Contract law serves as a fundamental pillar of the modern legal system, regulating relationships and interactions between parties involved in various economic and business transactions. A contract functions as a legal instrument that ensures certainty, fairness, and the protection of rights and obligations among the parties. This paper provides an in-depth analysis of the essential principles of contract law, such as the principles of freedom of contract, consensualism, good faith, and pacta sunt servanda, as well as their practical implementation within the Indonesian business context. Furthermore, this study discusses common challenges in the application of contract law, including unequal bargaining positions, contract breaches, and difficulties in law enforcement. The discussion also explores mechanisms for resolving contractual disputes, both through litigation and alternative dispute resolution methods such as mediation and arbitration. This research aims to provide a comprehensive understanding of how contract law functions not only as a binding legal framework but also as an instrument to promote equitable, transparent, and sustainable business relationships.

This research discusses the Constitutional Court Decision Number 90/PUU-XXI/2023 regarding the minimum age requirement for presidential and vice-presidential candidates as stipulated in Article 169 letter q of Law Number 7 of 2017 concerning General Elections. In that decision, the Constitutional Court ruled that the age limit of 40 years remains in effect, but with an exception for candidates who are not yet 40 years old but have previously or are currently serving as regional heads. This research employs a normative juridical method with legislative and conceptual approaches, analyzing primary legal materials such as the 1945 Constitution, Election Law, and Constitutional Court decisions, supported by secondary legal materials from academic literature and journals. The research findings indicate that the Constitutional Court's considerations are based on the principles of citizens' constitutional rights, open legal policy, and the idea of leadership experience as an alternative age requirement. This decision has positive implications, including opportunities for leadership regeneration and increased political participation by young people, but it also draws criticism for its potential to discriminate against non-regional leaders and create political suspicion. Therefore, a revision of the Election Law is needed to clarify the legal norms resulting from the Constitutional Court's decision so that it does not lead to multiple interpretations and maintains the principle of equality. This research concludes that the Constitutional Court's decision is an opportunity to strengthen democracy, but also a challenge in ensuring constitutional justice in Indonesia.

This study aims to analyze how Islamic education policy in Indonesia functions as a social mechanism in shaping and maintaining societal integration amidst modern social change. Based on Émile Durkheim's functionalism theory, this study views Islamic education as an institution that plays a vital role in maintaining moral order, social solidarity, and preventing symptoms of anomie resulting from an imbalance between traditional values and the demands of modernity. The approach used is qualitative with an exploratory-descriptive orientation, with data collection techniques through literature studies of policy documents, institutional reports, and related scientific research results. The analysis is conducted descriptively and analytically to interpret the social function of the policy based on the concepts of social solidarity, division of labor, and anomie. The results show that policies such as madrasah integration, religious moderation programs, and teacher professionalization have a manifest function in expanding access to education, increasing social mobility, strengthening gender equality, and strengthening cohesion between religious communities. However, latent functions are also found in the form of bureaucratization of educational institutions, resource inequality, and value resistance among local communities. These findings confirm that Islamic education policy operates ambivalently: as an integrative instrument that strengthens social solidarity, but also as an arena for value negotiation between tradition and modernity. Therefore, Islamic education policy needs to be directed in a more contextual and participatory manner to optimally function as an agent of inclusive, adaptive, and sustainable social transformation for modern Indonesian society.

This research confirms that online business readiness is not only determined by technical skills, but also by the strengthening of an adaptive, innovative digital mindset. This research confirms that online business readiness is not only determined by technical skills, but also by strengthening an adaptive, innovative, and resilient digital mindset.The novelty of this research is the integration of TPB and Entrepreneurial Mindset Theory to understand students' readiness to face digital business challenges.

The limitation of physical memory (RAM) is a primary constraint hindering optimal performance in modern operating systems, especially when running large applications or performing intensive multitasking, often resulting in crashes and high latency. This research aims to quantitatively analyze the effectiveness of Virtual Memory (VM) implementation as a solution to this RAM constraint on the Windows 10 operating system, focusing on VM’s impact on CPU performance, GPU performance, and multitasking response. The methodology employed is a controlled experiment using industry-standard benchmarks: Cinebench R20 (CPU), Unigine Heaven (GPU), and response time measurements in intensive multitasking scenarios. Experimental results demonstrate that VM activation improves CPU/GPU performance by up to 5% and accelerates multitasking response time by up to 15%, confirming VM's effectiveness in mitigating memory bottlenecks. Nevertheless, this study also identifies potential performance overhead stemming from excessive paging and swapping processes, which trigger the phenomenon of Thrashing. Therefore, the research recommends a dual optimization strategy to achieve maximum and stable performance: software optimization via the Least Recently Used (LRU) algorithm to suppress page faults, supported by hardware optimization including the use of an SSD for the swap file and increased RAM capacity.

