Abstract

This study applies the Multi Attribute Utility Theory (MAUT) Method with the Rank Order Centroid (ROC) weighting approach in the promotion process at PT Gruti Lestari Pratama Mandailing Natal. This method provides an effective framework to overcome subjectivity in selecting the most suitable employees for promotion, based on criteria such as Length of Service, Performance, Loyalty, and Attendance. The steps of the implementation scenario include inputting criteria data, weighting using ROC, inputting sub-criteria data, alternative data, and assessment. The decision-making process is carried out through the MAUT Method, which integrates criteria preferences and assessments. The results of this study obtained that the best alternative with a final utility value of 1.002 was "Sahrul Nst", which was considered the most suitable for promotion. Thus, Sahrul Nst was selected to be promoted to Assistant Head (Askep) this year at PT Gruti Lestari Pratama. The results of this study prove the effectiveness of the MAUT and ROC methods in providing a more objective and structured basis for decision-making on promotion at PT Gruti Lestari Pratama Mandailing Natal.

Abstract

Investment is a crucial activity in long-term financial planning that requires careful consideration of various alternatives and criteria. Choosing the right investment is often challenging due to the diverse characteristics of each asset, such as return potential, risk, liquidity, and maintenance costs. To support the decision-making process, this study developed an investment recommendation system using the Weighted Product (WP) method with criterion weighting based on the Rank Order Centroid (ROC) approach. The WP method is applied to calculate the preference scores of each investment alternative, while ROC is used to determine objective criterion weights based on their ranked importance. The study evaluated ten investment alternatives using six evaluation criteria. The results indicate that Gold Bullion is the most recommended investment, achieving the highest WP score (1.0364), followed by Property (0.9620) and Luxury Jewelry and Watches (0.8558). The proposed system proves to be effective in producing rational and consistent recommendations that support data-driven decision-making. This research contributes to the development of adaptive and objective investment decision support systems.

Abstract

The wider the use of the internet network, the more vulnerable a sender of information is to wiretapping that can change the authentication and integrity of the data. Often someone who wants to send a message to someone else, does not want the message to be known by others. Usually the contents of the message are very confidential, which can only be known between the sender and the recipient of the message or a limited circle. To solve the problems described above, an application will be built to insert messages into audio using the Microsoft Visual Studio 2010 programming language that is able to insert messages into audio by implementing the Three Sided Side Match Method. This research is also expected to be able to maintain the confidentiality of messages inserted into an audio file so that there is no data leakage to unwanted parties because it is confidential and avoids wiretapping of information contained in the audio when exchanging information online.

Abstract

Tutoring plays a crucial role in supporting students' academic achievements by providing additional services outside of school hours. However, the manual management systems still applied by many tutoring centers, such as Bimbingan Belajar Ceria, have caused various issues, including inefficiency and susceptibility to human error. This study aims to develop a web-based Tutoring Management System using the Rapid Application Development (RAD) method. RAD was chosen because it can accelerate the development process through prototyping and iterations that allow adjustments based on user feedback. This is evidenced by the project being completed on time, within approximately 4 months. The system's development results show that the software produced is capable of managing student registration, payments, scheduling, and teacher data. Furthermore, the quality of the software meets expectations, as reflected by the evaluation conducted through usability testing. The test results showed a score of 88%, classified as "Good," indicating that the final product successfully meets user needs

Abstract

Stress is a psychological issue commonly experienced in society and can develop into more serious disorders if not properly addressed. However, access to professional services remains limited due to constraints such as time, cost, and unequal distribution of mental health professionals. Therefore, the objective of this study is to develop an expert system using a web-based Dempster-Shafer Theory (DST) approach capable of diagnosing stress types based on user-reported symptoms. DST enables the integration of various pieces of evidence to produce conclusions with measurable confidence levels. The system is equipped with functionality for managing symptom data, stress types, and the ability to provide diagnostic results accompanied by recommended solutions. Testing results demonstrated an accuracy level of 93.33%, placing this system in the "Good" category according to standard performance evaluation classifications. The implementation of DST has proven effective in managing data uncertainty and supporting confidence-based decision-making. This research contributes to the development of DST-based diagnostic technology that can be widely accessed via a web platform, providing a reliable alternative for early detection of stress types.

