Shrimp L. vannamei Boone (1931)) has become a global market product and has become a major species for cultivation. This species, which has many advantages and is intensively cultivated to obtain maximum production. However, wastewater from intensive shrimp culture is known to have a negative impact if directly discharged into the environment, so a wastewater treatment plant (WWTP) is needed before being discharged into the environment. This study aims to investigate the water quality of intensive shrimp cultivation at the Millennial Shrimp Farming (MSF) which is equipped with a waste processor at the Brackish Water Cultivation Center (BPBAP), Situbondo, East Java Province, Indonesia from January to April 2023. Water quality data were collected randomly at 7 data collection times during shrimp maintenance from WWTP wastewater. Water quality is analyzed based on the official applicable method, namely the Indonesian National Standard (SNI) and is carried out at the BPBAP Situbondo Laboratory.The chemical characteristics of shrimp cultivation wastewater based on the intensive system in the millennium intensive farming (IMF) ponds after treantemt were obtained still in accordance of range of water quality parameter values during intensive shrimp cultivation systems to environment. However, physical aspects, namely Total Organic Matter (TOM), turbidity and BOD need serious attention. The density of vibrio bacteria, yellow vibrio colonies and green vibrio colonies in wastewater after treatment still allows for environment. Monitoring the quality of wastewater and wastewater treatment plants needs to be carried out routinely before discard to environment and for the success of shrimp cultivation, as well as maintaining and preserving water quality that is suitable for shrimp life during the maintenance stages.
