E.Coli Analysis of Settlement without Slums in Deli River

Escherichia coli is a biological indicator of air pollution. The presence of E.Coli in water proves that the water is contaminated by human and animal feces. This is more important than faeces or feces which also contain other pathogenic enteric microorganisms. E.Coli becomes a pathogen if the number of these bacteria increases or is outside the intestine, one of the human digestive systems. Therefore, E.Coli produces enterotoxins which cause several cases of diarrhea (Brookset al., 2004).E. coli is also one of the bacteria from microflora found in the digestive tract of humans and animals. E. coli is a heterotrophic bacterium that obtains food in the form of organic substances from its environment because it cannot compile the organic substances it needs. This organic substance is obtained from the rest of other organisms. E. Colli breaks down organic matter in food into inorganic substances, namely CO2, H2O, energy and minerals. In the environment, these spoilage bacteria function as decomposers and provide nutrition for plants (Kusuma, 2010). Transmission of Escherichia coli which causes diarrhea through water polluted from faeces. In addition, transmission also occurs through contact from infected workers while the food is being processed so Escherichia coli can be one of the causes of foodborne disease, which a disease is caused by consuming contaminated food or drinks. Deli River is one of eight rivers in the city of Medan. Initially, during the Deli kingdom, the river was a vein of trade to other regions. At present, the forest area in the upper reaches of the Deli River is only 3,655 hectares, or only 7.59 percent of the 48,162 hectares of the Deli River Basin area. In fact, with an area of 48,162 hectares, a length of 71.9 km and a width of 5.58 km, besides that, waste now pollutes the river. Deli River pollution, 70 percent of which is caused by solid and liquid waste. Sungai Deli is now changing its function as a long and wide trash bin. The riverbank community uses the river besides for Abstract

bathing, washing, drinking and cooking, it is also used as a place to urinate and defecate, as well as a place for garbage disposal.
Law Number 1 of 2011 concerning Housing and Settlement Areas states that Slums are non-habitable settlements due to building irregularities, high building density, and the quality of buildings and facilities and infrastructure that do not meet the requirements. The condition of the facilities and infrastructure does not meet the requirements (facilities and infrastructure limits are set within the scope of the craft), namely: Environmental Roads, Environmental Drainage, Water Supply / Drinking, Waste Management, Waste Water Management, Fire Protection The area of Hamdan settlement is 14.93 hectares while the total area of the village is 52 hectares with a population of 2736 people who have a low-income community of 255 RT / person. The people of Hamdan Yang Village adjoining Deli River have access to family toilets by 38%. This forced the community to dispose of their faeces directly. Although there are some people who use septic tanks, disposal will go directly to the river faster and this will affect the biological indicators of river water pollution, especially E. Coli.

Clean / Drinking Water Quality Standards
Minister of Health Decree (Kepmenkes) RI No. 907 / Menkes / SK / VII / 2002 Concerning Requirements and Supervision of Drinking Water Quality, states that drinking water is water that has been processed or has no processing that meets health requirements and can be drunk directly. The types of drinking water include: a. Water distributed through pipes for household use. b. Water distributed through water tanks. c. Bottled water. d. Water used for the production of food and beverages served to the public. The four types of drinking water must meet drinking water quality requirements that include physical, chemical, bacteriological and radioactive requirements.

Water Treatment Unit
Water treatment is defined as a technical operation carried out on raw water in order to become clean water that meets the quality requirements as clean water / drinking water by combining several treatment processes. Water treatment aims to reduce the concentration of each pollutant in water so that it is safe to use. According to Reynolds (1982 p. 1) the operating units and process units used in water treatment are as follows: a. Physical treatment includes sedimentation, flotation and filtration. b. Chemical processing includes coagulation, flocculation, adsorption, exchange ion and chlorination. c. Biological treatment includes aerobic digestion and anaerobic sigestion.  Montgomery, 1985;AWWA , 1998 (*)

Escherichia Coli
E. coli is a facultative anaerobic Gram-negative bacterium and cannot form spores. This bacterium can live on various substrates by performing anaerobic fermentation to produce lactic acid, succinic, acetic, ethanol, and carbon dioxide (Anonymous 2008) .E. coli belongs to the family Enterobacteriaceae, in the form of a stem or coma, there is a single or paired in a short chain. (Whittam., Et al., 2011 A small proportion of patients with E. coli type STEC can be affected by complications of Uremic Hemolytic Syndrome (HUS). This condition is caused by toxins from the E. coli bacteria. The poison is then passed into a vein and sent to white blood cells to the kidneys. As a result, sufferers can experience acute kidney failure, pancreatitis, seizures, and coma. This complication is more common in children aged 1-10 years and the elderly, compared to adults.

e. Prevention of E. coli infections
Application of a clean lifestyle to prevent dangerous Escherichia coli infections. Here are some ways that you can do everyday: • Wash hands immediately after leaving the bathroom and after changing a child's diaper. • Wash hands before and after preparing food.
• Wash hands after touching animals or working in an environment with many animals, such as in a zoo or a farm. • Make sure items that will touch the mouths of infants and toddlers, such as pacifiers and teether, are clean. • If there is no water and soap, use a hand sanitizer that contains alcohol at least 60%, to reduce germs on the hands. • Cook meat until cooked and wash all used cooking utensils, to prevent exposure to harmful E. coli bacteria from food.

