"Tesis ini membahas efek modifikasi status hidrasi dengan memperhitungkan Indeks Massa Tubuh (IMT) pada petugas ground handling di Bandara Soekarno Hatta. Yang sering terpajan panas dalam waktu lama, yang dapat menyebabkan dehidrasi dan kelelahan. Lestari (2016) dalam penelitiannya menyatakan iklim kerja yang panas dan melebihi NAB dapat meningkatkan risiko terjadinya dehidrasi.  Penelitian ini menggunakan pendekatan cross sectional, 219 responden yang bekerja di dalam Gedung dan apron. Status hidrasi diukur menggunakan berat jenis urin, IMT diukur dengan berat badan dan tinggi badan, dan kelelahan diukur menggunakan kuisioner IFRC. Hasil penelitian 63,5% responden mengalami kelelahan berat dan 36,5% mengalami kelelahan ringan. 70,3% pekerja memiliki status hidrasi yang baik, sementara 29,7% mengalami dehidrasi. 58,9% responden obesitas dan sisanya 41,1% tidak obesitas. Hasil analisis statistik menunjukkan tidak ada hubungan signifikan antara status hidrasi terhadap kelelahan kerja (p-value 0,340), ada hubungan signifikan antara IMT dengan kelelahan (p-value 0,014). Ada interaksi antara status hidrasi dengan IMT. Analisis multivariat menyatakan ada hubungan signifikan antara efek modifikasi status hidrasi dengan memperhitungakan IMT terhadap kelelahan (p-value 0,022 dan cOR 1,184). Hal ini menunjukkan bahwa terdapat pengaruh status hidrasi terhadap tingkat kelelahan kerja bergantung atau bervariasi menurut status IMT, sehingga diketahu nilai OR pada IMT obesitas (kode 1) adalah 1,46. Artinya responden yang obesitas dengan status dehidrasi berisiko 1,46 kali lebih tinggi pada responden yang mengalami kelelahan berat dibandingkan dengan status euhidrasi setelah dikontrol oleh faktor risiko terkait pekerjaan dan faktor risiko tidak terkait pekerjaan.

This thesis discusses the effect of hydration status modification considering Body Mass Index (BMI) on ground handling workers at Soekarno Hatta airport. Those worker are often exposed to prolonged heat, which can cause dehydration and fatigue. Lestari (2016) stated that a hot working climate exceeding TLV can increase the risk of dehydratin. This cross-sectional study involved 219 respondents working inside buildings and the apron. Hydration status was measured using urin specific gravity; BMI was measured with weight and height; and fatigue was measured using the IFRC questionnaire. The result showed that 63,5% of respondents experienced severe fatigue and 36,5% experienced mild fatigue; 70,3% of workers had good hydration status, while 29,7% were dehydrated; 58,9% of respondents were obese and the remaining 41,1% were not obese. Statistical analysis results showed no significant relationship between hydration status and work fatigue (p-value 0,340), but there was a significant relationship between BMI and fatigue (p-value 0,014). There was an interaction between hydration status and BMI. There was also a significant relationship between the effect of hydration status modification considering BMI on fatigue (p-value 0,022 amd cOR 1,184). This shows that the impact of hydration status on the level of work fatigue varies depending on BMI status. The OR value for obese BMI (code 1)was 1,46; meaning that obese respondents with dehydration were 1,46 times more likely to experience severe fatigur compared to respondents with good hydration status, after controlling for work-related and non-work-related risk factors."
