Research into the analysis of mercury levels in hair with impaired central nervous system function for gold mining workers, was conducted to provide a reference to the impact of mercury use and its prevention for public health. The method in this research use cross sectional design. This research used secondary data from Ministry of Health, with 119 miners as samples. The results of the measurement of mercury in the hair of workers, obtained 77.9% above normal, Biology Exposure Index value ≤ 3μg / g (ACGIH, 2005). Analysis of mercury levels in the hair with impaired function of the central nervous system, the statistical calculation showed no significant relationship, but workers with high mercury levels risked 3.12 times, 95% CI (0.67 - 14.36) against impaired functioning of the nervous system center. Analysis of various confounding factors, namely: Length of exposure, consumption of fruits, fish consumption, pesticide and or insecticide use and smoking habits, based on statistical calculations, only the use of pesticides has a constant relationship between them and 3.97 times risk, 95% (1.51 - 10.43) against impaired functioning of the central nervous system. The result of multivariate analysis, obtained by respondent with high mercury in hair, had 2.82 times greater risk with 95% CI (0,595-13,379) for impaired function of central nervous system after controlled variable of pesticide usage. Prevention and control of health impacts due to the use of mercury should involve various parties, government, private and public, through elimination, substitution, technical and administrative control programs.

Kelelahan merupakan hal umum yang dikeluhkan oleh pekerja dan hampir 20% pekerja melaporkan gejala kelelahan. Khusus pada pengemudi, kelelahan berkontribusi secara signifikan terhadap kecelakaan transportasi. Selain meningkatnya kerugian akibat kecelakaan, kelelahan mengemudi juga menyebabkan kerugian finansial yang besar di sesluruh dunia. Kelelahan mengemudi juga dialami oleh pekerja tambang batubara di Indoneisa, khususnya pekerja operator. Penelitian ini bertujuan untuk mendapatkan determinan strategis kelelahan dari faktor individu, faktor pekerjaan dan faktor eksternal pada operator tambang batubara di Kalimantan dan Sumatra tahun 2021. Penelitian ini menggunakan desain potong lintang pada 2 perusahaan tambang batubara, 7 lokasi tambang, dan 480 operator. Pengumpulan data dilakukan secara daring dengan menggunakan kuesioner. Kelelahan diukur dengan menggunakan 3 instrumen yaitu checklist individual streght-20 (CIS-20), multidimensionall fatigue inventory-20 (MFI-20), dan swedish occupational fatigue inventory (SOFI). Tipe kelelahan yang diteliti meliputi kelelahan umum, kelelahan fisik, kelelahan mental, dan kelelahan emosional. Beberapa instrumen standar juga digunakan dalampenelitian ini seperti perceived stress scale untuk mengukur stres, dutch boredom scale untuk mengukur rasa bosan, dan Pittsburg sleep quality index untuk mengukur kualitas tidur. Analisis data menggunakan chi-square dan regresi logistik ganda. Operator yang menjadi responden penelitian mempunyai umur 32,13 ± SD 6,1 tahun (21 – 58 tahun), sedangkan IMT diperoleh rerata sebesar 24,86 ± SD 3,1 dengan rentang (16,51 – 33,75) serta IMT terbanyak 24,22. Terdapat 26,9% operator termasuk kategori obesitas. Mayoritas operator sudah menikah (85%) dan sebagian besar (63,5%) tinggal di luar mess dengan keluarga (55,8%) serta mayoritas (96%) berpendidikan SMA atau sederajat. Rerata masa kerja operator adalah 9,52 ± SD 4,2 tahun dengan rentang (124 tahun) serta masa kerja terbanyak adalah 10 tahun. Sebagian besar operator bekerja di area tambang (65,8%). Jumlah operator berdasarkan pola shift dan waktu shift, masingmasing 240 (50%). Prevalensi kelelahan pada operator berkisar antara 20%-31% dengan kelelahan umum 24,8%, kelelahan fisik 22,3%, kelelahan mental 32,3%, dan kelelahan emosional 30,6%. Determinan strategis kelelahan pada operator terdiri dari faktor individu yang meliputi tingkat stres, kualitas tidur, gangguan eksternal tidur, faktor pekerjaan meliputi lokasi kerja di tambang, dan faktor eksternal yaitu tinggal dengan keluarga. Sedangkan faktor pola shift kerja dan masa kerja merupakan faktor kontekstual. Faktor yang menjadi determinan pada semua tipe kelelahan adalah faktor tingkat stres dan lokasi kerja. Determinan strategis pada kelelahan umum adalah tingkat stres (OR=3,0), lokasi kerja (OR=2,5), kualitas tidur (OR=1,8), dan tinggal dengan keluarga (OR=1,6). Pada kelelahan fisik, determinan strategis adalah tingkat stres (OR=2,5), gangguan eksternal tidur (OR=2,2), dan lokasi kerja di tambang (OR=1,7). Kelelahan mental mempunyai determinan strategis yaitu kualitas tidur (OR= 2,1), lokasi kerja di tambang (OR=2,1), tingkat stres (OR=1,7) dan gangguan eksternal tidur (OR=1,6). Sedangkan kelelahan emosional mempunyai determinan strategis yaitu tingkat stres (OR=2,0), lokasi kerja (OR=1,9), dan kualitas tidur (OR=1,9). Kelelahan emosional juga mempunyai faktor pola shift yang merupakan faktor kontekstual dengan OR= 1,9 dan masa kerja dengan OR=1,6. Dapat disimpulkan bahwa determinan kelelahan pada operator tambang batubara meliputi faktor individu, faktor pekerjaan, dan faktor eksternal. Kelelahan mental merupakan tipe kelelahan yang paling banyak dirasakan oleh operator. Determinan kelelahan yang terdapat pada semua tipe kelelahan adalah tingkat stres dan lokasi kerja. Semua determinan dapat menjadi perhatian dalam pengembangan kebijakan dan program manajemen risiko kelelahan di perusahaan tambang batubara.

