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.

Motor development in infants is a crucial process that occurs gradually and follows the principles of age-appropriate development. Each fundamental motor stage—such as tummy time, rolling over, sitting, crawling, standing, and walking—must be passed through sequentially to ensure optimal motor concept development. Skipping or insufficient stimulation of these stages may lead to difficulties in understanding functional body movements. One of the main causes of delayed motor development includes a lack of motor stimulation time, overly restrictive parental supervision, and low levels of motivation and stimulation provided to the child. Tummy time, or placing the baby in a prone position while awake, is a proven effective form of motor stimulation that supports the development of the baby’s neck, back, and arm muscles. This activity also assists infants in reaching subsequent developmental milestones such as rolling over and crawling. This Community Service Program (PkM) was conducted at the Physioroom Clinic and was attended by 15 mothers with infants aged 3 to 6 months. The objective of the program was to enhance mothers’ knowledge regarding the importance of tummy time in supporting infant motor development. The program's implementation included educational sessions, tummy time practice demonstrations, group discussions, and interactive Q&A sessions. To measure the increase in participant knowledge, a pre-test and post-test were administered before and after the activity.The results of this PkM activity showed an increase in the average knowledge score from 6.4 in the pre-test to 8.6 in the post-test. This improvement demonstrates the program’s effectiveness in educating mothers about the benefits of tummy time for infant motor development. It is hoped that the mothers will consistently apply this stimulation at home to optimally support their children's growth and development.

Murals are positioned as texts that communicate social messages through a combination of visual and symbolic, and act as a medium for environmental advocacy in public spaces. This study discusses the mural design with the theme "The Impact of Vehicle Pollution on Public Health" as a form of visual language analyzed through M.A.K. Halliday's systemic functional linguistic approach, especially in the aspect of the situational context consisting of field, tenor, and mode. This analysis shows that the mural field reflects environmental issues and their impact on public health. The participants in this study include artists as message makers and the wider community as audiences; while the mode relies on strong visual images, symbolic colors, and text elements to strengthen the message. The results of the study reveal that this mural design not only functions as an artistic expression, but also as a means to build effective social awareness through visual strategies. This study emphasizes that understanding the situational context of mural design is very important for interpreting the message conveyed more deeply and critically to society.

This study aims to examine the regulatory framework concerning Government Employees with Work Agreements (PPPK), particularly in Functional Expert Positions in Indonesia and to identify how the policy implementation of PPPK in Functional Expert Positions is carried out at the Constitutional Court. The research employs an empirical method with a qualitative approach. The types of data used include both primary and secondary data: primary data was obtained through field interviews, while secondary data consists of documents, information, books, and facts sourced from official records and legislation. The findings of this study indicate that the implementation of policies related to Functional Expert Positions at the Constitutional Court still faces regulatory inconsistencies, especially in the selection mechanism, which does not fully adhere to the established rules. Additionally, competency development for PPPK employees is not supported by systematic planning, which risks creating skill gaps. This situation may lead to uncertainty in career progression and reflects that the management of PPPK still encounters several fundamental challenges in its implementation.  

Credit score evaluation for functional positions is a critical component in the career development of employees at the Financial Supervisory Agency (BPK) in Jakarta. However, this evaluation process often encounters challenges related to objectivity, consistency, and transparency due to the combination of qualitative and quantitative criteria. This study aims to apply the Analytical Hierarchy Process (AHP) as a decision support tool in the credit score assessment system. AHP is chosen for its ability to break down complex problems into a hierarchical structure and to assign priority weights through pairwise comparisons among criteria. This method is used to determine the priority weights of each evaluation component, including both main and supporting elements, leading to more structured and accountable decisions. The findings indicate that the implementation of AHP enhances the accuracy and objectivity of the credit score evaluation process for functional positions at BPK. Therefore, this approach can serve as the foundation for developing a more transparent and efficient technology-based assessment system.

