Abstract

The present study investigate the feasibility of absorption chiller utilization as part of trigeneration system that possibly applied in sub-tropical country building. Trigeneration is refer to the heat utilisation from electric generator (combined heat and power, CHP) to generate absorption chiller in order to produce chilled water for air conditioning system (combined cooling, heat and power, CCHP). Compare to the vapour compression system, absorption chiller that is mainly generated by heat waste, promised benefit economically and environmentally. Overall efficiency of CCHP can reach 71 % and possibly reducing emission until 146709.07 kg CO2. Economic analysis using the Payback period methodology has shown that the CCHP would produce a return on investment of 2.6 years. Improvements absorption chiller and support from government are expected to lead to increased return on investment and improved viability of the system.

Abstract

North Bandung is an area where there are several tourist attractions, including the Dago Dream Park. The main road to several locations in North Bandung is via the road in front of Terminal Dago. For this reason, the purpose of this study was to collect data on PM2.5 and PM10 concentrations at both locations, namely in front of Terminal Dago and Dago Dream Park. Data collection was carried out for seven days, from Monday to Sunday, from 08.00 to 16.00 local time. To evaluate air quality in these two places, the national standard, namely PPRI No. 22 of 2021 and international standards from WHO were applied. The measurement results show that the concentrations of PM2.5 and PM10 in these two locations are still within the national standard. Meanwhile, when evaluated with WHO standards, PM10 concentrations in both locations are still within standard, but for PM2.5, there are several days where the air quality is out of the standard. The average concentrations of PM2.5 and PM10 during the 7 days of measurement at Terminal Dago are 19.9 μg/m3 and 21.6 μg/m3, respectively. While the average concentration of PM2.5 and PM10 during 1 week of data collection were 18.9 μg/m3 and 19.9 μg/m3, respectively. This means that the concentration of PM2.5 and PM10 at Terminal Dago is slightly higher than that of at Dago Dream Park. In addition, based on an evaluation using national standards, Dago Dream Park tourist attractions still have good air quality and are safe for local residents and tourists. From the data recorded at the Health Centre (Puskesmas), the number of ARI cases in the two locations in 2020 and 2021 is relatively not much different.

Abstract

The processing of limestone through the combustion process will cause air pollution at the combustion site and its surroundings. At the limestone processing site, Padalarang experiences relatively high air pollution. PM2.5 is one of the main pollutants produced by limestone burning, so it is very necessary to study the concentration of PM2.5 in the air in Padalarang and its surroundings. This study was conducted in Padalarang and its surroundings, where data collection was carried out in five locations, namely at the center of limestone burner, 1 km, 2 km, 3 km, and 4 km to the east of the burning center. Data collection was carried out for ten days, where each data collection was carried out for 12 hours, from 07.00 to 19.00. Based on the national standard of PPRI No. 22 of 2021, which is 55 µg/m3, the concentration in the limestone burning center and 1 km from burning center have exceeded the standard, which is 82.5 and 69.3 µg/m3. While PM2.5 concentrations at distances of 2 km, 3 km, and 4 km are below the national standard, namely 52.0, 51.6 and 50.2 µg/m3, respectively. Based on the Air Quality Index (AQI), the AQI at the burning center, distance of 1 km, 2 km, 3 km, and 4 km are Unhealthy, Unhealthy, Moderate, Moderate and Moderate, respectively. This means that areas less than 1 km away are not healthy places to live. The poor air quality in Padalarang is reflected in the much higher number of ARI cases compared to the surrounding sub-districts that do not have a limestone industry.

Abstract

Kota Baru Parahyangan is located between Cimahi City and Padalarang. As an area designed as a satellite city, Kota Baru Parahyangan has various facilities including a business centre. In the present study, PM10 and PM2.5 will be measured at three business centres and one residential location located at the southernmost point for comparison. Data collection was carried out on 2 weekdays, namely Monday and Tuesday, and 2 weekends, namely Saturday and Sunday. The data collection time is from 08:00 to 15:30, where data collection is carried out every 30 minutes. Based on these measurements, PM10 and PM2.5 concentrations in three business centre locations and 1 residential location are still under the PPRI No. 22 of 2021 standards. Meanwhile, when evaluated using Kepmen LHK No. 14 of 2020, the API level for PM10 in three business centre locations and 1 residential location is in the "Good" category. However, the API level for PM2.5 in three business centre locations and 1 residential has reached the "Moderate" category. This means that the concentration of PM2.5 in business centre and residential in Kota Baru Parahyangan should be seriously considered by developer and local government. Because it is confirmed that PM2.5 concentrations will continue to increase over time with increasing activity and an increase in the number of vehicles passing through a region.
