This research aims to study the activity of photoanoda TiO 2 / NiO on waste photoelectrocatalitic degradation of dyes and the number of microorganisms biodeinking. Preparation photoanoda Ti / TiO 2 -NiO done with the technique of wet impregnation, then composite TiO 2 -NiO sprayed on the surface of the electrode Titanium. Photoanoda characterization is done by X-Ray Diffraction (XRD), fourrier Transform Infra Red (FTIR) and TEM-SEM .. XRD diffractogram TiO 2 -NiO composite showed characteristic peak of TiO 2 -NiO at 2θ = 33 o . NiO existence characterized by FTIR absorption Ni-O at 412.77 cm-1. Meanwhile, TEM and SEM analysis showed TiO 2 with crystal size in the region of 50 nm on the surface of Ti plate. Fotoelektokatalitik degradation dye waste results biodeinking done using photoanoda Ti / TiO 2 -NiO and Ti cathode using a halogen lamp 300 W / m 2 . Results of the maximum degradation of dye wastewater biodeinking results shown in the voltage 6 volts with a flow rate of 3 mL / sec with% 90.10% decolorination reached. While the number of bacteria content analysis was performed using the method PJB (Calculation of Total Bacteria) with optimum results on the bacterial degradation of voltage 6 volts.

Secondary fiber has become a very important raw material for pulp and paper industry. In addition because the price is cheaper, can also help to preserve forests, reduce environmental pollution and reduce the use of water and energy. One source of paper that can be used as a source of secondary fiber is used newspapers. This is because newsprint is one type of paper that is widely used as the print media are published daily in large quantities and after being read normally be disposed. This old newspapers must undergo removal of various contaminants before undergoing the process of papermaking, one of the contaminants are difficult to remove the ink. Deinking process is usually through conventional deinking process. The deinking process is a process that produces solid waste that is classified as B3 waste from specific sources (Government Regulation No18 / 1999 and 85/1999 on Management of Hazardous and Toxic). In general, the solid waste containing toxic heavy metals derived from the water-soluble ink waste [6]. However, with developments in the field of biotechnology, conventional deinking process used for the processing of old newspapers began to turn with biodeinking process uses an enzyme to remove contaminants ink from old newspapers [9].
