Abstract

Wireless Body Area Network (WBAN) consists of a number of sensor nodes that are attached to the human body, and intended for monitor the human body condition. The WBAN system has several wireless communication modules that are used for sending or exchanging data between sensor nodes and gateway nodes or gateway nodes. There are some factors that are used to decide which communication modules should be implemented on WBAN system, including communication efficiency, distance range, power consumption, and the effect of mobility on QoS. In this study, we analyze the impact of the kinematic movement of sensor nodes on QoS parameter of HC-05 Bluetooth and NRF25L01 communication modules, during sending and receiving process among nodes. We assume that the sensor node and gateway node are attached on the limbs to catch the movement. We use Quality of Service (QoS) parameters such as delay, jitter, and packet loss, to analyze the impact of movement on communication modules. Based on the experimental result, it was found that the average value of delay and jitter for booth communication modules was slightly influenced by the speed of the sensor node movement. During the sensor node movement and data transmission, we found that the NRF24L01 module have a lower delay and jitter value than Bluetooth HC-05 module. The percentage of packet loss tends to be stable at 0% value, even though the speed value becomes higher.

Abstract

 Wireless Sensor Network (WSN) merupakan jaringan dengan skalabilitas yang sangat tinggi, dan memiliki jumlah sensor node yang sangat banyak. Untuk efisiensi biaya, sensor node banyak diterapkan dengan menggunakan Arduino. Arduino merupakan papan rangkaian elektronik open source yang di dalamnya terdapat chip mikrokontroler. Dengan keterbatasan resource yang dimiliki oleh Arduino, efisiensi komputasi yang ada di dalam sensor node harus diperhatikan. Salah satunya berkaitan dengan proses komunikasi dan pengiriman data dari sensor node ke sink node (gateway). Restful web service merupakan salah satu protokol komunikasi yang memanfaatkan HTTP. Protokol ini dikenal memiliki efisiensi yang cukup tinggi, di samping karena interoperabilitasnya untuk digunakan pada berbagai platform. Dalam makalah ini akan diuraikan hasil dari implementasi model pull message dengan menggunakan restful web service, pada komunikasi antara sink node (gateway) dengan sensor node, di dalam infrastruktur WSN. Dalam penelitian yang dilakukan, digunakan mikrokontroler Arduino sebagai sensor node, dan Raspberry Pi sebagai sink node. Selain itu juga diimplementasikan mekanisme thread untuk menangani multi-process yang berjalan di dalam sensor node. Hasil dari pengujian menunjukan bahwa interval sensing, ukuran data, dan jumlah sink node yang melakukan request, tidak begitu berpengaruh terhadap ketersedian free memory heap pada sensor node. Sedangkan ukuran dari data hasil sensing yang dikirim mempunyai pengaruh terhadap request-response time.    Wireless Sensor Network (WSN) infrastructure has very high scalability, which is composed of a large number of the sensor node. For cost efficiency, sensor node broadly deployed using Arduino. Arduino is the open-source electronic circuit board, which has embedded microcontroller chipset. Due to limited resource, the efficiency of computation inside Arduino must be considered during the development of sensor node. One of them is related to communication and data delivery process between the sensor node and sink node. Restful Web Service is one of communication protocol framework which uses HTTP protocol and claimed to be the most efficient Web Service. As well as the other web services, Restful also support high interoperability of communication. In this paper we describe the implementation of pull message mechanism on WSN communication between the sensor node and sink node, using Restful Web Service. We implemented sensor node using Arduino board, and sink node using Raspberry Pi. We also used thread mechanism to handle multi-process that run in the sensor node. The results of the study show that the interval time in sensing, data size, and the number of sink node which makes requests, didn’t give too much influence in the availability of free memory heap in the sensor node. While the size of sensor data that was sent to sink node have an influence on a request-response time.

