In this research the S speed structure is investigated by seismogram analysis of Washington's earthquake, C022801L using data of TUC station, Tucson, Arizona, U.S.A. The seismogram comparison between the observed and the synthetic seismogram is conducted in time domain and three components simultaneously. The initially input for the calculation of synthetic seismogram is earth model of PREMAN and CMT solution from the earthquake. A low-pass Butterworth filter with corner frequency of 20 mHz is convolved to observed and synthetic seismogram. Waveform comparison shows a real deviation when travel time and waveform of some wave phase are compared, namely on S wave, surface wave of Love and Rayleigh and wave ScS and ScS-2. This research shows, how sensitive the waveform is to the earth model, better than the method of travel time or the dispersion analysis. Research hereinafter is addressed to finish the found discrepancies at S wave, surface wave of Love and Rayleigh and ScS and ScS-2 wave, in observation station TUC. To obtain the seismogram fitting, correction for S speed structure in earth model is needed, that are changes of earth crust thickness, the speed model of  in upper mantle covering the speed gradient of h and value of zeroeth order coefficient for the h and v, for accomplishing the discrepancies at surface wave of Love and Rayleigh. Further correction on S speed is conducted to accomplish the deviation at S wave at earth layering systems from Upper Mantle up to a 630 km depth. Mean while for the ScS and ScS-2 wave phase the correction is carried out on S speed in the earth layers up to CMB. Fitting Seismogram is obtained at waveform of various wave phases that is S wave, surface wave of Love and Rayleigh and ScS, ScS-2 wave, either on travel time or especially also at oscillation number in Love wave. This result indicates that the anisotropy is occurred not only in upper mantle but till deeper earth layers, till CMB.

Objektif : Penyakit arteri periper PAP atau periperal artery Disease PAD merupakan penyakit obstruktif pda extremitas bawah yang dihubungkan dengan kondisi kritis iskemik exremitas bawah dengan resiko amputasi. Kegagalan pada penyembuhan luka operasi pasca below knee amputasi adalah multi faktorial, salah satunya ditekankan kepada penilaian kualitas aliran darah pada tingkat level amputasi.Ultrasonografi merupakan alat pemeriksaan yang cukup ideal untuk menilai kondisi arteri pada extermitas, oleh karena itu penelitian ini dilakukan untuk mencari hubungan antara hasil pemeriksaan ultrasonografi dengan kesembuhan luka operasi below knee amputasi extermitas yang nantinya di jadikan indikator prediktif kesembuhan. Metode : Penelitian ini menggunakan studi case control retrospektif untuk mencari hubungan hasil pemeriksaan ultrasonografi peak systolic, diameter, volume flow, spectral wave arteri poplitea, arteri tibia anterior dan arteri tibia posterior pada pasien yang menderita penyakit arteri periper PAP di RSUPN Cipto Mangunkusumo, RSUP Fatmawati dan RSUD Tangerang dari tahun 2015-2017 dengan kesembuhan luka operasi below knee amputasi. Hasil : Dari penelitian yang dilakukan pada 58 pasien pada Arteri Poplitea memiliki nilai mean Peak Systolic Velocity PSV 72,22 11,5 cm/s , diameter 0,52 0,008 cm. dan volume flow 109,3 30 ml/min. Arteri Tibia Anterior memiliki Peak Systolic Velocity PSV rata-rata 45,65 3,5 cm/s, diameter 0,25 0,01 cm dan 47,9 5,2 ml/min. Arteri Tibia Posterior memiliki Peak Systolic Velocity PSV rata-rata 42,6 2,76 cm/s, diameter 0,25 0,01 cm dan 34,07 3,7 ml/menit. Semua hasil pemeriksaan ultrasonografi menujukan hasil yang signifikan dengan kesembuhan p ABSTRACT
Objective Peripheral artery disease PAD is an obstructive disease of lower extremity associated with critical ischemic condition of the lower exremitas with the risk of amputation. Failure in wound healing operations after below knee amputation is multi factorial, one of which is emphasized on the assessment of the quality of blood flow at the level of amputation levels. Ultrasonography is an ideal examination tool to assess the condition of the arteries in the extermitas, therefore this study was conducted to find the relationship between ultrasonografy examination results with wound healing operations below knee amputation extermitas which later on make predictive indicator of healing. Metode This study used a retrospective case control study to investigate the relationship of ultrasound examination results peak systolic, diameter, volume flow, spectral wave popliteal artery, anterior tibial artery and posterior tibial artery in patients with peripheral artery disease PAP at RSUPN Cipto Mangunkusumo, RSUP Fatmawati and RSUD Tangerang from 2015 2017 with wound healing operation below knee amputation. Result From the research conducted on 58 patients in Poplitea Artery has mean value of Peak Systolic Velocity PSV 72,22 11,5 cm s, diameter 0,52 0,008 cm. And the flow volume is 109.3 30 ml min. Anterior Tibia Artery has Peak Systolic Velocity PSV averaging 45.65 3.5 cm s, diameter 0.25 0.01 cm and 47.9 5.2 ml min. Tibia Posterior Artery has Peak Systolic Velocity PSV averaging 42.6 2.76 cm s, diameter 0.25 0.01 cm and 34.07 3.7 ml min. All ultrasound examination results showed significant results with a growth rate of p
