First, read the English article below.

Make sure the sandpaper is very wet and that your work surface is hard and durable. To wet your sandpaper, dip it into a container of clean water, then sprinkle some additional water on top of the paper after you lay it down. You can also use emery cloth if you don’t have access to wet sandpaper. You can buy a multi-pack of emery cloth from most home improvement or hardware stores. Hold the glass in your dominant hand and keep the sandpaper steady with your non-dominant hand. Be sure to wear safety gloves and goggles for maximum safety.  You can typically buy safety gloves and goggles at any home improvement store that also sells sandpaper. If your glass has multiple sharp edges, hold it so that none of the edges can cut your palm. If it’s impossible to hold your glass this way, consider smoothing the edges using a different method. Apply gentle downward pressure onto the top of the glass so that you drive it slightly into the sandpaper. Rotate the piece of glass every 2-3 circles in order to keep the sanding more uniform.  If you refrain from rotating your piece of glass, you may end up sanding one side much more than the others, leaving a noticeably uneven finish. Aim to do this for at least around 5 minutes to ensure that the glass edge is adequately smoothed. After you finish sanding the “front” of the glass edge, pick up the sandpaper and dip it into the water again to dampen it. Then, take the sandpaper in your dominant hand and place it over the glass edge so that your thumb and middle finger are over the corners of the edge. Finally, rub the sandpaper back and forth to sand down these sharp corners until they’re smooth. Keep the sandpaper wet as you do this. You may need to continually dip it into the water to keep it adequately moist. Sand down the edges with 150-grit, 220-grit, 320-grit, then finally 400-grit sandpaper to make your glass even smoother. Then, use 1000-grit and 2000-grit sandpaper to polish the edge to perfection. Wipe the edge of the glass with a clean damp cloth once you’ve finished... 

Now, please write a short abstract for it in Indonesian. Abstract:
Basahi ampelas yang memiliki grit (tingkat kekasaran) 80 dan hamparkan di atas permukaan kerja. Tempatkan bagian tepi potongan kaca di atas amplas. Gerakkan gelas dengan gerakan melingkar selama sekitar 5 menit untuk menghaluskan bagian tepinya. Ampelas sudut bagian dalam dan luar tepi kaca menggunakan tangan. Ulangi proses ini menggunakan ampelas yang lebih halus.
