Wajah merupakan salah satu karakteristik biometrik yang digunakan untuk mengenali seseorang selain karakteristik yang lain seperti ucapan; sidik jari; retina; dll. Wajah adalah struktur multidimesi yang sangat kompleks dan membutuhkan tehnik komputasi yang baik untuk pengenalan. Di dalam penelitian ini; penulis mengambil 10 pose wajah yang berbeda kemudian menggunakan metode PCA untuk pengoptimalan dalam mereduksi dimensi. Setelah citra original di ekstraksi menggunakan PCA maka akan di hitung tingkat kesamaan (similarity degree) antara gambar test dengan gambar training menggunakan metode jarak. Hasil dari penelitian ini adalah tingkat kesamaan yang dihasilkan setelah proses reduksi dan ekstraksi menggunakan PCA didapatkan rata-rata nilai untuk Canbera Distance adalah 77;59.

Segmentation is the most important thing in the object identification process. Because machine learning-based interest segmentation of true color images is the most difficult task in computer vision. Because in the segmentation process there is a separation between foreground and background from a 3 layer RGB image to a layer 1 process to get a complete image without noise, this greatly affects the level of accuracy in image identification. In addition, we use several image processing operators such as filters, holes and openarea to remove image areas that we do not need. Therefore, in this study, we tested the images on 5 types of medicinal flowers using k-means segmentation with values of k=2 and k=3, as well as the otsu method. Both methods of segmentation are carried out by each method to get the appropriate pattern. The goal is to get the important areas that can be calculated by the image identification algorithm. This research uses 250 images and produces 750 patterns for the identification process. The results obtained are 96% to identify the flower type taraxacum laeticolor Dahlst with the K-means k=2 segmentation method.

Kriptografi banyak digunakan untuk menjaga aspek keamanan informasi. Pada penelitian ini penulis mengkombinasikan dua kriptografi modern dengan tujuan untuk memperkuat keamanan pengiriman pesan. Untuk kriptografi modern pertama, penulis memilih algoritma XOR dikarenakan mudah diimplementasikan dan tidak sulit secara komputasional. Untuk kriptografi modern kedua, penulis memilih algoritma AES dikarenakan proses algoritma ini cepat dan juga kuat. Proses pengamanan pesan diawali dengan proses enkripsi plainteks menggunakan algoritma XOR untuk menghasilkan cipherteks pertama. Selanjutnya cipherteks dienkripsi lagi dengan algoritma AES sehingga menghasilka cipherteks akhir. Sedangkan untuk proses dekripsi, tahap awal cipherteks didekripsi dengan algoritma AES untuk mendapatkan cipherteks. Kemudian cipherteks didekripsi lagi dengan algoritma XOR untuk menghasilkan plainteks kembali. Hasil dari penelitian ini menunjukkan bahwa pengiriman pesan berjalan 100% antaran plaintext ke chipertext dan kembali lagi ke plaintext dengan selisih waktu enkripsi dan dekripsi yaitu 0,13 dan 0,9 detik.

The network administrator is a person who is responsible for managing computer networks. One of the duties of a network administrator is network monitoring because errors on the server and services running on the server cannot be known when it happened. This can be difficult if the administrator is far from a surveillance center. A network Monitoring System is a system that helps Network Administrators in supervising and managing computer networks that exist in an agency. By using the system that will be implemented in this research, the computer network monitoring process can be monitored remotely, anywhere and anytime as long as it is connected to the Internet network. With this Network Monitoring System, it is hoped that in the long term PT Cyber Network Indonesia can implement an integrated and well-monitored Internet network system. Test results using Network Monitoring Zabbix, generate real-time data regarding bandwidth usage, problem logs and resource availability.
