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.

Abstract

Smart homes have been developed for the convenience and efficiency of energy use. Excessive lighting is one of the causes of wasted energy consumption. Smart light control is a solution. However, the control device used needs to be placed in the several points needed to turn on the lights, run the controller and the communication media so that the controller can adjust the lighting. This is very difficult during installation because an electric line is required to each light point. There are many AC / DC adapters for each light controller and there will be additional cables if a cable is used for the communication line. This study examines the use of Power over Ethernet (PoE) which is used for smart lamp installations where the ethernet data communication cable is not only used for communication but also used to transmit DC power to regulate lamp lighting. Whereas for room lighting settings, a reading of how much light intensity the room is used is so that it can be determined the number of lights that need to be turned on. The combination of smart home intelligence and easy system installation with PoE is the focus of this research.

Abstract

Although R134a has a very high global warming (GWP) effect, it is still used as a refrigerant in chest freezers. As an alternative to R134a is R290 which has a very low GWP value, which is only 3. Therefore, it is expected that there will be no more chest freezers using R134a and replaced with R290, soon. Thermodynamic studies need to be conducted to see the advantages and disadvantages of the two refrigerants based on experimental data. In this study, a chest freezer which was originally manufactured for R134a with a charging mass of 150 g was used as a test object. Experimental data of the chest freezer using R290 was taken after testing with R134a was completed. Experimentally, the cabin temperatures of the chest freezer using R134a and R290 are -20.5oC and -35.7oC, respectively, and the input power are 264 W and 176 W, respectively. Total irreversibility on the four main components of the chest freezer using R134a is greater than using R290, namely 184.4 W and 107.0 W, respectively. This means that the use of R290 as a working fluid in the chest freezer is more efficient. There are at least three advantages of replacing R134a with R290, namely reducing greenhouse gas emissions because R290's GWP is much smaller than R134a, lower cabin temperature, and decreasing the input power of the chest freezer.

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.

Abstract

This study examined the thermohydraulic performance of reverse flow solar air heaters (RFSAH) incorporating conical surface roughness geometries. A 3D computational fluid dynamics (CFD) model, developed using SolidWorks 2022, was employed to simulate heat transfer enhancement. The simulation utilized the average August solar radiation data for Bauchi, Nigeria (567 W/m²). Two conical roughness configurations were investigated, dimples and protrusions. The effects of the Reynolds number, pitch ratio, and height ratio on the heat transfer and fluid flow were analysed. The results revealed that conical protrusions exhibited a higher peak thermohydraulic performance factor (TPF) of 3.899. The optimal conditions for conical protrusions were determined to be Re = 5988.84, P/e = 5.7, and e/D = 0.2127, achieving a TPF of 5.0672, a 1.3-fold increase compared with unoptimized protrusions. These findings showed the potential of using surface geometries to enhance the efficiency of solar thermal systems while maintaining a favourable balance between the performance and pressure drop.

Abstract

Initially, Kota Baru Parahyangan was expected to have healthy air quality, because it is located far from the center of Bandung and the surrounding environment is still in the form of rice fields and small forests. However, because the entrance to Kota Baru Parahyangan is a confluence of vehicles from the west, east and the Padalarang toll gate, it causes severe vehicle congestion. The consequence of this density is an increase in PM10 and PM2.5 concentrations in the area. Therefore, the purpose of this study is to determine the air quality in the entrance gate area of Kota Baru Parahyangan. Particulate matter measurements of PM10 and PM2.5 were conducted for one week (7 days), from Monday to Sunday. There were three testing points carried out at the entrance gate area, namely at two points at the density location and one point towards the residential and business center. When evaluated using PP No. 22 of 2021, the measurement results show that the PM10 concentration for 7 days of measurement is still below the quality standard, but for PM2.5 there are 3 days where the concentration is above the quality standard. Meanwhile, when evaluated based on Permen LHK No. 14 of 2020, the average air pollutant standard index (ISPU) status for PM10 is “Medium” for points 1 and 2, and “Good” for point 3, but for PM2.5 the average status is “Medium” for all points. These results prove that the density of vehicles will have an impact on reducing air quality at points 1 and 2, while point 3, where the density of vehicles is relatively small compared to points 1 and 2, still has “Good” air quality for PM10. The relatively high concentrations of PM10 and PM2.5 at points 1 and 2 need to be addressed by the developers of Kota Baru Parahyangan and the West Bandung Regency government.

Abstract

This study aims to identify and analyze non-carcinogenic health risks posed by Particulate Matter (PM10 and PM2.5) exposure in Bandung Regency. The region is experiencing increased emissions of air pollutants due to rapid economic and population growth, especially in industrial and traffic-intensive areas. The study was conducted using the Environmental Health Risk Analysis (EHRA) technique to estimate the public health risks due to PM10 and PM2.5 exposure. Data were obtained through interviews, questionnaires, and direct measurements for PM10 and PM2.5 concentrations. The results showed that the average concentrations of PM10 and PM2.5 in the industrial area of Soreang-Kopo highway were higher (61 μg/m³ for PM10 and 46 μg/m³ for PM2.5) compared to the non-industrial area of Soreang-Ciwidey highway (30 μg/m³ for PM10 and 20 μg/m³ for PM2.5), but still below the quality standards set by regulation, PP RI No. 22 of 2021 which are 55 μg/m³ for PM2.5 and 75 μg/m³ for PM10. The highest level of health risk or RQ for PM10 and PM2.5 is 0.50 so it is declared safe (RQ<1), but even so there are 4 respondents who show RQ values>1, so further risk management is needed such as reducing pollutant concentrations, exposure time, and exposure frequency.
