Abstract

Decision Support Systems (DSS) have become an important tool in various fields to assist complex and critical decision making. In Padang Tualang District, North Sumatra, evaluating the performance of hamlet heads is a big challenge because it is done manually and unsystematically, which often results in inaccuracies and unfairness in the assessment. This research aims to develop and implement a web-based SPK that integrates the COCOSO and AHP methods to evaluate the performance of hamlet heads more objectively and transparently. The research stages begin with problem identification, followed by data collection through observation and interviews, as well as data analysis using the COCOSO and AHP methods. The system is then designed and implemented, followed by testing using black-box methods to ensure its reliability and functionality. The results of this system show that Jusmianto is ranked first in the performance evaluation with the highest score with a score of 281,495. System testing shows that all features function as expected, both for admin and user users. It is hoped that the implementation of this SPK can improve the quality of leadership at the hamlet level and encourage equitable development in all sub-district areas.

Abstract

Depression is a mental health disorder that is often unrecognized and can develop into a more serious issue if not addressed properly. One of the main challenges in managing depression is the lack of tools that can objectively measure the severity of symptoms and determine who requires immediate treatment. This study aims to develop an expert system based on Fuzzy Multiple Attribute Decision Making (MADM) with the Simple Additive Weighting (SAW) method to prioritize the treatment of depression symptoms based on criteria such as intensity, duration, and impact on daily life. The system goes through several stages, including data pre-processing, fuzzification, criterion weighting, decision matrix normalization, and ranking calculation using SAW, resulting in an accurate treatment priority ranking. The research findings show that this system can assist healthcare professionals in identifying individuals with the most severe symptoms who require immediate intervention, thereby speeding up treatment and improving the effectiveness of therapy provided.

Abstract

Security and efficiency of parking management are crucial aspects in the operations of companies and educational institutions. At Pelita Bangsa University, the conventional parking system still uses manual methods and paper-based tickets, which is inefficient and potentially creates security issues. In addition, the lack of integration between the parking system and vehicle identification increases the risk of theft. This research aims to design an RFID-based parking system that can be accessed using a Student Identity Card. The system uses RFID at low frequencies to ensure the security and accuracy of vehicle identification. The results show that the RFID system is able to efficiently replace conventional methods, reduce paper usage, and increase parking access speed. The system is also integrated with the student database, enabling better access control and automatic recording of vehicles. The implementation of the system in Pelita Bangsa University's parking area not only improves security but also user experience, with a faster payment process and structured vehicle data management. Hopefully, this system can be an innovative solution that can be applied in various institutions to face the challenges of parking security and efficiency in the digital age.

Abstract

A condition known as heart failure, where the heart is unable to pump enough blood to meet the body's needs for oxygen and nutrients, should not be taken lightly. This can result in a number of symptoms, such as fatigue, fluid retention, and dyspnea. The World Heart Federation estimates that up to 1.8 million people in Southeast Asia suffered from heart failure in 2014. For prompt and efficient treatment, heart failure is a medical problem that needs to be identified. This disease has the potential to worsen if not treated immediately. Several machine learning methods can be used to help diagnose and categorize this disease. One of them is the popular algorithm, namely Naive Bayes and K-Nearest Neighbors. Naive Bayes is a simple but very efficient probability-based machine learning algorithm, especially in classification applications. K-Nearest Neighbors is comparing the data to be predicted with a number of its closest data in a feature space based on a certain distance, such as Euclidean distance, Manhattan, or others. This study was conducted using Confusion Matrix to evaluate and compare the Naive Bayes and K-Nearest Neighbor algorithms in the categorization of heart failure disease by collecting data totaling 918 heart failure patient data from kaggle. Based on the research findings, the K-Nearest Neighbor method achieved an accuracy score of 76%, while the Naive Bayes approach achieved 90% accuracy using a ratio of 80:20.

Abstract

The current agricultural industry is still minimal in utilising technology so that limited access to information related to market demand and means of direct sales to consumers is a major obstacle in improving the welfare of farmers. The distribution process of agricultural products is still carried out conventionally through direct interaction, making it less effective and efficient. The development of information and communication technology, especially in the use of mobile devices, provides new opportunities to overcome existing problems. This research aims to solve the existing problems by creating a mobile-based application to increase sales of agricultural products. The application is developed using the waterfall approach method with several stages such as needs analysis, design, implementation, testing to maintenance. Flutter programming language is also used in coding the application system. Based on the design and implementation carried out in this study, an application is produced with features that display products and effective payment features. The existing features are then tested by 30 respondents with the black box testing method and the results obtained are 100% the application can run well. The application can increase transparency and efficiency in the sale of agricultural products. The application also provides convenience for farmers as consumers.

Abstract

This study investigates the performance of a sentiment classification model leveraging IndoBERT to analyze Indonesian hotel review data. Sentiment analysis is crucial for extracting actionable insights from customer reviews, yet challenges such as linguistic diversity and imbalanced datasets complicate accurate classification. The dataset comprises 90% Positive, 5% Neutral, and 5% Negative sentiments, reflecting significant class imbalance. A fine-tuned IndoBERT model was trained over three epochs, with performance assessed using metrics such as accuracy, precision, recall, F1-score, confusion matrices, and ROC and Precision-Recall curves. The results indicate high global accuracy (92.52%) and robust performance for the Positive class (F1-score: 96.09%, AUC: 0.90). However, significant limitations were observed for minority classes, with the Neutral class achieving precision, recall, and F1-scores of 0.00, and the Negative class obtaining a low F1-score of 28.57%. These findings underscore the influence of dataset imbalance, where the dominance of the Positive class skews model predictions. Future research should explore techniques such as oversampling SMOTE, reweighting loss functions, or hybrid architectures to mitigate imbalance and improve performance across all sentiment categories. This research contributes to advancing sentiment classification methodologies for Indonesian text, offering practical implications for enhancing customer feedback analysis in the hospitality industry.

Abstract

This study aims to analyze the application of C5.0 and K-Nearest Neighbor (K-NN) algorithms in the classification process for determining the optimal location for housing. The classification process involves several factors such as land price, accessibility, public facilities, crime rate, infrastructure, land availability, and consumer preferences. The research conducted tests on both algorithms to compare their performance in generating accurate predictions. The results show that the C5.0 algorithm outperforms K-NN, achieving an accuracy rate of 100%, compared to K-NN, which achieved an accuracy of 66.67%. This demonstrates that C5.0 is more effective in modeling data and producing more precise classifications. Therefore, it can be concluded that the use of data mining algorithms, particularly C5.0, greatly assists in the classification process for determining housing locations, providing more optimal results compared to K-NN.