The development of embedded sistem technology is now widely used to support automatic environmental data recording processes, such as temperature, humidity, and air pressure. However, most existing weather data loggers still operate independently and are not directly connected to a computer. As a result, data collection and processing must be done manually, which is less efficient and prone to data loss. The main problem in this research is the lack of integration between microcontroller-based data loggers and simple computer operating sistems such as the Disk Operating Sistem (DOS), making it difficult to automatically store and access recorded data. This study aims to develop an embedded weather data logger sistem based on the AVR microcontroller integrated with DOS. The development process uses the waterfall model, consisting of sistem planning, requirement analysis, sistem design, coding, testing, and implementation. The designed sistem records weather parameters in real time and stores them in a file format that can be directly read by DOS without requiring additional conversion processes. The test results show that the sistem runs stably, records data accurately, and can be easily accessed through a computer. Integration with DOS allows data storage and retrieval processes to be faster and more efficient. Therefore, this sistem provides a practical solution for automatic weather monitoring that is reliable, time-saving, and easy to use in various environmental conditions.

in private junior high schools throughout Sempu District, female students follow Physical Education, Sports, and Health (PJOK) learning with feelings of boredom, doubt, and difficulty. However, it is not yet known what level of motivation female students have in following Physical Education, Sports, and Health (PJOK).  This study aims to analyze the motivation level of female students in participating in Physical Education, Sports, and Health (PJOK) learning at private junior high schools in Sempu District, Banyuwangi Regency. The research employs a survey method with a descriptive quantitative approach. Data were collected through questionnaires distributed to 62 respondents and analyzed using descriptive statistics with the assistance of SPSS software. The findings indicate that students' motivation in PJOK learning is generally high, with an actual score of 4,637 out of an ideal score of 6,200. The obtained mean score is 3.738, with a Respondent Achievement Level (TCR) of 74.79. Although most indicators reflect a high level of motivation, certain aspects remain in the moderate category, such as indicators X11, X16, X18, and X20. Factors contributing to lower motivation in these aspects may include a lack of variation in teaching methods, limited sports facilities, and insufficient external support. Therefore, efforts to enhance motivation should include more interactive teaching methods, improved sports facilities, and stronger environmental support to further increase students' enthusiasm for PJOK learning.

Regular exercise plays a crucial role in maintaining and improving immune system function, especially in female athletes who experience hormonal and physiological stress during training. This review article aims to explain the effects of aerobic and anaerobic exercise on humoral immune parameters and stress hormone responses in female athletes compared to inactive women. Based on the results of various studies, moderate and consistent physical activity can increase levels of immunoglobulins (IgA, IgG, and IgM) and strengthen immune protection. On the other hand, high-intensity or excessive exercise can increase cortisol and ACTH levels, potentially suppressing immune function temporarily. Research findings also show that female athletes have a better immune profile compared to inactive women, as indicated by increased natural killer cell activity and lymphocyte proliferation. However, excessive exercise can lead to immunological imbalance. Therefore, moderate-intensity exercise and well-planned training programs are proven to maintain endurance and prevent the risk of immune decline. This review is expected to broaden the understanding of sports immunology and women's health.

In the modern industrial world, robots like mechanical arms in automotive factories or packaging lines must move quickly and safely. For this, a real-time operating sistem (RTOS) is needed—think of it as a "super-fast brain" that ensures the robot reacts instantly to commands, without delays or errors. This paper analyzes popular RTOS like FreeRTOS and VxWorks for controlling industrial robots, focusing on evaluating performance (speed of operation) and stability (long-term reliability). We conducted tests in a lab using a simple robot that moves its arm to pick up objects. Performance was measured by response time (how quickly the robot stops when encountering an obstacle, ideally under 10 milliseconds) and throughput (how many tasks it can complete per second). Stability was checked through simulations of disruptions, like heavy loads or interfered sensor signals, using metrics such as error rate and time variation (jitter). Results show that FreeRTOS is more efficient for small, affordable robots, with high performance (average response time of 4 ms) but moderate stability (5-10% errors during overload). In contrast, VxWorks excels in stability (errors <2%, stable for up to 95% of tasks on time) for large factory robots, though it requires stronger hardware. Our analysis uses simple models like graphs and repeated tests, without complex formulas, to prove that the right RTOS can boost production efficiency by up to 25% and reduce accident risks.

