Abstract
Modifikasi zeolit mangan dengan TiO2 sebagai filter gas buang kendaraan bermotor telah berhasil dibuat dengan mencampurkan zeolit mangan dan TiO2 serta Poly Vinyl Alcohol (PVA) sebagai perekat. Pembuatan filter dilakukan dengan metode reaksi padat-padat (solid State Reaction) kemudian dikarakterisasi struktur dan kristalinitas kristal menggunakan X-Ray Diffraction (XRD) dan morfologi serta komposisi kimia menggunakan Electron Microscopy - Energy Dispersive Spectroscopy (SEM-EDS). Hasil karakterisasi XRD dan SEM-EDS menunjukan bahwa penambahan TiO2 tidak mempengaruhi struktur kristal dari zeolit mangan yang dapat dilihat dari tidak adanya perubahan dspacing yang spesifik dan tidak terjadi pergeseran sudut 2?, namun terjadi penurunan intensitas puncak difraksi yang menandakan adanya penurunan persen massa salah satu komponen zeolit mangan yakni SiO2.

ABSTRACT
Modification of manganese zeolite with TiO2 as a motor vehicle exhaust gas filter has been successfully made by mixing manganese zeolite and TiO2 and Poly Vinyl Alcohol (PVA) as an adhesive. Filtering was carried out by the solid state reaction method, the crystal structure and crystallinity were carried out by using X-Ray Diffraction (XRD) as well as the morphology and chemical composition determination were done by using Electron Microscopy - Energy Dispersive Spectroscopy (SEM-EDS). The results of XRD and SEM-EDS meaurements showed that the addition of TiO2 did not affect the crystal structure of the manganese zeolite which could be seen from the absence of specific dspacing changes and no 2? angular shift, but there was a decrease in diffraction peak intensity which indicated a decrease in mass percentages of one component manganese zeolite namely SiO2. Furthermore, a test for filter performance in decreasing CO and HC gas contents was done using a Gas Analyzer and Atomic Absorption Spectrophotometer for Pb measurement. The results showed that the filter modification of manganese zeolite with TiO2 could reduce the contents of CO, HC and Pb, in which the filter without the addition of TiO2 and with the addition of 10 and 20% TiO2 decreased CO content by 48.29; 58,14; 58.00%; HC contents by 27.83; 37.97; 45.81%; and Pb content by 90.74; 92.08; 93.48% respectively.
