Abstract

Politeknik Katolik Mangunwijaya (Polteka Mangunwijaya) is a higher education institution formed by the merger of three academies in Semarang. These three academies combined to become popular study programs among the community, offering Diploma III programs in Chemical Engineering, Pharmacy, and Health Analysis. Over time, Politeknik Katolik Mangunwijaya encountered challenges in managing inventory to support organizational effectiveness and decision-making by the structural leadership. To optimize asset management, a web-based inventory information system application was developed. The choice of the web platform was based on its compatibility with all devices. The system was built using the Rapid Application Development (RAD) method with PHP programming language, the Laravel framework, Tailwind CSS, and a MySQL database. This application primarily supports the vice director, superadmin, and program study admins in stock recording, item identification using barcodes, and detailed inventory transaction reporting. This system replaces the manual recording method, which was previously considered inefficient and prone to data loss or inaccuracies. After functional testing and user acceptance, the system has proven to operate smoothly as planned and provides an effective solution for managing inventory at Politeknik Katolik Mangunwijaya.

Abstract

The influence of perceived quality is a classic problem in a vendor selection process. To overcome thisproblem, many algorithms have been used in decision making. In this paper we have carried out theidentification of planning team needs and the optimization of the bidding scheme using key requirements tominimize the influence of quality perceptions. The Kano Model Analysis method, the Analytical HierarchyProcess and Technique for Order Preference by Similarity to the Ideal Solution are used to analyze anddetermine the key requirements in the bidding process for telecommunications equipment needed by theplanning team. Vendor selection based on key of requirements specifications is carried out in six stages,namely the preparation stage, requirements search, selection of Key of Requirements specifications, vendorselection, accuracy testing and conclusions. The results of the analysis show that the need for new planningand architecture of telecommunication service providers can increase to NFVi and services. An importantcriterion for NVFi (Hardware) development is Virtual Infrastructure Management (VIM) with a weight of22%, while the service criteria are Fixed Services with a weight of 50.94%.

Abstract

In today's digital era, most people use smartphones for various purposes. In the laboratory field, as an innovation in laboratory examinations, and as a form of community service to promote healthy living and change people's lifestyles, medical laboratory technicians play a role in creating medical record applications. The development of this application is based on the fact that patients often forget about the examinations they have undergone, making it difficult to accurately record medical history. The examinations conducted on patients are a benchmark for lifestyle patterns that should be carefully considered by patients. This attention begins with the periodic recording of health history, which should be done to anticipate spikes or abnormalities in the body's condition. The application system, created through a semi-automatic method for recording and reminding examinations, is able to minimize errors or inaccuracies in the examination results in the history, thus facilitating self-control of both lifestyle, examinations, and health. Medical record application software can provide health data from previous laboratory examinations and can provide reminders for the next scheduled examination."