The competitiveness of Micro, Small, and Medium Enterprises (MSMEs) in Indonesia often faces obstacles due to limited product packaging that fails to adequately reflect product quality, uniqueness, and brand identity. Packaging is not merely a protective container but also a strategic communication tool that influences consumer perceptions, shapes brand image, and supports market expansion. This community service program was carried out at the Banana Chips MSME “Bu Tini” in Semarang, which previously relied on simple plastic packaging without graphic design, brand logo, or product information. The main objective of this program was to assist the MSME in developing both the design and functional aspects of packaging as a strategic effort to strengthen branding, enhance product value, and improve competitiveness. The methodology applied was community-based and participatory, consisting of field observation, focus group discussions, collaborative design with the business owner, and prototype testing of new packaging. The results demonstrate that the redesigned packaging highlights a stronger visual identity through logos, colors, and slogans, while also ensuring practicality, durability, and compliance with food safety standards. Furthermore, the new packaging improved information clarity regarding composition, expiration date, and producer details, which significantly increased consumer trust in hygiene and quality. From a broader perspective, the activity fostered social transformation by raising awareness among the owner and workers about the importance of branding and professional packaging, developing new skills, and positioning the MSME as a role model for similar businesses in the community. This program implies that packaging development is not solely a visual improvement but a strategic branding instrument that can support MSMEs in achieving sustainability and greater competitiveness in local, regional, and potentially digital markets.

Automatic Identification System (AIS) is a communication technology that plays an important role in improving operational safety and efficiency in the shipping industry. AIS allows ships to exchange real-time data on identity, position, speed, and direction, which helps prevent collisions and facilitates maritime traffic management by port authorities. In addition, AIS functions in search and rescue operations by providing accurate information on the location of ships in trouble. In terms of security, AIS allows monitoring of suspicious ships, thus helping in preventing illegal activities in the waters. This study aims to design and develop a prototype AIS receiver based on LoRa, Arduino, and LCD HMI. The LoRa module was chosen because of its ability to transmit data over long distances with low power consumption, which is suitable for the maritime environment. Arduino is used as the main microcontroller to control the system, while the LCD HMI serves as the display interface for the received data. After the hardware and software design was completed, the system was tested through functional testing and performance measurements using a spectrum analyzer to evaluate the strength of the LoRa signal at various distances. The test results show that the AIS receiver is able to receive data well up to 15 meters on land and 13 meters at sea, with a delay of 100 milliseconds. System performance degrades at longer distances due to environmental interference and signal attenuation. These findings provide insight into the effective limits of LoRa communication in maritime applications and can be used as a reference for frequency testing and optimization of LoRa-based long-range communication systems.

This research aims to analyze how the church in the old and new testaments. The approach used in this research is descriptive qualitative, which aims to understand the structure so that it has a major influence on contemporary Christianity. From a conceptual perspective, the Church in the Old Testament is understood as a community of God's chosen people whose identity is attached to the ethnic unity of the Israelites and attachment to the law within the framework of the covenant. While in the New Testament, the understanding of the Church undergoes a transformation into a universal, inclusive, and spiritual community of faith, consisting of all people who believe in Jesus Christ as Lord and Savior, without ethnic or legal restrictions. In terms of structure and leadership, the Old Testament features a leadership system based on heredity and institutional positions such as priests and prophets who mediate the people's relationship with God; whereas in the New Testament, leadership is no longer hereditary, but based on the gift of the Holy Spirit, with a collegial, functional and participatory service model and Christ as the Head of the Church, emphasizing the dimensions of relationships and service in the community.In terms of sacraments, religious practices in the Old Testament such as religious celebrations functioned as symbols of obedience and identity of the people's covenant with God, but in the New Testament, so the sacramental meaning is renewed through baptism and holy communion which are spiritual and Christocentric, marking new fellowship in Christ in the context of grace. This study concludes that the New Testament cannot be understood as a break with or an abolition of the traditions and practices that existed in the Old Testament. Instead, the New Testament represents a theological fulfillment and essential transformation of the entire narrative and system that had been built in the Old Testament.

