Liquified Petroleum Gas (LPG) merupakan kebutuhan rumah tangga yang saat ini paling banyak dimanfaatkan oleh masyarakat sebagai bahan bakar selain minyak bumi. Apabila gas LPG mengalami kebocoran tidak dapat dideteksi apabila jarak indra penciuman cukup jauh, sehingga diperlukan sebuah sistem untuk mendeteksi terjadinya kebocoran gas yang dapat menyebabkan kebakaran melalui jarak jauh. Penelitian ini bertujuan untuk mendeteksi terjadinya kebocoran gas dan kebakaran yang dapat memberikan informasi kepada pengguna melalui pesan ke aplikasi Telegram. Metode penelitian yang digunakan adalah prototype. Hasil penelitian ini mampu merancang sistem untuk mendeteksi adanya kebocoran gas dan kebakaran menggunakan NodeMCU ESP8266 berbasis IoT, dimana alat ini dapat memberikan tanda peringatan berupa nyala lampu LED, suara alarm dari buzzer, menampilkan keadaan melalui LCD, dan menerima notifikasi peringatan ke Telegram.

Memeliahara kucing merupakan hal yang sangat digemari, namun tidaklah mudah untuk memonitoring penyimpanan pakan dan  minum kucing secara real-time, dalam hal ini para pemelihara memerlukan sistem  yang dapat memonitoring kondisi pakan dan minum kucing mereka tanpa harus berada dirumah. Pada penelitian ini menggunakan Metode Prototype untuk mengembangkan sistem. Hasil penelitian menunjukkan bahwa sistem ini bekerja secara otomatis menggunakan RTC untuk penjadwalan waktu pemberian pakan, Sensor Load Cell sebagai alat untuk menimbang berat pakan yang akan dibaca oleh servo untuk menarik tali pintu penampung pakan dan Sensor Water Level untuk mengukur  ketinggian air. Kemudian data pada kedua sensor tersebut akan di tampilkan pada aplikasi telegram untuk mengetahui kondisi dari wadah pakan dan minum kucing.

In addition, sometimes there is a misunderstanding between attendance officers and teachers and employees regarding remuneration at the end of the month.
In solving this payroll problem, the writer uses the Research and Development (R & D) method, while making applications can use high-level programming languages ??such as Microsoft Visual Basic Ver 6.0. and SQL Server 2000 for data base management.
Payroll applications are needed to simplify transactions and reporting on a monthly basis. With the use of this new payroll system software, it is hoped that it can produce quality information, improve service to employees and can assist in the decision-making process
