"The purpose of this study is to clarify the ecosystem quality of Bayur Bay based on heavy metallic elements in surface sediment. Samples were collected using grab sampler from four stations in Bayur Bay. Concentration of heavy metallic elements were determined using ASS. Results of linier regression analysis show negative correlation between Cd concentration and mean size diameter. COntrastingly, Pb has correlation with size diameter. Cd and Pb concentrations in surface sediment of Bauyr Bay are lower than the ERL and ERM indicating it is not yet polluted."

"We use more than 100 000 chemicals in our daily lives to promote health, treat disease, facilitate transportation, use in industrial processes, grow food and access clean water. While these developments have improved human lives, many of these compounds ultimately end up in our seas and oceans where they represent a threat to marine life, ourselves and our continued use of the oceans to treat our waste, provide us with food and offer us recreation. Many of the pollution problems of previous decades seem to have been resolved, in the developed world, or at least managed to minimise their environmental impacts. However, despite treatments being available that reduce their damaging qualities, a potent mixture of toxic compounds enter the marine environment every day along with other potentially harmful additions including heat, noise and light and non-native species. The question thus arises: is pollution a problem that has really been solved? How well are we managing traditional pollutants? What are the challenges we still face today? What are the upcoming marine pollution challenges that face society? This volume describes the different marine pollutants, the science behind measuring their ecological impacts and how they are monitored in the environment, including traditional and new management approaches. This is an up-to-date account of marine pollution within the broad ecological and social context of a growing, technologically advanced, global population."

"Tumpahan minyak di perairan telah menimbulkan pencemaran di lingkungan laut maupun di daerah pesisir pantai, sehingga perlu dilakukan penelusuran kejadian tumpahan minyak dapat digunakan untuk mitigasi bencana. Penelitian ini bertujuan untuk mengetahui sebaran dan pergerakan tumpahan minyak di perairan Cilacap, Jawa Tengah tahun 2008, serta hubungannya dengan angin, arus, dan pasang surut. Identifikasi tumpahan minyak dilakukan dengan interpretasi citra Modis surface reflectance dengan melihat penurunan nilai spektral dan diikuti oleh peningkatan nilai fluorescence index. Tumpahan minyak menyebar di sekitar pesisir pantai Teluk Penyu Kecamatan Cilacap Selatan, Kecamatan Cilacap Utara, Kecamatan Kesugihan dan Kecamatan Adipala, dengan luas total area yang tercemar sebesar 1.378 ha. Angin merupakan faktor dominan yang berpengaruh terhadap pergerakan minyak dibandingkan dengan arus dan pasang surut. Pergerakan tumpahan minyak menyebar menjauhi lokasi sumber tumpahan dan bergerak searah dengan arah angin menuju ke arah timur. Dari kondisi oseanografis menunjukan bahwa jenis penyebarannya termasuk kedalam jenis difusi gabungan ekspansi dan relokasi.

The oil spill in the waters has occurred pollution in the marine environment as well as in coastal areas, so needs to do investigation of occurrence oil spill which can use for disaster mitigation. This research is going to describe the distribution and movement of oil spill in Cilacap coastal, Central Java in 2008, and its relation with the wind, currents, and tides. Identification of oil spill conducted by Modis image surface reflectance interpretation by looking at the impairment of spectral and was followed increase in fluorescence index value. Distribution of oil spill spreading around at Teluk Penyu coast of south Cilacap, North Cilacap, Kesugihan, and Adipala, with a total area of 1.378 ha contaminated. Wind is the dominant factor influencing the movement of oil compared with currents and tides. The movement away from the spreading oil spill and the spill source location moves in the direction of the wind toward the east. Of oceanographic conditions indicate that the type of distribution, including the type of diffusion into the combined expansion and relocation."
