Abstract

Determination of outstanding students is done manually and tends to be subjective. This has shortcomings that cause several problems, namely, it takes a long time and requires energy for manual data processing, then requires extra care and thought in processing student value data. This study aims to produce a decision support system for selecting outstanding students with a matrix normalization process to a scale that can be compared with all existing alternative ratings using ISO 25010 with 8 testing aspects. This development uses the Waterfall model with research steps, namely: 1) Requirement, 2) Design, 3) Implementation, 4) Verification, and 5) Maintenance. In the early stages, researchers seek information related to user needs for the system to be created. Furthermore, the media design is designed based on the results of the needs analysis, after which the media is developed. The final stage is testing. Data collection instruments are conducted through Observation, interviews, and questionnaires. The data analysis technique used is based on the 8 testing characteristics in ISO 25010. The results of the functional suitability aspect test with a result of 98.6% of the criteria "Very Eligible". Performance efficiency testing with a result of 85.2% of the category grade B which is categorized as "Good". Usability testing of the percentage of user responses with a result of 84% of the criteria "Very Good". The results of the compatibility test show that the system has been successfully run on several versions of the browser well and does not cause problems when accessing the system. The results of the security test show that the system has good security with a grade of B. Based on these data, it can be concluded that the system that has been developed has successfully met 8 aspects of testing using ISO 25010.

This study focuses on the development of an Internet of Things (IoT)-based monitoring system designed to measure and control temperature, humidity, and ammonia gas levels in laying hen cages to enhance environmental management efficiency, animal welfare, and productivity. The research employs a Research and Development (R&D) method using a prototyping model conducted at UD. Ayam Ras Petelur, Gowa Regency, Indonesia. The developed system integrates DHT11, and MQ-135 sensors connected to an Android application via NodeMCU ESP8266 and Firebase, enabling real-time monitoring, visualization, and remote access. Through this integration, farmers can instantly obtain environmental data, receive notifications when parameters exceed safe thresholds, and take immediate corrective actions to maintain optimal conditions for the chickens. Evaluation based on the ISO 25010 quality model shows that the system achieves 100% functional suitability and 92.6% usability, which indicates excellent performance and high practicality for end users. Sensor accuracy testing reveals reliability rates of 97.37% for temperature, 97.83% for humidity, and 95.50% for ammonia gas concentration, confirming the system’s precision and consistency in data measurement. The results demonstrate that the IoT-based monitoring system developed in this study is highly feasible, efficient, and accurate for real-time management of poultry cage environments. Overall, this research contributes to the adoption of smart farming technologies in Indonesia’s poultry industry, promoting data-driven decision-making and sustainable livestock management practices.
