“…Karst area is also widespread in West Java, such as Ciampea and Ciseeng region, with uniqueness of some karst water that the salinity could reach about 30-35 ppt, such as Ciseeng karst water [24]. Salinity is a limiting element in the culture of marine microalgae.…”

Karst water concocted culture medium which contains high concentration of complex minerals was presumed to support production of microalgae, such as Spirulina sp. (Arthrospira sp.), Chlorella sp., and Nannochloropsis sp. This study aims to evaluate the potential of enriched karst water medium to grow Spirulina sp., Chlorella sp., and Nannochloropsis sp. There were two batches of culture with different treatments of nutrient supplementary; the first was for Spirulina sp. and the second was for Chlorella sp. and Nannochloropsis sp. The results showed that all treatments were suitable for Spirulina sp. with different growth rates. The medium with 20:1 N/P ratio showed the best productivity for Chlorella sp., and 10:1 N/P ratio for Nannochloropsis sp. The pure karst water and all level as the nutrient modified karst water media showed a relatively similar growth rate of Spirulina sp. Furthermore, in the best medium for Chlorella sp. and Nannochloropsis sp. gave increasing density until the end of observation, instead of a death phase of commercial addition batch culture. Generally, modified karst water has the potential to be used as the microalgae growing medium.

The coastal area of East Lingga Subdistrict, Lingga Regency has been designated by the Lingga Regency government as the center for the development of shrimp pond cultivation. This study aims to determine the level of toxicity of the surfactant alkyl sulfate (AS) detergent to post larvae (PL) of Vannamei shrimp (Litopenaeus vannamei). An acute test was performed on PL10 samples exposed to AS media for 96 hours. Then the Median Lethal Concentration (LC50) value was calculated for 4 times (24 hours, 48 hours, 72 hours, and 96 hours). Furthermore, the PL-15 sample was AS in the sub chronic test, then the sample was exposed to AS media for 24 hours, then the growth rate and changes in the gill organ structure of the PL samples were observed. From the test results, it is known that the LC50 values in the AS test for the 24th, 48th, 72th, and 96th times of the shrimp larvae samples obtained LS50 values were 33.6 mg/l, 29.4 mg/l, respectively. 24.3 mg/l, and 22.8 mg/l. Subsequently, an increase in AS concentration by 17.11 mg/l in the rearing medium resulted in a decrease in the growth rate of post larvae. The acute and sub chronic testing period showed changes in the behavior of post-larvae samples. The histopathological observations found damage to the structure of the sample gill organs and hepatopancreas. Symptoms of damage to the structure of the gills began to appear at AS concentrations of 25.58 mg/l at time 96 and 72 with an LC50 value of 34.99 mg/l. Furthermore, it was also seen at an AS concentration of 9.78 mg/l at time 24. The results of this study found that AS toxicity to Vannamei larvae increased with increasing concentration and exposure time.
