Assalamu'alaikum wr.wb.
Yang terhormat kepala desa Kutaliman , Bapak - bapak dan Ibu - ibu yang saya hormati, serta pemuda pemudi desa kutaliman yang saya hormati pula.
Sebelumnya marilah kita panjatkan puji syukur kehadirat Alloh SWT. yang telah melimpah kan rahmat dan hidayah Nya sehingga kita dapat berkumpul dalam peringatan HARI BUMI SEDUNIA.
Sholawat serta salam semoga tetap tercurahkan kepada junjungan kita Nabi Agung Muhammad SAW. yang telah membawa kita ke zaman yang cerah ini.
Saya berdiri disini akan menyampaikan sepatah kata tentang menaik nya suhu akhir - akhir ini .
Hadirin sekalian.
Kita ketahui bahwa akhir - akhir ini suhu disekitar kita menaik .Hari - hari semakin panas , dan cuaca makin tidak menentu . Itulah beberapa fakta akibat adanya pemanasan global.
Hadirin yang saya hormati,
pengertian dari pemanasan global itu sendiri adalah menaiknya suhu di atmosfer bumi yang diakibatkan karena panas yang dipancarkan oleh Matahari terperangkap oleh atmosfer yang diakibatkan menipisnya lapisan ozon. Kita merasakan dampaknya, tanah yang mulai kekurangan air dan musim kemarau makin panjang. Yang mengakibatkan menurunnya hasil panen di desa kita.
Dengan adanya dampak ini, sepatutnya kita mulai sadar betapa pentingnya menjaga kelestarian. Salah satu penyebab menipisnya lapisan ozon adalah karena berkurangnya pohon sebagai penyerap oksigen.
Hadirin yang saya hormati.
Sekali lagi mari kita lestarikan bumi ini dan jaga energi yang ada.
sekian sambutan dari saya, kurang lebihnya saya mohon maaf .
Wassalamualaikum wr.wb.

Menginstall Sistem Operasi Komputer Windows XP pada VirtualBox
Oracle VM Virtualbox merupakan perangkat lunak virtualisasi yang dapat mengoprasikan sistem oprasi komputer bayangan (tambahan) di dalam sistem operasi utama. Sebagai contoh, kita mempunyai sebuah komputer yang di dalamnya terdapat sistem operasi Windows 7. Di sini kita akan mengsimulasikan pemasangan sistem operasi Windos XP maka terlebih dahulu kita menginstall virtualisasinya dan disini kita menggunakan VirtualBox sebagai media virtualisasinya agar tidak menggangu sistem operasi utamanya . Sebenarnya selain dari VirtualBox itu sendiri masih ada media virtualisasi yang lain seperti VMware dan Microsoft Virtual PC. Sistem Operasi yang dapat dijalankan antara lain Linux, MAC OS X, Windows XP, Windows Vista, Windows 7, Windows 8, Solaris dan OpenSolaris.
Simulasi Menginstall Sistem Operasi Windows XP
Kita mulai untuk simulasi menginstall windows XP di VirtualBox yah,....
Aku yakin mudah loh,...
Tapi jangan lupa siapkan master Windows XPnya, dan pastikan Oracel VM VirtualBoxnya udah terinstall yah,...
1. Setelah kita siap dengan Oracel VM VirtualBoxnya, selannjutnya pilih New
2. Nah hasilnya tuh seperti gambar di bawah ini :
Isikan nama yang mudah pada form name. Terus klik Next.
3. Kemudian tentukan memori yang akan digunakan, dan klik Next.
4. Kemudian pilih Create a virtual hard drive now untuk menambahkan virtual hard drivenya, dan kemudian klik Creat.
5. Memilih VDI dan klik Next.
6. Memilih pilihan Dinamically allocated dan kemudian klik Next
7. Pada
kolom nama seperti gambar di bawah ini tuliskan nama anda dan menentukan size virtual hard drivenya , dan klik create.
8. Nah klo sudah hasilnya tuh kaya gini nih :
9. Selanjutnya klik icon start untuk memulai menginstall, selanjutnya klik OK dan pilih Master sistem Operasi Windows XP nya ,... Dan klik Start dech,...
10. Kalau udah hasilnya kan kayak gini nich,...
Tinggal klik Enter kalau mau diterusin,... dan ikutin aja terus kalau disuruh klik f8 ataupun Next sampai kayak gini,... Ini artinya sedang install secara otomatis,.
11. Dan selanjutnya akan restart secara otomatis.
12. Setelah restart masih ada selanjutnya ya,... klick Next aja dan kalau disuruh isi formnya isi aja data sesuai yang diinginkan .
