Analisis Beban Kerja Mental pada Guru SD Yayasan Pendidikan Harapan 3 Medan Menggunakan Metode NASA-TLX

Abstract

This study examines the high mental workload experienced by teachers at SD Harapan 3 Medan and underscores the importance of maintaining educators’ mental health to support teaching quality. It aims to measure variations in teachers’ mental workload across teaching days, Monday, Friday, and Saturday, and to identify differences in workload patterns according to teacher age groups (young adult, adult, and pre senior). Data were collected via the NASA TLX questionnaire, which assesses six indicators: mental demand, physical demand, temporal demand, performance, effort, and frustration. Indicators were first weighted and then rated on a 0–100 scale; product scores and the average Weighted Workload Level (WWL) were subsequently calculated. Analysis revealed that Monday recorded the highest average mental workload (82.1), followed by Saturday (80.9) and Friday (80.3), with mental demand as the dominant factor on all days. By age category, pre senior teachers were most burdened by physical demand and time pressure, adult teachers by mental demand and time pressure, and young adult teachers by mental demand and performance requirements. In conclusion, although all teacher groups experienced a high mental workload, the dominant contributing factors varied by day and age. This study recommends optimizing schedule planning and reducing the frequency of classroom changes to alleviate teachers’ mental workload.
