JAKARTA, Indonesia — Michael Bambang Hartono, the visionary industrialist who transformed Indonesia’s Djarum Group into a multi-sector business empire, has died at age 86. The billionaire passed away Thursday afternoon at a Singapore hospital, according to an official statement released by the conglomerate he co-led with his brother Robert Budi Hartono.
The Djarum Group’s announcement expressed profound grief while acknowledging Hartono’s extraordinary dedication and service. While the precise cause of death remains undisclosed, the tycoon had previously disclosed struggles with chronic obstructive pulmonary disease and cardiac issues.
Together with his brother, Hartono expanded their inherited tobacco enterprise into a diversified conglomerate with substantial interests across banking, palm oil plantations, real estate development, electronics manufacturing, telecommunications, and digital commerce. Their flagship enterprise, PT Djarum, gained international recognition primarily through its kretek (clove-infused) cigarette production, manufacturing dozens of domestic and international brands.
The Hartono brothers maintained controlling ownership in Bank Central Asia, Indonesia’s largest financial institution, which reported revenues exceeding 57.5 trillion rupiah ($3.43 billion) in the previous fiscal year. Their combined net worth surpassed $43.8 billion, establishing them as Indonesia’s wealthiest individuals. According to Forbes’ December 2024 assessment, Michael Hartono’s personal fortune amounted to approximately $25.1 billion, ranking him 76th among global billionaires.
Beyond tobacco, the Hartono legacy includes the transformative redevelopment of Jakarta’s historic Hotel Indonesia into the Grand Indonesia complex—a premium mixed-use development featuring luxury retail, office spaces, and residential units. Through their holding company PT Dwimuria Investama Andalan, the brothers strategically diversified into technology, banking, and food sectors.
The magnate’s influence extended into professional sports through ownership of PB Djarum, Indonesia’s premier badminton club that has produced numerous world champions, and the Italian football club Como 1907. Under Hartono family ownership since 2019, Como achieved a remarkable ascent to Serie A in 2024 after two decades in lower divisions, currently competing for Champions League qualification while outperforming established clubs like Juventus and Roma.
In a personal tribute, Como 1907 acknowledged Hartono’s transformative leadership that ushered the club into a new historical chapter. The billionaire was also an accomplished bridge athlete, serving as president of the South East Asia Bridge Federation and earning recognition from the World Bridge Federation for his successful advocacy to include bridge in the Asian Games. At the 2018 Asian Games, Hartono won a bronze medal with the Indonesian team, becoming the nation’s oldest medalist at the competition.
Born October 2, 1939, Hartono grew up observing his father hand-rolling tobacco with native cloves to create kretek cigarettes—named for their distinctive crackling sound when burned. The brothers assumed control of the business following their father’s 1963 death, pioneering new blends and initiating exports to the United States and other markets by 1972. Their innovation produced Indonesia’s first machine-manufactured kretek cigarettes (Djarum Filter, 1976) and the iconic Djarum Super brand (1981), which remains dominant in the world’s fourth-most populous nation where over 64 million adults smoke daily.
Following U.S. restrictions on flavored cigarettes, Djarum adapted by marketing its clove products as “filtered cigars” using tobacco-leaf wrapping. The company continues to employ approximately 60,000 workers who manually produce cigarettes primarily targeting lower-income consumers.
Hartono is survived by his brother, wife, and son, leaving behind a legacy that reshaped Indonesian industry and commerce across multiple sectors.
