This study focuses on the development of an intelligent enemy behavior system in the 2D maze game Dungeon Escape by combining the A* algorithm for pathfinding and a Behavior Tree (BT) structure for decision-making. The main objective is to enhance Non-Playable Character (NPC) intelligence, enabling more adaptive and realistic interactions with players. The A* algorithm is implemented to allow NPCs to pursue players through the shortest and most efficient paths while avoiding obstacles on a grid-based map. Meanwhile, the Behavior Tree framework is designed to manage NPC actions based on dynamic conditions, such as attacking when in close proximity, chasing players within a certain detection radius, and retreating to the original guard position when the player leaves the active zone. The research methodology involves a comprehensive literature review, system design, and implementation using the Unity game engine. Testing procedures consist of both white-box and black-box approaches to evaluate the correctness, functionality, and efficiency of the system. The results indicate that all major game features—including player navigation, combat mechanics, key collection, enemy pathfinding, and user interface interactions—operate smoothly as expected. Furthermore, NPCs exhibit adaptive behavior by dynamically switching between patrolling, chasing, and attacking modes depending on the player’s location and proximity. Performance testing shows that the integrated A* and BT system runs efficiently without significant delays or instability, even in higher-level stages with more complex layouts. The final game prototype includes seven progressively challenging levels, offering players an engaging and dynamic gameplay experience. This study demonstrates that the combination of pathfinding and decision-making algorithms provides an effective solution for designing intelligent NPCs, improving both realism and entertainment value in 2D games. The findings are expected to serve as a useful reference for future research and development in AI-based game design, particularly in the context of Unity game projects.

Wireless Medical Sensor Networks (WMSNs) are a key component of modern Healthcare Internet of Things (IoT) systems, enabling continuous and real-time monitoring of patients’ physiological parameters. These networks support timely medical intervention, improve patient outcomes, and facilitate remote healthcare delivery. However, due to the open and resource-constrained nature of WMSNs, they are highly susceptible to various security threats, particularly during the authentication phase. Existing authentication protocols have been found vulnerable to a range of attacks, including impersonation, session key disclosure, and gateway database compromise, which can lead to severe privacy breaches and potentially life-threatening situations. To address these issues, this paper proposes a secure and lightweight three-factor authentication protocol tailored for WMSNs in healthcare IoT environments. The proposed protocol integrates Elliptic Curve Cryptography (ECC) for strong public key-based security with minimal computational overhead, fuzzy extractors to securely handle biometric information and ensure resistance against biometric template compromise, and session-based randomness to achieve forward secrecy and prevent replay or key-compromise impersonation attacks. Security analysis demonstrates that the proposed protocol successfully mitigates prominent threats such as impersonation attacks, man-in-the-middle attacks, session key leakage, and database compromise. In addition, the protocol ensures mutual authentication between the user, the gateway, and the sensor nodes, while maintaining data confidentiality and integrity. Performance evaluation indicates that the protocol offers significantly reduced computational cost and communication delay compared to existing schemes. Its low energy consumption and minimal storage requirements make it suitable for deployment in resource-constrained medical devices and large-scale IoT healthcare networks. The results highlight the protocol’s scalability, energy efficiency, and robustness, making it a practical and secure solution for safeguarding patient data and ensuring trustworthy communication in WMSNs-based healthcare IoT systems.

