Organic Material Solubility and Dynamic Modelling Analysis of Intensive Shrimp Farming Activities in the Coastal Area of Pekalongan, Indonesia

The interaction between water and soil quality in intensive shrimp farming significantly influences the success of aquaculture operations. This study aims to examine the correlation between fluctuations in water and soil quality in intensive shrimp ponds and analyze the solubility level of organic matter using a dynamic system modelling approach. The research method used a causal ex post facto design, collecting data systematically from intensive shrimp ponds. The findings indicate that increased shrimp growth stimulates higher feeding activity, which subsequently raises waste production and organic matter solubility within the pond ecosystem. Over time, this process reaches a saturation point. By the fifteenth week of the operational cycle, the pond’s waste carrying capacity decreases, ultimately affecting shrimp farming productivity patterns. Throughout the farming cycle, fluctuations in water and soil quality parameters demonstrate this dynamic interaction. The study identifies a strong correlation between these factors, with patterns following an oscillatory trend in the model. The ecosystem’s carrying capacity primarily depends on waste load levels, oxygen availability for organic matter absorption, and the overall condition of the aquatic environment. Organic matter solubility exhibits an accumulative pattern throughout the operational cycle, highlighting its crucial role in ecosystem dynamics. The study concludes that water and soil quality are inherently linked to the stability of the pond ecosystem. Additionally, the presence and distribution of organic matter, as revealed through dynamic modeling, serve as critical factors influencing the ecological balance in shrimp farming systems.
