Pekelja di kilang minyak tcrutama di lokasi bising mempunyai risiko tinggi menderita gangguan pcndcngaran sebagai penyakit akibat kelja. Pajanan kombinasi (bising, penyakit DM, hipcrtensi, DM dan hipertensi) dapat terjadi secara bersamaan pada seorang pekerja. Penelitian bertujuan untuk mengetahui hubungau dan kontribusi pajanan kombinasi terhadap teljadinya gangguan pendengaran. Dengan metode historikal kohor, data pekelja dari tahun 2002-2007, pcfnetapan kriteria gangguan pendengaran berdasarkan hasil audiogram pada frekuensi 4000 Hz > 25 dBA, status DM berdasarkan kriteria diagnostik PERKENI 2006 GDP 2126 mg/dL, status hipertensi herdasarkan JNC7 S 2140 mmHg dan D 290 mm!-Ig. Analisis statistik dengan univariat dan bivariat. Diperoleh hasil, insiden gangguan pendengaran berkisar antara 25.0% - 50.0% pada pekelja yang terpzgan bising, dengan distribusi responden menurut masing- masing pajanan kombinasi dan karakteristik responden (variabcl pcrancu: Lunur; rnasa kerja; merokok; dan pemakaian APT). Kesimpulan yang diperoleh dari uji statistik, baik variabel independen maupun vadabel perancu mempunyai p value > on, perbedaan tidak bermal-ma. Sehingga gambaran dan kontribusi faktor risiko penyakit DM dan hipcrtcnsi bclum dapat diketahui dengan jelas. Hal ini disebabkan beberapa keterbatasan penelitian diantaranya sampel yang mcmenuhi kriteria inklusi (140 responden) tidak memenuhi besar sampel minimal (287 responden}, informasi data yang diperoleh dari perusahaan tidak lengkap. Oleh karenanya saran bagi pemsahaan agar lebih memperhatikan sistem pencatatan, pelaporan, dan penyimpanan data., pemeriksaan audiometri, kesehatan berkala, pengukuran dosis pajanan, secara rutin dan berkcsinarnbungan sesuai kebutuhan, terulama bagi pekerja yang terpajan bising > 85 dBA, penertiban sertifikasi operator, kalibrasi alat oleh institusi yang bezwenang.
Workers of refinery in noisy area have high risk to get hearing loss as occupation disease. Combined exposure (noise, DM, hypertension) can happen simultaneously on a worker. The purpose of this study is to find the relation and contribution of combined exposure on hearing loss. The study was using historical cohort, worker’s data from 2002 to 2007, hearing loss criteria definition based on audiograrn result with frequency 4000 Hz >25 dBA; DM status based on PERKENPS diagnosis in 2006 GDP 2 126 mg/dL, hypertension status based on JNC7 S 2 |20 mml-lg and D 2 90 mml-Ig. Statistical analysis was using univariat and bivariat. The result is hearing loss incident on workers exposed by noise around 25.0% - 50.0%, with respondent’s distribution based on each combined exposure and respondent's characteristic (confounding variable : age, working period, smokind and the using of APT) We conclude by statiscal test, both independent variable and cofounding variable with P value > ot that there is insignificant dillerencetherefore, the illustration and contribution of DM and hypertension risk factor cannot be found clearly. It was caused by some limitations in the study such as inclusive criteria sample (140 respondents) didn't iillfil the quota of sample (287 respondents), incompleted company's clatas. Therefore, we suggest that the company should pay more attention to data entry, data report and data saving, audiometric check-up, periodic medical check-up, exposure dosage measurement, regularly and continually based on needs, especially for workers exposed by noise > 85 dBA, regulation of operator certification, calibrated equipment by authorized institution.
Gangguan pendengaran karena bising merupakan salah satu penyakit akibat kerja yang sering ditemui pada perusahaan manufaktur. Hazard yang bisa menyebabkan gangguan pendengaran meliputi bising, zat kimia dan getaran. Ruang lingkup penelitian tesis ini adalah melihat dampak pajanan bising terhadap fungsi pendengaran pekerja yang terpajan bising diatas 82 dBA. Jenis penelitian adalah cross sectional study yang meneliti hubungan faktor independen berupa dosisi pajanan dalam perhitungan leq, umur dan masa kerja serta faktor penggangu berupa pemakaian alat pelindung diri serta kebiasaan dengan fungsi pendengaran pekerja. Dari survei tingkat bising ditemukan departemen PVC, CDM, CDS dan CDB mempunyai tingkat kebisingan diatas nilai ambang batas yang diperbolehkan.
