Abstract

ABSTRAKProduksi padi di Indonesia memiliki peran penting dalam menjaga ketahanan pangan nasional, namun produktivitasnya sering mengalami penurunan akibat serangan penyakit pada daun padi. Penyakit seperti blast, bercak coklat, dan hawar daun bakteri merupakan penyakit utama yang dapat menimbulkan kerugian signifikan jika tidak terdeteksi sejak dini. Identifikasi penyakit daun padi secara konvensional umumnya masih dilakukan secara manual dan bergantung pada pengalaman petani, sehingga berpotensi menimbulkan kesalahan diagnosis. Oleh karena itu, penelitian ini bertujuan mengembangkan sistem pendeteksi otomatis penyakit daun padi berbasis deep learning menggunakan algoritma YOLOv8. Dataset diperoleh dari pengambilan citra langsung di lahan pertanian Desa Jangan-Jangan, Kabupaten Barru, yang merepresentasikan kondisi lapangan nyata dan mencakup tiga jenis penyakit utama. Tahapan penelitian meliputi anotasi data menggunakan Roboflow, pelatihan model dengan Google Collab, serta evaluasi performa menggunakan confusion matrix, precision, recall, F1-score, dan mean Average Precision. Hasil pengujian menunjukkan bahwa model YOLOv8 mampu mendeteksi penyakit daun padi dengan akurasi tinggi dan waktu inferensi cepat, sehingga berpotensi diterapkan sebagai solusi deteksi dini penyakit padi secara real-time.

Diseases such as blast, brown spot, and bacterial leaf blight are major diseases that can cause significant losses if not detected early. Conventional rice leaf disease identification is generally still done manually and relies on farmer experience, potentially leading to misdiagnosis. Therefore, this study aims to develop an automatic rice leaf disease detection system based on deep learning using the YOLOv8 algorithm. The dataset was obtained from direct imagery captured in agricultural fields in Jangan-Jangan Village, Barru Regency, which represents real-world conditions and includes three main types of diseases. The research stages include data annotation using Roboflow, model training with Google Colab, and performance evaluation using a confusion matrix, precision, recall, F1-score, and mean Average precision. The test results show that the YOLOv8 model is capable of detecting rice leaf diseases with high accuracy and fast inference time, thus potentially being implemented as a real-time early detection solution for rice diseases.

Abstract

ABSTRAKManajemen ruang rawat inap merupakan komponen penting dalam operasional rumah sakit karena berkaitan langsung dengan kualitas pelayanan dan keselamatan pasien. Peningkatan jumlah pasien, keterbatasan kapasitas kamar, serta sistem penjadwalan yang masih bersifat manual sering menyebabkan ketidakefisienan dalam alokasi ruang rawat inap. Penelitian ini bertujuan untuk mengoptimalkan manajemen ruang rawat inap di RS PKU Unismuh Makassar melalui penerapan algoritma Priority Scheduling. Metode penelitian yang digunakan adalah pendekatan kuantitatif terapan dengan simulasi sistem berbasis data ketersediaan kamar, kondisi medis pasien, tingkat urgensi, kelas ruang rawat inap, serta spesialisasi dokter. Algoritma Priority Scheduling diterapkan untuk menentukan urutan pelayanan dan alokasi kamar berdasarkan prioritas medis pasien. Hasil penelitian menunjukkan bahwa sistem mampu mengalokasikan ruang rawat inap secara optimal, terutama bagi pasien dengan prioritas tinggi, dengan tingkat efisiensi penggunaan ruang mencapai 100%. Selain itu, sistem dapat mengurangi waktu tunggu dan meningkatkan ketepatan pengambilan keputusan dalam penempatan pasien. Kesimpulan dari penelitian ini menunjukkan bahwa algoritma Priority Scheduling efektif dan adil dalam mendukung optimalisasi pengelolaan ruang rawat inap. Implikasi penelitian ini diharapkan dapat menjadi dasar pengembangan decision support system berbasis algoritma dalam manajemen rumah sakit.

The increasing number of patients, limited room capacity, and manual scheduling systems often lead to inefficiencies in inpatient room allocation. This study aims to optimize inpatient room management at PKU Unismuh Makassar Hospital through the application of the Priority Scheduling algorithm. The research employs an applied quantitative approach using system simulation based on inpatient room availability data, patients’ medical conditions, urgency levels, room class categories, and doctors’ specializations. The Priority Scheduling algorithm is implemented to determine service order and room allocation according to patients’ medical priority levels. The results indicate that the proposed system is able to allocate inpatient rooms optimally, particularly for high-priority patients, achieving 100% room utilization efficiency for critical cases. In addition, the system reduces patient waiting time and improves the accuracy of decision-making in room assignment. The study concludes that the Priority Scheduling algorithm is an effective and fair approach for optimizing inpatient room management. The findings imply that this algorithm can be utilized as a decision-support system to enhance efficiency, responsiveness, and resource utilization in hospital inpatient services.

Abstract

ABSTRAKProgram Rujuk Balik (PRB) BPJS Kesehatan bertujuan menjamin keberlanjutan pengobatan pasien penyakit kronis. Namun, fluktuasi kebutuhan obat sering menimbulkan permasalahan overstock dan stockout di apotek mitra BPJS. Penelitian ini bertujuan mengintegrasikan analisis diferensial dan algoritma deep learning Long Short-Term Memory (LSTM) untuk meningkatkan akurasi prediksi kebutuhan obat PRB. Data yang digunakan berupa transaksi penjualan obat pasien BPJS PRB di Apotek Kimia Farma Cendrawasih periode Januari 2022 hingga Juli 2024. Analisis diferensial digunakan untuk menghitung perubahan tingkat pertama (delta 1) dan tingkat kedua (delta 2) penjualan, yang selanjutnya dijadikan fitur tambahan pada model LSTM. Evaluasi model dilakukan menggunakan metrik Mean Squared Error (MSE), Mean Absolute Error (MAE), dan Mean Absolute Percentage Error (MAPE). Hasil penelitian menunjukkan bahwa integrasi analisis diferensial dengan LSTM mampu meningkatkan akurasi prediksi, dengan model terbaik menghasilkan nilai MAE rata-rata di bawah 20 untuk sebagian besar produk. Temuan ini berimplikasi pada peningkatan efektivitas perencanaan dan pengadaan obat PRB berbasis data historis dan tren perubahan.Kata Kunci: Prediksi Obat, BPJS PRB, LSTM, Deep Learning, Analisis Diferensial ABSTRACTThe BPJS Kesehatan Rujuk Balik Program (PRB) aims to ensure the continuity of treatment for patients with chronic diseases. However, fluctuations in medicine demand frequently cause overstock and stockout problems at BPJS partner pharmacies. This study aims to integrate differential analysis and the Long Short-Term Memory (LSTM) deep learning algorithm to improve the accuracy of PRB medicine demand forecasting. The data used consist of transaction records of PRB patient medicine sales at Kimia Farma Cendrawasih Pharmacy from January 2022 to July 2024. Differential analysis was applied to calculate the first-order change (delta 1) and second-order change (delta 2) in sales, which were subsequently incorporated as additional features in the LSTM model. Model performance was evaluated using Mean Squared Error (MSE), Mean Absolute Error (MAE), and Mean Absolute Percentage Error (MAPE). The results indicate that integrating differential analysis with LSTM improves prediction accuracy, with the best-performing model achieving average MAE values below 20 for most products. These findings have important implications for enhancing data-driven planning and procurement of PRB medicines based on historical trends and demand dynamics.Keyworsds: Medicine Forecasting, BPJS PRB, LSTM, Deep Learning, Differential Analysis
