Performance of Multi Chamber Oscillating Water Columns: Effects of Chamber Configuration and Power Absorption Adnan Sandy Dwi Marta, Agus Wibowo, Bondan Fiqi Riyalda, Fuad Darul Muttaqin, Amar Makruf Tinulad Fil Ardli, Amien Rusdiutomo, Wahyu Hendriyono, Affandy Hamid, Qidun Maulana Binu Soesanto, Ristiyanto Adiputra Evergreen, 2026 Oscillating Water Column (OWC) is a promising green energy technology for wave energy conversion, accounting for 26.79% of global wave energy converter applications.This study investigates the hydrodynamic and aerodynamic performance of multi-chamber OWC systems with variations in chamber inclination angles (0, 20, and 40) and the number of chambers (2, 3, and 4).Computational Fluid Dynamics (CFD) simulations were performed using the Reynolds-Averaged Navier-Stokes (RANS) equations and the RNG turbulence model to analyze flow characteristics under regular wave conditions.Key parameters evaluated include free surface elevation, air pressure, air velocity, power distribution, and power absorption.Results indicate that the highest free surface elevation (1.545 m) occurred in a 4-chamber configuration with a 0 inclination.The maximum air pressure (774,804 Pa), air velocity (36.356 m/s), and power distribution (23.58 kWh) were found in a 3-chamber system with a 40 inclination.Meanwhile, the highest total power absorption (42.79 kWh) was observed in a 4-chamber system with a 40 inclination.The 4-chamber configuration with a 40 inclination showed the best performance, achieving 42.79 kWh of power and 0.86 efficiency-outperforming 3-cahmber and 2-chamber setups by 52% and 77%, respectively.Generally, configurations with more chambers resulted in greater power absorption but lower individual pressure and velocity peaks.Increased inclination tends to reduce water surface oscillation.These findings provide insights for optimizing multi-chamber OWC design for improved wave energy capture.
Preliminary assessment of nearshore wave energy in Morotai for remote electrification in Indonesia Hendriyono Wahyu, Wibowo Nugroho Mardi, Saputri Ayu Novitasari, Purwoko Andan Sigit, Ratnasari Esti, et al. International Journal of Applied Science and Engineering, 2026 As one of Indonesia’s outermost islands, North Morotai requires focused infrastructure development, particularly in the renewable energy sector, and this study presents an initial assessment of nearshore wave energy potential around Cape Sopi using numerical modeling. The analysis employed MIKE21 software (by DHI) and utilized 30 years of global wave and wind data from the validated ERA5 model to produce high-resolution annual wave climate data near the coast. Five key sites (Sopi, Totobako, Cape Sopi, Aru, and Loleo) were selected, each with two depth points (5 m and 40 m), to evaluate annual wave conditions and estimate wave energy resources. Results show that dominant wave energy periods across all locations range from 9 to 11 s, with wave heights varying by site: 0.4–0.8 m at Sopi 1; 0.8–1.2 m at Sopi 2 and both Totobako sites; 1.4–2.0 m at Aru and Loleo; and 1.6–2.2 m at Cape Sopi. Cape Sopi emerged as the most energetic site, offering up to 90 MWh/m of wave energy annually, while Sopi 1 (sheltered within Sopi Bay) recorded the lowest, at approximately 12 MWh/m. Seasonally, around 75% of annual wave energy is concentrated between October and March, with the remaining 25% during April to September. The findings provide both technical and strategic contributions to Indonesia’s renewable energy and electrification efforts. The study establishes a validated baseline for nearshore wave energy assessment under local conditions, offering essential input for Wave Energy Converter (WEC) design and supporting evidence-based planning for clean energy deployment in remote islands.

The application of a low-cost microcomputer logger with pressure-temperature based sensor for coastal observations: A preliminary study M Batubara, J Risandi, A Sufyan, A Pamungkas, K S Wardhani, W Hendriyono, S Husrin, Y Ulumuddin, R Hidayat, Handrio, A Ulvan, Muhajirin, F Alfahmi Iop Conference Series Earth and Environmental Science, 2024 Nearshore hydrodynamics, such as water level fluctuations, field observations play a crucial role in understanding and monitoring the dynamics of the coastal region. The observed parameters provide insight into oceanographic processes, climate change impacts, and the behavior of marine ecosystems that could be valuable for coastal management and infrastructure development planning. Most of the available hydrodynamic loggers are provided by companies with relatively high prices. Due to limited budgets, many areas including Indonesia waters, have limited hydrodynamic observation data. In this paper, we presented a prototype of a simple (DIY-Do It Yourself) and low-cost water level logger with a microcomputer that could be applied in coastal regions. The system consists of a pressure-based sensor to detect water level fluctuations, a temperature sensor, a single-board microcomputer and data logger, and a power supply with different sampling frequencies for various coastal applications. The result showed the ability of the microcomputer system to measure high-resolution water levels and temperatures applicable for non-directional waves, tides and non-tides observations, and ecological monitoring. The microcomputer’s low power consumption makes it suitable for long-term coastal observations, even in remote or battery-powered applications. The body of the logger is designed from PVC-nylon with sensors made from waterproof and corrosion-free materials to ensure its applicability for coastal monitoring. Moreover, the flexibility of the microcomputer system allows for customization and adaptation to specific research requirements at relatively affordable prices.
