How to budget‑travel from Keonjhar to Badaghagara Waterfall for a weekend?

I’m planning a quick weekend trip from Keonjhar town to Badaghagara Waterfall and want a cheap route. The waterfall is free to enter and open 24 hours, so I’m mainly looking at transport and any other nearby spots I can hit without extra cost. Are there any budget-friendly bus or cab options that would take me from Keonjhar Railway Station or Keonjhar Bus Stand to the waterfall, and can I combine a stop at Sanaghagara Waterfall (just 5 km away) or Gonasika Temple along the way?
