Abstract

This study aims to estimate the average coffee consumption of Pamulang University students using the point estimate and confidence interval methods. The research employed a descriptive quantitative approach using primary data collected through an online questionnaire distributed to active students of the Informatics Engineering Study Program. The analyzed variable was weekly coffee consumption measured in cups. Data analysis was conducted using descriptive statistics to obtain the mean, median, mode, and standard deviation. The point estimate method was applied to obtain a single estimated value of average coffee consumption, while the confidence interval method was used to determine the population mean range with a 95% confidence level. The results indicate that the average coffee consumption of Pamulang University students is 4.5 cups per week. The 95% confidence interval shows that the population mean lies between 3.60 and 5.40 cups per week. These findings provide an objective statistical description of students’ coffee consumption patterns and may serve as a reference for further research related to student lifestyle and health.

Abstract

The rapid development of information systems has permeated corporate management, including at PT Petrindo Semesta, an oil and gas industry supply and maintenance company with high sales visit activity. Currently, the management and reporting of sales visits, which still rely on a manual logbook, pose significant constraints, such as difficulty for HRD in compiling visit hours, inefficient logbook access for sales personnel, and insufficient monitoring of visit outcomes. Therefore, this research aims to design and build a web-based sales visit report system using the Rapid Application Development (RAD) method, which is expected to simplify the recording of check-in and check-out times for HRD, provide easier logbook access, and facilitate report monitoring by supervisors, thereby making the recapitulation process more systematic, logbook access easier, and reports effectively actionable.

Abstract

This study aims to classify images of traditional Indonesian foods using the Convolutional Neural Network (CNN) algorithm. Image-based food classification plays an important role in the development of visual recognition systems, particularly in the fields of food technology and artificial intelligence. The dataset used in this study consists of several classes of Indonesian foods obtained from open sources and categorized based on food types. The research process includes data collection, image preprocessing, CNN model training, and performance evaluation using accuracy metrics. The experimental results show that the CNN algorithm is able to classify Indonesian food images with good accuracy. This study is expected to serve as a foundation for the development of automatic food classification systems and to support the application of image processing technology in the Indonesian culinary field.

Abstract

Sleep quality is an important factor that influences an individual's psychological condition, especially stress levels. Problems with poor quality sleep can trigger increased stress and reduce an individual's ability to carry out daily activities. This research aims to determine the relationship and influence of sleep quality on stress levels. The research method used is a quantitative approach with the Spearman correlation method. The research subjects consisted of 50 respondents. Data collection was carried out through sleep quality questionnaires and stress scales which were distributed online using Google Forms. Data analysis includes Spearman's correlation test, descriptive statistics and regression tests. The results of the Spearman correlation test show that there is a significant relationship between sleep quality and stress levels with a correlation coefficient value of r = 0.451 and a significance value of p < 0.001, which is included in the moderate relationship category. The results of descriptive statistics show an average value of sleep quality of 17.34 and stress level of 17.62. The regression test shows that sleep quality contributes 14.9% to stress levels and has a significant effect. This research concludes that quality sleep can be an effort to reduce stress.

Abstract

This web-based employee attendance system was developed to optimize the efficiency and accuracy of attendance recording at CV Azzara Gemilang, which was previously done manually. The system was created using the PHP programming language and MySQL database, by implementing the Waterfall development model which includes the needs analysis, design, implementation, and testing stages. The results of its implementation show the system's ability to automate the attendance recording process, store data centrally, and produce fast and accurate reports. Testing with the Black Box Testing method confirms that all the key features are operating properly according to the user's needs.

Abstract

In this case, this study is conducted to see the level of usability of the Mentari UNPAM e-learning application with the System Usability Scale (SUS) method. As more and more people embrace virtual learning, the quality of a user interface and a user experience becomes an integral component in gauging an e-learning system’s effectiveness relative to ease of use, efficiency, and overall user satisfaction (usability). This method, SUS, was chosen due to its quantitative nature, simplicity, and common use as a global yardstick in empirical investigations of information systems and e-learning. Respondents in this study are active student users of the Mentari UNPAM platform. Data were collected from a 10-item SUS questionnaire and analyzed to obtain the average SUS score as a reference for system user acceptance. This indicates that the average SUS score of the Mentari UNPAM application lies in the category of above average/good (if > 68) and below average (if < 68) based on the standard interpretation of SUS. These results show that even with active use of the system, several areas need to be developed: learnability, the consistency of the interface, and the coupling of functions. The implications of this study recommend the improvement of the e-learning system through improvement of the user interface, training of users, and evaluation.

Abstract

Stress is a psychological response that arises when individuals face demands exceeding their adaptive capacity. University students are considered a vulnerable group to stress due to academic demands, social pressure, and adjustment to the higher education environment. This study aims to estimate the proportion of students experiencing high stress levels using an inferential statistical approach. This research employed a quantitative method with a survey design. Data were collected through a stress-level questionnaire distributed to student respondents. The questionnaire results were classified into stress categories, namely low, moderate, and high. Data analysis was conducted by estimating the proportion of students with high stress levels and determining the confidence interval to describe the accuracy of the population estimation. The results indicate that a certain proportion of students experience high stress levels within the specified confidence interval. These findings suggest that academic stress among students is a significant issue that requires attention. The results of this study are expected to serve as a reference for higher education institutions in developing stress prevention and management programs to support students’ mental health.
