Abstract

Abstract The increasing of Jakarta land activies caused eutrophication, so that it changes species composition and decreasing of number of species. The sea within the high of eutrophication has correlation with the high growth of alga, depletion of oxygen and change of coral species composition. These researchs was done at coral reef ecosystem of Lancang Island, Pari Island and Payung Island, whereas there are part of Seribu Island Cluster. The aims of research was evaluating of nutrient enrichment effect to morphology and functional of coral reef condition. Morphology figures are showed by basic cover, whereas functional aspects are evaluated by zooxanthellae density. The results are showed that the high eutrophication is significantly correlated with main land of Java Island distance. The increasing of nutrient enrichment is significantly to change profile of coral reef and zooxanthellae densities.

Abstract

Abstract Gracilaria verrucosa is one of the most potential seaweed and consist of a high economy value. G. verrucosa had been succed cultivated in pond and it produces gel (Lewmanomont, 1995). Gracilaria cultivation in pond generally needs a wide area, easily infected by moss and shellfish so that obstructs Gracilaria's growth, even decreases it's quality (Aslan, 1998). One of the solution to solve the problem above is cultivate another seaweed G. verrucosa indoor using the combination of NPK and TSP. NPK and TSP are used to increase growth and formation of chlorophyll a which used to fotosintesis process (Anggadiredja dkk., 2006). The absortion of hara element will add nutrient and influenced to the G. verrucosa's quality and quantity. This research uses water concentration measuring because gel content measuring is relatively expensive. The goal of this research is knowing the influence of NPK and TSP to G. verrucosa's growth, water concentration and quantity of chlorophyll a. The result of G. verrocosa shows that daily growth heavy of G. verrocosa in D treatment extremely different (p<0,05) with A, B, C, E and F treatments. The best daily growth heavy of G. verrocosa is in D treatment and the lowest daily growth heavy of G. verrocosa is in A treatment. The result growth length shows that in D treatment extremely different (p<0,05) with A, B, C, E and F treatment. The best growth length is in D treatment and the lowest growth length is in A treatment. The result G. verrucosa's water concentration shows that in C, D and E treatment extremely different (p<0,05) with A, B and F treatment. The best water concentration is in C, D and E treatment. The lowest water concentration is in A, B and F treatment. The result chlorophyll a quantity shows that in B, C, D E and F treatment extremely different (p<0,05) with A treatment. The best G. verrucosa's chlorophyll a quantity is in B, C, D, E and F treatment. The lowest G. verrucosa's chlorophyll a quantity is in A treatment. The conclusion of this research is the combination of NPK and TSP in G. verrucosa seaweed cultivation extremely affect the growth, water concentration and chlorophyll a G. verrucosa with the best dose is 2 g/l and the ratio NPK and TSP is 50%:50%.

Abstract

Abstract The higher toxicity of α-linolenic acid from Ulva sp. seaweed showed the high algicidal activity against Chattonella marina and Heterosigma akashiwo. Among six species tested, C. marina and H. akashiwo was the most susceptible to this fatty acid, whereas LC50 of α-linolenic acid was estimated to be 3.22 and 0.58 µg/mL, respectively. Furthermore, α-linolenic acid also showed algicidal activity against Alexandrium tamarense and A. taylori. It is suggested that α-linolenic acid is useful mitigation agents to Harmful Algal Bloom effect, especially on Chattonella marina and Heterosigma akashiwo.
