Salam(hello),
Not pratical to try to grow figs from seeds. There have been a few discussion on this issue. It will take years to find out hat you have and whether they work. Plants started from seedss may most likely need caprification and I am not sure whether there are any special fig wasps in Indonesia that will pollinate the figs. Hence if they turn out not to be common fihs, you may have wasted all your efforts. If you have contacts in Australia, there are some good varieties. Checkout gardenweb australia or melbourne. Figs should grow very well in Indonesia.
