Used refined cooking oil can be used to make soap. An important factor in the manufacture of soap is the saponification reaction between bases (KOH) and fatty acids. The addition of citrus essential oil to the soap preparation can increase consumer acceptance. This study aims to determine the effect of KOH concentration on the characteristics of liquid soap and to determine the proper concentration of KOH to produce good quality of liquid soap. This research uses a factorial completely randomized design with one factor that is KOH concentration, consisting of three levels ie 25%, 30% and 35%. Characteristics of liquid soap observed were viscosity, foam height, pH, and free alkali content. The results showed that the concentration of KOH effect on the characteristics of  liquid  soap  produced. If  KOH concentration increases,  viscosity,  pH and alkali-free  alkali content of the liquid soap increased. The best KOH concentration is 25%.

ABSTRACT Brazil is the world’s largest producer of sugarcane (Saccharum officinarum L.) and research aimed at propagation has promoted higher quality in production. The objective of this study was to investigate the effect of the variation of micrometeorological elements on the survival and quality of pre-sprouted sugarcane plantlets. The study was carried out in a protected environment (UFRPE). Plantlets of the cultivar RB92579 were obtained by the technique of production of pre-sprouted plantlets. The protected environments were divided into four modules covered with low-density polyethylene plastic + photo-selective shade nets and one module without shade net. Micrometeorological data of global and photosynthetically active solar radiation, air temperature, substrate temperature, relative humidity and the solar radiation spectrum were recorded in each module. The experiment was conducted in a completely randomized design and the principal component analysis was used to verify the association between the cultivation modules, micrometeorological variables and crop variables. Anti-UV low-density polyethylene plastic + freshnet led to lower transmittance of global solar radiation, higher percentage of photosynthetically active radiation and lower plantlet mortality. Substrate temperature above 30.2 °C resulted in higher plantlet mortality. Larger spectrum in the red range led to the production of better quality plantlet. The use of freshnet shade net promoted adequate conditions for the cultivation of sugarcane plantlets and allows obtaining better quality plantlets.
