Child labor
Most of them are children from a poor family and some of them is also a vagrant.
How could those things happened, while the government have promised their citizen’s prosperity?
There’s a law says that poor clan and the homeless will be protected by the government.
I wish they still have their sentimentality to stop the child labor. If the child labor is running constantly, there will be much more side effect, for example a child trafficking transaction.
Children are our asset to build and develop our state, Indonesia. It’s a good idea to save them and let them improve themselves. Let them explore what they want to expand, not just doing something because of their needs of funds. A child’s right is not being an occupied labor, but they have to be an educated person so they can be an intellectual labor.

How to Make Glasses
Plate glass and bottle glass are two types of glasses that usually used. There are several steps to make these glasses. First, all tools and materials for making them like sand, soda, limestone, furnace, rollers and removable mould are prepared. After that, sand, soda, and limestone are mixed together in the furnace. Then, they burned until the melted is shaped. After that, the melted is ducted into two stripes, first stripe is for making plate glass and second stripe is to make bottle glass. For making plate glass, the melted in first stripe is kept in a big pan and then it ducted into rollers. Finally, the plate glass is shaped. To make bottle glass, the melted in second stripe is given an air, then it ducted into the removable mould. Finally, bottle glass is shaped. Last, these glasses are ready to use.
how to make a glass
First, you should prepare the materials, including sand, soda, and limestone. We also need an equipment to prepared, such as a furnace to bake the dough that we may already made.
Next, we make a smooth dough by mixing the materials in an enough composition then put it into a furnace to be baked and mixed.
Inside the furnace, there is a branch that separates two kinds of glass that we want to make.
Some of the dough will be a bottle glass and the rest of them will be a plate glass.
If the dough flow to be a bottle glass, it will fall through and formed inside the removable mold. During the process, the air will also fill in the mould.
Meanwhile, the rest dough will fall into a bucket that has a hole beneath.
They will flow through the hole and performed under the roller. After that, we may dried off the glasses. Finally, the glasses are ready to use.
How to Make The Desired Glass Shape
The key idea in making various shape of glass is to melt the materials so that we can simply form it as we want. Two kinds shape of glass are plate and bottle glass. There are several steps to make these products. First, the materials—sand, soda, and limestone—are mixed in furnace. Then the mixture is heated up so that it is melted and really unified. After that, the mixture is flown into two channels. The first channel is for making plate glass. Through this channel, the mixture is poured into a tank then flown again into plate-shaped hole at the bottom-side of the tank. In this process, to make sure the mixture becomes really plate-shaped, the rollers are used to flatten it perfectly. Finally, the plate-shaped glass is formed. In the second channel, the mixture is desired to be bottle-shaped glass. It is poured into the removable mould which the part-inside has been bottle-shaped. The mixture, of course, also becomes bottle-shaped. At this bottle formation process, air is blown into the part-inside of the mixture. It is needed to produce such a proper pressure so that the inside layer of the bottle-shaped mixture becomes soft and smooth surface. The softer and smoother layer of the products; the better quality it is. After a few hours, the bottle-shaped mixture is cooled down and then the removable mould is removed from it. Finally, the desired bottle glass is ready being used.

Glass making process
The glass can be found in several shapes. The picture show us how to make plates and bottle glasses. First, sand, soda, and limestone are mixed and heated in a furnace on a high temperature. Then, the molten is distributed through separate ways, one way for glass plate, and the other for glass bottle. In making glass plate, the molten is entered into a tray as a terminal, then rolled in order to get flat shape, and finally cooled on the fresh air. In making bottle glass, certain pressure is given when the molten fills the tray because air is needed to help the molten covers only the wall of the glass. Similar with the glass plate, the moltened bottle glass is cooled until it becomes solid.

