Abstract

Intensive monitoring is essential for shrimp health and productivity, but current water management in shrimp farming is time-consuming due to the need to monitor various parameters. Oxidation-reduction potential (ORP) is a potential water quality summary parameter for shrimp farming, as it's sensitive to water chemistry changes. This study assessed ORP as a summary parameter. Real-time ORP data was collected from a pond in Cipatujah, Tasikmalaya, from September to October 2022. The physical, chemical, and biological water quality data and treatment dosage data were collected to analyze the changes in ORP value over time. The standard deviation for ORP was below 1% for hourly averaging, below 12% for daily averaging, and below 23% for weekly averaging. However, no direct correlation was found between ORP and other water quality parameters. While ORP changed before and after some treatments, it couldn't reliably determine preferred water management conditions due to scattered information. Thus, the current approach of analyzing several parameters remains preferred, as ORP didn't show significant patterns. This suggests that more research is needed to explore alternative approaches for intense yet rapid water quality monitoring in shrimp farming.
