Abstract

The condition of coral reefs in Damas Beach is included in the bad category because there are many fragments of coral reefs (rubble) caused by fishing nets caught in the reef. Based on the problem of coral reefs contained in the waters of Damas Beach, there are innovations to sink artificial reefs. The condition of artificial reefs that have been derived in the waters of Damas Beach within 2.5 years needs to be monitored to find out the macroinvertebrates that stick to the artificial reefs. Retrieval of macroinvertebrate data using the underwater photo transect method with the help of underwater cameras to produce observational data. The results found 10 types of macroinvertebrates with a total of 9,293 individuals. The composition of attached macroinvertebrates is dominated by barnacles by 66% and the density of macroinvertebrates is dominated by barnacles by 4.50 ind / m² out of a total density of 6.88 ind / m².

Abstract

Heavy metal Cu is an essential heavy metal that is a heavy metal needed to stimulate the activity of enzymes during metabolism. Cu metal has a tendency to be toxic as long as its presence has exceeded the threshold value. The metal-contaminated water environment has the potential to affect the surrounding environment. The purpose of this study was to determine the effectiveness of Cu heavy metal reduction by using a combination of seaweed biofilter (Gracillaria sp.), Blood shells (Anadara granosa), and zeolites. This study uses a combination of biofilter between seaweed (Gracillaria sp.) And blood shells (Anadara granosa) with different concentrations in each treatment. The results showed the use of the right biofilter combination can reduce levels of heavy metals Cu. The initial content of heavy metal Cu is 1 mg / L to 0.119 mg / L, the best combination composition on P4.

Abstract

Indonesia is known as one of the world's marine biodiversity centers with its rich coral reefs. Coral growth depends on environmental conditions, which in reality do not always remain due to disruptions originating from nature or human activities. The growth of coral reefs in a sea water is strongly influenced by the quality of its waters such as chemical oceanographic factors namely salinity, pH, DO, nitrate and phosphate. The data collection was carried out twice in September and November 2019 in Damas Waters, Trenggalek, East Java. The waters of Damas Beach are located in Karanggandu Village, Watulimo District. The purpose of this study was to determine the condition of coral reefs in Damas Waters, to determine the effect of water quality on artificial reefs in chemistry in Damas Waters and to determine the relationship of quality parameters of chemical waters with artificial coral reefs in Damas Waters, Trenggalek, East Java. The sampling method is done by purposive random sampling that is determining the sample with certain considerations. The location points used by 20 stations are spread, namely on artificial reefs, natural coral reefs, open seas and the area around the harbor. Measurements made include in situ water quality with a multiparameter measurement tool, namely AAQ. The results obtained that in all stations found good water conditions for the life of coral reefs, and also the analysis of the relationship of each parameter and coral reefs influence each other.

Abstract

The availability of plankton in the waters is influenced by nutrient content, and the waters physics-chemical conditions. The higher the nutrient content in a waters, the higher phytoplankton abundance in the waters will be.This research is conducted at faculty of fisheries and marine education pond Airlangga University. It is aimed to density dynamics and plankton diversity in pond with different bases. This research method uses survey method.The reseach results shows that the highest density in tarpaulin pond is located at point four on the first day that reaches 1,822,000 ind/l, The highest total density on the ground pools is got on first day on the first point of 245,000 ind/l.

Abstract

Increasingly rapid industrial development poses serious environmental problems such as wastewater.The higher the number of production, the more waste that wasted and can decrease the environment quality. Fieldwork practice activity is carried out starting from the date of January 20, 2014, until February 15, 2014. The purpose of this fieldwork practice is to acquire knowledge and skills on the field of wastewater treatment technique and to know the parameters of the wastewater inlet and outlet channels in comparison with wastewater quality standards. The method that used in Field Work Practice This is descriptive, the method to describe the circumstances or events in a particular region. The result obtained from fieldwork practice known that wastewater treatment techniques consist of preliminary treatment activities, primary treatment, secondary treatment, sedimentation, and disinfection. Preliminary treatment activities is a filtering process substantial in the wastewater that comes out of the inlet channel using four mesh size of the net. The primary treatment for separating solids that escaped from the screening process and disposed to wastewater reservoirs. Secondary treatment activity including Aerobacter sp., Nitrosomonas sp., Nitrobacter sp., Bacillus sp. of bacteria and oxygen addition inside of wastewater. Sedimentation phase separation process is carried out suspended solids in wastewater using clarifier pond. Disinfection stage which activities the addition of chlorine with 222 ppm of doses to kill harmful pathogens. The final stage test to determine the parameters of wastewater effluent quality by using living fishes and taking the sample from another institution.
