Abstract

Computer computer-based information systems at an institution are often built in stages and separately. Data integration between subsystems is not well connected. The results in differences in the data structures or the number of records between one subsystem and another so that the data presented is not aligned. This study aims to design and implement a RESTful Web Service so that other information subsystems can use employee data from the Management Information System. The four stages in this research are observing the information system currently running, analyzing the data integration needs, designing and coding the RESTful Web Service API, implementing and testing the response time.

Abstract

This study developed a predictive model based on Random Forest algorithm to predict survival rate of Vannamei shrimp using five water quality parameters: dissolved oxygen (DO), temperature, pH, salinity, and Total Dissolved Solids (TDS). The model was trained on this data and evaluated using Mean Squared Error (MSE) and R² Score, with an MSE of 0.71 and R² Score of 1.00. Endpoint testing was conducted using Postman to verify the model response, with output parameters including anomaly_detected, recommendation, and survival rate. The model successfully detected anomalous conditions and provided recommendations according to the detected water quality parameters. Test results showed that DO and salinity had the greatest influence on survival rate, while pH, TDS, and temperature made moderate contributions.
