Unfiltered explorations, ideas, and occasional wisdom
After years of keeping notes to myself, I decided it was time to share my thoughts with the world.
Open science is more than just open access papers. It's a fundamental shift in how we do research.
Academic work, open-source projects, and research notes from ongoing investigations
An interactive 16-slide deck on cross-region transfer of a pretrained U-Net for landslide detection. Validated on Garut and Sukabumi (West Java) against 85 PVMBG field-investigated events: 100% within 1 km, ~90× signal above random — with no region-specific labels.
This study addresses the critical need for accessible and cost-effective LULC training data collection by developing an innovative system that utilizes consumer-grade dashcams with GPS capabilities to generate georeferenced video datasets.
This study investigates the correlations between human-modified landscape structures and bird diversity in the Paseh Sub-district, Sumedang District, West Java, Indonesia.
A visual guide explaining the back propagation algorithm used in training neural networks.
Exploring techniques for identifying and mapping rice fields using satellite remote sensing data.
Monitoring rice crop growth stages through multi-temporal satellite imagery analysis.
This study presents a comparative analysis of two methods for land cover classification: machine learning using Google Earth Engine and time-series imagery using R's sits package.
