Abstract

The massive Covid-19 pandemic has caused countries to implement policies in the form of social restrictions to limit activities outside and only carry out activities indoors. The risk of contracting the Covid-19 virus causes a reduction in public activities in the form of commercial, institutional, and public service facilities. This has an impact on the amount of waste generated by people in urban areas during the pandemic. Therefore, this study aims to determine the effect of covid-19 on the amount of waste that enters the Toisapu TPS in Ambon city and to see the difference in the average amount of waste before the pandemic and during the COVID-19 pandemic with Paired Sample T Test analysis using IBM SPSS statistics 25 application. The results showed that there was a correlation between the two variables (0.693) which means that the correlation of the amount of waste entering the Toisapu TPS between before and during covid-19 was strong but not significant as indicated by the probability value (sig.) 0.013 0.05. While the calculated t value is 3.16 2.63 (t table value) so it can be concluded that the average amount of waste before and during the Covid-19 period is different.                 Keywords: Pandemic, waste, T test

Abstract

Polyphosphate is a straight chain biopolymer consisting of tens to hundreds of phosphate residues that are linked by high energy phosphoanhydride bonds, polyphosphate plays an important role in the bioremediation process of uranium waste, especially in the process of uranium metal precipitation in bacterial cells. Some bacteria are known to have the potential to interact with uranium through redox transformation and bioprecipitation by releasing inorganic phosphate to bind uranium in the environment. Inorganic phosphate results from degradation of polyphosphates that accumulate in cells. This study aims to determine the ability of uranium-tolerant bacteria to accumulate polyphosphates during their growth phase. Measurements were made in 5 growth phases, namely the lag phase, the logarithmic phase, the beginning of the stationary phase, the stationary phase, and the stationary end. Quantitative analysis of polyphosphate accumulations was carried out using the Olsen & Dean method. The test results are known that the uranium-tolerant bacterial isolat is able to accumulate the most optimal polyphosphate in the stationary phase, especially at the 48th hour and the lowest polyP accumulation is found in the initial stationary phase at the 24th hour.
