Dalam sebuah instansi, sering kali terjadi permasalahan saat jam kerja berlangsung yang kemudian membutuhkan bantuan bagian pelayanan dalam menyelesaikannnya. Maka dari itu, dibuatlah Emergency Button Wireless untuk mempermudah dalam proses pemanggilan. Dengan menggunakan modul RF 315/443 MHz Transmitter-Reciever, alat ini merupakan alat yang bersifat independent. Kelebihan penggunaan Arduino ini dapat digunakan untuk membedakan dari titik mana yang membutuhkan bantuan.
It is necessary to make a monitoring system for the amount of electricity that includes voltage, current, power and the amount of electricity consumption. In this research, carried out in a building that has a 3-phase current with a power of 197 KVA. The analysis used the Kolmogorov-Smirnov normality test method. The Kolmogorov-Smirnov normality test compares the current distribution in the building with the current which is transformed into a Z-score form and is assumed to be normal. In the data analysis, the results of Asymp. Sig. (2-failed) has a value of 0.2. This, this shows the data has been normally distributed
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
