General elections for the legislature are significant junctures in the political process because they involve the community in choosing its legislators. The city of Bengkulu held engaging legislative elections between 2014 and 2019, which are worth studying and analysing in the perspective of civic engagement. Both qualitative and quantitative research methodologies were used in this study. The political engagement of the electorate in the legislative elections in Bengkulu City saw numerous dynamics and changes between 2014 and 2019. Political campaigns run by legislative candidates can also have an impact on levels of political involvement. If the campaign fails to inspire and influence the electorate to vote in the 2019 election, political engagement may decline. Analysing political involvement is crucial for evaluating Bengkulu City's level of democracy and political representation. The degree of public confidence in the political process and candidates for public office is demonstrated by the amount of political involvement. The public's apathy and discontent with the political system may also be raised by poor political involvement.

Sports education has learning characteristics that are different from other subjects because it is more psychomotor in nature and still involves affective and cognitive abilities that are comparable to learning those who mainly move. Students are expected to be able to improve affective and cognitive skills with learning modifications that have been arranged by the teacher. The same goes for encouraging healthy living habits through sports education. By banning students from the values of healthy living habits, sports education can become the foundation for a complex of knowledge that will help students maintain their quality of life into old age. Health is a fundamental need in life. The majority of individuals frequently disregard the behavior needed to establish a culture of healthy living. To create good quality human beings in terms of physical, mental and spiritual development, it is crucial to promote a culture of healthy living. The government and people who care about health must continue to step up their efforts to better understand each person in order to develop a perspective that can shift behavior in a positive direction. It is believed that through physical, sports and health education in educational institutions, children will develop a healthy lifestyle culture from an early age.

Long-term forecasting of earthquake magnitudes plays a vital role in seismic hazard assessment and disaster mitigation, particularly in highly active seismic regions such as Bengkulu, Indonesia. This study introduces a probabilistic framework based on the stationary distribution of discrete-time Markov chains to predict the likelihood of various earthquake magnitudes over an extended period. Historical earthquake records from Bengkulu are categorized into discrete magnitude classes to form the states of the Markov chain. Transition probabilities between these states are estimated from the data, allowing for the construction of a transition matrix that accurately reflects the temporal dynamics of seismic activity. By analyzing the stationary distribution of this Markov chain, we derive the long-term probabilities of occurrence for each magnitude class, revealing inherent patterns in earthquake magnitudes that are otherwise difficult to capture with traditional methods. The stationary distribution serves as a stable, time-independent descriptor of the seismic regime, providing insights into the expected distribution of earthquake magnitudes in the future. The results indicate that this approach not only captures the probabilistic behaviour of seismic magnitudes but also offers a computationally efficient and interpretable model for earthquake forecasting. This modelling technique complements existing seismic hazard assessments and has practical implications for risk management and emergency preparedness in Bengkulu and other seismically active areas. Future research will explore the integration of spatial factors and earthquake depth to further enhance prediction accuracy.

Knapsack Problemis one of the combinatorial optimization problems that often arise in everyday life, especially in making decisions about selecting goods with limited capacity. This study combines two previous studies that apply genetic algorithms to real cases: the selection of basic necessities and packaged fruits in limited containers. Genetic algorithms are used because they are flexible and able to find more than one optimal solution. The process includes the formation of an initial population, fitness evaluation, selection (roulette wheel), crossover, and mutation. From the two case studies analyzed, it was found that genetic algorithms consistently produce increased fitness between generations and are able to maximize the value of goods without exceeding capacity or budget limits. This study strengthens the potential of genetic algorithms as an effective method in solving Knapsack Problems based on real needs.

Mathematical literacy in the Programme for International Student Assessment (PISA) emphasizes students’ ability to analyze, justify, and effectively communicate ideas, as well as to formulate, solve, and interpret mathematical problems across various forms and contexts. The PISA assessment focuses on real-life problems rather than solely on typical classroom-based questions. Based on cognitive development stages, elementary school students are generally in the concrete operational stage, which means they require tangible objects that can be perceived through the senses. Since mathematics learning tends to be abstract, students need support in the form of media and teaching aids to clarify concepts delivered by the teacher, making them easier to understand. Mathematics instruction is expected to provide an integrated, comprehensive, and holistic understanding of the material. This understanding not only fulfills the demands of mathematical content but also offers practical benefits to students. This aligns with the contextual learning approach, which emphasizes active student engagement throughout the learning process, enabling them to discover concepts independently and relate them to real-life situations. Contextual learning is carried out through four main stages: providing motivation, conceptual understanding, application, and assessment—all of which are grounded in the core components of contextual learning.
