/in /by

This study aims to enhance the quality of the Foley catheter assembly section at PT XYZ, an Indonesian medical device manufacturer, using Six Sigma methodology. PT XYZ currently faces an 8% defect rate in its Foley catheter assembly section, surpassing the acceptable 3% threshold. The current Sigma level of the Shrink process within the assembly section is 2.36, while the Balloon Vulcanizing and Assembly process stands at 2.68. The Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) framework was used to identify and address root causes of defects. Data collection methods included interviews, questionnaires, and field observations, revealing key issues such as incorrect tray loading, machine calibration errors, operator skill variability, and inadequate handling techniques. Proposed improvements include updating Standard Operating Procedures (SOPs), implementing SCAMPER for calibration, comprehensive training programs, and incentive schemes. Additional measures involve template overlays for precise cutting, vendor maintenance, and control charts for consistency. The Control phase ensures sustainability through documentation, training, and monitoring using control charts and Failure Modes and Effects Analysis (FMEA). Implementing these solutions is expected to reduce the defect rate and elevate the Sigma level of both processes to 3, enhancing process efficiency and product quality. This will improve operational efficiency and customer satisfaction, providing a robust framework for PT XYZ to elevate its quality control and contribute to better healthcare device manufacturing in Indonesia.

/in /by

This research aims to develop mathematics learning tools based on Education for Sustainable Development (ESD) using the Outdoor Learning Mathematics method with the goal of enhancing mathematical connections of junior high school students in statistics. The research method employed is a mixed-methods approach combining qualitative and quantitative methods, both conducted through developmental research comprising planning, development, and evaluation stages. The sample for this research was two classes at SMPN 1 Tempeh with homogeneous mathematical abilities, where one class will be used as the experimental group and one class as the control group. Determining the research area using a purposive area sampling technique with the consideration that learning using the outdoor learning mathematics method with educational sustainable development (ESD) based learning tools has never been implemented at SMPN 1 Tempeh. The selection of eighth-grade classes is based on the consideration that statistics material is currently being taught in eighth grade, and eighth-grade students have not been subjects of research for similar studies before.  The learning tools developed are designed in accordance with ESD principles and utilize outdoor mathematics learning approaches to enhance students’ understanding and skills in statistics. The results from Hypothesis Testing for Pretest indicate that a p-value of 0.648 is obtained, where this value > 0.05 means H0 is accepted and H1 is rejected. Therefore, it can be concluded that there is no difference in the mean between the control and experimental groups in the pretest. Whereas the result of Posttest Hypothesis Test indicate that a p-value of 0.028 is obtained, where this value < 0.05 means H0 is rejected and H1 is accepted. So the use of ESD-based mathematics learning tools with the Outdoor Learning Mathematics method is effective in improving students’ mathematical connections in statistics. The implication of this research underscores the importance of integrating mathematics education with sustainable development principles to reinforce students’ understanding and skills in mathematics while also fostering awareness of environmental and social issues.

The research will provide actionable recommendations for PT Pos Indonesia, enabling them to tailor their marketing strategies better through a Marketing 4.0 perspective to meet customer needs and preferences.

Increasing the Adoption of Performance Management Application at PT. Kaltim Prima Coal

/in /by

Traditional performance management systems often suffer from bureaucracy and inefficiency in providing timely feedback and support (Awan et al., 2020). To address these issues, KPC implemented Entomo, a performance management platform with advanced features like goal creation, progress tracking, continuous feedback, and data analytics. This technology-driven approach aims to improve the effectiveness and efficiency of performance management practices. KPC’s Entomo implementation provides an opportunity to research the adoption of performance management system technology. This study evaluates KPC’s experiences, identifies factors with a positive and significant relationship with the application and performance management application, and offers recommendations to enhance the performance management system.

The research employed the technology acceptance model (Davis et al., 1989) and a quantitative approach using questionnaires. Multiple linear regression analysis revealed several important insights. The findings indicate that perceived usefulness, perceived ease of use, and attitude toward using are key determinants of the intention to use the technology or system. Notably, attitude toward using has the strongest influence on users’ intention to adopt and use the system, followed by perceived usefulness and perceived ease of use. The research suggests that organizations should prioritize improving user attitudes, enhancing perceived usefulness, and ensuring the system is easy to use when implementing new performance management applications to drive successful adoption.

Determinants of Sustainable Bond Yield among IDX-Listed Companies

/in /by

This study analyzes the development of sustainable bonds among IDX-listed companies in the post-Covid period of 2022 and identifies the factors influencing sustainable bond yields. The research observes 749 sustainable bonds issued by 93 IDX-listed companies. Multiple regression analysis is employed to explore the relationship between the bond yield as the dependent variable and sustainability factors—Number of Company-Supported SDGs, ESG Risk Ratings, CSR Funds, and GHG Emissions—as independent variables, along with control variables including three bond characteristics (Modified Duration, Issuance Size, Term to Maturity) and eight company characteristics (Board of Commissioners and Directors Diversity, Company Size and Age, ROA, Current Ratio, Industry, State-owned Enterprise status). The findings reveal positive correlations between the Number of Company-Supported SDGs and ESG Risk Ratings with bond yields, while CSR Funds and GHG Emissions show negative correlations with bond yields, indicating complex relationships between sustainability performance and sustainable bond yields. The study results suggest strategic recommendations for companies, investors, policymakers and regulatory bodies, as well as educational institutions to enhance the effectiveness and appeal of sustainable bonds in Indonesia.
