Kebisingan merupakan salah satu risiko fisik yang terkait erat dengan operasi industri. Hasil survei pendahuluan di lokasi penelitian menggambarkan pekerja harus berteriak atau berbicara keras agar pekerja lain dapat mendengarnya. Hasil pengukuran kebisingan pada survei pendahuluan sebesar 84,72 dBA pada titik 1, 90,3 dBA pada titik 2 dan 89,6 dBA pada titik 3, serta ditemukan dua pekerja mengalami kelelahan kerja. Penelitian ini bertujuan untuk mengetahui hubungan intensitas suara dengan kelelahan mental pekerja pemotong batu alam Home Industry tahun 2024. Penelitian ini merupakan penelitian analitik menggunakan desain cross sectional dengan variabel bebas intensitas suara dan variabel terikat kelelahan mental. Populasi dalam penelitian adalah seluruh pekerja yang berjumlah 80 pekerja dengan sampel berjumlah 35 pekerja yang berinteraksi langsung dengan mesin pemotongan di bagian pemotongan. Analisis data dilakukan secara bivariat (uji chi-square dengan α. = 0.05). Hasil uji statistik intensitas suara rata-rata 107.731 dBA dengan standar deviasi 3.1740 dBA. Intensitas suara terendah 102.7 dBA dan intensitas suara tertinggi 114.3 dBA. Dua belas pekerja mengalami kelelahan mental dan dua puluh tiga pekerja tidak mengalami kelelahan mental. Tidak ada hubungan intensitas suara dengan kelelahan mental. Pertimbangkan rotasi pekerjaan agar pekerja tidak terpapar kebisingan secara terus-menerus.

Abstract

Introduction: In Indonesia, the average dengue cases are 121,191 each year with a Case Fatality Rate (CFR) of 0.69%. Mosquito control with common chemical methods will negatively impact the environment and human health and can cause mosquitoes to develop resistance. Environmentally-friendly replacement chemicals derived from plants such as citronella contains 16.27% citronella and 19.88% geraniol. In addition, lavender plants also contain 35% alcohol comprising linalool and geraniol as well as other chemicals such as borneol. Furthermore, 8-20% of camphor and borneol in rosemary can also be a natural mosquito repellent ingredient. Methods: This study is a True Experiment with The Posttest-Only Controlled Group Design. The number of Aedes aegypti mosquitoes used for each treatment was 20. The study subjects were divided into 4 groups comprising 0.4 ppm of citronella, lavender, and rosemary essential oils and aquades as control. Replication was carried out 3 times and observations were conducted for 20 minutes. Results and Discussion: The Anova Factorial test resulted in a p-value of ≤ 0.05. In addition, there was a significant difference in the number of Aedes aegypti mosquitoes expelled from humidifier vapor. Furthermore, the Least Significant Difference (LSD) test showed that citronella essential oil was most effective in repelling mosquitoes because it has a p-value of ≤ 0.05 and largest average difference between other essential oils. Conclusion: Essential oils from citronella are most effective and stable for 30 seconds to 20 minutes to repel mosquitoes compared to lavender and rosemary essential oils
