Abstract

Declining cocoa productivity in East Kalimantan is influenced not only by agronomic practices but also by the quality of planting materials used. Poor-quality seeds with reduced vigor tend to germinate slowly and inconsistently, which ultimately leads to the formation of weak and non-uniform seedlings.  This study aimed to evaluate the potential of several indigenous bacterial isolates derived from golden snail- and goat rumen-based bioactivators in enhancing cocoa seed vigor. The experiment was carried out in a greenhouse at Politani Samarinda using a Completely Randomized Design (CRD) with one factor consisting of five treatments, namely an untreated control (P0) and bacterial isolates P103 (P1), P107 (P2), P204 (P3), and P206 (P4), each with three replications.  Observed variables included germination percentage, germination speed, and germination uniformity. The analysis showed that bacterial treatments did not produce a statistically significant effect on germination percentage. However, they significantly influenced germination uniformity and had a highly significant effect on germination speed. Among all treatments, isolate P103 consistently showed the most favorable performance across all measured parameters, recording a germination percentage of 91.11%, a germination speed of 9.85% day⁻¹, and a germination uniformity of 77.78%.  These results indicate that isolate P103 has strong potential as a bioagent for improving cocoa seed vigor and could be further developed to support the production of high-quality cocoa seedlings.
