Soap is obtained from the saponification reaction that occurs between oil and alkaline solution. Various kinds of oils used in soap making also affect the quality of soap. The purpose of this study is to determine the effect of oil type on the physical properties of liquid bath soap. This research was divided into 3 groups, coconut oil group (A), VCO oil group (B), and olive oil group (C). Liquid bath soap obtained from each type of oil is tested based on SNI provisions including a soap quality test (oil characteristics test, organoleptic test, pH test, specific gravity, total plate count), viscosity test, and antioxidant test. Liquid bath soap of the three types of oil has the same shape, color, and odor. Coconut liquid soap, VCO, and olives respectively have a pH value of 6.64; 6.9; 6.52. (P = 0,000) Specific weight 1.0511; 1.0427; 1.0425. Viscosity 558cps; 686; 420. (p = 0.003) IC50 3547.36; 4523.46; 3542.02. (p = 0.035). Bath soaps that best meet SNI requirements are those made with olive oil.

Single frequency microwave radiometry has been used to detect and estimate oil slick thicknesses. Because only a single sampling point is used, estimates of oil thickness can become ambiguous. MIT Lincoln Laboratory proposed the concept of using a frequency scanning radiometer to sample multiple points across a frequency band, thus resolving the problem of ambiguities in oil thickness estimation. A laboratory-prototype FSR capable of scanning over Ka-band (26 -40GHz) was designed, built, and tested. The FSR was used in laboratory proof-of-principle testing to (1) measure uniform thickness oil layers under various ambient weather conditions (day, night, clear, cloudy, drizzle, and snow) and different oil types, and (2) measure the phenomenology of non-uniform thickness oil layers and emulsions. Comparisons of measured data sets with theoretical predictions demonstrated that the expected response of oil is consistent regardless of oil type or ambient weather condition. Comparisons of uniform oil layer measurements and non-uniform measurements with theoretical predictions indicate that the radiometric brightness temperature (TB) of the oil above that of water is a function of the percentage of that thickness of oil within the antenna field-of-view. Water/oil emulsions were measured and have a higher TB than a uniform layer of pure oil at the same thickness. Recommendations for FSR modifications and improvements, as well as future collection work are included. -BKA
