BAB I PRELIMINARY A. writing background In the current era environmental pollution is a serious problem faced by the community. Without them knowing it, their daily activities can pollute the environment so that the environment becomes shabby and unhealthy so that it can cause the emergence of sources of disease. If it is not prevented effectively then what is feared is that the place becomes unfit to be occupied. Based on the Basic Law on Environmental Management, the definition of environmental pollution is the entry or inclusion of living things, hazardous substances or other components that are destructive or harmful to an environment, but also can be interpreted as changes in an environmental order that occurs due to human activities or natural processes so that the quality of the environment decreases at a certain level and causes the environment to become unable to function properly. From this increasingly rampant environmental problem, the most basic thing is to be able to give awareness to yourself to be more sensitive to the environment. To increase knowledge about this, of course, supporting media is needed, such as books. Therefore on this occasion, the author will provide a review of two books relating to environmental pollution. B. formulation of the problem From the explanation of the background above, the formulation of the problem of this writing is: 1. What is meant by Environmental Pollution and the cause? 2. What books are appropriate for the problem of Environmental Pollution? 3. Strengths and Weaknesses of each book

C. Writing purpose The purpose of this paper is: 1. Can find out information about Environmental Pollution 2. Can find suitable books as a reference in environmental pollution problems 3. Can know the advantages and disadvantages of each book.

A. Book Summary Book I Water pollution is a change in conditions in a water reservoir such as lakes, rivers, oceans and ground water due to human activities. Lakes, rivers, oceans and ground water are important parts of the human life cycle and are part of the hydrological cycle. In addition to also drain the water drain sediment and pollutants. Its various functions greatly help human life. The biggest use of lakes, rivers, oceans and ground water is for agricultural irrigation, raw water for drinking water, as a drainage channel for rainwater and wastewater, in fact it has the potential as a tourist attraction. Although natural phenomena such as volcanoes, storms, earthquakes etc. also result in major changes to water quality, this is not considered as pollution. Water pollution problem,Water pollution is a major global problem that requires evaluation and revision of water resources policies at all levels (from the international level to private water sources and wells). It has been said that water pousi is the world's leading cause of death and disease, and is recorded for the deaths of more than 14,000 people every day. An estimated 700 million Indians do not have access to toilets, and 1,000 Indian children die from diarrhea every day. About 90% of Chinese cities suffer from certain levels of water pollution, and nearly 500 million people do not have access to safe drinking water. In addition to water pollution is an acute problem in developing countries, industrialized / advanced countries are still struggling with pollution problems as well. In the most recent national report on water quality in the United States, 45 percent of river miles were assessed, 47 percent of lake acres were assessed, and 32 percent of rated bays and square mile estuaries were classified as polluted. Water is usually called polluted when it is disturbed by anthropogenic contaminants and when it cannot support human life, such as drinking water, and / or experiences a marked shift in its ability to support biotic constituent communities, such as fish. Natural phenomena such as volcanoes, algae blooms, storms and earthquakes also cause major changes in water quality and ecological status of water.

Cause : 1. Water pollution can be caused by various things and has different characteristics. 2. Increased nutrient content can lead to eutrophication. 3. Organic waste such as sewage causes an increase in oxygen demand in the water that receives it which leads to reduced oxygen which can have a severe impact on the entire ecosystem. 4. The industry removes various kinds of pollutants into their wastewater such as heavy metals, organic toxins, oils, nutrients and solids. The wastewater has thermal effects, especially those released by power plants, which can also reduce oxygen in water. 5. Like factory waste that flows into a river, like in the Citarum river, water pollution by garbage 6. Use of explosives to catch fish Consequences : 1. Can cause flooding 2. Erosion 3. Lack of water resources 4. Can make a source of disease 5. Landslides 6. Can damage river ecosystems 7. Losses for Fishermen Community steps in tackling water pollution 1. Be aware of the continuity of water availability by not damaging or exploiting springs so that they are not polluted. 2. Don't throw garbage into the river. 3. Reducing the intensity of household waste. 4. Filtering factory waste so that the waste that will unite with river water is not a bad waste of ecosystem damage. 5. Making proper and clean sanitation so that other sources of clean water are not polluted.

