The purpose of this study was to analyze the effectiveness and potential hazards, assess risks, control risks at the head office during the Covid-19 pandemic. The process of office activities carried out by PT. Praja Ghupta Utama has the possibility of a high risk of exposure to the workspace area. Therefore, potential hazards must be analyzed with one of the risk analysis methods, namely JSA (Job Safety Analysis). The JSA method is used to analyze existing hazards, determine risk assessments and classify each hazard based on its risk level. The JSA method can reduce the potential for work accidents by managing a series of activities carried out. PT. Praja Ghupta Utama applies elimination controls, modification techniques, and personal protective equipment (PPE) to reduce exposure or accidents and risk management and also has excellent results in knowledge and behavior related to occupational safety and health and good on knowledge of JSA.","PeriodicalId":127483,"journal":{"name":"JURNAL TECHLINK","volume":"292 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135893277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, rice husks were prepared with two treatments: non-activating and with 30% NaOH activation after being heated in a furnace at a temperature of 400 oC for 1 hour then the adsorbent was sieved with particles that passed through a 40 mesh sieve. The adsorbent was used to absorb 200 ml of Pb ions with an adsorbent weight of 5 grams, where the adsorption process was carried out in 2 contact times, 60 minutes and 120 minutes and tested in the laboratory.
