Abstract

The effect of tidal fluctuations on rising sea levels has altered the ecological dynamics of coastal waters. Therefore, this study aimed to evaluate water and soil quality in shrimp farming ponds due to the effect of tidal fluctuation. A causal ex-post facto design concept was used with observed indicator variables, including water quality, soil quality, and tidal wave fluctuation data. The results showed that TOM 152.64-169.56 mg/L and NO₂ 1.064 mg/L exceeded the threshold values for water quality parameters. Soil pH values, redox potential, organic carbon, organic matter, and CEC ranged from 7.7 to 7.9, 11.79 to 16.80 mev, 0.36 to 0.45 mg/L, 0.45 to 0.50 mg/L, and 27 to 30 mg/L, respectively. Meanwhile, WQI and SQI of ponds ranged from 0.11 to 0.60 and 0.09 to 0.54, within the poor (0.33) and interval III (0.31) categories, respectively. The average tidal wave height in Probolinggo Waters over one year ranged from 0.84 to 2.90m. Additionally, the relationship between WQI, SQI, and tidal waves was described by the model Y = 1.000 + 2.480x. Several parameters had significant effect on the relationship, including TOM, Mg, hardness, CO₃, HCO₃, alkalinity, NH₄, NO₂, OM, and CEC. The increase in sea level is linked to changes in the biophysical environment and is associated with the impact of climate change on sea level rise. This study concluded that water and soil quality conditions in shrimp pond ecosystems in the coastal area of Probolinggo deteriorated in terms of suitability due to the intense and dynamic effects of rising tidal waves.
