Abstrak: Keberadaan benzena dalam lem alas kaki ini membahayakan kesehatan para pekerja di bengkel alas kaki karena sifatnya yang toksik dan karsinogenik. Dampak yang ditimbulkan adalah terganggunya sumsum tulang yang merupakan tempat produksi sel darah merah, darah putih dan trombosit. Tujuan dari penelitian ini adalah menganalisis hubungan pajanan benzena melalui pemeriksaan konsentrasi S-phenylmercapturic acid (S-PMA) di urin terhadap kadar trombosit pada pekerja bengkel alas. Desain dari penelitian adalah cross sectional pada pekerja pabrik alas kaki di Desa Sukajaya dengan jumlah sampel 73 pekerja. Sampel yang diambil adalah urin dan darah dari pekerja untuk mengetahui konsentrasi S-PMA dan kadar trombosit. Konsentrasi S-PMA diukur dengan alat LC-MS/MS dan trombosit dengan Automated Hematology Analyzer. Karakteristik individu dengan wawancara secara langsung. Hasil penelitian menunjukkan nilai OR=2,28 antara konsentrasi S-PMA terhadap kadar trombosit. Variabel kebiasaan olahraga dengan OR=1,58 antara olahraga tidak rutin terhadap trombosit dan konsumsi alkohol OR=1,78 antara yang mengkonsumsi terhadap kadar trombosit. Hasil uji regresi logistik multivariabel menunjukkan nilai OR=2,59 pekerja dengan konsentrasi S-PMA (>0,67 μg/g kreatinin) terhadap kadar trombosit setelah dikontrol variabel umur dan konsumsi alkohol.

The existence of benzene in the glue of footwear is endangering the health of the workers in the footwear workshop because of its toxic and carcinogenic nature. The impact is the disruption of the bone marrow which is where the production of red blood cells, white blood and platelets. The purpose of this study was to analyze the relationship of benzene exposure through the examination of S-phenylmercapturic acid (S-PMA) concentration in urine on platelet levels in base workshop workers. The design of the study was cross sectional on footwear factory workers in Sukajaya Village with a sample of 73 workers. Samples taken are urine and blood from workers to know the concentration of S-PMA and platelet levels. The concentration of S-PMA was measured by LC-MS / MS and platelets with Automated Hematology Analyzer. Individual characteristics with direct interview. The results showed the value of OR = 2.28 between S-PMA concentration to platelet level. Variables of exercise habits with OR = 1.58 between non-routine exercise on platelets and alcohol consumption OR = 1.78 among those who consume to platelet levels. Multivariable logistic regression test results showed OR = 2.59 workers with S-PMA concentration (> 0.67 μg / g creatinine) on platelet count after controlled for age and alcohol consumption.

Abstrak: Pajanan kronis benzena di lingkungan kerja selalu dihubungkan dengan gangguanhematologi. Hal ini dikarenakan sistem hematologi adalah jaringan target yangpaling kritis terhadap pajanan benzena melalui rute inhalasi dan diketahui sebagaipenyebab pansitopenia. Penelitian ini bertujuan untuk menganalisis hubunganantara kadar S-PMA urin dengan leukosit pada pekerja industri sepatu informalyang terpajan benzena. Penelitian menggunakan desain cross sectional di enamindustri sepatu informal yang berada di kawasan Cibaduyut dengan jumlah sampel64 pekerja. Sampel urin dan darah diambil pada masing-masing sampel untukmenilai kadar S-PMA urin dan jumlah leukosit. Kadar S-PMA urin diukur denganmenggunakan alat LC-MS/MS dan leukosit diukur menggunakan alat AutomatedHematology Analyzer. Data karakteristik individu diperoleh melalui wawancaralangsung. Konsentrasi benzena di udara menggunakan data sekunder daripenelitian sebelumnya. Hasil penelitian menunjukkan bahwa terdapat hubunganyang signifikan antara kadar S-PMA dengan leukosit (p value: 0,048) dan kadarS-PMA urin dengan jenis pekerjaan (p value: 0,004). Sebanyak 31,3% pekerjamemiliki kadar S-PMA urin melampaui BEI ACGIH (>25 μg/g kreatinin).Semakin tinggi konsentrasi benzena di udara ruang kerja, semakin banyak pekerjayang memiliki kadar S-PMA urin >25 μg/g kreatinin. Hasil uji regresi linearganda menemukan bahwa ada kecenderungan asosiasi antara kadar S-PMA urindengan leukosit, setelah dikontrol dengan variabel jenis pekerjaan, jam kerja perhari, dan kebiasaan berolahraga. Hasil penelitian dapat disimpulkan terdapatasosiasi antara kadar S-PMA urin dengan penurunan jumlah leukosit.Kata kunci: benzena, S-phenylmercapturic acid, leukosit, industri sepatu informal

Benzene high exposure in working is environment always connected tohematology disorders. This is caused by hematology system is the most criticaltarget network toward benzene exposure through inhaling route. This study aimsto analyze the relation between urinary and leukocytes S-PMA level of informalshoes industrial workers exposed to benzene. This study uses cross sectionaldesign in six informal shoes industries which are located in Cibaduyut with thenumber of sample of 64 workers. Urinary and blood samples are collected on eachsample to measure urinary S-PMA level and the number of leukocytes. Urinary S-PMA level is measured using Automated Hematology Analyzer. Individualcharacteristic data are obtained through direct interview. To measure benzeneconcentration, secondary data of previous study is used. The result of the studyindicates that there is significant correlation between S-PMA level withleukocytes (p value: 0.048) and urinary S-PMA level with the type of job (p value:0.004). By 31.3% workers have urinary S-PMA level more than BEI ACGIH (>25μg/g creatinine). The higher the benzene concentration of indoor air, the moreworkers have urinary S-PMA level > 25 μg/g creatinine. The result of doublelinear regression test finds that there is association tendency between urinary andleukocytes S-PMA level, after it is controlled by type of job, time of work perday, and exercising habit variables. It can be concluded that there is associationbetween urinary S-PMA level and the number of leukocytes decrease.Keywords: benzene, S-phenylmercapturid acid, leukocytes, informal shoesindustries
