Air Cargo Inflow–Outflow Dataset (2021–2025) – Indonesian Major Airports

This dataset contains monthly air cargo movement data (in metric tons) for six major airports and a composite "Other Airports" group in Indonesia from 2021 to 2025. It includes both inflow (goods unloaded) and outflow (goods loaded) volume records. The data was compiled from the official Indonesian Central Statistics Agency (BPS) at https://www.bps.go.id/id/statistics-table/2/MjM1MSMy. It has been preprocessed and formatted for use in time series forecasting and logistics modeling, as demonstrated in the associated research paper on predicting export-import demand using the Prophet model.
