Launching "Laskar Pelangi" as one of Indonesian edu film

Great news for us....
A great film that is adapted from best seller book in Indonesia will be launched soon.
In september 2008, Indonesian can enjoy and feel how education can wake us up. Based on Film Director Report, it has been finishing in Bangka Belitung as the origin settings, and will be completed in Thailand.

"laskar pelangi" will be launch not only in cinema but also in "Layar Tancap" for serving areas that do not support cinema/movie theater. "Nidji" will be primary soundtract artist. Song inspired by Laskar Pelangi will be added with Netral, Gita Gutawa, Sherina, Ipang, Garasi, Float, Gugun and Bluesbugs.

plastics around us

perhatikan pada tempat minuman yang kamu jumpai di sekitarmu....
temukan kode label nomor yang ada di bawah botol plastik itu dan cocokkan apa kah kamu benar dalam memilih..

#1. PETE atau PET (polyethylene terephthalate) biasa dipakai untuk botol plastik yang jernih/transparan/tembus pandang seperti botol air mineral, botol jus, dan hampir semua botol minuman lainnya. Boto-botol dengan bahan #1 dan #2 direkomendasikan hanya untuk sekali pakai. Jangan pakai untuk air hangat apalagi panas. Buang botol yang sudah lama atau terlihat baret-baret.

#2. HDPE (high density polyethylene) biasa dipakai untuk botol susu yang berwarna putih susu. Sama seperti #1 PET, #2 juga direkomendasikan hanya untuk sekali pemakaian.

#3. V atau PVC (polyvinyl chloride) adalah plastik yang paling sulit di daur ulang. Plastik ini bisa ditemukan pada plastik pembungkus (cling wrap), dan botol-botol. Kandungan dari PVC yaitu DEHA yang terdapat pada plastik pembungkus dapat bocor dan masuk ke makanan berminyak bila dipanaskan. PVC berpotensi berbahaya untuk ginjal, hati dan berat badan.

#4. LDPE (low density polyethylene) biasa dipakai untuk tempat makanan dan botol-botol yang lembek. Barang-barang dengan kode#4 dapat di daur ulang dan baik untuk barang-barang yang memerlukan fleksibilitas tetapi kuat. Barang dengan #4 bisa dibilang tidak dapat di hancurkan tetapi tetap baik untuk tempat makanan

#5. PP (polypropylene) adalah pilihan terbaik untuk bahan plastik terutama untuk yang berhubungan dengan makanan dan minuman seperti tempat menyimpan makanan, botol minum dan terpenting botol minum untuk bayi. Karakteristik adalah biasa botol transparan yang tidak jernih atau berawan. Cari simbol ini bila membeli barang berbahan plastik

#6. PS (polystyrene) biasa dipakai sebagai bahan tempat makan styrofoam, tempat minum sekali pakai, dll. Bahan Polystyrene bisa membocorkan bahan styrine ke dalam makanan ketika makanan tersebut bersentuhan. Bahan Styrine berbahaya untuk otak dan sistem syaraf. Selain tempat makanan, styrine juga bisa didapatkan dari asap rokok, asap kendaraan dan bahan konstruksi gedung. Bahan ini harus dihindari dan banyak negara bagian di Amerika sudah melarang pemakaian tempat makanan berbahan styrofoam termasuk negara China.

#7. Other (biasanya polycarbonate) bisa didapatkan di tempat makanan dan minuman seperti botol minum olahraga. Polycarbonate bisa mengeluarkan bahan utamanya yaitu Bisphenol-A ke dalam makanan dan minuman yang berpotensi merusak sistem hormon. Hindari bahan plastik Polycarbonate

yang paling aman botol yang berkode no #4 & #5
tapi kode #7 masi diperdebat kan karena di amrik bisphenol-A aman buat makanan

botol plastik air mineral sebaiknya jangan di pakai berulang2 karena botol kode #1 cuma layak di gunakan 1x

Atomic Structure

Matter has mass and takes up space. Atoms are basic building blocks of matter, and cannot be chemically subdivided by ordinary means.
The word atom is derived from the Greek word atom which means indivisible. The Greeks concluded that matter could be broken down into particles to small to be seen. These particles were called atoms
Atoms are composed of three type of particles: protons, neutrons, and electron. Protons and neutrons are responsible for most of the atomic mass e.g in a 150 person 149 lbs, 15 oz are protons and neutrons while only 1 oz. is electrons. The mass of an electron is very small (9.108 X 10-28 grams).
Both the protons and neutrons reside in the nucleus. Protons have a postive (+) charge, neutrons have no charge --they are neutral. Electrons reside in orbitals around the nucleus. They have a negative charge (-).
It is the number of protons that determines the atomic number, e.g., H = 1. The number of protons in an element is constant (e.g., H=1, Ur=92) but neutron number may vary, so mass number (protons + neutrons) may vary.
The same element may contain varying numbers of neutrons; these forms of an element are called isotopes. The chemical properties of isotopes are the same, although the physical properties of some isotopes may be different. Some isotopes are radioactive-meaning they "radiate" energy as they decay to a more stable form, perhaps another element half-life: time required for half of the atoms of an element to decay into stable form. Another example is oxygen, with atomic number of 8 can have 8, 9, or 10 neutrons.

International Standard School

This year, some secondary high schools implement learning with international based. Especially in school with higher quality from others. They give additional treatment learning to students. They are learning in english, references in english, and many more related to english learning standard. School management give higher fees for students in it. The Students' parents hope their children can get more qualified than others, but how does it work in reality?
We have to see school competences related to resources required, infrastructures, and how prepare school?
