The secondary reserve in this study consists of demand deposits, placements in other banks, and securities, while bank reliability is measured based on total liabilities. The data used is secondary data from Bank Jatim's financial statements. The research method employed is multiple linear regression using IBM SPSS Statistics 25.</em></p> <p><em>The results show that the variable loans and sharia payments (X<sub>4</sub>) significantly affects the reliability of Bank Jatim, with a significance value of 0.029 (&lt;0.05). Meanwhile, the variables demand deposits (X<sub>1</sub>), placements in other banks (X<sub>2</sub>), and securities (X<sub>3</sub>) do not significantly influence bank reliability. The coefficient of determination (R²) of 0.229 indicates that 22.9% of the variation in Bank Jatim's reliability can be explained by secondary reserves, while the remaining percentage is influenced by other factors outside the research model.</em></p> Arivatu Ni'mati Rahmatika AN Rahmatika Trisna Putri Anggraeni Anggraeni Copyright (c) 2025 Trisna Putri Anggraeni Anggraeni, AN Rahmatika https://creativecommons.org/licenses/by/4.0 2025-03-27 2025-03-27 3 2 48 53 10.62375/jsintak.v3i2.490 The Effect Of Asset Level On Financial Tax Expense Performance At BRI Bank https://journal.iteba.ac.id/index.php/jurnalsintak/article/view/536 <p><em>This research aims to determine the level of tax assets on the performance of tax burden at Bank BRI.

This research was conducted at MAN 1 Polewali Mandar using quantitative research. The results showed that there was an influence between the Project-Based Learning Model on the Creativity Level of Students in class XI Religion MAN 1 Polewali Mandar. From the analysis obtained the coefficient of determination (R Square) of 0.406, which means that the effect of the independent variable on the dependent variable is 40.6% and as much as 59.4% is influenced by other factors not included in this study.</em></p> Mashita Darwis Okky Naomi Sahupala Copyright (c) 2025 Mashita, Darwis, Okky Naomi Sahupala https://creativecommons.org/licenses/by/4.0 2025-03-27 2025-03-27 3 2 61 65 10.62375/jsintak.v3i2.537 Identification of Variables Affecting Employee Performance Using Ordinal Logistic Regression https://journal.iteba.ac.id/index.php/jurnalsintak/article/view/552 <p><em>This study aims to identify the variables that most influence employee performance at PT. XYZ using ordinal logistic regression. Data was collected through an employee performance evaluation questionnaire covering variables such as professionalism, openness, integrity, kinship, and occupational health and safety (K3L). The research sample consisted of 36 employees selected using the random sampling method based on Slovin's formula. Data analysis was conducted through simultaneous tests, partial tests, and model fit tests to ensure the suitability of the ordinal logistic regression model used. The results showed that out of the five tested variables, only the kinship variable had a significant effect on employee performance (p-value &lt; 0.05). The resulting model met the goodness-of-fit test (p-value = 0.801), making it applicable for human resource management decision-making. These findings indicate that enhancing the culture of kinship in the workplace can be a key strategy for improving employee performance at PT. XYZ.</em></p> Reska Laelatul Khikmah Copyright (c) 2025 Reska, Laelatul Khikmah https://creativecommons.org/licenses/by/4.0 2025-03-27 2025-03-27 3 2 66 70 10.62375/jsintak.v3i2.552 The Effectiveness of the Desa Cantik Program in Village Data Management https://journal.iteba.ac.id/index.php/jurnalsintak/article/view/551 <p><em>The Desa Cinta Statistik Program (Desa Cantik) is an initiative by the Badan Pusat Statistik (BPS) aimed at enhancing village capacity in statistical data management to support evidence-based development planning. This study aims to evaluate the effectiveness of the Desa Cantik program in Kendal Regency, focusing on the satisfaction levels of village statistical agents and village officials regarding program implementation, village participation, BPS involvement, as well as the roles of relevant agencies and students in this program. The method used is quantitative descriptive analysis with a saturated sampling technique, involving 25 respondents from five selected villages in the program. The study results indicate that more than 75% of respondents are satisfied with the program's implementation, village participation, and BPS support. However, some challenges remain in coordination and community engagement. Therefore, optimizing socialization and strengthening coordination among stakeholders is necessary to improve the program’s effectiveness in the future</em></p> Kholishah Isnaini Laelatul Khikmah Copyright (c) 2025 Kholishah Isnaini, Laelatul Khikmah https://creativecommons.org/licenses/by/4.0 2025-03-27 2025-03-27 3 2 71 76 10.62375/jsintak.v3i2.551 Application of Simple Moving Average in Predicting Operational Expenditure at PT. Tri Tunas Unggul https://journal.iteba.ac.id/index.php/jurnalsintak/article/view/555 <p><em>This research aims to analyze and predict operational expenditure patterns at PT. Tri Tunas Unggul using the Simple Moving Average (SMA) method. The research data consists of daily operational expenditure records from July to October 2024. The analysis employs two SMA periods, 7-day and 30-day intervals, to identify both short-term and long-term expenditure trends. The results show that the 7-day SMA provides more responsive tracking of changes in daily expenditures, while the 30-day SMA reveals more stable long-term trends. The analysis identifies three significant peaks in the 7-day SMA in early August, late September, and mid-October, indicating cyclical spending patterns. This research demonstrates that the SMA method can be effectively utilized as a financial analysis tool to support decision-making in managing operational costs and investment strategies at PT. Tri Tunas Unggul.</em></p> Louis Lunardi Nahrul Hayati Copyright (c) 2025 Louis Lunardi, Nahrul Hayati https://creativecommons.org/licenses/by/4.0 2025-03-27 2025-03-27 3 2 77 84 10.62375/jsintak.v3i2.555
