Abstract

During the Covid-19 pandemic, the number of visitor at the trade center in Bandung was much reduced as compared to before pandemic, which was only about 30% of normal conditions. The present study is to investigate particulate concentrations of PM2.5 and PM10 in three supermarkets in Bandung, namely Kosambi, Batununggal Modern and Cinunuk supermarkets during the pandemic of Covid-19. Air sampling was measured using a particulate counter CEM DT96 for 11 hours, from 06:00 AM to 5:00 PM, local time. The results showed that the average of outdoor and indoor concentrations of PM10 in two supermarkets (Batununggal Modern and Griya Cinunuk) was lower than standard during that 11 hours. As for the outdoor concentrations of PM2.5, both markets exceeded the standard for several hours in the morning. In general, it can be concluded that the outdoor and indoor concentrations of PM2.5 and PM.10 during pandemic were below the standard, except in the morning before 10:00 AM

Abstract

Sick building syndrome (SBS) is a collection of symptoms experienced by buildings occupants such as headaches, mucous, membrane irritation, respiratory problems and fatigue. A building is claimed to have SBS if more than 20% of building occupants experience symptoms. Poor indoor air quality contributes to SBS in the building. This study aims to investigate the correlation between indoor air quality and SBS symptoms in 1st and 2nd floors of the Post office building in Bandung. The study used quantitative methods with a cross sectional study design. Data collection was carried out using particle counter, thermometer, lux meter and anemometer to measure the indoor air quality, while the questionnaire utilized random sampling technique with 119 respondents. The results of the primary data were compared with the air quality standard from Minister of Health No. 1077, 2021. The results of the Statically Compare Means and Independent T-test showed that the p-values of the temperature on the 1st floor and 2nd floors were 0.437 and 0.000, respectively. Meanwhile the p-values of PM10 and PM2.5 on the 1st and 2nd floors were 0.005 and 0.290 and 0.004 and 0.364, respectively, and the p-values of the lighting on the 1st and 2nd floors were 0.002 and 0.015. It indicates that there is a significant relationship between concentrations of PM10 and PM2.5 on the 1st floor with SBS symptoms and the temperature and humidity on the 2nd with SBS symptoms. Since 29 peoples (24% of the building’s occupants) experienced SBS, the building was considered to have a significant potential to cause SBS to its occupant.

Abstract

During operation, the evaporator of split-type air conditioner (A/C) produces condensate water due to lower evaporator temperature, as compared to dew point temperature of the indoor air. So far, the condensate is considered unimportant and therefore being wasted. The split-type A/C is widely used in high-rise buildings, hotels, shopping areas, and even residential. The study aims to investigate the potential feasibility of the condensate to be used as for drinking water. Of course, treatment of the condensate is required before it can be used as a drinking water. The experiments were carried out in two cities, namely Bandung and Cirebon. Bandung represents a city with a cool climate, while Cirebon represents a city with a hot climate. The capacities of the A/C utilized in Bandung and Cirebon are 0.5 HP and 1 HP, respectively. The quantities of the condensate from the A/C were collected for 24 for hours. The quality of the condensate was benchmarked with guidelines/standard from PERMENKES NO 492/MENKES/PER/IV/2010. The benchmarking process involved testing and evaluation of 22 significant parameters related to water quality for drinking purpose. By utilizing waste condensate water, it is predicted that it can be a vital alternative of potable water in the future

Abstract

The role of the pump in any pumping system is to provide sufficient pressure to overcome the operating pressure of the system in order to move fluid (water) at a required flow rate to the user. In this study, a mathematics model was used for design in order to provide adequate water supply to every quarter in Federal Polytechnic Mubi, Adamawa state Nigeria. According to the research, the proposed water supply requires a 1360W power pump, a 1500W inverter, and a 1500W solar panel. Because the suggested water supply is based on renewable energy, the study found that it can be used at Federal Polytechnic Mubi to increase their supply for human use. As a result, the FPM management has reduced greenhouse gas emissions.

Abstract

This study examines the total concentration of particulate matter (PM) in Banjaran, an industrial sub-district located in the south of Bandung. Sampling was conducted using the gravimetric method with a mini particle counter measuring instrument, known as CEM DT-96. Sampling was carried out at a house and a school in 24-hours and five days of working hours. The results show that concentration of PM either during indoor or outdoor condition can be affected by activity, air temperature, air relative humidity, air ventilation area, and particulate deposition rate. In addition, air quality for industrial area was categorized as unhealthy. It is due to PM concentrations exceeding air pollution quality standards as highlighted by Environmental Protection Agency.

Abstract

Solar radiation enters the building through the glass by both radiation and conduction. The heat passing through the glass is one of the largest cooling loads. Therefore, modifying the glass type, will potentially reduce the cooling load significantly. This numerical study uses Cooling Load Temperature Difference (CLTD) method to calculate the change in cooling load in a five-story hospital. The Glass material was changed from clear glass to coated glass. Based on the calculation of cooling load per hour, from 07.00 to 19.00, it is obtained that the peak load occurs at 17.00, both when using clear glass clear and coated glass. The replacement of clear glass with coated glass results in a 70.0% decrease in radiation cooling load, from 104.59 kW to 31.38 kW. In addition, replacing this type of glass will reduce the total cooling load by 17.0%, from 418.80 kW to 347.57 kW. The decrease in total cooling load will lead to a decrease in the operational cost of the air conditioning system. If it is assumed that the AC system operates at 75% peak load for 16 hours per day, then replacing the glass will reduce electricity costs by approximately Rp. 43.6 million/month.
