Abstract

According to research, corn husk waste contains alkaloid compounds with antioxidant activity of 43.13% which functions to increase collagen production, reduce fine lines and wrinkles, reduce black spots and treat acne. Meanwhile, the eggshell membrane contained in eggshells contains collagen and protein which can help rejuvenate the skin and increase skin elasticity. Utilizing the potential of organic waste corn husks and eggshell membranes as a source of antioxidants and collagen for raw materials for skin care cosmetics has advantages in terms of economics and environment. Because it can reduce waste generation, it can also be economically profitable. The aim of this research was to determine the physical quality of a peel-off mask made from corn husk extract and eggshell membrane powder. As well as identifying antioxidant activity and collagen mask content in peel-off masks. Peel-off masks from these two materials meet the physical quality test for peel-off masks. With a pH ranging from 6.5-6. Spreadability between 4.2-5.5 cm. Drying time ranges from 14-24 minutes. The IC50 value of the peel off mask is 7785.87 ppm which shows that there is no antioxidant potential in the product. Identification of collagen using the FTIR method indicates the presence of a secondary structure of â-sheet protein which shows that the existing collagen has not been degraded into gelatin

Abstract

An increase in the number of facilities that serve public health can increase the potential for environmental wastewater pollution, there by impacting human health problems and environmental pollution. The aim of the research is to determine the planning of the RSU X domestic wastewater treatment plant using anaerobic-aerobic biofilter technology. The research method uses a qualitative descriptive approach. The research population was all RSU X liquid waste, the sampling technique used non-probability sampling in the form of saturated sampling, while the research sample was domestic liquid waste at RSU X. The research results show that the Waste Water Treatment Plant (IPAL) planning is designed to treat waste water of ± 30 m3 / day, with a capacity of 60 beds. The removal efficiency of waste water characteristics in the inlet chamber tank, grease trap tank, equalizing tank, anaerobic biofilter tank, aerobic biofilter tank, sedimentation tank and chlorination tank. Efficiency of chlorine requirements for disinfection, CH4 generation efficiency, and sludge generation efficiency.
