Harapan Bunda
Ku lukis indah sayap putri kecilku
Kan terukir seribu cerita yang bahagia
Tuk mampu terbang ke langit biru
Temani malaikat yang tersipu malu
Jemari telah menyapa
Menari indah dan tertawa lepas
Pesona ia bersimpul irama
Di taman angkasa Sang Kuasa
Wajah kecil yang sangat mungil
Selalu ku manjakan dan ku timang
Hanya sanggup terpukau
Tanpa harus tinggal disana
Inikah pintaku....
Ku sentuh itu dengan lembut
Ku rangkai cita-citaku untuk anak ku

Three other brand new song “Dilema”, “Jangan Bilang Pacarku” and “ Semua Orang Berhak Mendapat Rasa Bahagia”, gives supporting nuances to the movie flow as GIGI composed them by imagining how the scenes would like look based on the screenplay.
When Hanung Bramantyo, the director, and Dewa Budjana of GIGI chated, Budjana expressed his interest in making soundtrack album.

Armand Maulana (vocalist), I Gede Dewa Budjana (guitarist), Thomas Ramdhan (Bass player) , and Gusti Erhandy (Drum-stand-in player for Budhi haryono) put a lot of effort to this album. As a result, they’ve created perfect blend of movie and songs that makes BROWNIES tastier.
It’s always fun to have a piece of Brownies in your mouth. But having it in your stereo set is more entertaining. No movie is perfect without musical score and OST of Brownies proved it excellent.

Is Smoking Good For Us?
Before we smoke, it is better to look at the fact of smoking effects, not only for smokers but also for non smokers. About 50 thousands people die every year in Britain as the direct result of smoking. This is the seven times as many as deaths in road accidents. Nearly a quarter of smokers die because of diseases caused by smoking.
Ninety percent of lung cancers are caused by smoking. If we smoke five cigarettes a day, we are six times more likely to die of lung cancer than a non- smoker. If we smoke twenty cigarettes a day, the risk is nineteen times greater. Ninety five percent of people who suffer from bronchitis are people who smoke. Smokers are two and half times more likely to die of heart disease than non- smokers.
Additionally, children of smokers are more likely to develop bronchitis and pneumonia. In one hour in a smoky room, a non-smoker breathes as much as substance causing cancer as if he had smoked fifteen cigarettes.
Smoking is really good for tobacco companies because they do make much money from smoking habit. Smoking, however, is not good for everybody else.

“Bisa Saja” is choosen as the first single of the album and theme song of BROWNIES, since the lyric reflects the story in the movie. Budjana of GIGI demonstrates his skills in playing acoustic guitar in “ Cinta Terakhir “. Three other brand new song “Dilema”, “Jangan Bilang Pacarku” and “ Semua Orang Berhak Mendapat Rasa Bahagia”, gives supporting nuances to the movie flow as GIGI composed them by imagining how the scenes would like look based on the screenplay.
When Hanung Bramantyo, the director, and Dewa Budjana of GIGI chated, Budjana expressed his interest in making soundtrack album. Then, he recommended a few of GIGI songs, which the producer accepted because of the chemistry they created with the movie. Since GIGI can provide a variety of colors to add all kinds of musical nuances to enrich the movie, the producer deemed it unnecessary to find other musicians to complete OST of BROWNIES. Armand Maulana (vocalist), I Gede Dewa Budjana (guitarist), Thomas Ramdhan (Bass player) , and Gusti Erhandy (Drum-stand-in player for Budhi haryono) put a lot of effort to this album. As a result, they’ve created perfect blend of movie and songs that makes BROWNIES tastier.
It’s always fun to have a piece of Brownies in your mouth. But having it in your stereo set is more entertaining. No movie is perfect without musical score and OST of Brownies proved it excellent.

Is Smoking Good For Us?
Before we smoke, it is better to look at the fact of smoking effects, not only for smokers but also for non smokers. About 50 thousands people die every year in Britain as the direct result of smoking. This is the seven times as many as deaths in road accidents. Nearly a quarter of smokers die because of diseases caused by smoking.
Ninety percent of lung cancers are caused by smoking. If we smoke five cigarettes a day, we are six times more likely to die of lung cancer than a non- smoker. If we smoke twenty cigarettes a day, the risk is nineteen times greater. Ninety five percent of people who suffer from bronchitis are people who smoke. Smokers are two and half times more likely to die of heart disease than non- smokers.
Additionally, children of smokers are more likely to develop bronchitis and pneumonia. In one hour in a smoky room, a non-smoker breathes as much as substance causing cancer as if he had smoked fifteen cigarettes.
Smoking is really good for tobacco companies because they do make much money from smoking habit. Smoking, however, is not good for everybody else.
29. What is the text about?

