The effect of using lavender pillow spray on improving sleep quality among employees at PT Adhi Persada Beton’s Margorejo Plant

Abstract

Sleep quality among workers remains a significant issue due to workload, occupational stress, and irregular work patterns, which can impact health and productivity. Several studies have shown that lavender aromatherapy can help improve sleep quality through its relaxing effect on the nervous system. This study aims to determine the effect of using lavender pillow spray on improving sleep quality among workers. This study used the pre-experimental method with a one-group pretest-posttest design. Twenty workers at PT Adhi Persada Beton Factory, Margorejo, who experienced mild to moderate sleep disorders, were subjected to a lavender pillow spray applied 2–3 times on their pillows before bed every night for four weeks. The research instrument used was the Pittsburgh Sleep Quality Index (PSQI) to measure sleep quality before and after treatment. Data analysis pillow spray techniques used the Shapiro–Wilk normality test and the Paired t-test for normally distributed data. The results show that the Pretest and posttest data demonstrate a significance value (Sig. 2-tailed) of <0.001 (p <0.05), thus rejecting H0 and accepting H1. The average PSQI score decreased from 10.30 in the Pretest to 6.00 in the posttest, with an average difference of 4.30 points. It can be concluded that the use of lavender pillow spray significantly improves sleep quality among workers at PT Adhi Persada Beton Pabrik Margorejo.
