In today’s increasingly competitive business environment, companies are required to optimize the potential of human resources as a strategic asset. The rapid development of technology, dynamic market conditions, and high employee mobility drive organizations to adopt effective strategies in managing knowledge, employee engagement, and talent. Many companies face challenges such as the loss of competencies due to weak knowledge sharing and low employee engagement, which often lead to high turnover. This condition highlights that knowledge management, employee engagement, and talent management are critical factors in enhancing employee performance. This study aims to analyze the influence of knowledge management and employee engagement on employee performance with talent management as a mediating variable at PT Bank Sumut Head Office Medan. The research employed an associative design with a quantitative approach. Data were collected through questionnaires distributed to 83 respondents selected using purposive sampling from a population of 473 employees working across 18 divisions. The sample criteria included employyees who had worked for at least one year at the Bank Sumut Head Office. Data analysis was conducted using the Partial Least Squares Structural Equation Modeling (PLS-SEM) method. The results indicate that knowledge management and employee engagement have a significant effect on employee performance, both directly and indirectly, through talent management as a mediating variable. These findings suggest that the integrated implementation of knowledge management, employee engagement, and talent management can drive improvements in employee performance.

Azhari Alim Bahri — 2025-09-30

In a company, inventory processing is very important. For this reason, it is necessary to control inventory in order to minimize costs for the benefit of the company. In this study, the authors use the DES method which aims to forecast palm oil demand for 2020 and the Probabilistic EOQ method which can minimize the cost of palm oil inventory at PT. Nusantara IV Medan Plantation. The effectiveness of the Double Exponential Smoothing Method is seen from the minimum MAPE value of 0.29541 which is at an alpha of 0.8. Based on the calculations and data processing carried out, the results of forecasting the demand for palm oil in 2020 were obtained at 483,699,862 Kg with an average demand of 48,369,986 Kg. Based on the Probabilistic EOQ method, the optimal number of orders for palm oil is 8,840,057,829 Kg with an order frequency of 55 times/year with an ROP of 994,798,8395 Kg and the total cost of palm oil inventory is Rp. 79,551,503,603.

Forecasting Rice Production for Strategic Decision Making in Agribusiness Management: Aplication of Brown’s Double Exponential Smoothing in Batubara District

Ahmad Riyansyah — 2025-09-30

An assessment of what will occur in the future is called a forecast. For Indonesians, rice is a staple food, and because of its most crucial role, forecasting is required to satisfy community demands. For that, we require an indicator that can use Brown's double exponential smoothing method to illustrate the rise and fall in Batu Bara District's rice production in 2021. The time series approach, which employs historical data to forecast future events, includes Brown's double exponential smoothing method. Using the parameter α, the data demonstrates a trend. The value that yields the least Mean Square Error (MSE) is the ideal parameter value. The data processing results indicate that the parameter α = 0,1 has an MSE of 362.579.150,59. The volume of rice output in 2021 is predicted to be 118.082,84 tons using the forecasting equation F_(t+m) = 117.773,25+309,5m.
