Sometimes Raskin distributes obstacles, constraints can be from the community or the officers themselves. The problem faced is that the assessment is still subjective. This is feared to cause inaccuracies in the assessment so that Raskin is not on target.</em></p> <p><em>Raskin distribution must be carried out well, transapreated and organized so that the Raskin received is right on target and truly the people in need. Therefore a decision support system is needed to assist officers in selecting citizens who are entitled to receive Raskin assistance based on predetermined criteria. The decision support system method used in this decision is the Analytical Hierarchy Process (AHP) method for processing the data. In designing this system used tools such as DFD and Flowchart while the system development method uses the waterfall method.</em></p> <p><em>The Raskin Recipient Selection Decision Support System in Tanjung Harapan Kotabumi Village using the Analytical Hirarchy Process (AHP) method makes it easy to process data and make decisions to determine families who are unable and eligible to receive Raskin assistance and make it easier to make Raskin recipient reports.</em></p> Merri Parida, Merina Merina ##submission.copyrightStatement## https://dcckotabumi.ac.id/ojs/index.php/jik/article/view/134 Mon, 28 Oct 2019 01:09:05 +0000 ANALISA INFRASTRUKTUR TEKNOLOGI INFORMASI MENGGUNAKAN FRAMEWORK COBIT 4.1 https://dcckotabumi.ac.id/ojs/index.php/jik/article/view/145 <p><em>STMIK Dian Cipta Cendikia Kotabumi is one of the tertiary institutions operating in information technology, such as academic information systems, journal information systems and others, but at STMIK Dian Cipta Cendikia Kotabumi does not yet have an indicator that can state that the performance of information technology is in accordance with goals to be achieved.

The selection process for the megou Pak Tulang Bawang University is still done manually. is reguired decision support system in order to increase the effectiveness of decision making and reduce subjectivity in the decision making process. One of them is the AHP (Analytical Hierarchy Process) method. The criteria used for the selection process of permanent lecturers and non-permanent lecturers are GPA, TPA (Academic Potential Test), TOEFL (Test of English as a Foreign Language), Microteaching, and Interview. The AHP (Analytical Hierarchy Process) method is often used because this decision support method will elaborate multi-factor or complex multi-criteria problems into a hierarchy. By using AHP method, lecturer recruitment becomes more effective, selective, and integrated in the effort to find qualified and permanent lecturers at Megou Pak Tulang Bawang University.</p> Darsin Darsin, Muhardi Muhardi ##submission.copyrightStatement## https://dcckotabumi.ac.id/ojs/index.php/jik/article/view/149 Mon, 28 Oct 2019 01:20:10 +0000 DATA MINING UNTUK MENENTUKAN PRODUK TERLARIS MENGGUNAKAN METODE NAIVE BAYES https://dcckotabumi.ac.id/ojs/index.php/jik/article/view/150 <p>PT.

One form of democracy in Indonesia is to hold an election (General Election) once every five years. Elections are not only carried out at the central government but also to the regional government and even the government where we live. The existence of community institutions aims to accelerate an orderly, safe and prosperous community. This research was conducted to classify the criteria for the selection of candidates for RW (Rukun Warga) candidates in an area in the city of Batam, the problem that has occurred so far is the process of selecting or determining prospective RW heads. which must be used as a basis for determining candidates, as well as voters do not know clearly who is elected or may vote on the basis of just knowing the candidate, so that the actual purpose of voting for the RW chairman is not achieved. In the selection of citizen participation is very necessary but not all residents participate in this event, of course this raises problems after the vote, many of the residents who do not know who the RW is chosen to do not know the background of the leader in their housing, besides the candidates RW chairman did not conduct a comprehensive socialization of the future vision and mission in community development, this situation led to complaints from the community such as when making an election they did not vote based on good criteria to be the deputy leader where they lived. Based on the above problems, the researcher will use a data lamination technique with C4.5 algorithm which aims to classify the criteria of prospective RW heads so that they can make decisions about the determination of RW candidates. Based on the results of the C4.5 calculation by applying the decision tree criteria expected by the community to become the candidate for RW leader who will be chosen with the highest gain value is to have a vision and mission as a candidate, have a level of solidarity with the proud and have a good leadership spirit.</em></p> Erlin Elisa, Rika Harman ##submission.copyrightStatement## https://dcckotabumi.ac.id/ojs/index.php/jik/article/view/153 Thu, 24 Oct 2019 00:00:00 +0000 IMPLEMENTASI KRIPTOGRAFI BERBASIS CAESAR CHIPER UNTUK KEAMANAN DATA https://dcckotabumi.ac.id/ojs/index.php/jik/article/view/163 <p><em>Cryptography is a part of science that studies about how to keep data or messages safe.
