Abstract

PT XYZ is a company that produces furniture products that use the "Make to stock" method to meet consumer demand. In the production process, there is often a buildup of raw materials, one of which is the minifix bolt component, which causes a buildup of raw materials in the warehouse. Therefore, it is necessary to forecast raw materials to predict the amount of raw materials each period. In the forecasting process, you can use the moving average and single ex-ponential smoothing methods. From the calculation results using the POM-QM software, the MAD (Mean Absolute Deviation) value was 13,111.11, MSE (Mean Squared Error) was 261,975,300, MAPE (Mean Absolute Percent Error) was 226,303%. From the software output results, it is known that the smallest MAD, MSE, and MAPE values ​​of the three methods are the moving average method. So this method was chosen to solve problems within the company because the smaller the error that occurs, the smaller the possibility of something bad happening.

Abstract

The pandemic era that occurred in 2020 is a new history in human civilization. The emergence of the pandemic has limited interaction between humans and the surrounding environment. Limited interaction during the pandemic is manifested in the social distancing program, indirectly this program can reduce the sense of social concern, kinship and togetherness between residents. Not only does it have an impact on social welfare, this program will also limit buying and selling activities in markets and local village environments. Thus affecting the level of economic welfare of local communities. The pandemic era that has ended has not been able to restore the economy and health of the affected communities, so various individual and group efforts still need to be made that can increase people's income. Some of the problems above are the background and reasons for choosing Simomulyo Village as our KKN object. Simomulyo village has a very strategic location because it is located in the city center and has a fairly large market. Of course, this condition causes Simomulyo village to receive a significant impact from the pandemic period to the post-pandemic period. To solve existing problems, we and the Simomulyo Village community will work together to maximize the benefits of implementing the waste bank program. The success of this optimization is marked by increased awareness and insight of the village community regarding waste that is ready to be recycled and sold to increase village income. The hope is that, apart from being useful in creating a healthy environment, the waste bank program will also be useful in improving economic and social welfare for the people of Simomulyo Village. This is realized in the form of a waste bank account which is accumulated into cash to ensure the smooth implementation of several village activities.
