BKK TO DPS (Indonesia) using points -Maximize point/ or low points requirment

[NeerajNegi]

I am planning to travel from BKK to Indonesia (dps).

I am getting BKK TO DPS FOR (23~27k Singapore airline points) with taxes around 3-5k I guess ..
I am looking to transit for at least 1 day or 24 hr or break the route so now it would be. BKK TO SIN and after 4 days SIN to DPS.

Any suggestion to lower the points or how to maximize when breaking the route?
I am looking to travel BKK, SIN and DPS


Dates 28th May from BKK or before 31 May to SIN
