Profile of Michael Bambang Hartono: The Life Journey of the BCA Owner and Djarum Business Empire
Michael Bambang Hartono passed away today, Thursday (19/3), at the age of 86. He featured on Forbes’ list of the richest people. He is a symbol of perseverance who successfully transformed a small cigarette factory nearly destroyed by fire into a cross-sector conglomerate that supports the national economy. Born as Oei Hwie Siang on 2 October 1939 in Kudus, Bambang Hartono closed his life in March 2026, leaving behind a sprawling business legacy from banking to green technology.
Bambang Hartono’s business journey began from the lowest point when his father Oei Wie Gwan’s Djarum factory was severely burned in 1963. Together with his younger brother, Robert Budi Hartono, he rose and undertook phenomenal diversification.
For Bambang Hartono, the card game Bridge was more than a hobby. He was a national athlete who contributed a bronze medal for Indonesia at the 2018 Asian Games. According to him, Bridge is the best training for making business decisions: gathering data, analysing risks, and executing strategies calmly.
Despite having a net worth estimated at Rp297 trillion to Rp315 trillion in 2026, Bambang Hartono was known for his extremely modest lifestyle. One iconic moment continually remembered by the public is when he was caught on camera enjoying dinner at a roadside Tahu Pong stall in Semarang without tight security.

Besides Djarum cigarettes, the group owns BCA, Polytron, Blibli, Tiket.com, and the Italian football club Como 1907.
