First, read the English article below.

If you're trying to record in the room that has a problem with echoes, a shotgun microphone can help keep unwanted sounds out of your recording. Usually, they pick up echoes much less than standard microphones on laptops or phones do. Find shotgun microphones online or in a local electronics store. Generally, microphones pick up sound best when they're about 4 inches (10 cm) away from your mouth. If it is further away, it may start to pick up the room's echoes more. Before recording, use headphones to test how your microphone is picking up sounds. If it is picking up echoes, try moving your microphone closer to your mouth. If that doesn't work, try moving the microphone to the part of the room that echoes the least. 

Now, please write a short abstract for it in Indonesian. Abstract:
Beli mikrofon shotgun (mikrofon senapan) untuk merekam suara. Letakkan mikrofon di dekat mulut. Gunakan headphone untuk memudahkan.
