Abstract

Aims: This study aims to improve waste bank activities in Medan and make them more efficient Methodology and Results: The study involved the collection of secondary and primary data. The secondary data collected involved a general description of the study area, number, status, and location of the waste bank. Primary data included interviews and field research on selected waste banks. Importantly, survey and data collection were conducted from December 2017 to April 2018. A semi-structured interview survey approach was conducted to collect the data. Using the Material Flow Analysis (MFA) methodology, the findings of the study showed that of the total amount of the input material, 87.4 % is a recyclable waste and 12.6 % water. Also, the waste bank activities generate 87.2% recyclable items, 12.6% wastewater, and 0.2% residues. Conclusion, significance, and impact study: The findings are essential in understanding the use of resources to provide information for improving waste bank activities and waste management. Apart from the community, the government also plays a significant role in supporting the future of waste banks. This study found that waste bank activities are still conventional, with no technology adoption. In the future, the waste bank should be more efficient and manage large amounts of wastes, because the potential for recyclable products is still abundant.

Abstract

Aim: This study aims to determine the potency of horsetail plant to remove heavy metal concentration. Methodology and Results: Data was obtained from fifty-four (54) horsetails which were divided into three batches of 12, 18, and 24 plants respectively. Furthermore, the experimental method with the subsurface flow system treatment was used with two samplings for seven days. The results showed that the first, second and third batches gave a 6.83%, 10.28%, and 16.26% impact on reducing concentration of Fe respectively with an approximate average of 11%. Therefore, the detention time of the leachate constructed wetland reactors significantly reduced the Fe contaminant. Conclusion, significance, and impact of study: This research provides a solution to mitigate the environment by adopting the accumulator of Horsetail plants (Equisetem hyemale) in the constructed wetlands reactor experiment. From the three reactors approximately 0.03 mg/L of heavy metal iron was removed after a seven day run. Therefore, horsetail plant showed a positive impact in reducing environmental pollution, a trend adoptable in wastewater and leachate treatment technology in Indonesia.

Abstract

Aim: This article was meant to review the current status and limitations of treating municipal solid waste (MSW) by the developing countries with a case study from Peshawar-Pakistan. Methodology and Results: The city is divided into 4 towns and used a stratified sampling and survey to inspect MSW management from collection to final disposal. The results show food contributes to 14.3% of the total waste, followed by plastic waste 4%, paper, 2.7%, glass 1.2%, wood 1.1%, and metals/rubber 0.6%. Conclusion, significance, and impact study: About 60% of the wastes at collection points make the air difficult for breathing. There are several treatment options for the sustainable management of MSW, including composting, incineration, gasification, pyrolysis, biological treatment, and recycling. The developed countries had strictly imposed regulations to increase waste recycling and material recovery. In contrast, in the developing countries, the lack of proper legislation, planning, and awareness regarding waste reduction has worsened the MSW related problems. In this article, the essential steps needed in formulating the strategy for sustainable MSW management and assessment in terms of sustainability in the developing countries have been considered.

Abstract

Aim: This study aimed to compare the secured landfill method and thermally sludge treatment through gasification, in order to determine their environmental impacts. Methodology and Results: The gate-to-gate LCA method was the implementation approach used to determine the, limits and assumptions to the actual condition. The experimental, theoretical mass balance calculation and secondary data of previous researches were used to carry out this study, with open-source openLCA software. In addition, the LCA was made up of four phases which include goal and scope definition, inventory analysis, impact assessment, and data interpretation. The simulation showed that the implementation of the thermal gasification process reduced the emission released to the atmosphere by lowering the hazardous sludge volume which is directly transported to the secured landfill. Conclusion, significance and impact study: Several assumptions and adjustments were made to the simulation results using the openLCA software, in the determined scope of study. Therefore, in conclusion, the thermal (gasification) treatment of hazardous sludge is further studied in connection with its implementation at the treatment plant. This was indicated by the acquisition of global warming potential impact category of 673 kg CO2 eq for direct disposal to secured landfill, which reduced to 424 kg CO2 eq during the implementation of thermal treatment. Conversely, there is a reduction in magnitude of impact by 37%.

Abstract

Aim: This study aimed at comparing predictor variables associated with the environmental quality of first child. Since the beginning of 1987, Indonesian National Family Planning Board (BKKBN) has been discouraging early first marriage (marrying before 20 for females and before 25 for males). In 2016, BKKBN recommended ideal ages of marriage for females and males as old as 21 and 25 respectively. Methodology and Results: This study was a retrospective analysis involving 5 groups of data reported within the period of 1994-1997 (n=34,225), 1997-2000 (n=34,227), 2001-2004 (n=33,088), 2005-2009 (n=40,701), and 2009-2012 (n=45,607). Data were collected from the Indonesian Demographic and Health Survey datasets (SDKI [Survei Demografi dan Kesehatan Indonesia]). Data were analyzed using chi-square tests. Results indicated several variables that significantly contributed to the first child’s environment quality: (1) residential area (p value<0.05); (2) mother’s educational background (p value<0.05); (3) mother’s exposure to information media (p value<0.05); (4) mother’s employment status (significance were only found in two groups of data:  1994-1997 and 1997-2000 with each p value<0.05); (5) father’s educational background (p value<0.05).    Conclusion, significance and impact of study: In conclusion, there was an inconsistency with regard to strong and weak potential factors of first child’s environment quality within an eighteen-year period. It is recommended to reassess the predictors. It is also important to develop strategies to improve marriage quality and family formation.
