There are several things you will need to help you draw a sphere with this method, so be sure to have everything within reach.  Sketch pad or paper Pencil Egg cup Ruler Blending tool, cotton ball, or tissue Keep it close to the middle of the page, if possible, to give yourself enough room on all sides. Remember that one side of your sphere will have the core shadow, which is the darkest part of the sphere, where the light source cannot reach. When you lift the egg cup, you should be left with a perfect circle on your paper. Your light source will come from either the top left or the top right. The opposite side of the light source is where the core shadow will be. For a shadow that emerges from the left side of the sphere, your light source should be in the top right corner. Conversely, for a shadow that emerges from the right side of the sphere, the light source should be in the top left corner. Lightly mark a point when you reach the 1 centimeter mark. Then, draw an arrow in the corner down toward the circle, showing the direction of the light. That point is the center of the highlight, meaning that the interior of the oval will not be shaded later. This refers to the bottom edge of the circle opposite from the light source. Aim to leave about ½ centimeter between the original circle and the edge of your egg cup. The space you just created will be part of the core shadow of the sphere, the darkest part where the light source cannot reach. The shape can be described as an eclipse. Keep this in mind as you read further instructions. You should now have four eclipses, made by the egg cup, on the bottom edge of the circle opposite the light source. These eclipses should take up approximately half of the circle. They will be used for mid-tone, or gradual shading of the sphere to help give it its 3D appearance. At this point, the egg cup is too big to make smaller mid-tone outlines.  Lightly draw them in freehand form, using the shape of the small oval (i.e. the highlight spot) and expanding outward until you...

Write a summary of the previous text in Indonesian:
Siapkan bahan-bahan yang dibutuhkan. Letakkan cangkir telur secara terbalik di atas kertas. Jiplak cangkir telur untuk membuat sebuah lingkaran dengan goresan halus. Tentukan arah datangnya cahaya. Buat garis bantu yang tipis dengan penggaris dari sumber cahaya ke sebuah titik yang jaraknya 1 sentimeter di dalam lingkaran. Gambar bentuk oval kecil di sekitar titik yang barusan Anda buat di dalam lingkaran. Letakkan cangkir telur di atas lingkaran sehingga sisi yang berlawanan dari cahaya dapat terlihat. Jiplak tepi cangkir yang melengkung dari satu sisi ke sisi lain dengan goresan tipis. Ulangi langkah 7 dan 8 di atas, bergerak tiga kali semakin dekat ke tengah lingkaran. Buat beberapa garis mid-tone tambahan dengan tangan (freehand) pada sisi lingkaran yang dekat dengan sumber cahaya. Isi bulan sabit paling bawah dengan bayangan segelap mungkin. Isi sisa bulan sabit dengan bayangan yang secara bertahap semakin tipis. Campurkan warnanya dengan alat pembaur, kapas, atau tisu.
