Abstract

Kemampuan siswa untuk menganalisis, menalar, serta merumuskan, memecahkan, dan menginterpretasikan masalah matematika dalam berbagai bentuk dan konteks merupakan inti keterampilan matematika. didalam  mengajarkan matematika di Sekolah Menengah Pertama hal yang tidak mudah, bahkan rintangannya sangat banyak sekali dan kendala yang dialami oleh para pendidik. terkhusus pembelajaran yang dapat mendukung keterampilan numerasi, dan memiliki manfaat secara kontekstual dalam memecahkan masalah didalam kehidupan. untuk mengevaluasi dampak dari model pembelajaran berbasis masalah akan kecakapan matematika dan numerik siswa kelas VII di SMP Muhammadiyah 51 Sidikalang merupakan tujuan dari penelitian ini. Penelitian ini memakai metode eksperimen semu serta metode survei kuantitatif dan desain pre-test dan post-test group. dengan mengikutsertakan statistik deskriptif dan statistik analisis inferensial merupakan bagian dari analisis dalam penelitian ini. analisis data awal memakai statistik deskriptif menunjukkan bahwa sebelum diterapkannya model pembelajaran berbasis masalah di SMP Swasta Muhammadiyah 51 Sidikalang, kinerja siswa dalam kategori rendah sebesar 24% dan kategori sedang atau tercapai sebesar 76%. Namun, setelah penerapan model pembelajaran berbasis masalah, terjadi peningkatan signifikan dalam kinerja siswa. Proporsi siswa dalam kategori sedang meningkat sebesar 20%, sementara proporsi siswa dalam kategori tinggi meningkat sebesar 80%. hasil dari analisis statistik inferensial menggunakan paired sample T-test terlihat kalau nilai signifikansi lebih besar dari 0,05. Hal ini mengindikasikan jika penerapan model pembelajaran berbasis masalah berdampak positif terhadap kemampuan matematika dan numerik siswa setelah dilakukan pengujian statistik. Dengan demikian, dapat ditarik kesimpulkan kalau pengaruh model pembelajaran berbasis masalah di SMP Swasta Muhammadiyah 51 Sidikalang Kelas VII memiliki dampak yang positif terhadap keterampilan matematika dan numerik siswa.

Abstract

In the natural language processing field, there are several sub-fields that are very closely related to information retrieval, such as the automatic text summarization sub-field. obtained from the convolutional T5 and Seq2Seq models in summarizing text on hugging faces found features that can affect text summary such as upper- and lower-case letters which have an impact on changing the understanding of the text of the document. This study uses a combination of parameters such as layer dimensions, learning rate, batch size, and the use of Dropout to avoid model overfitting. The results can be seen by evaluating metrics using ROUGE. This study produces a value of ROUGE-1 on 4 documents that are tested which produces an average of 0.8 which is the optimal value, for ROUGE-2 on 4 documents that are tested which results in an average of 0.83 which is an optimal value while ROUGE-L on 4 documents conducted tests that produce an average of 0.8 which is the optimal value for the summary model.

Abstract

The low motivation of students to learn resulted in low KKM scores achieved. Field facts show that many students have not achieved the set KKM scores. Therefore, the use of demonstration methods is considered as a solution to increase student learning motivation, especially in mathematics subjects at SMA Negeri 1 Stabat.This study uses classroom action research methods. The observation results showed an increase from cycle I to cycle II, reaching the high category between 65% to 84%. In cycle I, student motivation was 65.52%, increasing to 86.25% in cycle II, in a very high score range. There was an increase in student learning motivation by 20.73% from cycle I to cycle II.In conclusion, the application of demonstration methods is effective in increasing student learning motivation, both individually and classically. This is evident from the increase in the percentage of student learning motivation from 65.52% (cycle I) to 86.25% (cycle II), which is in the very high score range. Thus, it can be concluded that the demonstration method is effective in increasing students' motivation to learn mathematics.

Abstract

Penelitian ini bertujuan untuk merancang dan mengimplementasikan aplikasi absensi karyawan berbasis Face Recognition pada Universitas Harapan Medan. Latar belakang penelitian ini adalah kurangnya efektivitas sistem absensi yang saat ini digunakan, yaitu menggunakan aplikasi WhatsApp dengan foto wajah dan nama pegawai. Dalam kondisi bekerja dari rumah selama pandemi Covid-19, sistem absensi tersebut tidak akurat dan efektif. Oleh karena itu, penggunaan absensi berbasis identifikasi wajah atau Face Recognition diusulkan. Metode kerja penelitian ini mencakup tahapan persiapan bahan dan alat, pelaksanaan prosedur penelitian, analisis sistem absensi berbasis Face Recognition, serta pengumpulan data primer dan sekunder. Hasil penelitian ini meliputi perancangan sistem absensi berbasis Face Recognition menggunakan UML dengan Use Case Diagram, Class Diagram, dan Activity Diagram. Selain itu, dirancang juga antarmuka pengguna berupa halaman web yang meliputi halaman login, dashboard admin, data karyawan, data departemen, data kehadiran, laporan, setting, dashboard user, dan halaman absensi. Metode pengembangan perangkat lunak yang digunakan adalah System Development Life Cycle (SDLC), dengan tahapan perencanaan, analisis, perancangan, implementasi, dan pengujian. Setelah implementasi sistem, dilakukan pengujian untuk memastikan bahwa semua kebutuhan fungsional terpenuhi. Berdasarkan hasil penelitian dan pengujian sistem, dapat disimpulkan bahwa aplikasi absensi berbasis Face Recognition ini dapat meningkatkan efektivitas dan akurasi proses absensi karyawan di Universitas Harapan Medan.
