Many technologies are constantly evolving to facilitate teaching and learning. The presence system became an obstacle in practicality and recording to a central server in STMIK Mardira Indonesia that has hundreds of students, especially if the presentation is done manually, requiring considerable time and providing opportunities for human error. System Presence Development Lecturer and Student using CodeIgniter Framework-based QR Code using the programming language PHP, JavaScript, jQuery. The method used, namely, observation, interview, literature, and systems development, is used using the model of requirements, analysis, design, implementation, and testing. It can be concluded that the system has been perfected following the schedule of lectures and the system can process data with both faculty and students.

The writing of this paper discusses the process of monitoring strawberry plants implemented in strawberry gardens which will later become a reference to be able to design a tool for monitoring strawberry plants through Internet of Things (IoT) technology. There are several tools used, one of which is Arduino IDE as programming software to connect the Esp 8266 MCU Node, DHT 22 Sensor. Soil moisture Sensor, and other electronic components. Some of these tools are programmed using Eagle Software as a hardware board printing to form a PCB (Printed Circuit Board) or printed circuit board and become an interconnected hardware device. The use of the Bylink Application as its control and monitoring. Empirically and according to several farmers in Ciwidey, Bandung Regency, strawberry is a plant that is susceptible to changes in temperature and climate. With this tool, it is hoped that it will make it easier for farmers to determine soil moisture, identify plants that have not been watered and have not been given anti-pests or vitamins, and that their use can be extended both on a small scale in plantations to large scale that is able to take advantage of several agricultural industries. In addition, this system can be a modern digital technology that is able to reduce the percentage of crop failure due to lack of air or exposure to pests and temperature changes so that growing strawberries is easier and more efficient.
