<![CDATA[AbstractWork productivity is an important indicator for assessing workers' ability to complete tasks effectively and efficiently. For railway maintenance workers, productivity is often influenced by the burden of physical activity such as painting, washing, and welding, as well as the adequacy of rest and hydration conditions. Based on a review of previous similar studies, a research gap was found in the form of a lack of studies specifically analyzing the relationship between physical activity, rest, and hydration with productivity in certain work units. This study aims to determine the relationship between physical activity, rest adequacy, and dehydration with work productivity in railway maintenance workers. The study used a quantitative correlational design with a cross-sectional approach. The sample determination in this study was carried out using a non-probability sampling technique with a purposive sampling approach, based on the inclusion criteria that had been determined by the researcher, 25 railway maintenance and care workers were obtained. Data analysis was performed univariately and bivariately using the Chi-Square test. The results showed that 60% of respondents had poor physical activity, 68% had low rest adequacy, and 12% were dehydrated. No significant relationship was found between these three variables and work productivity (p > 0.05). Thus, physical activity, rest, and dehydration are not related to work productivity, which is likely influenced by other factors such as motivation, work environment, and workload.Keywords: physical activity, rest, dehydration, work productivity.AbstrakProduktivitas kerja merupakan indikator penting untuk menilai kemampuan pekerja dalam menyelesaikan tugas secara efektif dan efisien. Pada pekerja perawatan dan pemeliharaan kereta api, produktivitas sering dipengaruhi oleh beban aktivitas fisik seperti pengecatan, pencucian, dan pengelasan, serta kecukupan istirahat dan kondisi hidrasi. Berdasarkan penelusuran terhadap penelitian serupa terdahulu, ditemukan gap penelitian berupa minimnya kajian yang secara khusus menganalisis hubungan antara aktivitas fisik, istirahat, dan hidrasi dengan produktivitas kerja pada unit kerja tertentu. Penelitian ini bertujuan mengetahui hubungan antara aktivitas fisik, kecukupan istirahat, dan dehidrasi dengan produktivitas kerja pada pekerja perawatan dan pemeliharaan kereta api. Penelitian menggunakan desain kuantitatif korelasional dengan pendekatan cross-sectional. Penentuan sampel dalam penelitian ini dilakukan menggunakan teknik non-probability sampling dengan pendekatan purposive sampling, berdasarkan kriteria inklusi yang telah ditetapkan peneliti diperoleh sebanyak 25 pekerja perawatan dan pemeliharaan kereta api. Analisis data ini dilakukan secara univariat dan bivariat dengan menggunakan uji Chi-Square. Hasil dalam penelitian menunjukkan bahwa 60% responden memiliki aktivitas fisik buruk, 68% memiliki kecukupan istirahat rendah, dan 12% mengalami dehidrasi. Tidak ditemukan hubungan signifikan ketiga variabel tersebut dengan produktivitas kerja pekerja (p > 0,05). Maka, aktivitas fisik, istirahat, dan dehidrasi tidak berhubungan dengan produktivitas kerja, yang kemungkinan dipengaruhi faktor lain seperti motivasi, lingkungan kerja, dan beban pekerjaan.Kata kunci: aktivitas fisik, istirahat, dehidrasi, produktivitas kerja.]]>
