The physical properties of seed are required in designing an apparatus for handling, separation, drying, storage, and processing. The physical properties of white pepper seeds were determined as a function of moisture content in the range of 15,40 - 64,80 % dry basis (d.b.). The average height, length and width at a moisture content condition of 15,40 % (d.b.) were 4,11 ± 0,27 mm; 4,35 ± 0,34 mm and 4,35 ± 0,35 mm, respectively. In the range of moisture content 15,40 - 64,80 % (d.b.), the results of this study showed an increase linearly of the third axial dimension, the average diameter, the roundness from 0,969 to 0,977, the volume from 39,50 to 67,34 mm3, the surface area from 55,87 to 79,92mm2 and the thousand seed mass from 52,47 to 75,63 g. Bulk density and true density has a polynomial correlation with changes in moisture content.The porosity decreased from 45,01 % to 44,88 % with an increase in the moisture content range of 15,40 - 64,80 % (d.b.).

The objective of this work was to predict the soluble solid content, total acid, sugar acid ratio, and crude fiber of ‘Gedong Gincu’ mango non destructive using Near infrared Spectroscopy. Experiments were carried out using 182 samples of ‘Gedong Gincu’ mango. NIR reflectance spectra measurements were performed at wavelength of 1000-2500 nm using NIRFlex N-500 fiber optic solid. References data were collected from laboratory measurements. Five pre-processing treatments, smoothing 3 points (sa3), normalization (n01), first derivative Savitzky-Golay 9 points (dg1), combination (n01, dg1), and the Multiplicative Scatter Correction (MSC) were used to improve the accuracy of the calibration model. Partial Least Square (PLS) method was used to calibrate NIR data through references data. The results show that the best method for prediction of soluble non solid spectra were MSC and 12 factor of PLS with calibration value of Correlation Coefficient (r), Square Error Calibration (SEC), Square Error Prediction (SEP), Ratio of standard error prediction to deviation (RPD) were 0.91, 0.25 %, 0.39 %, 2.14 respectively. Sugar acid ratio content was predictd using MSC and 12 factor of PLS calibration with values of r, SEC, SEP, RPD were 0.81, 32.08 °Brix/%, 38.44 °Brix/%, 1.45. Soluble solid content was predicted using sa3 and 15 factor of PLS calibration with values of r, SEC, SEP, RPD were 0.82, 1.04 °Brix, 1.28 °Brix, 1.52 respectively. Total acid was predicted using dg1 and 3 with the value of r, SEC, SEP, RPD were 0.74, 0.01 %, 0.12 %, 1.33 respectively. It could be concluded that the developed model could be used to predict the chemical contents of ‘Gedong Gincu’ mango non destructively. ABSTRAKTujuan dari penelitian ini adalah memprediksi kandungan total padatan terlarut (TPT), total asam, rasio gula asam, dan padatan tidak terlarut (serat kasar) mangga Gedong Gincu secara non destruktif menggunakan spektroskopi inframerah dekat (NIR). Bahan yang digunakan berupa mangga Gedong Gincu sebanyak 182 buah. Pengukuran spektra reflektan NIR dilakukan pada panjang gelombang 1000 – 2500 nm menggunakan NIRFlex N-500 fiber optik solid dilanjutkan pengukuran data referensi laboratorium. Lima pra-proses data spektra yaitu smoothing 3 points (sa3), normalisasi (n01), first derivative Savitzzky-golay (dg1), kombinasi (n01,dg1), dan Multiplicative Scatter Correction (MSC) dilakukan untuk meningkatkan akurasi model kalibrasi. Kalibrasi data NIR dan data kimia dilakukan menggunakan metode Partial Least Square (PLS). Metode terbaik untuk prediksi padatan tidak terlarut diperoleh dengan pra-proses MSC dan kalibrasi PLS dengan nilai Correlation Coefficient (r), Square Error Calibration (SEC), Square Error Prediction (SEP), Ratio of standard error prediction to deviation (RPD) adalah 0,91, 0,25 %, 0,39 %, 2,14, dan faktor PLS 12. Kandungan rasio gula asam diduga dengan pra-proses MSC serta kalibrasi PLS dengan nilai r, SEC, SEP, RPD adalah 0,81, 32,08 °Brix/%, 38,44 °Brix/%, 1,45 dan faktor PLS yang digunakan 12. TPT diduga menggunakan pra-proses sa3 dan kalibrasi PLS dengan nilai r, SEC, SEP, RPD adalah 0,82, 1,04 oBrix, 1,28 °Brix, 1,52. Model kalibrasi total asam diperoleh pra-proses dg1 dan kalibrasi PLS dengan nilai r, SEC, SEP, RPD adalah 0,74, 0,01 %, 0,12 %, 1,33. Hasil penelitian ini menunjukkan bahwa model yang dikembangkan dapat digunakan untuk menduga kandungan kimia mangga Gedong Gincu secara non destruktif.

The objectives of this study were to characterize and evaluate the physicochemical properties of 10 cassava breeding genotypes developed by cassava crop improvement of (Institut Pertanian Bogor) IPB research group. The physicochemical characterization was performed by measuring water content, ash, protein, fat, carbohydrate, pasta (pasting properties), starch total, amylose content, and whiteness. The results showed that each genotype has different chemical content and gelatinization properties. The highest water content (11.48 ± 0.12 %) was found in genotype V4D0 (variant genotype Malang 4), ash (1.83 ± 0.02 %) in V5D2 (1) (A variant of genotype Malang 4-1), fat (1.62 ± 0.93 %) and protein (4.73 ± 0.19 %) in V3D1 (1) (variant UJ 5-1). Genotype V1D1-1(1) (A variant of genotype Ratim-1) has the highest amylose (23.33 ± 0.04 %) and the lowest ones (13.13 ± 0.48 %) was found in genotype V2D1-1(3). Genotype V2D0 has the highest total starch (88.67 %) and the lowest (74.3%) was obtained in V5D2 (1). The highest whiteness value was measured in genotype V1D0 i.e. 93.13 %. For pasting properties testing, it was measured that genotype V2D1-1 (3) had the lowest peak viscosity i.e 4,006 cP and the high of end of viscosity occurred 2,592 cP in genotype V4D2-1 (2) (A variant of genotype Adira 4-1), were correlated with high amylose content owned flour is 22.03 ± 0.25%.
