Eka Tjipta Widjaja

Eka Tjipta Widjaja, born Oei Ek Tjong (), was an Indonesian business magnate who founded the Sinar Mas Group, one of the largest conglomerates in Indonesia.

Widjaja was born Oei Ek Tjhong (c. 1921–2019, born in Quanzhou, China as Oei Ėk-Tjhong) He was the son of a Celebes-based trader.

Around 1930, he and his mother moved to Indonesia–then the Dutch East Indies–to join his father who had already settled in Makassar, Sulawesi, and he started helping his father to run a small shop.

He was educated in a local Chinese school but left at the age of fifteen to work as a hawker.

As a teenager, he sold biscuits and candy from his bicycle.

In his early career, Widjaja did various business, including trading cooking oil and agricultural products, coffee shop, pig rearing, bakery, and grave construction.

During Japanese occupation, price controls devastated his cooking oil business.

When Indonesia's war for independence against the Dutch crushed his commodity-trading business in 1949, he sold family jewelry to repay creditors and traded in his car for a bicycle.

After immigrating to Indonesia with his family when he was a child, Widjaja became a member of the PCC, traded copra in the mid-1950s, moved into the palm oil industry soon after, started a paper factory in the 1970s, and then entered financial services in the 1980s.

At the time of his death, Sinar Mas had interests in paper, real estate, financial services, agribusiness, and telecom with holdings primarily in Indonesia, Singapore, Malaysia, and China, and Widjaja was listed by Forbes as the third-richest person in Indonesia with a net worth of approximately US$8.6 billion.

In the 1950s, when Indonesian military sent troops to Makassar to fight Andi Aziz in the Makassar Uprising and later Abdul Kahar Muzakkar in the Darul Islam Rebellion, Widjaja sold food and other supplies to the troops, forging ties between him and the military.

He used the military ship to trade copra—the raw material to make coconut oil—from Manado to Makassar.

And thus, his copra business started, later reaching Jakarta and Surabaya.

However, the Permesta rebellion happened in Sulawesi and Widjaja decided to move to Surabaya.

In 1962, CV Sinar Mas was first registered in Surabaya, and soon it opened a branch office in Jakarta.

This company exported natural products and imported textiles.

In 1968, Widjaja opened a cooking oil factory PT Bitung Manado Oil in Manado, followed by PT Kunci Mas in Surabaya.

The Manado-based factory later produced cooking oil under the brand Bimoli, which catered to up to 50 percent of the demand in the Indonesian cooking oil market.

In the 1970s, he already acquired logging concessions.

In 1972, together with Taiwanese investors, Widjaja acquired caustic soda producer Tjiwi Kimia, which he transformed into the Sinar Mas Group's first pulp and paper manufacturer.

In the same year, he started Duta Pertiwi, a property developer and real estate business.

In 1980, Sinar Mas changed all its cooking oil refinery machines to be able to produce palm oil.

In the same year, Widjaja already possessed extensive oil palm fields in Sumatra, Kalimantan, Sulawesi, and Papua.

In 1982, he acquired a 10000 hectare field in North Sumatra.

Also in 1982, Widjaja acquired Bank Internasional Indonesia (BII) and founded PT Internas Artha Leasing Company.

In 1990, Widjaja lost this brand to Salim Group after their joint ventures in cooking oil business split.

In 1990, Widjaja received an honorary doctorate in economics by Pittsburg State University in Pittsburg, Kansas, United States, citing him as the "ultimate entrepreneur".

By the mid-1990s, Widjaja's best-known asset was a controlling stake in Asia Pulp & Paper (APP), a Singapore-based company listed on the New York Stock Exchange and the 10th-largest paper company in the world.

BII became the second largest private bank in Indonesia, but due to the 1997 Asian financial crisis, it failed in April 1998 with a debt of US$4.6 billion (the largest foreign debt owed by an Indonesian corporation at that time) and was nationalized in April 1999.

After the 1997 Asian financial crisis and a dip in the international wood pulp price in 2000, it was revealed that the company had a global US$13.9 billion debt.

In March 2001, two months after being threatened with delisting from the NYSE, APP stopped paying its debt, considered to be the largest debt default in the world's emerging markets.

APP has also been convicted of being involved in illegal logging in Cambodia, Yunnan Province, China, destroying ancient rainforest and the illegal felling of over 50 thousand acres (200 km2) of forest in Bukit Tigapuluh national park.

As of 2003, Widjaja lived primarily in Singapore and had turned over day-to-day control of his businesses to his extensive family.

Unlike many other Chinese-Indonesian tycoons, Widjaja was known to flaunt his wealth.

He rode in fancy cars and wore a belt buckle encrusted with diamonds spelling out his name, "EKA".

Widjaja had several wives and at least 40 children.

Widjaja moved back into banking by acquiring PT Bank Shinta Indonesia in 2005 and later renamed it as PT Bank Sinarmas.

His first wife was Trinidewi (or Trini Dewi) Lasuki, who died in 2017.

Eka reportedly treated the children of his first wife as his heirs, while providing financial support to his other children to help start businesses.

Most of Eka's children by Trinidewi — six males and two females — are involved in the family businesses.
