Abstract

Graph of real valued continuous function with special addition and multiplication has already proven that is isomorphic to real number system. Furthermore, the graph of continous real valued function forms a field. The aim of this research was to generalize such concept to its n-tuple Cartesian Product and to prove that interchange of basis still able to be executed. The result of this research is n-tuple Cartesian Product of graph function forms a vector space over  and interchange of basis still able to be executed

Abstract

Many indexes are involved on ordinary power series calculation. One of the most valuable discovery on previous research is Ops Transformation which able to simplify notations of ordinary power series to avoid some more complicated manipulations. The aim of this research is to generalize the concept of Ops Transformation to gain more benefit and wider applications. The main result of this research is a new formula of generalization of Ops Transformation which called C-Type Ops Transformation. Such transformation is able to solve some differential equations which involving Taylor series

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.

Abstract

Keterbatasan pembelajaran yang hanya berfokus pada mendengarkan, mengerjakan tugas, dan terpaku pada buku saja, mengakibatkan minimnya interaksi antara guru dan siswa serta antar siswa sendiri, sehingga menyebabkan pembelajaran menjadi tidak efektif dan berdampak pada rendahnya hasil belajar siswa. Penelitian ini dilakukan dengan tujuan meningkatkan hasil belajar peserta didik dalam Mata Pelajaran Matematika, terutama materi Pengurangan, di kelas I A SD Muhammadiyah 3 Surakarta dengan menerapkan Model Pembelajaran Problem Based Learning (PBL). Metode penelitian ini adalah penelitian tindakan kelas yang dilakukan dalam dua siklus serta satu pra siklus, dengan pengumpulan data menggunakan tes untuk hasil belajar yang kemudian dianalisis dengan analisis data deskriptif. Hasil penelitian menunjukkan adanya peningkatan signifikan dalam hasil belajar peserta didik setelah penerapan PBL. Pada pra siklus, rata-rata hasil belajar adalah 52,8, dengan nilai Kriteria Ketercapaian Tujuan Pembelajaran (KKTP) secara klasikal sebesar 16%. Namun, pada Siklus I, rata-rata hasil belajar meningkat menjadi 74,4 dengan pencapaian KKTM secara klasikal sebesar 56%. Kemudian, pada Siklus II, terjadi peningkatan lebih lanjut dengan rata-rata hasil belajar mencapai 88,4 dan pencapaian KKTM secara klasikal mencapai 88%. Hasil ini menunjukkan bahwa penerapan model pembelajaran PBL berhasil meningkatkan hasil belajar peserta didik kelas I A pada materi pengurangan. Sehingga dapat disimpulkan bahwa model pembelajaran PBL efektif dalam meningkatkan interaksi antara guru dan siswa serta antar siswa sendiri, yang pada gilirannya meningkatkan efektivitas pembelajaran dan hasil belajar siswa.

Abstract

Anak berkebutuhan khusus (ABK) adalah anak yang memerlukan penanganan khusus karena adanya gangguan perkembangan dan kelainan yang dialami anak. Sekolah Luar Biasa (SLB) BC Paramitha Graha Banjarmasin merupakan sekolah yang berfokus kepada anak berkebutuhan khusus. Sekolah ini memiliki 2 kategori ketunaan, yang dimana kategori tersebut adalah kategori B atau Tunarungu dan kategori C atau Tunagrahita. Dalam proses pembelajaran di SLB sistem pembelajarannya menggunakan metode konvensional seperti belajar dikelas dengan tambahan alat bantu yang sesuai dengan kebutuhannya dan dengan didampingi guru. Namun dalam proses belajar tersebut kadang terlewatkan oleh para orang tua yang mana anak berkebutuhan khusus membutuhkan pendampingan langsung oleh orang tua sendiri. Sistem e-learning penunjang pembelajaran anak berkebutuhan khusus ini akan dikelola oleh masing-masing guru berkebutuhan khusus, guru dapat memberikan materi yang dapat diunduh untuk orang tua maupun anak berkebutuhan khusus itu sendiri. Guru juga dapat memantau dan memberikan penilaian langsung setelah diberikan tes atau ujian secara online dan dapat memberikan masukan kepada para orang tua. Pengujian ilmiah pada penelitian ini menggunakan metode MOS guna mengetahui kualitas sistem yang telah dirancang. Dari hasil pengujian didapat nilai sebesar 4,58 skala 5, sehingga dapat disimpulkan bahwa sistem yang dibangun sudah cukup baik dan sudah dapat berjalan sesuai dengan apa yang diharapkan
