Abstract
<pre><em>The sea water is a component that interacts with the terrestrial environment, where sewage from the land will lead to the sea. Waste containing these pollutants will enter into coastal waters and marine ecosystems. Partially soluble in water, partially sinks to the bottom and was concentrated sediment, and partly into the body tissues of marine organisms. This study was conducted to determine the level of pollution of sea water on the coast in the district of Tuban. This research was conducted in the Coastal Water Tuban, East Java. The main material used in research on Analysis of Water Pollution in Coastal Sea on Tuban. The method used in this research is using storet method and compared to the quality standards of the Environment Decree No. 51 in 2004. Based on the analysis of testing at five sampling point’s seawater around Bodies Tuban, obtained by sea water quality measurement results either in physics, chemistry, and microbiology varied. The level of pollution of sea water around Coastal Tuban obtained by using Storet Method average value of analysis is -4.2 included in class B are lightly blackened, while using values obtained Pollution Index average pollution index of 3.60 is included in the category lightly blackened.</em></pre><p><em> </em></p><pre><strong>Keywords:</strong> <em>Analysis of the pollution level of seawater on the coast in Tuban, Quality Standards of Sea Water, Storet Method.</em></pre><pre><em><br /></em></pre>
Highlights
The territorial waters of the coastal one highly productive ecosystems in marine waters
Development usually mainly concentrated in coastal areas, so that often creates a negative impact on the potential of these resources, human activity in exploiting natural resources on it, such as industry, agriculture, fisheries, mining, navigation, and tourism are often multiple overlap, so it is not uncommon benefit or value to the ecosystem will be down
The research is, data analysis of the quality of sea water around Coastal Tuban will be compared with the quality standards of the Environment Decree No 51 of 2004 on marine water quality standard for marine biotas
Summary
The territorial waters of the coastal one highly productive ecosystems in marine waters. Development usually mainly concentrated in coastal areas, so that often creates a negative impact on the potential of these resources, human activity in exploiting natural resources on it, such as industry, agriculture, fisheries, mining, navigation, and tourism are often multiple overlap, so it is not uncommon benefit or value to the ecosystem will be down. These activities often produce waste pollutants harmful to the marine waters life of or destroy fishes habitat in coastal areas. Based on Law No 23, 1997 (Anonymous, 2006), pollution is the entry or the entry living creatures, substances, energy or other components into the environment with human activities so that quality decreases to a certain level which causes the environment not to work as intended
