Abstract

The East Jakarta area has many residential areas, from the lower to the upper classes, and residential areas for businesses such as malls, markets, mini supermarkets, and protected tourist attractions, for example, the urban forest area. East Jakarta City is currently trying to maintain the excellent air quality in the area. Currently, the local government's prevention of poor air quality and air quality checks in East Jakarta is not going well because the budget requires a large amount of money. Therefore, a tool was made to detect air quality. The tool built in this study is based on the MQ-135, DHT-11, NodeMCU 8266 microcontroller, and Blynk application using the C++ language on the Arduino application. This tool is expected to provide information to users regarding the level of air quality in the area. This tool will automatically connect to an available wifi network. An air quality notification will immediately appear, along with the temperature and humidity values displayed on the smartphone. The tool made is expected to help view air quality. All information obtained can be helpful for follow-up by the government and the community to maintain the beauty and good air quality in the area

Abstract

River water that overflows or is at an uncontrolled height can cause flooding and environmental damage. Therefore, the development of a river water level detector that can provide early warning is very important. In this research, we propose a river water level detector using ultrasonic sensor with sound output based on Arduino Uno microcontroller. This device is designed to measure the level of river water by utilizing the principle of ultrasonic wave reflection. The ultrasonic sensor is installed above the river and sends ultrasonic waves to the water surface. The waves are then reflected back to the sensor after reaching the water surface. The travel time of the reflected wave is used to calculate the distance between the sensor and the river water surface.The Arduino Uno microcontroller is used to process the distance data obtained from the ultrasonic sensor. When the water level exceeds the specified limit, the microcontroller will generate a sound output as a warning. A speaker is connected to the microcontroller and will emit different sounds depending on the water level.This tool has advantages in terms of accuracy and responsiveness. By using ultrasonic sensors, measurements can be taken in real-time and provide water level information with high precision. The voice output also allows the information to be delivered directly and effectively to the user. The test results show that this river water level detection device can work well and provide early warning when the water level exceeds the specified limit. The success of this tool is expected to help in flood risk management and environmental conservation.

Abstract

The Putra Elektronik Store is a commercial establishment that sells various electronic goods, including mobile phones, desktop computers, and laptops, among other products. The procedure for conducting transactions, which has been ongoing until now, is still done manually. The author suggests developing an online sales platform based on this information. The system design uses UML in addition to the programming languages PHP and Laravel. In addition, a tool for collecting customer reviews has also been developed. The purpose of this feature is to determine whether consumers' feelings regarding the things being offered are favorable or unfavorable by employing the navel Bayes algorithm and weighting tf (term frequency) and probability..
