It is necessary for alternative energy research as a renewable source of electrical power to replace energy sources that cannot be renewed. The one of energy is ocean thermal energy conversion, in which the technology is based on the thermal energy difference between surface temperatures and deepsea water to produce electricity. The research aimed to assess the power potential generated by utilizing the vertical sea temperature in some Indonesian waters. The survey method was used to collect secondary data from the HYbrid Coordinate Ocean Model. The process was completed with the conversion of OTEC to produce the electric base on the model applied by Rauchenstein. This model calculated the net power production of an OTEC plant as a function of water temperature and chilled water pipe length with the potential OTE...

Various efforts have been conducted to rehabilitate the degraded mangroves , yet problems arise when planting mangroves in the high and permanently waterlogged areas in coastline. The aquaponic system is a mangrove planting method introduced to reduce the impact of permanent and high water inundation. This research aims to analyze the survival rate of mangroves planted using vertical and horizontal aquaponic systems in Jakarta's north coast and investigate the correlation between physico-chemical environmental parameters and the survival and growth rates of the planted mangroves. The results showed that the survival rate of mangroves planted in the vertical aquaponic system reached 55.4-96.9%. On the other hand, the highest survival rate in the horizontal aquaponic system was obtained in mangrove planting at 80-100 cm from the bottom with survived plants between 70-90%. The height growth rate of mangroves planted in the aquaponic system was between 0.95-2.33 cm/month. The correlation analysis showed that soil salinity, soil pH and water salinity had a high correlation to support living trees of mangrove seedlings. Rhizophora apiculata, Rhizophora mucronata, and Rhizophora stylosa had highest survival and adaptation in this planting system.

The limitations of energy and electricity in the Riau Islands caused frequent blackouts. To support the high demand for energy and electricity in the Riau Islands, renewable energy is the most suitable alternative energy solution. Renewable energy is not only playing a key role in providing energy but also providing long-term clean and sustainable energy. We investigated the wave energy potential in the Riau Islands Sea in four different consecutive monsoons (North monsoon, East monsoon, South Monsoon and West Monsoon) using ECMWF data during January 2018 to December 2018 with 0.125 o x 0.125 o and 6 hourly spatial and temporal resolutions. We extracted bathymetry data from NOAA’s database ETOPO1 and forecasting wave characteristics use the SPM (Shore Protection Manual) method. The potential wave energy simulation from sig...
