Sistem dapat mengelola alat ukur, memproses kalibrasi internal, memproses kalibrasi eksternal, memberikan reminder, generate sertifikat kalibrasi, memproses peminjaman alat ukur dengan fitur scan kartu mahasiswa, dan mengelola laporan. Sistem ini dibangun menggunakan Laravel dan React. Database yang digunakan adalah mySQL. Pengujian pada pengguna menggunakan metode SUS memberikan skor baik yaitu 83,75. Pengguna juga menyetujui bahwa sistem ini membantu manajemen kalibrasi supaya terkelola secara efektif dan efisien. Kata Kunci: kalibrasi, manajemen, alat ukur, website Abstract. Recalibration of measuring instruments needs to be done regularly. Polytechnic XYZ always recalibrates each measuring instrument at least once a year. Currently, the calibration intervals on each measuring instrument are not well managed by the laboratory, which allows for errors in measurement results because recalibration is not carried out on time. Therefore, a calibration management system is needed to be able to manage calibration data and the use of each measuring instrument. This system is made based on a website. The system can manage measuring instruments, process internal calibrations, process external calibrations, provide reminders, generate calibration certificates, process measuring instrument loans with the student card scanning feature, and manage reports. This system is built using Laravel and React. The database used is MySQL. User testing using the SUS method gave a good score of 83.75. Users also agree that this system helps calibration management to be managed effectively and efficiently.Keyword: calibration, management, measuring instruments, website

Abstract

The social media platform X is often misused, one example being the creation of fake accounts operated by bots. To address this issue, various machine learning models have been developed to detect bot accounts, particularly Random Forest, XGBoost, and Support Vector Machine (SVM). This study aims to compare the performance of these three models in predicting bot accounts on social media platform X and to determine the best model based on the f1-score. In addition, this research applies three hyperparameter tuning methods, namely grid search, random search, and Bayesian optimization. The results show that the XGBoost model with Bayesian optimization achieves the best performance. However, its performance decreases when applied to imbalanced datasets.   Penggunaan media sosial X seringkali disalahgunakan, salah satunya dengan membuat akun palsu yang dijalankan oleh bot. Saat ini, telah banyak dikembangkan sistem untuk mendeteksi akun bot pada media sosial X dengan memanfaatkan model machine learning, khususnya algoritma Random Forest, XGBoost, dan SVM. Penelitian ini bertujuan untuk membandingkan performa dari ketiga model tersebut dalam memprediksi akun bot pada media sosial X dan menentukan model terbaik berdasarkan nilai f1-score. Pada penelitian ini juga dikembangkan penggunaan hyperparameter tuning grid search, random search, dan Bayesian optimization. Hasil penelitian ini menunjukkan bahwa model terbaik untuk prediksi akun bot pada media sosial X adalah XGBoost dengan hyperparameter tuning Bayesian optimization. Namun, model ini mengalami penurunan performa ketika digunakan untuk memprediksi akun bot pada data yang tidak seimbang.
