Abstract

The lamp is a lighting tool that is very widely used in everyday life as a means of lighting. The lamp will work or can be used if the lamp is given a power source or voltage. In general, to turn on the lights, we still do it manually, namely pressing the switch as a current or voltage connector for the lamp. However, if done manually it can be an obstacle for those who are busy, so that turning on the lights in their room has difficulty or takes time. Based on the problems above, here the author will design a plate that can be used to make it easier to turn on or control the lights in a room or house. In this case, the author uses a BlueSPP application on the PlayStore using Android Bluetooth and the Arduino interface uses Bluetooth HC-05. This equipment has a working system that is easy for anyone to use, control will be carried out by sending messages from the BlueSPP application via Bluetooth between the Android smartphone and the Arduino microcontroller. When the user sends a message from the BlueSPP Application, the Bluetooth HC-05 will receive commands from the application and forward it to Arduino as a data processor for the message to be instructed to relay whether to turn it on or off. In testing this equipment can work with a maximum range of 15 meters without any obstacles and a maximum work of about 8 meters when there are obstacles.

Abstract

Limited air resources and inefficient irrigation practices are major challenges for agricultural management in dryland areas, such as in East Nusa Tenggara Province. Manual irrigation systems result in unmeasured air usage, uneven air distribution, and increased farmer workloads. Therefore, the implementation of efficient and adaptive irrigation technology to environmental conditions is necessary. This Community Service activity aims to implement an Internet of Things (IoT)-based automatic irrigation control system using the drip method on the agricultural land of a farmer group in Oeltuah Village, Taebenu District, Kupang Regency. The implementation method includes an initial survey, system design, device construction and installation, system testing, and mentoring for farmer partners. The developed system uses a soil moisture sensor, an ESP32 microcontroller, a Real-Time Clock (RTC) module, a water pump, and a drip irrigation pipe network connected to an internet-based monitoring system. The results of the activity show that the automatic irrigation system operates well and is able to increase the efficiency of air use and regulate watering schedules more consistently. With the support of ongoing mentoring, this technology has the potential to increase agricultural productivity and the development of smart agriculture models (smart farming) in dryland areas.
