Abstract

Cigarettes contain more than 4.000 elements, at least 200 of them are harmful to health. The main toxins are tar, nicotine, and carbon monoxide (CO). The purpose study was to know ability of coconut shell and durian skin activated carbon as adsorbent of CO. The study was pre-experimental with randomized control group only design. Independent variables are types of activated carbon, the dependent variable is concentration of CO. The results showed the lowest  in durian skin activated carbon that 29 ppm. The average CO decreased on coconut shell is 68,7  ppm, durian skin is 77,478 ppm. One way anova test to see the difference CO in various of activated carbon p value 0,0001, independent t test to see the difference CO reduction  between 2 types activated carbon with p value is 0,0001. Conclusion: there is a differences adsorbtion of CO between coconut shell and durian skin activated carbon.

Abstract

Latar belakang: Polusi udara dalam ruangan menjadi masalah kesehatan yang lebih berat dibanding di luar ruangan. Salah satu sumber pencemar udara dalam ruangan adalah rokok. Rokok mengandung setidaknya 200 elemen berbahaya bagi kesehatan, tiga di antaranya yang paling berbahaya, yaitu tar, nikotin, dan karbon monoksida. Kadar CO dari asap rokok pada penelitian sebelumnya berkisar 109-113 ppm. Kadar ini masih di atas nilai ambang batas yang diperbolehkan yaitu 25 ppm. Untuk itu perlu upaya untuk mengurangi CO di udara. Penelitian sebelumnya menyimpulkan adsorben dan absorben terbaik dalam menurunkan CO adalah kaktus, jamur Penicillium sp, dan karbon aktif kulit durian. Tujuan penelitian untuk mengetahui perbedaan kemampuan adsorbsi dan absorbsi CO berdasarkan jumlah kaktus, jamur Penicillium sp, dan karbon aktif kulit durian.Metode: Jenis penelitian adalah eksperimen semu dengan rancangan static  group comparison. Obyek penelitian adalah  CO udara dalam ruangan, variabel penelitian adalah jumlah adsorben/absorben, jenis adsorben/absorben, dan konsentrasi CO di udara. Pengukuran CO dengan CO meter digital. Analisis data dengan uji anova 1 arah dan uji kruskal wallis dengan tingkat kemaknaan 95%.Hasil: rata-rata CO dengan kaktus 1 batang 63 ppm, 2 batang 56 ppm, 3 batang 46,6 ppm, 4 batang 28 ppm, dan kontrol 106,6 ppm. Rata-rata CO dengan Penicillium sp 150 gram 47,3 ppm, 300 gram 34,7 ppm,  dan kontrol 76,6 ppm. Konsentrasi CO dengan karbon aktif kulit durian 1 kg 41,56 ppm, 2 kg 30,89 ppm, dan kontrol 101,4 ppm. Rata-rata CO dengan gabungan semua adsorben adalah 22,9 ppm. Uji perbedaan konsentrasi CO pada berbagai jumlah kaktus nilai p= 0,001, jamur penicilium sp nilai p=0,001, dan uji kruskall wallis  untuk karbon aktif kulit durian adalah 0,001.Simpulan: Ada perbedaan kemampuan adsorbsi dan absorbsi CO berdasarkan jumlah adsorben dan absorben. Jumlah kaktus terbaik adalah 4 batang, jamur Penicillium 300 gram, dan karbon aktif 2 kg. Konsentrasi CO dengan penggabungan semua adsorben dan absorben telah berada di bawah nilai ambang batas yang diperbolehkan yaitu 25 ppm.ABSTRACTTitle: The Effectiveness of Ornamental Plants, Fungi, and Activated Carbon in Reducing Carbon Monoxide Concentrations in the AirBackground: Cigarettes contain about 4000 elements and 200 of them are harmful to health. Exposure to cigarette smoke which is quite potential is CO. CO is a toxic gas and is one of the greenhouse gases that damage the earth's ozone layer. Exposure to cigarettes in the room is still widely found. Need to attempt to reduce CO in the air. Previous research concluded that the best type of adsorbent in lowering CO is cactus, Penicilliumsp, and durian skin activated carbon. The aim of this study isto know the difference in CO adsorption ability based on the number of adsorbents. Method: This research type is quasi-experimental with static group comparison design, the object is CO in the room, the variable is the amount of adsorbent, the type of adsorbent, the concentration of CO in the air. Data analysis used 1-way ANOVA test and Kruskalwallis test. Results: on average CO with cactus 1 stem 63 ppm, 2 stems 56 ppm, 3 stems is 46.6 ppm, 4 stems is 28 ppm, and control is 106.6 ppm. The average CO with Penicilliumsp 150 grams is 47.3 ppm, 300 grams is 34.7 ppm, and control is 76.6 ppm. The average CO with 1 kg durian skin activated carbon is 41.56 ppm, 2 kg is 30.89 ppm, and control is 101.4 ppm. The average CO with a combination of all adsorbents is 22.9 ppm. Test the difference in CO concentration in various cactus, pvalues = 0.001, Peniciliumsp p value = 0.001, and the Kruskal wallis test for activated carbon was 0.001. Conclusion: There are differences in CO adsorption and absorption based on the number of cactus, Peniciliium sp, and durian skin activated carbon. The best amount of cactus is 4 stems, 300 grams of Penicillium sp, and 2 kg of activated carbon. CO concentration with all of adsorbent and absorbents has been below the permissible threshold value of 25 ppm.

Abstract

ABSTRACT Background, Lead (Pb) constitutes as main pollutant in the air of the cities besides the pollution of  sulphur dioxide (SO2), suspended particulate matte (SPM)r, nitrogen oxide (NOX ), and carbon monoxide (CO). The impacts of lead (Pb) exposure on  health are kidney disorder, hypertension, anemia, central nerve disorder, behaviourial changes, fertility disorder, miscarriage, child’s IQ decrease, and the disorder  in formation of hemoglobin. Objective, to find out the correlation between the level of lead (Pb) exposure and the blood profile’s of  gas station workers located in the eastern part of  Semarang City. Method, the research used a  cross sectional design with the number of samples were  39 worker. Independent variable was the level of lead content in blood, while the dependent variable was  blood profile and confounding variables were  health history,  intake of energy and  protein , vitamin B12 , folic acid , vitamin C , the habit of drinking tea, drug use, use of self protective device, smoking habit, and alcohol consumption. Results, the average of blood lead  concentration were measured  13,35 µg/dl, the blood profile that including  the level of haemoglobin, leucocyte, hematocrit, erytrocite, MCV, MCH, MCHC, still in normal limits,  variable of blood lead concentration had significant correlation with the level of hemoglobin and the level of hematocrit,  with  OR = 1,388; 95 %  CI=  1,094 – 1,761  for haemoglobin and OR= 1,358 ; 95 %  CI= 1,095 – 1,685  for  hematocrit respectively. Conclusion, the level of  lead content in  blood which is above normal act as  risk factor of decreasing the level of hemoglobin and hematocrit by 1,388 times and 1,58 times respectively, compared with that of normal level of lead content in the blood.  It is recommended that the gas station worker wear the self protective devices (masker) while working in the gas station in  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 lead content, blood profile, gas attendants.
