Abstract

Penelitian ini bertujuan untuk menganalisis dampak serangan Denial of Service (DoS) terhadap performa dan ketersediaan layanan web, dengan menggunakan alamat domain hydrolevi.foxlust.my.id sebagai sampel pengujian. Topik ini dipilih karena serangan DoS dapat menyebabkan kerugian finansial dan kerusakan reputasi yang signifikan bagi pemilik situs web. Metode yang digunakan adalah pendekatan eksperimental melalui simulasi serangan menggunakan alat slowhttptest untuk mengukur respons server terhadap serangan Slow HTTP DoS. Hasil penelitian menunjukkan bahwa serangan DoS menyebabkan penurunan performa layanan web yang signifikan, memperlambat respons terhadap permintaan pengguna, dan meningkatkan risiko kesalahan sistem. Visualisasi menggunakan EtherApe mengindikasikan peningkatan lalu lintas jaringan yang berlebihan, sehingga layanan web tidak dapat diakses setelah serangan berjalan selama 171 detik. Hal ini menegaskan bahwa server tidak mampu menangani beban serangan tersebut. Oleh karena itu, sangat penting bagi pemilik server untuk menerapkan langkah-langkah pencegahan seperti peningkatan kapasitas server, implementasi solusi anti-DoS, dan penggunaan jaringan Content Delivery Network (CDN). Penelitian ini menekankan pentingnya kesiapsiagaan dan langkah-langkah mitigasi dalam menghadapi ancaman keamanan siber guna memastikan kelancaran layanan web.

Abstract

Enhancing the productivity and quality of Balinese cattle is a crucial goal for improving livestock management practices in Indonesia. Traditional evaluation methods used by farmers are often subjective and inconsistent, leading to inaccuracies in cattle classification and limiting the effectiveness of breeding and selection processes. To address these challenges, this study proposes a Fuzzy Inference System with Certainty Factor (FIS-CF) to improve cattle classification by providing more objective and reliable grading criteria. The model utilizes key physical parameters, including shoulder height, body length, and chest circumference, as input features to categorize cattle into three quality classes. A diverse dataset was collected from the People's Animal Husbandry School (SPR) and various farms across Indonesia to evaluate the model's performance. The FIS-CF model achieved a classification accuracy of 95.93% and a balanced accuracy of 96.20%, outperforming traditional methods that rely on subjective assessment. These results demonstrate that the proposed model provides a consistent, scalable, and data-driven solution for livestock classification, helping farmers make more informed decisions in cattle selection and breeding. Additionally, the model addresses key limitations of current practices by reducing reliance on manual evaluations, which often vary between assessors. The findings highlight the potential for wider adoption of the FIS-CF model across the livestock sector to improve productivity and streamline herd management processes. Future research will aim to refine the model further by incorporating additional parameters, such as age and weight, and expanding its validation to larger datasets covering different cattle breeds and farming environments to ensure broader applicability in sustainable livestock management.

Abstract

Permintaan brokoli di Indonesia terus meningkat 15% sampai dengan 20% per tahun. Sayangnya supply masih terbatas dan kualitas masih kurang. Untuk menentukan kualitas brokoli diperlukan adanya proses grading yaitu proses pemeringkat brokoli menjadi grade A, B dan C berdasarkan tiga parameter utama yaitu warna, ukuran, dan bentuk. Sayangnya, tidak semua petani memahami mengenai proses grading tersebut. Hal ini menyebabkan kerugian pada petani dan pengusaha brokoli. Penelitian ini bertujuan untuk mengembangkan algoritma grading menggunakan Convolusional neural network (CNN) berdasarkan 2 buah citra yaitu citra kepala brokoli dari tampak atas dan tampak samping. Dataset pada penelitian ini sebesar 600 data. Teknik yang digunakan ialah modifikasi beberapa model deep learning yaitu ResNet50, EfficientNetB2, VGG16 pada bagian layer klasifikasinya, lalu dibandingkan dengan hasil akurasi dari masing-masing outputnya. Penelitian ini juga menggunakan metode ensemble learning dimana menggunakan kombinasi dari 3 fitur berbeda. Fitur warna, ukuran dan bentuk digabungkan pada proses training dan testing untuk melakukan klasifikasi grade brokoli. Pada fase testing digunakan teknik voting untuk pengambilan keputusan grading. Akurasi terbaik ada pada model ResNet50 dengan hasil klasifikasi brokoli sebesar 90% yang didapatkan melalui penggunaan 5 dense layer pada layer klasifikasi, sehingga mampu melebihi hasil akurasi dari beberapa model deep learning lainnya. Algoritma dari penelitian ini menawarkan solusi grading yang lebih objektif dan konsisten dibandingkan sistem manual, sehingga petani dan pengusaha brokoli dalam meningkatkan efisiensi, mengurangi kerugian, dan memastikan kualitas produk yang lebih baik bagi konsumen.   Abstract The demand for broccoli in Indonesia has been increasing by 15% to 20% annually. However, supply remains limited, and quality control is inadequate. To assess broccoli quality, a grading process is required, classifying broccoli into Grades A, B, and C based on three primary parameters: color, size, and shape. Unfortunately, not all farmers possess sufficient knowledge of this grading process, leading to financial losses for both farmers and broccoli businesses. This study aims to develop a grading algorithm using a Convolutional Neural Network (CNN) based on two images, namely a top-view and a side-view image of a broccoli head. The dataset comprises 600 samples. The methodology involves modifying the classification layers of several deep learning models, namely ResNet50, EfficientNetB2, and VGG16, and comparing their classification accuracy. Additionally, an ensemble learning approach is employed, integrating three distinct features—color, size, and shape—into the training and testing phases for broccoli grading. The voting technique is utilized in the testing phase to enhance decision-making in the grading process. Experimental results indicate that the ResNet50 model achieves the highest classification accuracy at 90%, attributed to the incorporation of five dense layers in the classification stage. This performance surpasses that of other deep learning models. The proposed algorithm provides a more objective and consistent grading system compared to manual methods, enabling farmers and broccoli enterprises to enhance efficiency, reduce financial losses, and ensure higher product quality for consumers.

