<p>Besi (Fe) salah satu unsur penting dalam permukaan air dan air tanah. Senyawa besi dalam jumlah kecil di tubuh manusia sebagai pembentuk sel-sel darah merah,tubuh memerlukan 7-35 mg/hari sebagian diperoleh dari air.Tetapi zat Fe yang melebihi dosis dalam tubuh akan menyebabkan masalah kesehatanseperti merusak dinding usus,berkurangnya fungsiparu-paru,dapat menimbulkan noda pada peralatan dan bahan yang berwarna putih.Tujuan penelitian ini untuk mengetahui penurunan kadar besi(Fe) pada air sumur bor dengan metode aerasi-filtrasi pada air sumur bor masyarakat Jalan Setia Budi, Kel.Tanjung Rejo.Jenis penelitian Quasi Eksperimental Design (Rancangan Eksperimen Semu) dengan desain Pre-Test dan Post-Test.Sampel air sumur bor diambil 1 sumur diKelurahan Tanjung Rejo.Pemeriksaan kadar besi(Fe)dilakukan oleh petugas Lab.Lingkungan.Hasil penelitian secara fisik air yang belum diberikan perlakuan memiliki warna kuning, berbau(karat atau tanah),dan air terasa licin ketika sudah diberikan perlakuan dengan lama kontak 30, 45 dan 60 menit dengan metode aerasi-filtrasi air tersebut jernih dan tidak berbau. Sebelum dilakukan aerasi-filtrasi didapat hasil sebesar 4,25mg/l dan proses penurunan kadar besi dengan Metode Aerasi-Filtrasi dengan lama kontak 30 menit sebesar 3,10 mg/l dan 45 menit sebesar 1,85 mg/l belum memenuhi syarat.Pada waktu kontak 60 menit sebesar 1,00 mg/l dan sudah memenuhi syarat baku mutu sesuai Permenkes No.32 Tahun 2017, kadar maksimum besi sebesar 1,00 mg/l.</p>

Background: World Health Organization (WHO) has declared Coronavirus Disease 2019 (COVID-19) as a pandemic. Interventions are needed not only in terms of implementing health protocols but also other effective interventions to decrease the transmission of disease through vaccination efforts which are aimed at reducing transmission/transmission of COVID-19, reducing morbidity and mortality due to COVID-19, and achieving group immunity in the community society (herd immunity).Objective: The purpose of this study was to identify the implementation of a health belief model for the implementation of vaccination in the context of overcoming the COVID-19 pandemic in health workers within the Nagan Raya District Health Office.Method: The type of research used a descriptive-analytic approach with a cross-sectional study design with a total sampling method of sampling. The sample in this study was 76 health workers from a population of 76 health workers at the Nagan Raya District Health Office. This study was conducted from March to September 2021. Data analysis used Chi-Square statistical test and Binary Logistic Regression with a significance level of 95%.Results: The results of this study indicate that there is a significant relationship between perceived susceptibility (p = 0.041), perceived benefits (p = 0.047), and cues to action (p = 0.037) with the implementation of vaccination in the context of dealing with the COVID-19 pandemic for health workers. There is no relationship between perceived severity (p = 1,000) and perceived barriers (p = 0,280) with the implementation of vaccination in the context of dealing with the COVID-19 pandemic in health workers.Conclusion: The dimension of the health belief model that is highly dominant related to the implementation of vaccination in the context of dealing with the COVID-19 pandemic in health workers is the perceived susceptibility variable with a value of p= 0.041 and Exp (B) = 5.376.

<p><em>Kelelahan kerja menunjukkan kondisi yang berbeda–beda dari setiap individu,  semua bermuara kepada kehilangan efisiensi dan penurunan kapasitas tubuh serta peningkatan peluang untuk cidera di tempat kerja. Pemanen Sawit merupakan salah satu pekerja yang beresiko mengalami kelelahan, dimana pekerjaannya dilakukan secara manual, atau aktivitas kerja dengan pembebanan fisik. Kelelahan kerja dipengaruhi  oleh  faktor dari pekerja dan luar pekerja.Oleh karena itu perlu dilakukan penelitian mengenai hubungan  karakteristik  pekerja seperti umur, masa kerja, riwayat penyakit dan status gizi, serta beban kerja dengan tingkat kelelahan kerja pekerja. Tujuan  penelitian  untuk mengetahui hubungan karakteristik pekerja dan beban kerja dengan kelelahan kerja pada pemanen sawit di PT Bakrie Sumatera Plantations Tbk. Jenis penelitian analitik, pendekatan cross sectional. Sampel dengan metode total sampling yaitu sebanyak 64 responden. Hasil  penelitian  diperoleh  ada  hubungan  antara  umur  dengan  kelelahan  kerja (p=0.000),  ada  hubungan  antara  masa kerja dengan kelelahan kerja (p=0.001), ada hubungan  antara  riwayat  penyakit  dengan  kelelahan  kerja (p=0.001), ada  hubungan antara  status  gizi  dengan  kelelahan  kerja (p=0.001), dan  ada  hubungan  antara  beban kerja  dengan kelelahan kerja (p=0.017). Berdasarkan  hasil  penelitian  ini  disarankan  agar  perusahaan  melakukan  rotasi kerja  berdasarkan  kemampuan  fisik  dan  ketahanan  kerja  pemanen,  serta  memberikan safety  talk  untuk  melakukan  peregangan  tubuh  selama  10  menit.</em></p><p><em><br /></em></p><p><em>Fatigue shows the condition of each individual, all leading to loss of efficiency</em><em>,</em><em>a decrease in body capacity</em><em>, </em><em>an increased chance of injury at work.