Abstract

Indonesia is one of the countries with abundant and stunning natural wealth, making it an ideal tourist destination. As a tourist destination, Indonesia has many hotels, including 5-star hotels, that offer comfort and luxury to tourists. However, with the many choices of 5-star hotels available, prospective visitors often face difficulties in finding a hotel that suits their preferences and needs. The main problem faced is the difficulty in obtaining accurate and reliable information about the facilities, prices, and room availability, as well as the quality of service of these hotels. To address this issue, this research presents a Decision Support System (DSS) that uses the Multi-Objective Optimization by Ratio Analysis (MOORA) method to assist prospective visitors in choosing the best 5-star hotel in Indonesia. This DSS considers various important factors such as location, facilities, price, and customer reviews to provide recommendations that best meet the visitors' needs. The results of the study show that from the 12 hotel data analyzed, the 5-star Hotel Bumi Surabaya City Resort (A10) ranks first with a score of 0.3862. The second rank is occupied by the 5-star Four Seasons Hotel Jakarta (A7) with a score of 0.3241, and the third rank is the 5-star The Ritz-Carlton Bali Hotel (A5) with a score of 0.2987. This DSS is expected to help prospective visitors make smarter and more optimal decisions, thus making their stay more enjoyable and satisfying. This research contributes to providing better and more accurate information for prospective visitors and helps in a more efficient and effective decision-making process. The advantage of this research is that the developed DSS can process data from various sources quickly and accurately, providing recommendations that match user preferences. The MOORA method used has also proven to be effective in filtering the best alternatives based on the specified criteria. However, this research also has several shortcomings, such as the limitation of the data used which only includes 12 hotels, so the results may not be fully representative. In addition, this DSS heavily relies on the quality and accuracy of input data, which can affect the final recommendation results

Abstract

In facing the development of the era and the era of technology that is developing rapidly at all times, the development of human resources is a top priority in national development, the position and position of students, have a very important role in the teaching and learning activities of students in order to improve student learning achievements in academic and non-academic fields, one of the things that motivates students to always develop themselves is to give an award as an outstanding student with the criteria that have been determined by the school. Temporary observations at Mustafa Private Vocational School in determining outstanding students are carried out manually. This method is considered still less effective and efficient. Based on this, a model for determining outstanding students is needed at Mustafa Private Vocational School with a more efficient and effective system. This system is designed using a decision support system through the Simple Additive Weighting (SAW) method. This system can display the ranking results of outstanding students based on the results of the SAW method calculations.

Abstract

Choosing the best hotel is often a challenge for travelers because many criteria must be considered such as price, facilities, location, and services. To overcome these problems, this study developed a decision support system (DSS) using Weighted Aggregate Product Sum Assessment (WASPAS) and Rank Order Central Weighting (ROC).The WASPAS method was chosen because it has the ability to combine the advantages of the weighted sum model (WSM) and the weighted product model (WPM), resulting in a more accurate and efficient decision.While the ROC method is used to determine the weight of each criterion objectively based on the importance of these criteria. From the calculation results, Hotel C ranks highest with a value of 0.877, indicating that this hotel meets the predetermined criteria better than other alternatives. In addition, other hotels such as Hotel A and Hotel D also performed quite well, occupying the second and third positions.

Abstract

In the digital era, the use of e-wallets is increasing along with the development of financial technology. However, the many choices of e-wallets available cause difficulties for users in making choices that suit their needs. This problem requires a solution in the form of a decision support system that can help users choose the best e-wallet. This research uses the Rank Order Centroid (ROC) method and Multi-Objective Optimization on the basis of Ratio Analysis (MOORA) to solve these problems. The ROC method is used to determine the weight of the criteria used, while the MOORA method is applied to evaluate e-wallet alternatives based on criteria that have been weighted. The selection of the ROC method is based on its ability to provide more accurate weighting based on the preferences of decision makers, while MOORA was chosen for its efficiency in processing and comparing complex alternatives. This research aims to develop a system that can provide recommendations for the best e-wallet based on criteria such as ease of use, security, transaction fees, and additional features. The contribution of this research lies in the application of the combined ROC and MOORA methods in the context of e-wallet selection, which has not been widely explored before. The results showed that based on the information obtained from table 5, the MOORA and ROC methods produced a value for the Dana application of 1.103 as alternative C1. With this highest value, Dana application is chosen as the best e-wallet. Thus, the proposed decision support system successfully provides the best e-wallet recommendations with a high level of accuracy and is able to accommodate various user preferences