13. Owh iya kalau udah sampe sini masukan Product Keynya ya,...
Product Keynya bisa di unduh disini nih Product Key Windows XP
Product Keynya bisa di unduh disini nih Product Key Windows XP
14. Selanjutnya tinggal Next dan isi formnya sesuai yang diinginkan deh,...
Nah Kalau udah tuh akan restart lagi dan windows XP udah terinstall,..
Nah mudahkan caranya silahkan mencoba,...
Kalau butuh Master VM VirtualBoxnya bisa Download di sini.

Lighting:
Hard and Soft Light
The art of cinematography is the art of lighting
and making that light tell the story.
-Stephen H. Burum, ASC
(Apocalypse Now, Carlito's Way, Mission Impossible,
Body Double, Life or Something Like It,etc.).
Lighting can emphasize important details or hide them. It can flatter a subject by bringing out positive attributes, and it can de-emphasize or hide less attractive attributes. Lighting can even impart a sinister and hostile look. It all depends on how you choose to use the concepts we'll be covering in the next few modules.
Television is based on the medium of light; in fact, without light there could be no video. Just as sound must be skillfully controlled in audio production, light must be expertly controlled in television.
As video—especially HDTV—has begun to emulate the more artistic dimensions of film, there has been a greater emphasis on creative lighting. But, before you can successfully control light, you need to understand and control its three basic characteristics:
• coherence (quality)
• color temperature
• intensity
In this module we'll cover the first of these —
Light Coherence
Coherence, often called quality, is the hardness or softness of light. Light quality is probably the least understood and the most neglected of the three variables.
In the photos above the objects are exactly the same. Two of the variables of light are also exactly the same: intensity and color temperature. The only difference is the third variable: the coherence of the light. The first photo was shot with soft light, the second with a hard light source. (In Module 35, "Altering Appearances," we'll look at additional factors that can affect the appearance of subject matter.)
Hard Light
Light that is transmitted directly from a small point source results in relatively coherent (parallel) rays. This gives the light a hard, crisp, sharply defined appearance. The light from a clear, unfrosted light bulb, a focused spotlight, or the noonday sun in a clear sky, all represent hard light sources.
Hard light casts a sharp, clearly defined shadow. When hard light is used to illuminate a face, imperfections in the skin stand out. The result is less than flattering. But in other applications, such as bringing out the texture in leather, or the engraving on a piece of jewelry, this can be an advantage.
Note in the photo on the left how the writing stands out. Also note the clearly defined shadow of the flower at the bottom of the photo. Compare this photo with the one in the section below (with soft light) where the letters are hard to read and the shadow of the flower has all but disappeared.
Several types of lighting instruments are used in TV to create hard light, including the beam-spot projector and the ellipsoidal spotlight.
Soft Light
Soft (diffused) light has the opposite effect. As shown in the photo on the left below, soft light tends to hide surface irregularities and detail.
Spun-glass diffusers (above) are used over the front of lights to soften and diffuse their beams. Note resulting photo on the left. At the same time, diffusers also reduce the intensity of light.
Soft light sources are used in production to create a broad, even area of light. In the field, videographers often rely on umbrella reflectors (on the right, below) to create a soft lighting effect. As you can see, this is simply a light bounced off the inside of a silver or white, umbrella-like reflector. The illustration below on the left shows a much heavier soft light that is commonly hung from the grid in studios.
Because soft light tends to hide lines, wrinkles and blemishes, it's desirable in doing glamour work. The photo of the model on the left was shot with soft light.
A soft light source placed close to the camera minimizes surface detail. The effect is commonly referred to as flat lighting.
Although it has certain applications, especially in extreme close-ups of objects where shadows would obscure important details, flat lighting leaves subject matter somewhat "dimensionless." When used over a large area, it can impart an arid and sterile-looking appearance.
Ultra-Soft Lighting
There are a few occasions when ultra-soft lighting is necessary to keep video equipment from exceeding its brightness or contrast range limitations and compressing (losing) important detail.
Compare the picture on the left with the one below. Note that when standard lighting is used (on the left) the reflections from the shinny objects drive down the video levels in the darker areas. (Recall the illustration of video spikes in Module 16.) As a result, important detail is lost.
The same problems are encountered when you photograph shiny metallic objects such as jewelry and silverware.
These problems can be fixed (as seen on the left) by using an extremely soft lighting setup—in this case the lighting tent shown below.
To create this ultra soft lighting the subject matter was surrounded by a white sheet, leaving only a small opening for the camera lens. Three lights placed at different angles lit the sides of the sheet.
