Analysis of Quality Control of Avtur Fuel in The Storage Tank at PT. XYZ on The Value of Electrical Conductivity During Covid-19

Abstract

In the process of receiving Avtur/Jet A-1 by PT. XYZ, the product received often does not meet the specification standard on the Electrical Conductivity. To overcome, doping Stadis 450 was carried out which could increase the Conductivity Unit. In the doping process, there are inefficiencies in the use of the Stadis 450. The result obtained indicates that all the final CUs are not following the CU target with an average difference of 41.67 pS/m. Also, the current pandemic conditions have resulted in the stockpiling of Avtur/Jet A-1 in the stockpile tank for a longer time. So that PT. XYZ increases the CU target in the doping process so the CU value can be appropriate when used. Determination of CU targets in trial and error without standard considerations will lead to waste in the use of Stadis 450 and increase the potential for discrepancies that occur in the doping process. To minimize, a reduction in CU Avtur/Jet A-1 is calculated as one of the suggestions in considering the CU target to be achieved. The result of the observed decline based on hoarding data showed that there was an average decline of 6.4646 pS/m per day.
