Abstract

Dompu General Hospital as one of the health facilities in Dompu Regency must be able to treat

wastewater properly. The hospital' s Wastewater Treatment Plant (WWTP) needs to be evaluated periodically to ensure that its performance is effective and efficient in processing wastewater. This research used is an experiment by conducting observational with a descriptive approach to evaluate the performance of the wastewater treatment plant system and to determine the effectiveness of the Biofilter Anaerobic Aerobic WWTP at Dompu General Hospital. The results of the quality test wastewater sample Biofilter Anaerobic Aerobic WWTP obtained from the parameters of TSS, BOD, COD, Oil and Water parameters and pH, show show figures within the standard for hospital wastewater quality. The results of laboratory tests for the 5 parameters are as follows: Total Suspended Solids (TSS) with a standard of 30 mg/L obtained a waste treatment result is 18.0 mg/L. Biological Oxygen Demand (BOD) test obtained a waste treatment process was 1.47 mg/L. The waste treatment results of Chemical Oxygen Demand (COD) was carried out, 28.9 mg/L. The waste treatment result of Oil & Water was carried out<1,00 mg/L

A study by Putri et al. (2020) found that WWTP efficiency is highly dependent on hydraulic residence time and the type of biological reactor used.

According to Saputra & Widodo (2019), routine maintenance and monitoring of effluent quality are critical factors in maintaining the effectiveness of hospital WWTPs.

Based on the results of a study by Nuraini et al. (2022), hospital management awareness of environmental regulations has increased along with the enforcement of environmental laws.

Handayani et al. (2021) emphasize the importance of periodically evaluating WWTP performance to minimize the impact of water pollution around hospitals.
