PENGARUH 90 DAYS PLANNER DAN KELENGKAPAN DATABASE DOKUMEN TERHADAP KINERJA DEPARTMEN CREWING DI PT CIPTA WIRA TIRTA

Abstract

The performance of the Crewing Department at PT Cipta Wira Tirta determines vessel operational continuity and compliance with international maritime regulations. The company faces obstacles such as unstandardized short-term work planning mechanisms and incomplete crew document databases. This condition triggers administrative delays, rework, and deviation cases between planned and actual crew changes. This study aims to analyze the partial and simultaneous effects of 90 Days Planner implementation (X1) and crew document database completeness (X2) on the performance of the Crewing Department (Y) at PT Cipta Wira Tirta. The researcher used a quantitative approach with an explanatory research design. Primary data collection utilized a Likert scale questionnaire through a saturation sampling (census) technique on 32 respondents from a total population of 32 employees. Data analysis methods applied multiple linear regression assisted by SPSS version 26 software. The $t$-test results prove that the implementation of the 90 Days Planner has a partial positive and significant effect on department performance with a contribution of 77.6% tcount = 4.990 > ttable = 2.04227). The completeness of the crew document database also has a partial positive and significant effect with a contribution of 66.4% tcount= 2.653 > ttable = 2.04227). Simultaneously, both independent variables have a positive and significant effect with a combined contribution of 81.9% to the variation in department performance Fcount = 65.769 > Ftable = 3.33). These findings confirm that the integration of timeline planning controls and database quality accelerates the verification process and supports accurate seafarer placement. This study concludes that systematic placement schedule management and disciplined data updates optimize the long-term operational performance of the crewing division. Company management needs to standardize the 90 Days Planner digital dashboard, conduct weekly monitoring meetings, and implement an automatic early warning alert system for certificate expiration dates. Future researchers are advised to expand the scope of the study by increasing the research sample size.
