Abstract

This research presents the development of an Android-based Industrial Internship Management System for the Industrial Electronics Department at SMK Negeri 1 West Cikarang. The study addresses the inefficiencies in manual internship administration by implementing a digital solution using the Waterfall methodology. The application was developed using Dart programming language and Flutter framework to ensure cross-platform compatibility and responsive user interface. The system features include student registration, internship placement tracking, supervisor assignment, performance evaluation, and reporting functionalities. Testing results demonstrate significant improvements in information accessibility, communication efficiency, and administrative workflow. This application effectively bridges the communication gap between students, teachers, and industry partners while streamlining the documentation process. The implementation shows potential for adaptation in similar vocational education settings requiring structured internship management solutions.

Abstract

Limited understanding among cat owners regarding skin diseases in cats can have significant implications for the well-being of both cats and humans in the future. Certain skin conditions in cats are not confined to the animals themselves but can be transmitted to humans and other animals. To address such challenges, the development of an expert system for diagnosing skin diseases in cats is proposed. The study was conducted at Cat’s Petshop and Animal Clinic in Grand Depok City. Data were gathered through interviews with Drh. Atiek and Drh. Zeta, veterinarians at the location. The interviews identified six prevalent types of skin diseases in cats. Key issues include the manual recording system at the clinic, lengthy examination queues due to veterinarians’ packed schedules, and the limited knowledge of pet owners regarding symptoms of skin diseases in cats, which delays the diagnostic process. A solution was implemented by designing an expert system for diagnosing skin diseases in cats using the certainty factor method, which quantifies the confidence level of experts in their diagnoses. The application assists cat owners in identifying the type of skin condition affecting their pets. The certainty factor method enhances accuracy by accounting for uncertainty in calculations. The expert system yields positive outcomes. Primarily, it accelerates the examination of skin diseases in cats at Cat’s Petshop Depok. Additionally, it improves the precision of preliminary diagnoses. The deployment of the application saves time for pet owners and reduces waiting times at the clinic. The diagnostic accuracy aligns with the certainty factor calculation approach, addressing uncertainties in results. Overall, the expert system employing the certainty factor method offers an effective solution to overcome the lack of understanding among cat owners about skin diseases. The application facilitates early symptom recognition, enhances time efficiency, and improves diagnostic precision.

Abstract

The Maneungteung Tourism Area in Cirebon Regency holds strong potential as a local attraction, yet the absence of an integrated information system limits visitor access to reliable tourism data. This study aims to develop an Android-based Geographic Information System (GIS) integrated with Location-Based Service (LBS) technology to enhance information accessibility, spatial accuracy, and management efficiency. The research employs the Agile Software Development approach using the Extreme Programming (XP) model, which emphasizes flexibility, iterative improvement, and continuous collaboration between developers and users. The system was built using Android Studio with Java as the main language, integrating Google Maps API for real-time spatial visualization and Firebase for database management and authentication. Functional and user acceptance testing demonstrated that the application runs reliably, displaying accurate destination information, navigation routes, and booking features. Administrators can manage data dynamically through a synchronized backend system. The integration of GIS and LBS technologies successfully improves tourism service delivery, promotes user engagement, and supports the digital transformation of tourism management in Cirebon Regency, particularly in the Maneungteung area.