Cerpen tata tertib
Kedisiplinan dan ketertiban di lingkungan sekolah memang sangatlah penting, karena hal ini sering kali terjadi pelanggaran kedisiplinan dan ketertiban yang dilakukan para siswa. Oleh sebab itu kedisiplinan dan ketertiban perlu kita atur dalam sebuah tatanan yang biasa kita sebut dengan tata tertib sekolah. Adapun dibuatnya tata tertib tersebut memiliki dua tujuan yaitu tujuan khusus dan juga tujuan umum. Secara khusus memiliki tujuan supaya kepala sekolah bisa menciptakan suasana yang kondusif bagi semua warga sekolah, supaya para guru bisa melaksanakan belajar mengajar dengan optimal dan supaya tercipta kerja sama di antara para orang tua dengan sekolah dalam mengemban tugas pendidikan. Sedangkan tujuan secara umumnya yaitu agar terlaksananya kurikulum secara baik serta bisa menunjang peningkatan mutu pendidikan di dalam sekolah.
Untuk bisa menegakkan kedisiplinan di dalam lingkungan sekolah memang diperlukan tunjangan peraturan dengan ketentuan-ketentuan yang sifatnya mengikat setiap komponen baik itu guru, siswa maupun kepala sekolah guna mencapai tujuan yang sudah ditetapkan berupa tata tertib sekolah. Sementara untuk menegakkan tata tertib tersebut haruslah dimulai dari kelompok sekolah itu sendiri, dengan begitu maka sekolah bisa menjadi tempat dan sarana belajar dengan manajerial yang baik. Selain itu disiplin memang merupakan hal penting yang harus ditanamkan kepada anak didik kita di sekolah sedini mungkin, dengan tata tertib yang diterapkan setiap hari tersebut maka bisa membuat para siswa menjadi terbiasa untuk bersikap disiplin dan tertib. Kelas pun juga harus memiliki tata tertib sendiri yang harus dicontohkan dan dijelaskan kepada siswa agar dilaksanakan terus menerus. Beberapa taat tertib tersebut antara lain seperti :

Kelas pun juga harus memiliki tata tertib sendiri yang harus dicontohkan dan dijelaskan kepada siswa agar dilaksanakan terus menerus. Beberapa taat tertib tersebut antara lain seperti :
Masuk sekolah
- - Siswa diharuskan datang tepat waktu
- - Tas dan alat tulis ditaruh di laci meja, setelah itu keluar kelas
- - Bagi siswa yang mendapat giliran piket harus datang lebih awal
- - Bagi siswa yang tidak masuk harus membuat surat izin tertulis
- - Guru tidak boleh terlambat datang
- - Doa dipimpin ketua kelas
- -Memberikan salam pada guru
- - Guru melakukan absensi
- - Tidak boleh bercanda atau melakukan kegiatan lainnya ketika proses belajar
- - Siswa tidak boleh keluar kelas tanpa izin
- - Guru dilarang meninggalkan kelas saat pelajaran berlangsung
Memberikan dukungan supaya terciptanya sikap ataupun perilaku yang tidak menyimpang
Membantu para siswa untuk menyesuaikan diri dan memahami diri dengan tuntutan lingkungan
Sebuah lingkungan sekolah yang tertib dapat memberikan gambaran lingkungan siswa yang gigih giat, penuh perhatian, serius dan kompetitif dalam pembelajarannya. Sehingga dengan adanya tata tertib sekolah tersebut diharapkan bisa memberikan andil besar terhadap lahirnya siswa yang berhasil serta berkepribadian yang unggul.

b) Tentukan bayangan dari
titik A (5, 10) oleh translasi
c) Tentukan bayangan dari titik A (1, 2) oleh translasi T = (1, 2) dilanjutkan oleh translasi U = (3, 4)
Pembahasan Bayangan dari titik A oleh suatu transformasi namakan A’ Dua model yang biasa dipakai sebagai berikut:
Hasilnya akan sama saja, hanya sedikit beda cara penulisan, sehingga: a) Bayangan dari titik A (2, 3) oleh translasi T = (7, 8)

Soal No. 2
Disediakan suatu persamaan garis lurus
Y = 3x + 5
Tentukan persamaan garis lurus yang dihasilkan oleh translasi T = (2, 1)
Pembahasan
Ada beberapa cara diantaranya:
Cara pertama:
Posisi titik (x, y) oleh translasi T = (2, 1) adalah:
x’ = x + 2 → x = x’ – 2
y’ = y + 1 → y = y’ – 1
Masukkan nilai x dan y yang baru ke persamaan asal
y = 3x + 5
(y’ – 1 ) = 3(x’ – 2) + 5
Tinggal selesaikan, ubah lambang y’ dan x’ ke y dan x lagi:
y – 1 = 3x – 6 + 5
y = 3x – 6 + 5 + 1
y = 3x
Cara kedua:
Ambil dua buah titik dari persamaan y = 3x + 5
Misal:
Titik A, untuk x = 0 → y = 5 dapat titik A (0, 5)
Titik B, untuk Y = 0 → x = – 5 /3 dapat titik B (– 5/3 , 0)
Translasikan Titik A dan B dengan T = (2,1)
A’ (0 + 2, 5 +1) = A’ (2, 6)
B’ (-5/3 + 2, 0 + 1) = A’ (1/3, 1)
Buat persamaan garis yang melalui kedua titik itu:
Cara ketiga Dengan rumus yang sudah jadi atau rumus cepat:
ax + by = c
Translasi T (p, q)
Hasil :
ax + by = c + ap + bq
Rumus ini untuk bentuk seperti soal di atas, jangan terapkan pada bentuk-bentuk yang lain, nanti salah. y = 3x + 5 atau 3x − y = − 5 oleh T = (2,1) Hasil translasinya adalah: 3x − y = − 5 + (3)(2) + (− 1)(1) 3x − y = − 5 + 6 − 1 3x − y = 0 atau y = 3x Soal No. 3 Titik A memiliki koordinat (3, 5).
