Background of wastewater generated by various activities in the hospital environment after going through the process of treatment at the Environmental Health Installation the result of phosphate parameters which is 4.88 mg / l exceeds the quality standard of Central Java Regulation No. 5 of 2012 which is 2 mg / l, so that it has the potential to pollute the environment if the parameters contained therein exceed the specified quality standards. Liquid wastes containing phosphates and cause environmental problems in the form of eutrophication, namely water pollution caused by the large amount of nutrients in the aquatic ecosystem. The research objective is to determine the Effect of Lime and Alum Dose Solution in Reducing Phosphate in Liquid Waste in RSUD dr. M. Ashari Pemalang Year 2020. The sample used 36 samples. The research method used is quasi-experimental research. The research design used in this study is the pretest and post-test design before treatment and after treatment with different doses of lime solution and alum solution, with the Paired sample T test. The results at pH have an effect after the addition of lime solution and alum pH rises so that it is alkaline in wastewater, for phosphate after adding a dose of lime solution 26.37 gr / l and alum 26.85 gr / l, 14.55 gr / l and alum 17.46 gr / l there is an influence on the decrease in phosphate by value 0,000 mg / l (P 0.05) for addition of 10 gr / l lime solution and 10 gr alum / alum with a value of 0.007 mg / l (P 0.05). Conclusions are all significant but researchers prefer the 10 gr / l lime and 10 gr / l alum because of the effect on the sediment is slight, the pH is not basic and the temperature also has no effect.
Folklore was born as the product of the culture in society; it can be in the form of myth, legend, or tale. In folklore, there are cultural value and wisdom that can be used as the guidance of life for the society, such as, democratic value, the value of hard-working, the value of honesty, moral, and love to their country. Those values lie in Cilacap’s folklore. Their existence takes part in the increase of tourism visit, which, at the end, hopefully, can increase the society’s economic level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
