Abstract

XYZ is a manufacturing company located in the city of Batam. most of the activities of employees at PT XYZ Batam are still carried out offline like new employees, where HRD still checks every application sent by candidates via email for staff and post office for non-staff. The impact on PT. XYZ is if you are still using the current manual system, all job applications that will not be used will pile up. Meanwhile, email messages that are received in large numbers will cause spam and take a long time to choose, therefore the author will create and design online recruitment based on an information web system using the Decision Support System (DSS) method that can help HRD in the recruitment process The Decision Support System used by the author is the Simple Additive Weighting method, also known as summation. This method automatically selects prospective employees who have submitted applications through a system that matches their work experience, study program, and skills. Thus, Simple Additive Weighting is the most appropriate method for decision making in employee recruitment

Abstract

The rapid development of technology in the IoT (Internet of Things) field gave rise to the idea to create a final project entitled Charging Prepaid KWH Meters Using a 2D Plotter. The problem to be solved in the final project is to overcome the problem in terms of filling the Prepaid KWH Meter which is still done manually by pressing the keypad directly on the Prepaid KWH Meter, this will be a problem if the position of the Prepaid KWH Meter is difficult to reach or out of reach of hands, the second is to avoid direct contact with the Prepaid KWH Meter keypad so as to prevent the spread of the Covid 19 virus that can lodge in inanimate objects such as the Prepaid KWH Meter keypad. This final project uses the ThingSpeak IoT platform as a place to store and retrieve data via an internet connection and use the Android application as a place to remotely and monitor the status of Prepaid KWH Meters. Based on the tests that have been carried out, the number of steps needed by the stepper motor in theory and practice at a distance of 14 mm on the X axis and 9 mm on the Y axis, the error percentage is 1.785%. When ThingSpeak sends token data to the NodeMCU ESP8266 which can be seen on the Arduino IDE serial monitor, the average delay is 23.19 seconds. And in application testing there are 3 status conditions, namely the first "WAITING" status occurs when the token data transmission process is in progress or the 2D Plotter is working, the second "ADA LISTRIK" status occurs when the sensor does not detect the buzzer sound on the Prepaid KWH Meter, which The third status “TOKEN MAU HABIS” occurs when the sensor detects a buzzer sound on the Prepaid KWH Meter.

Abstract

Lo-Ra (Long Range) is a process of changing a certain periodic wave so that it becomes a signal capable of carrying information. LoRa technology offers a very attractive long term. Such as using low power and data transfer that is guaranteed security. Public networks that use LoRa networks will be able to provide a wider signal coverage. Compared to cellular networks in general, LoRa is a network that covers a wider range. Besides that, it is also easy to fit into the needs we need. This need is like any other electronic device that uses wireless installation. The making of this tool is a fire detector to reduce the impact of forest fires and has advantages over other tools, namely that many fire detection tools used do not meet criteria such as sending information that cannot reach long distances so that a tool that can solve this problem appears, namely Long Range ( LoRa), LoRa can anticipate lost GSM signal coverage. The purpose of this research is to detect and monitor the level of vulnerability to fire and provide information to officers in real time which will be displayed on the blynk. The results of this study obtained that this tool is able to detect forest fires up to a distance of 700 meters, if it exceeds that distance the reading will be error, this tool detects forest fires by reading the three sensors, if the three sensors have reached the threshold point, namely with a temperature sensor greater than 40 degrees Celsius, the humidity sensor value is less than 61%, and the smoke sensor value exceeds 2670 ppm, the tool will give a fire warning that will appear on the Blynk notification. at a distance of up to 700 m, the average delay for node 1 reaches 23.2 seconds and the average delay for node 2 reaches 54.5 seconds. And it can also be seen that the average percentage of temperature error obtained at node 1 reaches 4%, and the average error in humidity for node 1 reaches 6.4%, then the average percentage error temperature obtained at node 2 reaches 8.5%, and the average error at node 2 humidity reaches 18%.

Abstract

Polytechnic of Kampar is one of the universities in the palm oil sector in Indonesia. Every learning process will require an attendance. Attendance at the Polytechnic of Kampar is still using paper or manually. The drawbacks of attendance using paper are the possibility that the attendance book can be lost or scattered, the absence of attendance when the attendance book is lost, attendance uses a sheet of paper when the attendance book is lost, the number of paper uses, and so on. To overcome this, in this digital era, a lecturer attendance application was made using an QRcode based Android. This application is designed using Android Studio version 4.0, Code Igneter Framework and MySQL as a database. Hopefully, the application that is built can help overcome the shortcomings of attendance manually. After being tested, it can be seen that this application can solve problems in the manually attendance in Polytechnic of Kampar, so that in general this application can run as expected.
