As a hospital that already uses an information system, information security must be maintained. One approach that can minimize attacks on information security is to implement information security governance. The aim of the research is to governance information technology security using COBIT 5. The method of analysis in this study uses the COBIT 5 framework using the DSS05 sub domain and uses the COBIT capability level (level 0-5) method of evaluation results. This study produces recommendations for improvements in information technology security in accordance with the level of capability achieved. The conclusion drawn from this study is the improvement in the level of capability and information security governance recommendations.</em></p> Ari Andrianti, Lola Yorita Astri Copyright (c) 2020 Ari Andrianti, Lola Yorita Astri http://creativecommons.org/licenses/by-sa/4.0 http://ijcs.stmikindonesia.ac.id/index.php/ijcs/article/view/297 Thu, 29 Oct 2020 00:00:00 +0000 Implementasi Solar-Cell Untuk Fasilitas Gratis Wisatawan dan Media Promosi Pariwisata Kota Padang http://ijcs.stmikindonesia.ac.id/index.php/ijcs/article/view/248 <p><em>Solar-Cell panels function is to capture the energy of sunlight and then convert it into electrical energy. In this tool, Solar-Cell panels can move according to the tilt of the sun's direction of motion so that the captured sunlight can be maximized. The electrical energy is used for free tourist facilities such as lighting, internet wi-fi, charging electronic devices, CCTV, and LCD. This tool will be placed in one of the tourist attractions in the city of Padang. So far, based on observations, tourists do not like to linger in tourist attractions because of the lack of free facilities for tourists. They cannot charge their gadgets, cannot access free internet, feel unsafe because there are no CCTV cameras and no audio-visual media. The purpose of this tool is made to increase the number of tourist visits to tourist attractions in Padang so that it can increase the PAD of Padang</em><em>.</em></p> Halifia Hendri, Hasri Awal, Mardison Mardison Copyright (c) 2020 Halifia Hendri, Hasri Awal, Mardison Mardison http://creativecommons.org/licenses/by-sa/4.0 http://ijcs.stmikindonesia.ac.id/index.php/ijcs/article/view/248 Thu, 29 Oct 2020 00:00:00 +0000 Prototype Animasi Lights, Fountains dan MP3 Sebagai Penarik Wisatawan di Kota Padang http://ijcs.stmikindonesia.ac.id/index.php/ijcs/article/view/289 <p><em>Taman Imam Bonjol, as one of the cultural tourism in Padang City, has not been utilized optimally by local or foreign tourists for relaxation. This study aims to attract tourists in the city of Padang for daily relaxation in the Imam Bonjol park, especially at night. Besides that, it can also be used as a promotional medium to increase regional income in the city of Padang. In this research, the method used is experimental method because this research produces a product in the form of a prototype. The product prototype designed in this study is controlled by a smartphone in determining the animation of lights, fountains and MP3s. This system also uses a Push Button for timing animation and timing and a matrix panel as a container for displaying text from existing activities. This system can run simultaneously at one time if needed. Water fountain can produce perfect animation with servo degree&gt; = 85 and &lt;= 95</em>.</p> Retno Devita, Ruri Hartika Zain, Ipriadi Ipriadi Copyright (c) 2020 Retno Devita, Ruri Hartika Zain, Ipriadi Ipriadi http://creativecommons.org/licenses/by-sa/4.0 http://ijcs.stmikindonesia.ac.id/index.php/ijcs/article/view/289 Thu, 29 Oct 2020 00:00:00 +0000 Analisa Kelayakan Tempat Pemakaman Umum Bagi Masyarakat Etnis Tionghoa Berbasis Web GIS http://ijcs.stmikindonesia.ac.id/index.php/ijcs/article/view/288 <p><em>Public cemeteries have a management structure that has been regulated by the local government. If the structure does not run according to its functions and duties, it will cause a problem. Likewise for the Chinese Ethnic residents, where in choosing the location and layout of the tomb according to feng shui they still use the subjective aspect. Therefore, a web-based Geographic Information System (GIS) was built, including tomb layout where the system provides information about the tomb grouping, tomb owner information, tomb rental price information, tomb conditions, number of tombs that are still empty and makes a feasibility analysis of the level funeral suitability. The feasibility analysis of the Public Cemeteries of Chinese Ethnicians uses the Multifactor Evaluation Process (MFEP) method. Making it easier for ethnic Chinese people to determine the layout of the tomb in accordance with their feng shui and assist the Department of the environment in providing information about the layout of the tomb and grouping the tombs to be better ordered </em></p> Andrew Kurniawan Vadreas, Dwi Welly Sukma Nirad, Nofri Aldo Copyright (c) 2020 Andrew Kurniawan Vadreas, Dwi Welly Sukma Nirad, Nofri Aldo http://creativecommons.org/licenses/by-sa/4.0 http://ijcs.stmikindonesia.ac.id/index.php/ijcs/article/view/288 Thu, 29 Oct 2020 00:00:00 +0000 Klasifikasi Jenis Pisang Menggunakan Support Vector Machine dengan Fitur GLCM dan HOG http://ijcs.stmikindonesia.ac.id/index.php/ijcs/article/view/303 <p><em>Banana fruit supplies not only the domestic market, but also the international market. In the process of introducing a variety of bananas are generally done in two ways, firstly done manually by humans to introduce bananas and secondly to use destructive methods by taking samples. The problem that occurs in this second process is having relatively large and greater costs. This requires a system that can classify bananas using digital image processing and the Vector Support Machine (SVM) implemented in this study. The image of a banana is taken with a Xiaomi Note 4x cellphone camera and is processed using Matlab software. Digital images are used to extract the shape and texture features of bananas, while SVM is used for banana classification. This study uses 420 images of bananas divided into 7 classes, namely Ambon banana class, Barangan banana class, golden banana class, Kepok banana class, Raja banana class, milk banana class and banana horn class. Where in the test using cross validation for 7 classes of bananas. SVL is able to classify the types of bananas in the image with GLCM and HOG features in iteration 1 with an overall accuracy of 74.28% in the type of milk bananas</em></p> Herry Kamaruddin Sanjaya, Novan Wijaya Copyright (c) 2020 Herry Kamaruddin Sanjaya, Novan Wijaya http://creativecommons.org/licenses/by-sa/4.0 http://ijcs.stmikindonesia.ac.id/index.php/ijcs/article/view/303 Thu, 29 Oct 2020 00:00:00 +0000 Pengembangan Media Pembelajaran Berbasis Android pada Mata Pelajaran Simulasi Digital http://ijcs.stmikindonesia.ac.id/index.php/ijcs/article/view/304 <p><em>Based on the observations, it was found that vocational schools in Padan</em><em>g </em><em>have </em><em>an </em><em>adequate facilities for technology-based learning activities.
