The principle of episiotomy is the prevention of greater damage to the soft tissue due to the stretch that exceeds the adaptation capacity or tissue elasticity. The consideration of performing an episiotomy should refer to appropriate clinical considerations for the most suitable technique for dealing with the condition. This study aims to determine the relationship between birth weight and maternal parity with the incidence of episiotomy in PMB Norita Dahlia, S.ST in 2020. This study uses analytical methods. The population was all mothers who gave birth at PMB Norita Dahlia, S.ST, the sample was all maternal populations, namely 320 people with saturated sample techniques. The results showed that from 320 normal deliveries, 181 respondents who gave birth with birth weight> 3000 grams who experienced episiotomy were 95 (52.2%), and 139 respondents who gave birth with birth weight <3000 grams who experienced the action episiotomy as much as 42 (30.2%) .. With the results of the Chi Squre test р = 0.000 p <0.005, there is a significant relationship between variables of birth weight and episiotomy. The results showed that out of 320 normal deliveries, 144 respondents with parity primigravida who experienced episotomy were 90 people (62.5%), and 176 respondents with multigravida parity who experienced episiotomy were 47 people (26.7%) . With the results of the Chi Squre test р = 0.000 p <0.005, which means that there is a significant relationship between the parity variable and episiotomy.
