The existence of the river becomes one of the important things in human life. In some the area even a river can be used to support the daily life of the community. In good and uncontaminated rivers, some bathing, washing even developing a fish cage farm is something that can be done. Yet another case if the presence of the river is polluted. In rivers that have high pollution, it will give many negative impacts that tend to harm the community located or exploiting the polluted river stream.
- Some of the negative impacts caused by river pollution among others is: Reduced source of clean water that can be used to support life human needs such as consumption, sanitation to agricultural irrigation sources.
- River water polluted by various types of pollutants, will become the media and also the nest various microbial sources of the disease.
- River water that has been polluted will also be the main vector or various vectors disease.
In Indonesia itself, it can be said that the level of pollution against river water is quite high. According to a report issued by the Directorate General of Pollution Control and Damage Environment Ministry of Environment and Forestry (KLHK), by 2015 level river pollution in Indonesia reached 67.94%. With reference to the report submitted it can be said that the majority of river water in Indonesia is at the level severe pollution.
By looking at the river water pollution problem, our team is doing research in the development of instrumentation used for monitoring the level of river water pollution. In this case, consider instrumentation design with cheap and affordable price is very possible to do. The design of this instrumentation consists of a microcontroller and WiFI module and some sensors to be used to detect the physical parameters indicates the level of pollution from river water.
