Analysis of Dust Fall Levels in the City of Banda Aceh in 2008: A Comprehensive Study

Introduction

The city of Banda Aceh, located in the northernmost province of Indonesia, faced a devastating environmental challenge in 2008 due to the impact of the tsunami. The disaster not only caused widespread destruction but also had a significant impact on the environment, including the level of dust falling in the city. This study aims to examine the level of dust falling in the city of Banda Aceh, particularly in areas affected by the tsunami and those that are not. The main focus of this study is to evaluate how tsunamis affect dust levels and compare the results between the two regions.

Research Purpose and Hypothesis

The primary purpose of this study is to measure the level of falling dust in the area affected by the tsunami and those that are not affected by the tsunami. The proposed hypothesis is that there is a significant difference in falling dust levels between these two regions. In addition, this study also tested differences in lead content (Pb) and other parameters such as electricity conductivity (DHL), Total Dissolved Solids (TDS), and Total Suspended Solids (TSS) in both regions.

The research question that guided this study is: "What is the level of dust falling in the city of Banda Aceh, particularly in areas affected by the tsunami and those that are not?" The study also aims to answer the following questions:

  • Is there a significant difference in falling dust levels between areas affected by the tsunami and those that are not?
  • Are there differences in lead content (Pb) and other parameters such as electricity conductivity (DHL), Total Dissolved Solids (TDS), and Total Suspended Solids (TSS) in both regions?

Research Methods

The method used in this study is experimentation. The population studied was all dust levels falling in the city of Banda Aceh. The analyzed variables consist of independent variables, namely dust content, Pb levels, pH, DHL, TDS, and TSS, as well as the dependent variable which is an area affected by the tsunami. Data analysis was carried out using the ANOVA test and continued with the Duncan test at a significance level of 5%. In addition, testing the effect of variables is carried out by the F and T tests at 95% confidence level (α = 0.05).

Sampling and Data Collection

The sampling method used in this study is random sampling. The sample was collected from 10 locations in the city of Banda Aceh, 5 of which were located in areas affected by the tsunami and 5 of which were located in areas that were not affected by the tsunami. The sample was analyzed in the USU FMIPA Analytic Chemical Laboratory for PH, DHL, TDS, and TSS parameters. While the Pb content was analyzed at the USU Faculty of Agriculture Laboratory Medan.

Results and Discussion

The results of this study showed that the dust content fell in the third week of 0.5873 g/m²/day, which exceeded the threshold set for the residential area, which was 0.333 g/m²/day. However, Pb levels do not exceed the specified threshold, which is 0.06 mg/m². The results also showed that there are significant differences in falling dust levels between areas affected by the tsunami and those that are not.

The results of this study indicate that there is a significant influence on the level of dust falling on the area affected by the tsunami compared to the area that is not. Therefore, it is recommended that the government limits operational vehicles that are not feasible to test the highway to reduce Pb levels in the atmosphere. In addition, greening efforts need to be done by planting effective trees in absorbing dust and lead, so that air quality in the city of Banda Aceh can increase.

Implications and Recommendations

The results of this study have several implications for the city of Banda Aceh. Firstly, the study highlights the importance of monitoring falling dust levels and post-tsunami lead contamination. Secondly, the study suggests that the government should take measures to reduce Pb levels in the atmosphere, such as limiting operational vehicles that are not feasible to test the highway. Finally, the study recommends that greening efforts should be done by planting effective trees in absorbing dust and lead, so that air quality in the city of Banda Aceh can increase.

Conclusion

This study confirms the importance of monitoring falling dust levels and post-tsunami lead contamination. With the application of existing recommendations, it is hoped that a cleaner and healthier environment can be created for the people of Banda Aceh City, as well as helping to reduce the negative impact of air pollution.

Limitations of the Study

This study has several limitations. Firstly, the study only focused on the city of Banda Aceh, and the results may not be generalizable to other cities. Secondly, the study only measured dust levels and Pb content, and other parameters such as electricity conductivity (DHL), Total Dissolved Solids (TDS), and Total Suspended Solids (TSS) were not measured. Finally, the study only analyzed data from 10 locations in the city of Banda Aceh, and the results may not be representative of the entire city.

Future Research Directions

This study suggests several future research directions. Firstly, future studies should focus on other cities that have been affected by tsunamis, to see if the results of this study are generalizable to other cities. Secondly, future studies should measure other parameters such as electricity conductivity (DHL), Total Dissolved Solids (TDS), and Total Suspended Solids (TSS) in addition to dust levels and Pb content. Finally, future studies should analyze data from a larger number of locations in the city of Banda Aceh, to see if the results of this study are representative of the entire city.
