Abstract

Perkembangan ekonomi global yang pesat telah menyebabkan peningkatan permintaan akan makanan, terutama di sektor kuliner. Warung makan Warmindo, salah satu bentuk Usaha Kecil dan Menengah (UKM) di bidang kuliner, menjadi pilihan yang populer di kalangan mahasiswa. Untuk bertahan dan berkembang di pasar yang kompetitif ini, warung makan Warmindo perlu beradaptasi dengan kemajuan teknologi. Aplikasi kasir sangat penting untuk manajemen keuangan yang efisien dan kepuasan pelanggan. Teknologi yang semakin maju memudahkan bisnis untuk bekerja dengan cepat dan efisien. Aplikasi kasir menawarkan fitur-fitur seperti penghitungan, pencatatan, dan laporan keuangan, sehingga meminimalisir kecurangan dan meningkatkan produktivitas karyawan. Selain itu, aplikasi absensi yang terintegrasi dapat membantu dalam pengolahan data dan pemantauan kehadiran, meningkatkan disiplin karyawan. Penelitian ini menerapkan aplikasi kasir dan sistem absensi terintegrasi pada Restoran WARMINDO NOCTURNAL di Semarang Barat, Kota Semarang, Jawa Tengah. Aplikasi ini bertujuan untuk mengoptimalkan proses penjualan dan transaksi, serta pemantauan kehadiran karyawan yang terintegrasi.

Abstract

Cataract is a leading cause of blindness worldwide, emphasizing the need for an effective early detection approach. This study evaluates the capabilities of three widely-used deep learning models—ResNet-50, EfficientNet-B1, and VGG-16—in classifying visual data. The analysis was conducted on a dataset of 2,112 images, comprising 1,074 normal cases and 1,038 cataract cases. The findings reveal that ResNet-50 achieved the best accuracy at 98.61%, followed by EfficientNet-B1 at 96.64% and VGG-16 at 93.82%. In comparison, previous research using Convolutional Neural Network (CNN) techniques reported an accuracy of 92.93%. These results highlight ResNet-50's superior potential for image classification tasks in this domain. This study contributes significantly to the selection of robust models for building an automated cataract detection framework.

Abstract

The skin, being the largest organ in the human body, plays a vital role in protecting against various external threats. However, cases of skin diseases are steadily rising across countries, making it a significant global health concern. Diagnosis often faces challenges due to symptom variations and low public awareness, highlighting the need for automated technology in skin disease detection. This study developed an automated classification system for skin diseases using EfficientNet-B1, capable of categorizing five skin conditions: Acne and Rosacea, Eczema, Melanoma Skin Cancer Nevi and Moles, Normal, Vitiligo, Psoriasis pictures Lichen Planus and related diseases, Seborrheic Keratoses and other Benign Tumors, Tinea Ringworm Candidiasis and other Fungal Infections. The system utilized 1.571 plus 1641 JPG digital images resized to 224 x 224 pixels, with 80% of the data allocated for training and 20% for testing. The trained model achieved a high accuracy of 99%, demonstrating the system's potential to support faster and more accurate diagnostic processes.
