Abstract

Indonesia is the world’s largest producer of palm oil. To preserve its competitive advantages, the Indonesian oil palm sector must expand high-quality palm oil output. In oil palm quality control, the water content is a crucial parameter as it can be used as a reference to determine the right harvest time. Thus, this study proposed a near-infrared (NIR) spectroscopy as a fast and non-destructive analysis to assess oil palm water content. NIR spectra were processed using Shannon entropy to describe the characteristics at each wavelength. In this study, oil palm fruit samples at various maturity levels were collected with eight different maturity fractions. Based on the analysis, the Shannon entropy value is closely related to any changes in the water content of palm oil. The entropy value has a decreasing trend as the water content increases. The proposed technique can predict the water content of an oil palm with satisfactory performance with values of 0.9746 of coefficient of determination (R2) and 2,487 of root mean square error (RMSE). Application of this model will lead to a fast and accurate prediction system related to oil palm water content.

近红外光谱法无损测定油棕含水量的香农熵

印度尼西亚是世界上最大的棕榈油生产国。为了保持其竞争优势，印尼油棕行业必须扩大高品质棕榈油的产量。在油棕质量控制中，水分含量是一个至关重要的参数，它可以作为确定合适采收时间的参考。因此，本研究提出了一种快速、无损的近红外光谱分析方法来评估油棕的水分含量。利用香农熵对近红外光谱进行处理，描述各波长的特征。本研究采集了8种不同成熟度的油棕果实样品。通过分析可知，香农熵值与棕榈油含水量的变化密切相关。熵值随含水率的增加呈减小趋势。该方法预测油棕含水量的决定系数(R2)为0.9746，均方根误差(RMSE)为2487，结果令人满意。该模型的应用将建立一个快速准确的油棕含水率预测系统。
