Sewage Disposal Unit

Sewage Disposal Unit

Sewage disposal unit works in a simple mechanism. First, sewage from houses, factories, and other places flows through the main sewer to the settling tank. Then the sewage will separated into two forms, the undecayed solid waste and the polluted water. The undecayed solid waste which is settled at the bottom will be removed from the settling tank and burnt outside. Meanwhile, the polluted water is pumped from the pump house to the sprinkler beds. Next process, the polluted water is pumped out to the rotating arms, where polluted water is sprayed to the brick work. The brick work filters the polluted water from stones and micro organisms. The filtered/purified water can be safely flown to the river.

Process Paragraph:

HOME WATER SYSTEM

Actually, water system in a house used hot and cold water is very simple. First, water from main source is pumped into the house through main pipe. This water is called cold water. The main pipe is branched, so some of this water flows directly into sink, toilet, or others appliances, while another flows to main water tank to be kept. Then from this tank, water flow to heater tank. In heater tank, water is processed using electricity to become hot. Next, this hot water flows to washbasin, sink, and other appliances, except to appliances which don’t need hot water in used. Finally, people can choose what water they want to use.

Sewage Disposal Unit

The sewage management system consists of three stages. First, sewage from the main sewer is channeled to a settling tank. In this stage, the sewage is precipitate. After a while, the undecayed solids are left at the bottom of the tank and then the polluted water is distributed to the pump house. Then the pump house pumps the polluted water to the sprinkler bed. The sprinkler bed is a filter of stones and microorganisms, surrounded with brick work on its outer part, and on top of the filter are rotating arms. Polluted water is pumped to the top of the sprinkler bed through the T-shaped pipe and creating jets of polluted water in the air, which then fell to the filter inside the sprinkler bed. The polluted water was here purified. Then the purified water was flown to the river.

Water Distribution System

In the picture we can see a water distribution system in a two-story house. The water distribution in this kind of house is quite simple. Water from the PDAM is pumped to a water tank at the top of the house and then from there the water is distributed throughout the house. The first destination is the kitchen that located on the fist floor. The second is the bathroom’s stuffs on the second floor. The last is the cold water tank that connected to the hot water tank. In the hot water tank, the cold water from the cold water tank will be warmed. When the water is warm enough, the water will be distributed to the bath and wash-basin in the bathroom, and to the sink in the kitchen.

Parai Tenggiri Beach

One of the most beautiful beaches in Bangka is Parai Tenggiri Beach. It is one of Bangka Island’s prides. It is located in Sungailiat district. The visitors can find various forms of boulders in this beach, which add its beauty. This beach is very ideal for swimming, sun bathing and relaxing. It also has the most complete facilities in Bangka Island such as luxurious hotels and water sport facilities. The calmness and fresh sea wind will greet the visitors when they arrive there. The beauty of this beach makes the tourists feel comfortable to stay.

Sewage Disposal Unit

Sewage cannot be disposed directly to the sea or river so the water that contains sewage must firstly be purified using a sewage disposal unit. The process in a sewage disposal unit starts with the polluted water being flown to the settling tank through the main sewer. In the settling tank, the undecayed solid is separated from the polluted water and stays on the bottom of the tank where it will then be removed and burned. After that the polluted water is flown to the pump house where it will be pumped to the sprinkle beds. At the top of sprinkler bed there are rotating arms which spray the polluted water that flows through the rotating arms to the filter. The filter is made of bricks at the outer part and contains stones and micro-organism with which the polluted water is purified and finally ready to be directly flown to the sea or river

Sewage Disposal Unit

Sewage Disposal Unit, a system to purified water, consists of some stages. The first stage is where the water flows from the main sewer to the settling tank. The purpose is to remove the undecayed solids from the water. Next, the water goes to the pump house which pumped the water to sprinkler beds. The rotating arms make jets of polluted water. After that, the water is filtered to separate the stone and microorganism. Then the purified water is flowed back to the river.

