Industry of sarung samarinda products original handicraft from Samarinda province. Except it, liquid wastes also given production from color processing. The wastes have a bad potency because of colour contain. In order to, it was needing process before as a garbage to environment. The main research has decrease colour compound of direct black 38 in liquid waste from fabrication. It was done after electrocoagulation process. The variable studied were voltage between 6-12 volt, space of electrode between 3-7 cm, time of process between 3-7 cm, time of process between 45-225 minutes in the batch reactor with capacity one litres. it made for get the best condition. The experiment result show wave length of 505 nm with spectrofotometry device. Based on product, the best of voltage electricity of 9 volt, time of process 180 minutes, and space of electrode 3 cm. In order to, the best result can decrease color concentration of 94,29%. That method could be one of alternative decrease of waste Sarung Samarinda Industry
