Abstract

Peralatan yang bersifat induktif ini menyebabkan rendahnya nilai faktor daya listrik. Rendahnya nilai faktor daya (cos φ) dalam suatu sistem tenaga listrik adalah sebuah masalah yang harus diminimalisir. Dengan rendahnya nilai faktor daya akan menyebabkan kerugian bagi konsumen maupun bagi produsen listrik.Perbaikan faktor daya dilakukan dengan memasang kapasitor bank secara paralel dengan beban. Penggunaan relay pada proses switching kapasitor bank dapat menyebabkan gangguan transient yang dapat mempengaruhi kualitas tegangan. Air Coil digunakan untuk mengurangi gangguan transient pada proses switching.Hasil Pengujian dengan implementasi Air Coil pada kapasitor bank menunjukkan adanya perubahan nilai faktor daya, adapun hasil pengujian yang dilakukan pada pukul 06.00 untuk beban kipas angin 46 watt mengalami kenaikan nilai faktor daya sebesar 2 %, kipas angin 36 watt sebesar 2 %, televisi 80 watt sebesar 1 %.

Abstract

Abstract: This study aims to determine the design of an LPG gas leak detection system using Internet-based Nodemcu ESP866. LPG gas cylinders are an essential kitchen fuel for most people. In preparing the research, the authors first collected data by conducting a literature study to find out the schematic circuit, component datasheet, and how the components work. Based on statistical data from the fire department from January 2010 to August 24, 2010, there were 46 fire incidents in the DKI Jakarta area, with an estimated material loss of Rp. and many materials. With the results, we get from our tool. Namely, the Buzzer as an alarm, the LED as an indicator, and the DC Fan can be On when the sensor detects a leak in the gas cylinder. In conclusion, the tool can be integrated with a smartphone using Wifi. In testing the device, the measurement range is 5-30 meters. At a distance of 5 meters, it produces 4.76, and at a distance of 10 meters, the time difference is around 2 seconds slower for smartphones to receive notifications. At a distance of 20 meters, it produces 7.66 seconds; at a distance of 30 meters, the time difference is 2.5 seconds slower for smartphones to receive notifications.
