Reducing Ship Resistance

Prof. Yanuar's research focuses on reducing multi-hull vessel resistance (catamarans/trimarans) by leveraging wave interference between hulls to save vessel energy, as well as research on reducing fluid flow resistance in pipes using both active control methods (fluid additives) and passive control methods (pipe geometry and surface roughness variation).

“Indonesia is one of the world's most populous countries with a vast territory. Therefore, it is reasonable for us to continue conducting studies on energy saving.”

Indonesian Shipping Industry Towards International Leadership

Prof. Sunaryo focuses on ship production industry and shipyard management, ship safety, and the maritime environment, including the application of environmentally friendly ship recycling concepts. His research has also produced an Autonomous Surface Vehicle (ASV) innovation for water security and an underwater ROV capable of detecting objects at depths of up to 100 meters, used together with Basarnas (the National Search and Rescue Agency) to support search and rescue operations. Students under his supervision have also achieved success in international competitions such as the Autonomous Marine Vehicle (AMV), Solar Boat Team (SBT), and UI Hydros.

“Indonesia's shipping industry must be the nation's backbone and be the world's leader in the field of shipping technology. Indonesian waters must be free from accidents and environmental pollution.”

Dr. Eng. Ir. Muhammad Arif Budiyanto, S.T., M.T., IPM

Developing an Energy-Saving and Environmentally-Safe Port

Dr. Arif's research focuses on the Green Port concept through efficient electrical energy use in container ports, including energy management in reefer storage yards and gantry cranes. One of his innovations, an Automatic Retractable Roof Shade for reefer container yards, has been proven to reduce daily electrical energy consumption by 7-14% by reducing heat exposure to refrigerated containers.

“With the link-and-match program between the industries and academics, technological needs in the industry can be accommodated by way of academic matters, thus proving it as a policy solution to the government.”

Dr. Eng. Gunawan, S.T., M.T.

Optimizing a Pipe Installation System With Modularization

Dr. Gunawan develops a modularization method for ship engine room piping systems, inspired by modularization principles in the automotive industry, to accelerate ship design and production while reducing costs and the risk of design errors. The research has also produced a computerized system based on genetic algorithms for automatically optimizing component layout and pipe routing.

“When applied to mass production processes, principles of modularization are very powerful since they save time and their results are similar.”

Sea Transportation and Logistics

Achmad Riadi's research focuses on maritime transportation systems and logistics, covering fleet planning, port service optimization, and system dynamics modeling that links port capacity with fleet performance. He also develops AI-based decision support systems (fuzzy systems and neural networks) to more accurately predict demand for maritime transportation services.

“Sea transportation requires an Information and Communications Technology (ICT)-based decision support system to make it more competitive in achieving the goals of successful transportation and logistics services by employing the 7R principles.”

Developing the Optimal Ship Structure and Eco-Friendly Fishing Boat

Dr. Gerry focuses on optimizing ship structural design, from scantling to material selection, to reduce production and operational costs while supporting emission reduction programs. He also develops environmentally friendly fishing boat designs using recyclable steel materials, while introducing electric motor propulsion technology to address the shortage of quality wood.

Materials – Corrosion: Enhance Material Durability and Reduce Maintenance Costs

Dr. Firman's research focuses on the phenomenon of surface corrosion and its impact on structural reliability, particularly in the maritime industry where ship steel structures are exposed to moisture and sea salt. His work includes numerical modeling of corroded surfaces and mitigation strategies such as the use of corrosion-resistant materials, protective coatings, and real-time sensor-based monitoring systems for early corrosion detection.

“The occurrence of surface corrosion has a considerable impact on the performance of materials, resulting in a deterioration of surface integrity and a reduction in lifespan. Consequently, this affects the durability and reliability of industrial applications.”

Centre for Maritime Development (MARDEV): Ocean Sustainable Development Systems

Kurniawan Teguh Waskito develops a cost-effective ocean wave energy converter with a hydraulic power take-off system, integrating wave, solar, and wind energy through the ON-POWER (Ocean POWER) research program to provide clean energy, fresh water, green hydrogen, and local electricity for coastal areas. He also develops the ON-SHIP (Ocean-going Ship High Performance) program to evaluate ship performance in actual sea conditions through weather and wave simulations to support shipping operational efficiency.

Ice Slurry Generator: A Cooling System Using Ice Slurry Media

Dr. Agus S. Pamitran has developed an ice-slurry-based cooling innovation that is highly beneficial for Indonesia's traditional fishermen, who have long relied on ice blocks brought from land to preserve their catch. This seawater-based ice slurry maker reduces fishermen's dependence on ice blocks and makes it easier to produce ice directly at sea, extending the duration of fishing trips. The temperature of the resulting ice slurry can be tuned based on the seawater's salinity, allowing the cooling medium to be adjusted to keep fish fresh according to consumer preference. Besides cooling fish, ice slurry can also serve as a secondary coolant in refrigeration systems, for example to reduce the initial investment cost of cold-storage buildings.
