ABSTRAK
Industri petrokimia beroperasi sepanjang jam, durasi kerja tanpa henti selama operasinormal, terlebih pada kegiatan turn around, program pemeliharaan yang harus sesuaitarget dan tepat waktu. Pada pelaksanaan turn around jumlah jam kerja diperpanjangtidak seperti hari biasanya, hal ini dapat mengakibatkan personil terganggu dengankuantitas tidur, kualitas tidur dan sleep hygiene individu, kondisi seperti inimengakibatkan potensi kelelahan akut, mengurangi performance dan berpotensimeningkatnya jumlah kejadian kecelakaan kerja. Penelitian analitik dengan desaincross-sectional ini bertujuan mengetahui pola dan gambaran kuantitas tidur, kualitastidur, durasi kerja pada tenaga kerja turn around terhadap potensi kelelahan kerja akut.Penelitian ini menggunakan beberapa alat pengumpulan data yaitu: kuesioner,tensimeter, thermogun dan alat actigraph fitbit. Analisis data menggunakan uji bedamean dan uji chi square. Hasil penelitian menunjukkan terdapat hubungan antaravariable kuantitas tidur (p value = 0,001; OR = 0,115), kualitas tidur (p value = 0,030;OR = 8,143), dan durasi kerja (p value = 0,013; OR = 5,769) dengan variable potensikelelahan kerja akut, penelitian ini terbukti dengan hasil pengukuran actigraph fitbitdengan rata-rata tidur 235 menit atau setara dengan 3 jam 55 menit serta durasi kerjayang lebih dari 12 jam setiap harinya selama kegiatan turn around.

ABSTRACT
The petrochemical industry is a 24‐hour a day industry, and thus at very high risk forhaving employees who feel fatigued and could potentially make mistakes as a result,especially in turnaround project, this systematic activities and able to completemaintenance program which is on-time and targeted. In the turn around project, thenumber of working hours is prolonged. It causes the employees experiencing problemsin sleep quantity, quality and individual sleep hygiene. The condition produces an acutefatigue, less performance, and probably increases the number of accidents in theworkplace. An analitic research using cross-sectional design has a purpose to find outthe cycle and description of quantity and quality of sleep, working duration of turnaround employees to the potential of acute working exhaustion. This research use somedata collecting tools, namely: questionnaires, tension meter, thermogun and actigraphfitbit. The data analysis used mean different test and chi square test. The result of thisresearch showed that there was a relationship between sleep quantity variable (p value= 0.001; OR = 0.115) sleep quality (p value = 0,030; OR = 8,143) and working duration(p value = 0.013; OR = 5.769) with the variable of acute working fatigue tendency. Thisresearch, using actigraph fitbit measurement, proved that the average of sleep was 235minutes or similar with 3 hours 55 minutes and the daily working duration was morethan 12 hours during the turn around operation.