Kel   The table above can be concluded that E. Colli and Total Coliform are above the established quality standards, therefore it is necessary to treat water before spatial planning. One of the requirements for clean water quality is biological factors, namely E. colli and Total coliform bacteria.
Alternative water treatment needs to be done before structuring buildings around the river location. AWWA, 1998 states that if the bacterial quality standard above the specified quality standard is by processing filtration and disinfecting. The arrangement that needs to be done next is to make a bathroom around the river location. E. Colli, which is identical, comes from fecal matter, so there is a need for public bathrooms around the river. This is done to save the quality of river water. The existence of a public bathroom into an organized arrangement of sewage. E. coli cannot be killed by cooling or freezing, this bacterium can only be killed by antibiotics, Ultraviolet (UV) sinau, or high temperatures> 1000 C. High temperatures will damage the protein in cells and make it unable to live again. Nongenetically engineered (wild type) E. coli generally cannot survive if there are antibiotics such as amphicillin and chloramphenicol (Girard et al., 2003) even with antibiotics such as Amoxicillin are sufficient (derivatives of amphicillin which have lower killing power). In general, these bacteria can be found in the human large intestine. Most E. Coli are harmless, but some like E. Coli type O157: H7 can cause serious food poisoning in humans, namely bloody diarrhea due to the exotoxin produced called verotoxin. Disinfection is a water treatment process to kill pathogenic bacteria using disinfectants. Affixing the disinfectant is usually done after the filtration unit and it takes a sachlor chloride of 0.2-0.5 mg / l thereafter to be distributed to the distribution network (PP No. 82 of 2001). Some types of disinfectants that are often used in the process of removing microorganisms, namely ozone, ultraviolet radiation and chlorination. However, a disinfectant that is commonly used in Indonesia is calcium hypochlorite [Ca (ClO) 2] or chlorine, because the price is relatively cheap, is stable and can be stored longer (Said, 1999). DBP is a chlorine reaction with organic compounds contained in raw water, DBP can cause cell damage and is carcinogenic, so it is necessary to determine the right disinfectant dose so that the disinfected water is free of DBP (Rice, 2009). The effectiveness of disinfection can be influenced by the presence of other compounds, including ammonia, nitrites and nitrates. This compound can reduce chlorine disinfectant performance because d-synfectant will react first with ammonia and nitrate before the disinfection process with bacteria (Metcalf and Eddy, 2007).
The number of bacteria in ground water (well water) in Indonesia varies considerably between 5 to 1000 MPN / 100ml. 10,000 MPN / 100 ml exceeds the number of bacteria found in the gutter. The dirty water will smell and also cannot be used for bathing. For comparison, 10 thousand MPN per 100 ml is equal to 1000 human waste in one swimming pool. (http://oasisdesign.net/water/quality/coliform.htm). Water conditions polluted by E.coli can be treated with water to reduce levels. So that polluted water can be consumed.

Figure 7. Water Treatment System
Pathogenic microorganisms in water can be phased out in drinking water treatment and enhanced. The number of bacteria in ground water (well water) in Indonesia varies considerably between 5 to 1000 MPN / 100ml. 10,000 MPN / 100 ml exceeds the number of bacteria found in the gutter. The dirty water will smell and also cannot be used for bathing. For comparison, 10 thousand MPN per 100 ml is equal to 1000 human waste in one swimming pool. (http://oasisdesign.net/water/quality/coliform.htm). Water conditions polluted by E.coli can be treated with water to reduce levels. So that polluted water can be consumed. by disinfection process (Tchobanoglous, 2003). Disinfection is a water treatment process to kill pathogenic bacteria using disinfectants. Water purification of this water purifier goes through 4 stages namely: micro fiber filter, activated carbon filter, germ killer processor and purifier. Micro fiber filter works to remove visible impurities. Micro fiber filters can filter out coarse particles that can be seen by the eye up to 0.1mm in size. E. micoli diameters 0.5 micrometers so with a larger micro fiber size can not inhibit E. coli. So E.coli still contaminates water.
To reduce E.Colli polluted in river water, public facilities are needed, including public bathrooms. Bathroom activities are adjusted to the activities of bathing, washing and toilet (MCK). The bathroom is made based on gender, male and female. The location of the bathroom is placed close to the river to facilitate drainage of clean water and dirty water. Freeing up bathing activities required a large tub. Another tub is also needed for washing activities. The design of the arrangement of clean water and wastewater is needed to reduce the incidence of water pollution due to E. Colli. The position of water treatment is placed close to the river, while the position of waste after bathroom activities takes place.

V. Conclusion
The conclusions of this study are: 1. Analysis results of E. Colli Laboratory amounting to 21420 -36540/100 ml, still above the quality standards set by PP No.82 of 2001 concerning the management of water quality and control of water pollution. 2. The results of the analysis of Total Coliform Laboratory of 198630 -241960/100 ml, are still above the quality standards set by PP No.82 of 2001 concerning the management of water quality and control of water pollution. 3. Alternative water treatment needs to be done before structuring buildings around the river location by means of filtration treatment and disinfecting. 4. The arrangement that needs to be done next is to make a bathroom around the river location.
