There are many kinds of Agathis sp. having specific bark thickness in Indonesia. For example, at Buleleng Forest District Bali, where the investigation was carried out, there are two groups of Agathis sp. The first group is Agathis sp. known to have bark thickness greater than one cm, and the other group belongs to thin bark ( < 1cm). The bark thickness of Agathis sp. has a bearing on the resin yield. The resin itself is always coagulated quickly, there by requiring special treatment to produce optimal resin yield. This investigation is intended to select the Agathis sp. producing optimum resin yield and to increase the resin output by applying new tapping technique.

It ranges from 0.1 gram to 24.6 gram/tree/week with approximately 3.8 gram/tree/week average.Agathis sp. with thick bark give higher resin yield than those of thin bark.