Android continues to innovate, and biometric systems particularly fingerprint sensors must operate with high efficiency. However, the main challenge lies in the communication between hardware and software, which often causes high latency, excessive power consumption, and protocol incompatibility between components. As a result, authentication speed decreases and system stability is compromised, especially on mid- to low-range devices. This study explores various implementations of Android-based fingerprint systems, focusing on how sensor modules interact with the microcontroller or Trusted Execution Environment (TEE) and the operating system through a hardware-software co-design approach to evaluate integration efficiency across all layers. The analysis reveals that conventional protocols such as Bluetooth or serial connections still cause delays, while improvements in drivers and the Hardware Abstraction Layer (HAL) can significantly reduce latency. As a solution, the researchers propose a co-design optimization approach that utilizes data flow normalization within the HAL and adopts lightweight communication protocols to accelerate the verification process. Based on the test results, this approach successfully improves efficiency—authentication time is reduced by up to 35% and power consumption decreases by approximately 15%. Therefore, the efficiency of communication between hardware and software becomes a key factor in enhancing the performance and reliability of fingerprint systems on Android devices.

The synchronization of mutex and semaphore mechanisms is an important technique in operating systems for managing concurrent resource access in multi-threaded environments. In the Android operating system, which relies on thread-based programming to maintain performance and responsiveness, these two mechanisms play a vital role in preventing race conditions and ensuring data integrity. A mutex is a locking object that ensures that only one thread can access a specific resource at a time, while a semaphore controls access to a limited number of resources by counting the number of threads that can access them simultaneously. In Android, these mechanisms are implemented using the Lock class for mutexes and the Semaphore class for semaphores, both of which can be used to control synchronization between threads in Android applications. This paper will discuss the application of these two mechanisms in the context of shared resource management, as well as a comparison of their performance and advantages in dealing with complex multi-threading scenarios on Android. Emphasis will also be placed on the challenges faced in using these two mechanisms in Android applications, as well as how proper programming can avoid deadlocks and improve application efficiency.

In conclusion, strengthening leadership vision is essential to ensure the sustainability and relevance of Islamic education in the modern era.

Indonesia is a large archipelagic country with significant fisheries potential. However, fish resources in Indonesian waters have shown a declining trend over the past decade. This decline is caused by various factors, including the deterioration of coastal environmental quality due to human activities that pollute the sea, destructive fishing practices, and excessive exploitation or overfishing. This study aims to analyze the utilization rate of bigeye tuna in FMA-NRI 573 landed at PPS Nizam Zachman and to provide recommendations for the utilization efforts of bigeye tuna in FMA-NRI 573 landed at PPS Nizam Zachman. The utilization rate of fish can be calculated by comparing the total catch to the maxmimum sustainable yield (CMSY) using the formula TPc=(Ci/CMSY)×100%TP_c = (C_i / C_{MSY}) \times 100\%TPc=(Ci/CMSY)×100%. The utilization rate obtained, with an average CMSY of 846,325, falls under the category of Lightly Exploited according to FAO and Moderately Exploited based on Ministerial Regulation KP No. 22/2021. This indicates that the utilization is still relatively low or minimal. Therefore, it is necessary to conduct a review of existing fishing regulations in order to maintain the potential sustainability of capture fisheries.

Mobile navigation interfaces continue to be plagued by a key usability problem, particularly when widely accepted design traditions fail to address the specific requirements and mental models of local user populations. This research addresses this significant limitation by using a comprehensive user-focused measurement framework to identify and investigate context-dependent navigation problems in mobile applications. The research employed a multi-method qualitative approach, using in-depth questionnaires, semi-structured interviews, and laboratory-based usability testing of 15 participants on an interactive Figma prototype that simulated real-world navigation tasks. Our analysis, step by step, revealed significant navigation issues in the local context, as evidenced by a 73% task-completion rate and an average participant error of 2.8 across the core navigation tasks. The most significant usability issues were ambiguous iconography, inconsistent application of platform design patterns, and insufficient system feedback mechanisms. The results conclusively demonstrate that localized usability testing is not merely beneficial but necessary while creating genuinely good and accessible mobile experiences. The study provides a replicable, practical context-aware evaluation approach and tangible, right-now-applicable design recommendations, such as enhancing icons with descriptive text labels and using instant visual feedback mechanisms. The study provides developers and designers with tangible takeaways for significantly enhancing navigation user experience without sacrificing methodological availability or implementation convenience across different development environments.
