Abstract

This research aims to analyze the financial feasibility and sensitivity of investment in the rejuvenation of smallholder oil palm plantations in Lungmane Village, Kuala Pesisir Subdistrict, Nagan Raya Regency, Aceh Province, amidst the problem of declining Fresh Fruit Bunch (FFB) productivity due to aging trees. The research method used is quantitative analysis with investment criteria of Net Present Value (NPV), Internal Rate of Return (IRR), Net Benefit-Cost Ratio (Net B/C), and Payback Period (PP), as well as sensitivity analysis to changes in FFB prices. The results of the analysis show that the rejuvenation project for smallholder oil palm plantations in Lungmane Village is financially feasible based on positive NPV, IRR, Net B/C, and Payback Period indicators. However, the sensitivity analysis reveals that the project's feasibility is highly influenced by fluctuations in FFB prices, where a price decrease of up to 70% can render the project unfeasible. This study concludes that although the rejuvenation of smallholder oil palm plantations in Lungmane Village has good financial prospects, farmers need to be aware of the risk of declining FFB prices.

Abstract

Employee productivity and workload are closely correlated. Employees are frequently physically and psychologically burdened by high goals and unfavorable working conditions. Industry participants and business actors must be aware of these problems and the steps that can be taken to solve them. In order to help business actors and industry participants solve connected issues, this study attempts to compile a variety of research findings on employees' physical and mental pressures and attempts to overcome them. The Publish or Perish 8 program was used to collect data via meta-analysis. The Google Scholar database was used to compile articles published between 2022 and 2024. Data collecting, data reduction, data presentation, and conclusion-drawing were the phases of the meta-analysis that produced 34 papers. According to the survey, employees' mental workload problems were more common than their physical workload. The issue of employee workload can be resolved by routinely assessing employee workloads to ascertain when hiring more personnel is required, upholding a safe and comfortable workplace, allocating workloads equitably, supplying sufficient personal protective equipment, and paying all employees appropriately
