Abstract

Distribution efficiency in the cement industry is a key factor that influences the sustainability of operations and company competitiveness. One critical aspect is managing distribution cycle time, which involves the process of loading cement from the factory to the ship. This research was conducted at PT. X to analyze cycle time optimization in cement distribution using discrete simulation methods. This research is the importance of reducing cycle time to avoid delivery delays which can result in fines (demurrage) and operational losses. The simulation results show that using one compressor requires an average of 108 minutes per trip, so that to complete 5 trips per trailer it takes a total of around 11.3 hours. While this duration still allows for the delivery target of 1,800 tons in 12 hours to be achieved, this approach leaves little room to overcome potential operational obstacles, such as technical glitches or delays, thereby increasing the risk of late fines. As a solution, the addition of one compressor has been proven to reduce loading time to 54 minutes per trip, reducing the total time for 5 trips to only 6.8 hours, providing significant efficiency and increasing operational reliability. This research concludes that adding a compressor can significantly reduce the risk of delays, increase efficiency and support the sustainability of company operations.

Abstract

In the era of globalization, industry and trade in Indonesia are experiencing fierce competition. Technological advances require qualified human resources from formal or non-formal educational institutions with supporting facilities. This research focuses mainly on solving the problem of the type A towel production process which often occurs in the accumulation of goods in the Finishing Warehouse using the Moving Average and Single Exponential Smoothing methods. Due to the current changing market demand, the results of data processing carried out using POM-QM software show that the forecasting method with the Single Exponential Smoothing approach has the lowest Mean Absolute Percentage Error (MAPE) value among other methods, which is 32.637%, so this method was chosen in solving problems in the company because the smaller the error the smaller the possibility of bad things that will happen.

Abstract

The number of restaurant and franchise companies in Indonesia makes people more selective in choosing products that suit what they want. In this case, companies are required to be careful in developing marketing strategies in order to spur competitiveness to win market competition. Therefore, this research tries to find out the influence of product quality, service quality, and sales promotion on purchasing decisions that have an impact on consumer loyalty and strategies to improve Dunkin’ consumer purchasing decisions. The research’s methodology is the Structural Equation Modeling (SEM) method and SWOT analysis with a sample size of 100 responders. The outcomes of this research show that product quality has a positive and significant effect on purchasing decisions, service quality cannot be proven because it is excluded from the research model, sales promotion has a negative and insignificant effect on purchasing decisions, and purchasing decisions have a positive and significant effect on consumer loyalty. The simultaneous equation obtained is Y1 = 0.367 X1 + (-0.024) X3 + Z3 and Y2 = 0.117 X1 + (-0.008) X3 + Z4. The strategy obtained from the SWOT analysis outcomes and can be applied by Dunkin’ is to implement the W-O strategy which consists of: (1) Dunkin’ can conduct market research to find the right target market and adjust their sales promotion strategy to the preferences of that target market; (2) Dunkin’ can take advantage of technology and digitalization to increase customer convenience and strengthen brand engagement.
