In this study, the research method used is a quantitative approach through survey methods. Analysis of the data used is to use the method of structural equation modeling, using SMARTPLS statistical computation tools. The way to collect the data needed in this study was carried out through questionnaires, interviews, and tests that had been prepared in advance. This study will examine the relationship between variables and measure the influence of each variable with each other, while the variables to be examined, namely: leadership (X1), quality of work-life (X2), job satisfaction (X3) and organizational citizenship behavior.

The population is a generalization area consisting of objects or subjects that have certain quantities or characteristics determined by researchers to be studied and then draw conclusions. Affordable population in this study are permanent workers who work at the head office of PT. Pertamina (Persero) MOR III Jakarta numbering: 217 people and PT. Pertamina (Persero) MOR V Surabaya numbered 142 people, with a total of 359 people. The target variable studied is organizational citizenship behavior (OCB) permanent workers who work at the headquarters of PT. Pertamina (Persero) Marketing Operation Region (MOR) III Jakarta and PT. Pertamina (Persero) Marketing Operation Region (MOR) V Surabaya. The number of samples is determined using the formula Taro Yamane or Slovin in Riadi (2018), as follows: where n, N are sample size and population number, respectively. In addition, d is the precision set, which is 0.05 when the level of confidence is 95%. In our study we have, 359/(3590.052+1) = 189. Based on Eq. (1) with an error rate of 5% of the population, then the sample taken amounted to 189 people, with details of 114 people MOR III Jakarta and 75 people MOR V Surabaya. The sampling technique uses a proportional random sampling technique. This technique is chosen based on the consideration that members of the population have the same opportunity to be chosen.
