SMA Negri 6 Binjai, merupakan lembaga pendidikan formal kepada anak usia sekolah. SMA Negeri 6 Binjai bertempat di Jalan A.R. Hakim No 66 A Kelurahan Nangka, Kec. Binjai Utara, Kota Binjai dengan jarak ± 4,2 Km dari STMIK Kaputama. Mata pelajaran komputer yang diberikan kepada siswa/i SMA Negeri 6 Binjai masih terbatas pengetahuan komputer dasar. Berbekal pengetahuan dasar tersebut, tentunya siswa/i harus mengembangkan kembali kreativitasnya dalam dunia digital. Oleh karena itu, siswa/i SMA Negeri 6 Binjai sebagai generasi milenial harus dapat memanfaatkan dunia digital untuk meningkatkan kemampuan yang dimiliki sehingga berguna sebagai salah satu bekal dalam menghadapi persaingan dalam dunia kerja nanti. SMA Negeri 6 Binjai tidak memiliki mata pelajaran desain grafis, sehingga dilakukan kegiatan pengabdian kepada masyarakat untuk mengadakan sebuah pelatihan yang bertemakan desain grafis selama 2 hari. Melalui program pengabdian kepada masyarakat ini diharapkan dapat meningkatkan kreativitas siswa/i dalam pengetahuan dan kemampuan desain grafis. Peserta dapat mengenal desain grafis serta dapat mempraktekkan aplikasi yang digunakan untuk membuat desain grafis tersebut. Diakhir pelatihan, dilakukan kompetisi dimana peserta diminta untuk membuat rancangan kartu nama masing- masing.
This study aims to classify the assessment of the learning process at SMA Tunas Pelita Binjai T.A. 2018/2019 based on the average grade X, additional subjects applied technology, and student absenteeism classified using Matlab.The data is processed based on learning grouping as much as 2 clusters with different centroids, namely for cluster 1 the average value of even and odd semesters for class X (85.0), additional subjects of applied technology (86.3) and student attendance (2.4) and cluster 2 the average grades of odd-even semesters for class X (68.2), additional subjects of applied technology (70.3) and student attendance (2.4). In the final result, it can be seen that the grouping of learning at SMA Tunas Pelita Binjai with 100 data can be divided into 2 groups, namely group 1 with 62 data with an average value of odd and even semesters and high additional applied technology and student absenteeism. low grades are classified as students with good grades and group 2 as many as 38 data with an average value of odd, even semesters and low values of applied technology and high student absenteeism belonging to students who have poor grades.
This study is to solve the problem Cryptographic techniques used to protect and maintain the confidentiality of audio messages by changing audio messages into audio messages that cannot be played by doing the encryption process and can be played back after the audio message is decrypted. To protect audio messages, it is used in the process of encrypting and decrypting audio messages using the Advanced Encryption Standard (AES) method. The Advanced Encryption Standard (AES) uses symmetric key block passwords with varying key sizes of 128 bits, 192 bits, and 256 bits. The Advanced Encryption Standard (AES) method used is 128 bit key size and there are 10 rounds in the process of encryption and decryption. Audio messages that have been encrypted using the Advanced Encryption Standard (AES) method cannot be played by parties who do not know the key to encrypt and decrypt the audio message. Audio messages are protected and protected from irresponsible parties who want to damage or just listen to the audio message.
