Abstract

Diabetes mellitus is a chronic non-communicable disease with a steadily increasing prevalence worldwide, posing a significant public health challenge due to its potential for severe complications if not managed properly. In many healthcare facilities, including RSUD Pariaman, there is still no structured system to classify patients according to the severity of their condition, which hampers timely intervention and optimal resource allocation. This study aims to develop and implement a web-based system for clustering the severity levels of type 2 diabetes mellitus using the K-Means Clustering algorithm as a decision support tool for medical staff. A quantitative system development research design was applied, utilizing secondary medical records from January 2023 to December 2024, with five clinical variables: Hemoglobin A1c (HbA1c), Fasting Blood Glucose (GDP), Systolic Blood Pressure (TDS), Diastolic Blood Pressure (TDD), and Body Mass Index (BMI). The system was built using the CodeIgniter PHP framework, MySQL database, and Bootstrap-based interface, following the Knowledge Discovery in Database (KDD) process for data preprocessing. K-Means clustering was configured into three categories (mild, moderate, and severe). Validation using RapidMiner confirmed that the clustering results from the web-based system were consistent with the benchmark model, ensuring the correctness of the algorithm’s implementation. The developed system enables real-time data processing, displays results in both tabular and graphical forms, and provides an intuitive interface for medical personnel, thus supporting clinical decision-making and improving healthcare service quality.

Abstract

Corn is one of the most important food crops in Indonesia, but it is highly susceptible to various diseases that can significantly reduce yield. Diagnosing corn diseases typically requires agricultural experts, whose availability is often limited in rural areas. This research aims to develop an expert system to diagnose corn diseases using the Forward Chaining method. The system was built using PHP and MySQL with the CodeIgniter framework. The methodology included requirement analysis, system design using Unified Modeling Language (UML), implementation, and testing. The knowledge base was obtained from agricultural experts and existing literature, consisting of symptoms, diseases, and their corresponding solutions. Forward Chaining was applied to match user-selected symptoms with predefined rules to produce a diagnosis. The test results indicate that the system can accurately diagnose diseases based on the rules, helping farmers identify problems early and providing recommended solutions without requiring direct expert assistance. This study demonstrates the effectiveness of expert systems in agricultural disease management and offers a potential solution for farmers facing limited access to agricultural experts.
