Abstract

The majority of Indonesia's population is Muslim, including more than 13,000 people with hearing impairments. In carrying out congregational prayers, the Deaf find it difficult to follow the instructions of the Imam's movement. The presence of hearing aids cannot be used by all persons with hearing impairments, and hearing aids often cause a buzzing sound, thus disturbing concentration. Therefore, in this study, a gyroscope bracelet will be made to assist people with hearing impairments in following the instructions of the Imam's movement when carrying out congregational prayers. The bracelet worn by the Imam will send a code in the form of a change in angle to the bracelet used by the Deaf congregation. The Z angle is a vertical angle in the gyroscope where the Z angle has an angular velocity of 360 degrees per second. The control system uses Arduino nano FT232RL FTDI FT232. The communication module uses HC-12 SI4463, with a wireless frequency of 433.4 - 473.0 MHz. The sensor for detecting changes in motion is the MPU6050 gyroscope sensor, the vibration indicator uses a micro vibrator motor. The bracelet used by the deaf will read the code from the Imam's device, with a notification in the form of a different vibration on every change in prayer movement. After experimenting with 30 people, the percentage of success was 84% ​​for all prayer positions. Thus, the gyroscope bracelet tool for prayer guides for the Deaf can help the Deaf community in carrying out congregational prayers.

Abstract

The research aimed to analyze the effect of leader-member exchange, work-life balance, and job satisfaction on Organizational Citizenship Behavior (OCB). The respondents were nursing staff at a hospital in Indonesia. The sample was 169 respondents, taken using a purposive sampling technique. Structural Equation Modeling (SEM) method was applied as the data analysis techniques with the application AMOS 22.0. Based on the results, the research finds that first, leader-member exchange and work-life balance have a positive and significant effect on job satisfaction and OCB. Second, job satisfaction affects OCB positively and significantly. Third, job satisfaction mediates the influence of leader-member exchange on OCB significantly. Fourth, job satisfaction also mediates the effect of work-life balance on OCB significantly. In conclusion, fostering OCB in hospitals is very important to produce better health service performance. The research shows that by increasing leader-member exchange, worklife balance, and job satisfaction, it can improve OCB. Overall, the research presents a significant contribution to the development of research in the field of human resource management and organizational behavior in the health sector in Indonesia.
