This Community Service Activity as one of the Tri Dharma of Higher Education aims to provide tools and training for multimedia-based learning systems at the Nusantara Islamic Junior High School and Madrasah Ibtidaiyah Sirojul Athfal 5. There is a decision from four ministers (Minister of Education and Culture, , Minister of Home Affairs, and the Minister of Health) to open Limited Face-to-face Learning activities in schools starting in July 2021, requiring all schools to prepare to learn in accordance with the Covid-19 protocol. The implementation of learning is still done in a limited manner, so a method is needed so that the achievement of the material can be given according to the target. The implementation steps include Distance Learning, which will make it easier for teachers and students to use the Learning Management System (LMS). This type of LMS training will make it easier for teachers to provide online visual teaching, assign assignments, arrange assignment collections, give daily or semester exams. Analysis of the implementation of this service activity was carried out by giving questionnaires to 21 participating teachers to see the effect of perceptions of usefulness, convenience, service quality, use, and effectiveness of Google Classroom on the learning process at partner schools.In general, the results of the questionnaire show that the use of Google Classroom can support a hybrid learning system in partner schools. Keywords— Covid-19 protocol, Google Classroom, learning management system, multimediabased learning systems   Kegiatan Pengabdian Kepada Masyarakat sebagai salah satu Tri Dharma Perguruan Tinggi ini bertujuan untuk memberikan perangkat dan pelatihan sistem pembelajaran berbasis multimedia di Sekolah Menengah Pertama Islam Nusantara dan Madrasah Ibtidaiyah Sirojul Athfal 5. Adanya keputusan dari empat menteri (Menteri Pendidikan dan Kebudayaan,  Menteri Dalam Negeri dan Menteri Kesehatan) untuk membuka kegiatan Pembelajaran Tatap Muka Terbatas di sekolah mulai bulan Juli 2021, mengharuskan semua sekolah untuk mempersiapkan pembelajaran yang sesuai dengan protokol Covid-19. Pelaksanaan pembelajaran masih dilakukan secara terbatas, sehingga diperlukan metode agar pencapaian materi bisa diberikan sesuai sasaran. Langkah pelaksanaannya diantaranya melalui Pembelajaran Jarak Jauh (PJJ), dimana akan lebih memudahkan guru dan siswa jika menggunakan Learning Management System (LMS). Pelatihan sejenis LMS ini akan memudahkan guru dalam memberikan pengajaran visual secara online, memberikan tugas, mengatur pengumpulan tugas, memberikan ujian baik harian atau pun semester.

In the world of education there is already a curriculum that must be carried out with learning outcomes that must be achieved by students, as well as lecturers who also have duties as facilitators in these achievements. With the Learning Outcomes, it makes students have the ability or competence in accordance with the requirements to meet the predefined study program profiles. One of the competencies that graduates of the Broadband Multimedia field must achieve is in the field of data processing including data compression. The most widely used data compression technique is the Huffman code. Some research on the Huffman code has been done a lot, and someone has made the Calculator application. The calculator is used to determine the code for each character. The code for each character is not fixed, depending on the frequency of appearance in a text. The more often the character appears, the shorter the code. In this study, it has proven that the feasibility of the Huffman Calculator as a tool for Learning Outcomes can be done where data compression with language variables, in this case English and Bahasa Indonesia to the compression ratio, produces the same compression ratio, which ranges from 1.51 to 1.64 for Bahasa Indonesia while English is 1.56 to 1.83, with the average entropy for English 4.35 and Bahasa Indonesia 4.41.   Keywords: competence , data compression,  huffman code, learning outcomes.
