Abstract

This research was intended to formulate liquid bentonite soap using combination of corn oil andvirgin coconut oil used for cleansing najs mughalladzah (extreme najs). five formula of soap designated with I-Vapplying bentonite and combination of VCO and CO with different concentrations. The assessment of sopquality was based on organoleptic evaluation, foam stability, density, pH-value, and total of active component.Evaluation results were analyzed using simplex lattice design (SLD) to obtain optimum formula. Verificationof optimum formula was analyzed using one sample t-test with level of significance of 0.05. The resultsshowed that optimum concentration of bentonite was 6.5% with percentages of corn oil 85.43% and virgincoconut oil of 14.57%. Based on one sample t-test, there is no significant difference (pH > 0.05) from pH-valueresponse and foam stability between the predicted optimum formula as analyzed using SLD and actualformula. Bentonite liquid soap which is formulated using combination of corn oil and virgin coconut oilaccording to National Standardization Body SNI 2588:2017 so that the soap formula could be applied forcleansing najs mughalladzah.

Abstract

In this recent study, ATR-FTIR spectroscopy and chemometrics have been successfully used for theclassification and quantitative analysis of adulterated Pangasius Hypopthalmus (P. hypopthalmus) oil. The aimof this research was to evaluate the ability of ATR-FTIR spectroscopy and chemometric to perform theclassification and quantitative analysis of adulterated P. hypopthalmus oil in a binary mixture with palm oil(PO) and coconut oil (CO). In the development of FTIR spectroscopy combined with chemometrics for theclassification and quantitative analysis of P. hypopthalmus oil, P. hypopthalmus oil (MP and LFP) mixed withother oils such as coconut oil (CO) and palm oil (PO) at concentrations of 1-99% v/v. Classification of P.hypopthalmus oil, PO and CO were performed by the principal component analysis (PCA) and thequantification analysis was carried out by partial least square (PLS). Based on the optimization process, thebest classification results were obtained using the first derivative spectra at wave numbers of 1400-1100 cm-1.The prediction of percentage adulterated oil by PLS method also showed very good values of R2 greater than0.9999 and low standard error values in the range of 0.0176-0.703. The prediction was also perform at1400-1100 cm-1 wavenumbers using the first derivative spectra.
