Tesis ini untuk membuktikan hepotesa bahwa pajanan debu total pada industri semen memegang peran dominan dalam kasus terjadinya kelainan fungsi paru. Melalui studi ini, dicari hubungan antara kelainan paru obstruktif pada pekerja yang terpajan debu total di industri semen dengan (1) konsentrasi debu total terpajan, (2) umur pekerja, (3) lama pajanan, (4) kebiasaan merokok, dan (5) kebiasaan menggunakan alat pelindung diri (APD). Studi dengan teknik potong lintang (cross-sectional) ini dilaksanakan di sebuah pabrik semen di Jawa Barat pada 2003, di antara 604 pekerja yang menderita kelainan fungsi paru. Data pribadi (n = 104) dari pengukuran debu terisap menunjukkan pajanan rata-rata. Kuesioner digunakan untuk menggali data tentang kebiasaan merokok, kebiasaan menggunakan APD, dan lama pajanan. Fungsi paru diukur dengan spirometer untuk menentukan jenis kelainan. Pajanan debu total diperoleh melalui penggunaan personal dust sampler dan kemudian ditimbang dengan timbangan elektronik. Berdasarkan data yang dianalisis, tampak bahwa tidak terdapat hubungan di antara variabel-variabel. Kesimpulan dari studi ini adalah tidak adanya hubungan antara pajanan debu total di bawah nilai ambang batas (NAB) dan kasus terjadinya kelainan fungsi paru obstruktif.

Study on Cement Dust and Another Factors against Obstructive Lung DisfunctionThis thesis hypothesized in cement industry that expose to total dust plays dominant role in the incidence of obstructive lung disfunction. The purpose of this study was to relate the obstructive lung disjunction in workers exposed to total dust in cement industry to (1) the concentration of total exposed dust, (2) the worker's age, (3) the length of exposure, (4) the smoking habit, and (5) the usage of personal protective equipment (PPE). A cross-sectional study in a cement plant in West Java was done in 2003, among 604 workers who suffering from lung disfunction. Personal sampling (n --104) of inhalable dust measurements indicated average exposure. Questionnaires were used to explore data about the smoking habit, the usage of PPE, and the length of exposure. Lung function was measured with spirometer to determine the type of the disjunction. The total dust exposure obtained by personal dust sampler (IDS) and electronic scale weighted. According to the result of data analyses, there's no relations among the variables. The conclusion of this study was that there is no relationship between total dust exposure (below the TLVs) and the incidence of obstructive lung disfunction.

Abstrak :
Penelitian ini merupakan sebuah observasi bersifat deskriptif yang dilihat secara potong lintang (cross sectional) pada sebuah pabrik semen di Jawa Barat pada tahun 2003. Tujuan utama: untuk melihat angka kunjungan poliklinik dan angka absensi karena keluhan pernafasan pada pekerja yang terpajan debu semen mengukur prevalensi kelainan Minis penyakit paru, penurunan fungsi paru dan kelainan fototoraks. Cara dan metodologi: Subjek adalah pekerja non staf di dua plant yang berdekatan dalam satu manajemen. Seluruh subjek diwawancara dengan menggunakan kuesioner standar ATS yang telah dimodifikasi. Fungsi paru diperiksa dengan spirometer dan fototoraks diambil sesuai dengan standar ILO. Kedua data didapat dari hasil pemeriksaan check-up terakhir. Data debu lingkungan dan pajanan debu didapat dari hasil pengukuran yang dilakukan perusahaan tiap tabula Angka kunjungan didapat dari rekam medik dan jumlah jam kerja didapat dari data personalia Subjek dibagi dua kelompok, yaitu yang terpajan debu (pekerja di area raw mill, burning, finish milt, packing, coal mill, mekanik dan elektrik) serta yang tidak terpajan debu (bagian adminstrasi dan kontrol panel). Hasil dari 301 subjek yang diperiksa, 16,8% pekerja yang terpajan debu menderita batuk kronis, 2,5% bronkitis kronis. 2,0% asma dan 10,2% flu karena alergi.Penurunan fungsi paru obstruksi terdapat pada 7,0%pekerja, restriksi 8,3%. Kelainan foto toraks klasifiksi ILO dengan perselubungan 110 terdapat pada 21,9% pekerja, sedangkan perselubungan 111 pada 1,3%. Angka kunjungan poliklinik pekerja terpajan debu dan tidak terpajan sama besarnya, yaitu 1,15%. Sedangkan angka absensi pekerja terpajan debu 1,22 permil banding 0.75 permil yang tidak terpajan debu. Kesimpulan: Terdapat perbedaan cukup nyata angka absensi antara pekerja terpajan debu dengan tidak terpajan debu, tetapi tidak terdapat perbedaan angka kunjungan poliklinik.

Policlinic Visite and Non Effective Rate Cause by Occupational Lung Disease Due to Cement DustThis research was a descriptive observation with a cross-sectional view on a cement factory located in West Java in 2003. Main objectives: to find out the policlinic visit rate and the non effective rate due to respiratory problems among workers exposed to cement dust and to measure the prevalence of lung clinical disorders, decrease of lung functional and abnormality in chest radiographs. Procedure and Methodology: Subject were non-staff workers into adjacent plants under one management All subjects were interviewed by using ATS standard questionnaires that have been modified. Lung function was done by using spirometer and chest radiographs in compliance with ILO standards. Both data were obtained from the result of the last medical checkup. Data of environmental dust and dust exposure were obtained from the result of semester measurement The rate of visit was obtained from the medical record and total working hours obtained from the personnel data Subjects were devided into two groups, namely workers exposed to dust (workers in raw mill, burning, finish mill, packing, coal mill, as well as mechanical and electrical areas) and workers not exposed to dust (administration and control panel divisions). Results: Out of 301 subjects examined, 16,8% of workers exposed to dust were suffering from chronic cough, 2,5% were suffering from chronic bronchitis, 2,0% asthma and 10,2% flu due to allergy. Decreases of lung function was found in 7,0% obstructive and 8,3% restrictive of the workers. Abnormality in chest radiographs based on ILO classification with a density of 110 and 111 was found 21.9% and 1.3% of the workers. Workers exposed and not exposed to dust had a similar rate of policlinic visit rate. namely 1.15%. Whereas the not effective rate of exposed to dust was 1,22 per mil compared to 0,75 per mil of workers not exposed to dust. Conclusion: There was a significant difference in the non effective rate workers exposed to dust and those not exposed to dust, but there was no difference in the policlinic visit rate.