The rise in motor vehicle theft cases in various regions indicates the weakness of the security systems implemented by most users. Systems such as manual locks and alarms often fail to prevent crime, either because they are easily hacked conventionally or due to user negligence in their operation. In today's technological era, a system is needed that is not only secure, but also intelligent and practical. One promising solution is the implementation of a facial recognition-based security system. This study aims to design and test a vehicle security simulation system using facial recognition technology integrated with Arduino Uno and MATLAB. This system utilizes a laptop camera to capture the user's facial image, then performs a detection and verification process using the FaceNet algorithm. If the face is recognized and verified with data stored in the database, the Arduino will activate the actuator components in the form of a DC motor to simulate starting the engine, and a servo motor to simulate opening the vehicle door. This study uses a quantitative experimental approach to analyze the effect of variations in distance (30, 40, and 50 cm) and lighting brightness levels (10–20, 21–30, and 31–40 lux) on the system's response time. A total of 27 combinations of conditions were tested, and the data obtained were analyzed using Microsoft Excel and ANOVA tests in Minitab software. The results of the analysis showed that the optimal response time was obtained at a distance of 40 cm with a medium level of illumination (21–30 lux). In addition, both distance, brightness, and the interaction between the two factors were shown to have a significant effect on the system's response time (P-Value < 0.05). These findings indicate that the system is quite sensitive to environmental changes, so further testing is highly recommended, especially to measure the actual delay, the detection error rate, and the development of a more robust face detection algorithm so that the system can be used reliably in various lighting conditions and face capture angles in the real world.

In the customary law system, there is a pattern of punishment and prosecution which is more or less similar to the Islamic legal system, where the role of the victim's family is very important in determining whether or not the perpetrator will be prosecuted and punished. In customary law, legal settlements are carried out with an emphasis on togetherness or harmony. Settlement of criminal cases, especially bullying through customary law, is a process of resolving cases outside of court which consists of first, a mediation system with a consensus approach through deliberation. Second, the restorative justice system is a case resolution system with the aim of restoring the situation that arose for the victim so that a sense of brotherhood between each party is re-established. This system produces an agreement that is a win-win solution, guarantees the confidentiality of the parties' disputes, avoids delays caused by procedural and administrative matters, and resolves problems comprehensively together and while maintaining good relations. Thus, these customary sanctions do not provide legal protection and fulfillment of children's rights for children who are victims of sexual violence. In sexual crimes against children, children are positioned as victims who experience detrimental impacts, namely physical and psychological harm. Therefore, it is mandatory to be protected, not judged.

Public Fuel Filling Stations (SPBU) are important facilities that provide various types of fuel such as gasoline, diesel, and Pertamax to meet the needs of motorized vehicles. The existence of SPBU greatly helps the public in obtaining fuel at a more economical price compared to purchasing retail. However, the transaction system at SPBU generally still uses conventional methods, such as cash payments or the use of debit/credit cards that have not been fully integrated with an efficient digital system. The use of RFID (Radio Frequency Identification) technology has been implemented as a non-cash transaction method at several SPBUs, but this system still has various weaknesses, such as limited device compatibility and delays in transaction processing. This prompted the author to develop the concept of an independent SPBU based on modern technology that is more efficient and secure. The proposed innovation includes the use of contactless smart cards and coin acceptors for the payment system, allowing users to make self-service transactions without operator involvement. In addition, the author also added several supporting components such as proximity sensors, which function to detect the presence of vehicles or people around the SPBU area. These sensors can help in saving electrical energy by activating the system only when needed. Another component is a vibration sensor, which plays a crucial role in detecting excessive vibrations that could potentially cause leaks. If excessive vibration is detected, the system automatically closes the solenoid on the pump to prevent the risk of fire or damage. By integrating this technology, the autonomous gas station system is expected to improve operational efficiency, user convenience, and safety during the automatic refueling process. This development is expected to be an innovative solution for modernizing the gas station system in Indonesia.

