Abstract
Cirebon Waters holds a lot of potential in it, including as a place where many community activities take place in surrounding areas. This potential is not fully utilised due to the lack of information in these areas. In addition, the monitoring of the surrounding waters has not provided enough information, especially the turbidity parameter. In fact, information about a water body is very important for the development of the region. The observation of water quality can be conducted by in situ measurment, but direct measurement is considered to require extra work and cost. The development of a midi secchi disk and HydroColor application is expected to support citizenscience in communities in the Cirebon Waters. The minimalist shape of the midi secchi disk and the ease of accessing the midi secchi disk and HydroColor application are expected to simplify the observation of seawater quality. From this research, it was found that turbidity in Cirebon Waters ranged from 1,6-3,6 FTU. In this study, the accuracy of the two tools will be studied and the relationship of the results obtained with turbidity in Cirebon Waters to determine the condition of turbidity in the area by using Pearson correlation and p-value. The correlation between Forel-Ule scale parameter and electronic turbidity sensor data is relative high, with a correlation coefficient equal to R = 0.595 and the p-value is 0,0000408. Further development of the midi secchi disk and HydroColor needs to be done with some adjustments to develop science in the community.
