A comparative study of three chemometric algorithms combined with NIR spectroscopy with the aim of determining the best performing algorithm for quantitative prediction of iodine value, saponification value, free fatty acids content, and peroxide values of unrefined shea butter. Multivariate calibrations were developed for each parameter using supervised partial least squares, interval partial least squares, and genetic-algorithm partial least square regression methods to establish a linear relationship between standard reference and the Fourier transformed-near infrared predicted. Results showed that genetic-algorithm partial least square models were superior in predicting iodine value and saponification value while partial least squares was excellent in predicting free fatty acids content and peroxide values. The nine-factor genetic-algorithm partial least square iodine value calibration model for predicting iodine value yielded excellent ( R2 cal = 0.97), ( R2 val = 0.97), low (root mean square error of cross-validation = 0.26), low (root mean square error of Prediction = 0.23), and (ratio of performance to deviation = 6.41); for saponification value, the nine-factor genetic-algorithm partial least square saponification value calibration model had excellent R2 cal (0.97), R2 val (0.99); low root mean square error of cross-validation (0.73), low root mean square error of Prediction (0.53), and (ratio of performance to deviation = 8.27); while for free fatty acids, the 11-factor partial least square free fatty acids produced very high R2 cal (0.97) and R2 val (0.97) with very low root mean square error of cross-validation (0.03), low root mean square error of Prediction (0.04) and (ratio of performance to deviation = 5.30) and finally for peroxide values, the 11-factor partial least square peroxide values calibration model obtained excellent R2 cal (0.96) and R2val (0.98) with low root mean square error of cross-validation (0.05), low root mean square error of Prediction (0.04), and (ratio of performance to deviation = 5.86). The built models were accurate and robust and can be reliably applied in developing a handheld quality detection device for screening, quality control checks, and prediction of shea butter quality on-site.

Near-infrared spectroscopy (NIRS) was used as a rapid and nondestructive method to determine the content of docosahexaenoic acid (DHA) in powdered oil samples. A total of 82 samples were scanned in the diffuse reflectance mode by Nicolet 5700 FTIR spectrometer and the reference values for DHA was measured by gas chromatography. Calibration equations were developed using partial least-squares regression (PLS) with internal cross-validation. Samples were split in two sets, one set used as calibration (n = 66) whereas the remaining samples (n=16) were used as validation set. Two mathematical treatments (first and second derivative), none (log(1/R)) and standard normal variate as scatter corrections and Savitzky—Golay smoothing were explored. To decide upon the number of PLS factors included in the PLS model, the model with the lowest root mean square error of cross-validation (RMSECV=0.44) for the validation set is chosen. The correlation coefficient (r) between the predicted and the reference results which used as an evaluation parameter for the models is 0.968. The root mean square error of prediction of the final model is 0.59. The results reported in this article demonstrate that FT-NIR measurements can serve as a rapid method to determine DHA in powdered oil.

Body mass index (BMI) is to monitor nutritional status adults, especially those related to deficiency and overweight. Body fat percentage can describe the risk of degenerative diseases.This study was conducted to measure the relationship between BMI and body fat percentage. Methods An analytical study was conducted to 41 male and 51 female participant from Universitas Teuku Umar. The body weight was measured using scales, whereas the body height was measured using microtoise. The body fat percentage was measured using Karada Scan. The BMI was calculated by dividing the body weight in kilogram divided by body height in meter square. Data was collected from 16-18th February 2021 and analyzed by Pearson’s correlation test. The results showed BMI underweight, normal, and overweight were 10,9, 57,6, and 31,5. High body fat percentage in men were 75,6% and in women were 35,5%. There is a relationship between the nutritional status of the women group and the body fat percentage with p-value is obtained = 0.021. Furthermore, for men, there is no relationship between nutritional status in the men group and the body fat percentage. There is a relationship between nutritional status and body fat percentage in women. Among this population, BMI can still be used to determine body fat percentage

ABSTRACTBackground: Anemia is a condition characterized by low levels of hemoglobin (Hb) from normal limits. Anemia is still a public health problem. Data states that the prevalence of anemia in Indonesia in 2013 was 21.7%, with the number of sufferers known to be higher in women than men. The prevalence of anemia in the age range 15 to 24 years was 18.4%. Nutritional status shows the balance of nutrients due to the consumption, absorption, and use of nutrients that come from food in the body. A person's nutritional status can be said to be deficient if the body lacks intake of one or more essential nutrients for the body. One of the indicators for assessing a person's nutritional status is the Body Mass Index (BMI). Inadequate nutritional status will affect the nutritional status of iron in a person' s body so that it can be interpreted that nutritional status is one of the factors of anemia. Consuming foods with good nutritional value, especially foods that contain high iron will also affect the nutritional status of these adolescents so that the risk of suffering from anemia will decrease.Objective: This study aims to analyze the relationship between body mass index and anemia among young women in Indonesia.Methods: This study is a cross-sectional study. The data used are secondary data from the Indonesian Family Life Survey (IFLS) 5. The population of this study was all Indonesians who participated in IFLS 5. The sample used in this study amounted to 3,525 respondents. IInclusion criteria of this study included female, aged 10-18 years, unmarried, having complete data regarding body weight, height and hemoglobin measurement results. If data related to the measurement results of hemoglobin, body weight, height are incomplete, they will be excluded.The statistical test was used is a chi-square test.Results: There was a relationship between Body Mass Index (BMI) and anemia among young women in Indonesia (p = 0.034 <0.05).Based on the odd ratio analysis using the normal Body Mass Index (BMI) group as a comparison, it is known that young women with underweight BMI categories have a 1.198 greater risk of experiencing anemia than girls with normal BMI categories.Conclusion: There is a relationship between BMI and anemia in adolescent girls. It is important for young women to always pay attention to daily iron intake by eating foods that are rich in iron or taking blood-booster tablets (TTD) to avoid anemia.

