Abstract

WiFi performance is a pressing need in academic, especially to support learning, research, and communication. In the digital era, the demand for high network quality is increasing along with the heavy dependence on internet access for various academic activities. Therefore, the evaluation of the WiFi network quality in Jenderal Achmad Yani University is focus of this study, the network meets the required quality standards. This study uses a quantitative method with an observational approach to analyze the Quality of Service (QoS) parameters such as throughput, packet loss, delay, and jitter. The quantitative method was chosen because it is able to provide objective and accurately measured data, while the observational approach allows researchers to directly observe internet traffic and measure QoS parameters. Testing was conducted for three days to obtain representative data on the condition of the WiFi network in the building. From the test results conducted, it is known that the quality of the network in the Faculty of Engineering Achmad Yani University is: Average throughput of 1406.76 Kbps, packet loss of 0%, delay of 70.21 ms, jitter of 85.96 ms. With an average overall index of QoS parameters of 3.25 and included in the Good category according to TIPHON.

Abstract

Conventional coffee roasting methods often face challenges regarding quality inconsistency due to a high reliance on operator proficiency and the absence of precise thermal regulation. This study aims to design and build an automatic coffee roasting system based on the Arduino Uno microcontroller integrated with an SHT-31 sensor for real-time monitoring of steam temperature and humidity. The system applies threshold control logic with a setpoint of 90°C temperature and 12% humidity to automate the servo motor actuator on the gas valve. Operational testing was conducted using coffee bean load variations of 50, 100, 150, and 200 grams. The results showed that increasing bean mass was directly proportional to roasting duration, ranging from 12.46 minutes for a 50-gram load (dark roast) to 21.16 minutes for 200 grams (light roast). Sensor reading accuracy was validated with an error value of 2.62% compared to a standard thermometer. The control system proved effective in stabilizing microclimate parameters and terminating the process automatically upon reaching targets, thereby ensuring final product consistency.

Abstract

The Supervisory Control and Data Acquisition (SCADA) system is essential in pharmaceutical manufacturing, particularly for ensuring product quality and operational continuity in the Water for Injection (WFI) process at the Large Volume Parenteral (LVP) facility of PT Sanbe Farma. This study evaluates the efficiency and performance of SCADA in monitoring and logging WFI flow rate and conductivity. The assessment involves real-time data observation, historical trend analysis, efficiency measurement, and performance evaluation based on data availability, logging reliability, sampling frequency, event detection, and value consistency. Findings show that SCADA achieved 100% data availability for all monitored parameters, with a performance index consistently above 96%, indicating strong capability for real-time anomaly detection and uninterrupted data recording. Flow-rate monitoring efficiency reached 85% in May 2025 but declined to 70% in June 2025 due to process issues. In contrast, conductivity monitoring in both Cold and Hot loops remained highly efficient, exceeding 99%. Statistical results also revealed a 100% variability index and a high peak-to-average ratio, demonstrating the system’s accuracy in capturing dynamic fluctuations. Overall, the SCADA system in PT Sanbe Farma Unit 3 provides reliable monitoring performance and supports early disturbance detection, making it a strong basis for system maintenance and improvement.
