Perwali number 2 of 2021 regulates operational hours or curfews, which are also strengthened by a circular (SE).He explained several different things related to the implementation of PPKM and PSBB, including the 75 percent WFH (work from home) rule for workplaces or offices. Shopping centers or malls must close at 20.00 WIB. This decision also differs one hour later in the evening from the original Minister of Home Affairs Instruction at a maximum of 19.00 WIB. According to him, the decision should be taken at a maximum of 20.00 WIB in accordance with local wisdom.Responding to the implementation of PPKM, Reny Nugraheni, SKM., MM., M.Kes who was also a guest speaker at the event appreciated the government's steps to suppress the spread of Covid-19. According to him, restrictions on the mobility of people need to be taken by the government to protect public health. The PPKM option is needed because the transmission of Covid-19 has become more widespread. Because if human mobility can be limited, then transmission can be minimized. But besides that, the community must also carry out the protocol for washing hands, wearing masks, and maintaining distance (3M)."By complying with PPKM and 3M policies, we have tried to break the chain of Covid-19 transmission by protecting ourselves and protecting others," concluded Reny.
