Abstract

The management of an organization often has many obstacles such as less optimal management of organizational documents, news portals, financial reports, correspondence documentation, activity documentation or data collection of members of the organization. Therefore, a reliable management system is needed so that management in the organization can be carried out more optimally. Likewise with the management in the Muhammadiyah Branch Executive, Batam Kota District, a reliable system is also needed to support the movement of various activities in the organization. The website-based information system developed is an answer to this problem. This system can be used to manage various activities and monitor their progress as well as make it easier for administrators to collect data on their members. This system can also display various institutional news so that the public is more familiar with the Muhammadiyah Branch Executive of Batam Kota District as a community organization with Islamic nuances that also carries out da'wah activities to spread goodness. So this is an agenda in this community service activity for the development of information systems and assistance in the implementation of the system both for managers and users of the system, as well as as a concrete step for the contribution of Higher Education in empowering the community by applying scientific principles that are useful for the benefit of the community.

Abstract

IEC TC10 is the most widely used Dissolved Gas Analysis (DGA) measurement dataset nowadays. Many DGA-based studies have been carried out using conventional methods and methods based on Artificial Intelligence Techniques (AITs). DGA is a diagnostic test performed on power transformers to detect and diagnose potential faults. The test involves analyzing the gases that are dissolved in the transformer oil, which can provide important information about the condition of the transformer. DGA is a widely used technique for transformer monitoring and maintenance in the power industry. However, this dataset is not perfect. There are still many problems in this dataset, one of which is the problem of missing value data. This problem will be significant if not appropriately handled. More reliable data from DGA measurement results is an in-dispensable reference in diagnosing faults in power transformers. This study focuses on dealing with the problem of missing value data using the Tertius algorithm, then testing the results using the J48 and Random Forest algorithms. The results obtained are pretty significant. Of the total 56 missing data, 36 could be predicted perfectly. And received the results of measuring accuracy using the J48 method of 62.73% and the Random Forest method of 70.71%. This result shows that the approach we applied is relatively good for handling missing values in IEC TC10 datasets.

Abstract

This study developed an image classification model to help learn the recognition of aircraft types using the Probabilistic Neural Network (PNN) method, one of the techniques in artificial neural networks that is often used for image classification. PNN works by classifying categories based on the calculation of the distance between the concentration and probability functions. In the process, PNN consists of four main stages: Input Layer, Pattern Layer, Summation Layer, and Output Layer. This study used 90 test data from three different object classes taken from the available data sets. The test results show that the application of the PNN algorithm in aircraft image classification provides an average accuracy of 81.11 %, which is quite promising to be applied as a learning module for the introduction of aircraft types for Aircraft Maintenance Engineering students at the Batam State Polytechnic. The results of this study show that the PNN method has great potential to help automatic classification and can be optimized to improve the accuracy of classification in further learning.

Abstract

The development of information technology has had a significant impact on the effectiveness and efficiency in organizational management, including within the Muhammadiyah Branch Executive (PCM) of Batam Kota District. However, in its operations, there are still obstacles in data management, information delivery, and reporting activities that are still carried out manually. Therefore, this research aims to develop a website-based organizational information system digitization application that can help in managing information and administration in a more structured and efficient manner. The system development method used is the Waterfall model approach which consists of several stages, namely needs analysis, design, implementation, testing, and maintenance. The analysis stage is carried out by collecting data through interviews and observations to understand the needs of the system. The designing stage involves the design of the system, database, and user interface. Implementation is carried out by building applications using the Laravel Framework which has an MVC (Model-View-Controller) architecture for more structured code management. Data storage is carried out using a MySQL database which allows for faster and organized information management. After that, the testing stage is applied to ensure that the system runs according to the specifications that have been determined. The results of the study show that the application developed can increase efficiency in the management of Batam City PCM administration such as recording member data, activity schedules, and automatic report making. Testing of the system using the Black Box Testing method shows that the application works well without any functional errors. With this application, it is hoped that PCM Batam Kota can be more optimal in managing the organization and conveying information to its members effectively.

Abstract

The determination of the composition of personnel in an organization, especially in the activities of the Branch Conference (Musran) of the Muhammadiyah Branch Executive of Belian Village, is still done manually and tends to be subjective. This has the potential to cause inefficiencies and internal conflicts in the decision-making process. This research aims to develop a web-based decision support system (SPK) that can help the management selection process objectively by using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. The TOPSIS method was chosen because it is able to provide the best alternative ratings based on its proximity to positive and negative ideal solutions. The five main criteria used in decision-making include: organizational experience, level of education, loyalty to the organization, leadership, and availability of time. The system is designed using the PHP programming language and MySQL database. The results of the implementation show that the system is able to produce recommendations for a more systematic, transparent, and accountable management structure. With this TOPSIS-based SPK, the deliberation process can run faster and more efficiently without eliminating the principle of democracy in the organization. This research is expected to be an innovative solution in adaptive and sustainable information technology-based organizational governance.

Abstract

The aim of this research is to test and compare the performance of the ELECTRE method with MOORA in decision making. By using the attribute weighting process, namely the calculation of Information Gain in both methods, the attribute weights are obtained systematically and objectively, therefore they are no longer determined by the assumptions of decision makers. The test data instrument used is a dataset from the UCI Machine Learning Repository, namely the Fertility Dataset which is data on the level of sperm fertility concentration with 100 data records, 9 attributes, 1 class variable and the data set is multivariate. The results of testing the ELECTRE and MOORA methods in this study indicate that the two methods have differences in the results of ranking the best alternative for sperm fertility concentration levels. The ELECTRE method produces A2 as the best alternative, while the MOORA method produces A16 as the best alternative. Then in terms of program execution time, the MOORA method is faster, namely 0.02 seconds, while the ELECTRE method execution time is 1.88 seconds.

Abstract

Home Ownership Credit (KPR) is the process of buying a house by way of credit or installments for a certain period of time and a determined interest rate. Problems that often arise in the process of granting mortgages are when providing an analysis of recommendations for the suitability of a house, such as credit analysis errors which often result in bad credit payments and disrupt the fund circulation system between credit payments and receivables. Billing. In addition, there is no filter in determining the eligibility of providing credit computerized, the system is equipped with a decision support system that can describe the supporting factors that are used as a calculation weight in making decisions on determining home ownership loans for those who deserve to receive them. To analyze the feasibility of providing home ownership loans, a decision support system is needed that can provide a good analysis to determine the creditworthiness of home ownership with the VIKOR method and the Entropy method. The Entropy method is applied to determine the weight of each criterion and the VIKOR method is used to rank alternatives. Based on the results of the study, the VIKOR method and the Entropy weighting method can provide recommendations for providing home ownership loans to eligible customers based on specified criteria. The ranking results were obtained by testing variations in the VIKOR index value with the best alternative result, namely A3 (3rd Alternative). And the Entropy method produces objective and proportional criteria weights and obtains valid criteria weights without having to give criteria weights manually or subjectively, so it is useful for determining the weight of criteria that need not be doubted about their validity.
