Rivers of Yogyakarta
There are three main rivers which passes through the urban areas of Yogyakarta, Code River, Winanga River, and Gajahwong River. lifepatch collaborating with many communities have conducted a project called Jogja River Project (JRP) on these rivers. These project is also part of Biodesign For The Real World, a collaboration between (Art)Science Bangalore, École Polytechnique Fédérale de Lausanne (EPFL) and lifepatch.
For the HLab2014, the River Node will focus on the Code River, one of the three rivers that run through Yogyakarta. The river is essential for the local community, for example, who raise fish in the traditional kerambas. However, the river has become polluted with plastic and other wastes , and the coliform bacterial contaminations are high. Seasonal flooding is also an issue. April, when the HLab2014 will take place, will be the beginning of the dry season.
We will kick-off the 3 weeks of HLab2014 by taking a walk along the Code River and mapping existing kerambas.
The aim is to prototype 2 types of monitoring stations: a static buoy model, inspired by the traditional keramba, and a swimming robot, inspired by aquatic robots and old school toy boats.
We will be building one each (static, swimming) over the course of the HLab2014 period, over a week, with extensive testing and measurement taking by the river next to Lifepatch head quarters.
STATIC STATION: The keramba are traditional anchored fish farms found through the river where currents are slow - we will work with local community members to learn to build a traditional keramba, which will offer fish farming as well as hydroponic plant growth and with a careful choice of plants, some toxin fixation.
SWIMMING ROBOT: We will start with a simple boat or even a fish (!), first to get our feet wet as soon as possible.
These stations will be MEASURING:
Conductivity, Temperature, Depth: http://www.rockethub.com/projects/26388-oceanography-for-everyone-the-openctd pH Turbidity Flow rate E. coli detection -(faster, more quantitative) microcolony formation: http://www.youtube.com/watch?v=iJxDZi0CwrA Geolocalization, GPS Geiger counter? COD - my MFC-technology (Malthe) can potentially be used to detect toxic chemical compounds - Other ways to do this?
We will be working on these projects under the umbrella of the Hardware Node.
In addition to mapping the existing kerambas, we would like to GPS map the swimming robot location, and possibly directly send the information onto a map.
The Jogjya River Project already has a map started.

Possible camera streaming
Data visualization will remain a challenge
Water sensing is important, however, water purification is also very important.
During the hackterialab, we would also like to
- Collect oral narratives from the local communities to find out what people used to do in the olden days to clear water - a folklore type of project
- This is inspired from this paper, where folklore pointed scientists to use a positively charged Moringa oleifera seeds to clarify the water before UV treatment (PET bottles and sun).
- The recent paper using different tree bark to filter out bacterial particles seems very testable.

Publiclab's data loggers and others
Besides intersting work on spectrophotometers and other nice webtools, like infragram, they also started some water monitoring, using the mchack platform for logging of temperature and conductivity:
Interesting low-cost logger based on MCHCK
Our friends in Bangalore have been continuing their work on a water quality test for drinking (F, As and e-coli). First with some hardware and color detection, now using a smart phone interface. contact arun and sam.