Glass-making
To make glass, you would need some materials and tools. The materials are sand, soda, and limestone. The tools are furnace, removable mould, rollers, and connecting pipes. First of all, sand, soda, and limestone are mixed in certain composition. Then it will be burnt in a furnace with an extremely high degree of temperature. The next step you have to do is to decide what shape the glass is going to be. If you want to make a plate glass, then the glass is channeled by connecting pipes to the roller. Certain pressure is given by the roller to make the shape of the glass plate. If you want to make a bottle glass, then you should channel the glass to a removable mould bottle-shape. And with certain tool, you can press the air to fill in to make some space inside the bottle glass. Furthermore, you can decorate the glass with certain chemical substances.

Arisan
Arisan is a term to define regular social gathering whose members contribute to and take turns at winning an aggregate sum of money. It is one way saving your money. And the one thing that make arisan is preferred than saving your money in the bank is because it is an activity that enable you to socialize with other people, especially people from your neighborhood. Some activities you do in arisan are talk gossips, trade things -usually fancy clothes, branded bags and shoes, and jewelry (especially gold and diamond), and have feast.
Task 1 - second version
My hometown, Tasikmalaya, is a beautiful city that has several beaches, three of them are Cipatujah Beach, Cikembulan Beach, and Sindangkerta Beach.
Cipatujah Beach, also called Pantai Selatan Tasikmalaya, has beautiful view of blue sea and white sand. It is a calm and safe beach where you can take on a boat and fish without any worry that your boat will be upside down by seawave.
Cikembulan Beach or Pantai Karang Tawulan is a unique beach. It is famous for its great coral reef. You can see seagulls here. And when it is coming to the middle of the month, the time when turtles lay their eggs, you will be seeing them if you are lucky enough. And there is a small island near this beach. It is called Nusa Manuk. Manuk is a Sundanese word means bird. And, yes, in this island, you can see different kinds of birds.
Sindangkerta Beach has something different than the other beaches. It has sea garden called Taman Lengsar. You can do snorkeling here. In its twenty hectare area of sea garden, you will see coral reef, different kinds of beautiful fishes, and green turtles, which is extremely endangered now.
So, are you interested in visiting my beautiful hometown?
Few Steps to Make Glass
Glass is a transparent, everyday object that can be made through series of process. To make it, we need sand, soda, and limestone, all three on equal ratio. First, the three ingredients are mixed and inserted into a furnace, then baked until they form some sort of substance. These substances are then split in two to make two kinds of glass: plate glass and bottle glass. Half of these substances are then flattened with rollers and made to harden to make plate glass. The other half are inserted into a removable mound with hollow middle that shaped like bottle. The air is inserted to make hollow place in the middle of the glass-substance. And finally, when the glass hardened, that removable mound is then removed and we have one glass bottle.
The Glass-Making Process
According to Wikipedia, glass in the common sense refers to a hard, brittle, transparent solid, such as used for windows, many bottles, or eyewear, including soda-lime glass, acrylic glass, sugar glass, isinglass (Muscovy-glass), or aluminium oxynitride. One type of glass which is now widely used either for household appliances or laboratory equipments is soda-lime glass.
The process of making soda-lime glass is quite simple. First, the raw materials such as sand, soda, and limestone, are reduced to powder, which is done in mortars or by horse mills. Sand contains silica (SiO2), which acts as the main ingredients for making glass. Silica has a very high melting point of over 2300 °C, so in order to lower the melting point and produce glass with better chemical durability, soda (common word for sodium carbonate) and lime (calcium oxide, generally obtained from limestone) are added. Those raw materials are then mixed and transported to furnace, where they are kept in a moderate heat (±1500 °C) for approximately 5 or 6 hours, being frequently stirred about during the process. After melting, homogenization and refining (removal of bubbles), the glass is formed. At this point, plate glass and container glass can be produced by two kinds of process. Plate glass for windows and similar applications is formed by putting the molten glass through rollers, making it perfectly flat, while container glass for common bottles and jars is formed by blowing and pressing methods. In making bottle glass, for instance, removable mould is used so that the bottle glass could stay in shape after the molten glass is being cooled down.
Glass Making Process
There are some steps in making these two basic forms of glass. First, the raw materials of glass which are sand, soda, and limestone are put in the furnace. After that, the furnace is heat until get suitable temperature so that the raw materials are mixed into liquid. Next step is the liquid of unreformed glass is flown in a channel. In order to get two basic forms of glass, the channel is divided into two different ways. To make a plate glass, the channel is direct on a container/ tank. After that, the liquid of unformed glass in the container is flown through a hole with the rollers that made plate form of liquid glass. Then, the plate form of liquid glass is hardened. Finally, the product of the plate glass is made. In other hand, to make a bottle glass, the channel is direct on removable mold which has bottle shape inside. Then, the liquid of unformed glass is filled into this mold. In order to get empty space in the center of the bottle, the air is pumped into this mold. After that, the liquid of glass which has bottle shape is hardened, the bottle glass is removed and the mold is refilled again. Finally, the product of the bottle glass is made. Those are some steps in making two basic forms of glass.

