COVID 19 disease caused by a corona virus called SARSCo V2 (severe acute respiratory syndrome corona virus 2) was first discovered in China, precisely in the city of Wuhan, December 2019. The spread of this virus is very fast, and one of the ways this virus can spread is through objects around. For this reason, users of online shopping applications are not necessarily packages that arrive at the destination address free from the corona virus. To sterilize online shopping packages, they can be sterilized by spraying disinfectant. Spraying disinfectants can be done manually or automatically, automatic spraying being an efficient and practical way to save energy. The manufacture of this automatic disinfectant sprayer uses an Arduino Uno microcontroller as a tool control system, an FC-51 infrared sensor as an object detector, a mini water pump to drain disinfectant, a door lock for the security system, and other components. By using these components and software that supports the running of the tool, the disinfectant spraying tool can work automatically. This tool is box-shaped and has two sides of the door, the first door is for the door to enter the package and the second door is for the homeowner to pick up the package.

Water management in fish farming ponds during the rainy season is very troublesome for cultivators,This is due to rainwater that enters continuously which can cause damage to grass and objects around the pond and can also cause fish to be dragged by the current and stranded out of the aquaculture pond.From the description of the problem, the authors conducted research by designing a system for draining and filling fish farming ponds that work automatically based on rainwater detection.The way this device works is that when the rain sensor detects raindrops, the tool will translate the rainy weather so that the tool will activate the drain pump.When the water level reaches the upper water level sensor, the device instructs the drain pump to drain the water in the aquaculture pond, the drain pump will stop when the level reaches the lower water level sensor. Furthermore, the tool will instruct the filling pump to fill water into the pool and the filling pump will stop when the water level reaches the normal water level sensor. By implementing this system, fish farming farmers can be helped to drain water from aquaculture ponds when heavy rains occur.

Ilmu Pengetahuan dan Teknologi atau biasa kita kenal dengan sebutan IPTEK saat ini sangat menguasai dunia. Hampir semua kegiatan yang dilakukan oleh manusia setiap harinya memerlukan IPTEK. Salah satu pekerjaan yang rutin dilakukan bagi pemelihara ikan hias adalah mengganti air akuarium. Semakin lama air pada akuarium maka semakin kurang kejernihannya dan secara berkala berubah menjadi air yang keruh. Air yang keruh dapat mempengaruhi perkembangan fisik ikan. Permasalahan timbul apabila pemilik ikan lupa ataupun meninggalkan rumah dalam waktu yang cukup lama dan tidak dapat mengganti air akuarium secara rutin. Maka dari itu penulis ingin membuat sebuah sistem yang dapat mengganti air akuarium secara otomatis. Sistem bekerja dengan dua acara. Pertama apabila air pada akuarium sudah mengalami kekeruhan dan mencapai batas yang ditentukan maka air akan diganti. Kedua penulis akan membuat sistem secara otomatis melakukan pergantian air satu kali dalam satu minggu. Setiap pergantian air yang telah dilakukan akan diberitahu kepada pemilik ikan melalui SMS (Short Message Service) bahwasanya air telah selesai diganti. Sensor turbidity bekerja dalam mengecek kekeruhan air dan proses pergantian air berjalan dengan lancar. Pergantian air baru secara otomatis dalam waktu satu kali dalam seminggu berhasil dilakukan. Modul GSM SIM800L mengirim SMS ke Smartphone memberi informasi bahwasanya air telah diganti dengan air baru.

The bell is a device that can make a sound and has a function as a code, a reminder and a communication tool.In general, in most schools, the operation of the school bell is done manually, i.e. there is a picket teacher orschool officer who must always be ready to ring the school bell according to predetermined hours and inteaching and learning activities at school the school guard / picket teacher is busy with the activity of ringing thebell at school during school hours, changing lessons, taking breaks and going home from school which may bemore than five times a day. But officers often forget to ring the school bell at the right time. This negligencecauses the time taken for lessons which causes the effectiveness of teaching and learning activities to be reduced.So it is still less effective in ringing the school bell according to the hours that have been determined manually.This research builds an automatic bell device that can solve these problems which was built using Arduino Nanoand several other devices with the aim of producing an automatic bell device with bluetooth facilities connectedto a smartphone and applying a bluetooth module to the school bell in managing subject schedules, hours, dates,brightness on the P10 running text module, and turn on the speaker automatically
