Perlintasan kereta api yang ada di Indonesia masih banyak yang belum memiliki fasilitas yang memadai contohnya alat pemantau keamanan perlintasan kereta api sehingga petugas pos yang bekerja mengalami kesulitan dalam memantau keamanan di area perlintasan kereta api. Selain itu, sistem membuka dan menutup pintu perlintasan masih dilakukan secara manual. Saat ini banyak pengendara sepeda motor maupun pengendara roda 4 (mobil) yang menerobos lampu lalu lintas (trafic light) dan melanggar rambu lalu lintas karena itu dapat membahayakan pada pengemudi kendaraan.kurangnya kesadaran diri untuk keselamatan saat berada diperlintasan kereta api yang berpalang ,maka timbulah ide untuk merancang sistem pengamanan lalu lintas yang diharapkan bisa mengatasi tidak dislipinnya pengemudi kendaraan, Metode yang dilakukan merancang alat yang juga menggunakan sensor dipasang dibawah rel kereta api, sitem yang dibangun menggunakan sistem pemrograman arduino Uno. Dari hasil perancangan alat dan juga dilakukan pengujian apabila kereta api melintas dengan jarak 50 meter maka sensor ultra sonic bekerja membaca program, palang kereta akan turun secara otomatis, sehingga ketika sensor ultra sonic bekerja maka program akan bekerja untuk menaikan aspal penghalang, untuk mengurangi angka kecelakaan saat kereta api melintas

Knowledge transfer, or better known as knowledge sharing, is the most important thing in the world of education. Not a few sources are used as learning references, ranging from printed books, ebooks, journals and various other sources. In addition to references, media or containers in the process of exchanging knowledge are always a hot topic to be discussed. This can be seen from the competition in the world of education in building a portal or academic information system that will be used as a medium that can be accessed by students anytime and anywhere, to support the smooth learning process. Also, like the Electrical Lighting Installation Technique, the development is very fast with a variety of methods and ways. In books, many tell about Electrical Lighting Installation Techniques, also on the internet and on YouTube. But it doesn't explain system-specific how it works. With the holding of PkM, the socialization of the installation of a series of electrical lighting installations is expected to help the community/students understand it
