baku mutu lingkungan air laut, sedangkan tingkat kesuburan perairantergolong rendah. Nilai produktivitas primer kotor menunjukkan bahwa lokasi penelitianini, fotosintesis masih dapat berlangsung dengna baik, namun respirasi yang dibutuhkanlebih besar daripada proses fotosintesis.

Abstract

The research was conducted in February 2017 at Sakera coast Bintan regency of Kepulauan Riau Province,with the aims to determine the concentration of Nitrate and Phosphate in water, abundance of planktonic diatom and, the relationship between the concentration of Nitrate and Phosphate with abundance of planktonic diatom.The research methods used a was survey method. Each station consists of three sampling points. The results showed that the concentration of Nitrate ranged from 0.179-0.240 mg / L, whereas Phosphate concentration ranged from 0.175-0.194 mg/ L. The planktonic diatom found in the waters of Sakera coast consists of 2 ordo and 9 genus . The most dominant species were Isthmia sp, Chaetoceros sp and Nitzschia sp.The highest abundance was at station 4 which was a residential area (5540 ind /L), while the lowest was at station 1 which was the oil refining area (3488 ind / L). The relationship between concentration of Nitrate with diatom abundances has weak positive correlation, while the relationship between concentration of Phosphate with diatom abundances has weak negative correlation.Keywords : Coast Sakera, abundance, nitrate and phosphate, and diatoms

Abstract

This study was conducted in February 2016 in the strait between Belakang Padang Island and Sambu Island of Batam City in Riau Island Archipelago Province. The aim of the student has to understand the environmental deposition of Pulau Belakang Padang waters based on the analysis of surface sediments distribution. Surface sediment samples were taken using Eckman grab from 20 sampling points, to analyze the grain size and sediment composition. In general, the sediment characteristics of the study area is dominated by the fraction from fine to very fine sand. Environmenal deposition can be devided 4 groups. The first group has a weak current and very unstable oceanographic condition, the second group has a mean size that is more rugged and has lower percentage of clay fraction, third group was characterized by stronger current and slightly more stable oceanographic condition and fourth group has oceanographic conditions with the most strong and more stable current system.Keyword: Sediment, Distribution, Belakang Padang, Sambu, Batam

Abstract

The research was conducted from December 2014 to February 2015, in the coastal waters of Dumai, Riau Province. The research aimed to determine the tidal dynamics in relation to climate change. The research used survey method by performing 4 times periodically sampling. The result of measurement was then compared to Hydro-oceanographic Service Data.The results showed that tidal pattern in coastal waters of Dumai during a period of 3 months was classified into Mixed Semi-Diurnal Tides which occured 2 low tides and 2 high tides for 24 hours. Observations I-IV showed the tidal patterns were different because of different patterns of surface currents. Data of tidal pattern were compared to data obtained from Hydro-oceanographic data 3 years earlier showed a difference. Judging from the results of research that has been made known that there has been a rise in sea level if compared to data obtained from Hydro-oceanographic data 3 and 1 year before, namely an increase ranging between 19.5 to 22 cm. While the comparison of the data with the previous 2 years decreased, with a value of 45.5 cm. This means sea level in the study area has increased for 3 and 1 year. It was predicted that the existence of climate change has the effect of tidal conditions in these waters.Keyword : tidal pattern, climate change, Pangkalan Sesai, Dumai

Abstract

Abstract The rapid growth of industrial sectors in various countries leads to an increase in greenhouse gas emissions such as carbon dioxide (CO2) in the atmosphere. One important aspect of reducing carbon gas is the maintenance of forests and oceans to store carbon. One of the potential marine resources for storing CO2 is the seagrass. Waters of the North Sea Penyengat Island has a community of seagrasses composed by various types, one of which is Enhalus acoroides which has an important role as carbon store. This research was conducted in October-November 2017 in the waters of East Sea of Penyengat Island which aims to find out the condition of density and biomass on sea grass in Above ground and Below ground (rhizoma and root) density to seagrass biomass on seagrass. Data were obtained by using the quadratic transect method performed on 4 stations. The results showed that the density of seagrass in the study location was moderate, where the density of seagrass Station III was higher than other stations. The greatest biomass value is found in the rhizomes and roots of seagrasses in all four stations. Less seagrass areas are anthropogenic, ie station III which has a greater biomass potential than the seagrass area with the opposite condition. Keywords: Global warming, Biomass, Seagrass, Penyengat island.