Abstract

As a communicable disease, the majority of pneumonia cases are brought on by bacteria or viruses, which cause the lungs' alveoli to swell with fluid or mucus. Pneumonia may arise from this and further making breathing challenging since the lungs' air sacs are unable to contain enough oxygen for the body. Pneumonia may generally be diagnosed clinically (by a physician based on physical symptoms) as well as through a photo chest radiograph, CT scan, and MRI. In this case, the lower cost of a chest radiograph examination making it as one of the most popular medical imaging tests. However, chest radiograph photo readings have a disadvantage, where it takes a long time for medical staff or physicians to identify the patient's illness since it is difficult to detect the condition. Therefore, an identification of chest radiograph imagery into various forms using machine learning becomes one way to address this issue. This research focuses on building a deep neural network model using techniques from the Generative Adversarial Network algorithm. GAN is a category of machine learning techniques using two models to be trained simultaneously, one is a generator model to generated fake data and the other is a discriminator model used to separate the raw data from the real data set images. The dataset used is Chest X-Ray images obtained from repo GitHub and repo Kaggle totaling 5,863 with normal data 1583 images and pneumonia data 4273 imagesThe results showed that the use of the Generative Adevrsarial Network method as augmentation data proved to be more effective in improving the generalization of neural networks, this can be seen from the results the result of the accuracy value obtained is 97%.

Abstract

Indonesia’s coffee industry plays a crucial role as a major export, making a significant contribution to the country’s economy by generating foreign exchange. The quality and quantity of coffee production depend on various factors such as humidity, rain, and fungus that can cause rust diseases on coffee leaves. These diseases can spread quickly and affect other coffee plants quality, leading to decreased production. To address this issue, CNN with VGG-19 architecture model was utilized to identify coffee plant diseases using image data and the python programming language, which in previous studies used MATLAB as their platform. In addition, VGG-19 with image enhancement and contouring data for pre-processing step has a more profound learning feature than the method used in the previous studies, AlexNet which makes the structure of VGG- 19 more detailed. The dataset used in this paper is Robusta Coffee Leaf Images Dataset which have three classes, namely health, red spider mite, and rust. The VGG-19 model attained F1-Score of 90% when evaluated using the testing data with ratio 80:20, where 80% is training data, and 20% is validation data. This paper employed 0.0001 learning rate, batch size 15, momentum 0.9, 12 training iteration, and RMSprop optimizer.

Abstract

The growing number of smartphones, particularly Android powered ones, has increased public awareness of the security concerns posed by malware and viruses. While machine learning models have been studied for malware prediction in this field, methods for precise identification and classification still require improvement for the perfect detection of malwares and minimizing the cracks on machine learning based classification. Detection accuracy that ranges from 93% to 95% has been observed in prior research, indicates room for improvement.  In order to maximize the hyperparameters, this paper suggests improving the Random Forest method by introducing the grid search algorithm which isn’t present in previous studies. A significant increase in classification accuracy is the main aim of the research. We exhibit an outstanding 99% accuracy rate in detecting malware contaminated programs, demonstrating the significance of our technique. The proposed method can be seen as a huge improvement over existing models, achieving near perfection in detection, in contrast to which typically obtained by previous models with the accuracy rate of 95% max on the same dataset. Our approach achieves such high accuracy and provides a novel remedy for the limits of the Android based platforms, particularly when program processing resources are limited. This study confirms the effectiveness of our improved Random Forest algorithm, points to a paradigm shift in malware detection, and heightened cybersecurity measures for the rapidly growing smartphone market.

Abstract

This paper develops a Machine Learning (ML) model to classify the sentiment of review aspects in the peer review text. Reviewers use the review aspect as paper quality indicators such as motivation, originality, clarity, soundness, substance, replicability, meaningful comparison, and summary during the review process. The proposed model addresses the critique of the existing peer review process, including a high volume of submitted papers, limited reviewers, and reviewer bias. This paper uses citation functions, representing the author's motivation to cite previous research, as the main predictor. Specifically, the predictor comprises citing sentence features representing the scheme of citation functions, regular sentence features representing the scheme of citation functions for non-citation sentences, and reference-based representing the source of citation. This paper utilizes the paper dataset from the International Conference on Learning Representations (ICLR) 2017-2020, which includes sentiment values (positive or negative) for all review aspects. Our experiment on combining XGBoost, oversampling, and hyper-parameter optimization revealed that not all review aspects can be effectively estimated by the ML model. The highest results were achieved when predicting Replicability sentiment with 97.74% accuracy. It also demonstrated accuracies of 94.03% for Motivation and 93.93% for Meaningful Comparison. However, the model exhibited lower effectiveness on Originality and Substance (85.21% and 79.94%) and performed less effectively on Clarity and Soundness with accuracies of 61.22% and 61.11%, respectively. The combination predictor was the best for the 5 review aspects, while the other 2 aspects were effectively estimated by regular sentence and reference-based predictors.
