Computing infrastructure beneath the lake. Supporting Indonesia's digital resilience.
Jalaranu is developing the world's first eco-friendly modular underlake datacenter to evaluate thermal efficiency, operational reliability, and deployment feasibility in Indonesia.
We welcome collaboration with investors, institutions, and technology partners to establish a measurable foundation for development.
Why consider a location beneath a lake?
Underwater placement offers a different approach to heat management, physical space, and infrastructure access. Its potential benefits need to be assessed alongside the implications for deployment, maintenance, connectivity, and recovery.
The central question is: under what conditions would this approach be more feasible than a land-based datacenter using water-based cooling?
Jalaranu places that comparison at the centre of its evaluation.
Thermal performance
Assessing heat transfer and energy demand under defined site conditions and workloads.
Operational reliability
Testing how the system can be monitored, maintained, and recovered when disruptions occur.
Overall feasibility
Comparing whole-life costs and responsibilities towards the environment.
One system, from shore to submerged module.
The Jalaranu project connects shore-based support facilities with a computing module beneath the water. Planning covers power, connectivity, heat management, monitoring, and how the module is deployed and retrieved.
Shore facilities
Interfaces for power, networking, and operational management.
Shore-to-module connections
Power and communications routes to be designed around service-continuity requirements.
Underwater module
A computing enclosure and supporting systems to be evaluated through engineering and testing.
Monitoring and recovery
Observation of system conditions, incident response, and module retrieval.
Progress assessed through evidence.
Each development stage needs to answer specific questions: does performance meet the requirement, how does the system behave when it fails, what does it cost to operate, and how are environmental effects assessed?
Test plans, measured results, and their limitations provide the basis for decisions about further development.
