The coke production process by baking semi-coke briquette in a coke’s bakingoven will produce flue gas and smoke. The same also happens in its utilizationtest in metal foundry kiln known as “tungkik” (plunging) smelting kiln. The gasand smoke predictably contain heavy metals and polluted chemical compoundsthat will pollute the environment and disturbing the health of workers if theirconcentrations pass over defined standard quality level. The objective of thisstudy is to examine the amount of heavy metals and chemical compoundpollutants produced in the process of baking semi-coke to produce coke and inthe utilization of coke as fuel in tungkik kilns. Measurement results show thatheavy metals in the kiln’s chimneys and chambers such as As, Cd, Pb, and Hgcould not actually be detected, while Fe, Na, Al, Ca, and K could be easilydetected. The concentrations of such metals are in the range of: Na = 100-315µg/m3, Al = 215-360 µg/m3, Ca = 786-1330 µg/m3, Fe = 478-2300 µg/m3, and K = 0.25-0.5 µg/m3. Meanwhile pollutants from other chemical compounds in the flue gas are NO2 = 80.7785-83.3725 mg/m3 and SO2 = 10.85-10.98 mg/m3. Pollutantsfrom ambient air are NO2 = 179.11-236.49 µg/Nm3, SO2 = 112.56-256.52 µg/Nm3,CO = 43.80-100.98 µg/Nm3, HC = 0.05-0.64 µg/Nm3, and O3 = 2.8098-19.6065µg/Nm3. The total particle’s content is also low, which is about 0.283 mg/m3 in thecoke baking oven’s chimneys, 0.554 mg/m3 in the tungkik kiln’s chimneys and0.259 mg/m3 in the metal melting locations. Comparison of the measurementresults with that of quality standard defined by the government regulation of theRepublic of Indonesia No.41 Year 1999 about air pollution control, show that theresults is far below the tolerated level. Therefore, the existence of coke bakingoven is still feasible and safe to the environment.Kata kunci: briket kokas, pencemaran lingkungan, logam berat

The quality of water in a river is affected by its natural condition and pollutant input originated from activities conducted around the river. In the Siak river, however, the black water effect influences thedistribution of the pollutant in general. To understand the quality of water in the black water affected by an area, a study was conducted from December 2015 to July 2016. The water was sampled during lowand high tides, in 8 sampling sites that were distributed along the river, from the mouth of the river in Siak Sri Indrapura Regency to upstream in Palas Village, Kampar Regency (around 180 km from the mouth ofthe river). The results showed that in the downstream of the Siak river, the quality of water during the low and high tides was worse than the 3rd Class Water Quality Standard issued by the Government Regulation (GR No. 82 / 2001) except for the concentration of nitrate, total coliform, Hg, oil and fat. The BOD was 14-39.2 mg/L (the high tide) and 17-45.6 mg/L (the low tide), COD was 51.76-80.62 mg/L (thehigh tide) and 51.76-69.12 mg/L (the low tide), NH3-N was 0.03-1.09 mg/L (the high tide) and 0.03-0.92 mg/L (the low tide), while the NO2-N was 0.13-0.17 mg/L (the high tide) and 0.13-0.22 mg/L (the low tide). Based on the Storet Index, the water of the downstream in the Siak river during the low and the high tide can be categorized as heavily polluted (score -52 to -70), and it tends to decline during the high tide.

PM2.5has gradually become a major environmental problem of China with its rapid economic development, urbanization, and increasing of motor vehicles. Findings and awareness of serious PM2.5pollution make the PM2.5a new criterion pollutant of the Chinese National Ambient Air Quality Standard (NAAQS) revised in 2012. The 2012 NAAQS sets the PM2.5concentrate limitation with the 24-hour average value and the annual mean value. Wuhan is quite typical among central and southern China in climate, economy, development level, and energy consumption. The data are cited from the official website of Wuhan Environmental Protection Bureau and cover the period from 1 January to 30 June 2013. The data definitely confirm the existence of serious PM2.5pollution in Wuhan and indicate that the addition of PM2.5as a criterion pollutant significantly brings down the attainment rate of air quality. The example of Wuhan reveals that local governments should take measures to reduce the emission of PM2.5if it affects the attainment rate and the performance evaluation value of air quality. The main contribution of 2012 NAAQS is that it brings down the attainment rate of the air quality and forces local governmental officials to take the measures accordingly.
