Message

At Geoseismal Research Center, I collaborate on backend systems for geophysical software and develop algorithms for data processing and visualization. I also work on validating data and models to support reliable geophysical analysis.

On SPECTRAGAMA v4.0 for PT. Pertamina Hulu Energi, Upstream Innovation, I designed and implemented a MASW processing algorithm spanning preprocessing, dispersion analysis, 1D Vs inversion, and pseudo-2D subsurface imaging.

For PT. Pertamina, Research & Technology Innovation, I developed magnetotelluric processing and modeling algorithms in Python for subsurface electrical conductivity analysis. I also designed a 3D forward and inverse modeling algorithm for magnetic data in PERTAGAMANT v2.0.

My geophysics degree from Universitas Gadjah Mada included a thesis comparing finite-difference orders for full waveform inversion using the Sleipner carbon capture storage synthetic model and Devito. I’ve also assisted with GPR field data acquisition and student instruction.
