Apakah itu Ozon? Ozon adalah gas yang secara alami terdapat di atmosfir, unsur kimia yang terkandung dalam partikel ozon adalah tiga buah oksigen (O3).  Sedangkan keberadaan ozon sendiri di alam terdapat di dua wilayah atmosfer. Ozon di troposfer (sekitar 10 s/d 16 km dr permukaan bumi ) sayangnya kandungan pada lapisan ini hanya 10%. Sedangkan selebihnya berada di lapisan stratosfir (50km dr puncak troposfer) disini kandungan ozon mencapai 90%. Maka seringkali disebut lapisan ozon, karena memiliki kandungan 03 (ozon) yang paling banyak. Pertanyaannya kemudian bagaimana jika lapisan ozon menipis?,   “ Menipisnya lapisan ozon menyebabkan meningkatnya radiasi ultraviolet matahari terutama UV-B yang mampu mencapai permukaan bumi”. Dari data dan pengamatan kondisi ozon di atmosfir  kondisi dari bulan Oktober 1980 sampai dengan Oktober 1991 kondisi  lubang pada lapisan ozon makin memprihatinkan dan makin membesar, hampir sebesar benua Australia. Kondisi  te...

Water is one of the primary needs of the community. The need for clean water taps supplied by the public generally. But until now, not all people get clean water from the taps so as to obtain clean water is obtained from groundwater. The use of ground water for daily needs - day for domestic use is reasonable and safe for ground water will be replenished during the rainy season. But it would be dangerous in the event of over-exploitation of ground water. Exploitation of groundwater is happening because too many people that use ground water as estates that do not subscribe to taps and industries large and small who need a lot of water every day. Worse yet, during the rainy season should be a time in which the soil absorbs water, it can not be done to the fullest. This is due to the areas that can absorb water into the ground is increasingly reduced. The rapid urban development has replaced rice fields into housing, converting vacant land into the concrete jungle of overgrown plants...

Turbidity describes the optical properties of water are determined based on the amount of light absorbed and emitted by the materials contained in the water. Turbidity is caused by the presence of organic and inorganic suspended and dissolved (eg silt and fine sand). The water has a low turbidity values ​​typically have color values ​​and the color looks the same color as the actual standard. Turbidity units as measured by the Nephelometric method is NTU (Nephelometric Turbidity Units). In accordance with the Decree MENKES NO. 907/MENKES/SK/VII/2002 levels of turbidity maximum rate is 5 NTU.Pengukuran yangdiperbolehkan turbidity in water samples by using the Nephelometric method alatturbidimeter. Principles of Nephelometric method is passed padasampel light source and intensity of light reflected by the materials causing turbidity measured using formazin polymer suspension as standard solutions. Well water samples were placed in cuvette TURBIDIMETER, then measured turbidity with a...

Water turbid water where it is said to contain so many particles of suspended material that gives the color / appearance of the muddy and dirty. The materials that cause turbidity include mud, organic ingredients that are both good and suspended particles other. Nephelometer is an instrument for measuring turbidity results in Nephelometric Turbidity Units units (NTUs). NTUs is the standard unit for measuring turbidity. In nephelometri and turbidimetri, the light source is projected through a liquid sample is stored in a transparent sample container. Generally, nephelometri using a light source that has a relatively short wavelength (eg, 500 nm-800 nm) and effectively used to detect very small particle size. Meanwhile, turbidimetri generally use a light source that has a longer wavelength (eg, 800 nm-1100 nm) and effectively used to detect particles with a larger size. If a beam of light is passed through the sample turbid, scattering intensity is reduced, and the amount of scatter...

The presence of ground water has the function of social, environmental and economic. Therefore, management should be able to ensure the preservation and availability are berkesinambungan.Peningkatan rapid exploitation of groundwater in various sectors in Indonesia have demanded the need for preparation in the form of concrete steps to address them, in particular minimize the negative impact caused. Groundwater as a water resource has now become a national issue. Groundwater which is a renewable natural resource (renewal natural resources) is now playing an important role in the provision of water supplies for a variety of purposes, thus causing a shift in the value of the groundwater itself. Groundwater in the past is the free stuff (free goods) that can be used freely without limit and do not require the use of surveillance, but in the current era of development, coupled with the increasing need for rapid groundwater has transformed the economic value of groundwater into goods (eco...