Several ways to deal with water pollution 1. Pollution Control and Environmental Destruction Program a) Reducing the burden of water pollution by industrial and domestic bodies. b) Reducing emissions from motorized vehicles and industry. c) Supervise B3 utilization and B3 waste disposal. d) Develop cleaner production and EPCM (Environmental Pollution Control Manager). 2. SDA Rehabilitation and Conservation Program and Environment a) Optimizing the implementation of critical land rehabilitation. b) Overcoming damage to ex-mining land, landfill, and disaster. c) Improve underground water conservation. d) Rehabilitation and conservation of biodiversity

BOOK II Chapter 5. Environmental Pollution The term water pollution or water pollution can be perceived differently by one person to another given that many reference libraries formulate the definition of the term, either in dictionaries or scientific textbooks. The definition of water pollution is also defined in the Government Regulation, as a derivative of the definition of environmental pollution defined in the law. In operational practice, environmental pollution has never been shown in its entirety, but as a pollution of environmental components, such as water pollution, sea water pollution, groundwater pollution and air pollution. Thus, the definition of water pollution refers to the definition of the environment stipulated in the Law on the environment, namely Law No. 32/2009. Indicators or signs that environmental water has been polluted are changes or observable signs that can be classified into: a). Physical observation, namely observation of water pollution based on the level of water clarity (turbidity), changes in temperature, color and changes in color, odor and taste b). Chemical observations, namely observation of water pollution based on dissolved chemicals, changes in pH 8

c). Biological observation, which is observation of water pollution based on microorganisms present in water, especially the presence or absence of pathogenic bacteria. Indicators commonly known in the examination of water pollution are the pH or concentration of hydrogen ions, dissolved oxygen (Dissolved Oxygen, DO), biochemical oxygen demand (Biochemiycal Oxygen Demand, BOD) and chemical oxygen demand (COD). Many causes of water pollution sources, but generally can be categorized into 2 (two), namely sources of direct and indirect contaminants. Direct sources include effluent coming out of industry, landfill waste, household and so on. An indirect source is contaminants that enter water bodies from the soil, ground water or the atmosphere in the form of rain. Water pollution can have a very broad impact, for example can poison drinking water, poison animal food, be a cause of imbalance of river and lake ecosystems, destruction of forests due to acid rain etc. In water bodies, rivers and lakes, nitrogen and phosphate from agricultural activities have led to the growth of aquatic plants that are out of control called eutrophication (eutrofication). The growth explosion caused oxygen to be used together by all aquatic plants, to be reduced. When the aquatic plant dies, its decomposition takes up more oxygen. As a result the fish will die and bacterial activity will decrease. The impact of water pollution is generally divided into 4 categories of KLH (in Lina, 2004), namely: a). Impact on the life of aquatic biota The amount of pollutants in wastewater will cause a decrease in the dissolved oxygen levels in the water. So that it will lead to life in water that requires disturbed oxygen and reduce its development. Besides that, death can also be caused by the presence of toxic substances which also cause damage to plants and aquatic plants. As a result of the death of bacteria, the natural water purification process that should occur in wastewater is also hampered. With wastewater it becomes difficult to decompose. Heat from the juaga industry will have an impact on the death of the organism, if the wastewater is not cooled first. b). Impact on groundwater quality Pollution of groundwater by feces commonly measured by faecal coliform has occurred on a large scale, this has been proven by a shallow well survey in Jakarta. Many studies indicate the occurrence of this pollution. c). Impact on health 9

1) The role of water as a carrier of infectious diseases varies among others: 2) Water as a medium for living pathogenic microbes 3) Water as a nest of insect spreaders 4) The amount of water available is insufficient, so that the person concerned cannot clean himself 5) Water as a medium for living vector diseases There are several diseases that fall into the category of water-borne diseases, or diseases carried by water, which are still widely found in the regions. These diseases can spread if the microbes that cause them can enter the water source used by the community to meet their daily needs. While the types of microbes that can spread through water include bacteria, protozoa and metazoa. d). Impact on environmental aesthetics With the increasing number of organic substances being discharged into the aquatic environment, the waters will be increasingly polluted which is usually characterized by a stinging smell beside the pile which can reduce environmental aesthetics. The problem of waste oil or fat can also reduce aesthetics. In addition to odor, the waste also causes the surrounding area to become slippery. While detergent or soap waste will cause a lot of foam buildup. This can also reduce aesthetics.