Building Information Modeling (BIM) is a technology increasingly used in the modern construction industry, particularly to improve communication efficiency and collaboration between stakeholders. This technology enables the integration of project data and information into a comprehensive digital model, allowing all involved parties to access, verify, and update information in real time. This study aims to evaluate the strategic role of BIM as a communication medium in the Integrated Project Delivery (IPD) approach, focusing on the planning stage involving the disciplines of architecture, structure, and Mechanical, Electrical, and Plumbing (MEP) systems. The IPD approach emphasizes cross-disciplinary collaboration from the early stages of a project to optimize outcomes, reduce risks, and accelerate completion. The research methods used are literature review and case study analysis of various projects that have implemented BIM within the IPD framework. The data analyzed include the effectiveness of information exchange, inter-team coordination, and early identification of design conflicts. The study results show that BIM significantly improves information transparency among stakeholders, minimizes the risk of miscommunication, and accelerates the decision-making process through accurate and integrated data visualization. BIM models also facilitate the detection of potential conflicts, such as clashes between structural and MEP elements, before entering the physical construction phase, thereby reducing repair costs and delays. Furthermore, the use of BIM in IPD fosters a more collaborative work culture, where architects, engineers, and contractors can work together to solve problems quickly and effectively. Thus, BIM has proven to play a crucial role as a primary communication tool in IPD implementation, while also serving as a crucial foundation for achieving efficient, integrated, and high-quality construction project management.

This study addresses the issue of unit delays in providing goods receipt notes and routine distribution of supplies to the general logistics department, which impacts the inefficiency of the non-medical logistics management process at Ibnu Sina General Hospital, Bukittinggi. Untimely logistics management can hamper the availability of goods, disrupt the smoothness of services, and increase the risk of stock outs. The purpose of this study is to obtain a comprehensive overview of non-medical logistics management at the hospital, particularly in the aspects of planning, procurement, and control. The research method used is descriptive qualitative with in-depth interviews with five informants. The research informants include Mrs. D as triangulation, Mr. Y and Mr. B as general logistics staff, and Mrs. D and Mrs. S as unit staff. Data were analyzed to identify patterns and obstacles that occur in the non-medical logistics management process. The results show that the entire non-medical logistics management process at Ibnu Sina General Hospital, Bukittinggi is guided by requests from the unit. Logistics planning is carried out based on the receipt notes submitted by the unit, procurement can only be carried out after the receipt notes are received, and stock control is carried out by summarizing requests in the stock card. Although the procedures complied with the Standard Operating Procedures (SOPs) established by the hospital director, obstacles were identified, including delays in unit submissions and weak stock control at the unit level. This situation has the potential to lead to management inefficiencies and stockouts. The conclusion of this study confirms that the non-medical logistics management system at Ibnu Sina Islamic Hospital, Bukittinggi, complies with SOPs. However, improvements in timeliness in submitting orders and strengthening stock control within the units are needed to optimize logistics management efficiency.

Epilepsy is a chronic neurological disorder characterized by recurrent seizures due to abnormal electrical activity in the brain. This condition can significantly impact the quality of life of sufferers, making the development of effective and safe anticonvulsant therapies a priority in pharmacological research. This study aimed to evaluate the effectiveness of various anticonvulsant drugs, including herbal candidates, in a mouse model (Mus musculus) using acute and subchronic test protocols. Seizures were induced by administering strychnine, a glycine receptor antagonist that triggers excessive neuronal excitability. Parameters observed included seizure onset (the time from strychnine administration to the onset of the first seizure) and deadtime (the time of survival after a seizure). The study involved six treatment groups: a negative control (Na-CMC), four conventional drug groups (phenytoin, diazepam, pregabalin, and gabapentin), and one herbal candidate group made from Polyalthia longifolia (glodokan tiang). The results showed that most treatment groups were able to delay seizure onset and significantly prolong deadtime compared to the negative control. Statistical analysis using ANOVA yielded a p-value <0.05, indicating a significant difference between groups. The herbal candidate Polyalthia longifolia showed promising anticonvulsant potential, although it did not fully match the effectiveness of conventional drugs such as phenytoin or diazepam. The negative control (Na-CMC) showed the fastest onset and shortest survival time, reflecting the absence of a protective effect against seizures. This study emphasizes the importance of further testing using chronic protocols and evaluating additional parameters such as plasma drug concentrations and neurological side effect profiles. The obtained data are expected to form the basis for the development of anticonvulsant therapies based on a combination of modern drugs and natural ingredients, with the hope of producing safer, more effective treatment alternatives, and potentially reducing dependence on long-term synthetic drugs.
