Abstract

Microprocessor and microcontroller laboratories are type III laboratories that are in the electronics engineering study program majoring in electrical engineering, this laboratory serves the activities of student practices for microprocessor system courses, microcontroller systems and interfaces I and II and very large scale intergration (VLSI) programmable logic devices and programmable electronics. Laboran as manager and person in charge of the laboratory, every month submits reports on equipment support facilities and practice modules made manually to the head of the laboratory. Every day the laboratory staff must examine all equipment activities one by one such as computers and practice modules to find out the latest conditions. Seeing the problems above, we need a system solution that can provide fast, accurate, complete and integrated information as a whole. The purpose of this study is to produce an information system design for maintenance and repairs to microprocessor and microcontroller laboratories. The method used in this study analyzes the current system to create a conceptual model so as to produce a database diagram. Next, the design of the display includes the design of the application interface such as the reporter display, laboratory performance reports etc. To further maximize laboratory use and quality teaching and learning is expected that students, lecturers and staff will also participate by reporting damage to supporting facilities at the microprocessor and microcontroller laboratory.

Abstract

In this study, an information system was created to remind users of the length of sitting time to avoid the risk of health problems due to sitting too long. The device is designed and made in two parts, sitting cushion and application on the smartphone. In the seat cushion the limit switch sensor is placed to detect the sitting position and temperature sensor to detect the temperature of the bearing as an indicator of the long sitting. The data detected by the sensor will be sent to the microcontroller and prepared to be sent to the smart phone. The data to be displayed using an android application with Bluetooth communication. Display on the smartphone in human body posture accordance to user's sitting position. There are three body positions, namely the normal position, tilt to the left and tilt to the right. If the body position is tilted, then the smartphone will give an alarm warning to restore the sitting position to the normal position. The bearing temperature detection results will be displayed in the form of numbers with a green background as the indicator of the temperature is still normal, yellow if the bearing temperature rises and red if the temperature has exceeded the permitted normal limit. This means the user has been sitting too long and must stand or rest for a while. To remind the user to stand up, the smartphone will also give a warning by turning on the alarm.

Abstract

Modernization is indeed very influential in the lives of people today, with the existence of this modern era, everything is always related to technology. The place is far enough and to find out the condition of the excess current makes the PLN officials also have difficulty because there is no monitoring tool from the situation. From the description above, the author found the idea to make a Simulation System for Monitoring Overcurrent Systems in the PLN Phase One Phase Using a Microcontroller-Based Web. The tool uses the Arduino Mega microcontroller coupled with ACS712 Flow sensors, and Ethernet Shield Modules. The way this tool works is to detect the electric current that enters the Input from the electrical equipment load on the ACS712 sensor. In testing the author only uses 3 pieces of light as a burden to determine the state of excess current. If you use 1 load, the current that is read is 0.44A with a 100 Watt lamp power. And if the load is added by 1 load with 75 Watt of light power, the current that is read becomes 0.77A. Then the load is added with 1 lamp with a power of 60 Watt, then the current becomes 1.05A with the result at all three drop loads.
