Abstract

UD. TBRK Roastery a private company engaged in the manufacture and sale of local and imported coffee beans. The company was founded in 2016 and the founder of the company is Bowo Sundoro. The center of the company is located at Jalan Manukan Dalam Blok 14 J No. 12 Surabaya. One of the processes is a performance appraisal due to the employee development monitoring mechanism for each period (2 weeks). In conducting the assessment process, problems often occur such as the loss of the performance appraisal file in the previous period or during the ongoing period, the absence of a specific value range at the time of the performance appraisal, the calculation of the assessment which is often wrong, such as a mismatch with the content of the performance appraisal.Based on the problems described above, the solution needed is the creation of a website-based performance appraisal application using a paired comparison method that uses several criteria, including: efficiency, concern, enthusiasm, greeting, ethics, estimation, honesty, completeness, cooperation and passion. Application development uses the system development life cycle (SDLC), which consists of four stages, namely communication, planning, construction, and deployment. The results obtained from this study are in the form of a website-based performance appraisal application using the paired comparison method. This application can perform an appraiser selection process, performance appraisal using paired comparison, namely by performing automatic calculations when the owner or supervisor enters the value into the system. This application generates a performance appraisal report.

Abstract

Efficient energy management in public facilities such as public toilets has become an important challenge in the modern era, especially with the increasing demand for environmental sustainability. In this research, we developed a smart toilet system based on the Internet of Things (IoT) using the ESP32 as the main microcontroller and fuzzy logic methods for intelligent decision-making. This system is equipped with temperature (DHT22), humidity, and distance (HC-SR04) sensors to detect environmental conditions and user presence. Based on this data, the toilet fan and light are automatically controlled to minimize energy consumption. To facilitate real-time monitoring and threshold control, this system is integrated with a Flutter-based application, which provides an intuitive user interface for viewing environmental data and setting temperature, humidity, and distance thresholds. Fuzzy logic is used to determine the fan speed based on temperature and humidity inputs, with the output being a gradual fan speed control. (PWM). The test results show that the system can reduce energy consumption by up to 30% compared to the manual method, especially by reducing the unnecessary device idle time. Additionally, the system has an average response time of 200 ms to send sensor data to the application and receive threshold updates from the user. With this approach, the research shows that the integration of IoT with fuzzy logic provides significant energy efficiency and enhances the user experience. This research also opens up opportunities for further development, such as the integration of machine learning technology for predicting facility usage patterns or the implementation of additional sensors for air quality detection. These findings support the implementation of IoT-based automated systems in public facilities to achieve energy efficiency and environmental sustainability.
