Conservation Constraints and Distributed Advective Memory in a Reduced Model of Atlantic Overturning Hysteresis
Sandy Hardian Susanto Herho, Iwan Pramesti Anwar, Mutiara Rachmat Putri +3
Interbasin exchange through the Indo-Pacific gateway supplies salt to the Atlantic and is widely invoked as a control on the stability of the Atlantic overturning circulation. We a…
An Idealized Delay-Differential Model of Scuba Diver Porpoising and Runaway Ascent
Sandy Hardian Susanto Herho, Faizal Ade Rahmahuddin Abdullah, Iwan Pramesti Anwar +5
A scuba diver holding constant depth balances on an unstable equilibrium: the gas carried in the suit and buoyancy compensator compresses with depth, so the buoyant force falls as…
Preliminary sonification of ENSO using traditional Javanese gamelan scales
Sandy Hardian Susanto Herho, Rusmawan Suwarman, Nurjanna Joko Trilaksono +2
Sonification -- the mapping of data to non-speech audio -- offers an underexplored channel for representing complex dynamical systems. We treat El Niño-Southern Oscillation (ENSO),…
Causal Attribution of Coastal Water Clarity Degradation to Nickel Processing Expansion at the Indonesia Morowali Industrial Park, Sulawesi
Sandy Hardian Susanto Herho, Alfita Puspa Handayani, Iwan Pramesti Anwar +5
Indonesia's nickel ore export ban has driven rapid expansion of smelting and hydrometallurgical processing capacity at the Indonesia Morowali Industrial Park (IMIP), now the world'…
dewi-kadita: A Python Library for Idealized Fish Schooling Simulation with Entropy-Based Diagnostics
Sandy H. S. Herho, Iwan P. Anwar, Faruq Khadami +5
Collective motion in fish schools exemplifies emergent self-organization in active matter systems, yet computational tools for simulating and analyzing these dynamics remain fragme…
Numba-Accelerated 2D Diffusion-Limited Aggregation: Implementation and Fractal Characterization
Sandy H. S. Herho, Faiz R. Fajary, Iwan P. Anwar +4
We present dla-ideal-solver, a high-performance framework for simulating two-dimensional Diffusion-Limited Aggregation (DLA) using Numba-accelerated Python. By leveraging just-in-t…
1d-qt-ideal-solver: 1D Idealized Quantum Tunneling Solver with Absorbing Boundaries
Sandy Hardian Susanto Herho, Sito Fossy Biosa, Siti Nurzannah Kaban +4
We present 1d-qt-ideal-solver, an open-source Python library for simulating one-dimensional quantum tunneling dynamics under idealized coherent conditions. The solver implements th…
\texttt{simple-idealized-1d-nlse}: Pseudo-Spectral Solver for the 1D Nonlinear Schrödinger Equation
Sandy H. S. Herho, Iwan P. Anwar, Faruq Khadami +2
We present an open-source Python implementation of an idealized high-order pseudo-spectral solver for the one-dimensional nonlinear Schrödinger equation (NLSE). The solver combines…
rd-spiral: An open-source Python library for learning 2D reaction-diffusion dynamics through pseudo-spectral method
Sandy H. S. Herho, Iwan P. Anwar, Rusmawan Suwarman
We introduce rd-spiral, an open-source Python library for simulating 2D reaction-diffusion systems using pseudo-spectral methods. The framework combines FFT-based spatial discretiz…
An Early Development of Flood Inundation Mapping Method Using Free Android Application to Support Emergency Response Activities: Case Study Baleendah, Bandung, West Java
Sandy Hardian Susanto Herho, Edi Riawan, Cahya Nugraha +3
This study aims to simplify the current flood mapping methodology, so it can be done in quicker time, easy to learn, but still produce accurate flood information to support the eme…
