Tunnel Biorock RegrowthTrawangan Dive offers an innovative program aimed at restoring their reefs. The reef restoration program welcomes students around the world and is designed for gap year students, students looking for thesis and dissertation topics, people on career breaks and anyone interested in more than your average vacation!

Certain areas of shallow water corals around the Gili Islands have suffered damage by combinations of coral heatstroke, disease, land-based sewage, global sea level rising, over-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.

A revolutionary new technology called Biorock® can make this possible. The Biorock® Process involves a submerged steel structure that applies 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 to 63 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 Trawangan Dive for more information visit www.giliecotrust.com. 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.
 
Trawangan Dive offers a variety of training programs wherein students and volunteers would receive diver training from Open Water to Divemaster and the Biorock Specialty course. During their training they would learn about coral biology and environmental threats, be trained how to coral garden, survey, conserve, maintain the exciting Biorock® and finally design, weld and submerge their own Biorock® structure.

For divers interested in conservation, marine ecology or just wanting to give something back to the oceans, we have a range of Eco-dives that can be done from anything between one day and two weeks. Courses and training programmes run throughout the year on request.


Introduction to reef gardening – Single dive


  • Learn how to identify broken, overturned live corals that with our help, have a second chance of survival.
  • Learn how to safely pick up heavy corals and to find suitable substrate to transplant onto for the coral to attach to once overturned and secured.
  • Gain reef conservation skills you can take with you travelling and diving around the world
Dive includes all equipment including protective gloves and briefing on identification of corals to focus on and present reef state around the Gilis.

Price: 600,0000rp

Dive Against Debris - Single dive

  • Equipped with protective gloves and a mesh debris bag divers will go out in buddy teams to different reefs collecting as much non organic waste as possible.
  • Debris is separated, weighed and recorded onto a Project AWARE debris data sheet to submit to Project AWARE

Dive includes protective gloves and mesh bag, briefing and Dive Against Debris ID guide to know what to look for and collect, data sheets to analyse debris data.

Price: 590,000rp


Biorock Fun dive –Single dive


  • Learn what a Biorock is whilst diving around the world’s largest concentration of Biorock reef structures.
  • Briefing includes why the Gili islands reefs depend on artificial reef restoration. The basics of what a Biorock is and how it is advantageous to Gili islands tourism, fish populations and reefs.
  • Help our volunteers’ check the structures are on, working properly and harbouring the correct corals.
  • Bring along your underwater camera and get a picture on our very own Deus motorbike Biorock.

Dive includes short briefing on the Biorock technology, how long our Biorocks have been established, the age and condition of each Biorock you will see. Choose between a south Trawangan Biorock dive or North Biorock.

Price: 590,000rp


Introduction to the Biorock Process, 1 or 2 day PADI speciality (4 dives recommended)


  • Learn about coral ecology and the importance of coral reefs in the marine environment. The course raises awareness to the state of coral reefs global and the need for awareness and responsible behaviour to protect remaining healthy reefs.
  • Divers will also be introduced to the Biorock process and technology and why it is so successful.
  • Take part in training to identify damaged coral reefs, the causes of destruction and the use of Biorock technology for restoration and erosion prevention.
  • Learn how a Biorock works and why they are more successful than other reef restoration techniques. Will also gain an insight into how they are advantageous in preventing coastal erosion and eco tourism.
  • Gain a PADI Distinctive Speciality certification

Course includes 2 dives, at least one around the Biorock structures. The divers will learn to identify species of coral and the status of the corals on reefs and also on Biorock structures to compare. You will also learn how to recognize coral bleaching, disease and predation with underwater identification slates, whilst gaining a PADI speciality certification.

Price: 4,100,000rp

2 Week Biorock® Specialty and Reef Check Course


Students must have a minimum certification of Advanced Open Water to enroll in the 2 week program, but it only takes five days to complete both the PADI Open Water and Advanced courses. During the 2 weeks students will complete the PADI Biorock® Specialty course and Reef Check eco diver certification which allows candidates to complete reef surveys globally.  Participants will gain further knowledge and experience in reef ecosystem identification, reef survey techniques and coral gardening. During the first week there will be 2 dives conducted daily, theory time and lots of hands on practical work.  The second week will include designing, building and sinking a new structure.  This will then be connected whilst learning about Biorock maintenance.

Course Price: 10,000,000rp
