This study is an observational study with descriptive design. The study population was all the result of the disposal of liquid waste Arya DutaMakassar hotel. Samples are Inlet and Outlet of the Waste Water Treatment Plant (WWTP). Grab sampling technique that sampling where the sam-pling at a certain time is 08.02 hours in the morning and afternoon at 15:00.

On average pH Inlet as much as 7.25 and an average outlet pH levels as much as 5.08. On average Inlet BOD as much as 237.79 mg / L and for the aver-age Outlet BOD as much as 33.69 mg / L. On average Inlet COD concentration of 400 mg / L and for the average Outlet COD content of 160 mg / L. On average Inlet TSS levels as much as 0,026 mg / L and for the average Outlet TSS levels as much as 0,015 mg / L and the processing is done four times stages: Preliminary treatment, primary treatment, secondary treatment, and Tertiary treatment.
