Debus Art

There is a unique art in my hometown, Pandeglang. This art called debus. Debus art is one of the arts that comes from Banten Province, the province where Pandeglang is located. Debus art is an art that really different with other arts. It is not a dance, ceremony or something beautiful to see. Actually debus art is very dangerous. Debus art shows the abilities of its players about their body resistance. Example, in their show, they use knife, sword and other sharp tools then stab those to their part of bodies, like tongue, hand, neck and stomach. Also, they use sulphuric acid and pour it to their bodies. The strange thing is they don’t get injury at all when they do this art. What an ‘art’! . Is it real or is there a mystic thing works on debus art? I don’t know exactly. But the players on debus art are only certain people who have a tough belief to do this dangerous art and before they begin the show, they always do some ritual for their safety.

Water Distribution

In this house, there are two tanks of water, cold water tank and hot water tank. There are also four places that have to be distributed by those tanks of water, bathtub, wash basin, toilet, and sink. First, cold water tank as the main water tank, distributes the cold water into those four places (bathtub, wash basin, toilet, and sink) and also into the hot water tank. In hot water tank, the cold water from cold water tank is changed to be hot water, and then it distributes hot water to three places, bath, wash basin, and sink. So, cold water tank distributes the cold water directly to bathtub, wash basin, toilet, and sink. And the hot water tank gets the water from cold water tank and changes the water to be hot water before distributes to bathtub, wash basin, and sink.

Methan from Household Waste

Methane is a chemical compound that can be extracted from household waste. The process to extract methane starts with mixing the waste with water and stores it into the warming bed. When it reaches a certain temperature, methane will separate it self from the other compound of waste. While the waste can be use as a fertilizer, methane is transferred into the dirt trap. Here, a cap under the methane is open periodically so that the dirt that is still in the methane can be discarded. After the methane is clean of dirt, it is than piped into a Gas Indicator Unit. Here, the methane is mixed with water. When the gas indicator reaches a certain temperature and pressure, methane develops into gas. (The bubbles in water indicate that there is gas). When the gas rises it is then piped into the gas holder. Here the methane is stored for further use. When ever needed the methane can be used by just opening the holder’s tap.

Patin Curry

If you visited Pekanbaru you will find in many restaurants a dish called Patin Curry or in Indonesia called Gulai Ikan Patin. It is a specialty in this city and even in the Province of Riau. The main ingredient of Patin Curry is of course patin fish, coconut milk, curry powder and a little bit of spice. These main ingredients with other ingredients are than boiled until it is thick enough. This dish is very delicious and a unique taste with a mixture of the taste of coconut milk, spice and a little of sour. You really can’t describe the taste of this dish. So whenever you visited Pekanbaru, don’t forget to try it.

Water Distribution

Water distributions in all houses are relatively the same. Water is distributed from the main source into all parts of the house by pipes that are hidden in the floor and the walls of the house. Because of the different location of the facilities that needs water, to fight the gravity pressure, the water is pumped using a special machine. While cold water can directly distribute, warm or hot water can’t. The main source that only contains cold water than send parts of the water into a heater. Here the water is heated to a certain temperature. It is then piped into parts of the house. In every tap where hot water goes trough is a temperature box. This is used to arrange the temperature that comes out of the taps.

Sewage Disposal Unit

Sewage mostly contains potentially dangerous substances which can cause pollution if it is thrown away into the river directly without any purifying process. Sewage can lower the water quality in the river and create a hazard to public health. Therefore, sewage had to be processed in order to make the potentially dangerous substances less dangerous.

The process of purifying sewage is very simple to understand. There are three main places of treatment which hold three main process of purifying sewage, which are the settling tank, the pump house, and the sprinkler beds. In the first step, the sewage enters the settling tank through a main sewer. In the settling tank, after a several while, the undecayed solids will settle in the bottom of the settling tank, for then be removed and burned. The rest of the sewage will be absorbed into the pump house. From the pump house, the sewage will enter the sprinkler beds. There, the filtration process is hold. The sewage from the pump house will be sprayed by the rotation arm into the brick work which contains stones and microorganisms as the filter media. Rocks are one of the recommended media for sewage filtration because it do not fragment or soften on exposure to sewage. Microorganisms, in the other hand, adsorb nutrient from the sewage as food. Finally, after the process of filtration is finish, the purified water can enter the river.

