Abstract

Assessing community resilience is challenging due to the complexity of influencing factors. Various frameworks and models, such as the PEOPLES framework, have been developed for both theoretical and practical applications. In dealing with uncertainty, selecting the right model is crucial. While probabilistic approaches are common, they can be insufficient. Fuzzy logic, as an uncertainty model, offers a solution. This study explores community resilience in Bekasi City using fuzzification and trapezoidal membership functions for input variables categorized as low, medium, and high. The output uses triangular membership functions with four degrees: low, medium, high, and very high, ranging from 43-129. Fuzzy rule formulation applies the "minimal" function with 2,187 basic rules. The test results show high accuracy, with predictions for six regional segments matching expert assessments.

Abstract

Quantum Key Distribution is a cornerstone of secure communication, utilizing quantum mechanics to achieve unparalleled security. This study evaluates the performance of the B92 protocol, a simplified scheme using non-orthogonal states, through simulation with Python3 and the Qiskit library. The research focuses on the variability of key lengths and the ability of the protocol to detect eavesdropping attempts. Results show an average key length of 14.3 bits per 100 transmitted qubits, with variability ranging from 3 to 29 bits. Detection accuracy improves significantly with sample size, achieving 95% accuracy with a sample size of 5 and 100% with a sample size of 10. These findings highlight the trade-off between key length and detection reliability, emphasizing the importance of optimization. While simulations confirm the protocol’s robustness, further studies under real-world conditions are essential. This work advances the understanding of quantum cryptographic systems and lays the foundation for secure quantum communication.

Abstract

Research that addresses soil nutrient prediction with NIR mostly uses PLS algorithms. The advent of machine learning (ML) has resulted in automated learning methods to find the optimal model. Preprocessing in the development of prediction models is an important part. Spectrum preprocessing aims to eliminate uninformative sources of variance. Research on the best preprocessing methods is often determined through trial-and-error. The preprocessing approach compares a number of preprocessing operations but this method is less efficient. This research proposes the application of ML to find the best combination of preprocessing operations quickly and simultaneously. Preprocessing test results using 11 operators resulted in 2,112 combinations. The use of preprocessing techniques can improve the performance of all algorithms (RF, SVR, PLS, LR, and MLP). K soil element testing has the lowest error in LR, Mg, Ca, P, and pH soil element testing using MLP has the best performance and in N soil element testing the best performance in RF.

Abstract

This research developed a web-based human resource management system to address manual HR management issues in a financial institution. Manual HR management created challenges including difficult data integration, high risk of recording errors, and inefficient processes. The system was developed using the agile method with MySQL database, Laravel framework, and PHP programming language. This system integrated employee management, performance assessment, payroll, and recruitment modules. Testing was conducted using User Acceptance Testing (UAT) and stress testing method. Research results showed that the system successfully met user needs by optimizing digital and integrated employee data management. The system provided real-time information access, facilitated performance evaluations, and generated comprehensive HR reports. The implementation of this system improved operational efficiency, data accuracy, and decision-making quality through integrated HR management processes.

Abstract

Sulangai Village experiences limited internet access due to its geographical condition in a mountainous area, so cable infrastructure such as fiber optics is difficult to implement. The proposed solution is to use point-to-point wireless networks to provide reliable internet access. The research method used is the Network Development Life Cycle (NDLC), including the stages of analysis, design, simulation, implementation, monitoring and management. The test results show that the signal strength at the Base Station and Client Station is -69 dBm each, which is in the very good category. Security testing using IPsec VPN and GRE also showed adequate results, with the ability to encrypt data and protect the network from outsiders. Bandwidth speed testing before and after security implementation shows stable and satisfactory network performance, with consistent transmission and reception speeds. The results of the Quality of Service (QoS) analysis also show a significant increase after implementing security, with good throughput, packet loss, delay and jitter values.

Abstract

The Population and Civil Registration Office in an Indonesian district has introduced a web-based service system that enables easy access for the public anytime and anywhere. This website offers services such as birth certificate issuance, electronic ID cards (e-KTP), and various other civil registration documents. Despite advancements in service delivery, challenges persist, particularly regarding inadequate interface design that often confuses users. Through heuristic evaluation, it was found that 12 aspects require improvement with average scores below 2.50. Therefore, a redesign is necessary to address user interface issues. The redesign employs the Goal-Directed Design (GDD) method to provide better recommendations for website development. Following these improvements and subsequent heuristic evaluations, there was a significant increase in average improvement scores, reaching 4.13.

Abstract

This study aims to develop a sentiment analysis and POS (Part of Speech) system for student assessments of teachers in Indonesia. The system classifies assessment sentiment into positive and negative classes while identifying the topic of discussion. Testing results show that the w11wo/indonesian-roberta-base-sentiment-classifier model provides the best performance, achieving an accuracy of 0.87, with the highest precision, recall, and F1-Score for the positive class. The crypter70/IndoBERT-Sentiment-Analysis model ranks second with an accuracy of 0.84 but performs less optimally in detecting negative sentiment. Meanwhile, the mdhugol/indonesia-bert-sentiment classification model has the lowest performance with an accuracy of 0.80, particularly in predicting negative sentiment.

Abstract

The digital economy in Indonesia is growing rapidly, including in online lending services. Application X is one of the popular online lending applications, offering users convenience in applying for loans online. This research employs sentiment analysis on user reviews of Application X to understand their preferences and needs. The K-Nearest Neighbours (K-NN) method is applied as the primary algorithm for sentiment classification. Data collected through user review scraping undergoes a series of preprocessing stages, such as tokenization, stop word removal, and stemming, aimed at improving data quality. The K-NN model is tested in various scenarios to achieve the best results. The best scenario reveals that the highest accuracy is achieved by the K-NN model when the stop word removal process is not applied during the data preprocessing stage where the accuracy without using the stop word process was 92.9%, compared to 89.9% when using stop words.

Abstract

Information system security is a major focus for many organizations as increasingly sophisticated cyberattacks threaten the confidentiality, integrity and availability of online services. This research aims to identify and assess vulnerabilities in web applications at College X by using the OWASP framework and OCTAVE method. OWASP is used to identify common and critical web vulnerabilities, while OCTAVE provides a holistic understanding of an organization's security risks. Testing was conducted with the tools and techniques recommended by both frameworks. The results found a number of vulnerabilities, including two low-level and one high-level. The findings underscore the importance of systematic penetration testing and risk assessment to keep web applications secure in educational environments.
