Abstract

Phytopharmaceutical plants have become one of the main commodities contributing significantly to the economy through their use in the pharmaceutical, cosmetic, and health industries. However, behind this economic potential, traditional herbal medicine businesses often face challenges, particularly in promotion and brand identity. Social media platforms like Instagram have now introduced unique features to support business and marketing, primarily by providing in-depth information about herbal products and offering opportunities for businesses to receive feedback from consumers. Comments on social media are valuable but often unstructured; hence, sentiment analysis is necessary to organize and categorize this data. By combining comment data with information from Google Trends, cause-and-effect relationships from comments during specific periods can be identified using path analysis. This research aims to analyze consumer comments on the Sidomuncul company's Instagram platform, with the hope of benefiting the company and advancing herbal medicine products. The methods used in this study include Artificial Neural Network (ANN) and K-nearest neighbor (KNN) to classify comments into positive, negative, and neutral categories. Both methods show satisfactory results in classification, with an average accuracy of 0.887 for ANN and 0.874 for KNN. However, the ROC curve for the KNN model indicates a relatively low AUC value in classifying negative comments, at 0.598.

Abstract

This study delves into the multifaceted dynamics influencing leadership succession and sustainability in family businesses, focusing on key variables such as intergenerational cooperation, family relationships, intrinsic motivation of successors, the controlling generation, and the presence of good governance. Employing a comprehensive literature review methodology, relevant academic sources were analyzed to construct a conceptual model that synthesizes theoretical and empirical insights. The findings highlight the essential role of strong intergenerational collaboration and robust governance structures in promoting smooth succession and long-term business viability. However, inherent challenges such as generational conflicts and lack of formalized succession plans pose risks to continuity. This study contributes a framework that underscores the importance of balancing familial values with strategic business objectives to sustain family firms across generations.

Abstract

Kantor Sistem Informasi Universitas Atma Jaya Yogyakarta merupakan unit pendukung universitas dengan tujuan untuk mendukung tugas manajemen sistem informasi dalam ruang lingkup Universitas Atma Jaya Yogyakarta. Kantor Sistem Informasi memiliki sebuah sistem pengelolaan presensi mahasiswa yang belum terintegrasi dengan MBKM sehingga kurang sesuai dengan tujuan sistem, dan teknologi yang kurang mendukung proses pengembangan di masa depan. Sistem pengelolaan presensi mahasiswa pada penelitian ini diharapkan dapat menyelesaikan masalah tersebut. Hal ini diharapkan dapat memudahkan dosen atau pengguna lain dalam mengakses kegiatan yang berkaitan dengan mahasiswa. Terdapat tiga jalan yang dapat digunakan dalam proses manajemen kehadiran mahasiswa. Jalan tersebut antara lain jenis manipulasi secara manual, berkas Teams, atau Moodle. Fungsi ini diharapkan dapat memudahkan dosen dalam memasukkan kehadiran mahasiswa, terutama dalam pertemuan secara online. Sistem ini juga mendukung manipulasi pertemuan kelas, yang meliputi pertemuan pengganti dan materi pertemuan. Fitur yang disediakan diharapkan dapat memenuhi kebutuhan pengelolaan presensi mahasiswa Universitas Atma Jaya Yogyakarta.   Information Systems Office of Atma Jaya Yogyakarta University is a supporting unit of the university with the sole purpose for assisting and managing numerous other information systems in Atma Jaya Yogyakarta University. The office currently has a student management system that has not yet integrated with MBKM program, therefore it does not align with the system’s intended purpose for the university and lacks foundation or support for future development. The student management system in this study helps to correct said problems. This system aims to help lecturers managing student-related activities. There are three viable ways to record student’s attendance: manual entry, imported attendance file from Microsoft Teams, or attendance file from Moodle. This feature designed to simplify the recording process of student’s attendance especially during online classes. Furthermore, this system could also manage class meetings, which consists of substitute classes and learning materials. The provided functionalities are expected to meet the needs of student’s attendance management at Atma Jaya Yogyakarta University.

Abstract

The abstract contains a brief description of the Purpose: This study investigates the effect of facilities and infrastructure management and the completeness of learning facilities on student loyalty, with student satisfaction as a mediating variable based on Expectation Disconfirmation Theory. Methods: A quantitative explanatory survey was conducted involving 80 students of a private junior high school in Samarinda, Indonesia, selected through purposive sampling. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS 4. Results: The findings show that facilities and infrastructure management and learning facilities significantly influence student satisfaction, while student satisfaction has a strong effect on student loyalty. The direct effects of facilities and learning facilities on loyalty are not significant, indicating that student satisfaction fully mediates these relationships. Implications: The study highlights that student loyalty is formed through satisfaction rather than direct facility provision, suggesting that schools should focus on improving students’ perceived satisfaction through effective facility management and utilization.

Abstract

Background. PT Rentang Buana Niagamakmur is a spring mattress manufacturing company that faces a decrease in productivity due to worker discomfort and ergonomically suboptimal working postures Purpose. This study aims to identify the causes of workers' physical discomfort in the production process and design work aids that can improve comfort and productivity. Method. The research process began with data collection through observation and interviews to understand the activities of workers at the production station. The Nordic Body Map (NBM) was employed to identify workers’ musculoskeletal complaints, while Rapid Entire Body Assessment (REBA) was applied to evaluate ergonomic risk levels. Results. Based on the results of the analysis, the design of work aids was carried out using an ergonomic approach that suits the needs of workers at fabric measurement and foam cutting stations. Evaluation of the effectiveness of the aids was carried out by comparing REBA scores before and after the use of the aids. Conclusion. The results showed that the main physical complaints of workers were identified in the right wrist, waist, and calf. The design of work aids at the fabric measuring station lowered the REBA score from 11 to 3 (low risk), while the aids at the foam cutting station reduced the score from 7 to 3 (low risk). Implementation. The proposed work aids were shown to significantly reduce physical discomfort and improve productivity at both workstations.
