Abstract

Keamanan data merupakan salah satu aspek terpenting dalam teknologi informasi. Dengan tingkat keamanan yang tinggi, diharapkan informasi yang disajikan dapat terjaga keasliannya. Pada tugas akhir ini dibentuk suatu system yang mengamankan data dan informasi yang tersimpan pada computer dari gangguan para kriptanalis.Tahapan yang penulis lakukan untuk melakukan proses pembentukan sistem tersebut meliputi tahapan analisa permasalahan, algoritma dan flowchart beserta pemodelan struktur program dan desain antar muka aplikasi, sehingga aplikasi yang terbentuk menjadi mudah dipergunakan dan memiliki fungsi yang optimal. Dengan menggunakan Algoritma TEA yang merupakan algortim. Algoritma ini merupakan algoritma penyandian block cipher yang dirancang untuk penggunaan memori yang seminimal mungkin dengan kecepatan proses yang maksimal. Sistem ini dibangun menggunakan bahasa pemrograman Visual Basic .Net 2008.

Abstract

The internet has become a very important part of communication development in the world. Exchange of information over the internet has many advantages compared to other communication media, especially in terms of speed. But information sent via the internet, security cannot be accounted for. Tapping on confidential information, very often occurs in this communication media. Channels used by the internet are generally not safe channels. By using the lossy compression method, compression can only be applied to images that have similarities to themselves (self similiarity) so that the size of the image gets smaller and saves storage space and accelerates the sending of the image using internet media.

Abstract

SMK Swasta Mulia Pratama Medan is one of the teacher training high schools in the city of Medan that has the determination to become a superior institution and become a reference in learning innovation. in the implementation of education carried out for the concentration of networks in SMK Swasta Mulia Pratama Medan, specifically studied practice and theory in class and laboratory on a scheduled basis, but it turns out that the lessons delivered in class and laboratory are still felt to be lacking due to limited time and facilities in the laboratory itself, where the LAN network application module taught must be studied in groups alternately and this is a real obstacle for students who queue to learn LAN network tools and modules. The use of network simulation software is very important to facilitate the abstraction of Computer Network subjects. In the study, the impact and effectiveness of network simulators in the teaching and learning process of computer networks will be examined. The network simulator chosen is Cisco Packet Tracer

Abstract

Active involvement of church youth in ministry is essential for fostering spiritual growth and creativity among Christian youth. In today's digital era, social media serves as a powerful platform to promote church activities in an engaging and modern way. However, many youths lack the skills to design content that is visually appealing and aligned with digital trends. This community service activity aimed to enhance the ability of the youth at GPP Church, Jl. Pelajar, Medan, in creating creative social media content using design applications such as Canva and CapCut. The implementation method included initial observation, hands-on training, mentoring, and evaluation of the participants' work. The results showed high enthusiasm from the participants and their ability to produce creative content in the form of posters, reels, and promotional church event designs. This training successfully improved their understanding and skills in designing and using social media positively to support church events and outreach. Furthermore, it empowered the youth to become creative digital ambassadors for the church, staying relevant to current technological developments.
