Abstract

Riau Province is one of the regions known for its plantation products, especially in the oil palm sector, so that Riau Province and regional districts focus on oil palm plants as the main commodity of plantations in Riau. Based on data from the Central Bureau of Statistics (BPS) of Riau Province, the annual production of oil palm plantations, especially smallholder plantations in Riau province has always increased. So is the demand for world CPO. But sometimes the selling price of oil palm fresh fruit bunches (FFB) for smallholder plantations always changes due to many influential factors. With the Artificial Neural Network approach, the Backpropagation algorithm we conduct training and testing of the time series variables that affect the data, namely data on the area of oil palm plantations in Riau Province; Total palm oil production in Riau Province; Palm Oil Productivity in Riau Province; Palm Oil Exports in Riau Province and Average World CPO Prices. Then price predictions will be made in the future. Based on the results of the training and testing, the best Artificial Neural Network (ANN) architecture model was obtained with 9 input layers, 5 hidden layers and 1 output layer. The output of RMSE 0000699 error value and accuracy percentage is 99.97% so that it can make price predictions according to the given target value.

Abstract

PT. Andhana Kirana Yasa is a company engaged in car accessories installation services. The speed in the production process and the quality of products produced become the main value to compete with competitors. But to achieve the desired quality there are still problems that are experienced, first reject the unit of production and second, there is a cripple unit (no part), which is the unit in the production process. Still, the stock parts are exhausted in the warehouse so that accessories cannot be installed. The existing problems if not handled quickly and precisely cause a decrease in productivity. The installation service company has been given a maximum target lead time of 1 unit (car) for 3 hours. To overcome this problem, a monitoring application system/program is needed, which monitors the unit's production conditions directly so that when an obstacle occurs, it can be effectively dealt with. This application program is created using the waterfall method, which has the manufacturing stages starting from Requirement Analysis, System Design, Implementation, Integration and Testing, Operation and Maintenance. The programming languages used are HTML, PHP and JavaScript, MySQL as a database, and Sublime Text Editor as an editor. The purpose of making the application program is to monitor the unit production directly against problems that occur and produce data that is used to evaluate employee performance.

Abstract

Cold Chamber is a small cold room in a cooling system as a storage place for cold air before the air is flowed to the object to be cooled. A cooling system will be greatly influenced by temperature lowering sources. To be able to provide optimal results in a cooling system, it requires a cold chamber whose temperature can be controlled automatically. To be able to control the temperature, a tool is needed. So that the tool can control the temperature, the tool needs a sensor that can read the temperature in the cold chamber, namely DS18B20. This sensor works by reading the temperature of the environment and then sending it to the microcontroller. To control the temperature, the microcontroller will send commands to the fan which functions as a sender of cold air to the cold chamber, and a pump which functions to drain water on the hot side of the cooling element. The cold air source in this tool comes from Peltier TEC1-12706. The reading result and the desired temperature setting will be displayed on the LCD. If the actual temperature is greater than the desired temperature, the fan will blow more cold air into the cold chamber and the pump will flow water faster. If the actual temperature is less than the desired temperature, the fan will stop blowing and the pump will slow down the flow of water. With this tool, it will be easier to adjust the temperature in a cooling system.