Sewage lift pump is an essential component of any wastewater treatment system. While most plumbing systems rely on gravity to carry waste material into the discharge rate for processing, wastewater lines occasionally higher than the source of the wastewater itself. In this case, sewage lift pump is used to counteract the effects of gravity and about the waste to its destination. How sewage lift pump work? Sewage lift pump, is a major component in the waste sewage lifting system, a large tank where the wastewater is collected along with the material. The tank is a floating device that increase and decrease depending on the level of waste in the tank at any given time. When the tank is filled with waste material and float up to a certain point in it, sewage lift pump will be active. Lift pump wastewater will flow upwards towards the material along the pipe empties into drains (sewers) or septic line where it will continue to be processed. Since the lift pump to move more material ...

A. Understanding the Environment Of the environment according to the law of the Republic of Indonesia Number 23 Year 1997 on the Management of environmental Life is a unity of space with objects, power, state, and living creatures, including human beings and their behavior mempenagruhi yag viability of human life and well-being and other living creatures. The environment, including natural resources, both globally, and nationally in the history of human civilization has sustained human life. B. Elements of the Environment Environment is oenting resource for human life and other living creatures. Environment is underpinned by three elements as the provider of all the needs of human beings and other living things. 1. Biotic elements Elements of biotic elements that are present in the environment are related to media such as mausia, animals, plants, and microorganisms. Biotic elements is very influential in our lives as if there were no elements of biotic then we do not bias ...

Burning waste is an activity that is detected to have a major role in air pollution. The process of burning waste even a small scale was instrumental in increasing the number of pollutants in the air, especially dust and hydrocarbons. It is important to take into account the emissions of air pollution by garbage is particulate emissions due to the combustion process, while emissions from the decomposition process that needs to be considered is the HC emissions in the form of methane gas. Substance or pollutant gases, it is not only harmful to the environment but also directly harmful to humans. Pollutants emitted from incinerators can lead to health problems, trigger cancer (carcinogens). As an illustration of burning 1 tonne of waste will produce 30 kg of CO gas, the gas if inhaled will bond very strongly with blood hemoglobin that can cause the body will lack the people who inhale O2 and causing death. Burning organic waste will also produce methane gas. Burning pieces of wood w...

Soil contamination is the state in which man-made chemicals in and alter the natural soil environment. Contamination usually occurs because: leakage of liquid waste or industrial chemicals or commercial facilities, the use of pesticides, polluted surface water ingress into the sub-surface layer, chemical substances, or waste. Water waste from landfills and industrial waste directly discharged into the soil ineligible. If a hazardous substance has polluted the soil surface, so it can evaporate, and the rain washed away or into the ground. Pollution that goes into the ground and then terendap as toxic chemicals in the soil. Toxic substances in the soil can have a direct impact to humans when in contact or can contaminate ground water and the air above it. Change Function of Land and Soil Pollution Shifting land use due to industrialization, the changing function of agricultural land has led to extensive water catchment areas in many parts of Indonesia. Besides the change of land...

             Pertumbuhan pembangunan di kota-kota besar misalnya Jakarta mengakibatkan jumlah ruang hijau semakin berkurang. Kerapatan dari bangunan-bangunan di perkotaan menngakibatkan jumlah ruang hijau semakin berkurang. Di setiap sudut kota bangunan-bangunan tinggi menjulang.kerapatan dari bangunan-bangunan di perkotaan telah melewati ambang batas ideal perbandingan antara ruang tidak terbangun dan yang terbangun. Kepadatan dan kerapatan bangunan di kota-kota besar secara tidak langsung ikut menciptakan dan menambah tingginya efek rumah kaca, berkurangnya luasandaerah hijau menyebabkan udara panas kurang terabsorbsi dengan baik sehingga terjadi apa yang dikenal dengan nama “ Urban Heat Island Effect ”. Suhu udara kota mengalami peningkatan tajam akibat dominannya material perkerasan yang tidak bisa menyerap sinar UV dari cahaya matahari dengan baik misalnya infrastruktur jalan, penggunaan mesin pendingin/ Air Conditioning yang mengeluarkan energ...