Fatigue is a common complaint by workers, and almost 20% of workers report symptoms of fatigue. Especially for drivers, fatigue contributes significantly to transportation accidents. In addition to the increasing loss due to accidents, driving fatigue is also causing many financial losses worldwide. Fatigued driving is also experiencing by coal mining workers in Indonesia, especially operator workers. This study aims to obtain strategic determinants of fatigue from individual factors, occupational factors, and external factors for coal mining operators in Kalimantan and Sumatra in 2021. This study uses a cross-sectional design for two coal mining companies, seven mine sites, and 480 operators. Data collection was online using a questionnaire. Fatigue was measured using three instruments, namely the individual strength-20 checklist (CIS-20), the multidimensional fatigue inventory-20 (MFI-20), and the Swedish occupational fatigue inventory (SOFI). The types of fatigue studied included general fatigue, physical exhaustion, mental fatigue, and emotional exhaustion. Several standard instruments were used in this study, such as the perceived stress scale to measure stress, the Dutch boredom scale to measure boredom, and the Pittsburgh sleep quality index to measure sleep quality. Data analysis used chi-square and multiple logistic regression. Operators who became research respondents had an age of 32.13 ± SD 6.1 years (21 – 58 years), while the BMI obtained an average of 24.86 ± SD 3.1 with a range (16.51 – 33.75) and the highest BMI 24.22. There are 26.9% of operators included in the obese category. The majority of operators are married (85%), and most (63.5%) live outside the mess with their families (55.8%), and the majority (96%) have a high school education or equivalent. The average operators' tenure is 9.52 ± SD 4.2 years with a range (1-24 years), and the most tenure is ten years. Most of the operators work in the mining area (65.8%). The number of operators based on shift patterns and shift times is 240 (50%). The prevalence of fatigue in operators ranges from 20%-31%, with general fatigue 24.8%, physical fatigue 22.3%, mental fatigue 32.3%, and emotional fatigue 30.6%. The strategic determinants of operator fatigue consist of individual factors, including stress levels, sleep quality, external sleep disturbances, work factors including work locations in the mine, and external factors, namely living with family. The work shift pattern and working period are contextual factors. Factors that determine all types of fatigue are stress levels and work locations. The strategic determinants of general fatigue were stress level (OR=3.0), work location (OR=2.5), sleep quality (OR=1.8), and living with family (OR=1.6). On physical exhaustion, strategic determinants were stress level (OR=2.5), external sleep disturbance (OR=2.2), and work location in the mine (OR=1.7). Mental fatigue has strategic determinants, namely sleep quality (OR = 2.1), work location in the mine (OR = 2.1), stress level (OR = 1.7) and external sleep disturbances (OR = 1.6). Meanwhile, emotional exhaustion has strategic determinants, namely stress level (OR=2.0), work location (OR=1.9), and sleep quality (OR=1.9). Emotional fatigue has a shift pattern as a contextual factor with OR = 1.9 and job tenure with OR = 1.6. The conclusion is the determinants of fatigue in coal mine operators include individual factors, occupational factors, and an external factor. Mental fatigue is the type of fatigue most felt by operators. The determinants of fatigue found in all fatigue types are work sites and stress levels. All determinants might be accountable for developing fatigue policy and risk management programs at coal mining companies. Keywords: coal mining operator, fatigue, shift work, sleep quality, stress

Bahan kimia menimbulkan keterbahayaan pada lingkungan kerja dan pekerja itu sendiri. Oleh karena itu, pengelolaan dan pengamanan bahan kimia, harus dilakukan untuk melindungi pekerja dari efek yang merugikan. Pekerja harus mendapatkan perlindungan dari dampak yang diakibatkan oleh bahanbahan kimia di tempat kerja.