Among the many types of glass available in stores, there are some of them which are known as plate and bottle glass. In order to make them, several steps need to be followed. First of all, sand, soda, and limestone, which are the main ingredients for making a glass, are poured separately into a furnace through pipes. Then, after being perfectly mixed in the furnace, the ingredients are separated into two different processes, one is to produce plate glass, and the other one is to produce bottle glass. To produce a plate glass, the mixed ingredients are poured into a large container, which is connected to a roller through a hole. After the mixed ingredients reach the roller, they are shaped perfectly into a plate glass. On the other hand, the mixed ingredients need to be poured into a removable mould to produce a bottle glass. The ingredients are shaped into a bottle by the mould and after that, air is pumped into the mould in order to form an empty space within the bottle. Next, the bottle-shaped ingredients are left until they are stiff enough. Finally, the mould is removed and the bottle glass is ready to be used.

Glass Making Process
The Process of Glass Production
Glass can be found in several form, for example plate formed glass and bottle formed glass. There are some steps in making plate glass and bottle glass. First, some raw materials for glass production such as sand, soda, and limestone are mixed in a furnace which is set in certain temperature. Then the mixture is divided into two different ways, one for plate glass and the other one for bottle glass. In plate glass making process, the mixture is poured into a large tray which is connected with a roller machine. In the roller machine, the mixture is pressed to make the surface of the glass become flat. Finally the plate glass is formed. In the bottle glass making process, the mixture is poured into a removable mould which has a bottle shape on it. After that, the air is given to the mould to make a hollow space in the bottle. Next, the mould is cooled to make the mixture solid. After that, the solid mixture is removed from the mould and finally the bottle glass is formed.

How to Make Plate and Bottle Glass
Glass can be found in many forms, but only plate glass and bottle glass are talked here. There are several steps in making glass. First, the materials which are sand, soda, and limestone must be prepared. After that, the materials are put in the furnace. In the furnace, they are mixed then heated at moderate temperature first, after that the heat should be increased gradually. This requires a long heating to make a clear glass. This process produces the molten glass. Next, the molten glass is brought to separate process to make their shape. The first way, the molten glass is poured into a big container, then it is flown through rollers to make it flat. Finally, the flat glass is cut and formed well to be a plate. The second way, the molten glass is poured into a removable mould which has a bottle shape. In this step, air is flown into the mould to maintain the bottle shape of the glass. After that, the bottle glass needs to be cooled until it gets harder. Finally, the mould can be removed and the bottle is formed well.
The Glass Making Process
Glass can be formed as two main types of shape; they are bottle glass and plate glass. Some processes are needed to make both shapes from a glass. First, some materials like sand, soda and limestone are burned in a furnace. This process is going on high temperature and pressure. After that, the product of burning process is separated into two parts. In one part, that product is filled into a removable mould and then the air is pumped into it to make a hollow space in the bottle shape. Finally, the removable mould is removed and the bottle glass is ready to use. In the other part, the product of burning process is accommodated in a container and then it is siphoned into a roller machine. This roller machine is used to form a flat surface to the plate glass. Finally, the plate glass is formed.
