Abstract

In this study, we present the validation of the AFCI (Analysis and Identification, Find Color, Color Composition, and Implementation) model as a problem-based approach to enhance the quality of multicolor output in open and distance learning materials. The primary objective was to evaluate the reliability and validity of the AFCI model, specifically designed to incorporate two-color separation techniques aimed at reducing costs while improving the quality of multicolor content. Our research encompassed the examination of printed modules and samples across diverse subject areas, including Basic Chemistry, Architecture, Enterprise System Design, and Teacher Profession. To establish the validity of the AFCI model, a comprehensive validation process was conducted, involving focused group discussions with experts specializing in graphic design, printing, and educational materials. The outcomes of this rigorous validation process revealed substantial validity coefficients (rα visibility = 0.98, rα attractiveness = 0.97, rα convenience = 0.91, rα emphasis = 1), affirming the model's effectiveness. Furthermore, the internal consistency of the AFCI model was confirmed with a Cronbach's Alpha coefficient of 0.86. This research significantly contributes to the realm of open and distance learning by introducing an innovative model for improving multicolor content quality. The AFCI model's successful validation underscores its potential to benefit practitioners and educators in developing high-quality teaching materials, thereby enhancing the overall learning experience in open and distance education.

With the rapid development of information systems, of course it encourages the Open University to adopt an e-supply chain system to increase efficiency and effectiveness in supply chain management. However, e-supply chain implementation does not always run smoothly and often faces various obstacles that affect organizational performance. This research aims to identify problems that occur in the e-supply chain business process during printed teaching material services for UT students and provide recommendations for improvements that can improve the performance of the management system. The research method used is to use a qualitative approach and collect data and information through group discussion forum activities between UT and partners, in this case Partner Companies in Printing and KG Express as service partners for sending UT printed teaching materials to students, as well as analyzing company documents and direct observation of operational processes. The research results show that there are several main obstacles in the e-supply chain process, including: cases of sending packages of printed teaching materials that are mixed up, cases of packages being lost during the process of sending packages of printed teaching materials, and miss routes not reaching student. Based on the analysis of the findings, the research recommends several improvements, including proposals for a new e-supply chain process network, and business processes requiring BAC UT settings. Implementation of these recommendations is expected to increase the efficiency, effectiveness and reliability of the e-supply chain system in UT BAC delivery services to students in the future.Keywords: Recommendations, Business Processes, E-Supply Chain, Printed Teaching Material Services.

Abstract

Airfoil is a cross section from air plane wings can affect aerodynamic performance to lift force (FL). The lift force generated by airfoil has different values due to several external and internal factors, including angle of attack, flow rate and camber. To find the lift force of airfoils with different cambers and variations angle of attack and then flow rate can use computational fluid dynamics simulation. Computational fluid dynamics is simulation on a computer that can complete systems for fluid, heat transfer and other physical processes. This research using computational fluid dynamics simulation performed by SolidWorks, with NACA airfoil type which has different camber NACA 0012, NACA 4612 and NACA 6612. The angle of attack used in research was 0o, 4o, 8o, 12o, 16o and 20o. Flow rate used in research was 20m/s, 40 m/s, 60 m/s, 80 m/s and 100 m/s. From this research will be the bigger camber can produce a greater force lift. In addition, the greater airfoil flow rate can produce a greater force lift. This research also that the connection between force lift with coefficient lift (CL) is nonlinear quadratic form.
