"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."

"In this research the model of earth layers between earthquake's epicenter in Hokkaido Japan and observation station in Black Forest of Observatory (BFO), Germany is investigated. The earth model is 1-D that represents the average speed model. The earth model is obtained by seismogram comparison between data and synthetic seismogram in time domain and three components simultaneously. Synthetic Seismogram is calculated with the Green's function of the Earth by MINor Integration (GEMINI) program, where program's input is initially the earth model IASPEI91, PREMAN and also the Centroid Moment Tensor (CMT) solution of the earthquake. A Butterworth low-pass filter with corner frequency of 20 mHz is imposed to measured and synthetic seismogram. On seismogram comparison we can find unsystematic discrepancies, covering the travel time and waveform of all wave phases, namely on P, S, SS wave and surface wave of Rayleigh and Love. Solution to the above mentioned discrepancies needs correction to the earth structure, that covering the change of earth crust thickness, the gradient of �?�h and value of zero order coefficient in �?�h and �?�v in upper mantle, to get the fitting on the surface wave of Love and Rayleigh. Further correction to accomplish the discrepancies on body waves is conducted on layers beneath upper mantle down to depth of 630 km, where a little change at speed model of P and S wave is carried out. The number of oscillation amount especially on Love wave is influenced by earth crust depth earth. Good fitting is obtained at phase and amplitude of Love wave, but also at amplitude of some body wave too. This effect is not yet been exploited for the determination of moment tensor."

"The seismogram of a deep earthquake,C050296F,has been analyzed at various stations around the quake's epicenter,that are HNR,MSVF,CTAO and SNZO,to investigate the S speed structure below the Ontong -Jawa Plateau (OJP) in Pacific west Equator....."

"ABSTRAKTulisan ini membahas mengenai dinamika salah satu organisasi mahasiswa di Indonesia, yaitu Consentrasi Gerakan Mahasiswa Indonesia atau CGMI pada kurun 1956 ndash; 1965. Dinamika tersebut diharapkan dapat memberi manfaat untuk menelusuri sejarah pergerakan mahasiswa yang terjadi pada masa transisi Demokrasi liberal hingga akhir Demokrasi Terpimpin. Selain itu, diharapkan dapat mengetahui proses terbentuknya CGMI dan dinamika yang terjadi dengan HMI. Metode yang digunakan dalam penulisan ini menggunakan metode sejarah yang terdiri dari heuristik, kritik, interpretasi dan historiografi. Hasil penelitian ini antara lain menunjukkan bahwa, pada awal didirikannya CGMI didasarkan pada persamaan sikap tiga organisasi lokal mahasiswa, yaitu CMJ, CMB, dan GMIB yang menolak inisiasi dalam perguruan tinggi. Pada tahun 1964, CGMI berafiliasi PKI. Terjadinya peristiwa G30S berakibat dengan dibubarkannya CGMI.

ABSTRACTThis paper discusses the dynamics of one of the student organizations in Indonesia, the Concentration of Indonesian Student Movement or CGMI in the period 1956 1965. The dynamics are expected to provide benefits to trace the history of student movements that occurred during the transition of Liberal democracy until the end of Guided Democracy. In addition, it is expected to know the process of CGMI change, from student local organizations to national level organizations as well as the dynamics that occur with HMI due to ideological differences. The method used in this paper uses historical methods consisting of heuristics, criticism, interpretation and historiography. The results of this study, show that, at the beginning of the establishment of CGMI is based on the similarities of attitudes of three local student organizations, namely CMJ, CMB, and GMIB who refused initiation in universities. In 1964, CGMI was affiliated with PKI. The occurrence of G30S events resulted in the disbandment of CGMI."
