Abstract

This study aims to analyze the influence of academic, family, and learning environment factors on student exam scores. The study employs a quantitative approach using secondary data in the form of the Student Performance Factors dateset comprising 6,607 observations. The dependent variable in this study is student exam scores (Exam_Score) [1], while the independent variables include study hours (Hours_Studied), attendance (Attendance), previous scores (Previous_Scores), tutoring sessions (Tutoring_Sessions), parental involvement (Parental_Involvement), and access to learning resources (Access_to_Resources) . The analytical techniques used were descriptive statistics and multiple linear regression. The results indicate that the regression model is statistically significant simultaneously with an F-value of 1,601 and p < 0.001, and explains 66.0% of the variation in students’ exam scores (R² = 0.660). Partially, study hours, attendance, previous scores, and tutoring sessions have a positive and significant effect on test scores. Additionally, students with higher levels of parental involvement and access to learning resources tend to achieve better test scores [2] . These findings indicate that students’ academic achievement is not solely determined by individual study effort but is also influenced by family support and the availability of an adequate learning environment.

Abstract

The development of industries based on digital technology requires vocational high school (SMK) graduates not only to have technical competencies but also strong soft skills, particularly in technology leadership (tech leadership). Students majoring in Computer and Network Engineering (TKJ) need to be equipped with communication skills, teamwork, problem-solving, and decision-making abilities to be able to adapt and compete in a dynamic industrial world. This community service activity aims to improve the competencies of SMK Gelora Jaya Nusantara students through Soft Skills Tech Leaders training as an effort to prepare them for the challenges of the workforce. The implementation methods include interactive workshops, group discussions, case study simulations, and learning reflections. The results of the activity show an increase in students' understanding of the roles and responsibilities of a tech leader and the importance of soft skills in managing technology projects. Participants showed high enthusiasm and active involvement throughout the training. This activity is expected to serve as a strategic step in supporting the readiness of the younger generation to face digital transformation and the demands of Industry 4.0.

Abstract

Currently, Coffee Hitam Putih still uses manual recording. Manual order recording is less efficient in terms of time and cost. So, to realize consumer satisfaction in ordering food, a food/beverage ordering information system on web-based Coffee Hitam Putih was created. This information system provides a list of food menus, prices, descriptions, and availability. This information system makes it easier for the management of Coffee Hitam Putih to provide effective and efficient services. It can produce fast, precise and accurate information because it uses a database. The methods used in data collection are: a. Literature method, which is a method of collecting data with the help of books from the library or documents and reports related to this research. b. The observation method, which is observing the running system directly on the object to be studied, in order to provide clear and precise information about the process and activities related to ordering menus at Coffee Hitam Putih. c. Interview method, namely conducting questions and answers directly with the manager of Coffee Hitam Putih. The advantage of this technological development is that it is very helpful for people's daily activities. The existence and role of information technology in all sectors of life have an impact on the economic, social, and cultural aspects of human beings.

Abstract

Human capital is a key factor in realizing an organization’s vision and mission. To ensure optimal performance, employee output must be evaluated consistently through a well-organized appraisal process. Although PT Kompas Media Nusantara has adopted such evaluations, they are still carried out using traditional methods, such as distributing physical documents. To address these inefficiencies, an ERP-based Employee Performance Evaluation System has been designed to streamline workflows, enhance accessibility, and support a more standardized and systematic assessment process. This system utilizes Key Performance Indicators (KPIs) aligned with individual job responsibilities to measure performance. The development process adopts the Scrum methodology, while system validation is carried out through Black Box Testing. The test results reveal that the system performs reliably, achieving a 100% accuracy rate in matching inputs and expected outputs. To assess user satisfaction, the End User Computing Satisfaction (EUCS) framework combined with a Likert scale was employed. The evaluation produced high satisfaction scores across various dimensions: content (89.12%), accuracy (87.02%), layout and design (88.07%), user-friendliness (89.12%), and timeliness (86.84%). These findings indicate strong user acceptance of the ERP-based system, reinforced by consistently positive user feedback regarding its effectiveness and ease of use

Abstract

Toko Anarman Store is a toy store that sells various kinds of toys, education, and home decor. This shop still uses a manual system for sales transactions, with the process of selling goods usually still written on notes and then summarized in a sales book. The seller must check each item individually and record the results in a book to determine the number of items in the store. Therefore this web-based Sales Information System is designed to assist the sales process at the store. The purpose of this system is to increase the efficiency and effectiveness of the sales process. This system includes several important features which include product management, supplier management, and report printing.

This information system is made using the Sublime Text 3 application while the programming language uses PHP, Xampp is used to run the web server, MySQL is used for database management. With this system, it is hoped that Anarman Store can improve operational efficiency and increase customer satisfaction. This system can also help in making better decisions based on accurate sales data.
