Abstract

Wireless multimedia sensor networks (WMSNs) have characteristics that may influence the routing decisions, such as limited energy resources, storage and computing capacity. Therefore, a routing optimization needs to be done to match the characteristics of the WMSNs. Existing routing protocols only consider energy efficiency regardless of energy threshold, maximum energy, and link cost collectively as the primary basis of routing. In this work, the energy-efficient dynamic programming (EEDP) protocol is proposed to optimize routing decisions that take into account the energy threshold, the maximum energy, and the link cost. Then, the protocol is compared with the dynamic programming (DP), and the ant colony optimization (ACO) protocol. The simulation results show that the EEDP protocol can improve energy efficiency of nodes and network lifetime of the WMSNs. Then, the EEDP protocol is also implemented into a network topology of 10 NodeMCU ESP32 devices. As a result, the EEDP protocol can work very well by selecting routes based on nodes that have the remaining energy above 50 and has the shortest distance. The average delay in sending data for the entire route for the 10 iterations of sending data is 3.99 seconds.

Abstract

The thyroid gland plays a very important role in hormonal regulation in the human body. If the thyroid gland has a disorder, it can affect the performance of body functions. The development of artificial intelligence technology today allows an expert such as a doctor to be helped by his work. One of the important roles of artificial intelligence is helping doctors, among others, to diagnose a patient to determine appropriate post-diagnosis care. The study aims to shed light on the role of artificial intelligence in the treatment of thyroid disorders.The thyroid gland plays a very important role in hormonal regulation in the human body.

Abstract

The rapid growth of e-commerce in Indonesia, with a record 88.1% growth rate, has been accompanied by a surge in online fraud, leading to an estimated loss of 4.62 trillion rupiahs. Current fraud prevention methods, such as the widely used 3D-Secure system, though effective, result in a high rate of transaction abandonment (approximately 16%), which is undesirable for merchants. To address this, we propose an AI-based fraud detection system that leverages machine learning models to identify potentially fraudulent transactions. By employing a combination of classification algorithms, including logistic regression and neural networks, security protocols are activated only for high-risk transactions, optimizing transaction processing efficiency and improving detection accuracy. Our study focuses on fine-tuning key parameters of the AI-Fraud Detector model, specifically some parameters such as ∆ttrain, ∆tlag and f rac hr pass, to enhance detection performance over time. Simulation performances using ROCAUC, false positive rate (fpr), and true positive rate (tpr) metrics show that a configuration with a training period (∆ttrain) of 180 days, a lag period (∆tlag ) of 90 days, and a high-risk pass fraction (f rac hr pass) of 10% yields a balance between detection efficiency (∼ 50%) and a reduced false positive rate. It means that the model is able to identify approximately 50% of the actual high-risk events while minimizing the number of times it incorrectly identifies a low-risk event as high-risk. However, further research is required to refine these results, explore parameter optimization strategies, and enhance the model’s adaptability to evolving fraud patterns. Future work will focus on optimizing thresholds, improving model robustness over time, and ensuring effective detection of new fraud schemes. This research improves model performance by optimizing key parameters and enhancing detection accuracy while minimizing false positives

Abstract

Peran sistem pakar dapat membantu seorang ahli memecahkan masalah di bidang tertentu. Salah satu manfaat dari sistem ahli adalah bahwa ia digunakan untuk mendiagnosis penyakit tertentu atau gejala suatu penyakit. Faktor kepastian (certainty factor) memiliki aturan penting untuk sistem pakar dengan spesialisasi ini. Penyakit tiroid dikorelasikan dengan gangguan psikologis. Dewasa ini, banyak masyarakat masih memanfaatkan tumbuhan sebagai obat-obatan tradisional, dalam kajian ilmu biologi disebut sebagai etnobiologi. Beberapa pengobatan tanaman tradisional untuk penyakit tiroid juga digunakan masyarakat. Namun, belum ditemukannya sistem pakar untuk mendiagnosis penyakit tiroid dengan gejala-gejala psikologis beserta saran tanaman obatnya. Studi ini bertujuan menerapkan sistem pakar untuk mendiagnosis penyakit tiroid dengan gejala psikologis dan saran pengobatan tradisionalnya. Penelitian ini juga mengusulkan aplikasi sistem pakar berbasis Android yang dapat diimplementasikan bagi dokter. Metode penelitian menggunakan metode faktor kepastian dengan inferensi persentase tingkat kepercayaan dan saran tanaman obat tradisional yang bisa digunakan. Pengumpulan data melalui wawancara dokter dan studi literatur relevan untuk data etnobotani. Validasi sistem dilakukan oleh dokter dan ahli botani. Hasilnya adalah sistem pakar ini mampu memberikan validitas di atas 90% untuk penyakit tiroid dan dapat digunakan dokter untuk membantu mendiagnosis pasien dengan indikasi penyakit tiroid beserta gejala-gejala psikologisnya. AbstractThe role of an expert system can help an expert solve problems in a particular field. One of the benefits of the expert system is that it is used to diagnose a specific disease or symptom of a disease. The certainty factor has important rules for the system of experts with this specialty. Thyroid disease is correlated with psychological disorders. Nowadays, many people still use plants as traditional medicines, in the study of biological sciences it is referred to as ethnobiology. Some folk plant treatments for thyroid disease are also used by the public. However, there has not been a finding of an expert system for diagnosing thyroid disease with psychological symptoms along with suggestions for medicinal plants. The study aims to apply an expert system for diagnosing thyroid disease with its psychological symptoms and traditional treatment advice. This study also proposes an Android-based expert system application that can be implemented for doctors. The research method uses the method of certainty factor with inference of the percentage of the level of trust and suggestions of traditional medicinal plants that can be used. Data collection through physician interviews and literature studies is relevant for ethnobotanical data. Validation of the system is carried out by doctors and botanists. The result is that this expert system is able to provide validity above 90% for thyroid disease and can be used by doctors to help diagnose patients with indications of thyroid disease and their psychological symptoms.
