Water Crisis in Sampang, Papua


We, from the Hydrocare Organization, are aiming to fix the water crisis problem in the villages of Sampang, Papua. We will try to fix this problem with by promoting a campaign to develop and use water filtration systems in the villages of Sampang.
There are eighty-four villages in 11 districts in Sampang, East Java that are running out of clean water. On Wednesday, 02 October, 2013, 15:48 WIB Wisnu Abdullah, Chief of Disaster Risk Management Agency (BNPB) for Sampang, said on Tuesday that the number have increased from last month; where only 59 villages reported water scarcity. Wisnu said that, “The data is in accordance to the report of each district head.”
To address the issue, Wisnu said, BNPB relies on the delivery of clean water using water tank vehicles. The severest drought is happening on northern part of the Sampang District, which includes sub-districts Omben, Karang Penang and Kedungdung. “If by October we are still on a drought, we will seek help from the provincial budget.” Usman, a resident of Kedungdung Village, said that in order to get clean water he has to purchase it from another village four kilometers away. “The price is Rp2,000 per five liters.”
As we can see here and based on our opinion, the price of water may be a little too expensive for the villagers with little income to support their families. In order to make it easier for them we, as stated before, will decrease the water problem in the villages of Sampang, Papua by developing water filtration systems. We will also hold a fund-raising program to help out our cause in buying pipes and other things needed in the water filtration systems.

Letter for the next president


 February 3, 2014
Dear,
Mr Prabowo subianto
Assalamu’alaikum Wr.Wb.

 First of all give thanks to Allah SWT because Allah still give us health and protection to make our Nation more peaceful.
Salawat and salam to our beloved prophet Muhammad SAW that has brought us from darkness into lightness.
 With honor and all respect, we are Muhammand Alariq Alghifari and Muhammad Handika Fadhlurrahman Noer, we would like to present an opinion on things that we suggest to support you as the next president of Republic Indonesia.
 As we can see nowadays Indonesia is well known as a developing country in international world, either in politics, economics, and national defense.
But, if we see the conflicts inside of our country is horrible, the biggest problem in our country are corruption and criminalities.
 The corruption rate in Indonesia is increasing every year, this corruption can make both the country and the government suffer. We personally think that the corruption here is like parasites that can ruin the governmental structure, it becomes the main obstacles for government and developing processes.
 The government have to always be cautious of corruption, law in Indonesia must be more assertive base on UUD 1945 and corruptors have to be punished as heavy as possible.
 Observing many criminalities that happened in Indonesia, that is so terrifying. From kidnapping, murdering, sexual abuse. From any criminals act there must be victims, whether from wealth or lives. Criminals act happened because of less appliances of law, and the condition of this country is on lack of employment and also economy crisis.
 Hopefully you can be much better in the future to lead this country accordance with what people wants.

Wassalamu’alaikum Wr.Wb.

11.4 Practical examples100 x $20 0


Profit: sell for more than you buy
Loss: sell for less than you buy
Discount: reduction in the price, it is usually given as a percentage
Interest: bank charges
Tax: if you buy something the price may include a additional price.
Examples
Question
 Ø A women bought an old chair for $240. She sold it for $ 300
Work out the percentages profit.
 Ø  A man bought a car for $ 15 900. He sold it for
$9500
Work out the percentages loss.
 Ø  A bottle of juice costs $ 6.50
If you buy six bottle you can get 10% discount.
Work out how much he sells them for.
Answer
 Ø  $ 300 - $ 240 = 60
60/240 x 100 % = 25 %
 Ø  15 900 – 9500 = 6400
6400/15900 x 100% = 40, 25 %
 Ø  6 x 6.5 = 39
Discount = 10/100 x 39 = 3, 9
After discount = 39 – 3, 9 = 35, 1
39-35, 1 = 3.9
00 = 800
         = 20 000 - 800 = 19.200

   price after sale = 4/100 x 19 200 = 768
                          = 19 200 + 7684% =>  4/100 x $20 000 = 800
         = 20 000 - 800 = 19.200

   price after sale = 4/100 x 19 200 = 768
                          = 19 200 + 7684% =>  4/100 x $20 000 = 800
         = 20 000 - 800 = 19.200

   price after sale = 4/100 x 19 200 = 768
                          = 19 200 + 7684% =>  4/100 x $20 000 = 800
         = 20 000 - 800 = 19.200

   price after sale = 4/100 x 19 200 = 768
                          = 19 200 + 7684% =>  4/100 x $20 000 = 800
         = 20 000 - 800 = 19.200

   price after sale = 4/100 x 19 200 = 768
               4% =>  4/100 x $20 000 = 800
         = 20 000 - 800 = 19.200

   price after sale = 4/100 x 19 200 = 768
                          = 19 200 + 768
