Abstract

ABSTRAKStudi paparan konsentrasi gas karbonmonoksida (CO) terhadap petugas parkir dan polisi lalu lintas bertujuan untuk mengetahui tingkat paparan yang diterima di udara tempat kerjanya dan melihat beberapa variabel yang mempengaruhi konsentrasi gas CO. Penelitian ini dilakukan di areal parkir tertutup di pusat perbelanjaan terbesar Kota Padang (Plaza Andalas dan Rocky Plaza Hotel) dan di 5 pos jaga Polisi Lalu Lintas. Pengukuran gas CO dilakukan dengan menggunakan CO meter dengan electrochemical sensor dan dioperasikan selama 1 jam di setiap titik pengukuran. Pengukuran CO di areal parkir tertutup menunjukkan bahwa konsentrasi CO di udara kerja petugas parkir Plaza Andalas dan Rocky Plaza Hotel melebihi batas baku mutu, sementara jumlah kendaraan yang mengkontribusi gas selama pengukuran di areal parkir memiliki hubungan yang kurang kuat(R2=6,5%-51%) terhadap peningkatan konsentrasi CO. Sedangkan dari hasil pengukuran gas CO di 5 pos jaga polisi lalu lintas menggambarkan bahwa konsentrasi CO masih berada di bawah baku mutu, dan volume lalu lintas sebagai variabel bebas yang diduga berpengaruh memiliki hubungan yang kurang kuat (R2=45%) terhadap peningkatan gas CO di udara tempat kerja Polisi Lalu Lintas.Kata kunci: Gas karbonmonoksida (CO), petugas parkir, polisi lalu lintas, CO meter.ABSTRACTStudy of carbon monoxide concentration (CO) of the parking attendants and traffic police checkpoints aimed to determine acceptable levels of exposure in the workplace area and to see some of variables that affect the concentration of CO. The research was carried out in the parking lots of Padang's largest shopping center (Plaza Andalas and Rocky Plaza Hotel) and in 5 traffic police checkpoints. CO measurements were carried out using a CO meter with an electrochemical sensor and operated for 1 hour at each measurement point.

Abstract

The traditional market area in Padang City is an area with a fairly high transportation activity of motor vehicles. The aims of this study is to determine the air quality for CO parameter due to motor vehicles in Padang City. The measurement of CO concentration was conducted in the traditional markets in Padang City which were located near the highway, namely Bandar Bandar Market, Pasar Raya Padang Market and Lubuk Buaya Market to see the effect of motor vehicle on transportation activity. CO measurements were carried out using CO meters for one hour during peak hours (07.00-08.00, except for Pasar Raya Market, conducted at 16.00-17.00) and off-peak hours (10.00-11.00 wib). CO concentrations during peak hours range between 5.92 and 11.67 ppm, while in the off-peak hours between 4.58 and 9.25 ppm. The outside of the traditional market (8.50-11.67 ppm) which is located on the edge of the highway, has a higher CO concentration than the inside (4.58-5.92 ppm). The measured CO concentrations in each location are below the national air quality standards. It means, the presence of traffic flow in the traditional market area in Padang City affects air quality on the edge of the highway, but not so affect the air quality in the inside area in the traditional market.Keywords: Transportation, Motor Vehicle, CO Concentration, Traditional Market.ABSTRAKKawasan pasar tradisional Kota Padang merupakan kawasan dengan aktivitas transportasi kendaraan bermotor yang cukup tinggi. Penelitian ini bertujuan untuk mengetahui kualitas udara untuk parameter CO akibat kendaraan bermotor di Kota Padang. Pengukuran konsentrasi CO dilakukan di pasar tradisional di Kota Padang yang berada dekat jalan raya, yaitu Pasar Bandar Buat, Pasar Raya Padang dan Pasar Lubuk Buaya untuk melihat pengaruhnya dari aktivitas transportasi kendaraan bermotor. Pengukuran CO dilakukan menggunakan CO meter selama satu jam pada jam sibuk (07.00-08.00 wib, kecuali untuk Pasar raya Padang, dilakukan pukul 16.00-17.00 wib) dan jam senggang (10.00-11.00 wib). Konsentrasi CO saat jam sibuk berkisar 5,92–11,67 ppm, sedangkan pada jam senggang sebesar 4,58 – 9,25 ppm. Bagian luar pasar tradisional (8,50–11,67 ppm) memiliki konsentrasi CO lebih tinggi dari pada bagian dalamnya (4,58-5,92 ppm). Konsentrasi CO terukur di setiap lokasi masih berada di bawah baku mutu. Artinya, adanya arus lalu lintas di kawasan pasar tradisional di Kota Padang mempengaruhi kualitas udara pada pinggir jalan raya, tetapi tidak begitu mempengaruhi kualitas udara di kawasan dalam pasar tradisonal tersebut.Kata kunci: Transportasi, Kendaraan Bermotor, Konsentrasi CO, Pasar tradisional.

Abstract

This study examines the resilience variables of urban Drinking Water Supply Systems (WSS) in responding to floods, with a focus on West Sumatra Province, Indonesia, using the Fuzzy Delphi Method (FDM). The study identifies three main resilience properties: robustness, recovery, and learning, within a temporal framework. Thirteen sub-properties and 41 indicators were validated using FDM by 10 experts in fields relevant to the research topic. As a result, 12 sub-properties were accepted by expert consensus, while one sub-property, namely governmental situation awareness, was rejected because all three of its indicators failed to meet the validation criteria. A total of 33 out of 41 indicators were considered significant, relevant, and useful by the expert panel. Furthermore, the findings emphasize the critical role of the governmental dimension in determining the resilience level of SPAM in West Sumatra Province. These results will serve as a guide for policymakers in prioritizing resilience-based decisions to mitigate flood threats.

Abstract

Air pollution is one of the most pressing environmental issues, with direct impacts on human health and environmental quality. The increasing intensity of transportation activities, industrial operations, forest and land fires, and regional development in South Sumatra Province has increased the risk of air pollution, particularly from nitrogen dioxide (NO2) and sulfur dioxide (SO2). This study aims to analyze the concentrations and multi-year trends of NO2 and SO2 in South Sumatra based on passive sampler measurements conducted at 68 monitoring sites across 17 districts and municipalities during the period 2021–2024. The results show that the average concentrations of NO2 ranged from 6.654 to 9.944 micrograms per cubic meter, while SO2 concentrations ranged from 7.303 to 8.456 micrograms per cubic meter. All measured concentrations were below the National Ambient Air Quality Standards as well as the European Union guideline values. Trend analysis indicates a consistent decrease in NO2 and SO2 concentrations from 2021 to 2024. These findings contribute to the availability of long-term air quality data and enhance understanding of NO2 and SO2 dynamics, providing a scientific basis for the development of evidence-based strategies for air pollution control and prevention in South Sumatra Province. Keywords: nitrogen dioxide, sulfur dioxide, passive sampler, South Sumatra, air pollution trends.
