Abstract

Padi adalah tanaman pangan utama di Indonesia dan memiliki peran vital dalam perekonomian serta kehidupan sehari-hari masyarakat. Namun, produksi padi saat ini mengalami penurunan akibat serangan hama dan penyakit. Deteksi dini dan klasifikasi penyakit padi yang akurat sangat penting untuk mengurangi dampak negatif ini. Penelitian ini membangun dan melatih model Convolutional Neural Network (CNN) menggunakan arsitektur MobileNetV3 Large untuk mengenali kondisi kesehatan tanaman padi. Model dilatih dengan dataset citra daun padi berlabel, melalui 30 epoch, batch size 45, dan optimizer Lion. Hasil pengujian menunjukkan akurasi 75% untuk data uji dengan loss 59%, dan akurasi 76% untuk data latih dengan loss 61%. Model ini juga berhasil diimplementasikan dalam aplikasi mobile berbasis Android. Penelitian ini diharapkan dapat berkontribusi pada sektor pertanian Indonesia dengan menyediakan alat deteksi penyakit padi yang lebih efisien dan efektif.

Abstract

PT. Indo-Rama Synthetics Tbk is a company that manufactures Polyester Filament Yarns, “Polyester Stapel Fibers Pet Resin:, Polyester Chips and Polyester Filament Fabrics, where the company started commercial production in 1976 with a cotton spinning factory in Purwakarta which has around ± 1000 employees with various departments and positions. However, the leave application system is still manual. Where employees must make a written leave application and follow several processes that must be carried out. The design and development of the employee leave system uses the rapid application development software development method with stages (requirements planning, user design, construction and cutover), the design uses a unified modeling language (UML) with 4 (four) diagrams, namely use case diagrams, activity diagrams, sequence diagrams and class diagrams, program coding using the PHP framework Codeigniter. The results achieved from this study are an employee leave system for employees by providing several existing features including employee information, submission of leave for employees, and other menus. With the web and mobile based system,  it is hoped that it will make it easier for employees to apply for leave.
