Water System in Modern House

Most house's water system are directly fed from a municipal water system, which usually located under the road or street. Water, from the municipal water system, are brought to each houses by high-preassure pipes. Water, which has been flowed to the house, are stored in the house water tank. From this water tank, water are flowed by the mains to reach every taps in the house.

Water are distributed by the mains to every part of the house. Through pipes, which are installed in the wall and floor, water are flowed to each house's components. First, water are distributed to reach sink tap and other taps in the first floor. After that, water are pumped up again to the second floor. In the second floor, water are distributed to reach wash basin tap, toilet tap, and bath tap. Last but not least, water are flowed to the loft and stored in the cold water tank.

Many modern houses use two kinds of water, which is cold water and heated water. Because water from the municipal water system is unheated water, this water must be processed first. In order to get the heated water, cold water, which has been stored in the cold water tank, is flowed to the hot water tank. Processing system in the hot water tank makes cold water contains heat. After that, this heated water are distributed to reach every taps in the the first and the second floor.

Minangkabau Cuisine's Trademark

Rendang is a traditional Indonesian cuisine which made from beef (or occasionally chicken, mutton, water buffalo meat, or vegetables like jackfruit or cassava), slowly cooked in coconut milk and spices for several hours, until the meat coated in the spicy condiments. This slowly cooking process allows the meat to absorb all the spices and to become tender. The spices, which are cooked together with the meat, are turmeric leaf, golongal, ginger, lemon grass, and chillies.
Rendang is one of the charactersitic foods of the Minangkabau culinary. It has been the icon of Padang food. Therefore, Rendang is provided in every Padang restaurants. Almost every people which eat in Padang restaurant choose Rendang for their main dish. Rendang has been of the Indonesia people's favorite.

Batagor

When we talk about Bandung, one of the things that across our mind is its foods besides the factory outlets. I believe in every step you take in this city you will find any tasty foods wether it’s just a snack or even a meal for your lunch or dinner. And batagor is one of the most well-known snacks in this city. It’s a perfect snack for your tea time. Batagor is stand for baso tahu goreng.

So if you’ve got a plan to visit this city, don’t forget to try this batagor.

Water Supply

The government provide our need of water through PAM (Perusahaan Air Minum). The water from all sources is been purified there. Then the pure water can be distributed through pipes to the houses. First of the water reaches the house it formed as the cold one. As we can see from the picture, the cold water from the mains can straightly distributed to the sink on the base floor besides its supplied to the upper floor. Then on the second floor, the pipe is affiliated into two direction. One into the cold water tank on the roof top; and the other one into the toilet, the wash basin, and the bath. To yield the hot water, the cold water from the tank has to distributed into the hot water tank at the second floor. Then it will be able to be supplied to the bath and the wash basin on the same floor as the hot water tank; and the sink on the base floor.

Sewage Disposal Unit

Here is the process of sewage disposal to the sprinkler in the field. First, the water from the main sewer is channeled to the settling tank. In the settling tank, the polluted water is separated from the undecayed solids. The undecayed solids settle in underside of settling tank. Then, the water (without undecayed solids) flow to the pump house. Afterwards, the water is pumped from pumped house to the sprinkler bed under the surface of the earth. The sprinkler bed is composed of pipeline and brick filled with stones and microorganisms. The water flows through pipeline to the surface of the earth. Along the pipeline, the water is filtered by stones and microorganisms. After that, the filtered water is spread to the field. Some of water is not spread, but flows to the river.

water distribution

The distribution of water which is used for household comes from underground. The water is distributed to the house by pipes and some of it is stored in the cold water tank, because the water from the ground still has a cold temperature. Some of the water is also distributed to the bath tub, wash basin, toilet, and also to the sink. Then the water from the cold tank is distributed to the hot tank where the water gets processed till it becomes hot water. After being processed, the water will get distributed to the bath tub, sink, and wash basin.

monumen nasional

'Monumen Nasional' which people usually call Monas is a unique monument in Jakarta. Monas is a monument which is very high and it is also a symetric monument. In the museum of this monument there are many historical things about the independence of Indonesia like photos of the days during the journey to independence and other historical things. There is also a room like an amphitheatre where inside it is kept a map of Indonesia, the flag of Indonesia, proclamation text, and other things related to the independence of Indonesia. The top of Monas is built from bronze and is covered by gold which looks like fire that symbolizes the journey of the people to the independence of Indonesia. Monas is one of the places where many tourists like to visit when they are in Jakarta, because people can see many things about Jakarta and also about the independence of Indonesia.

Water Distribution

Water that is used at home can be received from two kind of sources, PDAM or artesian well. Water is supplied to places in the house through pipes. Water that comes through the main pipes is distributed to several places in the house like sink, toilet, wash basin, and bath tub. Some of the water is placed in a tank called cold-water tank. Because the member of the house also needs hot water for several necessity, like taking a bath or washing, the water must be processed to become hot water. The way is by moving water from cold-water tank to hot-water tank through pipes to be processed. The heating process can be done in many methods, like using electricity or gas. The water from hot-water tank is then distributed to places in the house through pipes which need hot water like bath, wash basin, and sink.

