<![CDATA[Cats are one of the popular pets kept in Indonesia. On the other hand, there is a potential risk of disease transmission from cats to humans. This research builds an expert system for diagnosing cat diseases based on the symptoms experienced using the forward chaining method. The expert system consists of two main components: the development environment and the consultation environment. In this study, these two components of the expert system are separated into two different platforms. The development environment runs on a website platform, while the consultation environment operates on a Telegram bot platform. System development uses the Expert System Development Life Cycle (ESDLC) development model. This model has six stages, namely, the assessment stage, the knowledge acquisition stage, the design stage, the testing stage, the documentation stage and the maintenance stage. As a result, it assists the general public in performing initial diagnoses of cat diseases.]]>

<![CDATA[Motorcycle users in Indonesia continue to increase every year. This has implications for the increasing need for motorcycle repair or maintenance service providers. This need is an emergency, but this is a problem because the lack of information regarding the location of the nearest workshop makes the process of finding a repair shop consuming a lot of time and energy. This study aims to develop an Online Workshop application that can present a map with the nearest repair shop location using Mapbox and the Geolocation API to make it easier for motorbike users to find a repair shop. In addition, this application allows users to be able to call a mechanic to come to the location. The Bengkel Online application is built using Firebase as a database and applies progressive web apps technology. The results of this study indicate that the online workshop application can be used to order repair services and call a mechanic to the location properly and accurately as indicated by the results of application testing which shows that all features function properly.]]>

<![CDATA[Data access management in web-based applications that use relational databases must be well thought out because the data continues to grow every day. The Relational Database Management System (RDBMS) has a relatively slow access speed because the data is stored on disk. This causes problems with decreased database server performance and slow response times. One strategy to overcome this is to implement caching at the application level. This paper proposed SIMGD framework that models Application Level Caching (ALC) to speed up relational data access in web applications. The ALC strategy maps each controller and model that has access to the database into a node-data in the in-Memory Database (IMDB). Not all node-data can be included in IMDB due to limited capacity. Therefore, the SIMGD framework uses the Euclidean distance calculation method for each node-data with its top access data as a cache replacement policy. Node-data with Euclidean distance closer to their top access data have a high priority to be maintained in the caching server. Simulation results show at the 25KB cache configuration, the SIMGD framework excels in achieving hit ratios compared to the LRU algorithm of 6.46% and 6.01%, respectively.]]>

<![CDATA[Learning media is currently widely used in the teaching and learning process. Technology and information are two things that cannot be separated from one another in the ever-evolving digital era. Likewise with the education sector which underwent a significant transformation. The Learning Management System is a software application for online learning that supports delivering material online, discussing with students, and controlling student performance. This technological advancement has made many tertiary institutions use web application-based information technology. The current problem is the lack of complete features and less interactive functions to support the Learning Management System. In addition, when the user wants to be more interactive in learning, the Learning Management System generally has a separate feature, which requires the user to switch platforms to use the feature. The development of this Learning Management System is expected to become a more interactive learning platform and have complete features compared to other systems. System analysis is done by describing a system as a whole into its component parts. This is intended to identify and evaluate problems that will later find weaknesses and strengths in the system. The method used in this study is the waterfall starting from making the design of the system to implementing the system that runs in a production environment. The results of this study have several features needed for in-person and online learning which generally do not exist in other Learning Management Systems such as video conferencing, docs & files, group chats, automatic check-ins.]]>

<![CDATA[The pandemic that started in 2019 made technology even more important. Accelerating digital adaptation and transformation in the education sector, namely the Learning Management System (LMS) is very helpful in the teaching and learning process. Various LMS platforms are widely used and developed by various agencies. Pradita University is also developing an LMS which is made with the node.js programming language and the next.js framework which can be accessed on the pradita.digital site. The choice of using the wrong technology can cause the problematic LMS that is used to become slow and heavy, to the point where it cannot be accessed. The use of technology with the hypervisior concept which was previously commonly used has various weaknesses. For this reason, the Pradita LMS was developed using container orchestrator technology and Rancher Kubernetes as container orchestrator management. By utilizing Rancher as a container orchestrator management, it can make it easier to use with a user friendly GUI. In this study aims to prove that the use of Rancher in improving the quality and performance of LMS Pradita. Among them by identifying system efficiency, providing better scalability, increasing the availability of Pradita LMS, Rancher is able to manage applications and containers used for Pradita LMS, and saving costs used in implementing physical devices. By using the experimental method applied in this study, the results of system efficiency testing and scalability testing carried out with a load of up to 200 users can run properly and efficiently, then the availability test proves that the LMS is still available even when there are workers who are not operating, and testing rancher management capabilities lead to conclusions Rancher runs optimally and uses resources efficiently in accordance with the objectives in this study.]]>

<![CDATA[Online gaming addiction harms students' physical health, mental well-being and academic performance. The addiction to playing online games has three categories, namely high, moderate and low, which are rarely known by the general public. The significant of knowledge acquisition on the addiction symptom and preventive activities forces the emergence of new idea on expert system identification platform. Therefore, this research aims to develop an expert system using the Backward Chaining (BC) and Certainty Factor (CF) approaches to detect the initial addiction level of online games for university students. Herein, the BC is used to identify the levelling of online game addiction based on the symptoms experienced by the user. There are thirty-three symptoms (G01-G33) provided through the thorough literature reviews and interviews with psychiatrics. Meanwhile, the CF is applied to calculate the level of certainty in determining the possibility of addiction describing in six scale level interpretation. As a result, the application of these two methods has effectively succeeded and reached proper accuracy in identifying the level of addiction of students towards their behavior on playing online games. The comparison of CF testing values between the system calculation and expert judgement shows the sophisticated result. Thus, this research can be utilized by the medical and psychiatric authorities, parents, and students in assessing their symptoms of addiction as an early warning in facing the possible risks arising from online game addiction.]]>
