Abstract

There are several types of water mixing in the estuary, as anexample is tuntang river which could be a model in the coast of northjava island.The aims of this research are known, the spatial distribution of physical structure, organic matter, including he content ofNitrogene and phosphor in the sediment. Further more the role of physical and chemical sediment are also evaluated. The researchwas conducted in of May 2014, in an area which devided into 11 stations : one of them is located before the esturary while in thewest, north west, east and north east the station are distributed proportionally. The variables measured are total organic matters,total nitrogen, total phosphate, NO3-N, PO4-P , Dissolved oxygen, current, depth and visibility. The result of the research shown thatspatial distribution of the sediment strongly suggest the form of clay in front of estuary, south westward as well as north westwards.Clay distribution is well influenced by organic matter and nitrogene while phosphate content tend to be randomly distributed. In thecase of the the current is weak while the oxygen content is high enough so that the relationship between nitrogen and sediment of claycontribute to the water environment condition as eutrophic status.Keywords : Aquatic Productivity, Sediment, NO3, PO4, Tuntang River

Abstract

Inter-host translocation technique of zooxanthellae was attempted to prove Buddemier and Futin’s (1993) theory on adaptation. The recent trend of coral products trading must be anticipated by its mass production through artificial techniques, the alternation of natural resources. Translocation bio-technique of zooxanthellae on coral was expected to resolve the problem and the translocation study should provide fundamental answer to coral recovery. The study of zooxanthellae translocation was proposed to: a) Evaluate the effect of zooxanthellae enrichment on its translocation on coral polyp tissue efter optimum bleaching and b) Investigate the effect of translocation on coral growth. The research was experimental, involving coral species Goneastrea aspera, and purified zooxanthellae clade A, B and C with circulating incubation condition in BPBBAP Jepara indoor area. The experiment took place for 30 weeks in both model environment waters and natural environment waters of Jepara Panjang Island coral area from March to August 2008. The result showed that: a) In the artificial waters, translocation zooxanthellae to polyp tissue of Goneastrea aspera occured at day 17 and more fast in the natural waters; b) In the controlling of temperature environment on translocation provided positive response of Goneastrea aspera’s normal life, relocation and growth rate of zooxanthellae as in nature and c) recognition, resettlement, and growth process of zooxanthellae made it possible for Goneastrea aspera to grow normally in natural waters.   Key words: Clade, bleaching, recognition, resettlement, growth, translocation, zooxanthellae, Goneastrea aspera
