Basically, all sentences that uses "akan" turns it into a future tense sentence, since "akan" in Indonesian loosely translates to "will". For example: Indonesian: "Saya akan bermain bola nanti sore." English: "I will play football this afternoon."

well if there's a form of it, it will be Subjek + akan + kata kerja ( verb) + keterangan (time signal, etc) The "keterangan" is omitable for example: 1. Kamu akan makan besok. 2. Kita akan bertamasya ke Kebun Raya Bogor.
