ABSTRAK
Kebisingan merupakan salah satu faktor lingkungan tempat kerja yang dapat mempengaruhi kesehatan petugas ground handling yang bertugas di apron bandar udara. Berdasarkan pengukuran yang dilakukan petugas kesehatan terhadap petugas ground handling yang datang ke pos Kantor Kesehatan Pelabuhan Kelas I Medan wilayah kerja Bandara Kualanamu, terdapat sejumlah petugas yang mengalami peningkatan tekanan darah diatas normal.
Penelitian ini bertujuan untuk menganalisis pengaruh intensitas kebisingan dan karakteristik pekerja terhadap tekanan darah petugas ground handling di apron Bandar Udara Internasional Kualanamu. Metode penelitian bersifat analitik dengan desain cross sectional. Penelitian ini dilaksanakan bulan Januari sampai dengan Maret 2014. Populasi adalah seluruh petugas ground handling berjumlah 106 orang dan seluruhnya dijadikan sampel dengan teknik total sampling. Pengumpulan data melalui wawancara dengan kuesioner, observasi dan pengukuran langsung. Analisis dilakukan secara univariat, bivariat dengan uji chi square dan multivariat dengan uji regresi logistik berganda pada pengujian α=0,05.
Hasil penelitian menunjukkan variabel yang berpengaruh terhadap perubahan tekanan darah petugas ground handling yaitu intensitas kebisingan, umur, masa kerja, penggunaan alat pelindung telinga dan pelatihan. Hasil uji regresi logistik berganda variabel yang paling dominan berpengaruh terhadap perubahan tekanan darah adalah intensitas kebisingan.
Petugas yang mengalami perubahan tekanan darah setelah bekerja rata-rata menerima intensitas kebisingan diatas NAB, memiliki umur diatas 28 tahun, dengan masa kerja lebih dari 5 tahun, tidak menggunakan alat pelindung telinga dan tidak pernah mengikuti pelatihan yang berhubungan dengan bidang pekerjaannya.
Petugas ground handling harus memiliki kesadaran dan disiplin untuk menggunakan alat pelindung telinga saat bekerja atau berada dalam lingkungan kerja.

ABSTRACT
e complete dical records and legal is charistic that reflects the good quality of medical services to patients. Based on preliminary survey at the
Noise is one of environment factors at work place that influence the health of ground handling staff at the airport apron. Based on measurement done by the health workers to the ground handling staff who came to the post of Port Health Office Class I Medan in the working area of Kualanamu International Airport, several of the staff were found to experience an above normal increase of blood pressure.
The purpose of this analytical study with cross-sectional design conducted from January to March 2014 was to analyze the influence of noise intensity and workers characteristics on the blood pressure of ground handling staff at the apron of Kualanamu International Airport. The population of this study was all 106 ground handling staff and all of them were selected to be samples for this study through total sampling technique. The data for this study were obtained through questionnaire-based interviews, observation and direct measurement. The data obtained were analyze through univariate analysis, bivariate analysis using Chi square test and multivariate analysis with multiple logistic regression test at α = 0,05.
The result of this study showed that the variables that influenced the change of the ground handling staff’s blood pressure were noise intensity, age, length of servive, the use of hearing protection devices (ear muff) and training. The result of multiple logistic regression test showed that the most dominant variable influencing the change of blood pressure was noise intensity.
The average of ground handling staff experiencing the change of blood pressure worked under the noise intensity above NAB, were over 28 years old, with length of service more than 5 years, did not use any hearing protection (ear muff) and never attended any training related to their work area.
The ground handling staff should have awareness and discipline to use ear protective devices at work or in the work environment.
