Mengamankan Perangkat Jaringan Dari Serangan DDoS Menggunakan Fitur Firewall-RAW di Router MikroTik

2024-04-09T16:32:30+02:00

DDoS (Denial of Service) attacks are a serious threat in network security that can cause services to become unavailable due to unusually high traffic volumes. This research aims to secure network devices from DDoS attacks by using the Firewall-RAW feature on the MikroTik Router. In tests carried out using MikroTik RouterOS, DDoS attacks were effectively prevented by using firewall rules that were set to reject packets that exceeded a predetermined threshold. However, the test results also show that the CPU Load of the device is still affected by DDoS attacks, although to a limited extent. This emphasizes that protecting against DDoS attacks is not an easy task, but the use of firewall rules can help reduce the system load due to these attacks. The recommended next step is to ensure the router device has sufficient CPU resources to anticipate the impact of a DDoS attack that may occur in the future. However, it is important to remember that firewall rules are only an additional protective measure and do not guarantee absolute protection from DDoS attacks. Therefore, there is a need for a comprehensive security strategy and appropriate infrastructure improvements to reduce the risk of greater DDoS attacks

Analisa Rekomendasi Buku Bacaan Berdasarkan Histori Peminjaman di Perpustakaan Universitas Katolik Santo Thomas Medan Menggunakan Metode Algoritma Apriori

2023-12-08T15:38:35+01:00

As time goes by, the amount and scope of data used by society is increasing. Therefore, an effective method is 
needed to manage this data into information that can be reused. Data mining is a data processing technique used 
to identify new knowledge. Data processing can help humans in managing the collection and utilization of accumulated data. 
This research aims to explore association rules in reading book recommendations using the Apriori algorithm method. 
The implementation of the Apriori algorithm will apply association rules to find linkage patterns in book borrowing 
data at the Santo Thomas Catholic University Medan Library. By applying the Apriori Algorithm method to borrowing books
 in libraries, it is hoped that linkage patterns can be revealed which can serve as a guide for librarians in determining 
the required book preparation. This research specifically focuses on book borrowing data at the Santo Thomas Catholic
 University Medan library, with the hope of providing insight into visitors' reading needs and interests. 
It is hoped that the results of implementing the Apriori Algorithm can provide valuable information for 
librarians to make more focused decisio in determining the book collection to be prepared.

Sistem Pendukung Keputusan Penilaian Kinerja Guru Menggunakan Metode Simple Additive Weighting (SAW)

2024-01-29T19:20:39+01:00

Sangat penting untuk mengevaluasi kinerja guru secara berkala untuk meningkatkan kualitas sumber daya manusia guru. SMKN 1 Negeri Labu melakukan penilaian kinerja guru setiap 3 bulan sekali namun mekanismenya kurang efektif karena kurang transparan. Metode SAW merupakan bagian dari DSS yang digunakan untuk membantu menentukan keputusan berdasarkan data alternatif dan data kriteria. Pengolahan data diimplementasikan sesuai dengan perhitungan metode SAW untuk menentukan matriks keputusan dan kemudian melakukan perangkingan dari total data alternatif. Pada penelitian ini terdapat 20 guru yang dinilai dengan 9 kriteria penilaian, hasil perangkingan menunjukkan bahwa data alternatif A03 memperoleh nilai tertinggi, maka diputuskan bahwa A03 memiliki kinerja guru yang terbaik. Perancangan sistem yang dikembangkan dengan UML menghasilkan sistem penilaian kinerja guru. Penelitian ini bertujuan untuk membantu pihak sekolah dalam menentukan kinerja guru terbaik yang diolah secara sistematis oleh sistem. Saran dari pelaksanaan penelitian ini agar dapat meningkatkan keakuratan hasil perhitungan, disarankan untuk membandingkan hasil dengan metode berbasis DSS lainnya.

The large size of digital image files is an obstacle in their storage, transmission, and processing. Digital image compression is a solution to overcome this problem. The Elias Omega Code algorithm is one of the efficient and easy-to-implement lossless compression algorithms. This research aims to analyze the Elias Omega Code algorithm on digital images. The analysis includes: implementation of the Elias Omega Code algorithm for digital image compression, evaluation of the performance of the Elias Omega Code algorithm in terms of compression ratio and image quality, comparison of the performance of the Elias Omega Code algorithm with other image compression algorithms. The results of the study show that the Elias Omega Code algorithm can produce a high compression ratio with preserved image quality. This algorithm has better performance than the Huffman and LZW algorithms, but lower than the JPEG algorithm..

Pengukuran Silhouette Score dan Davies-Bouldin Index pada Hasil Cluster K-Means dan DBSCAN

2024-07-22T13:28:50+02:00

eval_uation of Clustering results is a critical step in unsupervised data analysis. Clustering algorithms such as K-Means and DBSCAN are often used, but choosing the right algorithm for a dataset can be challenging. Application of Silhouette Score and Davies-Bouldin Index as internal eval_uation metrics to eval_uate Clustering results from K-Means and DBSCAN. The K-Means and DBSCAN methods were chosen because of their popularity and ability to handle various types of data. The Silhouette Score provides a measure of how well each data point is placed in its own Cluster compared to other Clusters, while the Davies-Bouldin Index eval_uates how far away the Cluster is from the others. This research was carried out by implementing both algorithms on an experimental dataset, namely the employee performance dataset and comparing the eval_uation results using these two metrics. The experimental results of both eval_uation metrics provide useful insights in eval_uating the quality of employee performance Clustering from K-Means and DBSCAN. Thus, the use of the Silhouette Score and Davies-Bouldin Index can be an effective guide in choosing an appropriate Clustering algorithm for a dataset without the need for ground truth labels.

Penggunaan Model Klaster K-Means Dan Klasifikasi KNN Untuk Identifikasi Pengetahuan Matematika Mahasiswa

2024-07-22T17:16:04+02:00

Students' mathematical knowledge is an important factor that needs to be considered in the learning process majoring in Informatics Engineering. Students who have low mathematical knowledge will definitely have difficulty calculating and applying the algorithms used to solve programming and computing problems. The weaknesses that these students have can become obstacles to the future. By knowing students' mathematical knowledge, the learning process does not have to be adjusted to the student's level of knowledge, but further action is needed to increase students' mathematical knowledge. One way to find out students' mathematical knowledge is to classify students' mathematical knowledge. Classification of students' mathematical knowledge can be done using a very popular method, namely the K-Nearest Neighbor (KNN) method. However, in order for classification to be carried out, grouping must be carried out first to form classes from the results of grouping mathematical knowledge data. The grouping of students' mathematical knowledge data was carried out using the K-MEANS method. Data on students' mathematical knowledge was taken based on course grades for calculus 1, applied physics, calculus 2, statistics and probability, and discrete mathematics. The grades from several of these courses will be processed using K-MEANS and form three groups of mathematical knowledge, namely slow, sufficient, and fast. Thus, it was concluded that to determine the classification of slow, sufficient, and fast mathematical knowledge of students majoring in informatics engineering, it was carried out using the KNN method, but first the data was grouped using the KMEAN method.
