Increasing Farmer Food Security and Incomes: Grain Storage Solutions Phase One
Technologies used:
Hermetic Bags/Airtight Drums Grain Storage Solutions
Local partner:
Kopernik Solo

Kopernik tested two grain storage solutions in Likotuden, East Nusa Tenggara, Indonesia. The experiment evaluated these solutions’ effectiveness in storing sorghum safely and eliminating weevils. This experiment tested a hermetic plastic bag and a hermetically sealed plastic drum.

Our hypothesis was that sorghum stored using a hermetic plastic bag or in a hermetically sealed plastic drum would have less weevils present compared to the traditional storage method (a plastic woven bag) and that this would lead to reduced grain losses. We also hypothesized that these storage methods would make stored sorghum safe from rodents.

Additionally, we measured the moisture level of the sorghum to ensure the new storage containers would not raise the moisture level beyond safe levels due to reduced airflow.

Our experiment concluded that both the hermetic plastic bag and hermetically sealed plastic drum:

  • reduced the number of weevils when compared to the traditional storage method
  • showed no sign of rodent infestation;
  • maintained the moisture level needed for safe human consumption.
