Abstract

Background, Lead (Pb) constitutes as main pollutant in the air of the cities except sulphur dioxide (SO2), suspended particulate matter, nitrogen oxide (NOX ), and carbon monoxide (CO). The impacts of lead (Pb) exposure to health are kidney disorder, hypertension, anemia, central nerve disorder, behaviourial changes, fertility disorder, miscarriage, child’s IQ decrease, and the obstruction in the formation of hemoglobin. Objective, the description blood profile and nutrition status gas station workers   exposure in  the  easternt Semarang City. Method, the research is analytic observational uses cross sectional design with the number of samples 39 people. variable is  blood profile and the nutrition status. Results, the blood profile catch with the level of haemoglobin, leucosyt, hematocrit, erytrocite, MCV, MCH, MCHC, still in normal limits,  nutritional status most gas station workers the level normal. Conclusion, the no significant correlation  blood profile (haemoglobin, leucosyt, hematocrit, erytrocite, MCV, MCHC with nutrition status, the significant correlation blood profile (MCH) with nutrition status.  Suggestion, it is recommended that the gas station worker swear the self protective device (masker) while working in the gas station order to reduce the exposure of lead (Pb) from the motor vehicle exhaust and perform regular medical checkup with certain interval (at least once a year).Key words  :, blood profile, nutrition status,  gas attendants.

Abstract

Latar belakang: Air limbah rumah tangga yang belum terolah di wilayah Kelurahan Srondol Kulon Kecamatan Banyumanik Semarang pada pemeriksaan pendahuluan mempunyai nilai BOD 700,3 mg/l dan TSS 311 mg/l. Nilai ini menurut Keputusan Menteri Lingkungan Hidup No. KEP-51/MENLH/10/1995 tentang baku mutu limbah cair bagi kegiatan yang telah beroperasi, telah melebihi ambang batas yang diperbolehkan yaitu BOD maksimal 50-150 mg/l, TSS maksimal 200 mg/l. Kualitas air limbah mempunyai BOD dan TSS melebihi batas, akan berisiko menimbulkan dampak buruk kualitas lingkungan. Trickling filter merupakan salah satu pengolahan limbah cair secara biologis dengan memanfaatkan teknologi biofilm. Bahan yang digunakan sebagai media trickling filter harus kuat, keras, tahan tekanan, tahan lama, tidak mudah berubah dan tidak mudah menyumbat pada media trickling filter. Bahan yang biasa digunakan adalah batuan. Pada penelitian ini akan dicoba digunakan media filter berupa tempurung kelapa yang mempunyai sifat sesuai syarat media filter. Metode: Penelitian ini merupakan penelitian eksperiment semu dengan rancangan non randomized pretest-postest control group design. Sampel air limbah diambil dari saluran air limbah rumah tangga di Kelurahan Srondol Kulon Kecamatan Banyumanik Koa Semarang. Hasil: sebelum perlakuan (kontrol), BOD tertinggi 196,5 mg/l, terendah 121,6 mg/l. TSS tertinggi 222,4 mg/l, terendah 209,4 mg/l. suhu tertinggi 27,5ºC, terendah 27 ºC. pH semua sama yaitu 7. Setelah perlakuan rata-rata BOD tertinggi 112,68 mg/l, terendah 61,58 mg/l, rata-rata TSS tertinggi 129,8 mg/l, terendah 79,35 mg/l, suhu dan pH tidak mengalami perubahan. Prosentase penurunan BOD tertinggi 63,22%, terendah 39,94 %), prosentase penurunan TSS tertinggi 64,32 mg/l, terendah 41,32 %. Uji t untuk sampel berpasangan pada semua perlakuan didapatkan nilai p semua kurang dari 0,05, artinya ada perbedaan yang signifikan nilai BOD maupun TSS antara sebelum dan sesudah pengolahan. Untuk penurunan BOD pada berbagai lama waktu tinggal dan ketebalan media filter didapatkan nilai p=0,000 sedangkan pada TSS nilai p= 0,000 sehingga ada interaksi antara faktor lama waktu tinggal dan  ketebalan media filter pada penurunan BOD maupun TSS. Simpulan: ada perbedaan yang signifikan nilai BOD maupun TSS antara sebelum dan sesudah pengolahan, ada interaksi antara faktor lama waktu tinggal dan  ketebalan media filter pada penurunan BOD maupun TSS.

Abstract

Cigarettes contain more than 4000 elements and at least 200 of them are harmful to health. The main toxins in cigarettes are tar, nicotine, and carbon monoxide. The purpose of this study was to know the ability of coconut shell and durian skin activated carbon as adsorbent of carbon monoxide. The study was pre-experimental with Randomized control group only design. Independent variable is the type of activated carbon (coconut shell, durian skin, and contol), the dependent variable is the concentration of carbon monoxide. This is laboratory-scale research. The results showed the lowest concentration of carbon monoxide in the treatment with activated carbon durian skin that 29 ppm. The average of carbon monoxide concentration decrease (than the control group) on coconut shell group 68,7 ppm, while the average of durian skin is 77,478 ppm. One way anova test results to see the difference in the concentration of carbon monoxide in various types of activated carbon p value 0,000 while independent t test to see the difference carbon monoxide reduction between coconut shell and durian skin activated carbon with p value is 0,000. Conclusion: there is a differences adsorbtion of carbon monoxide between coconut shell and durian skin activated carbon.Keywords: carbon monoxide, activated carbon, coconut shell, durian skin
