Hello, ladies and gentlemen

Are you know ? if most people in Indonesian die because drugs. Do you know if most of them is tenagers? A drugs is so dangerous now. According to The National Narcotics Agency (BNN) in a press release, explains  in 2010, an estimated 316,000 until  335,000 lives of drug users. We can’t imagine how Indonesian if most of tenagers is used a drugs certainly make into concern for we are.

For me a drugs abuse is a big disaster for the nation future for me and for we all, because a  quality of a tenagers is determine  a quality of the nations. If  a tenager is broken the nations is broken too. Now I will invite all of you to discus of the impact of the drugs abuse.

First, form the healty, a drugs abuse make the body a used be risk to infected so much desease one of all is HIV. We are know how dangerous this desease and until now we don’t found the medicine for this desease. This desease is because from needle that infected. A used drugs usually use a nedle by turns with their friend. From here a HIV desease is infect.

Second, from the social, a used drugs abuse will be isolated in society. The family will be a big shame because have family  members that use drugs. A used will be lonely because the people afraid to near a used
Third, from the education, the used will be lost learning apportunities may be expelled from school or college because must be join rehabilitation or in jail because doing a criminal.

The last, drugs abuse can be prevented including stay away from the people who use drugs, think about the bad effect that makes you have a very strong reason not to do so (ex : money runs out, work neglected, automatically become a liar, and of course your time will be wasted), think of the pleasure that is very satisfying when this life without drugs and follow the activities.

Start with yourself...
If not now when again...!!!
Remember, your future is only yourself that can change your future for the better. So, do not ever take risks to try things that can damage yourself.
Say no to drugs…!!!

Tahukah anda siapa yang penemu bahan kertas pertama kali?
 Penemunya bernama Ts’ai Lun, seorang pegawai negeri pada pengadilan kerajaan yang kemudian diangkat menjadi sekretaris kerajaan pada masa Dinasti Han. Dengan jabatannya tersebut, pekerjaan Ts’ai Lun selalu berhubungan dengan urusan tulis menulis. 

Pada masa itu, umumnya warga Cina menggunakan pelepah bambu dan bahan sutra  untuk media tulisnya. Buku dari bambu tersebut sangat berat, sehingga sulit dibawah ke mana-mana, sedangkan buku berbahan sutra harganya sangat mahal.
Inilah hal yang mendasari Ts’ai Lun untuk berupaya mencari alternatif bahan untuk media tulis menulis yang murah dan mudah dibawa ke mana-mana. Pada tahun 105 Masehi, Ts’ai Lun mempersembahkan contoh kertas kepada Kaisar Ho Ti (Catatan Tiongkok tentang penemuan Ts’ai Lun ini terdapat dalam penulisan sejarah resmi dinasti Han).
Penemuan Ts’ai Lun ini membuat perubahan radikal dan bersejarah dalam hal tulis menulis di negeri Cina. Penemuan ini segera berkembang dan tersebar ke Arab dan Eropa, hingga ke seluruh dunia. Penemuan penting yang menjadi sebuah warisan dunia yang sangat bermanfaat bagi kehidupan di dunia.                     
Gimana gan ?                                                                                                               Bayangkan bila tidak ada kertas mau tulis dimana kita ?
