Who We Are
Research on water systems, based on evidence that others can check.
We publish methods, plan monitoring and build early research tools to show how water conditions become risks. The work joins physical understanding, field observation, models and data analysis.
Observe
Monitoring, field data, satellite data and sensors.
Analyse & Model
Physics-based modelling, statistics, data analysis, and ML where appropriate.
Communicate & Test
Public methods, early research tools and research maps.
Machine learning, artificial intelligence and sensors are methods we may use. They are not the name or purpose of Reksar Lab. We pick a method that fits the question and the data.
Why We Exist
The water system is continuous. Information about that system is not.
Surface water, groundwater, water quality and data systems are often managed separately, while the physical water system itself remains connected.
Fragmented information
- Surface water
- Groundwater
- Water quality
- Data systems
- Different institutions
- Different mandates
Connected physical system
Rainfall → Catchment → River → Groundwater
Too MuchToo LittleToo DirtyPoorly Managed
Hazard, exposure and vulnerability combine to produce risk. Evidence then supports decisions — with limitations stated.
Mission & Research Principles
Understand the water. Say what the evidence can support.
To do open research that can be checked, answers real questions, and improves how water-related risk is understood and managed.
Mission and Statutory Purpose
Reksar Lab’s mission explains how Yayasan Rekayasa Sistem Air dan Risiko pursues its statutory purpose through water and environmental research. The foundation was established for social and humanitarian purposes. Its registered activities include research and development in the natural sciences and in engineering and technology, education, environmental conservation, and assistance to victims of natural disasters.
Physics first
We interpret results against how water actually behaves.
Only as complex as the data
We do not make models more complex than the evidence allows.
Useful for real questions
We study questions that matter for understanding water or deciding what to do.
Research Integrity & Independence
Trustworthy research shows its standards.
Transparency
Methods and assumptions are documented.
Reproducibility
We set up analyses so others can repeat them when the data allow.
Uncertainty
What is not known is reported.
Independence
Methods, findings and conclusions are determined by evidence.
