Abstract

Crimes such as theft and housebreaking are serious problems related to security. This problem often occurs when the homeowner is out of town or leaving the house for a few days. Therefore, an effective security system is needed so that the house is not easily broken into and can be monitored via smartphone by the owner. To minimize the crime rate, we designed a microcontroller-based automatic door lock. This automatic system can control the solenoid door lock and function as a home security. This study aims to develop a door lock and window security system based on a microcontroller and the Internet of Things. This system utilizes RFID to open the door which is processed by Arduino, as well as a PIR Sensor for double security which is processed using NodeMCU ESP8266. The smartphone functions as a medium for monitoring and opening the door. The NodeMCU ESP8266 microcontroller on the PIR Sensor is tasked with processing data so that when the sensor detects movement, the buzzer will sound and send a notification to the smartphone. The results of the study show that the automatic door lock can be accessed via RFID and applications on smartphones. The system can detect RFID at a distance of 3 cm with a response time of 2-5 seconds, and successfully detects movement in humans and animals with an accuracy rate of 86.67%.

Abstract

Universitas Jenderal Achmad Yani, whose major campus is in Cimahi City, is constructing a large-scale campus development, the size of which is directly proportionate to the quantity of energy consumed. This increase in electrical energy consumption can be minimized by utilizing environmentally friendly renewable energy sources to supply loads and reduce the use of existing energy from the grid (PT. PLN). This context supports a design proposal for the production of photovoltaic-based photovoltaic on the Universitas Jenderal Achmad Yani campus, particularly in two buildings with exceptional roof potential. In this paper, the modeling carried out aims to help supply renewable energy-based electrical energy. The design of PV on Grid Installation Engineering in Buildings at Universitas Jenderal Achmad Yani carried out in this paper includes PV placement layout, PV construction, and simulation using PVsyst. The rooftop-type grid-connected PV is modeled in the Faculty of Health Sciences and Technology (FHST) Building and the Rectorate Building, which are composed of PV panels, inverters, and other supporting components. Grid PV design and simulation modeling on the roofs of FITKES and Rectorate Buildings resulted in a total installable PV capacity of 420 kWp, an annual average Performance Ratio of 80.6%, and an average potential energy output of 702 MWh/year. This energy potential is undoubtedly proposed to fulfill future electricity needs.
