This study aims to develop powtoon based animated video media. This research is research and development (Research and Development). The models are defining stage, design stage, develop stage, and disseminate stage. But in this study only up to the develop stage. The research was conducted at SD Negeri 050660 Kwala Bingai. The research subjects were 25 students of class V, consisting of 13 male students and 12 female students. The object in this study is a powtoon based animated video. Data collection techniques are observation, questionnaires, and tests. Based on the feasibility results by linguists with a percentage of 89.55% it is categorized as feasible, media experts with a percentage of 90.25% are categorized as very feasible, and material experts with a percentage of 93.80% are categorized as very feasible. Based on the trials that have been carried out, it is known that the results of the pretest trial with a percentage of 36% with students who did not complete as many as 22 people. Meanwhile, the results of the posttest trial with a percentage of 88% with 24 students who completed. From the results of the feasibility and effectiveness of powtoon based animated videos in Indonesian language learning for fifth grade students at SD Negeri 050660 Kwala Bingai it is said that it is feasible and effective to use.

The role of algorithms in software or programming is very important, so it is necessary to understand the basic concept of the algorithm. The sorting algorithm is, selection sort (sorting by selecting) is the process of sorting data according to certain rules so that they are ordered regularly. Sorting data consisting of some criteria have priority where the data is sorted by language PHP programming that provides the sort function to sort array data in ascending or descending order from smallest to largest. The sort function is sort data from smallest to largest digit or last letter of letters first each word prioritizes letters then numbers if the data is in that table data consists of a mixture of numbers and letters. The method used is searching the smallest element of the array and swaps it with the element in the first position, then this algorithm repeats the same thing again, namely looking for elements in second position, The process that will result from this system continues until all array elements successfully sorted.

Currently, especially in Indonesia, data leaks occur in domestic agencies and private e-commerce. From these problems, cryptographic researchers are needed to make the data difficult to read, this research forms cryptography through a substitution method which will determine the number of keys that have been used and generated back in the dictionary, in its implementation the researcher uses the Devops design method, this method uses 4 stages, namely 1. ) continues development, 2) continues testing, 3) continues integration, 4) continues development. The results obtained by the text can be encrypted and described perfectly and successfully as much as 15864 data, and consumes low resources

A country's development might be represented by its education system. The Indonesian government, through the Ministry of Education, Culture, Research and Technology make a breakthrough through Regulation of Minister of Education and Culture no. 3 of 2020 on the Independent Learning-Independent Campus (Merdeka Belajar Kampus Merdeka / MBKM) program. This policy provides private and state university students an opportunity to enrich and broaden their knowledge and competence in a real life settings. One of the implementations of this program is the industrial internship. In Dharmawangsa University, MBKM policy has been translated into an industrial internship program through collaboration with several companies and industrial sectors. In order to monitor its students activities during the internship, Undhar assigns a permanent lecturer as a field guide lecturer (Dosen Pembimbing Lapangan/DPL). The monitoring system presented in this paper was developed using Agile Scrum, which began with problem identification stage to system testing stage. This method was selected due to easier adjustability, as it allows further development following the needs. This work produced a web-based system for monitoring and reporting students internship activities, allowing students and DPL to communicate more easily related to the students internship activities.

At this time there are more and more types of medical devices which include goods, instruments or other tools including each component, part or equipment produced. Basically, many people have not been able or are still minimal in knowing medical equipment. One way to provide knowledge to the community is through socialization. Socialization equipped with media that is in accordance with technological developments will facilitate and greatly help the community, namely smartphone media using Augmented Reality technology using the Marker Based Tracking method. This research will build an application for the introduction of medical devices that will combine Augmented Reality technology and the Marker Based Tracking method with the Fisher Yates Shuffle algorithm. The purpose of this research is to produce an application for the introduction of medical devices based on Android and apply the Marker Based Tracking method in Augmented Reality technology with the Fisher Yates Shuffle algorithm in making random questions. The results of this study are in the form of applications that apply augmented reality technology and the Fisher Yates Suffle algorithm in introducing medical devices.

Whatsapp is a cross-platform messaging application that allows us to exchange messages without SMS fees, because WhatsApp uses the same internet data package for email, web browsing, and more. The WhatsApp application reportedly has improved the security system of applications that are end to end encryption (E2EE). This proves that the WhatsApp manager paid considerable attention to privacy and security issues for its users. In addition, it also implies an important matter where business actors have begun to realize that the application of cryptographic services is part of a very promising business strategy or even determines the present and future consequences. The consequence of implementing E2EE is the description encryption process that takes place at the application layer (OSI layer). Cryptography is a study that studies methods to send messages in secret (that is, encrypted or disguised) so that only the intended recipient of the message can decode and read the message. For this reason, cirptography is one method that can implement E2EE on whatsapp. One Time Pad (OTP) is a type of symmetry algorithm, each key is only used for one message. If the key is random (cannot be reproduced) and only used once, then the algorithm is perfectly safe. The MAC (Message Authentication Code) is an identifier to prove the authenticity of a document obtained by using meaningless messages obtained from processing some of the contents of the document using a private key .
