Abstract

Abstract. The use of ethanol and biodiesel, which are alternative fuels or biofuels, has increased in the last few years. Modern official standards list 25 parameters that must be determined to certify biodiesel quality. In order to determine biofuel quality, several methods were already widely used in which most of them were based on solvent extraction followed by other laboratory procedures. Yet, these methods are expensive, laborious and complicated processing for samples. Near infrared reflectance spectroscopy (NIRS) can be considered as a fast, pollution-free and non-destructive method in determining biofuel quality parameters. The objective of this study is to apply near infrared technology in classifying biodiesel based on KOH (0.3, 0.5 and 0.7) and to predict related biodiesel quality properties (water content, linolenic fatty acid, oleic acid,  and stearic acid) based on its infrared reflectance. Biodiesel infrared spectrum was acquired in wavelength range from 1000 to 2500 nm for different mentioned three KOH content. Principal component analysis (PCA) with non-iterative partial least square (NIPALS) was applied to analyze biodiesel spectral data. The result showed that two principal components (PC1=97% ad PC2 = 2%) based on infrared reflectance data were successfully able to recognize and classify biodiesel based on their used KOH. Moreover, the wavelength range of 1000 – 1140 were to be believed related to linolenic fatty acid whilst 1450 nm and 1930 nm were associated with water content. Stearic acid can be predicted in wavelength range of 1330 – 1380 nm and wavelength range of 1725 – 1790 nm were related to oleic acid of biodiesel. This may conclude that infrared technology was feasible to use as a rapid, effective and non-invasive method in biofuel classification and evaluation.

Abstract

Abstract. Near infrared technology have been widely applied in many fields, including agriculture especially in sorting and grading process. The advantage of this technology: simple sample preparation, rapid, effective and non-destructive. The main objective of this study is to evaluate the feasibility of NIR technology in classifying several agricultural products based on their electro-optic properties. NIR diffuse reflectance spectra of apples, bananas, mangoes, garlics, tomatoes, green grapes, red grapes and oranges were acquired in wavelength range of 1000-2500 nm with gradual increment of 2 nm. Chemometrics methods were applied in combination with NIR spectra data. Classification was performed by applying principal component analysis (PCA) followed by non-iterative partial least square (NIPALS) cross validation. The results showed that NIR and chemometrics was able to differentiate and classify these agricultural products with two latent variables (2 PCs) and total explained variance of 97% (88% PC1 and 9% PC2). Furthermore, it also showed that multiplicative scatter correction (MSC) was found to be effective spectra correction or enhancement method and increased classification accuracy and robustness. It may conclude that NIR technology combined with chemometrics was feasible to apply as a rapid and non-destructive method for sorting and grading agricultural products. Rapid Classification Of Agricultural Products Based On Their Electro-Optic Properties Using Near Infrared Reflectance And ChemometricsAbstract.

Abstract

Abstrak. Proses grading telur menggunakan mesin merupakan salah satu upaya untuk meningkatkan kapasitas grading telur dengan hasil grading yang lebih seragam. Permasalahan yang sering terjadi dalam proses grading telur adalah posisi telur yang tidak sesuai. Hal ini menyebabkan telur tidak akan terbawa oleh konveyor grading sehingga dapat menghambat proses grading. Metode yang digunakan dalam penelitian ini adalah dengan membuat alat uji untuk mengubah posisi telur, selanjutnya menguji panjang lintasan rol pengarah, jarak sumbu rol pengarah dan grade telur terhadap perubahan posisi telur. Penelitian ini dilakukan untuk membuktikan pengaruh panjang lintasan dan jarak sumbu rol pengarah serta grade telur terhadap perubahan posisi telur untuk mencapai posisi sejajar dengan rol pengarah. Hasil pengujian menunjukkan bahwa panjang lintasan dan jarak sumbu rol pengarah memiliki pengaruh yang sangat signifikan terhadap perubahan posisi telur, sedangkan grade telur memiliki pengaruh signifikan terhadap perubahan posisi telur. Jarak sumbu rol semakin lebar dan ukuran telur semakin kecil akan mendapatkan hasil yang semakin baik, hal ini ditunjukkan dengan perubahan posisi telur sejajar rol pengarah semakin cepat tercapai. Hasil terbaik untuk mendapatkan posisi telur sejajar dengan rol pengarah diperoleh pada perlakuan jarak sumbu rol pengarah 6 cm untuk telur grade C. Experimental Study of Changes Position of Eggs on Eggs Grading Machine Abstract. The grading process of using the eggs grading machine is one of the efforts to increase the capacity of the eggs grading with grading more uniform results. The problems that often occur in the process of grading eggs are the position of eggs is not perfect. That is causes the eggs will not be carried away by the grading conveyor so that can inhibit the process of grading. The method used in this research is to create a test tool to change the position of the eggs, then test the path distance of convey roller, width axis of convey roller and eggs grade against the eggs position changes. This research was conducted to find the influence of path distance and width axis of convey roller as well as eggs grade against the eggs position changes to achieve equal position with the convey rollers. The test results show that the path distance and width axis of convey roller have a very significant effect, whereas eggs grade have a significant effect on changes in the position of the egg. The increasing of width axis of convey roller and the smaller size of the eggs will get better results, as shown by changes in the position of the eggs to parallel the convey roller more quickly achieved. The best results obtained on the width axis of convey roller distance is 6 cm for grade C of eggs.
