The utility of synthetic cleaners or commonly called as detergents have developed far indeed in this century. The effective and efficient use of detergents in cleaning process, was attracted to be used in laundry?s industry commercially, though, it has some drawback to the society and environments. Since the active materials in the compounds can cause irritating to the skins, cataracts to mature eyes and some other environmental issues due to the excess of foams can prevent oxygen dilution in the water so it be hazardous to water living organisms. Once the promising method to solve this problem is by photo-degradation using photo-catalyst. Photo-catalyst is the process using light and catalyst in order to accelerate chemical transformation, thus, solar or uv-rays can be used as light sources. This research aims at to show the ability of catalyst TiO2 to degrade active material in linear alkyl benzene sulphonate (LAS) and alkyl benzene sulphonate (ABS) which is available in commercial detergent. Photo-degradation of LAS and ABS compounds was determined by optimum capacity TiO2 and irradiance time. Whereas, for environmental application, the degrade compounds such Rinso® and Wipol® was chosen since it is commonly used in daily life. Beside, artificial water waste and laundry water was chosen to show the environmental effect. The result shows that the optimum number of catalyst TiO2 addition for LAS degradation was 1.5 g, and optimum time was 120 minute. Whereas the optimum number of catalyst TiO2 addition for ABS degradation was 2.0 g, and optimum time was 120 minute as well. Thus, for detergent Rinso®, at optimum catalyst addition, we found degradation number was 75.83%, and for detergent Wipol®, at optimum catalyst addition, we found degradation number was 57.94%. Whereas, for artificial waste at optimum catalyst addition, we found degradation number was 91.32%, and for laundry water waste at optimum catalyst addition, we found degradation number was 70.27%.Key words : Photodegradation, surfactant, TiO2, photocatalyst

Abstract â”€ Pollution that occurs in the community is caused by solid or liquid waste. One of the pollutants that are discharged into the environment are dyes. The dye waste originates from the coloring and dyeing process which is discharged directly in large quantities into the environment without prior processing. While the environment has certain limits to degrade the incoming compounds or dyes. One alternative method used to remove Rhodamin B dyes is the biosorption method. This method is believed to be able to eliminate pollutants in the waters because of its absorption which is quite effective at a relatively low cost, easy workmanship and the materials used are easily obtained such as kepok banana peels. This research uses the Batch method by looking at the effect of pH and concentration of the solution on the absorption of Rhodamin B by kepok bananas (Musa balbisiana Colla). The results showed that the optimum conditions occurred at pH 3 with 58% absorption of Rhodamin-B, concentration of 120 mg / L with 96% absorption of Rhodamin-B. The interaction between adsorbent and adsorbate is determined by the study of adsorption isotherms including the Langmuir isotherm and the Freundlich isotherm. In order to obtain Langmuir equilibrium with qmax of 25.9067 mg/g. Characterization of kepok banana peel using FTIR to see functional groups after activation.Keywords : Biosorption, Rhodamin-B, kepok banana peel (Musa balbisiana Colla), Batch methodÂ Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â

The textile industry sector in Indonesia is progressing. This progress is not followed by good and effective waste management. Methyl green dye waste is one example. Methyl green is organic waste that is difficult to decompose and is toxic. Therefore, an effective method is needed to decompose organic waste into environmentally friendly compounds using the photolysis method. This study aims to obtain the optimum time and the optimum concentration of TiO2 doping on the degradation of Methyl green by photolysis. The percentage of degradation of Methyl green was obtained from the measurement of the absorbance value using a UV-Vis spectrophotometer at the maximum wavelength of Methyl green (λmax) and the maximum wavelength was obtained at 640 nm. The results are the optimum time of degradation of Methyl green dye at radiation time of 150 minutes with a degradation percentage of 97.5%. In the variation of TiO2 dopant concentration, the optimum concentration of TiO2 dopant was found at 10% ZnO-TiO2 with 95% degradation.

Lead metal is one of the hazardous metals produced from industrial activities in Indonesia and can pollute the environment. The maximum level of Pb2+ ions in waters is 0.03 mg/L. If the Pb2+ ion level exceeds the predetermined level, it will have a harmful effect on the environment and living things. Adsorption is a method that can be used to reduce lead metal levels in water. The adsorbent that can be used is xerogel, which produced from durian peel (Durio zibethinus Murr.). The purpose of this study is to determine the optimum conditions of absorption and determine the absorption capacity of xerogel from durian peel against Pb metal. In this study, the batch method was used for the adsorption process by varying contact time and adsorbent contact mass. The results of this study obtained the absorption capacity under the optimum conditions of contact time of 60 minutes, and an adsorbent mass of 0.2 grams of 6.04 mg/g.

The photosonolysis method has been investigated to degrade the metanil yellow in a sample solution using the catalyst of TiO2. This study aims to determine how the effect of adding catalyst mass to the degradation of metanil yellow. The variation of the mass of the catalyst used to degrade the metanil yellow dye is from 0.5 grams, 0.1 grams, 0.15 grams, and 0.25 grams at 120 minutes according to the optimum time. The UV-Vis spectrophotometer was used to calculate the absorbance of metanil yellow before and after degradation processes, while FTIR was used to determine the spectrum and functional groups before and after degradation. The results of the measurement of the maximum wavelength of the color of metanil yellow using a UV-Vis spectrophotometer were 434 nm with an absorbance value of 0.267. In the variation of the catalyst mass, the optimum mass obtained at 0.1 grams of TiO₂ catalyst with %D obtained was 35,58 %. In this study, the presence of hydroxyl radicals produced during photosynthesis plays an important role in degrading metanil yellow.