Methane Extraction from Househod Waste

Extraction Methane

We can make methane gas from our household waste like our pup, garbage, dry branches and leaves, and etc. Firstly, we must put the waste into one kind of tube that we called ‘warming bed’. After we put into the warming bed, the water will be fertilized and the residue from fertilization, which is methane source, will go to the dirt part. In the dirt part, the methane source will be divided into dirty methane gas and the garbage which is no longer contains methane. The garbage can be taken from ‘release cap’ in the bottom of dirt trap. Then, the dirty methane gas will go to ‘gas indicator’. This indicator contains water which will be given with dirty methane gas and then the liquid will be separated into dirty water and methane liquid. Because of the mass difference, the methane liquid in the top of the water and this liquid will flows and divide into two pipes. The first pipes bring the methane liquid into the ‘pressure release’ which contains water. The water in this tube will contain methane liquid and methane gas will be produced when the temperature rising to the methane‘s boil point. The other pipe will bring the methane liquid into the ‘gas holder’ which contain tap so methane liquid can flow.

Working Children

Nowadays, we can see many underage workers in our surrounding. We can see in the streets, and public facilities. Commonly, they work as lift laborer in the market, or as streets beggar. This affair can be happened because family’s economic conditions which can not handle family’s needs so the family’s child must take a job as breadwinner beside father. Even, there is some child who quit from school because they want to maximize their income from their job.

Until now, there are many regulations which forbid the existence of working children in Indonesia. Yet, many people doesn’t know or realize the regulations because lack of socialization to people from government. In addition, government look like do not care to this affair. Irresponsible acts of government can make the future of children forced to work in Indonesia will be just a not coming dreams. Even, they can risk their life because their works is dangerous. Based on sheet from PUBH in 2005, there are 200000 working children have bad injury when do their work, from the entire world.

Now, what we can do to help them are minimalism the amount of underage workers like giving scholarships to children from poor family and giving economic aids to poor family. Government must be responsible and not closed their eyes to this affair because their acts will make international party give our country bad opinion. This problem will ashamed our country in the eyes of international

Water Process in House (task 2)

This is how the water goes to our house. Water from underground is pumped to reach the top of the house. Water goes into the sink and roof where the cold water tank is. Through the pipelines, water is flown to the bath, wash basin, and toilet without any process. From, the cold water tank, water is also flown to the hot water tank to be heated. From this tank, hot water is flown to the sink, wash basin, bath, and toilet. And water is ready to used.

Sewage Disposal Mechanism

Sewage from factory which contains dangerous materials needs some treatment before flown into the river safely. The method to treat the sewage is Sewage Disposal Mechanism. First of all, the sewage will be flown to the main sewer. From the main sewer, the sewage will be flown to the settling tank where the sewage will be separated in two forms. Solid matter which is sediment at the bottom will be removed and burned. Through the pump house, the liquid sewage which means polluted water from the settling tank is flowed to the sprinkler bed. In this bed, water is pumped by the hydraulic and water will reach the surface of the sprinkler bed. Then, water will be rotated by the rotating arm. The polluted water is filtered by contacting stones and microorganism with the water. Finally, this clean water can be flown to the river.

task 4

Nowadays we can extract methane gas from household waste with some simple steps. First, the waste from household was accumulated in the warming bed. From this warming bed, the waste will be separated for two kinds of usages, as a fertilizer, which can be used directly without any further process, and as a main material for the methane extraction. For methane extraction, the household waste goes directly to the dirt trap. The dirt trap will cause the methane separated from other contents of the waste. Then, the methane, which is in liquid phase, flows into gas indicator. Here, the methane is checked whether its gas is still produce or not by seeing the bubbles in water. After that, the methane gas flows into two pipes. The first pipe distributes the gas to a pressure release tank in order to decrease the pressure of gas, while another pipe distributes the gas to the inner tubes (with weight on the top of it) in order to increase the pressure of the gas. At the end of this pipe, there is a tap which controls the output of the extracted methane gas. Methane that comes out from this tap is ready to use.

