| Summary: | In the year 2021, the Indonesian textile industry has grown for 12.45%. This growth will be affecting the number of txtile waste produced, which consists of organic dye, binding agent, and additives that are hard to degrade naturally. This calls for the development of a method to degrade organic waste that is practical and low-cost in practice.
Photocatalysis has become an interesting method for organic waste degradation due to its low cost and practicality. ZrO2 is one of the photocatalyst that has been studied thoroughly for its use as organic color degradation for its similar properties to TiO2 and has an advantage with its better thermal stability and better redox ability. To overcome its high band gap, usually some kind of noble metal is applied to ZrO2. Nickel has been shown to be able to lower the band gap of ZrO2 and heighten its photocatalytic activity.
From the experiment done concerning the photocatalytic degradation of methyl orange using ZrO2/Ni photocatalyst, it is found that the band gap for each variant of calcination temperature is 4.01 eV, 3.74 eV, and 2.98 eV for 400 oC, 500 oC, and 600 oC calcination temperature. It is also found that the highest rate of degradation was found in the 400 oC calcination temperature with dye pH at 10 with the rate constant 22,39 min-1.
