The impact of the increasing volume of waste in the Putri Cempo TPA causes the emergence of pollutants in the form of liquid, gas or solid. Gas is a dangerous pollutant because it can cause respiratory disease and even death. methane gas (CH4), sulfurdioxide (SO2), ammonia (NH3), and hydrogen sulfide (H2S), so that it can be the cause of respiratory (respiratory)-related diseases cardiovascular, and physiological changes such as pulmonary function and blood pressure. This study tries to identify pollutant gases that arise in the Putri Cempo TPA and the detection method uses ZnO-TiO2-GO Material which previously used an adsorbent solution. The use of this material has the advantages of being practical, safer and easier to recycle. The gas identification carried out includes SO2, O3, NO2, H2S and NH3 gases. ZnO-TiO2 and GO materials were varied into variation A, B, C ,D And E. The results showed that The results show that the composition of TiO2; ZnO Graphene C (45%; 45%, 10%) shows better results for detecting NO2 gas than the p-aminodimethylaniline working solution used for laboratory measurements. The results show that the composition of TiO2; ZnO Graphene E (60%; 30%, 10%) shows the composition's ability to detect 10 times more H2S gas than the p-aminodimethylaniline working solution but the ability to detect NH3 is lower than the p-aminodimethylaniline working solution. composition variations in TiO2; ZnO ; Graphene B (30%; 60%, 10%), and D (80%; 15%, 5%) can detect exposure to SO2 and O3 gases 6 times more than p-aminodimethylaniline solution. From various compositions, it shows that TiO2, ZnO, Graphene materials are more dominant than aminodimethylaniline solution except for the detection of NH3 pollutant.  The results of the research recommendations need to be developed prototypes for the detection of the five pollutant gases without having to go through laboratory testing. The development of a prototype of the pollutant gas detection tool can speed up the measurement of gas pollutants. So that it is easier for analysts to measure gas pollutants. It is necessary to develop the effect of the concentration of adsorbed pollutant gas on the composition of materials with various conductivity of material compositions for further research.
