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.

The problems come up when universities was mistake when initialize of what they needs. Utilization of applications of SI / IT that are not yet optimal include the lack of contribution, integration and innovation is suspected to be the cause factor. The most important thing to plan SI / IT is understanding the current condition to initialize the business needs through SWOT and Critical Success Factors analysis. The analysis will generate McFarlan portfolio matrix to determine the required applications by dividing it into 4 quadrants: support, key operational, strategic and high potential. The result of this application portfolio planning is a list of required applications now, in the future and mapping each of the proposed applications based on each function or part of the organization.

CAPTCHA are used to ensure that the operators are human not robots. The basic idea of using CAPTCHA is segmentation and recognition. Random characters, graphic images, or CAPTCHA audio become possible solutions to improve security and resilience for protection systems. In this paper used CAPTCHA random characters. However the CAPTCHA text needs to be analyzed again whether it is still solved by the computer or not it needs to be analyzed, improved, and developed to avoid automatic interference. Data set of text CAPTCHA paypal or so-called paypal HIP with 20 pieces of training data to get the template as much as 36 images that is from the numbers 0-9 and the letter A-Z. This particular paypal HIP data is limited by not using numbers 0 and 1 with the letters O and Q because of the similarity between the data. The method used starts from pre-processing, segmentation, and classification. Pre-processing techniques used consist of removing noise by tresholding and using cleaning techniques. We use bounding box and padding for segmentation method. And then for classification used counting pixel, vertical projections, horizontal projections, dan template correlation. By using these methods will be known which method can recognize CAPTCHA text accurately so as to affect the robustness of the CAPTCHA text.</em></p> Fitrah Maharani Humaira Tengku Musri Sarimuddin Sarimuddin Dwi Samsuifin Alham Aurista Miftahatul Ilmah ##submission.copyrightStatement## 2018-12-05 2018-12-05 2 2 29 33 Model Sistem Informasi Biaya Kunjungan Wisata di Provinsi Sulawesi Utara <p><em>Cost is one of the important information needed by tourists and prospective tourists in planning and conducting tourist visits.
