First, read the English article below.

Put your beans in the blender and use the pulse setting to grind them as finely as you can. You probably won't be able to achieve a finer grind than a medium to medium coarse grind, but this will be fine if you have a drip maker or a French press. Place the beans in the mortar and grind them with the pestle, as you would grind peppercorns and other spices. Keep going until you've ground them to the level you need. It will take some elbow grease, but eventually you'll have enough to make delicious coffee. If you're really desperate, place the coffee beans between two sheets of waxed paper on a sturdy surface that won't get damaged by a hammer. Use a hammer to smash the beans until you've pulverized them to a grind suitable for your coffee maker. 

Now, please write a short abstract for it in Indonesian. Abstract:
