Water Cleaning Project

FAPIPS Water Cleaning Organization from Al-Taqwa College Indonesia would like to introduce our plan

Program: Water Cleaning

Name of organization: FAPIPS water cleaning

Slogan: Air bersih, kita senang.

Aim: We want to help the people who live nearby the Citarum river get clean water.

Location: Citarum River, Bekasi, Indonesia

How to reach there: Voluntary transportation with the help of google map.

Reason: The people of Citarum are lacking of clean water.

Problem: Citarum river is covered in rubbish so that no clean water can be obtain.

Solution: Clean the river from the rubbish.

Steps:
1. Persuade the society to cooperate by stop littering.
2. Pick up all the rubbish in the river in order to clean it.
3. Cooperate with a company in Citeureup to recycle the rubbish.
4. Get a sponsor.
5. Cooperate with the government to support our program.

((FAPIPS stands for Fatimah, Angela, Putri, Indah, Prstina, Shoffa. These are the main members.)

How to make a better Indonesia?

Assalamualaikum wr. wb.

First of all, we would like to introduce ourselves. We are students from an Islamic International School located in Hambalang, Bogor. We decided to make this letter for you to make sure that you'll do a great job if you are elected to become the next President of Indonesia. This is a pleasure for us. A big appreciation for you if you are interested to read, Sir. We are only normal teenagers that want to make this country even better in the future. Indonesia is a very beautiful country to be visited by tourists from different parts of the world if we have a good government system. It means that we have to be careful to select for the next President to take care of our beloved country. We wrote this specially for you, because we believe that you could do a great improvement on managing the system.

Let us outline some topics that we would like to "discuss" here:
1. Disaster,
2. Poverty, and
3. Cleanliness

The topics above might be not really important but those are really have a big impact. The things that we will explain after this are based on our thoughts and what we feel of being apart of citizen of Indonesia.

1. Disaster
This one is happening a lot now. Mount Kelud just exploded a week ago and thunderstorm happened during the process. Many people died because of the poisonous ashes which came out from the mouth of the mountain. The ashes are spreading all over the city even it reaches our capital city, Jakarta. Maybe not much but still. On this case, the government should give more attention to the people who live around the area. Give them more daily life supplies (the basic ones: healthy food and fresh mineral water) to survive and a suitable place to save themselves. Not like an empty building and just let them lay down there. What if there is a pregnant woman? A sick child? Who wants to give medicines and take care of them in that kind of crowded place? Diseases are easily to spread and we don't want the other people become sick too just because of one person.

2. Poverty
Everyday many people are trying to live their life to the fullest. They are working so hard to get the best way to survive. With a simple "house" which made out of woods or bamboos, they won't give up. People who just graduated from universities and seeking for jobs, successful people, "unsuccessful" ones; there are many kind of people in this one country. We still have to remember, as apart of successful people, that there are still those "unlucky" society. Living an unhealthy life near dirty rivers or any kind of unsuitable places. They are keep on trying to find out how to make their life better. No additional "facilities" from the government which make them even worst.They need something to change their lifestyle. How can a society live in those kind of conditions? Unskilled, not having a proper job then they still have children, parents who they need to take care and of course it spends a lot of money just to buy a food. Where is the government that CARE of this society? So far, it has been the same. We don't see any changes of this issue. The other citizens are helping them, yes, but we need the government to help us too. How can this country be developed if the poverty keeps on increasing each year?

3. Environment
No wonder there are many diseases and viruses spread in surrounded areas. Big cities or small villages. Pollution, rubbish everywhere, well who isn't sick of seeing and feeling this everyday? We do have many trees, but they wont help us that much if we kept on cutting them illegally and use the land to build large and tall buildings. We're still wondering of something, why do people keep on throwing rubbish not in the right place? They knew it will cause flood and other environment impacts. Well this is actually based on individuals awareness. Look at every time we walk past a street, there must be rubbish at the edges. Who doesn't feel digusted seeing a bunch of mixed rubbish? Do something to make this country as beautiful as other developed countries. Make the tourists feel comfortable while they are travelling around; seeking for good places to be visited so they will be impressed and we believe it will make them missing how lovely our environment is. By this, we will be prouder as an Indonesian.


I hope our opinions and suggestions are acceptable and useful for other people. We apologise for any mistakes written because we are humans and we make mistakes. Thats all from us.

Wassalamualaikum wr. wb.

12.5 Drawing a locus (MATH)

A locus is a set of points that follow a given rule. The plural of locus is loci.
You need a ruler and compasses to draw loci accurately.

12.4 Enlarging shapes (MATH)

When you enlarge a shape, all the lengths of the shape increase in the same proportion.
This is called the scale factor. All the angles in the shape stay the same size.

When you describe an enlargement you must give:

  • the scale factor of the enlargement
  • the position on the centre of enlargement.

12.3 Transforming shape (MATH)

You can use combination of reflections, translations and rotations to transform a shape.
You can also describe the transformation that maps an object onto its image.

To describe a reflection you must give:

  • the equation of the mirror line.
To describe a translation you must give:
  • the column vector.
To describe a rotation you must give:
  • the centre number
  • the number of degrees of the rotation (or fraction of a whole turn)
  • the direction of the rotation (clockwise or anticlockwise).


12.2 Solving Transformation Problems (MATH)

You already know that a shape can be transformed by a reflection, rotation or translation. When a shape undergoes any of these three transformation it only changes its position. Its shape and size stay the same. Under these three transformations, an object and its image are always congruent.
When you reflect a shape on a coordinate grid you need to know the
equation of the mirror line.
All vertical lines are parallel to the y-axis and have the equation x = 'a number'.
All horizontal lines are parallel to the x-axis and have the equation y = 'a number'.
Some examples are shown on the grid on the right.
When you rotate a shape on a coordinate grid you need to know the
coordinate of the centre of rotation, and the size and direction of the turn.
When you translate a shape on a coordinate grid, you can describe its movement with a column vector.

This is an example of a column vector : (4,5)

The left number state how many units to move the shape right (positive number) or left (negative number). The right number states how many units to move the shape up (positive number) or down (negative number).

For example:  (4,5)  means 'move the shape 4 units right and 5 units up'
                      (-2,-3)  means 'move the shape 2 units left and 3 units down'.


You can use any of these three transformation to solve all sorts of problems.

12.1 Tessellating shapes (MATH)


A tessellation is a pattern made of identical shapes. You can make your own tessellation by fitting copies of a shape together, without gaps or overlaps. You say the shape tessellates, or is a tessellating shape.

Here are some examples of shapes that tessellate with themselves:


Here are the examples of shapes that do not tessellate with themselves. There are gaps between the shapes : 

 




When you make a tessellation are made by repeating a shape and using half-turn rotations of the same shape. For examples, this triangleand a half-turn rotation of the same trianglefit together exactly to make a tessellation like this. 


In any tessellation, the sum of the angles at the point where the vertices of the shape is 360°. Look closely at three of the tessellations above.







work this out!

1. explain how you know that a regular hexagon will tessellate. show all your working and include diagram in your explanation.
