Latex moisture content measurement and Analysis using RGB-based indices

Malaysia Rubber Research Institute of Malaysia (RRIM) produces several rubber clone series at the research institute such as RRIM 2002, RRIM 2007, RRIM 2008, RRIM 2014 and RRIM 3001. We investigated the use of MCS600 Carl Zeiss spectrometer with the wavelength of the visible light spectrum (VIS) ranging from 400 to 900 to identify the rubber clone series based on the various moisture content. The obtained reflectance measurement index was next analyzed to observe the differences for these clones based on RGB color spectrum using SPSS (Statistical Package for the Social Sciences) software tool. From the results obtained, one-way ANOVA analysis were used to observe the relationship between rubber clone identification by using color spectrum and moisture content. From the findings, it can be concluded that green and blue color spectrum is able to differentiate the various clones at 100 % level of moisture content.
