Nowadays, digital image processing is not only used to recognize motionless objects, but also used to recognize motions objects on video. One use of moving object recognition on video is to detect motion, which implementation can be used on security cameras. Various methods used to detect motion have been developed so that in this research compared some motion detection methods, namely Background Substraction, Adaptive Motion Detection, Sobel, Frame Differences and Accumulative Differences Images (ADI). Each method has a different level of accuracy. In the background substraction method, the result obtained 86.1% accuracy in the room and 88.3% outdoors. In the sobel method the result of motion detection depends on the lighting conditions of the room being supervised. When the room is in bright condition, the accuracy of the system decreases and when the room is dark, the accuracy of the system increases with an accuracy of 80%. In the adaptive motion detection method, motion can be detected with a condition in camera visibility there is no object that is easy to move. In the frame difference method, testing on RBG image using average computation with threshold of 35 gives the best value. In the ADI method, the result of accuracy in motion detection reached 95.12%.

Kondisi saat ini dengan adanya wabah penyakit pandemi Covid 19 telah menimbulkan permasalah baru dalam penyelenggaraan pendidikan secara konvensional. Pertemuan tatap muka langsung antara guru dan siswa belum diizinkan untuk diselenggarakan. Salah satu cara yang dapat dilakukan adalah pembelajaran daring melalui jaringan internet. Metode Pembelajaran ini juga dilaksanakan oleh Sekolah Menengah Atas Negeri 2 (SMAN 2) Rumbio. Namun ada keterbatasan sarana fisik seperti jaringan internet dan perangkat komputer. Disamping itu juga keterbatasan kemampuan penguasaaan teknologi yang mendukung pembelajaran daring. Sambungan internet dilakukan melalui perangkat handphone dan belum ada koneksi internet yang baik. Lokasi sekolah yang cukup jauh dari pusat kota menyebabkan sulitnya mendapatkan akses internet melalui jaringan kabel. Salah satu cara yang dilakukan untuk mendapatkan akses internet adalah dengan memanfaatkan jaringan seluler. Untuk mendapatkan koneksi internet jaringan seluler diperlukan perangkat modem GSM. Koneksi internet yang telah diperoleh bisa dibagikan kepada beberapa komputer melalui jaringan baik secara wired maupun wireless. Selanjutnya perlu dilakukan pelatihan bagi para guru agar memiliki pengetahuan tambahan mengenai model pembelajaran daring. Fasilitas perangkat lunak yang banyak tersedia seperti Google Suite for education perlu dikuasai oleh guru, sehingga dapat dimanfaatkan dengan maksimal demi kepentingan para siswa. Program pengadaan dan optimalisasi jaringan internet sekolah untuk pembelajaran daring dalam masa pandemi covid 19 di SMAN 2 Rumbio Jaya sudah berhasil dilaksanakan dengan baik. Melalui penambahan perangkat jaringan dan modem internet, sarana akses jaringan internet untuk pembelajaran dapat lebih meningkat. Pelatihan pembelajaran daring dilaksanakan sesuai dengan kondisi dan kebutuhan para guru setelah dilakukan pemetaan melalui survey awal secara online. Hasil survey awal menunjukkan kemampuan yang masih terbatas dalam pengelolaan kelas dan pemanfaatan fasilitas yang disediakan google suite for education untuk pembelajaran daring, seperti pembuatan soal ujian online melalui penggunaan google form.
