Evidence status

Educational draft: initial reading does not replace academic and community review.

Movable forms

Floating kelong have buoyant components and can sometimes be relocated. Floats, nets, anchors and work platforms must be studied from documented structures, not assumed from a generic drawing.

Change in Bintan

A Riau Islands historical account reports movement from fixed to floating kelong in parts of Bintan, influenced by material availability and perceived economic returns. This does not imply a uniform timeline across islands.

STEAM lens

Learners compare buoyancy, surface area, current forces and maintenance considerations. Classroom calculations are conceptual and must not be used for offshore construction.

Learning question

What is actually supported by local sources, and what still requires direct investigation?
