Successful direct seeding-based post-mining land reclamation is hard to achieve. Multiple challenges including seeds carried along by runoff especially fine seeds (such as cajuput seeds) and poor soil conditions limit the effective germination of seeds and the establishment of desired plants. Seedcakes that contain organic pesticides are emerging as a direct tool to elevate reclamation success. Unfortunately, the place where seedcake is made is usually far from the planting area. Therefore, it is necessary to know how long the seedcake can be stored as an assumption of how long the distribution is.  This research aims to analyze the effect of seedcake storage on seed viability. Seedcake was made with composition water, adhesive, media itself, and organic pesticide with concentrations 0, 5, and 10 ml/L. Organic pesticides are applied by cajuput seeds that are soaked with organic pesticides, mixed with the adhesive, and sprayed on the seedcake before drying.  Seedcakes were stored for 0, 7, 14, 21, and 30 days before being planted on the plant media. The results showed that seedcakes can be stored for a month with the maximum germination rate on the seedcake with 0-day storage and 10 ml/L organic pesticide applied by soaking.
