Mangrove has ability to absorb, accumulate, and translocate heavy metal contaminant. Whereas the clustering and landscape of mangrove ecosystem show the grading and zoning of mangrove vegetation to accumulate heavymetal pollution. .Therefore, this study aimed to analyze distribution and clustering of heavy metal accumulation and traslocation in mangrove ecosystem.. The results showed the accumulation of Mercury were 0.1347 ± 0.0212 ppm (sediment), 0.0137 ± 0.0137 ppm (water), 0.0110–0.0640 ppm (stem and bark), 0.0020–0.0120 ppm (leaves), and 0.0260–0.0690 ppm (roots). Cadmium accumulations between 1.6048 ± 0.3595 ppm (sediment), 0.0292 ± 0.0047 ppm (water), 0.0790–0.2650 ppm (stem and bark), 0.0130–0.0480 ppm (leaves), and 0.1560–0.2300 ppm (roots). Furthermore, Zinc had score that were 35.1746 ± 5.4856 ppm (sediment), 0.0550 ± 0.0095 ppm (water), 10.3250–32.4490 ppm (st...

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...

The carbon conservation of mangrove ecosystem supports the growth of mangrove vegetation based on the carbon percent of mangrove stage consisting of mangrove seedling, sapling and mangrove trees. This paper aimed to analyze carbon percentage of mangrove ecosystem which is SNI 06-3730-1995 and TAPPI T 211 om 85 methods and to analysis mangrove clustering based on carbon percentage. The results showed that (1) Avicennia spp, Sonneratia spp, Bruguiera spp, Rhizophora spp, Aegiceras spp, Lumnitzera spp, Ceriop spp, Exoecaria agallocha and Xylocarpus granatum had carbon percentage between 45.01%-55.54%; (2) the carbon percentage of the mangrove growth were seedling (16.3-21.2%), sapling (19.0-28.1%), trees with diameter 10-20 (38.1-46.3%), trees with diameter 20-30 cm (40.2-51.1 %) and trees with diameter 30-40 cm (49,1-55,2 %). The carbon conservation has a positive correlation with the ability of carbon sequestration and mangrove growth. We would like to express our sincere gratitude to UNSOED grant that supported this research.

The research was conducted in Segara Anakan Lagoon to analysis community structure and mangrove landscape based on species distribution, biodiversity, environment factors, and mangrove zoning. The results showed that (a) Segara Anakan Lagoon had 4 mangrove zone's were dominated by Sonneratia alba, Rhizophora mucronata, Avicennia marina, Rhizophora apiculata, Rhizophora styllosa, and Nypa frutican; (b) the structure of ecosystem was showed by trend of mangrove ecosystem with equation y = 35.34x2 923.85x + 12817 with x = time (year) and y = mangrove area (ha), mangrove density between 1333367 ind ha-1 (West Segara Anakan) and 899–567 ind ha-1 (East Segara Anakan), dominated species were Nypa frutican, Rhizophora stylosa, Rhizophora apiculata, and Aegiceras corniculatum...

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...
