First, read the English article below.

Singing in a new place can be a little frightening. To get around this, go to the stage when no one else is around. Take some time to walk around and look out towards where the audience will sit. If you can, ask to test out the sound system or a microphone. You may not be able to practice at the venue, such as if you want to perform at a karaoke bar. You can, however, go to the bar and listen to other people perform. Flex not only your vocal cords, but your body as well. In addition to vocal warm-ups, such as humming notes in your vocal range, do some basic yoga poses. Raise your arms, touch your toes, dance around, and loosen up. Staying active can help you forget your worries while also preparing your body for singing.  Any good stretch can help, but don’t go overboard and hurt yourself. To get out excess energy and adrenaline, do some jumping jacks or air punches.  Always loosen your vocal cords before singing. Try choosing a word like “Re” and singing it up and down your vocal range. An important part of building confidence is mastering your posture while singing. Plant your feet firmly on the ground, standing straight. Lower your shoulders, keeping your head level with your audience. This keeps your airways free, allowing you to project your voice. Even the act of standing in a position like this can cause you to feel a little more confident. In addition, your singing voice improves, leading to even more confidence. Slowly breathe in and breathe out. Let the air go all the way down to the bottom of your lungs. You will need all that air when projecting your voice. You can also do this while singing. Focus on taking a deep breath, then using the air to radiate your voice out from the center of your chest.  Deep breathing is calming. By breathing away any nervousness, you can relax, focus on your voice, and gain confidence. To further calm your nerves and help you focus on your performance, spend a few minutes doing a mindful meditation. You can find guided meditations here:... 

Now, please write a short abstract for it in Indonesian. Abstract:
Sisihkan waktu untuk datang ke tempat menyanyi sebelum jadwal pertunjukan. Lakukan peregangan otot untuk merilekskan tubuh sebelum tampil di pertunjukan. Berdirilah tegak sambil merilekskan bahu. Bernapaslah dalam-dalam Jangan berhenti berlatih jika Anda melakukan kesalahan saat menyanyi. Berfokuslah pada lagu, bukan pada audiens. Berusahalah mengatasi demam panggung.
