Abstract

This research aimed to analyzing student?s honest behavior grade VIIA and VIIB in SMP Negeri 6 Kota Jambi through integrated science learning in calor and its transfer. Data collection techniques are carried out by observation and documentation using questionnaire instruments. Data analysis in this research used descriptive statistical calculations. The result showed that student?s honest behavior grade VIIA in SMP Negeri 6 Kota Jambi through integrated science learning in calor and its transfer being in a good category, that is the percentage of 61,3%. While student?s honest behavior grade VIIB in SMP Negeri 6 Kota Jambi being in a very good category, that is the percentage of 60,0%. From all of result, it can be concluded that VIIA and VIIB grade student?s in SMP Negeri 6 Kota Jambi, have honest behavior in a very good category.

Abstract

This research discusses an analytical approach to suspension bridge accidents focusing on eigenvalue characteristics. This research uses eigenvalue analysis to explore patterns that may contribute to bridge structural failure. The analysis steps include reducing the model to an uncoupled and linear system, as well as determining homogeneous and non-homogeneous solutions, which helps identify accident-prone patterns. The analysis results also reveal significant differences in dynamic characteristics between safe bridges and those that experience accidents. This research highlights the importance of a deep understanding of eigenvalues in designing, maintaining, and managing suspension bridges. The implication of this research is the development of more effective prevention strategies to improve suspension bridge safety in the future. By analyzing eigenvalues, this research provides deep insight into the factors that influence the stability of suspension bridges. These findings provide a strong foundation for developing recommendations for more effective design, maintenance, and management of suspension bridges. The conclusions of this research can help improve the safety and reliability of suspension bridges worldwide and contribute to civil engineering and infrastructure security.

Abstract

The failure of the suspension bridge has been known since the beginning of the bridge collapse. Most of these failures form the basis of current engineering knowledge. One of the factors of failure is human-made factors related to the calculation of the bridge estimate. This paper presents an indirect estimation method using numerical simulation using finite elements by analyzing the Fokker-Planck model when dynamic excitation is associated with bridge loads. The results show that the Fokker-Planck model's homogeneous form can take into account the solution for the bridge analysis approach. It leads to a stable state when giving mass variations to the model. The indirect estimation method using finite elements can estimate the cable tension with controllable weak damping. It can be concluded that the method in this study is more accurate and convenient for the application technique.
