This study aimed at understanding the impact of direct consumption allowance, motivation and supervision on the service quality of caring at the Regional Public Hospital (RSUD), in Larantuka. The main issues addressed in this paper were (1) Providing an overview of the impact of direct consumption allowance incentive, motivation, and supervision on the care service quality at RSUD, Larantuka. (2) Was there partial correlation of direct consumption allowance incentive, motivation and supervision, on the care service quality at RSUD Larantuka? (3) Was there a significant simultaneous impact of direct consumption allowance incentive, motivation and supervision on the care service quality at RSUD Larantuka? The aim of this study was to get an overview of the impact of those variables on the service quality of RSUD, Larantuka through a comparison of free variables and bound variables, either partial or simultaneous. The population covered by this study consists of the 350 RSUD employees. The sample involved in this study were 187 responders, selected through stratified sampling, whereas all the employees where divided by frame sampling in a series of batches or categories. The distribution of samples in the respective category has been selected through simple random sampling. Data analysis was carried out by descriptive and inferential statistics (multiple linear regression analysis). In order to assess the influence of the free variables compared to the bound variables in a simultaneous way, this study applied a F-test while also applying a partial correlation t-test. The descriptive analysis results showed that all the free variables were valid, which were also the case for the bound variables. The results of the inferential statistics showed that in a simultaneous approach, all the three free variables showed a positive and significant impact on the care service quality. However regarding partial correlation, only the supervision system variable has a positive and significant impact on the care service quality. The managers of the RSUD Larantuka were advised to keep on improving the supervision system, through the creation of an Internal Appraisal System, in order to provide patients with better care in the future.
