ABSTRAKSungai Cikijing termasuk ke dalam Sub DAS Citarik melintasi dua wilayah administrasi yaitu Kabupaten Sumedang dan Kabupaten Bandung. Sungai Cikijing menjadi sarana pembuangan air limbah dari aktivitas industri sehingga berpotensi menimbulkan pencemaran air sungai. Tujuan dilaksanakannya penelitian ini adalah menganalisis dampak pembuangan air limbah PT. X terhadap 3 aspek yaitu budidaya, kualitas air tanah dan tanah serta kesehatan masyarakat berdasarkan Peraturan Pemerintah Republik Indonesia Nomor 82 Tahun 2001. Kualitas air Sungai Cikijing pada Bulan Januari dan Agustus 2017 mengandung parameter yang tidak memenuhi bakumutu yaitu TSS, TDS, BOD, COD, Detergen MBAS, Belerang (H2S), Minyak dan Lemak, Nitrit, Nitrat dan Fenol. Pencemaran yang terjadi di Sungai Cikijing tidak berpengaruh terhadap penurunan kesuburan tanah, karena air Sungai Cikijing tidak dijadikan sumber air irigasi untuk lahan pertanian di lokasi sampling. Analisis kualitas air bersih di lokasi studi diambil dari 2 lokasi dengan membandingkan bakumutu sesuai Permenkes RI No. 492 Tahun 2010. Parameter air sumur di Desa Linggar yang tidak memenuhi bakumutu yaitu kekeruhan, Fe, Mn, dan Zat Organik (KmnO4). Sedangkan di Desa Jelegong parameter kekeruhan, pH, Fe, Mn, dan Zat Organik (KmnO4) tidak memenuhi baku mutu. Kualitas air sumur di kedua lokasi titik pemantauan tidak layak untuk di konsumsi harus dilakukan pengolahan terlebih dahulu sebelum dipergunakan untuk kebutuhan sehari-hari. Sungai Cikijing yang sudah tercemar dikhawatirkan dapat menurunkan kesehatan masyarakat. Data kesehatan masyarakat diperoleh dari Puskesmas Cisempur, Puskesmas Sawah Dadap, dan Puskesmas Rancaekek tahun 2015-2016 menunjukkan bahwa penyakit yang banyak diderita oleh masyarakat bukan sebagai akibat dari pencemaran air sungai Cikijing.Kata Kunci: Sungai Cikijing, Industri, PencemaranABSTRACTCikijing River is part of Citarik Sub watershed over two administrative areas of Sumedang and Bandung regencies. Cikijing river become a discharge media by industrial activity and thus potentially cause pollution of river water. The purpose of this research is to analyze the impact of waste disposal of PT. X against 3 aspects ie cultivation, groundwater and soil quality and public health based on Government Regulation of the Republic of Indonesia Number 82 Year 2001. Cikijing River water quality in January and August 2017 contains parameters that do not meet stream standard these are TSS, TDS, BOD, COD, detergents MBAs, sulfur (H2S), oil and fat, nitrite, nitrate, and phenol. Pollution that occurred in the Cikijing River has no effect on the decline in soil fertility because the Cikijing River water is not used as a source of irrigation water for agricultural land in the sampling location. The analysis of clean water quality in the study sites was taken from 2 locations by comparing standard according to Permenkes RI. 492 of 2010. Water well parameters in Linggar village that do not meet the standard these are turbidity, Fe, Mn, and organic substances (KmnO4). While in Jelegong Village, turbidity, pH, Fe, Mn, and organic (KmnO4) parameters did not meet the quality standard. The quality of the well water at both sites of the monitoring point is not feasible for consumption should be processed first before being used for daily needs. The polluted Cikijing River is feared to reduce public health. Public health data obtained from government public health facilities in Cisempur, Sawah Dadap, and Rancaekek in the year 2015-2016 show that the disease suffered by many people, not as a result of water pollution Cikijing river.Keywords: Cikijing River, Industry, Pollution

