Hydro-oceanographic condition (Tide, Sea Current, and Waves) of Nongsa Batam Sea

Abstract

Tanjung Bemban is one of the seas found in the Nongsa sub-district, Batam city which is currently developed as a tourist attraction. This research aims to find out the hydro-oceanographic component, which consists of tide and the current and wave pattern in the sea of Tanjung Bemban Nongsa. To collect the data regarding tide, Tide Pole method, using measuring sign, is used, To collect data of sea current, Float Tracking (Lagrangian) method, by measuring distance and displacement of floating objects in the sea, is utilized, To collect the data of the wave, Wave Pole method, by measuring wave height, is employed. Based on the result of the research, it is clear that the tide of the sea is categorized as the semi diurnal, since there are two tides in one day with identical height, which occur sequentially and regularly. The highest flow reaches 260 cm and the lowest ebb 19 cm in the 4 days of observation, with 15 minutes interval. The measuring of ocean current is carried out for every 30-second intervals. Current velocity in Nongsa sea ranges from 0.02 m/s to 0.26 m/s. The current moves from east to southwest and west, even though some move northwest and north. Wave height is quite low, between 18 cm and 23 cm. Hydro-oceanographically, the Tanjung Bemban Nongsa area can be developed into a strategic tourism area

Hydrodynamic model approach to study the pattern of sea surface currents around the Tanjungpinang City reclamation site

“…This phenomenon can occur due to the geographical position and morphological landscape of the coast at the study site. Morphological profile of the beach (coastal) of the research location is a beach with many settlements and dense activities [18]. In the northern part, the beach profile is in the form of a narrow strait where at high tide water masses will accumulate to this location.…”

Perencanaan Jetty di Pantai Bahagia Batam sebagai Upaya Pencegahan Abrasi Pantai

“…Pada daerah Nongsa berdasarkan penelitian terdahulu, kecepatan arus paling tinggi yang didapat sekitar 0,5 m/s dan kecepatan arus paling rendah sekitar 0,001 m/s. Pada perairan tersebut, arah arus bergerak dari timur menuju barat daya beserta barat, dan ada juga bergerak menuju barat laut dan utara (Irawan et al, 2018). Kecepatan arus yang terjadi tergolong tinggi (>0.001 m/s) (Tanto et al, 2017)…”

Tingkat Kerentanan Pesisir Di Utara Dan Timur Pulau Bintan Provinsi Kepulauan Riau Tahun 2020

“…Pesisir utara dan timur Pulau Bintan dimanfaatkan sebagai kawasan permukiman, wilayah konservasi padang lamun serta pariwisata. Sektor pariwisata merupakan aktivitas paling dominan di pesisir utara dan timur Pulau Bintan hal ini dapat dilihat dari begitu banyaknya fasilitas pendukung kegiatan pariwisata seperti hotel dan resort yang dibangun di sepanjang pantai utara dan timur Pulau Bintan (Irawan et al 2018;Suhana et al 2016Suhana et al , 2018 dan masih terus berkembang. Penelitian mengenai kerentanan pesisir di pantai timur Pulau Bintan pernah dilakukan oleh Suhana et al (2016), dari hasil penelitian tersebut disimpulkan bahwa tingkat kerentanan pantai timur Pulau Bintan berada dalam kategori rendah.…”
