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 aim of the following research is to obtain empirical evidence regarding the impact of sanctions. taxes, fees obedience taxes, and application e-filing towards compliance WPOP on North Jakarta area. This study applied 100 samples taken from questionnaire data from respondents who live in the North Jakarta area with a sample collection procedure use method non-probability sampling and way purposive sampling. The following research was entered and calculated via the Microsoft Excel program and worked on using the SPSS version 25 program. The research technique used in this research is the Classical Assumption Test & Multiple Regression Analysis Test. The conclusion of this research reveals that sanctions taxation impact positively and significantly above obedience WPOP, fees obedience tax impact negatively and significantly above obedience WPOP, and deployment e-filing impact positively and significantly above obedience WPOP.
