<![CDATA[Electronic money or e-money is a technological innovation that allows payment transaction processing to be easier and more practical. PT Aino Indonesia is a payment gateway company that serves payment processes using this technology for various business segments. To satisfy the requirements of each business segment, Aino needs to develop a wide range of applications. These applications require a standard for the payment system to make it faster to integrate and maintain. The payment team at Aino has developed a module or SDK that provides a standard payment system for Android-based applications. Two new features will be added to this SDK, the logging feature and log file upload. The logging feature will record the data generated by each transaction process into a log file. Next, the SDK will upload the log files to the server to help retrieve transaction data uploaded from the device. Both features will help the process of tracking issues and problems that may arise during the transaction process. The development of the two features in this SDK uses the Scrum method to ensure it stays on track.]]>

<![CDATA[The Gerenete and test algorithm is a very simple method in a heuristic search. The principle of this method is a combination of the depthbforst search method with backtracking because it produces a complete solution before the test process is carried out. If the work process is carried out systematically and follows the procedure, it will find a solution. The problem in this research is that if the problem is broad and large, it will likely take time to find a solution. The main purpose of this research is to test the distance in order to find a solution so as to produce a solution that is fast and saves time. Generate and test work system, namely 1. Generate a possible solution 2. Test each node which is a solution by comparing the node with the end node of a selected path with a set of expected goals. 3. If a solution has been found, then exit the system. If you haven't found a solution, then return to step 1. The final result of the research is the point F(A-B-E-I-L-T) with a heuristic number of 14]]>

<![CDATA[STMIK Syaikh Zainuddin NW Anjani always strives to improve quality or internal quality sustainably as a strategy to be able to compete with other universities. The institution itself realizes that to achieve educational goals and maintain the quality of education and produce good outputs, it requires commitment, strategies, appropriate methods, and adequate human resources in the process of achieving it. One way to improve the quality of a university is to select teaching staff or lecturers because the quality of lecturers will greatly determine the high and low quality of a university. Based on the problems that arise, a decision support system is needed that can handle the influence relationship between parameters for the selection process for lecturer acceptance. In this study, the Analytical Hierarchy Process (AHP) method and the Multi-Objective Optimization on the Basis of Ratio Analysis (MOORA) method were used to determine alternative priorities for prospective lecturers. The AHP method is used to determine the weight of the criteria, sub-criteria, and scoring data, while the MOORA method is used to calculate the final score and ranking.]]>

<![CDATA[Unemployment in Indonesia is currently increasing. This can be seen from the number of unemployed and workers who are looking for job vacancies either directly or through applications. The problem in this study is the lack of understanding of job applicants about the terms or criteria for applying for a job so that they are not accepted in a company. There are five criteria that must be considered in applying for a job, namely, education, vacancies, age, opportunities and knowledge. The purpose of this study is to help job seekers to complete and understand the criteria that have been set. This study uses the Sugeno method with the final result in the form of linear or constant. The working process of the Sugeno method is fuzification, inference engine, application of implication and defuzzification functions to obtain results in accordance with the decision-making system.]]>

<![CDATA[The rapid development of email use and the convenience provided make email as the most frequently used means of communication. Along with its development, many parties are abusing the use of email as a means of advertising promotion, phishing and sending other unimportant emails. This information is called spam email. One of the efforts in overcoming the problem of spam emails is by filtering techniques based on the content of the email. In the first study related to the classification of spam emails, the Naïve Bayes method is the most commonly used method. Therefore, in this study researchers will add Random Forest and K-Nearest Neighbor (KNN) methods to make comparisons in order to find which methods have better accuracy in classifying spam emails. Based on the results of the trial, the application of Naïve bayes classification algorithm in the classification of spam emails resulted in accuracy of 83.5%, Random Forest 83.5% and KNN 82.75%]]>

<![CDATA[Conventional cryptographic algorithms cannot be applied to solve a plaintext (message) into several ciphertexts because conventional cryptographic algorithms can only produce a ciphertext from a plaintext (message). In this case, a cryptographic protocol can be applied, namely the Asmuth-Bloom secret sharing protocol. The methodology used to analyze and design application software and learning the Asmuth-Bloom secret sharing protocol is the Waterfall method. This research is intended to produce a learning software that is able to display the working process of the Asmuth-Bloom secret sharing protocol and the application of the Asmuth-Bloom secret sharing protocol. The working procedure described by the software includes the key formation process, the shadow formation process and the shadow merge process. The software also provides an interface to do the process of splitting a text file into n shadow files and merging m shadow files into the original text file. In addition, the software also provides basic theories related to the two cryptographic protocols and reports the results of the calculation process are stored in a text file with *.txt extension]]>
