Abstract

This study explores the Product-Service System (PSS) strategy at Akara Space, a coffee shop that adopts a functional results approach to enhance efficiency and business growth. Using a descriptive qualitative method, data were collected through interviews and on-site observations to identify the most suitable PSS quadrants for the business. The findings suggest that Product Pooling, Outsourcing, and Functional Result quadrants are practical strategies. Product Pooling involves resource sharing with other businesses to reduce costs, optimize resource use, and build partnerships. Outsourcing focuses on delegating specific management functions to external providers, enabling Akara Space to maintain service quality while focusing on its core strengths. The Functional Result quadrant introduces a membership model, allowing customers to access services rather than owning products. This approach aligns with customer preferences for convenience and fosters loyalty, creating a steady revenue stream. Implementing these strategies can improve Akara Space’s efficiency, competitiveness, and adaptability in a dynamic market. By leveraging collaboration, resource optimization, and innovative service models, the business can achieve sustainable growth while delivering excellent customer experiences.

Abstract

Efforts to improve services by opening online data access to customers have become straightforward targets for cybercrime. Unfortunately, the researchers' findings reveal that there is presently no cybersecurity framework that completely aligns with the fundamental principles of the retail industry. This paper then analyzes the deployment of cybersecurity frameworks across various industrial sectors to determine which framework—or combination of frameworks—best aligns with the fundamental values of the retail industry. We compare the essential points of each cybersecurity framework with the TWOS Matrix, which represents the core values of the retail industry. We suggest NIST CSF, ISO/IEC 27001:2022, and Essential Eight as the best combination of cybersecurity frameworks for the retail industry. Therefore, the comparative analysis results recommend RCF as a novel framework suitable for implementation in the retail industry.

Abstract

Efforts towards an independent nation with high competitiveness can’t be separated from educational programs. Therefore, education must be able to produce quality graduates who have knowledge, master technology, and have technical skills, and adequate life skills. The timeliness of students in completing their studies is one of the supports for assessing the quality of higher education. Classification analysis can be used to predict whether a student is said to pass on time or not. Support Vector Machine (SVM) and Random Forest methods are part of the classification method. SVM and Random Forest classification analysis is done by using historical data alumni from FMIPA UNM of the graduation year 2019-2020 which come from the Administration, Academic and Student Affair Bureau of UNM. SVM accuracy level of RBF kernel with optimum value C = 1 and gamma = 1 is 68% and Random Forest accuracy with optimum value m = 2 and k = 500 is 72%. Therefore, the best method for determining the accuracy of the study duration of FMIPA UNM students is Random Forest..

Abstract

This study examines the implementation of the 5S work culture in PT XYZ International, focusing on the roles of leadership commitment and employee involvement in enhancing business performance. The 5S principles—sorting, organizing, cleaning, standardizing, and sustaining discipline—are analyzed to identify critical factors influencing their effectiveness. Using Structural Equation Modeling-Partial Least Squares (SEM-PLS), data were collected from 100 respondents through questionnaires and analyzed to evaluate relationships between variables. The results indicate that leadership commitment and employee involvement significantly influence the implementation of the 5S work culture, accounting for 33.1% of the variation in business performance. However, suboptimal employee adherence to 5S principles remains a challenge, impacting the overall effectiveness of the work culture. Key findings highlight areas for improvement in technical and social aspects, with actionable recommendations proposed to enhance 5S implementation and business outcomes. This study contributes to understanding the integration of 5S principles in Indonesian manufacturing companies and offers insights for similar organizations aiming to optimize their operational efficiency.

Abstract

East Kalimantan has great potential as a food production center in Indonesia, supported by the Sebakung Swamp Irrigation Area (DIR) which covers an area of ​​13,500 hectares with a functional area of ​​10,290 hectares. However, inefficient irrigation management and inadequate infrastructure maintenance have resulted in suboptimal land use and decreased agricultural productivity. This study aims to analyze the performance of the existing irrigation network and determine the budget required for its operation and maintenance. The study was conducted using field observations and regulatory guidelines, including Ministerial Regulation No. 12/PRT/M/2015 and No. 23/PRT/M/2017. The results of the study indicate that most irrigation channels are below Index 3, indicating significant sedimentation and vegetation growth that inhibits water flow. The overall channel condition index is 2.10 with a network functional level of 72.50%, while several water gates in certain villages are severely damaged with an Index classification of 4. The total operational cost of managing the irrigation network is IDR 292,300,000.00 which includes personnel incentives, monitoring, office operations, and equipment maintenance. Routine and periodic maintenance costs vary, with the highest budget allocated to Sri Raharja and Babulu Laut, totaling more than IDR 187,200,000.00. To improve irrigation performance, systematic management strategies such as routine dredging, vegetation control, and rehabilitation of priority infrastructure must be implemented. These efforts will improve irrigation efficiency, ensure optimal water distribution, and support agricultural productivity in East Kalimantan.
