Acid rain event is very dangerous for human activity especially in five cities of Indonesia. Here, acid rain has consistently attacked over five cities in Indonesia such as Jakarta, Manado, Pontianak, Bogor, and Surabaya with average pH level 4.22 to 6.34 in July 2010. Thus, in this study aim to develop Fiber Optic Chemical Sensor (FOCS) for monitoring acid rain level over five cities in Indonesia. The development of FOCS is used evanescent wave type and photodiode FDS10X10 to monitor acid rain quality. In this study, the Optical Power Meter (OPM) is used as a validator equipment to capture FOCS capability. The result shows absorption loss was successfully detected using OPM and photodiode FDS10X10 in FOCS evanescent wave type. Here, the maximum value ammonia mass over acid rain level has successfully detected with value range 7.12 dBm to 8.34 dBm and 7.51 dBm to 7.71 dBm using photodiode FDS10X10 and OPM, respectively. The good result over validation process shows FOCS has successful working with strong correlation 0.78 to monitor acid rain level. © Published under licence by IOP Publishing Ltd.
