Abstract

Currently, the consumer goods business in Indonesia is very strict, including for sugar products. Until now, sugar products cannot be fully replaced by other products. The purpose of this study was to determine the effect of customer satisfaction and brand equity on the interest in repurchasing sugar products. This study used a descriptive analytic method using two data sources, namely primary data and secondary data. Primary data obtained by interviewing consumers who consume sugar as many as 60 people. Secondary data obtained from data sourced on the internet, books, journals and other sources deemed relevant. Analysis of the data used in this study is multiple linear regression with the dependent variable repurchase interest and two independent variables, namely customer satisfaction and brand equity. Based on the research results, it is known that the significance value of the F test is 0.000 so that the value is less than 5% alpha. Thus it can be said together that the variables of customer satisfaction and brand equity have an effect on the interest in repurchasing sugar. Based on the results of the t-test, it can be seen that the variable X1 (customer satisfaction) has a significance value of 0.0007 so that the value is less than alpha 0.05 in other words that the variable X1 (customer satisfaction) affects the interest in repurchasing. Variable X2 (brand equity) has a significance value of 0.0317 so that the value is less than alpha 0.05, in other words that the X2 variable (brand equity) affects the dependent variable repurchase interest.

Abstract

Printing is an industry that is constantly evolving and adapting to changing market demands, as well as an increasing focus on sustainability. CV Madyotomo is a company engaged in the printing sector. When excessive incoming orders cause a buildup of print orders of up to 110% of production capacity, this makes employees often have to do overtime. The purpose of this research is to design a PPIC system that is useful for planning and scheduling production so that the entire production process can run smoothly and employees don't have to work overtime too often. PPIC system design can be done using Forecasting with the moving average method and single exponential smoothing. From this research, the results of the forecasting methods used for each level are different. For elementary school level (Elementary School) using the Moving Average method. For junior high school level (junior high school) using the single exponential smoothing method. For SMA level (High School) using the single exponential smoothing method. For MPS (Master Production Schedule) production, the number of daily print orders that must be fulfilled is 78,095. The proposed overtime with MPS in 9 days totals 36 hours. The difference in the frequency of company overtime with overtime according to MPS is as much as 28 hours, this of course will also affect the expenses for the wages paid, of course it will be less than before.

Abstract

Demand forecasting is one of the company's efforts as a basis for making strategic business continuity decisions. The condition of fluctuating demand makes the stock in PT. Margo Mitro Joyo becomes excess or runs out. Based on conditions it is necessary to forecast the demand for LKS. So that stock buildup that occurs at PT.Margo Mitro Joyo can be overcome. From the problems above, the purpose of this research is to find out the number of forecasting requests for Student Worksheets (LKS) in the next period. The analysis was carried out using 2 time series methods , namely weight moving average and single exponential smoothing. So obtained for demand forecasting respectively 971,025.62 and 994,421.12. and then determined by taking into account the smallest error value.

Abstract

Machines play a crucial role in a production process, highlighting the need for maintenance to ensure their proper functioning. The methods employed include Fault Tree Analysis (FTA), Failure Mode and Effect Analysis (FMEA), and distribution determination. The repair times for each CMYK component are as follows: the bearing component requires 93.541 hours or 4 days, Griver needs 163.235 hours or 7 days, the seal requires 195.349 hours or 9 days, the linner pen needs 248.803 hours or 10 days, and the ink tank needs 260.123 hours or 11 days.
