Abstract

  Marine pollution results in a decrease in the quality and quantity of coastal and marine resources. Most of the people in tambak sub-district have a livelihood as fishermen and work in the field of fish processing industry and seafood trade and the location of the waters are often passed by industrial vessels. This resulted in increased ship activity in the waters of Labuhan Beach, Tambak District, Tanjungori Village. As the activity increases it causes marine pollution. One of the sources of pollution produced is oil spills from former fuel boats or ships that cross the area of the water. This method can provide information about the condition of the waters according to their designation. The purpose of this study is to know the water quality based on the parameters of temperature, pH, salinity and brightness and know how much oil content in the waters of Labuhan Beach, Bawean Island. Sea water sampling was conducted at 4 stations, then the results were compared with sea water quality standards for biota based on KEPMEN LH No.51 Year 2004. The results showed that the oil content ranged from 0.0016%–0.0377%. As for the pH parameter, salinity and brightness in accordance with the quality standard, for the temperature parameter exceeds the standard value of quality. Based on this study, pollution index calculations show that the waters of Labuhan Beach, Bawean Island are in the category of lightly polluted.

Abstract

Coastal area is defined as a transitional area between land ecosystems and marine ecosystems. Coastal areas are very vulnerable to environmental pressures, both on land and at sea. One form of pressure that threatens the sustainability of coastal areas almost all over the world is the phenomenon of sea level rise. The phenomenon of sea level rise itself is a result of the expansion and contribution of ice due to increased of melting ice as a result of global warming. It is predicted that in 2100 there will be a rise of sea level that reach 0.26 to 0.98 meters. Sea level rise can be analyzed using a trendline based on monthly slopes to determine the average of sea level rise per year. In addition, to determine the vulnerability of coastal areas to sea level rise, it can be determined through two aspects: aspects of geophysical vulnerability and aspects of socio-economic vulnerability.

Abstract

Coral disease is a disturbance to coral health that causes physiological disturbances for coral biota. The emergence of coral disease is characterized by discoloration, damage to skeleton coral biota, to the loss of its tissueThis study aims to identify the type of coral disease and determine its prevalence in Kaledupa Waters, Wakatobi National Park, Southeast Sulawesi. This research was conducted in June 2021 in the Kaledupa Waters of Wakatobi National Park using the Belt Transect method with a size of 3 x 50 m at 3 observation points at a depth of 3-5 meters. Measurement of Oceanographic Physics-Chemistry parameters is carried out directly in the field. Identification of coral diseases was carried out descriptively based on the coral disease handbook and journal references. The results obtained found 4 types of coral disease that infect coral biota in the waters of Kaledupa Island, Wakatobi National Park, namely Black Band Disease (BBD), White Band Disease (WBD), White Pox and Ulcerative White Spot (UWS). As well as the results obtained for the overall prevalence of coral disease in the study site an average of 1.5%.

Abstract

The accumulation of biofouling on a substrate causes material loss and huge economics in the maintenance of aquaculture systems, ship hulls, seawater pipelines, coastal power plants, and other marine infrastructure. Prevention of the attachment of biofouling organisms using antifouling paints that have been developed and used for a long time. Antifouling paint contains chemical compounds (biocides). The most sensitive organisms to antifouling paint are gastropods and bivalve that cause endocrine disorders, larval disorders and shell malformations. This study aims to obtain antifouling bacteria through the isolation process of bacteria obtained from the bark Avicennia marina mangrove. The method was beginning with isolation of bacteria bark of Avicennia marina mangrove, identification of bacteria, and antifouling activity test. The results obtained from isolation of bacteria, there are 9 bacteria endophytic symbionts of the inner bark and 9 epiphytic bacteria of the outer bark. The inhibition zone test of the endophytic bacteria in the bark showed that there was no antifouling activity.

Abstract

The waters of Sedayu Lawas Lamongan are widely used as salt production sites. Salt production is strongly influenced by the quality of raw water used. The quality of water raw materials must be free from heavy metal pollutants or in accordance with the threshold value (NAB). One of the heavy metals that pollute the environment is Lead (Pb). This study aims to analyze the heavy metal content of Pb in water raw materials, how the quality of raw materials of water when compared with quality standards and how the correlation between water physics-chemical parameters include rainfall, wind, temperature, salinity, pH to Pb content in 5 stations observation. The heavy metal content of Pb was analyzed by the Inductively Coupled Plasma-Optical Emission Spectrophotometer (ICP-EOS) method. Correlation using Pearson method. The results showed that Pb content of raw water for salt production in five stations was 0.0626, 0.0672, 0.0455, 0.0487, and 0.0416 ppm, respectively. Based on the measurement results when compared with the Ministerial Decree No. 51 Year 2004, the raw material of water used exceeds NAB which is 0.008 ppm. The result of parameter correlation to Pb content shows salinity, pH, has a strong inversely relationship affecting the presence of heavy metals. The temperature parameter has a direct relationship to the Pb content
