Introduction: Work fatigue can be caused of excessive workload and work capacity such as age and tenure. This study aimed to analyze the strength of the correlation between individual factors and mental workload with work fatigue on the Surabaya Patchouli Terminal crane operator. Methods: The study design is a cross sectional. The sampling technique taken was total sampling so that all populations were a sample of 30 people, consisting of CC and RTG operators in Nilam Terminal Surabaya. The independent variables are individual factors including age and years of service obtained from the questionnaire, mental workload which is assessed based on the NASA-TLX questionnaire, while the dependent variable is work fatigue measured using a reaction timer. The collected data were then analyzed using the Spearman correlation. Results: The results show 23 operators (76.7%) experienced heavy work fatigue and 7 operators (23.3%) experienced moderate work fatigue. Conclusion: The strongest correlation is mental workload with work fatigue and the weakest correlation is age with work fatigue. Meanwhile, correlation tenure with work fatigue is in between. It is recommended to provide psychological consultation once a week for operators.

Latar Belakang: Infeksi Saluran Pernafasan Akut (ISPA) merupakan penyakit saluran pernapasan atas atau bawah yang biasanya bersifat menular dan dapat mengakibatkan berbagai spektrum penyakit. ISPA masih menjadi masalah kesehatan yang serius di negara berkembang seperti Indonesia. Tak hanya menyerang orang dewasa saja, ISPA juga menjadi penyebab utama kematian pada balita. Prevalensi ISPA di Indonesia pada tahun 2018 mencapai 9,3%, sedangkan prevalensi kasus ISPA pada balita di Bojonegoro mencapai  17,75% (Kemenkes, 2018). Berdasarkan data yang diperoleh peneliti dari posyandu Desa tercatat kasus ISPA pada tahun 2019 mencapai 253 kasus. Sebanyak 28 kasus ISPA terjadi pada balita usia 0-2 tahun. Tujuan: Menganalisis hubungan antara pemeliharaan hewan ternak di dalam rumah dengan kejadian ISPA pada balita usia 0-2 tahun di Desa Tlatah Kecamatan Purwosari Kabupaten Bojonegoro. Metode: Penelitian ini bersifat observasional dengan pendekatan cross sectional. Populasi dan sampel dalam penelitian ini adalah semua balita berusia 0 – 2 tahun di Desa Tlatah Kabupaten Bojonegoro yang berjumlah 40 orang sehingga teknik pengambilan sampel menggunakan total sampling. Data dikumpulkan menggunakan teknik wawancara dan observasi. Kemudian data dianalisis menggunakan uji chi-square. Hasil: Penelitian tidak menunjukkan adanya hubungan pemeliharaan hewan ternak dengan kejadian ISPA pada balita karena p = 0,364 > α = 0,05. Kesimpulan: Tidak terdapat hubungan antara pemeliharaan hewan ternak dengan kejadian ISPA pada balita di Desa Tlatah Kabupaten Bojonegoro. Kata kunci: ISPA, balita, hewan ternak

Introduction: Work accidents can occur due to two factors, namely unsafe human behavior and unsafe environmental conditions. One of the unsafe human behavior is work fatigue. In addition, work fatigue can also reduce productivity so that it can have a bad impact on the company. This study aims to determine the strength of the relationship and the direction of the correlation between nutritional status and work postures with work fatigue on crane operators. Method: This research is included in the type of descriptive observational research with a cross-sectional approach. The sample of this study was taken using total sampling, namely all the population of 30 people. The independent variables in this study were nutritional status and body postures, while the dependent variable was work fatigue. The data were analyzed using the Spearman's correlation coefficient (Spearman rank's correlation coefficient) to see the value of the correlation coefficient. Results: The correlation coefficient between nutritional status and work fatigue was -0.169, which means there was a very weak relationship with a negative direction. Meanwhile, the strength of the relationship between work postures and work fatigue can be seen in the correlation coefficient of 0.671, which means there was a strong relationship with a positive direction. Conclusion: Workers with overweight and obese nutritional status wwere more relaxed at work and did not pursue daily targets so that the fatigue experienced was classified as moderate. In addition, poor work postures can cause severe work fatigue.
