Abstract

In the current era of the covid-19 pandemic, for employee attendance attendance is still using the attendance system with a finger print and in my opinion it is very dangerous in employee attendance at this time during the covid-19 pandemic, because the hands of employees who have been absent are left behind in the attendance machine and I think it can spread covid-19 to other employees who want to be absent, so that the use of a distributed system application on the mobile-based attendance information system at bpdashl wampu sei snake has a good impact on users, where users can avoid the spread of covid-19 with services digital attendance provided by the application that was built so that employees no longer have to queue at the attendance machine and avoid touching the attendance machine. To build a distributed system application on a mobile-based attendance information system at the office of bpdashl wampu sei snake using Adroid Studio. Therefore, the author raised the title of a distributed system application application on a mobile-based attendance information system at the BPDASHL Wampu Sei Snake office, so that the prevention of employee attendance is not contagious because there is no physical contact by reducing touch. With the design of a distributed system application on this mobile-based attendance information system, it is hoped that it can trigger other developers to innovate more in designing the next system

Abstract

Advances in technology today have provided many benefits in the use of electronic equipment that makes it easier for humans to carry out their daily activities. In the Industrial revolution 4.0, the first progress that can be felt is the internet of things or IoT. Iot has an important role in Industry 4.0, because it can connect everything to the internet network. Iot (Internet of Things) can be used in gardens to control garden lights and check temperature and humidity that can be operated remotely via the internet. This system utilizes sensors that can detect the amount of light intensity resistance that is used to turn on and off lights based on light intensity, sensors that can detect temperature and humidity that can be controlled and monitored from anywhere and anytime. In this study, the system uses a nodemcu esp8266 microcontroller which functions as a device that activates all components, such as the dht11 sensor, ldr sensor, 2 channel relay and led lights. This system uses a telegram application that functions as an application for controlling lights and checking temperature and humidity which is accessed from a smartphone connected to the nodemcu esp8266 microcontroller via a wifi network. The results of the trials carried out on all the features showed the results as expected.

Abstract

Indonesia is one of the most active Twitter users, so Twitter can be used as a medium to analyze e-learning topics. Studying at school is one of the things that have been affected by the current Covid-19 pandemic. On March 4, 2020, UNESCO (United Nations Educational, Scientific and Educational Organization) recommended that schools adopt a distance education system that allows teachers to reach students remotely and limits educational disruption on social networks. This study aims to answer public opinion that focuses on social media Twitter on this online/distance learning policy. Sentiment analysis is conducted to determine whether opinions on an issue have a positive, neutral, or negative trend value and can be used as a benchmark to improve a service. Sentiment analysis using the k-Nearest Neighbor method with Twitter data as much as 7800 tweet data that has been previously processed and achieves the best accuracy value of 53.03% with a comparison of training data and test data of 80:20.
