Abstract

Decrease in learning outcomes in operating systems courses. The decline in learning outcomes is caused by the current corona virus pandemic. Which causes face-to-face lectures to be online. Researchers use project base learning to improve learning outcomes. The application consists of 2 cycles, namely Diclus 1 which is 80.12% with the number who did not pass, namely 16 students, researcher evaluating the learning process so that in cycle 2 it increased by 83.73%. With the student’s who did not pass. It can be concluded that the base learning method can be used to improve learning outcomes during the COVID-19 pandemic.

Abstract

The use of drugs, especially in Sumatera Utara, Indonesia, has a fairly large increase and requires serious efforts. EDUDA is an application that can help students form their resilience assisted by counseling guidance teachers, parents, and peers in forming good character. The educational application has self-defense materials and direct assessment of students' self-resistance which can be seen by the counseling teacher as an evaluation material for improving the quality of student development. based on the results of the implementation of educational media in schools, namely in phase 1 the increase was 7.3 with an average of 84.55, in phase 2 the increase was 3.24 with an average of 87.73. whereas in phase 3 the increase was 3.27 with an average of 91.06. the increase in phase 3 has been proven in building students' self-resistance in preventing drugs

Abstract

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

Abstract

keberhasilan hasil belajar diperoleh dengan kemampuan guru dalam menguasai media pembelajaran. Di zaman sekarang ini pengunaan ICT dalam pendidikan semakin pesat. Dan menghasilkan pembelajaran yang menarik, kapan, saja dan dimana saja. Aplikasi moodle mampu memberikan beragam fasilitas yang menunjang kegiatan guru selama proses belajara mengajar. Selama observasi 1 yang dilakukakan oleh peneliti kentutasan guru dalam menguasai moodle mencapai 63.25%. sedangkan persentase yang tidak lulus mencapai 36.75% dari hasil tersebut maka dilanjutkan pada observasi yang 2. Observasi 2 guru memperoleh nilai ketuntasan mencapai 92.25 %, sedangkan persentasi yang tidak lulus mencapai 7.75%. peningkatan hasil belajar ini deperoleh dari pemebimbingan yang tidak lepas dari guru mata pelajaran kepada peneliti melalui fasilitas seperti aplikasi Whatsap, dan Google meet sehingga manfaat dapat dirasakan langsung oleh guru yang mengikuti pelatihan moodle.

Abstract

Preparation of course schedules is the core activity of learning and learning. This is felt by study programs, where assignments are arranged through lecturer assignments, to class determination and class schedule dissolution, therefore the right application is needed to be able to arrange schedules automatically, then by using the k-means method you can arrange schedules correctly , in designing this application requires a prototyping application development method which gives good results where the clusters formed reach 17 clusters where the course schedule is made with the results of the Means Sequence Error in cycle 1 which is 65.66% with an accuracy of 54.06%. so that it is continued in cycle 2 the MSE value is 87.55% with an accuracy of 84.03%. The K-Means algorithm can accurately determine course schedules in the faculties of computer science and information technology.
