Abstract

Heavy metal pollution has become one of the most serious environmental problems today. The adsorption method is a relatively new process and has emerged as a potential alternative choice for removing heavy metals because it provides flexibility in design, the treated effluent is of high quality, is reversible and the adsorbent can be regenerated. This research aims to review articles that discuss several biosorbents from agricultural waste that are used to remove metal waste from the environment. The research uses the literature review method of several research results related to the literature on agricultural waste biosorbents in reducing metal waste in the environment. The research results show that agricultural waste from coconut shells, rice husks and corn husks is potential waste to be used as a biosorbent in the adsorption process because of its cheap price, abundant availability and sometimes pollutes the environment. Biosorbents from agricultural waste have good surface area and adsorption capacity in absorbing metal waste. The modification process for agricultural waste biosorbents is one of the processes that influences the morphology of the adsorbent and increases its adsorption capacity. Physical and chemical modification with thermal processes or the addition of acid and base compounds can increase the absorption efficiency of several adsorbents originating from agricultural waste.

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

Tempe wastewater still contains organic materials such as protein, fat and carbohydrates that are easily rotten, causing an unpleasant odor and damaging the aquatic ecosystem and environmental aesthetics. Tempe liquid waste contains nutrients (protein, carbohydrates, protein) so that it can be used for other production besides nata. The manufacture of nata de soya is nata derived from tempe liquid waste through a fermentation process using Acetobacter xylinum bacteria with concentrations of 100, 125 and 150 ml / l and sucrose concentrations of 100 gr, 150 gr and 200 gr with a fermentation time of 4 weeks. The parameters of nata de soya research analysis are color, texture, pH, thickness and weight. The results of Nata at a sugar concentration of 100 gr / l obtained the highest weight of 61.2 gr / l and at a sugar concentration of 150 gr / l the lowest weight was 66.7 gr / l while the heaviest nata was 181.7 gr / l at a sugar concentration of 150 gr / l. The average pH is the same, namely 3 and the thickness is between 0.5 to 1 cm, the average texture of all treatments is 20% -30% mm / g.sec. The optimal concentration for making nata de soya is at a sucrose concentration of 150 gr / l and an Acetobacter xylinum concentration of 150 ml / l because the results obtained are quite thick, namely a thickness of 1 cm and a weight of 183.8 gr / l.

Abstract

One of the most hazardous environmental pollutants that existed is silver liquid waste produced in photographic processing. Some types of water plants are believed to be able to absorb organic, inorganic, and other chemical compounds contained in liquid waste, water spinach (Ipoemea aquatica) being one of them. This study aimed to determine the effectiveness of water spinach (Ipoemea aquatica) in controlling silver liquid waste (Ag) contamination in water. The research design used was randomized block design. The data was then analyzed using a particular formula. The results of the study showed that after 15 days of treatment, water spinach (Ipoemea aquatica) was found to be effective in significantly reducing temperature and level of silver (Ag), but not the pH of the waste liquid. The highest effectiveness was observed when fifteen water spinach (Ipoemea aquatica) plants were used; temperature fell 17.90% (1.60% from the control value; and the level of silver (Ag) fell 5.30%

Abstract

Waste processing is currently being at the level of the government, especially solid waste, while liquid waste (leachate) has not been widely processed. Liquid waste is very disturbing to the environment because of the odor from the decomposition process of microorganisms and a little photolysis process. Leachate will cause the environmental carrying capacity to exceed and the impact of this leachate will continue because the community around the TPA location will use the river water that passes through the area to irrigate rice fields and other plants. Thus, it is necessary to conduct research on liquid waste (leachate) that is dumped into water areas, especially into rice fields, which can be used as liquid fertilizer after knowing the characteristics of the organic content in it using membrane technology. Leachate that has been centrifuged enters the feed tank and is then given a pressure of 1.2.3 Bar and a filter time of 15, 30, and 45 minutes. The results obtained are the performance of the Microfilter membrane so that the leachate flux is high, namely at a pressure of 2 bar with a time of 15 minutes, a flux value of 286 l / m2, hour will be obtained. The highest concentration of total nitrogen value was obtained at a pressure of 1 bar with a time of 15 minutes, which was 1920.800 mg/l. Based on the analysis of diversity on the total nitrogen value, it was obtained that the F count for the pressure factor was 1384.149 and the F count from the Time factor was 1231.843, when compared with the F value from the F distribution list (F table) it turned out that both were very significant as well as seen in the interaction
