Abstract

Public Relations practise is deliberate, planned and sustain effort to establish and maintain mutual understanding between an organizational and its public. Public relations as good image maker for Indonesia communication and information ministry has strategy for internal and eksternal public. Four step program public relations with researching, planning, implementing and evaluating to make positive image of the Indonesia communication and information ministry. Employee relations aktivities such as traning, workshop, in house bulletin are the implementation of the internal strategy. Media relations activities for eksternal public : press release, press tour, coffe morning building the positif image of Kemenkominfo.

Abstract

Ground Penetrating Radar (GPR) has become an essential tool in mapping and imaging subsurface features. However, to enhance precision and control in GPR usage, a GPR drive system utilizes stepper motor technology. The study focuses on the importance of precise control over GPR movement to improve scanning accuracy and image quality. By integrating stepper motors into the drive system, the research endeavors to enhance the precision, reliability, and efficiency of GPR in subsurface scanning. Through detailed design steps, the implementation of stepper motors aims to structurally and measurably control GPR movement. The design and construction of the GPR drive system using stepper motors aim to enhance precision and control in subsurface scanning. Through detailed design steps, the implementation of stepper motors aims to structurally and measurably control GPR movement. The design and construction of the GPR drive system using stepper motors aim to enhance precision and control in subsurface scanning. The integration of GUI and Arduino IDE in stepper motor control has proven effective, providing consistent and accurate control. Performance analysis indicates that stepper motors with A3967 drivers exhibit high accuracy, particularly in movements ranging from 0.5 to 2 cm, with insignificant errors. Stepper motors also demonstrate consistency across various speeds, while the direct relationship between pulse duration and duty cycle influences speed and position control with precision. Thus, the utilization of stepper motors in the GPR drive system improves precision, control, and image quality in subsurface scanning , supporting GPR applications in fields such as geology, archeology, and construction. Keywords : GPR, XY Coordinates, Stepper Motor, Automated drive system, Arduino IDE, and Scanning Precision