Sewage Disposal Mechanism

Sewage cannot be thrown directly in the environment. Because of dangerous material that contain in the sewage, it need some treatment before its waste. In a Factory, there is method name Sewage Disposal Mechanism to treat the sewage. Sewage Disposal Mechanism in a Factory is doing in a few steps. First, sewage from the factory will be flown to the main sewer. From the main sewer, it is flown into the settling tank for a while. In the settling tank, this sewage will be separated in two forms. Solid matter from the sewage will be sediment under the settling tank before it’s removed and burned. The liquid matter is flown to the pump house by some kind of pipe. Then it is flown to the sprinkler bed. The sewage entered the sprinkler beds from the bottom to the top. On the top of the sprinkler beds, there is some kind of t-shape pipe names rotating arm. When the polluted water reaches the rotating arm, it will be sprinkler so the water can be spread in the surface of sprinkler beds and flown into it. In the sprinkler beds, there are some kind of filter made by layers of stones and microorganism. When the polluted water came through, it will be filtered so the water that came out from the sprinkler beds will pure and free from dangerous material. After that, the pure water can be flown and join into the stream of river safety.

Bogor –my hometown-has many interesting place and the most famous place is Bogor Botanical Garden. Bogor Botanical Garden is large area ( cover more than 80 hectares) of the original rainforest that contains more than 15.000 species of trees and plants, 400 type of palm, 3000 orchids, and 50 different varieties of birds and bats. The bats can be easily detected by the noise they make while competing for space under the canopies. The gardens officially opened in 1817 by German–born Dutch Botanist, Professor Casper George Carl Reinwardt and were used to research and develop plants and seeds from other parts of the Indonesian archipelago for cultivation during the 19th century. This site was also used by the Dutch for introducing tropical plants from other parts of the world into the region and served as a training ground for specialists in tropical botany., providing excellent specimens for scientific study.. Now Bogor botanical garden is known as a great natural recreation not only for Indonesian people but also tourist in around the world and the most important Bogor Botanical Garden reputation as a major center for botanical research makes people in all part of the world give their respect for our country.

The distribution water in our environment especially in our house is quite easy to be learned. First water from water source, for example ground water or aquifer, is pumped in pipeline system by water provider like PDAM in Indonesia to customer house. Next water in house pipeline system with cold condition move in three direction. First direction is sink in lower part of house, two others direction in the upper part of house. Second direction located in upper part of house are toilet, wash basin,and bath. Last direction also located in upper part of house is cold water tank .In this tank cold water can be storaged or move into hot water tank. Cold water can be converted into hot water. The hot water can used in bath and wash basin. So people can choose water condition for they need.

TASK 2

CHILD LABOR :

Unexpected condition

Industrialization era not only gives many advantages but also gives problems. The most serious problem is childs forced to be worker in factory and manufacture. The International Year of Child claimed that more than fifty million children below the age of fifteen working in varios jobs under hazardous conditions They usually do simple task and support their parents work, for example in shoe factory, textile factory, and cigarette factory. Although they can support their parents, child labor only gain little money for their contributions.

Child labor grow in unexpected condition, it means that children labor must barter their childhood with something that they should not have know in earliest stage of their life, working world. Child Labor lose their play time with their friends and it makes their social intelligence development very poor. Child labor also lack of education especially formal education, like kindergarten level, primary level, junior and higschool level also college level. The lack of formal education make their intelligence to anlyze and solve the problem is below average normal child in same age. Consequently they can’t compete others person who have formal education to get job and can’t make their life better. The last unexpected condition is child labor usually live in unhealthy environment, inadequate food, decentless shelter, and lack of clean water. These unexpected condition must be faced by child labor to stay alive.

The quantity of child labor is increase every year and sure it is bad news, not only for underdevelop country but also develop country . The effort to eliminate child labor expansion come from the International Labour Organization, sepecial agency of United Nations and founded in1919. This organization has introduced several regulations among its members,including a minimum age of sixteen years for admission to all work, a higher minimum age for specific type of employment , compulsory medical examinations, and regulation of night work. Although these regulations was made to solve child labor problems, The International Labour Organization can’t make ILO’s members enforce these regulations because the member nations have strategical and political policy in their nations. Moreover that is important if all of part of the world aware and care about labor child problem and give contribution to minimalize it.

