PERAN PEREMPUAN DALAM MEWUJUDKAN MODERASI BERAGAMA

Indonesia is unique with a diversity of languages, religions, cultures, tribes, customs and races. This variety of diversity requires religious moderation. Religious moderation is interpreted as a form of tolerance, both towards one's own religion and the religion professed by others. Religious moderation creates religious balance and harmony. This context of tolerance can be formulated as an attitude of openness in different views, by way of expressing and accepting views towards each other's beliefs. In realizing moderation, we need an active role from all parties, including women. Women have great potential in realizing and maintaining the tolerance required in this diverse Indonesia. The purpose of this study is to examine how the role of women in realizing religious moderation. The method used in this study is a descriptive qualitative method that refers to literature data. The results of this study show that the role of women will be the basic capital in realizing moderation in themselves, family, and society. It is hoped that the results of this study can encourage women to be actively involved in carrying out religious moderation

FTIR spectroscopy combined with chemometrics for analysis of lard adulteration in some vegetable oils

This study was aimed to develop a fast technique of Fourier transform infrared (FTIR) spectroscopy for detection and quantification of lard adulteration in some vegetable oils, namely canola oil (Ca‒O), corn oil (CO), extra virgin olive oil (EVOO), soybean oil (SO), and sunflower oil (SFO). The FTIR spectra associated with Ca‒O, CO, EVOO, SO, and SFO as well as their blends with lard were scanned, interpreted, and identified. The chemometrics of partial least square (PLS) and discriminant analysis (DA) at fingerprint regions of 1500–1000 cm−1 was used for quantifying and classifying of lard in the mixture with vegetable oils, respectively. PLS calibration can be successfully used for quantification of lard in the mixture with vegetable oils, either using normal spectra or its first derivatives. Furthermore, DA based on Mahalanobis distance can classify lard in vegetable oils. El objetivo de este estudio fue desarrollar una técnica rápida de espectroscopia de infrarrojos por transformada Fourier (FTIR) para la detección y cuantificación de adulteración con grasa de cerdo de algunos aceites vegetales, principalmente aceite de colza (Ca‒o), aceite de maíz (CO), aceite de oliva virgen extra (EVOO), aceite de soja (SO) y aceite de girasol (SFO). El espectrograma FTIR asociado con Ca‒O, CO, EVOO, SO y SFO, así como sus mezclas con grasa de cerdo, fueron escaneadas, interpretadas e identificadas. El análisis quimiométrico de mínimos cuadrados parciales (PLS) y análisis discriminantes (DA) en la región de 1500–1000 cm−1 se usaron para cuantificar y clasificar la grasa de cerdo en la mezcla con aceites vegetales, respectivamente. La calibración PLS puede ser usada satisfactoriamente para la cuantificación de grasa de cerdo en la mezcla con aceites vegetales, bien usando un espectro normal o sus primeras derivadas. Además, DA basados en la distancia Mahalanobis pueden clasificar la grasa de cerdo en aceites vegetales

FTIR spectroscopy combined with multivariate calibration for analysis of cod liver oil in binary mixture with corn oil

FTIR spectroscopy in combination with multivariate calibrations, i.e. partial least square (PLS) and principle component regression (PCR) was developed for quantitative analysis of cod liver oil (CLO) in binary mixture with corn oil (CO). The spectra of CLO, CO and their blends with certain concentrations were scanned using horizontal attenuated total reflectance (HATR) accessory at mid infrared (MIR) region of 4,000 – 650 cm-1. The optimal spectral treatments selected for calibration models were based on its ability to provide the highest values of coefficient of determination (R2 ) and the lowest values of root mean error of calibration (RMSEC). PLS was slightly well suited for quantitative analysis of CLO compared to PCR. FTIR spectroscopy in combination with multivariate calibration offers rapid, no excessive chemical reagent, and easy in operational to be applied for determination of CLO in binary mixture with other oils

Monitoring the oxidative stability of virgin coconut oil during oven test using chemical indexes and FTIR spectroscopy.

This study was conducted to evaluate the oxidative stability of virgin coconut oil (VCO) during oven test. VCO with and without antioxidants were subjected to oven test at 63°C over a 40 day-storage. The chemical parameters namely peroxide value (PV) and specific absorptivity of conjugated dienes (CDs) and conjugated trienes (CTs) were used to asses VCO stability. VCO samples treated with the mixture of butylated hydroxyanisole and butylated hydroxytoluene (BHA/BHT of 200 mg/kg) and citric acid (CA, 100 mg/kg) have lower PVs than control (VCO without antioxidants) and other treatments. The specific absorbtivities of CDs and CTs of VCO were also decreased due to the addition of antioxidants. In addition, Fourier transform infrared (FTIR) spectroscopy was used to monitor the peak changes during the thermal oxidation. The prominent peak change observed during thermal oxidation of VCO was at frequency 1739 cm-1 which corresponded to the carbonylic compounds (esters, aldehydes, ketones, lactones) resulted from the hydroperoxide decompositions during oven tes

Application of FTIR-ATR spectroscopy coupled with multivariate analysis for rapid estimation of butter adulteration

In dairy product sector, butter is one of the potential sources of fat soluble vitamins, namely vitamin A, D, E, K; consequently, butter is taken into account as high valuable price from other dairy products. This fact has attracted unscrupulous market players to blind butter with other animal fats to gain economic profit. Animal fats like mutton fat (MF) are potential to be mixed with butter due to the similarity in terms of fatty acid composition. This study focused on the application of FTIR-ATR spectroscopy in conjunction with chemometrics for classification and quantification of MF as adulterant in butter. The FTIR spectral region of 3910-710 cm⁻¹ was used for classification between butter and butter blended with MF at various concentrations with the aid of discriminant analysis (DA). DA is able to classify butter and adulterated butter without any mistakenly grouped. For quantitative analysis, partial least square (PLS) regression was used to develop a calibration model at the frequency regions of 3910-710 cm⁻¹. The equation obtained for the relationship between actual value of MF and FTIR predicted values of MF in PLS calibration model was y = 0.998x + 1.033, with the values of coefficient of determination (R²) and root mean square error of calibration are 0.998 and 0.046% (v/v), respectively. The PLS calibration model was subsequently used for the prediction of independent samples containing butter in the binary mixtures with MF. Using 9 principal components, root mean square error of prediction (RMSEP) is 1.68% (v/v). The results showed that FTIR spectroscopy can be used for the classification and quantification of MF in butter formulation for verification purposes
