Public campus has a mandate to saving of electrical energy. Electrical energy consumption is often wasteful in building. There is tendency wasteful by user. Electronic equipment is often still turn on at idle time. Only a few students want to turn off the equipment and shut down the computer. Saving of electrical energy is not only at idle time but it can be improved into operational hour. It is not depending on idle time or operational hours, but depends on human presence. Implementation of electrical energy saving has to be supported by frugal behavior and equipment technology. In this study, we name system of smart detection and control to electrical energy (Sisdece). This system is consist of hardware and software. Hardware applies passive infrared sensor (PIR) sensor, wireless sensor network (WSN), microcontroller ESP32, access point, relay. Software use C++, hypertext preprocessor (PHP), hypertext markup language (HTML) and android studio. Result of measurement has been done in a month during November 2020. Average of energy saved is 12.51 kWh and total of electrical energy is 105.86 kWh. Comparison of energy saved to electrical energy is 11.81%. This is a significant reduction to electrical bill. The result is expected as benchmark of electrical energy management in Politeknik Negeri Medan (POLMED).

Attendance in Universitas Muhammadiyah Sumatera Utara (UMSU) uses the manual attendance method. So it is less effective to implement, because manual attendance is not environmentally friendly and in the process fraud can still occur. In addition, the health protocols that we should have implemented both on campus and in classrooms must still exist considering this is a post-pandemic. Based on these problems, the purpose of this research is to make a prototype of the entrance and attendance access system which is carried out by utilizing the features on the NodeMCU ESP32. The design step is divided into 2, namely hardware and software design. The manufacturing process for the door access system is carried out by utilizing the Gy906 temperature sensor as a body temperature detector, a relay to turn on the pump, an IR proximity sensor to detect people who are going out, and a servo motor as an open- or closed-door driver. Next, the process of making attendances is carried out using a barcode on the KTM (Student Identity Card) which is connected to the application that has been made so that the output for the presence can be seen on a google spreadsheet. This tool can make it easier to make attendance and access entrances and exits without touching the door.

Earthquake is natural event due to release of energy suddenly from within that creates seismic waves. The vibrations are usually caused by movement of earth's plates. It cannot be predicted when they are coming. Therefore, need to build an early warning system. It is for anticipation of save the community when an earthquake occurs. It provides solutions to minimize the impact of earthquake events. This system uses accelerometer sensor and arduino nano as a main controller and it is accompanied by Blynk application. This works for sent notification via smartphone. This tool has been successfully designed with manual testing to be able to see the sensitivity of earthquake sensor made. Accelerometer sensor works is using Tilt Method. Accelerometer sensor will tilt on surface as parable of earthquake. Accelerometer sensor will send vibration signal when earthquake occurs. Signal processing is done by Arduino nano as the main controller in system. If the signal is received by sensor then value of earthquake will be displayed on LCD screen. Status of earthquake was separated into 4 levels such as standby, alert, dangerous, dangerous and dangerous. After earthquake value appears on the LCD screen and the status is known then buzzer will sound. It indicates that the earthquake warning alarm is properly functioning. Next, NodeMCU also sends information to Blynk application, which is used as a notification and monitoring of earthquake conditions. Buzzer will sound as a warning alarm to notify peoples to save themselves. This sensor has three output coordinate points, namely X, Y, Z, which have analog values on Arduino Nano. This analog value can be converted into Richter Scale. Based on experimental results, an analog value is 100 – 400.

Earthquakes are vibrations that occur on the earth's surface due to the sudden release of energy from within the earth that creates seismic waves. Earthquakes are usually caused by movement of the earth's crust (plates). The frequency of an area, refers to the type and size of earthquakes experienced over a period of time. Often with the development of technology, it provides a solution to minimize the impact of earthquake events. For this reason, an earthquake warning alarm is needed as an early warning and anticipation of the community when an earthquake occurs. Therefore, researchers made a tool which uses the Accelerometer sensor and arduino nano as a controller and is accompanied by the blynk application as an earthquake early warning notification sent via smartphone. This tool is processed using an Arduino Nano microcontroller as a controlling component. The working system of this tool uses an 8 Volt lithium battery installed in series as a voltage source, which will be reduced to 5 Volts with a stepdown module, because by using a battery voltage of 8 Volts and coupled with a lot of load, the Arduino Regulator IC will experience overheating or heat up quickly. This tool has been successfully designed with manual testing to be able to see the sensitivity of the earthquake sensor made, by utilizing seismic waves that arise due to ground movement. This tool successfully detects earthquakes with horizontal and vertical vibrations, and this tool is quite effective because it does not detect vibrations generated in the surrounding environment. Based on the tests carried out, at an accelerometer sensor tilt angle of 90o the system reads an earthquake strength of around 7-10 Richter Scale (SR) with a WASPADA status
