“…Wave energy converter (WEC) with the oscillating body has the arrangement to transfer the wave motion from the buoy to electrical generator through mechanical arrangements [5][6]. The over topping WEC have simple construction and utilizes the run-off water above the water reservoir to drive a turbine [7][8].…”

In this work, a novel design of an oscillating body-type Wave Energy Converter (WEC) is proposed with an efficiency of 48.73 %. Innovative features of the new design include the integration of Mechanical Motion Rectifier (MMR), Motion Regulator (MR), Energy Storage Element (ESE), and Electric Generator (EG) with the operation controlled by a microcontroller, limit switches, and linear actuator. Lab experiments conducted with a prototype ensured a peak voltage of 8.1 V and peak power of 4.3 W. Experimental and MATLAB theoretical simulation results demonstrated the average power of 55.2-148.3 mW for a wave height of 50-125 mm. In comparison to the conventional operation, where the electric generator is directly driven by wave motion, the proposed design will ensure higher peak power and better energy utilization characteristics of the generated voltage waveform. Simulation results are presented with the incorporation of non-circular gears that ensure modification of the voltage waveform for better energy utilization.

“…With the increasingly real threat of the climate crisis, a commitment is needed to reduce the amount of emissions entering the environment. One step to avoid emissions is the energy transition, namely changing dependence from fossil fuels to other, cleaner energy sources (Vidura Ahmad, 2022). This type of marine power plant is not only environmentally friendly, but also does not damage the natural ecosystem during its construction and operation, so it can continue to be used as a tourist attraction, which also contributes to the economy of the local community (I Wayan Arta, 2010).…”

Utilization of renewable energy is by utilizing the available natural potential. One of them is the use of the sea as an electrical energy generator. With the increasingly real threat of the climate crisis, a commitment is needed to reduce the amount of emissions entering the environment. Utilization of the potential of marine power plants is still very minimal compared to other clean energy plants. The use of marine power plants is also still in the research stage and there is no commercial use yet. This is due to several obstacles. The main obstacle is that the funds needed to build a marine power plant are quite large and the lack of adequate technology for converting marine power into electricity. In writing this article using qualitative methods. Qualitative methods are research methods that intend to understand the phenomena discussed by the research subjects. By using a Literature Review to obtain data that will be the topic discussed in this writing. From various locations that are considered to provide potential such as Larantuka, Selayar Islands, Bali, Flores Island, Adonara Island, Toyapakeh Waters in Nusa Penida Bali and the Jeneponto Sea, and of course there are still many coastal areas that have potential as generators but have not yet been detected as capable. produces electrical energy that is comparable to other renewable generators and can contribute to meeting the country's primary electricity needs. The energy results obtained do not contribute to carbon emissions or are in the clean energy category and the tariff for the electricity produced is still affordable

“…Hydrodynamic modeling in the Seribu Islands was also carried out by [14] around Semak Daun Lagoon using MIKE 21 with the results that the current velocity around the area is influenced by tides. Based on research conducted by [15], the ocean waves in Pari Island are classified as the smooth sea with the range of significant wave height is 0.16 to 0.51 m and it has the wave period range of 2 to 4 seconds.…”

The flight test of N219 Amphibious aircraft will be targeted in 2003/2024. For flight tests, these aircraft need a seaplane dock. One of the potential locations for the seaplane dock is Panjang Island at Seribu Islands. This study aims to know the characteristic of hydrodynamic and wave conditions and to determine whether Panjang Island is suitable for the seaplane dock. This study uses a modeling method with MIKE 21 FM HD-SW module and MIKE 21 Boussinesq Wave (BW) module. The bathymetry data were obtained from the Indonesian Navy Hydrographic and Oceanographic Center (Pushidrosal), tide data is generated from Tide Model Driver (TMD), wave and wind data from ECMWF. The result of surface elevation validation between hydrodynamic modeling and TMD is 92%. During the west monsoon and spring conditions, the difference in the largest and lowest current velocity is quite large (0.018-0.199 m/s), on the other hand, when the tides are in neap conditions (0.008-0.144 m/s). Meanwhile, during the east monsoon and spring conditions, the difference in the largest and lowest current velocities is quite large (0.02-0.193 m/s), on the other hand, when the tides are in neap conditions (0.008-0.146 m/s). The maximum wave height resulting from the 50-year return period waveform modeling between 1.139 - 1.474 m. Meanwhile, the significant wave heights between 0.679 - 0.741 with a significant wave period of 13.45 seconds. In general, the current and wave conditions of the two locations are suitable for the construction of the seaplane dock, except that the dominant wave heights are still above the requirements.
