MAJOR SEAPORT CLOSURES

A Prewave Case Study

Indonesia, 2017

Strikes across major seaports 

Setting the scene for the TKBM cooperative to trigger a nationwide strike was the fact that their workers were not included in running costs of operations, and that the Indonesian government announced they would revoke the joint decree underpinning TKBM’s management.

 

Shortly after the first social media messages started appearing at grassroots level, Prewave formulated a strike alert without a date. By analysing further data and using machine learning technology, the Prewave engine was able to then consolidate and deliver a risk prediction as a strike alert with a definitive date. 

 

On the 4th December, port workers of TKBM (responsible for loading and unloading of cargo) held a national strike affecting dozens of seaports across Indonesia.
