Abstract

This study aims to determine the effect of Customer Relationship Management (CRM) on customer loyalty at PT Bank Mandiri (Persero) Tbk Padangsidimpuan Branch. The research method used is quantitative, with a data collection approach through observation, questionnaires, interviews, and documentation studies. Data analysis was carried out using simple linear regression techniques, hypothesis testing (t test), and the coefficient of determination (R²) test. The results showed that the regression coefficient value was +0.509, which indicated a positive relationship between CRM and customer loyalty. Hypothesis test analysis produces at value of +6.364 with a significance level of 0.000, which is smaller than 0.05. This shows that CRM has a positive and significant effect on customer loyalty partially. Based on the coefficient of determination analysis, the R² value of 43.9% indicates that CRM is able to explain 43.9% of customer loyalty variability, while the remaining 56.1% is influenced by other factors not discussed in this study. Thus, this study concludes that Customer Relationship Management has a significant influence on customer loyalty at PT Bank Mandiri (Persero) Tbk Padangsidimpuan Branch. These results strengthen the hypothesis that CRM is an important factor in building and increasing customer loyalty.

Abstract

ABSTRACT Fresh and chilled fish are the largest contributor to Indonesia's fishery product exports, accounting for a share of 45% or around USD 2.2 billion in 2021. The main destination countries for Indonesia's fresh and chilled fish exports include China, the United States, Japan, and other European countries. This research aims to analyze the factors influencing the export value of Indonesia's fresh and chilled fish, as well as to identify and evaluate the ARIMA (p, d, q) model based on historical data from 2012-2022. The result is an ARIMA (4,2,2) model with a MAPE value of 2.208 and a predicted value for the 2023 period of 4351 tons. This is in line with the large exports of fresh fish from Indonesia to various destination countries.

Abstract

This study aims to find out how smart governance influences to create a smart city on employee work productivity at the Governor's Office of North Sumatra. In this study, the authors used quantitative research methods. Data collection procedures in this study are observation (observation), interviews, documentation studies and questionnaires. Data analysis techniques in this study were correlation analysis, simple linear regression analysis, hypothesis testing (t test), and coefficient of determination test (R2). The results of the correlation test obtained that the correlation coefficient between variable X (Smart Governance) and variable Y (Employee Work Productivity) is 0.730. This means that variables X and Y have a strong influence because they have a correlation value that is at 0.60 – 0.799 (strong/high correlation). The results of simple linear regression coefficient calculations obtained a constant coefficient value of 3,084 and an independent variable coefficient (X) of 0,827 so that a regression equation Y = 3,084 + 0,827 X + ? or Employee Work Productivity = 3,084 + 0.827 Smart Governance + ?. The results of calculations with the t test (hypothesis) obtained a calculated t value of 8.614 which is greater than the t table value of 1.997 or 8.614 > 1.997 at a sig level of 0.000. So, the test results conclude that there is a positive and significant influence between variable X on variable Y, or in other words Smart Governance (X) has a positive and significant effect on Employee Work Productivity (Y) in the Office of the Governor of North Sumatra in the General Affairs and Equipment Bureau section. The test results using the coefficient of determination, obtained an R value of 0.730 while an R2 value of 0.533 means a coefficient of determination of 0.533 or R2 x 100% of 53.3%. That is, this value has implications that the influence of the Smart Governance (X) variable affects Employee Work Productivity (Y) at the North Sumatra Governor's Office by 53.3% and the remaining 46.7% is influenced by other variables not discussed in the study.