Sewage Water Purification Management

Sewage water purification consists of three parts sewage management that starts from main sewers. Firstly, from the main sewer, sewage is distributed to a settling tank. Here, undecayed solid materials are left on the bottom of the tank and separated with polluted water. Then the polluted water is pumped to pump house. After the polluted water passed the pump house, it is distributed to a sprinkles bed. In this part, the polluted water from pump house are flowed up to jets and rotated with rotating arms. Then the polluted water is filtered from stones and microorganisms, so it will make the water more purified. Lastly, the purified water from the sprinkles bed enters the river.

Sewage Disposal Unit

Dangerous liquid sewage from the industry can be processed through purification process in the sewage disposal unit. Generally, the sewage will flowed into three main parts of the sewage disposal unit. First, the sewage from the main sewer flowed into the settling tank. In the settling tank, the undecayed solids from the sewage will stay in the tank base. Then, it’s removed and burned. Then, polluted water from the settling tank is flowed into the pump house. Then the polluted water is pumped from the pump house to the sprinkler bed. In the sprinkler bed, the polluted water is flowed to the rotating arms. Then, the polluted water is sprayed rotationally to the top surface of sprinkler bed. Then, it’s purified by the filter which contain stones and micro-organism. Finally, the purified water is safe to be flowed into the river.

Model Essay

Examination not assessment
In the past two decade, the use of formal examinations has become less frequent in many countries. The educational systems in some societies however are still dominated by formal examinations. I believe that, to a certain extent, examinations can give an unfair assessment of a student’s ability. Even thought examination result has been used extensively as a means of assessment in the past, there are times when they do not appear to reflect a student’s ability accurately.

Firstly, examinations can be unfair in several ways. For example, that whole career of a candidate depends upon what he or she does on a certain day and hour of an exam. If the candidate is ill, or if he or she has had some emotional trauma, these factors could have a negative effect on the student’s exam results. Furthermore, some students do not perform well under pressure and require a longer time to reach useful conclusions. Even though they may have studied diligently and know the subject matter thoroughly their performance does not reflect their ability. For these students, examinations appear to be unfair.

Yet, some people believe that examinations make people work hard. They assume that in order to do well, students need to work throughout the course as they know they will have to prove themselves at the end.

However, in many ways, exams have the opposite effect; some candidates merely cram so that they can perform quickly for the demands of the tests. Other forms of assessment such as course work and oral presentations are a more accurate reflection of how hard students work. In the assessment of their ability, students diligence, initiative, deductive reasoning and organizational skills are considered, which are important indicators of ability but are rarely tested in a formal examination.

In conclusion, even though formal examinations have been used in the past, they should no longer be used as the only means of assessment because they can be an unfair indication of the student’s overall ability. In the long term, other less formal means of assessment such as course work or oral presentations are a more useful indicator of the skills required in adult life and, therefore, a more accurate indication of a student’s ability.

TASK 4

Sewage usually dangerous for the nature, so we need a process before the sewage can be disposed freely to the river going to the sea. “Fresh sewage” from the sewer was collected in the settling tank. In this tank, particles heavier than water fall to the bottom of the tank, then it will be removed and burned. The polluted water that its solids have been removed was pumped through the pipes to the surface where there’s a filter. The polluted water comes out from the sprinkler so the water can be spread over the filter’s surface. The filter consists of several layers of stones and microorganisms. Polluted water will flow through those series of layers and was collected under the filter. The result of this process is purified water which is safe to be disposed in the river or sea.

Sewage Disposal Unit

The best way to waste the sewage is use a sewage disposal unit. In the sewage disposal unit, sewage can be changed to the purified water. First, sewage from main sewer is flown to settling tank. In there, sewage is separated to be polluted water and the undecayed solid will settle at the bottom of the settling tank. The undecayed solid is removed and burned. Next, the polluted water is flown to pump house. After that, the polluted water is pumped to the sprinkler beds. The outside of sprinkler bed is made of brick work. At the top of sprinkler bed there are rotating arms which can sprinkle the polluted water into sprinkler bed. After polluted water get into sprinkler bed, the polluted water is filtered and finally the polluted water is changed to be purified water and is flown to the river.

