ANALISIS PREDIKSI KERUSAKAN PERKERASAN LENTUR BERBASIS IRI (INTERNATIONAL ROUGHNESS INDEX) DENGAN METODE IRMS-V3, RONET

Jurnal Syntax Transformation, 2023
The condition of road pavement is going to decrease during its service life. To keep a pavement functioning, maintenance must be continuously performed. However, the maintenance that has been carried out so far has not been carried out optimally because the budgeting system is still carried out annually based on the results of a road condition survey ...

THE ASSESSMENT OF NATIONAL ROAD SURFACE CONDITIONS ANALYSIS BASED ON THE INTERNATIONAL ROUGHNESS INDEX (IRI) METHOD USING ROADBUMP APPLICATION

Jurnal Teknik Sipil, 2023
Roads are infrastructure that has a vital role for the community in supporting social and economic activities. Therefore, appropriate handling information is needed for road maintenance and improvement to be on target. One of the methods used is the International Roughness Index (IRI) method with the help of the Road bump application.

Assessing GNSS Reflectometry for High‐Latitude 3D Ionospheric Imaging

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract This study investigates whether Global Navigation Satellite System Reflectometry (GNSS‐R) measurements from low‐Earth‐orbit (LEO) satellites can improve three‐dimensional (3D) ionospheric electron density imaging, with a focus on high‐latitude regions. Conventional ionospheric tomography is limited by sparse ground‐based receiver coverage over

Linking Probabilistic Forecast Reliability to the Mismatch Between Model–Observation and Model–Model Correlations in Dynamical Seasonal Prediction

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Reliability is central to probabilistic forecast skill, and linking it to nonprobabilistic diagnostics is essential for interpreting its behavior and deficits. Although recent studies have suggested a possible relationship between reliability in dynamical seasonal prediction and the mismatch between model–observation correlation (r $r$) and ...
