Abstract

In the computer system study program at Raharja University there are interfacing courses where the material taught is a microcontroller interfacing technique that uses three types of interface protocols on the microcontroller, namely SPI, I2C, and UART interfaces. The learning process at the practical session students must bring their own materials and components that must be arranged before use, in arranging practical materials which is quite a lot especially for some students who do not understand the concept of microcontrollers, this causes the learning process in interfacing subjects to be ineffective and efficient in terms of time and cost to achieve the objectives of interfacing subject learning. From these problems it is necessary to have a learning media in the form of a practical tool or trainer who can support learning and practical activities in interfacing subjects. This study uses prototyping methods, design and observation methods to observe the learning process in interfacing subjects. Thus in this study will produce a microcontroller interface trainer equipped with several supporting components that are interconnected in one circuit board that will be used as a practical tool for students to apply interfacing material to the microcontroller along with the components directly expected by students using this trainer will get a theoretical understanding and application.

Abstract

In economics management is needed periodic data (time series) from production effort in predicting continuation of a situation is action which at one time must be done. For economic or political experts, it seems to be an obligation that must be carried out when they find a situation say just the economic crisis that befell a country with great, to provide predictive reviews about how the impact will be on the continuation of the existence of that country. So from that the aim of this research is to discuss about conceptual and conceptual aspects about periodic data, calculation of straight line trends through free method, half moving average, half average and least number of squares, non linear trend calculation which is trend parabola and exponential trends, calculations for changing trend equations into quarterly and monthly trends, calculations for changing trend equations into average trends, calculating seasonal variation values ​​through simple average methods, ratio to trend, ratio of moving averages and relative berangkai, and calculation of cyclic variation values ​​for annual and quarterly data. The method used during this study took place, namely using a literature study method which functions so that in research, researchers continue to add insight.
