“…stated that the organic carbon and nitrogen has an impact on surrounding environment, this study is related to offshore aquaculture where the fish-feeding wastes will tremendously impact the water. Another previous research which was also diccussing about offshore aquaculture in Weh Island was published by Wisha et al (2019). Thus, a study assessing the suitability of offshore aquaculture, that will be impelemented, based on hydro-oceanography conditions in the Weh Island is essential.…”

The waters of Weh Island, Aceh Province has potency become the area for offshore aquaculture. Offshore Floating Net Cages can be an appropriate technology in increasing the biomass cultivation in Weh Island waters. However, no feasibility study has been done. Therefore, this study aims to examine the suitability of offshore aquaculture locations in the East and South regions of Weh Island Based on Hydro-oceanography parameters. The parameters examined were water quality parameters such as temperature, brightness, pH, salinity and dissolved oxygen. In addition, we also examined the aspects of physical oceanography such as tides, currents and bathymetry. The results show that the water depth ranged from 0-57 m. The tidal type in the Weh Island waters is mixed tide prevailing semidiurnal with the tidal range of 1.9 m. The average of current speed ranged from 19.03-37.67 cm/s with the directions predominantly toward northwest and southeast. It is concluded that the water quality data show that the eastern and southern parts of Weh Island are categorized as the feasible locations for offshore aquaculture.

“…Budidaya keramba jaring apung yang dibuat dengan material konstruksi ramah lingkungan serta mudah didapatkan di lingkungan sekitar merupakan implementasi dari pembuatan konstruksi konsep budidaya adaptif di wilayah pesisir. Kondisi hidrogeografis wilayah pesisir yang ideal adalah zona yang tepat untuk digunakan sebagai tempat implementasi budidaya keramba adaptif (Wisha et al, 2019).…”

Fish farming with adaptive cages is an alternative for developing fishery business activities in coastal areas. The purpose of this study was to analyze the potential for developing adaptive fish cages farming as a form of adaptation to the impact of tidal flooding and climate change. This research was conducted in Bandengan Village, Pekalongan City from July to August 2022. The research method used was descriptive qualitative with purposive sampling and then a SWOT analysis was carried out. The results showed that the water quality parameters at the aquaculture location were still feasible and suitable for fish farming activities. Then, for harvest productivity indicators, it was still quite appropriate and profitable for this operational business cycle. Furthermore, from the analysis of internal business factors identification, 6 elements of strength and 4 elements of weakness affected the operation of fish farming. Meanwhile, from the identification of external business factors, there were 5 elements of opportunity and 2 elements of threats that could affect the operational aquaculture cycle. From the results of SWOT matrix analysis, by comparing the elements of business opportunities, weaknesses, strengths, and threats, a comparison point was obtained between 2.04 and 1.38, or it was in first quadrant in SWOT matrix, meaning good strength to be developed further. In conclusion, fish farming activities with the concept of adaptive cages were very feasible and profitable to be developed in coastal areas that are vulnerable to tidal flooding and climate change effects.Key words: Coastal, Climate change, Development, Fish aquaculture, SWOT

“…Several previous related studies have been published that determine the oceanography profiles in Sabang Bay such as defined the influence of surface current on the distribution of surface temperature evoked by seafloor fumaroles, while Wisha et al (2019) and Ondara et al (2019) assessed the feasibility of offshore aquaculture based on the hydro-oceanography data. Nevertheless, the sedimentation issue is rarely studied in Sabang Bay.…”

Sabang Bay is one of areas of significance in Weh Island that becomes a center of marine tourism. Recently, massive urban development in coastal areas impacts on the increase of marine pollution and sedimentation issues within the bay. This study aimed to determine hydrodynamic characteristics and its influence on evoking sedimentation within the bay. Acoustic Doppler Current Profiler (ADCP) was installed within the bay for 30 days, which recorded surface elevation, waves, and sea currents. Sediment transport along the coast was determined by comparing the sediment transport and waves energy component in the form of flux equation. Tidal current speed ranging from 0-0.2 m/s moves predominantly southeastward and northwestward during flood and ebb tides, respectively. Significant wave height (Hs) ranges from 0.18-1 m with the period span of 3.5 seconds propagates toward within the bay, resulting in enhanced sedimentation within the bay caused by the wave-induced scour and turbulence. Sediment budget transported within the bay reaches 1586.18 m3/year. This proves that the sediment movement extremely occurs within the bay wherein the concentration of suspended sediment ranges from 5-35 mg/L and 2-25 mg/L during the high tidal and low tidal conditions, respectively. Scour and turbulence events are strongly induced by internal solitary waves generated from the Andaman Sea that results in increased coarse-sized sediment deposition when the flood tide takes place. While, during ebb tide, the widespread distribution of suspended sediment will occur over the bay.
