A men's doubles specialist, Heryanto and fellow countrymen
Hariamanto Kartono formed one of the world's leading teams between 1980 and 1985. As upstarts they earned silver medals at the
1980 IBF World Championships in
Jakarta, losing the final to veteran Indonesian teammates
Ade Chandra and
Christian Hadinata. At the 1981
All-England Championships they avenged that loss in the semifinal and went on to defeat another venerable Indonesian pair,
Tjun Tjun and
Johan Wahjudi in the final. They won the All-Englands again in 1984 and the
Indonesia Open in 1982 and 1983. In the momentous
Thomas Cup series of
1982 (China's debut) they split their matches against
China in
Indonesia's narrow 4—5 final round loss. After the partnership broke up, Heryanto won the
Thailand Open with
Bobby Ertanto in 1985. == Achievements ==
