Abstract

Water is the most important requirement for all organisms, either to humans, plants, animals, and microorganisms. It was caused water function in the growth and survival organisms. Aquaculture is an activity to maintain, raise, and/or breeding fish and harvest their products in a controlled environment. Cultivation was done in a sustainable manner for the benefit.Pollution in water can be caused death of fish is heavy metal cadmium (Cd) pollution. Processing of heavy metal contaminated water is the most simple and low cost is a biological treatment with kariba weed (Salvinia molesta). But the effect of kariba weed to the decline of heavy metal cadmium is not significantly reduced, so that needs to be combined with the zeolite so that the heavy metal cadmium decline more significantly. This reseacrh to determine the effect of the combination kariba weed (Salvinia molesta) and zeolite to the decline of the heavy metal cadmium (Cd). This reseacrh uses a completely randomized design (CRD) with four treatments performed five repetitions, treatment A using 0 g kariba weed and 150 g of zeolite, Treatment B using 50 g kariba weed and 100 g of zeolite, Treatment C using 100 g kariba weed and 50 g of zeolite and treatment D using 150 g kariba weed and 0 g zeolite. The result on this research analize by  ANOVA statistical test (Analisis  of  Variance) to know there was the different between treatments, afterwards, continued by space doubled test Duncan. The result showed combination kariba weed (Salvinia molesta) and zeolite significant effect on decreasing the concentration of heavy metal cadmium (Cd) (F count > F Tabel 0.05). It is evident in this research, and only had one week treated water cadmium (Cd) of 1 ppm concentrations is fall. The averages treatment on decreasing concentration heavy metal cadmium (Cd) was treatment A 98,7%, tretment B 97,1%, treatment C 97,2 % and treatment D 95,8%.

Abstract

The presence of plankton in pond ecosystems fluctuates. Phytoplankton needs nutrients to support their growth. The higher the nutrient content in the waters, the greater the abundance of phytoplankton. The increased abundance of phytoplankton will stimulate the growth of zooplankton. One of the causes of changes in ecosystems in waters is caused by water waste that comes from the rest of the feed and feces and in the form of ammonia or nitrite and nitrate. Water quality is a critical factor in the cultivation process. As a preventative measure, the decrease in water quality in waters is by giving probiotic bacteria. This study aims to obtain information about the effect of giving different commercial probiotics to the diversity and density of seawater plankton in the experimental bath. The method used in this research is descriptive method with a Completely Randomized Design (CRD) as an experimental design. The treatments used are different types of commercial probiotics, with as many as six replications. The main parameters observed were the diversity and density of seawater plankton in the experimental media. Supporting parameters observed were temperature, pH, dissolved oxygen, salinity, ammonia, and C / N and N / P ratio of water. Commercial probiotics are given every 7 days at a dose of 2 mg / l. The results showed that the treatment of different commercial probiotics resulted in differences in diversity, density and plankton dominance. The highest diversity index value (H ') obtained in probiotics A was 6.85 (moderate diversity), and dominance (C) was 0.96, meaning that there was dominant plankton, Chlorella sp. and Oscillatoria sp. whereas the highest plankton density was obtained in probiotics B at week 1 of 5.98x106 ind / ml.

Abstract

Kappaphycus alvarezii is one of Indonesia's export commodities because it has high economic value as food and industry. One area in East Java which is the center of seaweed cultivation is Sumenep regency such as Saronggi and Bluto. Currently Sumenep Regency is an area for oil and gas exploration and exploitation. Types of pollutants resulting from these activities cause pollution in aquatic environments such as lead (Pb), mercury (Hg) and cadmium (Cd). The heavy metals found in the waters can be absorbed and accumulated in the seaweed thallus. The purpose of this research is to know the heavy metal content of Pb, Hg, Cd, chlorophyll-a, and cell morphology in E. cottonii in Bluto and Saronggi waters. This research is survey and descriptive research. The results showed that there are differences in heavy metal content of lead in E. cottonii, seawater, and sediments in Bluto waters and Saronggi waters. The waters of Bluto have a lower amount of chlorophyll-a than the Saronggi Waters. Cell wall thickness in E. cottonii in Saronggi Waters has thinner cell walls than Bluto waters. Measurement of water quality in Bluto and Saronggi waters through temperature, pH, salinity, brightness and DO parameters.

Abstract

Catfish (Pangasius sp.) As a source of animal protein. Fish catfish have a thick white meat so that it can be processed into a wide range of diversified products. The process of fried fish cake can result in fat or autooxidation process. Autooxidation can be inhibited by the presence of antioxidant compounds. One source of natural antioxidants are bay leaf Eugenia polyantha.This research was carried out by experimental methods and the use of experimental design of randomized Complete Design (RAL). RAL is used when the material and condition of the experiment are homogeneous. This research consists of four concentrations of extract treatment bay leaf, namely 0%, 10%, 20%, 30%. Fish cake has been fried done soaking for 30 minutes. Water content showed no significant difference (p> 0.05) at 24 hours to 28, this indicated that the addition of bay leaf extract did not affect the moisture content during storage. The high water content at 0 hour is caused by the process of soaking the fish cake  in the extract solution. The highest value is shown by the concentration of 30% at the hour to 0 that is 52.78%, this indicates that the fish cake by soaking can meet the quality score SNI 7757:2013 which is a maximum of 60%. The fat content in the fish cake continues to decrease, indicating the occurrence of oxidation during storage. Levels of TBA in fish cake continue to increase that can be slowed by the extract of bay leaves with a concentration of 30%.
