Abstract

Deteksi nominal uang Rupiah yang cepat dan akurat sangat penting untuk menjaga integritas transaksi ekonomi. Penelitian ini mengembangkan sistem sederhana untuk mendeteksi nominal uang Rupiah menggunakan algoritma YOLOv8. Algoritma YOLOv8 dipilih karena keunggulannya dalam deteksi objek secara real-time dengan akurasi tinggi dan efisiensi komputasi yang baik. Dalam penelitian ini, dataset gambar uang Rupiah asli digunakan untuk pelatihan model menggunakan Google Colab dan OpenCV. Hasil eksperimen menunjukkan bahwa algoritma YOLOv8 berhasil mendeteksi nominal uang Rupiah dengan tingkat akurasi yang tinggi. Implementasi algoritma ini diharapkan dapat memberikan solusi praktis bagi masyarakat dalam mengidentifikasi nominal uang Rupiah dengan cepat dan efektif, serta membantu mengurangi kesalahan dalam transaksi keuangan.

Abstract

The aim of this research is to design a basic food sales information system at CV. Java-based Ferdi to assist employee performance in processing purchasing and sales data. This system is designed to increase the efficiency and effectiveness of store operations by utilizing information technology. Researchers conducted field studies to understand the shop's business processes in depth, starting from collecting data on goods, ordering to suppliers, to the sales process to customers. Apart from that, researchers also conducted interviews with employees and shop owners to identify system needs. Based on the results of the needs analysis, the researcher designed a system database in the form of interconnected tables to support system functions. The system is designed using the Java programming language with the waterfall method to facilitate system development and maintenance in the future. The main function of the system includes inputting master data such as goods, suppliers and employee data. There is also a module for carrying out sales transactions and ordering goods from suppliers online. Apart from that, there are reports that can be generated by the system such as sales reports, stock of goods, and financial reports for easy business analysis by shop owners. Test results show the system is able to meet business needs and can increase employee productivity.

Abstract

Sugarcane is one of the most widely cultivated plantation crops in Indonesia, but production has declined, particularly in Kapanewon Sedayu, Bantul, due to a suspected nitrogen deficiency. Nitrogen is required for the formation of buds, leaves, and stems. GNDVI is a vegetation index that is more sensitive to chlorophyll content. This study aims to determine the correlation between GNDVI and the nitrogen content of sugarcane tissue based on drone imagery, to develop an estimation model, and to produce an N-content map. The research was conducted at the Gunung Ombo Plantation, Argomulyo, Sedayu, Bantul, Yogyakarta, using a quantitative descriptive method. Forty-five sample points were established (30 for prediction and 15 for reference). Leaf samples were collected from the third leaf sheath of 5-month-old sugarcane and analyzed for nitrogen content using the Kjeldahl method. The relationship between GNDVI and tissue nitrogen was examined using Pearson’s correlation, linear regression, and paired t-tests. Results showed a strong correlation (r = 0.896) with a coefficient of determination (R² = 0.7891) and the regression equation y = 4.7507x + 0.6012. The paired t-test indicated no significant difference between predicted and reference nitrogen values. The resulting estimation map can support nitrogen fertilization management in sugarcane cultivation in the study area.
