Sebagian besar Panti Asuhan di Indonesia memiliki kebun pribadi untuk dimanfaatkan sebagai bahan masakan internal Panti Asuhan dan masih melakukan perawatan dan pemeliharaan tanaman secara konvensional. Mikrokontroler arduino UNO dan sensor kelembaban tanah dinilai mampu membantu pekerjaan perawatan kebun dalam mengatur kadar air tanah. Oleh karena itu akan dilakukan pengabdian pada Panti Asuhan Al-Husna Kabupaten malang yang memiliki kebun sayur yang lumayan luas sehingga pengabdian ini bisa membantu perawatan. Pengabdian ini ditujukan untuk Mengetahui cara pemanfaatan mikrokontroler arduino dalam meningkatkan pertumbuhan kebun cabai. Mengetahui pengaruh beberapa level kadar air yang berbeda terhadap pertumbuhan tanaman cabai yang diatur secara presisi menggunakan mikrokontroler Arduino. Menentukan kadar air yang optimal pada pertumbuhan cabai. Diharapkan dari pengabdian ini bisa membantu kelayakan dan kualitas makanan pada Panti Asuhan Al-Husna Malang Kabupaten Malang.

Advances in automation technology in industries that run very fast have spurred every educational institution to be able to keep up. Every SMK is no exception, which is tasked with preparing and producing students to be able to compete in the world of work. One of the automation technologies is PLC and SCADA which are widely used in the industrial world, for this reason, it is necessary for Muhammadiyah Gresik University students, especially the Electrical Engineering study program, to share knowledge about one of the PLCs and SCADA by using Outseal as PLC and Haiwell as SCADA at SMKN Singosari, Malang in the form of community service activities. By providing training on the basics of PLC and SCADA using Outseal software as a PLC which is uploaded to Arduino and Haiwell as an HMI for SMK students in understanding the basics of PLC which is then followed by simulating cases that often occur in the industry. The results of the student response were very positive giving an assessment of more than 90% and wanting a similar training with a different theme.

The research method used in this study is the research and development method or also called Research and Development. The research design that will be developed in this study uses the development model presented by Borgan Gall. The product produced in this study is an Arduino Nano-Based Distance Measuring Tool with a Display on the LCD on the Flat Side Room Building Material for Class VIII at SMP Negeri 5 Sepauk. The test subjects of this study included two subjects. The first subject is the validator and the second is class VIII students of SMP Negeri 5 Sepauk. The analysis technique used is to determine the effectiveness, practicality, and validity. The percentage of effectiveness from the average of the two analyzes obtained a percentage value of 94.06% with Very Effective criteria used in learning mathematics. The results of the combined teacher and student response questionnaires - the average percentage obtained was 89.55% with very practical criteria. The combined results of the average percentage obtained from the percentage of experts and the results of the measurement trials obtained a percentage of 76,36% with very valid criteria.
