Broiler Chicken Feed System is a tool that is implemented using microcontroller technology. The focus of technology in industry 4.0 is that all devices can be controlled and monitored remotely, as long as they are connected to a network. In accordance with this vision, this technology makes it easier for farmers to feed chickens that were originally still using manual labor, then made automatically by implementing microcontroller technology consisting of SIM800L, Arduino, servo motors, and ultrasonic sensors. By using two ultrasonic sensors that are placed to enter orders and provide information about the stock of chicken feed this technology can work well. The focus of this technology is that it can be used for remote monitoring. Not only that, this technology can also send notifications to the farmer's smartphone to show the condition of the chicken feed stock that is still available. By applying this technology, chicken farmers can combine and feed their chickens from anywhere.

Makin jaya shop is one of the shop that engaged in selling cloth and equipment   of school. But currently still using manual method in transactions and management of the data. So it need a system to efficien all of the performance by controllong stock items by forecasting   stocks that must be met. The trend moment method is able to forecast to estimate the amount of stock that must be met. The implementation of Trend Moment method on application  can predict for uniform white shirt items sales in the month and year desired by users by using two-year data on the Trend Moment method even though the maximum level of accuracy is 85.18%. The long term impact of the use of forecasting for goods stock control can increase sales profits and trust of customers.
