Abstract

The development of information system today has led to various changes that significantly taken into account in an organization decision making to obtain precise and accurate information for use. In processing the data of alumni, STIE Prabumulih is still using computerized system. This way brings the lack of development of information includes vacancies information obtained by alumni and students which is neither accurate nor sufficient, hence it is necessary for STIE Prabumulih to have the development of information so that information obtained can be more accurated and updated. Programming language used is the Personal Hypertext Preprocessor (PHP) and design editor is Macromedia Dreamwaver CC 2015. The application also uses MySQL as its database so it can be helpful in inputting data in which it can be done   more quickly, precisely and efficiently. The study is  a descriptive design that aims to clarify the data obtained and give a detailed description of the existing alumni data collection system at STIE Prabumulih. Keywords: Alumni, website, PHP, MySQL, descriptive

Abstract

In this paper, we report the benchmarking results of Hyperledger, a Distributed Ledger, which is the derivation Blockchain Technology. Method to evaluate Hyperledger in a limited infrastructure is developed. The measured infrastructure consists of 8 nodes with a load of up to 20000 transactions/second.. The benchmarking of Hyperledger shows better than a database system in a high workload scenario. We found that the maximum size data volume in one transaction on the Hyperledger network is around ten (10) times of MySQL. Also, the time spent on processing a single transaction in the blockchain network is 80-200 times faster than MySQL. This initial analysis can provide an overview for practitioners in making decisions about the adoption of blockchain technology in their IT systems.

Abstract

Higher education institution must be able to well perform processes of evaluation, planning and management in order to win the competition in this globalization era. To support any effort of the aforementioned, the institution needs qualified and sufficient information supports so that it can probe and predict any potential strength which existed. Development data warehouse and data mining is kinds of solution alternatives which can be done to help organization in finding and understanding hidden patterns from the data provided. Data warehouse is a collection of integrated databases which is used to support the process of decision making. Data mining is a kind of analysis tool which is used to extract any information provided in the data warehouse. The research discussed a problem in designing data warehouse and applying data mining to support the academic system at IBI Darmajaya in representing potential information required for better academic services to learners. The first executed steps was establishing the data warehouse of IBI Darmajaya, then an analysis was conducted towards all saved data in the data warehouse by using data mining techniques. The results of this research is a data warehouse that can represent information to support the evaluation process and acceptance of new students campaign planning to the potential areas and school, advertising media that will be used, monitoring of students’ academic status, evaluation and planning of students’ study plans, and performance evaluation of study program within the aspects of alumni quality and length of study.  In addition, this research also result the application of data mining for finding the rules that used to driving and directing the students enthusiast and study program selection for prospective new students.

Abstract

Learning media that has been widely created and implemented in high schools and universities will certainly help students understand existing subjects, especially subjects related to theoretical arithmetic. Mathematical logic is certainly widely used in the development of computerization, computerization in the development of computer applications also has to do with arithmetic relations for the part of the process.Software engineering methods use prototypes to develop or develop system applications that have several steps, such as: Listen to Customer, Build / Revise mock-ups, Costumer Test. Completion of the stages of building automata learning applications is part of the development stage of the automata learning system application with the application of Finite State Automata (FSA).Application results with a GUI-based (User Interface Graph) design implemented to support the automata course material. Graphic automata application implementation to show the relationship between states resulting from the logic of the relationship results from each existing node. The resulting application has 2 important parts for the design stages, namely: process design (flowchart) and interface (Morkup). The results of all designs are further implemented with the Borlan Delphi visual programming language application. Testing with black box is done with a visual Graph verification scenario which is inputted with the suitability of the input and which is not to see the results of Tupel based on the graph that is successful and not successful. Keywords: automata, learning, application, Graph, Tupel.

Abstract

Decision support system is a system that can help the Department of Industry, Trade and Cooperatives in making decisions with the ability to determine the quality of cooperatives using AHP (Analytic Hierarchy Process), in which each criterion in this case the alternative assessment factors compared with one others so as to provide the output intensity value priorities that result in a system that provides an assessment of each cooperative in metro cities. This decision support system to the selection of each cooperative. With a selection value then it is useful to facilitate decision making on issues related to the tender auction, so we get the most viable cooperatives to serve as a quality cooperative. Keywords: Decision Support System (DSS), Ranking, AHP (Analytic Hierarchy Process).

Abstract

Postgraduate IIB Darmajaya in Management program in its curriculum offers concentration subjects in the third semester. Concentrations in the field of economics are grouped into three concentrations namely marketing, human resources (HR) and finance (Finance). In the third-semester students are required to choose one concentration of the field of economics according to their competence. But the obstacle is often found in the choice of concentration in the field of economics is that many students still unable recognize their interests and abilities. Besides, many students who choose the concentration in the field of economics only follow the most specialization, but do not follow based on their abilities. According to that, it requires the tool to able to provide decision support in term of selecting concentrations based on predetermined considerations. The methods used in solving this problem are Weighted Average Method and Tsukomoto Fuzzy FIS Method with 4 (four) input variables and 3 (three) output variables. Input variables consist of subject values, interest values, motivation values , and abilities. While the output variable consists of marketing concentration, human resources (HR) and finance (Finance) The sample was taken from second semester students of Master of Management.The test results show that the recommendation for the selection of the right concentration for these students is Financial specialization with a Defuzzification value of 65.91 higher than Marketing and Human Resources specialization which is 64,69 and 64,59, respectively Keywords: Decision Support System, Weighted Average Method, Tsukomoto Fuzzy FIS Method, Concentration
