Yongki Aribowo scored the only goal for the home team right at the death.
This defeat won't come as a surprise to any readers of my Jakarta Globe column as I predecited earlier this month the game in Banjarmasin could be a banana skin for Jacksen F Tiago's men.
Of course one defeat does not mean their season will come off the rails and Persipura are still odds on favourite for the ISL.
