Spall Failure of Coral Skeleton beneath Gas-Laden Canopies: An Idealized Blast-Fishing Model
Sandy Hardian Susanto Herho, Agus Wahyu Jatmiko, Rizki Dimas Permana +7
Improvised explosives used for fishing on shallow Indonesian reefs shatter coral skeleton, yet the damage they cause has been described largely through empirical radii and ecologic…
An Exactly Solvable Ekman Layer with a Fractional-Order Stress Closure
Sandy Hardian Susanto Herho, Rizki Dimas Permana, Iwan Pramesti Anwar +3
The classical theory of the wind-driven surface layer of a rotating ocean closes the momentum balance with a local flux-gradient law, in which the turbulent stress at a given depth…
anyakrakusuma: A Python Library for Entropic Schrödinger Bridges on Idealized Geometries
Dasapta Erwin Irawan, Sandy Hardian Susanto Herho, Agus Wahyu Jatmiko +7
We present anyakrakusuma, an open-source Python library that solves the discrete static Schrödinger bridge problem, the entropically regularized counterpart of optimal transport, t…
amerta: A Python Library for Idealized 1D Saint--Venant Dam-Break Simulation
Dasapta E. Irawan, Sandy H. S. Herho, Iwan P. Anwar +6
The Saint-Venant shallow water equations (SWE) govern depth-integrated free-surface flows arising in dam-break inundation, flood routing, tsunami runup, and estuarine tidal dynamic…
Three-Dimensional Variational Data Assimilation with Rapid Update Cycling for Short-Range Precipitation Forecasting: A Case Study of Heavy Rainfall in Bali, Indonesia
Nurjanna Joko Trilaksono, Sandy Hardian Susanto Herho, I Putu Ferry Wistika +3
This study evaluates the effectiveness of three-dimensional variational (3D-Var) data assimilation coupled with a Rapid Update Cycle (RUC) framework for improving short-range preci…
Measuring Primitive Accumulation: An Information-Theoretic Approach to Capitalist Enclosure in PIK2, Indonesia
Sandy Hardian Susanto Herho, Alfita Puspa Handayani, Karina Aprilia Sujatmiko +5
Large-scale land enclosure for speculative mega-development constitutes a non-equilibrium spatial process whose velocity, topology, and irreversibility remain poorly quantified. We…