The frequency of underweight in children with cerebral palsy is about 60–70%. A benefit of nutritional support in children with cerebral palsy are underestimated. The use of nutritional support during active physical rehabilitation can have a positive effect on not only body weight, but also the component composition of the body and their rehabilitation potential.The aim of our study was to evaluate the effectiveness of nutritional support – a hypercaloric (1,5 kcal/ml) polymer formula with fibers (Pediashure 1,5 Fiber, Abbott) in children with cerebral palsy.Characteristics of children and research methods. Anthropometric indicators (body weight, height, body mass index, triceps skinfold thickness, subscapular skinfold thickness, mid-upper arm circumference, shoulder muscle circumference) and body composition were studied in 15 underweight children with cerebral palsy aged 4–10 years with the level of motor disorders GMFCSIII–IV. They were prescribed of nutritional support with a hyper caloric mixture (1,5kcal/ml) with fiber lasting 3months during active physical rehabilitation.Results. Against the background of nutritional support, there was a significant increase in body weight, height, z-score of body weight, mainly due to musculoskeletal, active cell and lean mass. In addition to correcting the nutritional status of children with cerebral palsy, an improvement in their motor abilities was noted.

Objective: The objective of this study was to develop a UV spectroscopy method in combination with multivariate analysis for determining vitexin in binahong (Anredera cordifolia (Ten.) Steenis) leaves extract. Methods: The partial least square (PLS) regression and the principal component regression (PCR) was performed in this study to evaluate several statistical performances such as coefficient of determination (R2), root mean square error of calibration (RMSEC), root mean square error of cross-validation (RMSECV), root mean square error of prediction (RMSEP) and relative error of prediction (REP). Cross-validation in this study was performed using leave one out technique. Results: The R2 values of calibration data sets resulted from PLS ​​and PCR method were 0.9675 and 0.9648, respectively. The low values of RMSEC and RMSECV both for PLS ​​and PCR method indicated the minimum error of the calibration models. The R2 values of validation data sets resulted from PLS ​​and PCR method were 0.9778 and 0.9820, respectively. The low values of RMSEP both for PLS ​​and PCR method indicated the minimum error of prediction generated from the calibration data sets. Multivariate calibration techniques were applied to determine the content of vitexin in binahong leaves extract. Predicted values from the multivariate calibration models were compared to the actual values determined from a validated HPLC method. It was found that PLS models resulted in the lowest REP values compared to the PCR models. Conclusion: The chemometrics technique can be applied as an alternative method for determining vitexin levels in the ethanol solution of binahong leaves extract.

Nutritional status in athletes is one of the important factors that affect athlete performance. Athlete's knowledge of nutrition is still lacking. Malnutrition and other health problems are found many in athletes. The purpose of this activity is trained athletes to improve the understanding of nutritional status and measure anthropometry to improve performance. This training contains materials that is needed to improve athlete's knowledge on nutritional status and anthropometric measurements. Further it can be used in the training process or in match conditions. This community service activity was attended by 29 participants consisting of female and male athletes as well as handball trainers. The activity is carried out online. Before and after the training participants fill out a google form for data on body weight, height, and questions about training materials. From the results of data processing, the average height for male athletes was 176 ± 6.33cm and for female athletes 164 ± 5.79cm. Meanwhile, the body weight of female athletes is 60.5 ± 8.3kg and male athletes are 74.02 ± 9.05kg. BMI in female athletes is 22.5 ± 2.2kg / m2 and in male athletes 23.88 ± 1.88 kg / m2. The mean pre-test score for female athletes was 60.35 ± 11.09, while for male athletes it was 60.35 ± 14.69. The average post-test score for female athletes was 67.85 ± 11.90, while for male athletes the average post-test score was 72.5 ± 9.20. Thus, the difference (gain) change in post-test scores to pre-test in female athletes is 12.43% and 20.12% in men. From this training, it can be concluded that there is an increase in the knowledge of handball athletes regarding nutritional status, nutrition, and dietary regulation in athletes. It is hoped that further this community service activity can be carried out in terms of determining the calorie and nutritional needs of athletes as well as athletes can be given knowledge about how to make food menus according to the needs of athletes.
