The government through the Ministry of Education and Culture (Kemendikbud) has made a decision to suspend teaching and learning activities in schools. The learning process that starts face to face directly in the classroom turns into distance learning /brave. However, the government decided to reopen schools in the Covid-19 corona virus green zone for teaching and learning activities for students. The opening of special schools in the green zone will be held in mid-July 2020. School openings must be opened with strict health protocols, no updated potential for new Covid-19 clusters in schools. This is a form of application of the "New Normal" that is being adapted to the people of Indonesia. Indonesian people must consider the existence of this corona virus pandemic with new normalcy, such as using a compilation mask outside the home, always using a hand compass tool and using a loudspeaker and distance measuring device. The purpose of this study was to make an automated hand sanitizer design as an effort to improve the delivery of Covid-19 in schools. Automatic hand sanitizer is useful to facilitate the hand sanitizer liquid out of the bottle, so it is more effective to use and does not run out quickly. This study uses an Arduino Nano microcontroller as the main control, a human hand detection sensor, and a servo motor as an actuator that will activate the automatic bottle. The mouth of the hand sanitizer bottle uses an elastic hose that leads to the part where the cleaning liquid comes out. This research uses the Research and Development (RnD) method. The result of this research is an automatic hand sanitizer with a large size hand sanitizer that can be mounted into a tool with a maximum of 500 ml. This automatic hand sanitizer will automatically release the hand sanitizer fluid which approves the sensor under the user's hand protective device.

Sistem smart home saat ini telah banyak diterapkan dalam kehidupan sehari-hari. Smart home mampu memberikan keamanan dan kenyamanan pada penghuni rumah. Sistem ini bekerja dengan mengontrol beberapa peralatan rumah tangga. Pada umumnya sebagian besar sistem kendali peralatan listrik rumahan masih bersifat manual yaitu dengan menghubungkan peralatan listrik pada stop kontak atau menekan saklar secara langsung. Penerapan sistem kendali manual seringkali membuat pengguna lupa mematikan saklar atau peralatan elektronik lainya saat sedang keluar rumah. Oleh karenanya, pengguna diharuskan untuk mematikan secara manual dengan kembali ke rumah atau terkadang dibiarkan menyala oleh pemilik rumah. Penerapan sistem kendali yang dapat dioperasikan dari jarak jauh diperlukan untuk mengatasi hal ini. Sistem ini mampu membuat pengoperasian dan pemantauan peralatan listrik menjadi lebih efisien. Pada penelitian ini, prototipe sistem smart home dibuat dengan memanfaatkan fitur chat yang tersedia pada Telegram yang dipakai untuk mengontrol relay modul. Sistem bot pada Telegram digunakan sebagai pengirim dan penerima pesan untuk mengontrol relay modul yang terhubung pada peralatan kelistrikan. Metode yang digunakan dalam penelitian ini adalah Research and Development. Sistem dikembangkan menggunakan Modul NodeMCU ESP32 perangkat lunak Micropython. Berdasarkan hasil pengujian yang dilakukan, menunjukkan bahwa hasil uji kelayakan rata-rata keseluruhan adalah 84% yang meliputi aspek desain alat, aspek kinerja alat, aspek kemudahan pengoperasian dan implementasi. Penilaian hasil uji kelayakan diberikan oleh narasumber ahli dibidangnya sehingga menunjukkan bahwa prototipe ini sudah cukup baik dan layak untuk diterapkan pada sebuah rumah. The smart home system is now widely applied in everyday life. Smart home can provide security and comfort to the occupants of the house. This system works by controlling several household appliances. In general, most control systems for home electrical equipment are still manual, namely by connecting electrical equipment to a wall socket or pressing the switch directly. The application of a manual control system often makes users forget to turn off switches or other electronic equipment when leaving the house. Therefore, the user must turn it off manually by returning home, or sometimes it is left on by the homeowner. The application of a control system that can be operated remotely is required to overcome this. This system can make the operation and monitoring of electrical equipment more efficient. In this study, a smart home system prototype was created by utilizing the chat feature available on Telegram, which controls the relay module. The bot system on Telegram is used as a message sender and receiver to control relay modules connected to electrical equipment. The method used in this research is Research and Development. The system was developed using the NodeMCU ESP32 Module and Micropython software. Based on the tests conducted, the overall average due diligence result is 84% , including aspects of tool design, tool performance, and ease of operation and implementation. Expert sources assessed the feasibility test results in their fields to show that this prototype was good enough and feasible to be applied to a house.

Learning Management System (LMS) technology is a web-based technology developed to improve the learning process through proper planning, application and evaluation in educational institutions. The use of LMS in the learning process helps facilitate e-learning because it provides educational material without time or place constraints. SMK Ketintang is a vocational high school under the auspices of the Widya Dharma Surabaya Foundation. SMK Ketintang seeks to implement edu-learning, a Learning Management Systemplatform (LMS)equipped with chat andfeatures teleconference which are used as online learning media in the era of the Covid-19 pandemic. Edu-learning was developed with the aim of being a bridge between teachers and students in organizing and implementing learning. The analysis of the use of edu-learning as anlearning medium online in the Covid-19 pandemic era has 4 (four) indicators, including: (1) ease of use; (2) delivery of information; (3) media attractiveness; (4) media features. The results of this study indicate that the level of effectiveness in using edu-learning reaches 79.5%. So it can be concluded that edu-learning is effectively used as an online learning medium in the era of the Covid-19 pandemic.
