When talking about the cost of living, of course each region is different. Moreover, living in a small town means the cost of living will be cheaper than in a big city. Lombok is a tourist area, of course the cost of living is slightly higher. However, what is clear is that in each region in Indonesia the cost of living is definitely different.
For eastern regions such as Sulawesi, Maluku and Papua, the cost of living there is more expensive, it can be 2 to 3 times the standard of living on Java or the other islands I mentioned earlier. This is influenced by the location of the island which is far from distribution or production centers. This results in higher costs for delivering goods and services. This is the factor that causes basic commodities there to increase up to 2-3 times.
