Daniel explains, “Operating the solar-powered boat is23 a revelation; it runs smoothly, silently, and without the polluting effects of fossil fuels.” The change is strikingly evident. Previously, the roar and smoke of diesel engines disrupted the tranquility of Telaga Nirwana, detracting from the natural beauty and guest experience. Now, the serene silence enhances the ambiance, allowing tourists to enjoy undisturbed conversations and appreciate the sounds of nature.
This shift was propelled by a collaborative effort led by the German Federal Ministry for Economic Cooperation and Development (BMZ), executed through GIZ, alongside local partners such as PT Chakra Giri Energi Indonesia. This partnership has been crucial in implementing sustainable technologies that align with both local needs and global environmental goals.

“The difference now is significant,” notes Daniel. “The clean, quiet rides not only improve our tours but also help preserve the pristine condition of our waters.” This initiative is part of a broader movement towards sustainability, supported by international cooperation, which ensures that advancements in renewable energy are accessible and beneficial at a community level.

This successful integration of solar-powered boats in Rote Island exemplifies how targeted technological interventions can lead to substantial environmental and social benefits, positioning Indonesia at the forefront of renewable energy adoption within the maritime tourism sector
