After graduating from Airlangga, Thungari began to run PT Pancaran Berkat Mulia, a logistics and construction company which operates cargo ships between
Makassar and
Tahuna, capital of the
Sangihe Islands Regency. The company heavily utilized the
Sea Toll Program, which according to Thungari subsidized around half of the shipping cost to Tahuna. In 2019, Thungari ran for a seat in Sangihe Islands'
Regional House of Representatives (DPRD Sangihe) as a
NasDem Party member, securing a seat after winning 2,985 votes, the most of the 25 elected members. He became the deputy speaker in the DPRD. He was reelected in
2024, again winning the most votes (3,012). The pair secured 38,385 votes (46.6%) in the four-way race and won the election. Thungari and Bulahari were sworn in on 20 February 2025. As regent, Thungari initiated a
car free day program at Tahuna's town center, accompanied by public sports events and free medical checkups on weekends. ==Personal life==
