THE INFLUENCE  OF  VARITIAN TIME  WATER QUALITY OF INTEGRATED MULTI TROPIC SHRIMP CULTURE SYSTEM IN WEST SULAWESI

This study aims to determine the time variation of water quality in shrimp culture ponds with integrated technology multitrophic Aquakulture (IMTA) is vaname shrimp, tilapia, kekeranga and seaweed. The research was conducted in West Sulawesi by using two ponds A. measuring 3,675 m2 and 5,250 m2 with treatment B. (A) vaname intensive shrimp, red tilapia, oyster and seaweed (B) faname semi-intensive shrimp, red tilapia, oyster and seaweed. Monitoring of water quality was monitored every 3 hours for 24 hours including the quality of physics observed in situ,

. This research aims to study the time variation of water quality in shrimp culture ponds vaname with integrated technology multitrophic Aquakulture (IMTA).  Material and Methos: The study was conducted in the village pond Sinyonyoi, Districtnamely oxygen, temperature, salinity and pH. Research results obtained average is oxygen (4.6 mg / L), temperature (32.76 ^° C), salinity (23.7 ppt) and pH (8.7) and chemical quality in the form of ammonia, nitrite, phosphate, nitrate, organic matter and alkalinity in the analysis in the laboratory.

Kaluku, Mamuju, West Sulawesi province using 2 A. ponds measuring 3,675 m2 and 5,250 m2 with treatment B. (A) vaname intensive shrimp, red tilapia, oyster and seaweed and ( B) vaname semi-intensive shrimp, red tilapia, oyster and seaweed. Stocking density vaname shrimp, tilapia and seaweed in each treatment is shown in Table 1, as follows:

Results and Discussion some physical parameters were observed in situ in the form of dissolved oxygen, pH, temperature and salinity can be seen in the following figure: Table 1. The range of parameter values kuaitas water in shrimp culture ponds with multitrophic technology integrated aquaculture (IMTA) during the study.

Description: Pond A (intensive), Pond B (semi-intensive)

By using advanced electronic IMTA into the pond prawn, tilapia, seaweed and oyster can improve water quality and environment-friendly, seaweed as a supplier of oxygen, through photosynthesis during the day, indigo eaters plakton and oyster can absorb excess nutisi and contamination toksit that toxic, From the observation of water quality for the maintenance of 3-5 ppm dissolved oxygen content, temperature 29-31oC, 15-20 ppt salinity, water transparency of 25-70 cm and a pH of 7.8 to 8.2. Water quality parameters during maintenance Table 1.The research pond A (intensive) and B

(semi-intensive) in IMTA vaname shrimp is still within the limits eligible for shrimp farming.