Sewage Disposal Process

Sewage disposal process consists of three steps. They are settling, pumping, and sprinkling. First, the sewage which comes from the main sewer is passed to the settling tank. In the settling tank, the sewage is separated into polluted water and undecayed solids. The undecayed solids will then be removed and burned. After this separation, the polluted water will be pumped to the pump house. Then, the polluted water, which has been pumped, flows to the sprinkler beds which have jets of polluted water that lay on the brick work. The jets of polluted water are pipes which have rotating arms. Moreover, the jets of polluted water filter the polluted water from stones and micro-organism. After the filtration, the water which has been purified is now entering the river.

Extracting Methane Gas

Firstly, waste is put into the warming bed. In this bed, it is separated into 2 parts; the mixture of methane and the fertilizer. The mixture of methane is flowed to the dirt trap. Then it will be separated into methane and dirt, and releases cap. Next, the methane is directed to the gas indicator throughout the sealed top. In this container, it can be noticed as bubbles of methane in water. Afterwards, the methane is continued to the pressure release which has the top open to air. This container contents water and access gas when pressure high. Then, the methane is continued to the gas holder which has inner tubes and weight to increase gas pressure. Finally, after all of the processes have been done, the pure methane is produced and flows throughout the tap.

water circulation

Generally water from the ground is absorbed by the main pipe of the watering system. The main pipe divided to two pipes, pipe to the sink on the first floor and pipe to second floor. On the second floor the pipe divided to two main pipes. Actually the pipe that watering the first and second floor is cold water, so the water in the first main pipe on second floor flow to the cold water tank. This tank is save all the water that absorbed from the ground, this is the first step of watering all the room in the house. Water from the cold water tank divided into two groups. First, flow to the hot water tank, this tank used to boil the water from the cold water tank, and the water from the tank spread to be used in all room in the house. The second group, the water from the cold water tank directly spread to all room without boiled first.

The Process to Producing Methane Gas

Methane gas is extracted from household waste. This waste goes through several stages to producing methane gas. First of all, the waste is thrown into warming bed to be heated with the result that it will produce hot gas. Then, the hot gas rises to the top of warming bed and flows along the pipe that connected to dirt trap. In the dirt trap, the dirt that contained in the gas is precipitated. After the precipitation, the gas flows along the other pipe that ends in the water that put in the vessel with sealed top. In this stage, we can see the methane bubbles flying in the water. Then, the methane rises to the air in the vessel and flows into the pipe. This pipe is divided into two ways. First pipe goes to the inner tubes that equipped with the weight to increase the pressure. As the result, the methane is ready to use by opening the tap. Other pipe is used for excess gas when pressure high. This pipe ends in the water that put in the vessel with its top open to air.

Sewage Disposal Unit

Sewage disposal unit on figure 2 has three stages to purify the polluted water from the sewer. The first stage, called 'Settling Tank', is a place that settled for the polluted water from the main sewer. The polluted water will formed sediment there; so that the polluted water will be separated with the solids content in it. Later on, the undecayed solids will be removed and burned while the polluted water continue the process into the next stages. The second stage is a pump house that just pumping in the polluted water from the settling tank and distribute it into the springkler beds. On this final stage, the polluted water will be directed to the rotating arms. Later, the polluted water will be emitted into the air. Then the rest that falls down will be filtered of stones and microorganisms to yield the purified water that is save to enter the river.

Waste as a national problem

Waste is a public problem, and now even is getting larger to become a nation problem. One of the best solution to this problem is making an efficient waste disposal system. Our disposal system is not bad though, the main problem is could be the people and the community which are irresponsible to the environment.

Waste disposal itself has a complex system until it can be distribute back to the river. Water on river should be clean and hygiene. People obtain water from river for many use. Whenever the water is dirty, it can be dangerous for their health. Government must pay attention for this water usage by providing a waste disposal system before used water reach river. Clean and dirty water are meet at the settling tank. Here, all of the solid waste are removed and burned, the solid waste are usually drown at the bottom. At the end of this settling tank, there is a pipe to flow the water to the pump house. The function of this pump house is to pump the water outside and distribute it to the sprinkler beds. Water is having much of sanitation on this part. Before it reach river, the water must pass through all part of the sanitation system on sprinkler beds, this part is filled with brick and filter of stones and microorganisms.
