About
I'm an early-career data professional with a foundation in geoscience, specializing in turning large, heterogeneous datasets — seismic volumes, well logs, and biostratigraphic records — into clean, structured, and model-ready data. My work spans the full pipeline: ingesting raw subsurface data, validating and cleaning it, integrating it across sources, building statistical and uncertainty models, and translating the results into insight that shapes real decisions. I'm comfortable working in Petrel, OpendTect, TNavigator, and R, and I bring the same rigor to cross-functional collaboration as I do to the data itself. Outside of work, I volunteer on geohazard and disaster-mitigation initiatives.

Experience
Exploration — Subsurface Data Integration
Integrated and interpreted multi-source subsurface data across the Sunda Basin, combining mudlog, wireline log, biostratigraphic, final well report, and 3D seismic datasets in Petrel and OpendTect. Modeled the depositional evolution of the Oligocene Zelda member from a lacustrine–deltaic to fluvial system using palynomorph assemblages, stacking patterns, and lithology descriptions. Applied sequence stratigraphy and HorizonCube-based seismic interpretation to identify sequence boundaries and depositional architecture, improving basin-scale understanding and sediment distribution modeling.
Subsurface Development
Determined the Oil-Water Contact (OWC) in the Menggala Formation, Duri Field, Central Sumatra Basin, by integrating open-hole log, side-wall core, and formation pressure data from 52 wells in Geolog. Delivered field-development optimization recommendations based on the modeled OWC distribution.
Research & Teaching Assistant — Stratigraphy Laboratory
Supported biostratigraphic and stratigraphic data analysis (nannofossils, lithostratigraphy) for regional geological interpretation in Ciletuh, West Java. Supervised 2 classes (8 modules) and led stratigraphy field courses, strengthening students' data interpretation skills.
Research Assistant — Community Service Program (PPM UNPAD 2023)
Conducted engineering-geology mapping in Banyuresmi Village, Sumedang Regency, West Java. Produced geological hazard assessments and mitigation recommendations that improved community awareness of landslide risk.
Student Delegate — International Geomapping Gua Musang (IGGM) 10.0
Ran a 3×3 km geological mapping project in Gua Musang, Kelantan, Malaysia, integrating lithological, structural, and stratigraphic datasets for regional interpretation in ArcGIS. Took part in international academic discussion and collaborative geological analysis, strengthening cross-border scientific exchange.
Awards
WILDCAT AAPG ITB 2024 — Geology & Geophysics (G&G) Case Study, National
Led an integrated prospect evaluation in the North Sea Basin using seismic interpretation and petrophysical analysis in TNavigator, producing a prospective-resource volume estimate that accounted for geological uncertainty and risk.

Volunteering
Landslide Disaster Response Volunteer
Managed incoming donor aid packages at a disaster relief post and coordinated the equitable distribution of more than 1,000 aid packages across affected areas.
