Abstract

Penelitian ini dilaksanakan pada bulan juli 2013 bertempat di Kelurahan Basilam Baru Kecamatan Sungai Sembilan Kota Dumai Provinsi Riau. Ekosistem mangrove mempunyai fungsi yang unik dalam lingkungan hidup. oleh karena adanya pengaruh laut dan daratan, mangrove mampu berperan sebagai penahan ombak serta penahan intrusi dan abrasi air laut. serta dapat dikembangkan sebagai wnawisata untuk kepentingan pendidikan dan penelitian. Penelitian bertujuan untuk mengkaji potensi ekosistem hutan mangrove di Kelurahan Basilam Baru untuk di kembangkan menjadi tujuan ekowisata mangrove, mengetahui tingkat partisipasi dan persepsi masyarakat, pemerintah, dan stakeholder lainnya dalam membangun ekowisata di Kelurahan Basilam Baru. Metode yang digunakan dalam penelitian ini adalah metode survei, yaitu dengan cara turun secara langung kelapangan untuk mengumpulkan data-data yang diperlukan. Wawancara terstruktur (kuesioner) dan non terstruktur (wawancara bebas mendalam) juga dilakukan untuk mengetahui respon-respon masyarakat sekitar dalam pengembangn ekowisata mangrove di Kelurahan Basilam Baru. Hasil penelitian menujukkan bahwa hutan mangrove di Kelurahan Basilam Baru memiliki kerapatan yang baik dengan kategori sangat padat. Hal ini ditunjukkan dengan nilai kerapatan pohon yang diteliti adalah 3955.56 Ind/Ha dan 7800 Ind/Ha, Ketebalan mangrove termasuk kategori tebal dan ekosistem mangrove di Kelurahan Basilam Baru memiliki nilai IKW sangat sesuai (S1) berdasarkan parameter pengembangan ekosistem mangrove.Keywords: Mangove, Ekowisata, Kelurahan Basilam Baru

Abstract

ABSTRACT This research was carried out in March 2019 on Toran Island, TWP Pieh Island and the Sea in the Surrounding West Sumatra Province. The purpose of this study was to determine the potential of marine ecotourism on Toran Island and its development strategy. The method used in this study is a survey method and the determination of sampling points using purposive sampling method. Data collected includes respondents' opinions, identification of ecotourism activities and measurement of water quality. The results of this study indicate that Toran Island has the appropriate potential to be developed as a marine ecotourism area. The results of the calculation of the land suitability index value for the recreational tourism beach category are at an average value of 85.2%. This value indicates that Toran Island is very suitable to be used as a marine ecotourism destination. The results of the SWOT analysis show several alternative management strategies that are appropriate for the development of marine ecotourism on Toran Island, namely: 1). Developing tourist objects and attractions by increasing facilities and infrastructure as well as tourist attractions with the quality and quantity of tourist objects that are more attractive and provide a distinctive charm for tourists. In this case the Toran Island attraction presents a tourist attraction in the form of the natural charm of the beach with white sand. 2). Developing a partnership between the local community and the government in terms of developing tourism facilities and businesses at the Toran Island tourist site. 3). Expanding promotion and marketing of Toran Island tourism objects from various local, regional, national and international market segments with a variety of promotional facilities and optimal tourism services.  Keyword: Potential, Marine Ecotourism, SWOT Analysis, Toran Island

Abstract

Heterotrophic bacteria have a role as decomposer of organic compounds (mineralization) and inorganic nitrogen (ammonia, nitrite, and nitrate) derived from industrial waste, decomposition of uneaten feed, faecal, excretion of fish and have the ability to inhibit the growth of pathogenic bacteria. This research was conducted in November untill December 2016. The results of antagonism test showed isolated bacteria have the ability to inhibit the growth of pathogenic bacteria (Vibrio algynolyticus, Aeromonas hydrophila and Pseudomonas sp.) Zone of inhibition in D5, D6 and D4 isolates classified in the strong category with zone of inhibition average of 10.5 to 11.8 mm and zone of inhibition in D1, D2, D3, D5, D7 isolates classified in the medium category with zone of inhibition average of 5.3 to 8.5 mm and each of the isolates are also classified in the weak category. The results of DNA analysis of heterotrophic bacteria isolated from marine waters of industrial area and low salinity of estuarine waters by using the PCR method technique 16S sequences found three strains of bacteria from the highest level of homology Bacillus toyonensis, Bacillus cereus and Bacillus pseudomycoides. D1 isolates has similarity to Bacillus cereus strain ASK16, D2 isolates to Bacillus toyonensis strain AC OPR1150Xg, D3 isolates to Bacillus pseudomycoides strain F1-8, D4 isolates to Bacillus cereus strain SBFW51, D5 isolates to Bacillus cereus strain OPP5 3-2, D6 to Bacillus cereus strain SBFW5S, D7 isolates to Bacillus cereus strain B4. Most of isolated bacteria obtained from the waters of industrial area because it receives much of nutrients that are very influential in the growth of bacteria.Kata Kunci : Bakteri Hetrotrofik, Antagonisme, Sekuens 16S rRNA

Abstract

This research was conducted in July 2016 at the coastal waters of Pasir Jambak Padang City West Sumatera Province with intention to determine the characteristics of wave and tidal currents. The stasion observation way is determined by using a purposive method. Research location divided into three stations, where each station consists of three sampling points, the distance between stations of approximately 100 m. Performed during 15 days of observation. Every station was placed parallel to the coastline, a distance less than 100 meters from the beach toward the Sea. High wave at high tide ranges from 0.21 - 0.33 m and 0.23 - 0.35 m at low tide. Wave period ranges from 1.54 to 2.23 seconds at high tide and 1.43 to 1.97 seconds at low tide. Wavelength ranges between 3.86 to 7.8 m at high tide and 3.35 to 6.08 m at low tide. Current velocity ranges between 0.37 to 0.64 m/sec at high tide and 0.36 to 0.51 m/sec at low tide.

AbstractThis study was conducted in the intertidal zone of Surantih Beach, South Coast Regency, in the West Sumatra province. It aims to learn the distribution pattern and abundance of bivalves (D. cunneatus and D. deloides). Sampling locations were chosen purposively with different characteristic. The field samples were collected with shovel along the transect line then filtered with 1 sq. mm in size for further analysis in the lab. The result showed that these two species are found, namely, D. cunneattus and D. deltiodes. The abundance of these bivalves in the intertidal of Surantih Beach ranges from 2.83 -3.63 individual per sq. meter where the highest one was found in the third station. These species have aggregated distribution structures in the area under study.Keywords: Bivalvia, Intertidal Zone, D. Cunneatus, D. Deltoides, Abundance, Distribution Patterns, Surantih Beach.
