Abstract

Platform X social media has become a platform for people to express their opinions, including on issues related to Pertamina. This study aims to analyze public sentiment on Platform X towards Pertamina using the ID3 (Iterative Dichotomiser 3) algorithm-based Decision Tree method. The data used are 2,005 tweets collected with the keyword "Pertamina Corruption". The data went through a preprocessing stage which includes case folding, tokenizing, stopword removal, and stemming. Text features were converted into binary representations (Binary Weighting) of 10 main keywords such as 'corruption', 'pertamina', and 'prosecutor'. The ID3 Decision Tree model was built recursively by selecting separator attributes based on the highest Information Gain value. The results showed that the built model had excellent performance. Evaluation on testing data (20% of the total data) produced an accuracy of 98.50%, with a precision value of 97.98%, a recall of 98.50%, and an F1-score of 98.22%. The 5-fold cross-validation results also confirmed the model's stability, with an average accuracy of 98.30% and a low standard deviation (0.0046). The contains_korupsi attribute was identified as the most informative root node in the decision tree structure. The conclusion of this study is that the Decision Tree method with the ID3 algorithm has proven effective and reliable in classifying public sentiment toward Pertamina on Platform X with high accuracy. The results of this analysis are expected to be used by Pertamina in understanding public opinion and formulating more appropriate communication strategies.

Abstract

Digital image security is an important issue in this era of increasingly massive multimedia-based data exchange, especially for sensitive information that requires a high level of protection. This study aims to analyze the performance of the Rivest Shamir Adleman (RSA) asymmetric cryptography algorithm in the digital image encryption process based on the Mean Squared Error (MSE) and Peak Signal-to-Noise Ratio (PSNR) parameters, as well as encryption and decryption times. The method used is a quantitative experiment on 30 digital images with varying resolutions (256×256, 512×512, and 1024×1024 pixels) and two RSA key lengths (1024-bit and 2048-bit). The test results show that the MSE value ranges from 0.001068 to 0.002620 and the PSNR value ranges from 75.08 to 78.34 dB, indicating that the decrypted images are of very high quality and close to the original images. However, the computation time increased significantly with increasing resolution and key length, with RSA 2048-bit taking almost twice as long as RSA 1024-bit. These findings show that the RSA algorithm is very effective in maintaining the integrity of digital images, but has limitations in terms of computational time efficiency, especially for high-resolution images. Therefore, a balance between security and performance is needed in practical implementation.

Abstract

The development of TikTok as a digital marketing medium This study aims to analyze the effect of price, service, comfort, product availability, and payment method on the shopping decisions of boarding-house students in the Padang Bulan area, Medan, at minimarkets and traditional markets. A quantitative approach was used with a purposive sampling technique involving 120 boarding-house students who had shopped at both minimarkets and traditional markets in the area. Data were collected through a five-point Likert-scale questionnaire and analyzed using multiple linear regression, preceded by validity, reliability, and classical assumption testing. The results show that all five independent variables simultaneously have a significant effect on shopping decisions, with a coefficient of determination of 0.669. Partially, comfort and payment method have a positive and significant effect on shopping decisions, while price, service, and product availability show no significant effect. Payment method is the most dominant variable influencing shopping decisions, followed by comfort. These findings indicate that transaction convenience and a comfortable shopping environment are the main considerations for boarding-house students when choosing where to shop, more than price, service quality, or product completeness. The findings suggest that both minimarket and traditional market managers should continue improving shopping comfort and expanding digital payment options to strengthen their competitiveness among student consumers.

Abstract

Teamwork is a crucial skill that helps students complete group projects. However, differences in participation levels, communication, responsibility, and task allocation often hinder collaborative learning. This study aims to analyze the impact of team collaboration on the success of students' group assignment completion. This study employed a quantitative approach using a survey method, distributing questionnaires to 105 active students with experience completing group projects. Data analysis was performed using IBM SPSS through validity, reliability, normality, simple linear regression analysis, partial t-tests, and the coefficient of determination (R²). The research findings indicate that team collaboration has a positive and significant effect on the success of group assignment completion. The regression equation obtained is Y = 6.285 + 0.763X, indicating that each increase in team collaboration is accompanied by an increase in the success of group assignment completion. The t-test results showed a significance value of 0.000 (<0.05), thus supporting the research hypothesis. The coefficient of determination (R²) of 0.525 indicates that team collaboration can explain 52.5% of the variation in the success of group assignment completion, while the remaining 47.5% is influenced by other factors not included in the study. This study indicates that communication, coordination, active participation, responsibility, and efficient task distribution are crucial elements in increasing the success of student group assignment completion.

Abstract

Students' punctual attendance at lectures is fundamental to the smooth conduct of academic activities; however, in reality, many students still arrive late, with the mode of transportation often cited as a contributing factor. This study aims to examine the influence of the chosen mode of transportation on the frequency of student lateness for lectures, determine its relationship with travel time to campus, and identify transportation-related obstacles that may trigger such lateness. The study employs an associative quantitative research design involving 120 active students selected via convenience sampling; data were collected online using a Google Forms questionnaire with a five-point Likert scale. Instrument validity was assessed using Pearson's product-moment correlation coefficient, while reliability was tested using Cronbach's alpha; both tests yielded valid and reliable results. Classical assumption testing—including Kolmogorov-Smirnov and Shapiro-Wilk normality tests and the Glejser test for heteroscedasticity—indicated that the regression model met the prerequisites for further analysis. Simple linear regression analysis yielded the equation Y = 12.958 − 0.145X. The t-test produced a significance value of 0.312 (> 0.05), as did the F-test (0.312 > 0.05), indicating that the mode of transportation does not have a significant influence on student lateness. The coefficient of determination (R²) was only 0.009, meaning that the mode of transportation accounts for only 0.9% of the variation in student tardiness, while the remaining 99.1% is influenced by factors outside the scope of this study, such as time management, personal discipline, travel distance, and traffic conditions.

Abstract

The rapid adoption of Artificial Intelligence (AI) in higher education has intensified debate regarding its impact on students' academic abilities, while previous studies have not adequately explained the mechanism through which AI use evolves into dependency that shapes academic outcomes. This study aims to examine the effects of AI dependency and the drivers of AI utilization on students' academic impact while proposing a conceptual model explaining their relationships. A quantitative explanatory survey was conducted involving 81 undergraduate students selected through purposive sampling, and the data were analyzed using multiple linear regression. The findings reveal that AI dependency has a positive and significant effect on students' academic impact (β = 0.643, p < 0.001), whereas the drivers of AI utilization have no significant partial effect (p = 0.066). The proposed model explains 57.0% of the variance in academic impact (R² = 0.570). This study contributes by developing a conceptual model demonstrating that academic consequences emerge through the transformation of AI utilization into dependency, which subsequently alters students' learning behavior. Abstrak Perkembangan Artificial Intelligence (AI) di pendidikan tinggi memunculkan perdebatan mengenai dampaknya terhadap kemampuan akademik mahasiswa, sementara penelitian sebelumnya belum menjelaskan mekanisme bagaimana penggunaan AI berkembang menjadi ketergantungan yang memengaruhi aktivitas akademik.
