The National examination result will be publicly enounced in next short time. Euphoria will flood for those who get success. In the other hand, It will be sorry to hear that there are some of them do not succeed in their national final examination. For those who succeed soon will think to decide; where will they be after graduating high school? Actually it will be easy to decide for those has been arranged and thought earlier but for those have not planed yet, it will be quite confusing.
Continuing study or looking for work is the primary choice among them. When they think about continuing study, they will think hard about the time and cost. How long the higher study will last? And how high is about the cost. In the same way, when they think about straightly seeking job, what skill and competence they have got is a big matter of questioning. So, doing both choices in the same time is an alternative.
Continuing study as well as seeking job is possibly done but it will be hard for them. Conventionally studying in the university needs much time to spend especially in the first year. It is true because they have to do and adapt a lot of things in their new higher school. it will be very hard to looking for job. Therefore it should come to their mind of continuing studying at higher school from their own home. As result, the available time will be more flexible for them. Then it will be very possible to seek job and get the appropriate one. This type of studying is publicly known as distance learning.
As the alternative method of studying, besides the conventional studying which students and the lecturer have to meet in the fixed time and place regularly, distance learning provides possibility to grow better. Possibly working and studying surely will create high quality graduate. Distance learning should appear as a considerable choice for them.

Example of narrative texts:1. TANGKUBAN PARAHUA long time ago in West Java, lived a woman named Dayang Sumbi. She lived alone and she was thirsting for a husband. One day when quilting, her quilt fell to the ground. Then she prayed to the gods "If a man picks up my quilt, he will be my husband. If a woman does, she will be my sister." Then, a male dog picked it up. So Dayang Sumbi got married to the dog, and called him Tumang.
Dayang Sumbi gave a birth to a son, named him Sangkuriang, but never told him who his father was. One day, Sangkuriang was hunting with Tumang in the forest. They found nothing and Sangkurian blamed the failure on Tumang and killed him. When Dayang Sumbi learned waht Sangkuriang had done, she hit Sangkuriang's head with a big spoon and expelled him.
Many years later, the wandering Sangkuriang found a house in the forest where an an old beautiful woman lived. He instantly fell in love with her. The woman was Dayang Sumbi (his mother) and she recognized hime although he did not know her. Sangkuriang forced her to marry him. She told Sangkuriang that he had to build a vast boat for their honeymoon, and in just one night. In the night, Sangkuriang called on the ghosts and forest fairies to help him. Fearing the boat would be completed, Dayang Sumbi asked another women in the nearby forest to help her. The women caused a great noise and Dayang Sumbi made flashes of light that the fairies took to be the morning light. THe fairies fled and the boat was not completed. Enraged, Sangkuriang kicked the boat. It turned upside down and turned into a mountain, called Tangkuban Parahu. The mountain stands in the north of the city of Bandung, until now.2. HOW SURABAYA WAS NAMEDOnce upon a time, on the coast of Java in an area called Tanjung Perak, there lived a variety of sea animals. They live in peace and harmony. Only an octopus, called Cumi could not get along with the other sea creatures. Cumi was very cruel. One day Cumi went to the house of a fish named Suro. He told Suro that one of the crocodiles, Boyo, would soon attack Suro. Suro and Boyo, were the best of friends and kind to each other, so of course, Suro does not believe Cumi. Cumi has many arguments with Suro, but Suro does not believe Cumi's lies.
Finally, Cumi goes to the house of Boyo. This time Cumi's lies are so believable that Boyo believes what Cumi says. He gets upset and swims in a hurry to Suro's house. Boyo is very angry and is strong and cruel. He attacks Suro and wounds him. Suro is still calm and does not fight back. But knowing that Boyo would never stop attacking him, Suro becomes brave and strong. He fight Boyo bravely until the sea turns red with their blood.
In the place where they fought was built the city called Suroboyo. Suroboyo is a Javanese word derived from Suro and Boyo. (Suro means brave and Boyo means danger. Suroboyo therefore means brave in danger. In Indonesian language Suroboyo is pronounced and spelled Surabaya.

sebuah kerucut tertutup dengan jari-jari permukaan 4cm dan tinggi 10cm berisi air setinggi 8cm.hitunglah tinggi air jika kerucut tersebut dibalik?
Untuk menjawab pertanyaan Adik, perhatikan sbb:
I. Keadaan kerucut dengan alas(permukaan di atas)
Jari-jari permukaan air (r1) = 3,2 cm ( dicari dengan perbandingan : r1:4 = 8:10 ==>
r1 = 3,2)
Volume air pada keaddn ini (V1)= π.r2 . t = π.3,22 .8
II. Keadaan kerucut terbalik, Alasnya di bawah dengan jari-jari (r) = 4 cm tinggi air =t
Volume air pada keadaan ini (V2) = π.r2 . t = π42 . t = π.16 . t
V1 = V2
π.3,22 .8 = π.16 . t
3,22 .8 = 16 . t atau t = 3,22 .8 / 16
t = 5,12
Jadi tinggi air saat kerucut terbalik adalah 5,12 cm
Dermikian semoga jelas.

tentukan ukuran tabung yang volumenya 500phi dan luasnya 250phi?
Bila diketahui volume tabung 500 Π dan Luas selimut tabung 250 Π maka :
L = 2 Π r t
250 Π = 2 Π .r .t
250 = 2.r.t
125 = r.t
t = 125/r
Volume = Π. r2. t
500 Π = Π. r2. t
500 = r2.t kemudian substitusikan t= 125/r
500 = r2. 125/r
500 = 125.r
r = 4 , kemudian substitusikan ke persamaan t = 125/r sehingga t = 125/ 4, didapat t = 31,25. Sehingga ukuran dari tabung tersebut : jari jari tabung 4 cm dan tinggi tabung 31,25 cm.
Selamat belajar ya.

BEIJING (AFP): China denied yesterday that any dispute existed between itself and Indonesia over the South China Sea’s Natuna Island, but said it was willing to hold talks with Jakarta to settle demarcation.
There is no dispute between China and Indonesia on possession of the Natuna Islands,’ said foreign ministry spokesman Chen Jian when asked about reports of growing concerns in Jakarta over Chinese interest in a gas-rich zone near the archipelago.
“We’re willing to hold talks with the Indonesian side to settle demarcation of this area.” Chen added, without elaborating. China is one of the six nations which claims all or part of the Spratly Island in the South China Sea and its interpretation of that claim includes part of the large Indonesian maritime zone of Natuna, between Borneo and the Malaysian Peninsula. United States oil giant Exxon signed a contract in November with the Indonesia state owned firm Pertamina to exploit a natural gas field, 250 kilometres northeast of Natuna, in a zone apparently claimed by China.
China has lodged no official protest over the deal. Indonesia has sent a diplomatic note to Beijing expressing its condemn the moment it found out that the latest Chinese official map showed Natuna as within dotted line of its boundary.
