Online learning methods are still the main way to access learning resources. The SPADA UPI platform is essential in supporting the academic and non-academic activities of Universitas Pendidikan Indonesia. In supporting these activities, user experience must also be considered when using online learning platforms. The results of the user experience survey of UPI students stated that all aspects assessed, such as attractiveness, perspicuity, efficiency, dependability, stimulation and novelty, responded poorly. To overcome these problems, it is necessary to redesign the SPADA UPI website to make it an intuitive website. In designing an intuitive website, a design thinking approach is used with output as a prototype of the SPADA UPI website. The User Experience Questionnaire (UEQ) is a user experience evaluation tool that outputs quantitative values. Comparing the UEQ results of the SPADA UPI website and the SPADA UPI website prototype will help determine whether the website prototype design provides a better user experience. The initial UEQ results that have been carried out and compared with the results of the prototype test of the SPADA UPI website show a good increase in value. With initial UEQ results averaging poor or less than 0.8, they improve by providing a score of more than 0.8 or excellent. Therefore, the design thinking approach is beneficial for designing an intuitive product that produces a better user experience.

The quality of pond water is an important factor in ensuring the health and sustainability of the organisms within it. Internet of Things (IoT) technology has enabled the development of sophisticated and effective monitoring systems to monitor water quality in real-time. One important parameter that needs to be monitored is the temperature of the pond water, as unstable temperatures can harm aquatic organisms. To obtain good quality and disease-free fish at normal times, the optimal temperature for catfish fry is around 28˚C - 30˚C. Manual monitoring or using thermometer measuring instruments is still very traditional and limited to the ability of supervisors to carry out continuous monitoring and may cause delays in detecting significant temperature changes. This research aims to analyze the monitoring system of pool water quality based on temperature by utilizing IoT technology. The proposed system uses a DS18B20 temperature sensor that is wirelessly connected to the IoT network. The temperature data collected in real time will be uploaded to Firebase for storage and further analysis. Through the development of this IoT-based pond water quality monitoring system, it is expected to increase efficiency and reliability in monitoring pond water quality. From the monitoring conducted for approximately 24 hours, the temperature in the fishpond is 28°-30°. After analyzing with direct monitoring, the good temperature is at night at 18.00-00.00 WIB. In conjunction with a standard thermometer, resulted in an average temperature sensor error rate of less than 5%, highlighting the reliability of the IoT technology in real-time environmental monitoring.
