Abstract: Considerable visits from patients increases the content of ammonia within the liquid waste of the hospital which, in turn, results in water pollution. Adsorption of active carbon is an alternative technology in reducing the ammonia level of liquid waste. This research aims at revealing the contact time of active carbon plastic ore towards the degression of ammonia level of liquid waste. This research was an experiment designed by Pretest-Postest design with control. The population of the research was all the liquid waste taken from the influent of RSUD Al Ihsan Bandung, while the sample of the research was taken from the population by time combining collection technique. The collected data was then analysed using ANOVA. The results of the research show that the average of the degression percentage for contact time of sixty minutes is 1,840%, 90 minutes 35.07% and 120 minutes 48.77%. The value of t acquired from ANOVA testing is 0.001, smaller than 0.05 (α 5%). There is significant influence of the variations of contact time of active carbon plastic ore on the degression of ammonia level of liquid waste. The results of the research could be utilised by the hospital to manage its liquid waste.