Methods: The methodology of this research includes literature study, data collection, data preprocessing, image classification, model evaluation, integration of CNN and random forest models, and estimation of nutritional content based on feed images. We collected 99 samples of broiler chicken feed from online stores in various regions of Indonesia, particularly Java. Next, we took pictures with a smartphone and analyzed the nutritional content using near-infrared spectroscopy. Preprocess the data by enhancing the dataset (color space and data augmentation). We use Convolutional Neural Network (CNN) for the classification of broiler feed images. The performance of the CNN model is evaluated using a confusion matrix. We integrate CNN and Random Forest Regressor (RFR) to estimate nutritional content from the features of broiler feed images. Result: The performance evaluation shows that the CNN (VGG-16) model is 0.9744% accurate and the RFR model has the highest R2 value of 0.8018. The benefits of this research include faster, more efficient, and automated feed quality measurement compared to traditional methods; maintaining feed quality standards; and avoiding health risks for livestock. Novelty: This research introduces an intelligent model to estimates the nutritional content of broiler feed images by integrating a CNN model with an RFR.

Abstract

The rapid increase in internet users has driven the development of WiFi networks, which play a crucial role in providing secure internet access, especially within Industry 4.0 and Industry 5.0 environments that rely on efficient data exchange. Penetration testing (pentest) is a vital approach for auditing and evaluating the security level of WiFi networks. Several frameworks such as PTES, PETA, and ISSAF are often used as references, although only a few are explicitly designed for WiFi networks. This study proposes a modification of the PTES framework to better align with the security characteristics of WiFi networks by providing relevant solution recommendations. The integration of the Boyer-Moore algorithm is employed as an efficient method to identify solutions for detected vulnerabilities. The implementation of this framework is demonstrated through testing the suggestion process, which produces solution recommendations based on vulnerabilities found during the pentest. The Boyer-Moore algorithm exhibits high efficiency in generating recommendations with a response time of 0.0000087 seconds.

Abstract

Vehicular Ad-Hoc Network (VANET) merupakan pengembangan jaringan wiresless yang melakukan komunikasi secara Inter Vehicle Communication (IVC). VANET memiliki mobilitas yang tinggi untuk setiap node nya sehingga jaringan komunikasi jenis ini adalah jaringan yang bersifat sementara dikarenakan node bergerak di lintasan dengan arah dan kecepatan yang dinamis. Dengan demikian, pengiriman paket data dari node sumber ke node tujuan menggunakan VANET memerlukan beberapa teknik komunikasi. Teknik terbaru komunikasi VANET saat ini adalah menggunakan SDN (Software Defined Network) yang berbasis geographic (SDGR) sebagai control plane dalam mengontrol komunikasi ad-hoc antar node. Dalam membentuk topologi jaringan komunikasi, SDGR mencari nilai jalur terpendek antar node dan kepadatan node yang tinggi. Tujuan utama penelitian ini melakukan analisis konsep protokol perutean (routing protocol) SDGR dan dilakukan pengembangannya dengan mempertimbangkan arah rute (SDGR+R). Pada SDGR+R, penambahan basis arah rute menggunakan multicast. Selanjutnya, dilakukan perbandingan kinerja antara SDGR dan SDGR+R. Hasil simulasi menunjukkan SDGR+R memiliki kinerja lebih baik daripada SDGR dalam hal latency sebesar 1.88% dan packet delivery ratio (PDR) sebesar 8.12%. Perancangan protokol perutean SDGR+R menambah ide pengembangan teknologi pada VANET untuk masa mendatang. AbstractVehicular Ad-Hoc Network (VANET) is a wireless network developed for communication on Inter-Vehicle Communication (IVC). Each node in a VANET has high mobility so that this type of communication network is a temporary network because the node moves on the track with dynamic direction and speed. Thus, sending data packets from source node to destination node using VANET requires some communication techniques. The latest technology for VANET communication is to use SDN-based geographic-based SDN (SDGR) as a control plane in controlling Ad-hoc communication between nodes. In forming the communication network topology, SDGR looks for the shortest path value between nodes and high node density. The main objective of this research is to analyze the concept of SDGR routing protocol and to develop it, considering the direction of the route (SDGR+R). In SDGR + R, the addition of route base directions uses multicast. Next, we compare the performance between SDGR and SDGR+R. Simulation results show SDGR+R has better performance than SDGR in terms of latency of 1.88% and packet delivery ratio of 8.12%. The design of the SDGR+R routing protocol gives to the idea of technology development on VANET in the future.
