Tramena Dive Center has an innovative program to restore the Gili islands’ reefs. We welcome gap-year students and those looking for thesis or dissertation topics; those on career breaks or anyone wanting an interesting and worthwhile holiday activity.

Certain areas of shallow water corals around the Gili Islands have suffered damage by combinations of coral heatstrokediseaseland-based sewageglobal sea level risingover-fishing and direct physical damage. Restoration of degraded reefs and coastal habitats on a scale that makes a difference must be an active environmental priority and not an afterthought.

revolutionary new technology called Biorock can make this possible. The Biorock Process involves a submerged steel structure that receives a safe low-voltage electrical current. Small pieces of live broken coral are then strapped to the structure and have been shown to grow at 3-5 times the normal rate while coral survival under higher water temperatures and pollution increased by 16 to 50 times.

The Gili Islands are the second largest Biorock site in the world, currently home more than 120 Biorock structures and have hosted International Reef Restoration Training Workshops. The reef restoration project is coordinated by the Gili Eco Trust which works closely with the DKP (Indonesian Marine Conservation and Fisheries). Head of the Gili Eco Trust is Delphine Robbe who oversees the Biorock project around the Gili Islands and here at Tramena Dive Center. For more information visit

Since 2004 when the first Biorock reef was installed many development and research students from Indonesian and other Universities around the world have come to study the Biorock reef restoration project as part of their Thesis or Masters Degree. Our hope is to continue these projects and make the Gili Islands a global centre for coral research and re-growth.
