Food is an essential aspect of the laying hens' cultivation process. The delay of the feeding time and the short amount of food can cause stress to the hens. Furthermore, an excessive amount of food can cause overweight and reduce hens' productivity. This paper provides a method to automate the feeder for laying hens using a device based on microcontroller technology. A tool that can detect chicken behavior when hungry and the temperature of the cage can provide an excellent feeding management system for the breeder. The automatic feeder can see chicken behavior, also the environmental condition around the cage. A specific noise amplitude caused by the hungry hens can trigger the feeder. This feeder also design aims to provide the food in the right amount at the right time. Thus, the breeder can minimize the stress of laying hens, reduce food waste, and keep the hens ideal. Here the system can save the chicken’s food around 13.76% more efficient.

Mengunci pintu merupakan bentuk keamanan dalam sebuah ruangan ataupun gedung. Kelalaian dalam pemeriksaan ruangan dapat berakibat fatal. Penelitian ini bertujuan untuk merancang sistem yang dapat memonitoring keadaan kunci ruangan, apakah ruangan tersebut terkunci atau tidak terkunci dengan menggunakan limit switch sebagai pendeteksi yang telah dipasang pada pintu, jika pintu tidak terkunci maka nilai limit switch bernilai 0 dan jika pintu terkunci maka limit switch bernilai 1. Lalu nilai limit switch dikirim ke server menggunakan modul wifi ESP8266 yang telah terhubung dengan WLAN. Nilai limit switch yang telah terkirim ke server ditampilkan pada smartphone menggunakan aplikasi mobile monitoring kunci pintu. Untuk mengantisipasi pemalsuan kondisi kunci pintu, sistem ini menggunakan 3 indikator untuk menyatakan pintu terkunci yaitu sensor infra merah sebagai penentu pintu terbuka atau tertutup, limit switch 1 dan limit switch 2 sebagai penentu kondisi kunci pintu terkunci atau tidak terkunci. Tingkat kecocokan data yang ditampilkan pada smartphone dengan keadaan yang sebenarnya adalah 100% dengan nilai limit switch bernilai 0 maka pintu tidak terkunci dan limit switch bernilai 1 maka pintu terkunci. Sistem dapat memberikan notifikasi pada saat terjadi perubahan kondisi kunci pintu pada jam malam. Saran untuk penelitian berikutnya sistem dapat melakukan control terhadap pintu, tidak hanya monitoring dan meningkatkan aspek keamanan jaringan wireless.Kata kunci: Kunci Pintu, Android, Limit Switch, Modul wifi ESP8266, Sensor Infra Merah.