Tsunami Database Development in the Sunda Arc Indonesia to Support Early Warning through Artificial Intelligence Technology Mardi Wibowo, Wahyu Hendriyono, Hanah Khoirunnisa, Reno Arief Rachman, Widjo Kongko, Gugum Gumbira, Shofia Karima, Reni Wijayanti, Eko Kustiyanto, Amalia Nurwijayanti, Destianingrum Ratna Prabawardani, Gumilang Ramadhan Pasma International Journal on Advanced Science Engineering and Information Technology, 2023 The Sunda Arc-Indonesia is very vulnerable to tsunamis. There have been at least 55 tsunamis from 416-2018. Tsunami in the Sunda Arc is classified as a near-field tsunami with an arrival time of < 30 minutes after the earthquake. Meanwhile, the BMKG issued a warning within 5 minutes after the earthquake; therefore, speed in giving warnings is very vital. Artificial intelligence is an alternative technology that can quickly predict a tsunami's height and arrival time. For developing this technology, adequate quality and quantity of data and information on tsunamis are needed. Therefore, this study was conducted to build a tsunami database based on the results of simulations and numerical modeling of multiple scenarios from hypothetical and historical earthquake sources. This study used the open-source TUNAMI F1 model. This model simulates the propagation of tsunami waves using a linear equation. This study obtained 465 hypothetical earthquake sources, 534 historical earthquake sources, and 9,990 datasets from tsunami model simulation results. Each dataset contains ten information. Based on the 8.2 magnitude earthquake scenario, the potential tsunami hazard is 3-47 m with an estimated arrival time of < 30 minutes. An earthquake < 7 Mw can trigger a tsunami, especially an earthquake that is shallow and close to the coast, even though the tsunami height is < 0.5m. This data will be used to train an artificial intelligence-based tsunami prediction system. The artificial intelligence-based tsunami prediction system is expected to be used to strengthen the Indonesia tsunami early warning system (InaTEWS).
Development of Real-Time Tsunami Early Warning System Dashboard Based on Tunami-F1 and Machine Learning in Sunda Arc, Indonesia Dhedy Husada Fajar Pradana, Edwin Adi Wiguna, Amien Rusdiutomo, Ayu Novitasari Saputri, Mardi Wibowo, Wahyu Hendriyono Proceeding 2022 IEEE Ocean Engineering Technology and Innovation Conference Management and Conservation for Sustainable and Resilient Marine and Coastal Resources Oetic 2022, 2022 The majority of tsunamis in Indonesia are nearfield tsunamis, therefore a quick tsunami early warning system is essential to minimize the risk. This study aimed to build a prototype of the dashboard for tsunami early warning systems that can provide tsunami prediction within the first five minutes. This prototype of the dashboard has the main function to predict the occurrence of tsunamis based on hydrodynamic modeling of wave propagation and tsunami artificial intelligence (AI) modeling which runs simultaneously when receiving earthquake data with tsunami potential. The AI model needs just a few seconds to predict tsunami heights and arrival times at affected locations, while the hydrodynamic wave propagation model needs a few minutes to complete the task. However, the results from the latter model are more accurate and complete, such as sea level elevation and the estimated time of arrival. The result of this study shows that the dashboard prototype can quickly and accurately display the results of tsunami predictions by combining the results of the two models. The results and other data are then compiled into a tsunami bulletin and distributed to competent authorities. This study is expected to be used as one of the considerations in developing a dashboard system for tsunami early warning by applying AI in addition to tsunami propagation modeling.
The hydrodynamics condition of water operating area for flight test site selection of N219 Amphibious aircraft H Khoirunnisa, M Wibowo, W Hendriyono, K S Wardani Iop Conference Series Earth and Environmental Science, 2021 This research aims to assess the hydrodynamics condition of the water area for site selection of that purpose. The bathymetry data of Karimunjawa Island were obtained from the 1986 Pushidrosal bathymetric map. Furthermore, wind direction, wind speed, wave height and direction, and tidal data around the waters of Karimunjawa Island were input in hydrodynamic and spectral modelling using MIKE 21 HD-SW. West monsoon and east monsoon were applied in this model. The validation result between hydrodynamic modelling and Tidal Model Driver (TMD) data is 98.89%. The surface elevation around the domain has a range of 0.072 - 0.5 m. The average water depth at the seaplane dock plan is about 2.5 m from MSL. The hydrodynamic modeling results show that the surface elevation value at the seaplane dock plan location shows that the sea level is between -0.467 to 0.473 m (in both west and east season). The current velocity at the planned seaplane dock site in both the west and east monsoons is relatively slow (<0.185 m/s). The dominant wave direction is southeastward in the east and west monsoons. The dominant Hs is about 0.23 – 0.6 m in both seasons. At the planned water operating area, the average of Hs is 0.23 m - 0.36 m. Generally, this location fulfills the criteria of site selection for the flight test location of N219A.