Benign paroxysmal positional vertigo (BPPV) is a common cause of peripheral vestibular dysfunction, often resolving with canalith repositioning maneuvers (CRM). However, residual dizziness and imbalance may persist, impairing functional mobility. This case report describes a 55 year old female diagnosed with right posterior canal BPPV through a positive Dix Hallpike test. Following successful CRM, she reported residual postural instability and difficulty walking. A structured four week vestibular rehabilitation therapy (VRT) program was implemented, consisting of habituation (Brandt Daroff), adaptation (gaze stability, VOR x1, VOR x2), sensory substitution, and progressive balance training, delivered three times weekly for 45 minutes per session. Balance and mobility were assessed using the Berg Balance Scale (BBS) and Timed Up and Go (TUG) test at baseline and after the intervention. Results showed improvement in BBS from 42/56 to 53/56 (+11 points) and a reduction in TUG from 14.8 to 9.6 seconds (−5.2 seconds), both exceeding minimal detectable change values for older adults. The patient reported complete resolution of dizziness, increased walking confidence, and return to independent daily activities without adverse effects. This case suggests VRT as a valuable adjunct to CRM in BPPV patients with residual functional deficits, warranting further research in larger controlled studies.

This paper presents an IoT-enabled dual-axis solar tracking system that integrates  a Kalman filter and a Proportional-Integral-Derivative (PID) controller to enhance tracking accuracy, energy efficiency, and operational stability. Addressing the ongoing challenge of maxi- mizing photovoltaic (PV) panel output, the proposed system leverages an ESP32 microcontroller and the Blynk platform to provide real-time monitoring, remote parameter adjustments, and flexible connectivity. Light Dependent Resistor (LDR) sensors measure sunlight intensity from multiple directions, while MG90S servo motors dynamically adjust the panel’s azimuth and elevation. The Kalman filter refines noisy sensor data to yield precise sun position estimates, enabling the PID controller to respond quickly and accurately to deviations in panel orientation. Through extensive testing conducted over several days, including both clear and partially cloudy conditions, the system achieved an average Root Mean Square Error (RMSE) as low as 1.2° under clear skies and maintained RMSE below 2.0° even under partial shading. Compared to a fixed-panel baseline, daily energy harvesting improved by approximately 43%. These results confirm that advanced estimation and control algorithms, when combined with IoT functionali- ties, significantly outperform simpler tracking methods and static installations. Furthermore, the low-cost, compact design and user-friendly interface facilitate practical deployment in a range of scenarios, including small-scale and off-grid installations. By ensuring continuous alignment of the PV panel with the sun, the system not only increases overall energy capture but also reduces maintenance requirements through remote oversight. This research thus offers a robust, scalable approach to improving solar energy utilization in diverse and evolving environmental conditions.

This article explores the mechanisms of supervision and legal protection within state administration. Ensuring legal protection for citizens is a vital aspect of governance in democratic nations. Laws serve as tools to regulate rights, obligations, and legal entities, enabling them to fulfill their duties and receive fair treatment. Additionally, the law functions as a protective framework for legal subjects. The legal relationship between the state and its citizens can be governed either by state administrative law or civil law, depending on the state's role and position in upholding the law. The government may act as a civil legal entity or a public official, subjecting its legal actions to either the Civil Code or state administrative law. Mechanisms for supervision and legal protection in state administration include embedded supervision, functional supervision, and external supervision. Furthermore, citizens are afforded legal protection through administrative law mechanisms such as administrative law provisions, administrative appeals, and administrative courts.

This study is motivated by the status of Surah Yusuf as ahsanul qashash, which has special characteristics in terms of balagah, particularly the use of kinayah to convey sensitive narratives in a polite manner. This study aims to identify the classification of types of kinayah and reveal the pragmatic functions behind their use in the text. The research method used is descriptive qualitative with heuristic-semiotic analysis techniques, where the primary data is sourced directly from the verses of the Qur'an. Surah Yusuf predominantly uses kinayah 'an al-maushuf to refer to certain entities or positions in order to maintain the dignity of the narrative, in addition to the use of kinayah shifah and nisbah to describe the emotional turmoil of the characters. Functionally, this style of language plays the role of ihtiraz (preventive), mubalaghah (emphasis of meaning), and ta'dzim (respect). The implications of this study confirm that the use of kinayah is not merely linguistic aesthetics, but a medium of moral education that promotes polite interpersonal communication and is relevant to contemporary Islamic ethics.

This study aims to examine the implementation of the bureaucratic simplification policy by equating administrative positions to functional positions in the West Bandung Regency Regional Secretariat.
