Abstract

Absensi dapat dikatakan suatu tanda kehadiran yang merupakan bagian dari aktifitas pelaporan yang ada dalam sebuah institusi. Tidak terkecuali pada sistem absensi sekolah untuk menandaai kehadiran siswa umumnya masih dilakukan secara manual, dimana hal ini sangat tidak efisien karena informasi tentang kehadiran bisa saja terjadi kecurangan baik dari pihak murid ataupun guru yang salah dalam menandai kehadiran siswa. Oleh sebab itu sangat perlu untuk diterapkan sebuah teknologi yang dapat membantu proses absensi di sekolah. Sehingga dapat meningkatkan kualitas sistem pada layanan kehadiran siswa. Dalam pelaksanaan PKM ini akan dirancang sebuah sistem absensi yang dapat dibangun dan diatur sistem informasi kehadiran. Kehadiran dicatat dengan memindai kartu ID siswa Anda dengan pembaca kode QR. Setiap siswa menerima kartu yang dapat dicetak dari sistem menggunakan kode QR yang unik. Kode ini akan diterjemahkan ke dalam sistem saat siswa akan hadir/keluar dari sekolah. Dengan sistem informasi ini, maka data kehadiran siswa dapat tercatat dan terekapitulasi dengan cepat bila dibandingkan dengan metode manual.

Abstract

Pengembangan Game sangat berbeda dengan pengembangan aplikasi komputer yang hanya membutuhkan algoritma, bisnis proses dan basis data. Game membutuhkan aset multimedia berupa gambar, animasi, audio, dan pemrograman yang berbasis thread. Pengembangan game dan pengembangan perangkat lunak merupakan dua bidang yang berbeda meskipun keduanya berfokus pada pengembangan aplikasi komputer. Pelatihan pembuatan game berbasis UNITY di SMK PAB 2 Helvetia Medan bertujuan untuk meningkatkan kompetensi guru dalam teknologi pengembangan game. Workshop ini diadakan pada tanggal 28 September 2024 dan bertujuan agar para guru dapat mengajarkan siswa untuk membuat game berbasis 2D dan 3D. Pelatihan ini memfokuskan pada penguasaan dasar-dasar UNITY, mulai dari antarmuka pengguna, pembuatan objek, hingga pemrograman interaksi game. Kegiatan ini diakhiri dengan evaluasi melalui hasil karya siswa yang dihasilkan setelah guru mengimplementasikan materi yang telah diajarkan. Pelatihan ini menunjukkan hasil positif dalam mengembangkan keterampilan guru, serta meningkatkan motivasi belajar siswa melalui media pembelajaran berbasis game.

Abstract

Preprocessing data is needed some methods to get better results. This research is intended to process employee dataset as preprocessing input. Furthermore, model decision algorithm is used, random tree and random forest. Decision trees are used to create a model of the rule selected in the decision process. With the results of the preprocessing approach and the model rules obtained, can be a reference for decision makers to decide which variables should be considered to support employee performance improvement

Abstract

Breast cancer is a significant disease impacting women globally, highlighting the necessity for precise and dependable diagnostic models. This study aims to improve breast cancer prediction by optimizing the Random Forest algorithm using Ant Colony Optimization (ACO). This study uses datasets containing various cell characteristics to build and evaluate models. The ACO algorithm is applied to fine-tune the hyperparameters of the Random Forest model and improve its predictive performance. The experimental results showed that the optimized Random Forest model outperformed the baseline model in all evaluation metrics. The optimized model achieved an accuracy of 94.74%, precision of 97.92%, recall 90.38%, an F1 score of 92.93%, and an AUC score of 0, 9449 compared to the basic Random Forest model, with lower scores across all metrics. This improvement highlights the effectiveness of ACOs in improving model performance, especially in reducing false negatives, which are critical for medical diagnosis. This study demonstrates that ACO successfully fine-tunes Random Forest hyperparameters, achieving superior accuracy compared to baseline and outperforming previous optimization methods such as PSO. These findings confirm that the combination of Random Forest and ACO offers a powerful and effective approach to improving the accuracy of breast cancer predictions, making them a valuable tool for clinical decision-making.