BAB III DISCUSSION BOOKI Excess Book In terms of the cover, the book cover is designed simply and not too much. If the topic covered is English terms, the word or sentence is italicized, making it easier for the reader to understand the book and when you see italicized words or sentences the reader will immediately know that it is English. This book helps audiences especially for people who will or have become people who are involved in geography and want to discuss environmental pollution, especially in an ecological perspective. This book is suitable to be used by students to help launch the lecture process and increase student knowledge because the material presented in this book is very detailed so this book is very suitable to be used as a source for making college assignment papers. The table of contents is neatly arranged, so the reader is easy to find the topic to be searched for. The general description presented in the book is very good. Because before discussing the material, the author made an overview of the topic. This book is easier to understand because the material discussed is not straightforward, and is discussed directly to the material. Book Weaknesses: In some discussions, there are double punctuation marks, as in the discussion the general description of the topic to be discussed includes a double dot and a direct comma after a period. There is an error in writing sentences, we can see in the general description of the material discussed this makes the readers experience confusion. There is an error in the Indonesian language rules, namely sometimes not making paragraphs in writing material. BOOK II The rapid industrial development in this era of globalization does bring many benefits to our lives but without being disrupted the industry also has an adverse impact on our environment. The word environmental pollution may have been heard by us and has become a very worrying global problem. In a book entitled "Environmental Pollution" this is discussed about the effects of chemistry on the environment and materials that can be a savior or even endanger our environment if not used carefully. 11

This book is divided into 9 (nine) chapters that discuss the influence of chemistry on the environment both land, water and air, food pollution and provide a little solution to this environmental pollution. This book also shows concrete examples of environmental pollution in Indonesia and discuss the problem. In the last chapter of this book, we also put forward the prevention of environmental pollution that we can apply in our daily lives. In this book chapter 5 discusses Water Pollution, which is explained in depth about water pollution, causes, effects or impacts that occur if pollution is continuously carried out. The advantage of this book is the elaboration of problems that are carried out simply so that they are easy to understand, a summary at the end of each chapter that can help the reader to understand the problems in the chapter, and also the language used is a language that is not ambiguous so that it can be digested properly by the reader. In this book there are also procedures for simple experiments that can. In addition to the advantages already mentioned, this book also has drawbacks where the relationship between each part is less harmonious. By reading this book, the authors hope that readers will increasingly understand the pollution problems that we are facing and also participate in preventing and preserving the environment around us Explain how disaster management and explanation of the disaster are very good. At the beginning of the explanation, this book explains how the hydrological cycle is formed, which makes the reader know the basics. At the end of each sub-section the author always makes exercises to observe the environment with questions. Each chapter describes general objectives, specific objectives, and sub topics, which make it easier for readers to understand Weaknesses: Very few formulas in the discussion are lacking in terms of listing images, tables, and charts. This book cover is less interesting. Less explain in depth how water pollution is around Indonesia.

BAB IV CLOSING

A. Conclusion Basically water pollution is indeed very detrimental to all beings and circles. Pollution means the entry of living things and certain substances or components into an environment. As a result the environmental order has changed. Pollution can reduce local environmental quality. But all of that can be overcome in various ways such as not throwing waste at the river, not throwing garbage and many more. Water pollution has become a crucial problem in Indonesia and has been rampant and most of these problems are caused by humans. Therefore to overcome this is the need for awareness of the local community on the use of water. In this report 2 books have been given as references to the problem of water pollution in which each book has advantages and disadvantages of each, but overall both are recommended.

B. Suggestion As a follow-up to the above description of water pollution, the authors propose a number of suggestions to improve sustainability in the environment around us, including: 1) There needs to be cooperation between communities in reducing the occurrence of water pollution in the environment 2) Maintain cleanliness of the living environment and the environment around the river 3) Do not dispose of garbage in waterways and rivers that can cause water pollution 4) Clean the environment so that it cannot cause disease
