Eventually you will come across some glyphs. These items are a common drop on enemies, but are most commonly found in “Heavy Sacks” and treasure chests. They can instantly be used to enchant your weapons. In order to get to your inventory, press the Start button, hit the A button under “Inventory,” and select “Weapons” to see all the gear you have stored in it. A screen will pop up with a couple of different options. Do this by hitting the A button while the word “enchant” is selected. A new screen will show all the glyphs that can currently be applied to  your weapon. Scroll through your glyphs until you find the one you want to use. When you find the glyph you want to enchant your weapon with, hit the A button. This will enchant your weapon. Enjoy using your newly enchanted weapon when you are playing ESO. Note that you can only add one enchant to a weapon.

TL;DR in Indonesian:
Kalahkan musuh untuk mendapatkan barang. Periksa Inventory (kantong yang berisi barang dan perlengkapan) untuk menemukan senjata yang ingin diberikan enchantment. Tekan tombol segitiga (untuk PS4) atau tombol "Y" (untuk Xbox One) untuk membuka opsi tambahan untuk senjata yang disoroti. Pilih opsi “Enchant” pada menu. Lakukan enchanting pada senjata.
