One of the effects of Samarinda Sarong Industries is negative liquid waste from dying and coloring process. Therefore liquid waste must be treated before throwed away to water body. This research was done to treat liquid waste by activated carbon production from dirty coal as a adsorber. Adsorbtion was done by adding activated carbon to liquid waste during time contact 10 minuts, 20 minuts and 30 minuts. Filtrat was obtained measure by using UV-Vis spectrophotometer at the wave length of 355 nm . The result of the experiment showed that dosage of activated carbon optimum in 0,5% and time contact 30 minuts can reduce 98,42% colour content of the liquid waste.
