On Thursday, June 19, 2025, the Doctoral Program in Economics with a concentration in Development Economics (Islamic economics and finance) held a closed session with the promovenda Sisca Damayanti, in this session the promovenda was declared to have passed. The research conducted for her dissertation was themed on Halal Purchasing Behavior. Hopefully this session can be a stepping stone for the next session, namely the open session. Once again, congratulations and success to promovenda Sisca Damayanti for her achievements.
