Abstract

Penerapan Internet of Things (IoT) dapat membuat semuanya terhubung ke internet tetapi sistem IoT dapat menjadi sasaran yang sangat mudah untuk disusupi penyerang dengan menggunakan malware, lebih dari 1,6 miliar atau tepatnya 1.637.973.022 anomali traffic atau serangan siber (cyberattack) yang terjadi diseluruh wilayah Indonesia sepanjang tahun 2021, teknik machine learning dapat dimanfaatkan untuk proses pengklasifikasian anomali traffic dengan menggunakan algoritma k-nearest neighbour (KNN) sehingga dapat membedakan data traffic yang bersifat benign atau malicious. Data anomali traffic yang digunakan adalah dataset aposemat IoT-23, didalam dataset tersebut terdapat 23 dataset, lalu terbagi kedalam 20 dataset scenario malicious dan 3 dataset scenario benign. Namun dataset yang digunakan adalah 20 dataset scenario malicious. 20 dataset tersebut selanjutnya dilakukan data preprocessing supaya dapat digunakan untuk proses training model atau pengklasifikasian. Nilai akurasi yang didapatkan setelah proses training model sebesar 0.94 atau 94%, model yang sudah dilakukan training model dapat memprediksi traffic data baru kedalam benign atau malicious, data baru yang sudah disiapkan adalah sebanyak 25 data baru. Prediksi 25 data baru tersebut menghasilkan 20 data diprediksi benar atau sesuai dan 5 data diprediksi salah atau tidak sesuai, 5 data tersebut terbagi menjadi 3 data yang harusnya diprediksi benign dan 2 data yang harusnya diprediksi malicious.

Abstract

Purpose: High population growth and increasing consumption patterns have resulted in significant organic waste production. The public often does not understand the correct way to deal with the problem of organic waste, including public awareness regarding the need for its management. Therefore, a system is needed to recognize waste objects based on various types. Currently, much research in this field has been studying object recognition, for example, the implementation of the Convolutional Neural Networks (CNN) model. However, there are still various challenges that must be addressed, including objects with diverse visual characteristics such as form, size, color, and physical condition. This research focuses on developing a system that enhances object recognition of waste, specifically organic waste, using an Attention Convolutional Neural Network (ACNN). By integrating attention mechanisms into the CNN model, this study addresses the challenges of recognizing waste objects with diverse visual characteristics. The proposed system seeks to improve the accuracy and efficiency of organic waste identification, which is crucial for advancing waste management practices and reducing environmental impact. Methods: This research combines a CNN architecture with an attention mechanism to create a better object detection environment called Attention-CNN (ACNN). The ACNN architecture employed consists of one layer input, three convoluted layers, three max-pooling layers, one attention layer, one flattened layer, four dropout layers, and two dense layers arranged in a certain way. Result: The research result shows that the model CNN with attention mechanism (ACNN) was slightly better at 86.93% than the standard model of CNN, which accounted for 86.70% in accuracy. Novelty: In general, the current use of CNN architecture to address waste object recognition problems typically employs standard architectures, resulting in lower accuracy for complex waste objects. In contrast, our research integrates attention mechanisms into the CNN architecture (ACNN), enhancing the model's ability to focus on relevant features of waste objects. This leads to improved recognition accuracy and robustness against visual variability. This distinction is important as it overcomes the limitations of standard CNN models in handling visually diverse and complex waste objects, thereby highlighting the novelty and contribution of our research.
