One of the services in the hospital is inpatient services and the role of nurses who have an important role in serving patients. Some problems in hospitalization services that occur such as manual nurse calls are done by visiting the treatment room and proposing the desired service. This method is less effective because it will require a long process in service. The application of nurse calls is done to improve services so that nurses can provide the best service and patient health can be monitored properly. The calling system for nurses is based on client-server and additional features such as heart detection, temperature detection, and emergency buttons that have the role to call nurses. The advantage of the nurse call application is that it can monitor patient health from several detection devices that will automatically call through the application. In addition to handling patients will be monitored by the hospital, the nurse's performance will also be detected. The results of this study are that the nurse call process will be automatically carried out by a detection device so that the nurse will detect the patient's condition quickly, the patient handling data will be stored on the server, therefore the history of heart rate and temperature records is more complete and can be used for doctors to handle patients.</p> Cahya Vikasari Purwiyanto Purwiyanto Galih Mustiko Aji ##submission.copyrightStatement## 2018-12-03 2018-12-03 2 2 01 08 Rekomendasi Perbaikan Infrastruktur TI SMK Berdasarkan Evaluasi Tingkat Kematangan Framework COBIT 5 <p><em>Starting from 2017, the management policy and education authority of Vocational High School in district region is taken over by the provincial government.

This technique strongly supports broadband communication that is currently being developed. An optical amplifier (EDFA) is required for transmitted information to be received at the appropriate distance limits. The problem, where EDFA should be located and how to overcome the chromatic dispersion of signals occurs, especially on remote communications using SMF 28. The power budget analysis starts from the calculation of the distance between the amplifier and the strengthening of EDFA using the solution wave equation, where the large dispersion of chromatic fiber and the desired range becomes the determinant of the optical amplifier. Case study for 200 km of communication distance need three amplifiers with a space of about 80km. When a 1 GHz bandwidth is converted to 10 GHz, OSNR on each amplifier will decrease by 10 dB.</em></p> Sri Danaryani ##submission.copyrightStatement## 2019-01-04 2019-01-04 2 2 67 71
