Abstract

Floor cleaning products on the market usually use synthetic active that can interfere with health and the environment. Therefore, highly recommended to substitute synthetic active with natural active substances such as essential oils. The by-product of essential oils is hydrosol which is also not safe for the environment. This research aims to analyze hydrosol's effectiveness as an antibacterial and get an optimal formulation of oil essential and hydrosol as antibacterial in floor cleaning products. Kaffir lime leaf oil, lemongrass oil, and its hydrosol have been used as an additive in floor cleaners. pH value, free alkaline level, viscosities, and antibacterial effectiveness have been analyzed for floor cleaning products produced in this research. This research found a pH value of 6-8, viscosities is 1516-1867 cP, and free alkaline level of 0,1519-0,1627 b/b. The most antibacterial effectiveness found in the composition of kaffir lime leaf oil and its hydrosol is 15% and 30%, have bacteria inhibition of 10 mm. pH value, free alkaline, and viscosities have been fulfilled the standard of SNI 1842:2019.

Abstract

The residue of thermal power plants is known as coal fly ash and has been considered solid waste pollution worldwide. The characteristic of coal fly ashes showed that it contains several components that could be utilized in several fields. One of the potential utilization is in the agricultural application. This study analyzed the characteristic of two different types of coal fly ashes and their effect on the soil. The x-ray fluorescence (XRF) analysis resulted that SiO2, Al2O3, Fe2O3, CaO dan MgO are the five major components in the soil, and both coal fly ash, CFA A and CFA B. This XRF analysis result concluded that coal fly ashes have great potential to be a substitute for silica fertilizer. Then, the effect of the coal fly ash addition also was studied by the moisture content and nutrient (N, P, and K) content characteristics in the soil and the soil-ash mixture. The findings indicated that the addition of 125 grams of coal fly ash A had a greater impact on the soil compared to fly ash B when 250 grams of soil was used.
