Abstract

The coral reef is the most productive marine ecosystem in coastal waters. The primary productivity may reach up to more than 10 kg C/m2/year. This resulted in a high number of fisheries production, such as fishes, shrimps, lobster, mollusc (shellfish), turtle, and others.  Unfortunately, this condition has already suffered from non-sustainable human use including destructive fishing practices (bombing and cyanide), coral mining, over fishing, settlement pollution and uncontrolled tourism development. These affected the production of those fisheries resources in coral reefs. In order to manage those resources, such alternative to destructive use need to be studied. This paper reports alternatives to destructive fishing practices  on coral reefs. The study had been carried out at Taka Bonerate Marine National Park, the District of Selayar, South Sulawesi province,  for about 3 weeks, 7-26 November 2000.  Survey method was used during the study.  The data were collected using Participatory Rapid Appraisal (PRA)’s method, with members of fisher group as the participants. Three kinds of reef fish groups are identified at the Taka Bonerate Islands waters, i.e. major group, target group, and indicator group. These include ornamental and consumption fishes.  These were caught with several fishing gears, while some of them are identified as destructive fishing practices, e.g. bomb, cyanide fishing. However, some of them can be recommended as sustainable fishing technologies, i.e. (1) pancing cumi-cumi, (2) pancing tonda, and (3) samba/kulambi.

Abstract

Dispersion modeling of natural radionuclides 238U, 232Th, 226Ra, 40K in Muria coastal waters has been carried out in sea water and sediment surounding Tanjungjati B coal-fire power plant and nuclear power plant site’s candidate by applying the hydrodynamics model of unsteady 2-dimensional flexible grid. Oceanography data collecting of bathimetry, current, wave, tide and wind had been carried out on May 28, 2006 until June 2006. Updating data was conducted on April 27 up to April 29, 2011 by using Acoustic Doppler Current Meter Profiler (ADCP) to measure the wave and subsurface current with duration of 2x24 hours. Sea water and sediment samples were collected on April 22, 2011 in six locations (surounding Tanjungjati CPP) and on April 23, 2011 in 10 locations (surounding NPP site’s candidate). Samples were analyzed at Research Center for Safety Technology and Radiation Metrology Laboratory, National Nuclear Energy Agency, Jakarta on May 2011 until September 2011 by using spectrometri-γ analysis. Result shows that it can be identified and measured the natural radionuclides of 238U, 232Th, 226Ra, 40K in sea water and sediment. The study can be justified that natural radionuclides of 238U, 232Th, 226Ra, 40K was leachated from fly ash and bottom ash of coal burned Tanjungjati CPP to sea water. The hiyrodynamics model of unsteady 2-dimensional fexible grid by using CD Oceanography software for current plotting, ArcView GIS 3.3 software for bathimetric contouring and SMS 8.1 software for modeling of natural radionuclides dispersion in coastal waters one can applied for radionuclides dispersion of 238U, 232Th, 226Ra, 40K in Muria coastal waters.
