| dc.description.abstract | . Chlorophylls and turbidity are related parameters deemed important in predicting water quality,
especially in the freshwater fisheries sector. In other hand, chlorophyll contents in vegetation are often used as a
measure for estimating plant health. To ensure the chlorophyll content, appropriate analysis techniques are
needed, which include, yet not limited to, dimethylsulfoxide (DMSO), acetone extraction analysis, and measuring
turbidity using expensive equipment. Measurements using these methods are still not reliable, especially for
smallholders. In addition, calibration of a digital camera for these purposes requires several efforts of preparing a
series of chemical analyses and the qualities of newly developed cameras have increased. Thus, calibration needs to
be taken into account for improving the accuracy in estimating chlorophyll contents. This study posits
fundamental findings germane to the potential use of chlorophyllin for calibrating the optimal instrument, like
consumer-grade cameras. Sodium copper chlorophyllin is commonly used as food additive and ingredients, and
medical treatments. However, we can gain another benefit of chlorophyllin, particularly for developing low-cost
optical instruments for estimating chlorophyll content through hydro-color-based with promising accuracy | en_US |
