Abstract

Enhalus acoroides is water plant intertidal that might be interaction between ecosystem eachother so it have ability to adsorb heavy metal that came from sea water and sediment that can accumulated in roots, leaf and bar ponder. Variation methods used to know distribution of meiofauna as intertitial fauna or epiphytic fauna on seagrass. The concentration of heavy metal of water, sediment and meiofana will be analyzed. The purpose of this research to determined correlation between concentration in seagrass, sediment, water and organism which associated whitin. The result of this research shown that  concentration of heavy metal Cu, Cd and Pb have a significant correlation between water, sediment, part of seagrass and meiofauna. The value of R2 shown that correlation between water and sediment have bigest value, otherwise the  R2 value of heavy metal shown that Pb is the biggest than Cd and Cu. Concentration heavy metal in seagrass shown that Cu>Cd>Pb and the same condition is also due in meiofauna. Its mean that the heavy metal is bioavailble for accumulation by meiofauna. Meifauna and segrass can be a good bioindicator for environmenta change especially heavy metal.

Abstract

Pond bottom  management play  an important role in the success of shrimp culture. Study on the     use of pond bottom pond as an indicator of shrimp pond productivity is still limitted.   Shrimp culture has been developing in tulang Bawang Regency, Province of Lampung since early 1990.  The waste produced by shrimp culture activity is possible to reduce pond bottom soil quality due to high organic compund and toxic material. The aim of this research was to evaluate the shrimp ponds bottom condition in Tulang Bawang Regency, Province of Lampung.  This research was an explorative one.  Data collection was done towards 12 shrimp pond units during water preparation period (pre-spreading) with the different locations of each pond from the watergate. The collected data of pond soil qualities were organic matter content, chlorophyll a, cation exchange capacity, oxidation-reduction potential, pH, and soil texture. The research results showed that soil qualities in shrimp ponds in Tulang Bawang Regency were still in range for shrimp culture. In generally, shrimp ponds in the area have soil textute of clay, sandy, and sandy clay.Chlorophyll a content, oxidation reduction potential (ORP) and organic carbon matter content were 21,5 μg/g, 76 mv and 1,26% in average respectively.  Meanwhile  cation exchange capacity and soil pH were 11,2 me/100g and 6,8 in average.

Abstract

L. hemprichii is one of the marine ecosystems with high biodiversity and the most productive. The more healthy corals, the higher productivity in the sea. The existence of light is needed for L. hemprichii for its growth. Moreover L. hemprichii has color that produced by symbiotic algae pigments such as carotenoid pigments. Carotenoid pigment has active role to absorb light in process of photosynthetic of algae symbionts. The aims of this study were to gain different effects of  light intensity to color gradation of red and carotenoids content of L. hemprichii. The study was conducted by placing L. hemprichii into aquriums with ICR treatment (Low Light Intensity = 1514 Lux), ICS treatment (Medium Light Intensity = 3028 Lux), treatment ICR (High Light Intensity = 4547 Lux). The results showed that the light intensity affect the color gradation of  coral L. hemprichii and light intensity affect the concentration of total carotenoid pigment L. hempirchii. The best light intensity for L. hempirchii color and carotenoid pigment production was high light intensity (4547 Lux).

Abstract

GIMacro II prawn larvae is able to grow well at a salinity of 8-15 ppt. This condition can be improved by improving the methods of adaptation to changes in salinity prawn larvae production activities, by determining the pattern of changes in salinity are right. Salinity media through osmotic pressure affect the physiological activity, where the cells in body organs prawns should be in liquid media with ionic composition and concentration of the same with the environment. Having obtained the optimum salinity on larval rearing prawns GIMacro II in different salinity media is expected to produce a population of prawns GIMacro II with superior durability specific to environmental conditions, which can then be directed to improve the utilization of marine resources to the salinity of the best. This research aims were to study the growth and survival of larvae prawns GIMacro II reared on media of different salinities. The study used completely randomized design with three treatments and three replications. The treatments were larval rearing prawns GIMacro II at different salinities (10 ppt, 12 ppt, and 14 ppt). The results showed that the culture of prawn larvae GIMacro II at different salinity affect significantly on growth and survival of larvae prawns GIMacro II.  The highest development of GIMacro II prawn larvae obtained from 12 ppt salinity treatment (7.13 ± 0.03%) and the highest survival rate was obtained also from 12 ppt salinity treatment (67.67 ± 4.51%)
