It has been researched about the change of exposure factors in radiographic examination of abdomen to radiographic quality and radiation exposure using computed radiography. The change of exposure factors to radiographic quality is obtained by measurement of radiographic density, which transmitted to step wedges and phantom abdomen. The density difference of step wedge and abdomen at each change of exposure factors result in radiographic contrast. To obtain radiation dose for patients, it is accounted by analytic method. The affect of scattering rate dose is obtained by measurement of scattering exposure rate using survey meter with positioned 100 cm from the object. The result of experiment shows that change of exposure factors in radiographic examination of abdomen makes no significant difference between radiographic density and contrast; however, it has decreased the patient dose. Keywords: radiation exposure, radiographic density and contrast

The development of the Internet of Things (IoT) has increased rapidly, and microcontrollers play a central role in the control and data communication in the IoT ecosystem. This research compares the data transmission performance between two popular microcontrollers, ESP32 and Raspberry Pi Pico, using the Wokwi simulation platform. The ESP32 is known for its Wi-Fi and Bluetooth connectivity, while the Raspberry Pi Pico with its RP2040 processor offers solid performance at an affordable price. In this context, MQTT is used as the communication protocol for data delivery with low latency and minimal bandwidth. This research includes three stages: system design, schematic design, and system testing. The scheme used includes DHT22 and LDR sensors, and the process of monitoring data to the Thingspeak server. The simulation results show that both microcontrollers can manage the data transmission well, but the Raspberry Pi Pico shows a faster transmission delay time than the ESP32. The average delay time for light intensity, temperature, and humidity parameters on the Raspberry Pi Pico was 2 minutes 36 seconds, 3 minutes 7 seconds, and 3 minutes 49 seconds, respectively, while the ESP32 had a longer delay time. This study provides insight into the performance of both microcontrollers in the context of the IoT and can help developers choose a suitable microcontroller for their applications

This study addresses public awareness of the legal provisions regarding the protection of personal data in the digital age, highlighting public understanding and attitudes towards applicable regulations in Kendari City, Southeast Sulawesi. The research employs a qualitative approach with empirical-normative methods, combining normative analysis of regulations and policies related to personal data protection with empirical testing of their implementation and social impact in society. The study reveals that although the public has a high awareness of the importance of maintaining personal data, only 40% of respondents are aware of Law No. 27 of 2022 on Personal Data Protection. The majority of the public lacks an understanding of legal concepts such as data controllers and data processing procedures. This shows a significant gap between legal awareness and understanding, which has the potential to undermine the effectiveness of implementing data protection policies. The findings indicate the need for more comprehensive education and stronger law enforcement to build public trust in digital data protection systems.