Surabi

Surabi

is one of the traditional foods from my hometown, Bandung. Surabi is a traditional food made of the mixture of pulverizes rice, milk squeezed from coconut, and salt. The tool to make a surabi usually is a parabolic-shape made from clay. This tool is heated traditionally using a fireplace and coke. The way to make a surabi is very simple. Pulverizes rice, milk squeezed from coconut, and salt, which already well-mixed, heated on the fireplace until it’s cooked. Plain traditional surabi is usually enjoyed with kinca, a liquid made of red sugar and milk squeezed from coconut. Surabi also can be add with a topping named oncom, made of peanut, red pepper, and onion, to get the spicy taste.

Today, people make new variation with surabi, especially on the topping. The topping are now vary from cheese, strawberry jam, chocolate, egg, and chicken. This new variation of surabi is very popular, especially among adolescence. Making new variation of surabi is one of the ways to conserve surabi. With making new variation, surabi, as a traditional food, won’t be put at edge by modern food.

Extracting Methane From Waste

Extracting methane gas from household waste is relatively simple and could be done in any average home. The first step is to mix the waste with water and store it into the warming bed. In the warming bed the slurry part of the waste is taken and used as fertilizer, while the gas produced by the waste, called methane gas, is transferred into the dirt trap. Here, the cap under the dirt trap is opened periodically to release and separate the dirt from the cleaner methane gas. The cleaner gas is then piped to a water container or Gas Indicator Unit. When the gas indicator receives the methane gas, it then produces bubbles which indicate the purified methane gas is present and ready for storing. Before storing, part of the gas is piped in parallel to an opened water-container for gas release whenever the gas pressure gets too high in transition to the gas holder unit. Lastly, the methane gas then goes to the gas holder to be stored in the inner tubes, and is ready to use such as for cooking whenever tap is turned on.

Methane Process

Methane is a chemical compound with the molecular formula CH₄. It is the simplest alkane, and the principal component of natural gas, about 97% by volume. It is a colorless, odorless gas (at normal temperature and pressure) and not a liquid nor solid. The major source of methane is extraction from geological deposits known as natural gas fields.. Apart from gas fields an alternative method of obtaining methane is via biogas generated by the fermentation of organic matter including manure, wastewater sludge, municipal solid waste, or any other biodegradable feedstock, under anaerobic conditions. Here is a process of producing methane from waste as it main source.

To have purified methane gas, we have to separate it from other components of waste. This process has several posts. At the first post, warming bed, the waste is heated to separate it with other heavy components of waste. While methane goes to next process, the other waste’ components can fertilize your plants as it passes few processes. Then, at the next post, the dirt trap, the remaining dirt is separated from the methane by sedimentation. The dirt stays in the dirt trap and the gas flows to the next cabin, gas indicator. Half part of this sealed cabin is fulfilled by water and other by air. After the methane gas is flowed into the water, there will be methane bubbles. Other gas will be trapped in the water. The methane bubbles goes up to the top of the cabin and continue its journey to the next post. In this post, cabin is fulfilled by water until the top of the cabin which is open to air. The flower pipe enters the cabin about 8 cm in depth. When the pressure is high, the excess gas will flow into the water in the cabin and then goes to the open air. After all those process, the purified methane gas is flowed into the gas holder. It is kept in tubes which are weightened to increase the gas’ pressure. The flower pipe ends with a tap.Whenever we need methane gas, just open the tap and the gas will come out.

The sewage disposal and purification processes

The sewage disposal and the sewage purification processes is quite complicated but it is easy to be understood if we follow the processes step by step. These processes consist of the settling phase, the pumping phase, and the filtering phase. First, the sewage from houses must gets through several sewerage pipes before reaching the main sewer. After reaching the main sewer, this sewage is passed to the settling tank. At the settling tank, this sewage is settled so that the polluted water (the liquid form of sewage) can be separated from undecayed solids (the solid form of sewage which will then be removed and burned). After that, the polluted water, the liquid form of sewage, will be pumped by the pump house. The pumping process is meant to transfer the polluted water from the settling tank to the sprinkler beds in which the purification phase occurs. After a while, the pumped polluted water reachs the top of the sprinkle beds, that pumped polluted water disperses when it meets the rotating arms. That dispersion produces jets of polluted water which head for the sprinkle beds’ layers that lay between two sides of thick brick work. Then, the jets of polluted water slowly infiltrate the layers, the layers act as filters which purify the polluted water from stones and microorganisms. The result of the purification is the purified water which will be flowed to the river as soon as it has been accumulated thoroughly.