Simple Methane Production from Household Waste

Household waste can be processed to be methane in simple systems. First, in this system, the waste is put into the warming bed. In the warming bed, the waste is fermented by methanogenic bacteria resulting in raw methane. The side product can be used as fertilizer. The raw methane flows through a pipe into dirt trap. In his place the pure methane and dirt are separated. The methane which is lighter occupies the upper side and heavier dirt will reside at lower side. Then the pure methane flows into half-water-filled and top-sealed tube called gas indicator. The bubbles in the water indicate the existence of methane. The methane fulfills the rest of the tube and become saturated. After that, the methane flows to the next pipe that is also connected to the gas indicator. The methane then experiences increasing of its pressure due to the inner tubes that is loaded by weight. Now the methane can be taken from the tap at the end of the gas holder. If the pressure of the methane is too high, the excess gas will flows to a top-opened and water-filled tube. In this way the excess gas can be released to the air so the stability of the system can be maintained.

Sewage Disposal Unit

The process of disposing sewage in the sewage disposal unit is quite simple. First, the polluted water is flown to the settling tank through the main sewer. In the settling tank, the polluted water is separated from the undecayed solids that is stays in the bottom of the tank. After the separating process, the undecayed solids is removed from the tank and then burned while the polluted water is flown to the pump house. In the pump house, the polluted water is pumped to the sprinkler beds, which is the last part of the process. In the sprinkler beds, the polluted water flows through the rotating arms. The speed of the rotating arm makes the polluted water that flows through become a jet. Then, the jet of polluted water is sprayed to the filter that made of bricks and contains stones and micro-organisms. When the water flows through the filter, the stones and micro-organisms filter and purified the water. After that process, the water is ready to enter the river.

Sewage Disposal Unit

A sewage disposal unit doesn’t work in a complicated way. First, waste mostly comes from houses flows through the main sewer to the settling tank. In the settling tank, the waste is separated into two forms, the undecayed solids waste and the polluted water. The undecayed solids waste are removed from the settling tank and burnt outside, while the polluted water is distributed to the pump house. The second process is taken in the pump house. The polluted water is pumped from the pump house to the sprinkler beds, where the purifying water process is taken. Next, the polluted water is pumped out to the rotating arms which have jets to rotate them. The polluted water is sprayed out of the rotating arms to the brick work. The brick work is a part of the sprinkler beds which has a function to filter the polluted water from stones and micro-organisms. After the water is filtered, the purified water is distributed to river.

ANGKLUNG – UNIQUE BUT UNIVERSAL
Angklung is a universal musical instrument. It includes many aspects of nature and social. The nature aspect is that angklung is made from natural material which is bamboo. Angklung’s social aspect is that it has to be played by a lot of people because every angklung has a different size and only has one specific note. Angklung is very easy to be played, so everyone from every age can play it. The other universality of angklung is that it can be performed not only traditional music, but also all genre of music, such as classic, jazz, and pop. This musical instrument can also be combined by other musical instruments, not only traditional musical instruments, but also modern or classic musical instruments, such as contra bass, bass drum, and cymbal, to create an angklung orchestra. Nowadays, angklung is also well-known in other countries, such as Japan, Germany, and countries in South-East Asia.

HOW TO DISTRIBUTE WATER IN THE HOUSE
Distributing the water in the house is not very difficult. First, the water is pumped from underground by the water pump. Then, some of the water is distributed to the cold water tank while some of the water is directly distributed to house devices, such as sink in the kitchen or to the bathroom. Next, in the bathroom, the water is distributed to various devices. It is kept in the toilet, wash basin pipe, and also in the bathtub pipe. After the water reaches the cold water tank, some of the water is distributed to the hot water tank to be heated. Last, the hot water is distributed through the pipe to the bathtub pipe, wash basin pipe, and sink whenever the taps are opened.

Methane

Now, we can produce methane from the waste by number of stages. First, wastes from house collect in a big tank which is named warming bed. In this tank, waste are separated as fertilizer and methane formula. Then methane are flew to the dirt trap. Dirt from the methane are separated. After that, methane that is in liquid reform to gas by the gas indicator. Next, methane flow to the preassure release. In this tank, excess gas release from methane. And the last, methane is pumped out of the tap by put weight on the linear tube which put in the methane's way.