Hasil pemeriksaan audiometri ditemukan dua orang responden yang mengalami gangguan pendengaran. Responden yang mengalami gangguan pendengaran satu orang berumur diatas 40 tahun, bekerja pada ruangan PVC dimana merupakan tingkat pajanan bising tertinggi di pabrik ini dan sudah bekerja selama lebih dari 5 tahun. Responden yang mengalami gangguan pendengaran lainnya merupakan pekerja yang berumur dibawah 40 tahun dan sudah bekerja selama lebih dari 5 tahun. Dari hasil analisis statistik tidak ditemukan hubungan yang signifikan antara Leq pajanan bising, faktor masa kerja, pemakaian alat pelindung diri dan kebiasaan merokok dengan gangguan pendengaran. Ditemukan hubungan yang signifikan antara umur dan gangguan pendengaran dengan OD ratio 7.99.
Noise induced hearing loss is one of the occupational diseases are often found in manufacturing companies. Hazard that can cause hearing loss include noise, chemicals and vibration. The scope of this thesis research on the impact of noise exposure on hearing function of workers exposed to noise above 82 dBA. This type of research is a cross-sectional study examining the relationship be an independent factor in the noise dose exposure (leq), age and working period and disturbance factors such as the use of personal protective equipment, smoking with hearing function. From the survey found noise levels PVC department, CDM, CDS and CDB have noise levels above the permitted threshold value.
Audiometric examination found two participant who suffered from hearing loss. Respondents who suffered from hearing loss a person aged over 40 years, working on PVC indoor noise exposure level which is the highest in the plant and it has been working for more than 5 years. Other participant who suffered from hearing loss is under the age of 40 years and has been working for more than 5 years. From the analysis found no statistically significant relationship between Leq noise exposure, working period, the use of personal protective equipment and smoking with hearing loss. Found a significant relationship between age and hearing loss with OD ratio 7.99.
Noise level in Water Treatment Plant (WTP) is high enough. Increasing the need for clean water in line with the increasing population, making the Water Supply Company (PDAM) is required to increase production capacity. There are machines and production processes that have different characteristics than other types of industries. There are 306 PDAMs throughout Indonesia, the potential number of workers exposed to noise is very large, it is necessary to further investigate the relationship between noise characteristics and its determinants to hearing loss to PDAM workers to obtain the most appropriate form of control. This study used a cross sectional study design. The stages of this study are to measure the noise level and provide questionnaires as primary data, analyzing the worker audiometric results as secondary data and using Chi Square statistical test and multi determinant analysis to find out the relationship between independent and dependent variables. The results obtained that the source of noise in water treatment plants are pumps, exhaust fan, compressor, blower, vacuum and waterfall. About 84.4% of workers in the production area exposed to noise > 85 dBA. About 15.6% of workers have hearing loss. It is concluded that exposure workers over 85 dBA with dominant noise frequency > 2000 Hz can cause hearing impairment and aggravate if workers are > 40 years old and have a working life > 14 years. Key words: Noise, Water supply company, Hearing loss, Noise frequency
This cohort study examined the effect of secondhand smoke exposure in pregnant women on fetal growth restriction. The study recruited 128 pregnant women in the third trimester pregnancy, single pregnancy, no chronic illness, non-active smokers, non-exsmokers, and who were willing to participate in the study. Pregnant women with the secondhand smoke exposure referred to those with the umbilical cord blood nicotine level of 1ng/ml or higher. Fetal growth disorder was assessed according to the newborn weight, length, head circumference, and palcental weight measured immediately after birth. The independent t-test analysis was used to determine the difference in average size of fetal growth between two groups of pregnant women: exposed and the notexposed to the secondhand smoke. A multiple linear regression analysis was employed to find out the effect of secondhand smoke exposure on birth weight, length, head circumference, and palcental weight controlling for the birth size confounders including weight gain during pregnancy, body mass index, parity, maternal age, and maternal hemoglobin. The study found that mean of nicotine in umbilical cord blood was 1.3±2.5 ng/ml, the birth weight and the placental weight of infants were lower among mothers who exposed than among mothers who did not expose to the secondhand smoke. Exposed to the secondhand smoke reduced the birth weight by 205.6 grams (p value = 0.005) and placental weight by 51 grams (p value=0.010).
