Supply chain management is very important for a company because it will affect supply performance in the company. Doing business in this era has many challenges that must be faced, especially in the Muslim clothing business. The way to stabilize the demand diagram of the Muslim clothing business, retailers are required to manage the supply chain so that they can meet the total demand. The object of this research is Rabbani Cirebon which was obtained from a literature study published in a journal entitled "Trend of Muslim Lifestyle Changes" from Banjarmasin State Polytechnic. The journal has sales data based on product types from monthly in 2016. From this data will be processed and analyzed using data analysis techniques. This data analysis technique uses time series forecasting data analysis techniques. From this time series method, this research uses moving average and linear regression. After modeling the data, the forecast error is measured using MAD, MAPE, RMSE, and MSE. The overall MSE results were 103731.8 and RMSE 322.0743. The benefit of demand forecasting is to reduce the Bullwhip Effect, plan future resources, for example, such as stock management, place control, product distribution, and demand for raw materials so as to make the right decisions. The results showed that the linear regression method has better forecasting than the moving average because linear regression has a smaller error rate than the moving average. But even so, the error rate of this study is still very large, so it is necessary to do more research to minimize the error rate.

Abstract:The purpose of study is to determine whether there is a positive and significant effect of humanistic approach on learning motivation of class XI students of SMA Negeri 3 Tarutung during Covid-19 pandemic. This research is quantitative descriptive by using descriptive statistic method. The population is 143 students of class XI and the sample of 25%, namely 36 students were taken randomly. A closed questionnaire was used as the instrument for the data collection. The data processing and analysis techniques used simple linear regression method with t-test. The regression equation was Y = 2.5 + 0.21 X + e. The value of X was positive value, it indicated that the better humanistic approach is applied, the more student motivation will be. Based on the data analysis, it was known that the significance value of the humanistic approach variable was 0.047. The results show that the significance value (0.047) is smaller than the value of 0.050 (α). Therefore, it is concluded that H0 is rejected and Ha is accepted. It means that the humanistic approach has a positive and significant effect on students’ learning motivation. Abstrak: Tujuan penelitian ini untuk mengetahui ada tidaknya pengaruh yang positif dan signifikan pendekatan humanistik oleh guru terhadap motivasi belajar siswa kelas XI SMA Negeri 3 Tarutung pada masa pandemi Covid-19. Penelitianini deskriptif kuantitatif dengan menggunakan metode statistik deskriptif. Populasi 143 siswa kelas XI  dan sampel 25 % yaitu 36 orang diambil secara random.Teknik pengumpulan data dengan angket tertutup. Teknik pengolahan dan analisis data menggunakan metode regresi linier sederhana dengan uji-t. Persamaan regresi yaitu Y = 2,5 + 0,21 X + e. Nilai X adalah nilai positif, ini menunjukkan bahwa semakin baik pendekatan humanistik dilakukanguru akan mengakibatkan motivasi belajar siswa semakin meningkat.Dari hasil analisis diketahui bahwa nilai signifikansi variabel pendekatan humanistik oleh guru adalah sebesar 0,047. Karena nilai signifikansi 0,047 lebih kecil daripada nilai 0,050 (α) maka disimpulkan bahwa H0 ditolak dan Ha diterima.

Purpose – The purpose of this paper is to test the effectiveness of fuzzy time series (FTS) forecasting system in a supply chain experiencing disruptions and also to examine the changes in performance as the authors move across different tiers. Design/methodology/approach – A discrete event simulation based on the popular beer game model is used for these tests. A popular ordering management system is used to emulate the behavior of the system when the game is played with human players. Findings – FTS is tested against some other well-known forecasting systems and it proves to be the best of the lot. It is also shown that it is better to go for higher order FTS for higher tiers, to match auto regressive integrated moving average. Research limitations/implications – This study fills an important research gap by proving that FTS forecasting system is the best for a supply chain during disruption scenarios. This is important because the forecasting performance deteriorates significantly and the effect is more pronounced in the upstream tiers because of bullwhip effect. Practical implications – Having a system which works best in all scenarios and also across the tiers in a chain simplifies things for the practitioners. The costs related to acquiring and training comes down significantly. Originality/value – This study contributes by suggesting a forecasting system which works best for all the tiers and also for every scenario tested and simultaneously significantly improves on the previous studies available in this area.

Orca is a company that run in the field of handicrafts, mainly craft bracelet. In this era of tight competition this time, Orca needs a competitive advantage to survive in this industry. To have a competitive advantage, companies must have a good supply chain management as well. Unfortunately, Orca has obstacles in the inventory is one of the Drivers of suplly chain management. Inventories at Orca often occurs over load, causing storage costs become swollen or a vacancy occurs so that the company's stock experienced a loss of income potential. The aim of this study was to determine the best forecasting method to forecast the demand for raw materials from ORCA thus making optimum inventory and gain a competitive advantage. This research is a quantitative descriptive research. Quantitative data analysis was performed to predict the demand for raw materials ORCA using time series forecasting methods. Historical data demand and supply ORCA processed using Microsoft Excel and Minitab 17. The calculation of the error rate used is the method of MAD, MSE and MAPE. Based on the results of data analysis, forecasting method best known is the method of Quadratic Trend Model. This method was chosen because compared to other methods or the error rate to its lowest error, MAPE of 103, amounting to MAD 370, and MSD amounted to 205.095.

Main Factors

In today’s world, all enterprises in a supply chain are attempting to increase both their and the supply chain’s efficiency and effectiveness. Therefore, identification and consideration of factors that prevent enterprises to attain their expected/desired levels of effectiveness are very important. Since bullwhip effect is one of these main factors, being aware of its reasons help enterprises decrease the severity of bullwhip effect by opting proper decisions. Now that forecasting method is one of the most important factors in increasing or decreasing the bullwhip effect, this chapter considers and compares the effects of various forecasting methods on the bullwhip effect. In fact, in this chapter, the effects of various forecasting methods, such as Moving Average, Exponential Smoothing, and Regression, in terms of their associated bullwhip effect, in a four echelon supply chain- including retailer, wholesaler, manufacturer, and supplier- are considered. Then, the bullwhip effect measure is utilized to compare the ineffectiveness of various forecasting methods. Owing to this, the authors generate two sets of demands in the two cases where the demand is constant (no trend) and has an increasing trend, respectively. Then, the chapter ranks the forecasting methods in these two cases and utilizes a statistical method to ascertain the significance of differences among the effects of various methods.
