Cu that is absorbed in marine sediments can accumulate in the food chain even in small concentrations. Cu analysis in these sediments can be used to analyze water pollution due to human activities. The purpose of this study was to determine the level of Cu in decomposed sediments with variation of solvent concentration, variation of decomposition time, and variation of solvent volume and then compare the result of Cu analysis decomposed using HNO3 solvent under effective condition with aqua regia solvent. The method of analysis used is decomposition technique of sediment sample by using reflux and then analyzed with AAS.. Cu yang terserap dalam sedimen laut dapat berakumulasi dalam rantai makanan meskipun dalam konsentrasi kecil. Analisis Cu dalam sedimen ini dapat digunakan untuk menganalisis pencemaran perairan akibat aktivitas manusia. Tujuan penelitian ini adalah menentukan kadar Cu dalam sedimen yang didekomposisi dengan variasi konsentrasi pelarut, variasi waktu dekomposisi, dan variasi volume pelarut dan membandingkan hasil analisis Cu yang didekomposisi menggunakan pelarut HNO3 pada kondisi efektif dengan pelarut akuaregia. Metode analisis yang digunakan yaitu teknik dekomposisi sampel sedimen dengan menggunakan refluks dan dianalisis dengan SSA.

Coral reefs are one of the typical ecosystems in coastal areas that have ecological and economicvalue. There are many cases of coral reef damage in Salah Nama Island caused by natural andhuman factors. Coral reefs damage is mostly caused by human activities such as water pollution,destructive fishing and using of ship anchors. Activity of devotion society aims to provideinformation and skills to fishermen groups in Salah Nama Island about coral transplantationtechniques, as well as conducting coral transplantation activities as one of the efforts to preservethe ecosystem of coral reefs. Based on the description of the problems and objectives of devotionsociety, the activities that have been done are counseling to the partner fishermen abouttransplantation and coral benefits in ecosystem, transplantation practice and coral transplantationmonitoring.

Renewable Natural Resources

Indonesia is a very large and wide country, consisting of many islands and abundant natural resources. Natural resources in Indonesia are everything that comes from nature that is used to meet the needs of human life. Generally, natural resources in Indonesia can be classified based on their nature, namely renewable natural resources and non-renewable natural resources. Humans are very dependent on natural resources and the sustainability of natural resources is strongly influenced by human activities. Watershed is one of the natural resources that is very complex and consists of various components that make it up. The functions and benefits of water resources themselves, including rivers, require various efforts to improve and protect water so that it is efficient and effective for living things and the surrounding environment. One of them is the Bindu river in the Kesiman Traditional Village. The Bindu River is widely used by the community, causing water pollution in the Bindu river, such as the Kesiman Traditional Village which has an important role in suppressing the occurrence of water pollution that occurs in the Bindu river.   Negara Indonesia merupakan negara yang sangat besar dan luas, terdiri dari banyak pulau dan sumber daya alam yang melimpah. Sumber daya alam di Indonesia merupakan segala sesuatu yang berasal dari alam yang digunakan untuk memenuhi kebutuhan hidup manusia. Umumnya sumber daya alam di Indonesia dapat digolongkan berdasarkan sifatnya yaitu sumber daya alam yang dapat diperbaharui dan sumber daya alam yang tidak dapat diperbaharui. Manusia sangat bergantung pada sumber daya alam dan kelestarian sumber daya alam sangat dipengaruhi oleh aktivitas manusia. Daerah aliran sungai merupakan salah satu sumber daya alam yang sangat kompleks dan terdiri dari berbagai komponen yang menyusunnya. Fungsi dan manfaat sumber daya air sendiri termasuk sungai memerlukan berbagai upaya untuk peningkatan dan perlindungan air agar berdaya guna dan berhasil guna bagi makhluk hidup dan lingkungan sekitar. Salah satunya adalah sungai Bindu yang berada di Desa Adat Kesiman. Sungai Bindu banyak dimanfaatkan oleh masyarakat sehingga menyebabkan terjadinya pencemaran air di sungai Bindu, seperti Desa Adat Kesiman memiliki peranan penting dalam menekan terjadinya pencemaran air yang terjadi di sungai Bindu.

The Common

Ethics is a branch of philosophy that analyzes right or wrong of an action.  Ethics studies all aspect of human activities; which water pollution is one.  Water pollution is the emission of waste or chemicals into water bodies at a quantity that is harmful to man and the aquatic organisms.  The Effects of water pollution include mass extinction species, decrease in the biodiversity, and scarcity of fresh water. The question to ask is “how can   water pollution be ameliorated if not totally eradicated?” Using the method of philosophical analysis, the paper suggests that the implementation of deep ecological principles by policy makers would be abatements and environmental consciousness for the common good of the society.

<p>The article presents the current distribution of arsenic in agricultural soils of Slovakia. The current concentration of arsenic (extracted with <em>aqua regia</em>) was measured and evaluated based on 318 monitoring sites of national soil monitoring system in Slovakia. Based on the obtained results, one can state that the average content of arsenic is lower than the valid hygienic limit for arsenic (25 mg.kg-1) for predominated sandy-loamy and loamy soils in Slovakia. Increased values of arsenic were determined only for the Horná – Upper Nitra region (anthropogenic impact) – 24.5 mg.kg-1 and for the Stredný – Central Spiš region (mixed anthrophogenic and geogenic impact) – 129.5 mg.kg-1. These regions belong to the most arsenic-affected regions in Slovakia, where the content of bioavailable forms of arsenic is also increased in the range of 0.013–0.997 mg.kg-1. The hygienic limit for bioavailable arsenic in soils of Slovakia is 0.4 mg.kg-1. Finally, there is a serious risk of arsenic transport from soil into the plants and food chain especially in case of acid soils. A higher risk of As presence seems to be in anthropogenically affected soils.</p>

The Subject

Water is one of the most essential needs for life. About 0.3% of the water resources in the world are usable. Water shortages already exist in many regions, with more than one billion people without adequate drinking water. This situation is one of the most important indicators of why we should be very sensitive and conscious towards our water resources.As the world population increases need water also increases.However, as a result of different effects and especially human activities, water resources are decreasing, polluted and still used unconsciously.Water use has doubled increased between the years 1940-1980 and is faced with the danger of water shortages in many countries such as Turkey.Therefore, it is necessary to take and implement measures as soon as possible and we have to use water resources carefully. The aim of this study is to review the literature on the subject, to better understand the importance of water and to evaluate the issues such as preventing water pollution and waste from a theoretical perspective.

Weather Anomalies

Environmental damage is a serious problem at this time. Environmental damage is caused by human activities themselves. We have felt the impact of environmental damage at this time. Weather anomalies, air, land and water pollution have become part of our daily lives. Environmental damage must be repaired immediately, because this concerns the sustainability of human life. Knowing the main causes of environmental damage is a must before repairing the damage. modernism turned out to be the main cause of environmental damage. Modernism is disastrous for human life because it separates between science and religion. In fact, religion, especially Islam, teaches people to always preserve the environment. Therefore, returning to the teachings of Islam is a solution to overcome environmental damage.
