Twenty one years old Denny Juswanto became the champion of DKI Jakarta for the second time. The first was in 1973 when he was only 14 years of age. The win was decided in the ultimate round when he beat Fabian J Lumentut.
The future Indonesian ace Utut Adianto was at 13th place.
Some pundits said at that time DKI Jakarta Champion title was much more prestigious than the national one.
