Abstract

Vannamei shrimp (Litopenaeus vannamei) is one of the commodities that is a priority in aquaculturedevelopment activities in Indonesia. The success of vannamei shrimp culture is influenced by variousfactors such as fry quality, feed quality, land carrying capacity, application of biosecurity and goodwater quality management. Water quality is closely related to the phytoplankton community containedin a waters. This study aims to analyze the abundance and dominance of plankton species found inpond waters. Monitoring the abundance of phytoplankton was carried out in 4 plots of vannameishrimp aquaculture ponds at the Brackish Water Aquaculture Fisheries Center (BBPBAP) Jepara,namely plots A51, A51, A61 and A62. Identification and calculation of phytoplankton cells werecarried out using a haemocytometer and Sedgwick. The results of the analysis showed that the highestabundance of phytoplankton was found in plots A61 at week 9 with a cell number of 36.73 x 106cells/L, while plots A51, A52 and A62 decreased. Overall plot A62 had better water quality conditionswhen compared to plots A51, A52 and A61 indicated by the phytoplankton abundance value of 34.63x 106 cells/L at week 9 and the dominance index of green algae, namely D > 0.5.

Abstract

Indonesia has a lot of potential in natural resources, one of which is seaweed. Seaweed is one of the natural ingredients that contain water-soluble dietary fiber. The fiber content in seaweed can be categorized as a functional food. The fiber content in seaweed varies, from 36-60% dry weight, 55-70% of the former percentage is soluble fiber consisting of alginate and carrageenan with varying amounts depending on the type of seaweed and environmental conditions. The dietary fibers are useful for disease prevention and health maintenance. Dietary fiber can prevent several diseases, including coronary heart disease (cardiovascular). The effect of dietary fiber according to Liu et al (2002) is a very high fiber diet (55 g/1,000 kcal) which resulted in a 33% reduction in LDL cholesterol (Low-Density Lipoprotein) in two weeks period. The mechanism of dietary fiber reduces cardiovascular disease since it is able to bind bile acids (the end product of cholesterol), thereby preventing its reabsorption from the intestine. Cholesterol that is bound to bile acids and lignin/pectin cannot be absorbed by the intestines but will be excreted in the feces.

Abstract

Indonesia has great potential in the development of the fisheries sub-sector consisting of capture fisheries and aquaculture. Shrimp is Indonesia's main export commodity in the fisheries sector. One type of shrimp, namely, vannamei shrimp. Vannamei shrimp have the characteristics of being able to live in the salinity range of 5-45 ppt with optimal salinity of 10-30 ppt; temperature range of 24° - 32°C with an optimal temperature of 28° - 30°C; The protein requirement is low, namely 32% with an FCR of 1.5 and the percentage of meat is 66 – 68%, higher than tiger prawns which is only 62%. The principle of freezing shrimp is one way to slow down the process of quality degradation, either by autolysis, bacteriology, and oxidation. This research is an experimental study that consists of the main parameters, namely the value of protein content, Total Volatile Base, and supporting parameters of organoleptic test values (color, aroma, texture) in vannamei shrimp with differences in temperature and shelf life. Consisting of independent variables, namely shelf life and temperature, dependent variables, namely protein, organoleptic, and TVB, as well as control variables of vannamei shrimp size 100 with an age of 2 months, and storage media. A completely Randomized Design (CRD) was used as the experimental design. Data were analyzed using Analysis of Variance (ANOVA) and continued with Duncan Multiple Range Test (DMRT). The results showed that the effect of shelf life and differences in freezing temperature of vaname shrimp, on protein and TVB levels of white vaname shrimp had met the quality requirements so that it was suitable for consumption and obtained the highest average value for each parameter of texture, color, and odor, namely 7 in the shrimp freezing treatment for 1 day at a temperature of -5°C.

Abstract

The development of seawater cultivation (marineculture) leads to important economic commodities, one of which is shellfish such as abalone shells (Haliotis squamata). Abalone is very popular among people both domestically and abroad, this has caused the demand for abalone to increase. However, most of the abalones are obtained from wild catches. This is what causes the abalone population in nature to decline. Therefore, abalone cultivation, especially seeding, is one way to meet market demand. Problems arise when the larvaes are in the larvae phase, which is susceptible to pest attacks and disease and feed that is appropriate to the size of the abalone larvaes. This research is descriptive research where the primary data collection method is carried out in 3 ways, namely observation, active participation and interviews. This activity aims to find out pests and diseases that attack abalone larvaes and the type of feed that suits the size of the abalone larvaes.

Abstract

Dunaliella salina is one of the microalgae that has the potential to be utilized because it has a fairly high nutritional content as much as 57% protein, 32% carbohydrate, 6% lipid, and 5% chlorophyll pigment. Chlorophyll produced by microalgae is inseparable from salinity and nitrogen because when microalgae carry out photosynthetic activities, microalgae need nitrogen as a nutrient for building material for the chlorophyll-a pigment network. This study aims to determine the effect and best concentration of nitrogen and salinity on the chlorophyll-a content of D. salina microalgae. The method used was a factorial design (FD), namely salinity 25ppt, 30ppt, 35ppt, and 40ppt and nitrogen concentrations in modified walne media, namely 100%, 75%, 50%, 25%. Data analysis in this study used the Anava Test and continued with the Duncan Test. The data obtained were analyzed by Anava Test followed by Duncan's Test showing significant results. The highest chlorophyll-a content was at 35 ppt nitrogen 50% salinity with 8,268 mg/mL chlorophyll-a content and the lowest chlorophyll-a content at 40 ppt nitrogen 25% salinity treatment was 2,351 mg/mL. At a nitrogen concentration of 50% there was an increase in the chlorophyll-a content, while the nitrogen concentration of 100% and 75% of microalgae decreased the content of chlorophyll-a. At a nitrogen concentration of 25%, there was no increase in the chlorophyll-a content because under conditions of nitrogendeficiency, the formation of chlorophyll would decrease, causing the process of photosynthesis to be hampered. Based on the research, it can be concluded that differences in nitrogen concentration and salinity can affect the chlorophyll-a content ofD. salina.
