Optimalisasi Peranan Ekologis Anggur Laut Caulerpa racemosa pada Lingkungn Pesisir Dengan Tekno-Akuakultur Berkelanjutan

Environmental problems such as global warming, oxygen crisis and carbon stock, and pollution are difficult to solve. This problem has a very broad impact on various sectors such as the ecology, economy, social community, health but is difficult to solve because it coincides with meeting the needs of various scales. Coastal fishing communities whose lives depend on nature certainly have the greatest impact on coastal areas, so it is necessary to find preventive solutions that are integrated with various sectors. The use of local commodities to help solve integrated problems such as C.racemosa can be a strategic solution. This study aims to determine the existing conditions, the benefits of all environmental aspects and determine the design of cultivation technology and how to apply it in coastal ecosystems.
Method: This research was conducted in the waters of Bintan Island, Riau Islands using a mixed method (mixed method) which was carried out for 10 months. The aspects observed were the existing condition of C.racemosa and its habitat, the benefits in the environment and the socio-cultural conditions of the community that made C.racemosa a livelihood. Then the existing condition data is identified looking for solutions in the form of applied technology that integrates all aspects of the problem in an effort to provide easy, cheap and sustainable solutions.
Results: The results of the research on the existing conditions showed that the natural condition of C.racemosa was in low cover conditions, namely 23-43% and productivity 0.40 kg/m2. This condition, if exploited in a sustainable manner, will threaten its existence even to the point of extinction, in addition to suppressing the pollution that occurs in the waters. For the benefit of C.racemosa, it has the ability to supply oxygen to the waters of 1.44 mg/lt with a carbon stock of 118.75 kg/Ha and has the ability as a phytoremediator agent with an accumulation power of 728-6240 times for Cd metal and up to 3630.8 times for metal. Pb when compared with the content in the waters until a certain time phase includes other metals such as Cu, Fe and Zn. C racemosa also provides benefits to other organisms in the ecosystem called symbiotic associations, both parasitism with a value of 17.4 ind/m2, mutualism 12.5 ind/m2 and commensalism 37.2 ind/m2. Furthermore, C.racemosa also has economic and socio-cultural benefits, where there are 54 fishermen who make C.racemosa a livelihood, with an income level still below the Riau Islands minimum wage, which is 62.34% still earning below 2 million

every month. The education level of 74.08% is still educated up to junior high school, this is due to the limited ability of natural productivity and the impact of environmental pollution so that it has implications for the economic and socio-cultural aspects of the community.
Method novelty: The novelty of the method in this study is the method of cover identification which is the result of a modification of the CPCA (Coral Percentage Cover Analysis) software which is intended to analyze coral reefs, so in this study it was applied to analyze the cover of C.racemosa which is called Caulerpa Percentage Cover Analysis. This method has a higher accuracy than the usual method because the calculations are not observed manually which can be influenced by the subjective element of the researcher.
Technological Novelty: The technological novelty that is produced is called Enviteg Aquafarm (Environmental Integrated Aquaculture Farming), where this technology makes ecological, economic, social and cultural aspects as key parameters for assessing its feasibility. Enviteg Aquafarm technology can be implemented easily and cheaply either on a small scale (People's Economy) or Global (Fishing industry) or only used as a barrier for environmental recovery (bioremediation, oxygen supply and carbon reserves).
Theoretical Novelty: The concept of Enviteg Aquafarm Cultivation is the result of a mixture of ecological benefits called Phytoecological species, Economic benefits called Phytoeconomical species, Social benefits called Phytosocialical species and cultural benefits called Phytoculturalical species. These four benefits must be owned by the species so that they can be called Phytoenvironmentalical Species that can be used in Enviteg Aquafarm Cultivation technology. One of the species that meet these criteria is C.racemosa.
Conclusion: The existing condition of C.racemosa in the coastal waters of Bintan Island is in a low condition both in terms of productivity, quality, quantity, and percentage of cover, so that it has a wide impact on environmental aspects (ecological, economic, social and cultural of the fishing community of Bintan Island. C.racemosa has ecological, economic, social and cultural benefits but unfavorable natural conditions require technology for sustainable development Enviteg Aquafarm technology (Environmental Integrated Aquaculture Farming) is a technology designed in an integrated manner (economic, social and cultural ecology) to help solve the problem of using C.racemosa in nature.This technology is able to help optimize the role of C.racemosa in its living ecosystem.
