Hay is not a good bedding anyway--it's not absorbent. It only need to be provided (in unlimited amounts) as food.

Zeolite could be dangerous to your pigs, and it sounds messy as well. Don't use it. The wood shavings could also be harmful. Don't use them. Newspaper is not absorbent, but it is safe. I would not use it, but if you really want to put it in a litter box and change it at least daily, you can.

I'm sure you can find fleece in Indonesia--it's a very common material for blankets. It should not be hard to find. As already mentioned, anything that is 100% polyester should work.

The towels are absorbent, which is why they should be under fleece, not used alone. I would use only fleece on top and towels on the bottom--no other bedding. There is no point in using the wood shavings, zeolite, and newspaper.
