Abstract

This research discusses the comparative analysis of linear regression and exponential smoothing methods in forecasting demand for Pertalite products at PT Pertamina Patra Niaga Regional North Sumatra, especially the Medan Retail Sales Area. This research aims to find out the most accurate forecasting method in predicting demand for Pertalite in the Medan Retail Sales Area. Historical demand data from the period January 2023 to June 2024 is used as the basis for the research. The research results show that the linear regression method has a better level of forecasting accuracy than the exponential smoothing method based on error calculations. The linear regression method produces a Mean Absolute Deviation (MAD) value of 3,157,216, a Mean Square Error (MSE) of 1,571,886,522, and a Mean Absolute Percent Error (MAPE) of 2.97%. Meanwhile, the exponential smoothing method with alpha values of 0.1, 0.5, and 0.9 produces MAD values of 3,244,072, 3,746,722 and 4,796,245 respectively, MSE values of 2,010,507,177, 2,580,704,082 and 3,344,564,362, and MAPE values of 3.08%, 3.54% and 4.52%. Therefore, it is concluded that the linear regression method is the most appropriate to use in forecasting demand for Pertalite in the Medan Retail Sales Area because it has the smallest error value. It is hoped that this research can help PT Pertamina Patra Niaga in making strategic decisions regarding inventory management and fuel distribution more efficiently.

Abstract

This article discusses evaluating customer priorities in freight forwarding companies using the Simple Multi-Attribute Rating Technique (SMART). SMART techniques can be used to evaluate consumer priorities within an organisation, taking into account factors such as delivery timeliness, the safety and integrity of goods, communication and response, pricing, and flexibility in service options. This study seeks to identify and assess the service features that consumers consider most significant and offer recommendations for service improvement. The results revealed that the A2 alternative was rated first, A1 second, and A6 third, with scores of 0.547, 0.257, and 0.185667, respectively, underscoring a preference for traits with greater benefits. Customers prioritise the safety and integrity of the goods, achieving a maximum score of 76, indicating a significant assessment of the condition of the goods received. This is especially relevant in the halal ecosystem, where compliance with halal standards is essential across sectors such as food, pharmaceuticals, and cosmetics. The transportation and management of halal-certified products must comply with halal certification standards, which quickly impacts consumer choice in the freight forwarding industry. Damage or loss of goods during delivery is a significant issue that the service provider must address. Investigations show that customers prioritise reliability, security, integrity of goods, speed of delivery, and effective communication, which is further strengthened by the increasing demand for halal-compliant services.
