    　View Summary

    Classification and differentiation of clean sugarcane from trash (green sugarcane leaf, dry sugarcane leaf, stone, and soil) are important for the sugar payment system at a sugar mill. Currently, the methods used to do this are manual and subjective. Therefore, this study is aimed at accurately differentiating clean sugarcane from trash by using hyperspectral imaging with multivariate analyses. Samples containing sugarcane billets and trash mixed in a ratio of 18:38 were analyzed in this study. The reflectance data of the samples were analyzed in the wavelength range of 400–1000 nm via principal component analysis (PCA). The PCA model was capable of identifying all of the clean sugarcane and trash samples. The spectral loadings of the PCA model show that the sugarcane and trash samples are easily identifiable based on the color (visible light) of each class, water absorption (approximately 970 nm), and chlorophyll absorption (approximately 680 nm). Based on the characteristic wavelengths of the PCA loading peaks, over 90% of the sugarcane and trash samples were differentiated using a multiple linear regression model. Sugarcane and trash are classified by using partial least-squares discriminant analysis and support vector machine models. For all wavelengths, the classification rate is 92.9% and 98.2%, respectively. This shows that sugarcane and trash can be accurately classified and differentiated by using hyperspectral imaging and multivariate analyses.

  • Practical Use of Bioremediation Methods for Petroleum-contaminated Kunigami-maji Soil

    　View Summary

    <p>Field demonstration tests of the bio-pile and land-farming purification methods for remediating petroleum contamination were performed using the Kunigami-maji soil which broadly exposed on surface of the northern half of Okinawa Island. These methods involve the addition of phosphorus and nitrogen compounds or Ryukyu limestone particles to petroleum-contaminated soil. Both methods were found to be effective. The addition of Ryukyu limestone particles shortened the time needed for Total Petroleum Hydrocarbons (TPH) degradation to begin. Land-farming purification with no artificial air supply proved effective for the remediation of petroleum-contaminated Kunigami-maji soil. The lowered water content and pH neutralization may encourage the activation of petroleum-degrading microbes. In practical use, the relationship between petroleum odor and TPH concentration should be investigated with a pilot test on site. This pilot test determines the required period for purification from the TPH removal rate. The field demonstration tests discussed in this study give reference data gathered with nourishment and different of purification-promoting mthods.</p>
