Environmental Monitoring of the Rivers in Yogya
<- back to main page of HackteriaLab 2014 - Yogyakarta
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 (http://v-images2.antarafoto.com/gps/1279541715/pemanfaatan-sungai-15.jpg). However, the river has become polluted with plastic and other wastes (http://lifepatch.org/File:Wawies_moto_sungai.jpg), and the coliform bacterial contaminations (http://biodesign.cc/2013/03/18/investigation-of-coliform-bacteria-contamination-at-the-rivers-of-yogyakarta/) are high. Seasonal flooding is also an issue. April, when the HLab2014 will take place, will be the beginning of the dry season.

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.
