This study aims to explore the teacher's role in the process of implementing the Independent Curriculum which has been implemented nationally through central government policies. In its implementation, the independent curriculum requires various adjustments to the social system and institutional support. This research uses a qualitative approach with a case study type. The results of the study show that the role of teacher competence is very important in the implementation of the independent curriculum, especially in achieving the expected educational goals and ideals. In addition, teachers as professional educators have a good role to play in guiding, motivating, and teaching students according to the needs and demands of the industrial revolution 4.0.

ACC (Adaptive Cruise Control) is a crucial technology to control the automatic driving of a vehicle, which can automatically adjust the driving status of the vehicle according to the driving status of the vehicle in front so that the vehicle always keeps a safe distance from the vehicle in front, which can primarily relieve the driver's driving pressure and avoid tailgating. The research is of great significance to the realization of intelligent driving of vehicles. In this paper, the fuzzy PID control method is used to study the vehicle ACC system. Firstly, the basic concept and key components of the ACC system are explained, the vehicle longitudinal dynamics model is established, and the primary ranges of ,  and  parameters are determined through simulation; based on this, the fuzzy PID control algorithm of vehicle ACC is designed considering three different driving conditions of fixed speed and following cruise mode. The fuzzy PID control algorithm of the vehicle ACC system is designed and established. The joint simulation model of MATLAB is used to simulate the vehicle ACC system under three different driving conditions. The simulation results show that the vehicle ACC system designed in this paper ensures the safety and stability of following the vehicle while providing the vehicle's ride's comfort.