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

This study aims to map the concentration of carbon monoxide (CO) in Medan city and to estimate the potential reduction in carbon monoxide in some streets of Medan by applying mass transit based on simulation. This research was conducted by sampling CO in the 12 (twelve) points in Medan by grab sampling. CO concentration was analyzed using NDIR methods by CO Monitor tools. The results showed the concentration of CO in Medan between 1145.2 mg/m3 - 27484,7 mg/m3. This condition is still below the national ambient air quality standard of Government Regulation No. 41, 1999 (30,000 mg/m3). Based on the concentration isophlet map that points that have the highest concentration located in the surrounding roadside such as at Jl. SM Raja. To reduction the CO concentration in the ambient air around the roadside is necessary to plan programs and policies related to transportation. If the scenarios or simulation with application of the concept of mass transportation such as BRT CNG and BRT Diesel in some streets of Medan then will be able to reduce CO emissions of about 25.02% to 29.44%.Keywords: vehicle emissions, carbon monoxide, map isophlet, mass transitABSTRAKPenelitian ini bertujuan untuk memetakan konsentrasi gas karbon monoksida (CO) di Kota Medan dan melakukan estimasi potensi penurunan karbon monoksida di beberapa ruas jalan Kota Medan dengan menerapkan transportasi massal berbasis simulasi. Penelitian ini dilakukan dengan pengambilan sampel CO di 12 (dua belas) titik di Kota Medan secara grab sampling. Konsentrasi CO dianalisis menggunakan metode NDIR dengan alat sampling yaitu CO Monitor. Hasil penelitian menunjukkan konsentrasi CO di Kota Medan antara 1145,2 mg/m3 27484,7mg/m3. Kondisi ini masih dibawah baku mutu udara ambien nasional Peraturan Pemerintah No. 41 tahun 1999 (30.000 mg/m3). Berdasarkan peta isophlet konsentrasi tersebut bahwa titik-titik yang mempunyai konsentrasi tertinggi berlokasi di sekitar jalan salah satunya seperti di Jl. SM Raja.

Konsentrasi PM10 dengan AERMOD berkisar antara 3,5 sampai 68,0 µg/m3 dengan rata-rata 24 jam sebesar 10,6 µg/m3. Jika dibandingkan dengan baku mutu untuk Peraturan Pemerintah No. 22 Tahun 2021 tentang Penyelenggaraan Perlindungan dan Pengelolaan Lingkungan Hidup, lokasi 11 dengan koordinat S 0°56'52.46" dan E 100°27'41.88"  pada  jarak 1 km kawasan Barat PT Semen Padang tidak memenuhi baku mutu. Model mendekati ideal atau dikatakan sempurna yaitu lokasi arah Timur dan Timur Laut karena elevasi yang lebih tinggi dari sumber emisi dan merupakan arah angin dominan pada siang hari.ABSTRACTThis study aims to test the AERMOD model in predicting the distribution of PM10 in the ambient air of the PT Semen Padang area. The research locations were 32 points based on eight cardinal directions with a radius of 0.5 km, 1 km, 1.5 km, and 2 km from PT Semen Padang. PM10 measurement using EPAM 5000 Real-Time Particulate Air Monitor followed by mapping with Surfer 11 software. The measurement time is divided into four shifts, namely shift 1 (00.00 – 05.59 WIB), shift 2 (06.00 – 11.59 WIB), shift 3 (12.00 – 17.59 WIB), and shift 4 (18.00 – 23.59 WIB). Meteorological data retrieval (air temperature, air pressure, humidity, wind speed and wind direction) using the Meteorological Station PCE-FWS-20 for data input to AERMET, followed by prediction of PM10 distribution using AERMOD View 8.9.0 software. The results showed that the concentration of PM10 with EPAM 5000 ranged from 21.0 – 79.0 g/m3 with a 24-hour average of 41.7 g/m3. The concentration of PM10 with AERMOD ranged from 3.5 - 68.0 g/m3 with a 24-hour average of 10.6 g/m3. When compared with the quality standard for Government Regulation no. 22 of 2021 concerning the Implementation of Environmental Protection and Management, location 11 with coordinates S 0°56'52.46" and E 100°27'41.88" at a distance of 1 km west of PT Semen Padang does not meet the quality standards. The model is close to ideal or is said to be perfect, namely the location of the East and Northeast directions because of the higher elevation of the emission source and the dominant wind direction during the day.
