Abstract

Penggunaan Alat Pelindung Diri (APD) merupakan salah satu aspek penting untuk menjaga keselamatan pekerja di lingkungan kerja. Namun, masih banyak pekerja yang mungkin lupa atau sengaja tidak menggunakan kelengkapan APD ini dengan beberapa faktor, seperti, kepala terasa berat dan ketat dengan penggunaan helm, atau merasa panas ketika menggunakan rompi pelindung. Hal ini tentunya dapat menimbulkan risiko bahaya ketika sedang bekerja. Oleh karena itu, penelitian ini bertujuan untuk merancang sebuah sistem yang dapat memantau penggunaan APD pada pekerja. Sistem ini menerapkan algoritma YOLOv5 dalam proses pendeteksian kelengkapan APD pekerja tersebut. Dengan menggunakan bobot model yang dihasilkan pada proses training dengan Image Size 640, Epoch 300, Batch size 8, maka pengujian pendeteksian APD pada tangkapan kamera pengintai CCTV perusahaan, menghasilkan nilai akurasi tertinggi 81% (person/pekerja), 87% (helm), 78% (rompi pelindung), 71% (tanpa rompi) dan 77% (tanpa helm). Berdasarkan nilai akurasi yang dihasilkan, maka dapat disimpulkan bahwa algoritma YOLOv5 ini mampu mendeteksi objek apapun dengan baik. Sistem yang dihasilkan dapat membantu supervisor dalam memantau penggunaan APD oleh pekerja sehingga risiko bahaya dapat dihindari sedini mungkin.

Abstract

Mastering mathematical formulas is often a challenge for high school students, especially grade XI students who cover complex topics such as algebra, trigonometry, calculus, and matrices. To help students understand and apply these formulas, an Android-based application was designed that provides interactive, easily accessible, and efficient learning facilities. Technological advances allow tasks to be completed more easily and in a shorter time, but increasingly sophisticated AI can still make mistakes in language translation, for example in chatgpt, the author's concern is that if there is an error in making mathematical formulas in completing the grade XI assignment, it will mislead students if they do not pay close attention and lack knowledge in completing the assignment. This study uses a descriptive method, which aims to describe or analyze the results without making broader generalizations. Application development follows the Prototype method, a widely used software development approach that allows for continuous interaction between developers and users, ensuring a clear understanding of system requirements and functionality. The results of the study include software testing using whitebox testing, which focuses on the internal structure and implementation of the application code. At this stage, the tester has complete knowledge of the system architecture and code. In addition, black-box testing is used for functional testing, where the behavior of a system is assessed by analyzing inputs and outputs. In black-box testing, the application is run, and data is entered to verify whether the output matches the expected results. This combination of testing methods ensures the robustness and functionality of the application in supporting 11th grade students with mathematical formulas.
