Abstract

Project progress is an important indicator of the success of construction, which includes four main criteria, namely time, scope, cost, and quality. These four aspects must be monitored continuously to ensure they remain in line with the plan that was established at the outset. However, at PT. Fitra Wika Pekanbaru, the project monitoring process is still carried out manually using Microsoft Excel. This method is considered inefficient because it is prone to delays in data updates, inconsistencies in information, and difficulties in recapitulating and analyzing projects comprehensively. To overcome these problems, this study applies the Web Development Life Cycle (WDLC) method in designing and building a web-based project monitoring information system. The system was developed using the PHP programming language with a MySQL database, supported by the Bootstrap framework to produce a responsive and user-friendly interface. The result of this development is an online-based project monitoring system that not only simplifies the data input and reporting process but also enables real-time and continuous monitoring of project progress. Furthermore, this system supports management in conducting evaluations and making faster and more accurate decisions by providing comparative information between project planning and realization. Thus, the implementation of this information system is expected to improve work efficiency, reduce the risk of data loss, and support transparency and accountability in construction project management at PT. Fitra Wika Pekanbaru

Abstract

This study was conducted to analyze the extent to which the use of a Virtual Private Network (VPN) can improve network security at SMK IT Insan Kreatif Tj.Morawa. The research method used was an experimental quantitative method with descriptive analysis. Data collection was carried out through direct experiments using the Wireshark application to capture network data packets in two scenarios, namely before and after the implementation of VPN. The sniffing data was analyzed to determine the type of protocol used and whether the data was encrypted or still clearly readable. The results showed that before using a VPN, important data such as login credentials on HTTP and FTP protocols could be read in plaintext, while DNS queries were also openly accessible. After using a VPN, all data was encrypted using the TLS/SSL protocol so that sensitive information was no longer visible in the Wireshark capture results. A comparison of the results of three tests showed that VPNs consistently provided better protection against data leaks

Abstract

Account security and identity validity are crucial aspects of online auction platforms to prevent price manipulation by fake bidders. Conventional authentication methods are often vulnerable to cyber-attacks or compromise user convenience for the sake of security. This study aims to implement a Two-Factor Authentication (2FA) system on the Mokasindo auction platform using WhatsApp Gateway integrated via REST API technology. The development method includes Webhook mechanisms for real-time user phone number validation and AJAX Short Polling techniques to deliver auto-login features without page refreshing. Black Box testing results indicate that the system successfully verifies user identity accurately and mitigates the risk of fictitious account registration. This implementation offers an optimal balance between system security and User Experience (UX), with an average recorded verification process latency of only 3.5 seconds. This solution proves effective in creating a more secure, responsive, and trustworthy auction ecosystem for users.

Abstract

The rapidly evolving technology era demands a secure and efficient authentication mechanism when exchanging information between users and servers. One of the most common authentication methods used in REST APIs is JSON Web Token (JWT) due to its stateless and lightweight nature. However, the implementation of static JWT still has a weakness because pre-existing tokens can be used in other contexts such as other devices or other IP addresses. This can result in token misuse, resulting in data leakage. This study was conducted by comparing the performance and security aspects of static JWT and dynamic JWT in REST APIs using the PHP Laravel framework. Testing results show that the implementation of static and dynamic JWT does not have a significant difference in performance. However, dynamic JWT excels in security aspects because it is able to detect unauthorized access attempts due to context mismatch.

Abstract

The sharp price fluctuations in the cryptocurrency market, particularly in Bitcoin (BTC), create significant risks while simultaneously offering speculative profit potential for investors. Traditional analytical methods are often ineffective in detecting non-linear patterns present in stochastic financial time series data. This study proposes the application of a Deep Learning model utilizing the Long Short-Term Memory (LSTM) architecture to project the directional trend of Bitcoin prices (whether upward or downward) for the upcoming one-hour period. In the model's development, historical price data is integrated with a set of crucial technical variables, including the Relative Strength Index (RSI), Moving Average Convergence Divergence (MACD), and Exponential Moving Average (EMA), which serve as input attributes to enhance accuracy. Market data is retrieved in real-time via the Binance API, covering the last 1000 candlesticks. Experimental results using a Stacked LSTM architecture demonstrate that the model achieves an accuracy rate of 51.08% on the test data. Although this classification accuracy is considered moderate, a simple backtesting simulation indicates a positive profitability potential of 2.88% with a win rate of 48.39%. The output of this research also includes a web-based system prototype that integrates a Python backend with a visual interface for real-time monitoring of prediction signals.

Abstract

This study presents the development of a RESTful API service to support student schedule and attendance management in a higher education environment. The research is motivated by the fact that schedule management and attendance recording are often still handled manually or by stand-alone applications, which complicates recap processes, attendance monitoring, and integration with existing academic information systems. The proposed system is implemented using the Laravel framework and MySQL database, where student, lecturer, course, schedule, and attendance entities are modeled in a structured way and exposed through RESTful endpoints over HTTP with JSON data format. The research adopts a software engineering approach consisting of requirement analysis, system design, implementation, and testing using Postman on a local development environment. The experimental results show that all CRUD operations and attendance recording functions work as expected, producing consistent JSON responses with appropriate HTTP status codes, indicating that the developed API is suitable to be used as a foundation for future integration with web and mobile applications
