Abstract

This Paper described design a fuzzy logic-based temperature control system for Paint Protection Film (PPF) installation workshop spaces. PPF installation requires optimal temperature conditions (20-27°C) to ensure proper adhesion, but workshop environments often experience temperature fluctuations that compromise installation quality. The research method uses computational simulation with a modified Mamdani fuzzy logic approach, incorporating more aggressive membership functions, adaptive aggression factors, and integral control. Simulation was conducted with a setpoint of 20°C, initial temperature of 30°C, and duration of 30 minutes. Results show the system successfully achieved a steady-state error of 1.491°C, overshoot of 45.14%, and settling time of 30.0 minutes, meeting validation criteria with steady-state error < 1.5°C. The system maintained temperature within the manufacturer-recommended range for PPF installation. The research concludes that modified fuzzy logic control strategies effectively enhance system performance for specific PPF workshop applications. The main contribution is the development of a control system tailored to the specific requirements of PPF workshop environments, filling a research gap in intelligent control system applications for this context.

Abstract

The rapid development of the Internet of Things (IoT) has increased the demand for wireless communication systems that are fast, efficient, and independent of internet network infrastructure. This study aims to implement the ESP-NOW protocol in a multi-sensor monitoring system using ESP32 as the data transmitter and ESP8266 as the data receiver. The system was designed to acquire temperature and humidity data using a DHT11 sensor and distance data using an HC-SR04 sensor, which were then transmitted in real time through ESP-NOW communication. On the receiver side, the data were displayed on a 16×2 LCD and Serial Monitor, while packet loss was calculated using the sequence number method. An experimental approach was employed to evaluate communication performance based on temperature, humidity, distance, received packets, lost packets, and packet loss percentage. The results showed that the DHT11 sensor produced an average temperature of 29.82°C and an average humidity of 75.1%, while the HC-SR04 sensor achieved a measurement error of less than 2%. Communication testing was conducted over five cycles with 100 samples per cycle. The first three cycles recorded 0% packet loss, whereas the fourth and fifth cycles experienced packet losses of 32.34% and 62.12%, respectively. The average packet loss obtained was 18.89%. The findings indicate that ESP-NOW is capable of supporting real-time multi-sensor data communication without requiring an access point or internet connection, although communication quality is influenced by distance, physical obstacles, and signal interference. The developed system demonstrates potential for deployment in various IoT-based monitoring and automation applications.

Abstract

Differentiated instruction has become a key pedagogical approach within Indonesia's Merdeka Curriculum. However, empirical evidence explaining how it is systematically implemented in vocational Economics classrooms remains limited. This study aims to analyze the planning, implementation, and evaluation of differentiated instruction in Grade X Economics learning at SMK Raudlatul Ulum Ledokombo Jember. Unlike previous studies that primarily emphasize instructional effectiveness or teachers' readiness, this study proposes a process-oriented perspective by conceptualizing differentiated instruction as an integrated pedagogical framework linking diagnostic assessment, adaptive instruction, and authentic assessment. The findings identify three interconnected dimensions that shape effective differentiated learning implementation. This study employed a descriptive qualitative approach using a single-case study design. The research involved 14 purposively selected informants, comprising one principal, one vice principal for curriculum, one Economics teacher, and eleven Grade X students. Data were collected through classroom observations, semi-structured interviews, and document analysis, and analyzed using an interactive model of data condensation, data display, and conclusion drawing supported by source triangulation to ensure credibility. The findings reveal that differentiated instruction was implemented through three integrated stages: (1) diagnostic assessment-informed instructional planning, (2) adaptive classroom implementation involving differentiated content, process, and product, and (3) continuous formative assessment supported by authentic feedback and flexible learning products. These findings demonstrate that the effectiveness of differentiated instruction depends on the coherence between planning, instructional adaptation, and assessment rather than on isolated teaching strategies. The study contributes to strengthening the conceptual understanding of differentiated instruction as a holistic pedagogical process within vocational Economics education.
