Abstract

ABSTRACTIn IP-based networks with many users, a bandwidth usage regulation mechanism is needed to ensure service quality. Mikrotik RouterOS has a feature to run QoS known as queue. RouterOS uses the Hierarchichal Token Bucket (HTB) method as the main queue method. The results of the tests carried out show that HTB is able to provide traffic limitation facilities for each classification and guarantee or ensure the amount of bandwidth is less or equal to the predetermined amount. If there is unused bandwidth it can be used by a lower classification (borrowing mechanism).

Abstract

Communication security in Wireless Sensor Networks (WSNs) is a significant challenge in the implementation of the Internet of Things (IoT), particularly in smart city applications which have limitations in energy, memory, and computation. Conventional cryptographic algorithms are generally not suitable for IoT devices due to their complexity and high resource requirements, necessitating lightweight cryptography (LWC) algorithms that can balance security and efficiency. This research evaluates three lightweight encryption algorithms - Speck, Simon, and Ascon - using NS-3 simulations in a multi-hop network scenario with 30 nodes. The parameters analyzed include energy consumption, encryption/decryption time, and communication overhead. The simulation results show a significant trade-off: Speck and Simon excel in energy efficiency and low latency, but their security level is moderate; while Ascon provides stronger security according to NIST LWC standards, but with the consequence of higher energy consumption. The main contribution of this research is the provision of a reproducible NS-3 simulation-based framework that can link security and energy efficiency aspects, while also filling the literature gap, which is still limited to hardware testing. This finding is expected to serve as a practical reference for IoT system designers in determining the appropriate encryption algorithm for smart city application needs, and to open up opportunities for further research on real IoT devices.

Abstract

The digital transformation in higher education demands facility management systems that are efficient, transparent, and user-oriented. This is especially important for computer laboratory reservations, which are more complex technically and administratively than standard classroom bookings. At the Vocational School of IPB University, the manual reservation workflow caused schedule conflicts, limited visibility of availability, and difficulties in managing laboratories across multiple locations. This study aims to design and develop a web-based laboratory reservation system. The goal is to improve service effectiveness and user interaction by applying Design Science Research (DSR) methodology (a framework for creating and evaluating IT solutions) together with User-Centered Design (UCD) principles (methods focused on user needs and experience). System development included requirements analysis, Unified Modeling Language (UML—a system design notation), and UCD-based interface design, iterative prototyping, and both functional and usability evaluation. Black Box Testing (a method of checking that all features work as specified) showed 100% feature conformity, including a schedule-locking mechanism to prevent double booking. Usability was assessed using the System Usability Scale (SUS—a standard survey for usability), yielding a score of 82.3 (Excellent). This was accompanied by a 45% improvement in reservation efficiency compared to manual procedures. The findings demonstrate that the proposed system enhances administrative efficiency, improves transparency in room availability, and enhances the user experience. Academically, this work contributes a validated DSR–UCD model for usability-driven system development. Practically, it offers a scalable and replicable solution for managing laboratory reservations in multi-location vocational education environments.

Abstract

Dissolved Oxygen (DO) is an important parameter for maintaining water quality in aquaculture systems. The accuracy of DO sensors significantly affects the reliability of Internet of Things (IoT)-based monitoring systems. This study aimed to calibrate the DO sensor using a two-point calibration method and evaluate the accuracy of the sensor readings compared with those of a reference device (standard DO meter). A key novelty of this study lies in its multi-media calibration, performed directly on six distinct aquaculture water types, providing field-realistic validation conditions not commonly explored in previous studies. Furthermore, the accuracy of the calibrated sensor is evaluated quantitatively using MAE, RMSE, and percentage deviation to ensure rigorous performance assessment. The system was developed using an ESP32 microcontroller, DO sensor (SEN0237), DS18B20 temperature sensor, and ADS1115 ADC module. Testing was performed on six types of aquaculture water media and compared with a standard DO meter using a comparative approach. In total, n = 6 field measurement points (one stabilized reading per water medium) were used to compute MAE, RMSE, and percentage deviation. The comparison results showed that the calibrated sensor had high accuracy, with a Mean Absolute Error (MAE) of 0.1083 mg/L and a Root Mean Square Error (RMSE) of 0.2654 mg/L. Significant deviations occurred only in one type of water medium, whereas the other five showed results consistent with the reference device, indicating stable sensor readings. These findings confirm that proper calibration can improve the accuracy and reliability of IoT systems used for water-quality monitoring. Regular calibration is required to maintain the sensor performance, particularly for long-term use in dynamic aquaculture water environments.