Laboratorium merupakan suatu tempat dimana banyak dilakukan kegiatan yang menggunakan bahan-bahan kimia. Potensi bahaya yang ditimbulkan antara lain bersifat toksik atau beracun, iritan, karsinogenik, korosif, mudah terbakar dan meledak.
Untuk mengetahui paparan bahan kimia di ternpat kerja, dalam hal ini merkuri, penulis melakukan penelitian dengan obyek penelitian adalah pekerja di Balai Laboratorium Kesehatan Bandar Lampung. Pengukuran kadar merkuri menggunakan spektrofotometri serapan atom, dengan spesimen yang diambil adalah rambut pekerja.
Hubungan paparan merkuri dengan kadar merkuri pada rambut pekerja laboratorium melibatkan variabel lamanya masa kerja, umur pekerja dan kadar merkuri diudara ruang kerja. Kadar merkuri pada rambut pekerja, dibandingkan dengan rata-rata tertinggi kadar merkuri di rambut pads komunitas yang dikeluarkan oleh WHO, yaitu sebesar 2,0 ppm.
Dari sejumlah 49 orang pekerja laboratorium, yang memenuhi kriteria sebagai sampel hanya 45 orang, dimana yang bekerja dibagian teknis sebanyak 29 orang, sedangkan yang bekerja dibagian non teknis sebanyak 16 orang.
Diperoleh hasil pengukuran kadar merkuri di udara ruang kerja laboratorium masih dibawah nilai ambang batas ( NAB ), tetapi paparan yang terus menerus akan mengakibatkan akumulasi merkuri didalam tubuh, walaupun konsentrasinya dibawah nilai ambang batas.
Hasil analisis bivariat terhadap variabel lamanya masa kerja, umur pekerja dan kadar merkuri diudara ruang kerja bagian teknis didapatkan hubungan yang signifikan antara variabel tersebut dengan kadar merkuri pada rambut pekerja.
Pada hasil akhir dari analisis regresi multivariate tidak didapatkan hubungan yang bermakna antara variabel dependent dan independent Hal ini disebabkan karena ukuran sampel yang kecil dan distribusi data penelitian yang tidak normal.
Chemicals agent can not be separated with human's life. The benefit of the materials is to increase public's welfare especially that is related to disease control, agricultural productivity, mineral extract in mining, household's necessity and so on.
Chemicals agent may endanger the workers, work environment_ Therefore, materials' management and safety must be carried out for the sake of workers' protection from side effect. The workers need to be protected from the effects that cause by the materials in their work places.
Laboratory is a place where many activities using chemicals agent are conducted. Harmful potentials are caused by toxic agents, irritant, carcinogenic, corrosive chemicals, flammable and explosives substances.
To know the exposured of chemical materials in the work places, especially mercury, the writer conducted a research where the laboratory personnel of Bandar Lampung Health Laboratory were the object of the research. The measurement of the mercury level was by using Atomic Absorption Spectrophotometry, and the specimen materials taken were personnel's hair.
The relationship of mercury's exposure to the level of mercury within the laboratory's personnel hair involved length of work variable, personnel's age and level of mercury within the air in the working room. Mercury's level within the and level of mercury within the air in the working room. Mercury's level within the workers' hair were compared with the highest average mercury level within the hair in the community, that issued by WHO is 2.0 part per million.
From 49 laboratory's personnel, those fulfill the sample's criteria were 45, who 29 of them worked in technical section, and 16 others worked in non-technical section.
The obtained result from the measurement of mercury level in the working room at the laboratory remained below Threshold Limit Value (TLV). However, continual mercury's exposure may result mercury accumulation within the body, though its concentration was below the TLV.
The result of bivariat analysis from the variables of length of work, workers' age, and mercury level within the air in the technical section working room showed that there was a significant relationship between the variables and mercury level within workers' hair.
On the final result from multivariate regression analysis, not be obtained fairly significant relationship between dependent and independent variables. This problems caused by sample size was so small and spreading for data was not proportional.
