description: Telah dilakukan penelitian untuk mengatenuasi jenis noise multiple pada data  seismik marine pada lintasan KM86-139 dengan menggunakan software “Vista”.  Penelitian ini digunakan untuk menerapkan metode surface related multiple  elimination (SRME) dan radon transform untuk mereduksi keberadaan multiple di  dalam data seismik dan menyisakan gelombang primer nya saja. Sebelum  menerapkan metode surface related multiple elimination (SRME) dan radon  transform dilakukan tahap pre-conditioning seperti direct arrival removal, dan  linear noise attenuation. Metode SRME pada metode penelitian ini dapat  menekan multiple pada offset dekat karena SRME tidak bergantung move out,  namun SRME dilakukan dengan cara memodelkan noise multiple dan dilakukan  pemisahan sehingga yang didapatkan hanya data primer nya saja. Metode radon  transform efektif dalam menghilangkan multiple yang berada di offset jauh karena  dengan offset yang cukup maka perbedaan move out antara refleksi primer dengan  multiple akan lebih jelas terlihat. Hasil penelitian dalam pengolahan data seismik  menggunakan SRME dan Radon Transform telah menghilangkan surface multiple  yang berada pada data seismik yang mana mengikuti velocity water bottom nya  yang berada pada kisaran 1480 m/s yang di dapat dari hasil velocity analysis.  Proses Radon Transform nya dilakukan pada gather yang telah terkena efek  Normal Move Out (NMO) dengan cut off hiperbolik -900 dan cut off parabolik  150 pada maximum offset 2000. Proses Surface Related Multiple Elimination  (SRME) dan Radon Transform telah menghilangkan surface multiple yang berada  pada data seismik. Namun masih tersisa jenis multiple seperti internal multiple.  Kata Kunci: Gelombang primer, multiple, direct arrival, surface related multiple  elimination, radon transform.    MULTIPLE ATTENUATION USING COMBINATION OF  SURFACE RELATED MULTIPLE ELIMINATION (SRME) AND  RADON TRANSFORM METHOD    Has conducted research for the attenuation types of multiple noise on marine seismic  data on the track KM86-139 using software “Vista”. This research is used to implement  a method of surface related multiple elimination (SRME) and radon transform to reduce  the presence of multiple in seismic and only leaving the primary wave. Before applying  the method of surface related multiple elimination (SRME) and radon transform,  conducted pre-conditioning phase as direct removal arrival, and linear noise  attenuation. SRME method in this research method can suppress multiple on near offset  because SRME does not rely on move out, but SRME is done by modeling a multiple  noise and separation so that it is only obtained the primary data. Radon transform  method is effective in eliminating the multiple in far offset because by having a  sufficient offset then the difference move out between a primary with multiple  reflections will be more clearly seen. The results of research in seismic data processing  using SRME and Radon Transform has eliminated surface multiple on seismic data  which follows velocity of its water bottom in the range of 1480 m/s and it can be  obtained from velocity analysis. Radon Transform process is done in the gather that  has been affected by the effects of Normal Move Out (NMO) with hyperbolic cutoff is  -900 and parabolic cutoff is 150 at the maximum offset 2000. Surface Related Multiple  Elimination (SRME) and Radon Transform process has eliminated the surface multiple  on seismic data, but still leave another type of multiple like internal multiple.  Key Word: Primary wave, multiple, direct arrival, surface related multiple  elimination, radon transform.
