Penarik becak dayung dan becak bermesin, pengatur lalu lintas, pedagang asongan, dan pedagang kaki lima banyak terpapar dengan polusi timbal dari udara ambien yang merupakan ancaman terhadap para pekerja pinggir jalan. Penelitian ini bertujuan mengetahui hubungan karakteristik responden dengan kadar timbal dalam darah. Sampel dalam penelitian ini berjumlah 109 orang terdiri dari 58 orang penarik becak dayung, 30 orang penarik becak bermesin dan 21 orang pedagang kaki lima yang ditarik secara consecutive sampling. Hasil penelitian menunjukkan bahwa tidak ada korelasi yang signifikan antara variabel usia, tekanan darah sistolik dan tekanan darah diastolik terhadap kadar timbal dalam darah (p>0,05). Rerata kadar timbal dalam darah berbeda bermakna menurut jenis kelamin (p=0,047) dan kebiasaan merokok (p=0,003). Rerata kadar timbal dalam darah berdasarkan jenis pekerjaan, lama bekerja, tingkat pendidikan, tempat beristirahat, lokasi tempat tinggal, kebiasaan minum susu, dan kebiasaan minum alkohol tidak ada perbedaan bermakna. Uji korelasi Pearson dan korelasi Spearman menemukan tidak ada korelasi antara variabel usia dan tekanan darah terhadap kadar timbal dalam darah (p>0,05).Paddle rickshaw puller, motorized rickshaw pullers, traffic police, street vendors and roadside vendors is that many workers are exposed to lead from ambient air pollution. Lead pollution is a threat to roadside workers. This study is observational. The purpose of the study was to determine the association between respondent characteristic with blood lead levels. The 109 samples in this study was the 58 paddle rickshaw puller, 30 motorized rickshaw pullers and 21 hawkers, drawn with consecutive sampling. The results showed that there were no significant correlation between age, blood pressure and blood lead level (p>0.005), there were differences in mean blood lead levels by sex (p = 0.047) and smoking (p = 0.003), there was no difference in mean blood lead levels based on the type of work, length of work, level of education, place of rest, the location shelter, drinking milk, and alcohol drinking habits. Pearson correlation test and Spearman correlation found no correlation between the variables of age, and blood pressure on blood lead levels (p> 0.05).

Latar belakang : Hidrogen Sulfida (H2S) merupakan gas yang tidak mudah terbakar, tidak berwarna dan berbau seperti telur busuk dan masuk ke tubuh manusia terutama melalui udara yang dihirup. Paparan konsentrasi rendah Hidrogen Sulfida (H2S) dapat menyebabkan iritasi pada mata, hidung, atau tenggorokan. Penelitian ini bertujuan untuk mengetahui pengaruh pajanan gas Hidrogen Sulfida (H2S) terhadap keluhan saluran pernafasan pada pemulung, di TPA Ganet Kota Tanjungpinang.Metode : Jenis penelitian ini adalah survei bersifat analitik deskriptif  dengan desain cross sectional. Sampel dalam penelitian ini yaitu pemulung yang pekerjaannya hanya sebagai pemulung dengan lama bekerja ≥ 3 tahun  dan durasi terpapar  ≥ 40 jam/minggu dengan jumlah sampel memenuhi syarat 27 pemulung.Hasil : Berdasarkan uji statistik dengan Fisher,s Exact Test diketahui ada pengaruh jenis kelamin (p = 0,019 PR = 1,9) dan intake (p = 0,039 PR = 2,1) terhadap keluhan saluran pernafasan. Variabel yang paling berpengaruh dominan pada uji regresi logistik antara jenis kelamin, konsentrasi H2S dan intake terhadap keluhan saluran pernafasan pada pemulung di TPA Ganet Tahun 2018 yaitu jenis kelamin dan intake dengan probabilitas 97,9 %.Simpulan : Ada pengaruh yang signifikan antara jenis kelamin dan intake dengan keluhan saluran pernafasan pada pemulung di TPA Ganet Kota Tanjungpinang. ABSTRACTTitle: The Effect of Exposure Hydrogen Sulfide Gas (H2S) on the Complaints of Respiratory Track in Scavengers at the Ganet’s Final Waste Disposal of Tanjungpinang 2018Background : Hydrogen Sulfide (H2S) is a gas that is not flammable, colorless and smells like rotten eggs and enters the human body primarily through inhaled air. Exposure on low concentrations of Hydrogen Sulfide (H2S) can cause irritation to the eyes, nose or throat. This study aims to determine the effect of exposure to Hydrogen Sulfide (H2S) gas the respiratory tract complaints in scavengers at the Ganet’s final waste disposal of Tanjungpinang.Methods : This type of research is a descriptive analytic survey with a cross sectional design. The samples in this study were scavengers whose works were only as scavengers with length of work ≥ 3 years and duration of exposure ≥ 40 hours / week with the number of samples fulfilling the requirements of 27 scavengers.Results : Based on the statistical test with Fisher,s Exact Test it is  found that there was influence of sex (p = 0.019 PR = 1.9) and intake (p = 0.039 PR = 2.1) on respiratory complaints. The most dominant variable influenced the logistic regression test between gender, H2S concentration and intake of respiratory tract complaints on scavengers in 2018 TPA Ganet, were gender and intakes with a probability of 97.9%.Conclusion : There is a significant influence between gender and intake with complaints of respiratory tract on scavengers in TPA Ganet, Tanjungpinang City.

<p>Poor landfill management and not in accordance with the rules raises serious problems of liquid waste (leachate). One alternative treatment of heavy metal contaminated waste is phytoremediation techniques with aquatic plants. The purpose of this study was to determine the effect of growth on Typha Latifolia test plants using leachate concentrations. The study used the concentration method for diluting V1.N1 = V2.N2 and Regression. The leachate concentrations used were 20%, 40%, 60%, 80% and 100% and control. Observation data focused on the number of tillers, root length, leaf length and number of leaf petals. The results obtained from the observation data the higher the leachate concentration, the lower the number of tillers, root length, number of leaves and number of leaf petals in Typha latifolia test plants. This proves that Typha latifolia plants are hyperaccumulator plants that can grow on leachate.</p>

<p>WHO (World Health Organization) mentions that water quality is biologically determined by the presence of E. coli bacteria. The content of E.Coli bacteria allowed in drinking water is 0 per 100 ml of sample. Sugar cane juice is one of the most E.Coli contaminated beverages. E. coli can cause disease associated with digestion such as diarrhea and including urinary tract infections, gastroenteritis, meningitis, peritonitis, and wound infections. The purpose of this study was to analyze the relationship of sanitary hygiene of vendors and environment with Escherichia coli content in sugar cane juice. The research was an analytic research using cross-sectional design approach. The sample of this study was 30 sugar cane vendors around Medan city. Data analysis using Pearson and linear regression test. Measurement aspects were sugar cane processing,  transportation, sugar cane storage, sugarcane transportation and serving of sugar cane juice. The results showed a significant relationship between processing (p=0,00), location (p=0,02), transportation (p=0,00) and serving (p=0,00) with the present of E.Coli on sugarcane.  It is suggested to the government conducting supervision and educates the sugarcane vendors to prepare their products based on regulation of the District Health Office.</p>
