Abstract

Pada perkembangan teknologi saat ini membawa banyak dampak perubahan signifikan bagi kehidupan anak-anak hingga orang dewasa, salah satu yang paling menarik perhatian penulis ialah perubahan pola belajar anak-anak yang di pengaruhi oleh perkembangan teknologi. Dimana anak-anak lebih sering menatap layar smartphone dari pada membaca buku pelajaran, sehingga minat membaca di kalangan anak-anak remaja sangat menurun. Bahkan anak remaja saat ini hampir kebanyakan belum mengetahui pembelajaran komponen jaringan. Oleh sebab itu saya sebagai penulis cukup prihatin dengan perkembangan pola belajar anak remaja dikalangan sekolah pada saat ini yang di sebabkan oleh perkembangan tekonologi. Berdasarkan masalah yang telah diungkapkan diatas, terlihat bahwa sistem pembelajaran pendidikan pada saat ini dapat di tingkatkan guna mendapatkan pola pembelajaran yang lebih baik lagi. Dimana hampir seluruh anak-anak pada tingkat Sekolah SMK Teladan Medan sudah memiliki smartphone sendiri, sangat dimungkinkan untuk mengembangkan teknologi dalam sistem pembelajaran yang dapat menyelesaikan masalah-masalah yang telah diungkapkan diatas. Oleh sebab itu dalam penulisan skripsi penulis akan membuat sebuah media pembelajaran tentang pembelajaran komponen jaringan berbasis android agar lebih menarik dan meningkatkan minat belajar anak remaja khususnya pelajar. Pada aplikasi yang akan penulis buat kali ini bertujuan untuk mempermudah anak sekolah SMK Teladan Medan dalam mengenal dan mempelajari perangkat keras komponen jaringan computer di SMK Teladan Medan. Aplikasi pembelajaran komponen jaringan ini di buat menggunakan software Unity 3D, serta pembuatan model pola komponen jaringan penulis menggunakan software Blender. Untuk model pola komponen jaringan yang di hasilkan pada aplikasi ini berupa gambar hewan 3 Dimensi (3D) yang apabila pengguna mengarahkan kamera pada objek atau gambar 3D maka pada aplikasi akan muncul gambar 3 Dimensi (3D) berbentuk pola komponen jaringan yang telah di tangkap oleh kamera pengguna.

Abstract

SMP Negeri 2 is one of the State Junior High Schools located in Hamparan Perak District, Deli Serdang Regency, North Sumatra Province. This school has approximately 20 teaching teachers. The school is located at Jalan Pasar 2, Tandam Hilir II Village, Hamparan Perak District, Deli Serdang Regency, North Sumatra Province. Because it is a little far from the city, the development of technology in terms of teaching is still little known. Merdeka Learning is a policy program from the Ministry of Education and Culture of the Republic of Indonesia (Kemendikbud RI) which was launched by the Minister of Education and Culture of the Republic of Indonesia for the Advanced Indonesia Cabinet, Nadiem Anwar Makarim. The essence of freedom of thought, according to Nadiem, must be preceded by teachers before they teach it to students. Nadiem said, in the competence of teachers at any level, without a translation process of the basic competencies and existing curriculum, there will never be any learning that takes place. For this reason, the institution forms a team that will provide material on making moving animations for training at the school. The author as one of the presenter team uses power point slides in the form of presentations, direct practice of accessing the independent learning web application using each teacher's account. From before, the understanding to access and use the independent learning modules for approximately 20 teachers who attended the training was only 10%, but after attending the training it increased to 80%. Understanding is obtained by doing upload module tests, create classes, create quizzes and exams, and also absent students to teachers after being given the training. The training carried out by the Main Potential University Institution team is also an embodiment of the Lecturer's Tri Dharma, namely Community Service.

Abstract

Kegiatan pengabdian masyarakat ini bertujuan meningkatkan motivasi mengajar guru Madrasah Tsanawiyah yang selama ini masih rendah akibat keterbatasan pemahaman pembelajaran mendalam dan dominasi metode konvensional. Program dilaksanakan di MTs Al-Fauzi dengan melibatkan 20 guru melalui workshop inovatif berbasis praktik langsung, diskusi kolaboratif, dan simulasi perangkat ajar. Hasil awal menunjukkan motivasi guru didominasi kategori sedang (45%) dan rendah (35%), sementara hanya 20% yang tinggi. Setelah pelatihan, distribusi berubah signifikan: motivasi rendah menurun menjadi 10%, sedang 30%, dan tinggi meningkat hingga 60%. Pergeseran ini menegaskan bahwa pelatihan inovatif efektif dalam memperkuat motivasi guru untuk mencoba strategi baru, meningkatkan keterlibatan siswa, dan membangun suasana kelas yang lebih aktif. Dengan demikian, kegiatan ini berkontribusi nyata terhadap penguatan motivasi profesional guru sekaligus mendukung implementasi Kurikulum Merdeka.

Abstract

Ulasan pengguna terhadap layanan Goride di Google Playstore merupakan sumber data krusial untuk evaluasi kualitas layanan, namun analisis manual terhadap volume data besar tidak efisien. Penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem klasifikasi sentimen otomatis menggunakan metode Support Vector Machine (SVM) untuk mengkategorikan ulasan pengguna Goride menjadi sentimen positif atau negatif. Sebanyak 659 ulasan dari periode Januari Desember 2024 dianalisis melalui serangkaian tahapan pra-pemrosesan data, pelabelan data, dan ekstraksi fitur menggunakan Term Frequency-Inverse Document Frequency (TF-IDF). Model SVM dioptimalkan menggunakan GridSearchCV mencapai performa puncak dengan akurasi 87,88%, presisi 66,67%, recall 85,71%, dan F1-Score 75,00% pada konfigurasi terbaik (C=0.1, kernel linear). Hasil ini mengonfirmasi bahwa SVM merupakan metode yang efektif dan tangguh untuk analisis sentimen pada ulasan layanan transportasi daring, serta menyediakan alat praktis yang berpotensi mendukung pengambilan keputusan strategis berbasis data untuk peningkatan layanan Gojek.
