Abstract

This study aims to build a library system application that can be used in the library of the Faculty of Engineering UNTAG Semarang based on an RFID card. From the background of the problem, namely, the process of borrowing and returning books is quite long, because to search for borrowed books the librarian must go to the bookshelf and look for the title of the book to be borrowed. The difficulty in making reports, because it is done after the library activities are finished, does not automatically coincide with the process of borrowing and returning services. Starting from the problems above, and paying attention to the number of daily visitors in the library that must be served, the authors propose to create a library service application using an RFID tag that can help the process of searching for member data and library books quickly.

Abstract

The results of this study are in the form of a product, namely an android application, an ordering and payment system using Android-based QR Code technology. According to the research design, the research results go through two testing or validation processes, namely design validation by experts in this case expert lecturers in the computer field, and product validation by users.Validation is carried out using an assessment instrument in the form of a questionnaire or validation sheet. The questionnaire contains 10 questions that must be filled in with a value between 1 and 4. The total score will get a score of not good, enough, good, or very good. The final conclusion is a statement that the product must be replaced, can be used with many revisions, can be used with few revisions, or can be used without revision.The results of the design validation test by experts gave a total score of 37, included in the score indicator 31 n 40, namely "Very Good". The conclusion drawn by the expert for system design is "Can be Used Without Revision".The results of product validation testing by users give an average value of 35 so that it is in the indicator category and gets the "Very Good" predicate. The final conclusion of user validation is a product or prototype "Can Be Used Without Revision".This research was conducted in a restaurant, Restaurant isn’t just a place to eat something but also a place to relaxing, meet someone or hang out with friends or colagues. Service of the restaurant is the main factor to make customer feel comfortable and relax. Many restaurant make their own order and payment system for better service but they forgot about the speed of their services.Using research methods data collection, observation, and interviewin Kedai Cangkir Gubug, face to face service like greeting, take order, and serving order all of it is waiter’s job. All of that tasks need time at most that makes if the restaurant have many customers, every single customer have to wait for a longer time waiting for waiter that serving another customer. The payment method is quite troublesome for customer because they have to save order paper for payment in cashier later.The solution that writer’s made is to decrease the task of waiter so that services can be done equally with QRcode technology for ordering menu with the scanner is android smartphone. Payment only need name of customer or table number and customer can do it in cashier or they can request the bill at their table. Therefore waiter no need to take order one after another and customer can do payment easier.

Abstract

Analysis of E-Learning Information Systems is certainly one of the efforts that can be made to overcome problems that arise in the process of implementing teaching and learning activities (KBM) in each school. Soft System Methodology (SSM) analysis is a method used to help model unstructured problems. The SSM methodology is suitable for assisting an organization in defining their goals and then building a human activity system to achieve those goals. The relationship between the internal and external academic community involves teachers, parents of students, students and school administrators to develop information for supervision and student Development approaches. E-Learning analysis using the Soft Systems Methodology (SSM) approach is expected that the E-Learning information system will be able to answer existing challenges and problems. This study carried out a CATWOE analysis of the holons and elements (Client, Actor, Transformation, World View, Owner, Environment) found in case studies, building E-Learning models by applying the roles of humans, processes and technology as knowledge-forming elements, then analysis. holons based on the modeling of the resulting Knowledge. The analysis of E-Learning needs is answered by the need between the internal staff of teachers, employees, counseling and external students and parents to improve the quality of teaching and learning activities and student development.

Abstract

This research aims to identify the issues faced by one of the paint distributors in managing their sales information system. The study notes that despite the store's successful sales activities, the utilization of the sales information system remains limited, with the store preferring to manage products without online information handling applications. Based on observations, some weaknesses of the current system include lack of stock data accuracy, hindrances in providing real-time stock information, and limitations in tracking stock changes. The author suggests providing training to users of the web-based sales information system and establishing clear task allocation, as well as system improvements to address existing weaknesses. These suggestions are expected to enhance efficiency and effectiveness in sales management and meet the needs of both administrators and buyers.

Abstract

This study aims to improve the transparency of machine learning models in credit scoring using various Explainable Artificial Intelligence (XAI) methods. The methods used include SHAP, BRCG, ALE, Anchor, and ProtoDash to explain the prediction results of machine learning models, namely logistic regression, XGBoost, and random forest. This study applies a quantitative approach with a comparative method, where Ceria loan application data from Bank Rakyat Indonesia (BRI) is analyzed using a machine learning model, then evaluated using the Explanation Consistency Framework (ECF). The results show that the XAI method can improve understanding of model decisions, with SHAP and ALE effective for global explanations, while Anchor and ProtoDash provide in-depth insights at the individual level. Evaluation using ECF shows that the post-hoc method has high consistency, although Anchor has limitations in the aspect of axiom identity. In conclusion, the XAI method can help improve trust and transparency in credit scoring at BRI.Keywords: Explainable Artificial Intelligence; Credit Scoring; Machine Learning; Model Interpretability; Explanation Consistency Framework AbstrakPenelitian ini bertujuan untuk meningkatkan transparansi model pembelajaran mesin dalam penilaian kredit menggunakan berbagai metode Explainable Artificial Intelligence (XAI).
