This research aims to investigate the adulteration of Khao Dawk Mali 105 rice based on storage age using Near-Infrared Spectroscopy (NIRS) with Fourier Transform Near-Infrared Spectroscopy (FT-NIR) in the wavenumber range of 12,500 – 4,000 cm-1 (800 – 2,500 nm). Storage duration significantly impacts the quality of cooked rice. This research is divided into two parts: 1) to investigate the feasibility of separating rice according to storage age (1, 2, and 3 years) using the best model created by an Ensemble method combined with Second Derivative, which achieved an accuracy of 96.3%. 2) To investigate adulteration based on storage age by adulterating at 0% (all 2- and 3-year-old rice), 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 100% (all 1-year-old rice). The best model was created using Gaussian Process Regression (GPR) combined with Smoothing + Multiplicative Scatter Correction (MSC), with coefficients of determination (r²), root mean square error of prediction (RMSEP), bias, and prediction ability (RPD) values of 0.92, 8.6%, 0.9%, and 3.6 respectively. This demonstrates that the adulteration model can be applied to separate rice by storage age (1, 2, and 3 years). Additionally, the color values of rice with different storage ages show differences in L* and b* values.
โรงงานผู้ผลิตข้าวพบปัญหาการปลอมปนของข้าวสารที่มีอายุการเก็บรักษาต่างกัน โดยทั่วไปการคัดแยกการปลอมปนจะใช้วิธีมาตรฐานโดยการหุงข้าว จากนั้นนำข้าวหุงสุกไปวัดเนื้อสัมผัสเพื่อแยกอายุของข้าว ซึ่งใช้เวลาและเป็นการทำลายตัวอย่างและเกิดความล่าช้าในการตรวจสอบคุณภาพข้าวสาร งานวิจัยนี้ใช้เทคนิคเนียร์อินฟราเรดสเปกโทรสโกปี (Near-Infrared Spectroscopy, NIRS) ในการตรวจสอบการปลอมปนของข้าวสารพันธุ์ขาวดอกมะลิ 105 (KDML 105) ที่อายุการเก็บรักษาต่างกันเพื่อแก้ไขปัญหาดังกล่าว

This study aimed to develop a website for collecting and organizing data on Young Smart Farmers in Chanthaburi Province. Data were collected through structured interviews with a sample of 30 participants. The information obtained was categorized and utilized to develop the website, which was subsequently disseminated to farmers and other stakeholders. The study also assessed user satisfaction with the website through a questionnaire, with data analyzed using descriptive statistics, including frequency, percentage, mean, and standard deviation.The results indicated that the sample comprised an equal proportion of male and female participants, with the majority (50.00%) aged between 36 and 40 years. Most respondents were Young Smart Farmers from the districts of Khlung, Laem Sing, and Kaeng Hang Maeo, each representing 13.33% of the sample. The majority of participants had attained a bachelor’s degree or equivalent (60.00%) and were primarily engaged in agricultural occupations (73.33%). The findings on user satisfaction with the website revealed a high level of satisfaction across all dimensions, ranked as follows 1) Website usability (Mean 4.97), 2) Overall satisfaction (Mean 4.93), 3) Content quality (Mean 4.91), 4) Practical benefits and applicability (Mean 4.87), and 5) Design and layout (Mean 4.85).
