Faktor-faktor yang Berhubungan dengan Produktivitas Kerja Karyawan PT United Tractors Tbk Site Batukajang

Abstract

Produktivitas kerja merupakan indikator penting dalam menilai efektivitas tenaga kerja, khususnya pada industri alat berat yang menuntut kesiapan fisik dan mental. Penelitian ini bertujuan menganalisis hubungan status gizi, pola konsumsi, kualitas tidur, dan aktivitas fisik dengan produktivitas kerja karyawan PT United Tractors Tbk Site Batukajang. Penelitian menggunakan desain cross-sectional pada 25 karyawan Departemen Service. Produktivitas kerja diukur berdasarkan productive man hour, status gizi menggunakan Indeks Massa Tubuh (IMT), pola konsumsi menggunakan Semi-Quantitative Food Frequency Questionnaire (SQ-FFQ), kualitas tidur menggunakan Pittsburgh Sleep Quality Index (PSQI), dan aktivitas fisik menggunakan Global Physical Activity Questionnaire (GPAQ). Analisis dilakukan menggunakan uji korelasi Spearman dan regresi logistik ordinal. Hasil penelitian menunjukkan prevalensi gizi lebih mencapai 72,0%, konsumsi buah dan sayuran masih rendah, sebagian besar subjek memiliki kualitas tidur baik (84,0%) dan aktivitas fisik kategori sedang, serta 48,0% subjek memiliki produktivitas kerja kategori A. Analisis statistik menunjukkan bahwa status gizi (p=0,339), tingkat kecukupan energi (p=0,628), protein (p=0,877), lemak (p=0,777), karbohidrat (p=0,675), dan aktivitas fisik (p=0,788) tidak berhubungan signifikan dengan produktivitas kerja. Sebaliknya, kualitas tidur berhubungan signifikan dengan produktivitas kerja (p=0,025; r=0,448). Peningkatan kualitas tidur melalui pengelolaan waktu istirahat dan promosi kesehatan di tempat kerja berpotensi mendukung produktivitas karyawan.

Work productivity is an important indicator of workforce effectiveness, particularly in the heavy equipment industry, where optimal physical and mental conditions are essential. This study aimed to analyze the relationships between nutritional status, dietary patterns, sleep quality, physical activity, and work productivity among employees of PT United Tractors Tbk Site Batukajang. A cross-sectional study was conducted involving 25 employees from the Service Department. Work productivity was assessed using productive man-hours, nutritional status was determined by Body Mass Index (BMI), dietary patterns were evaluated using the Semi-Quantitative Food Frequency Questionnaire (SQ-FFQ), sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI), and physical activity was assessed using the Global Physical Activity Questionnaire (GPAQ). Data were analyzed using Spearman correlation and ordinal logistic regression. The results showed that 72.0% of the subjects were overweight or obese, fruit and vegetable consumption remained low, most subjects had good sleep quality (84.0%) and moderate physical activity levels, and 48.0% achieved the highest productivity category (Grade A). Nutritional status (p=0.339), energy adequacy (p=0.628), protein adequacy (p=0.877), fat adequacy (p=0.777), carbohydrate adequacy (p=0.675), and physical activity (p=0.788) were not significantly associated with work productivity. In contrast, sleep quality was significantly associated with work productivity (p=0.025; r=0.448). Improving sleep quality through effective rest management and workplace health promotion programs may help enhance employee productivity.
