Enzyme-based sensors frequently produce unsatisfactory results such as poor reproducibility and insufficient long-term stability due to the natural instability of enzymes, stringent experimental conditions, and complicated immobilization procedures. Thus, an electrochemical non enzymatic sensor was fabricated by deposition of the multi-walled carbon nanotube (MWCNT) with zinc oxide nanoparticles (ZnO NP) and also molecular imprinted polymer (MIP) on a screen-printed carbon electrode (SPCE). Then, the modified electrode (SPCE/MWCNT/ZnO/MIP) was formed on the surface area of the SPCE. This study wanted to demonstrate the glucose detection between molecular imprinted polymer (MIP) which contained glucose as template, o-phenylenediamine (oPD) and potassium persulfate as initiators in 0.1 M PBS at pH 7 and non-imprinted polymer (NIP) without addition of the template. The characterization and evaluation of various factor such as sensitivity, selectivity and limit of detection (LOD) were investigated through cyclic voltammetry (CV) and scanning electron microscopy (SEM) was used to look up onto the surface area of the modified electrode. The SPCE/MWCNT/ZnO/MIP electrode sensor showed a linear glucose concentration range from 0, 0.5, 1, 2 to 5 mM (R2 = 0.9709). The sensitivity of the sensor was 0.3386 μA mM-1 cm-2 with low detection limit of 1.81 mM. The sensor showed good stability and reproducibility along with excellent anti-interference properties to ascorbic acid, lactic acid, tartaric acid, and acetic acid. Finally, the applicability of the as-prepared SPCE/MWCNT/ZnO/MIP electrode sensor was successfully studied for detection of glucose. The results obtained for our sensor confirm that it is a promising non-enzymatic glucose sensor to be used for practical purpose.

Biodegradation of an antimicrobial compound triclosan under sulfate reducing condition Raj Boopathy; Jacob Cortez

Triclosan is an antibacterial and antifungal agent that is present in many detergents and surgical cleaning treatment products. This antimicrobial compound is discharged from households and collected at the local sewage treatment plant. Because triclosan inhibits phospholipid biosynthesis, it affects the microbial population that perform waste degradation. Sewage treatment plants are the major reservoir of triclosan as the wastewater from various households are discharged and treated in the local sewage treatment plant. This study was conducted to determine whether triclosan degradation occurs in the anaerobic digester of the Thibodaux Sewage Treatment Plant. Bacterial enrichment cultures were developed under various electron acceptor conditions including nitrate-reducing, sulfate-reducing, and mixed electron acceptor condition. The results showed the bacterial consortia developed under various conditions were not inhibited by 100 ppm of triclosan. More than 96% of triclosan was removed in both co-metabolic and triclosan as the sole carbon source conditions under sulfate-reducing condition. The molecular analysis of the consortium showed wide biodiversity of bacteria in the consortium.

There have been many literature reviews on the presence of MPs in water, but study on the presence of MPs in the air and literature reviews on it have not been done much. study on MPs pollution needs to be collected and summarized into one literature review so that this information is easy to find and not scattered. The results found 16 research articles discussed the findings of MPs in ambient air. The 16 research articles found MPs pollution in each location with different levels, the form of MPs in the air that they found the most was fiber because the fiber was lighter in size compared to other MPs shape like fragment, film, or granule. fiber small surface area and thin shape similar like a thread make it easy to be carried by the wind in the air. it turns out that there are 3 main pathways of how MPs enter the human body. the first is by respiration because MPs have been proven to pollute the air human breath, and this supported by a recent study that found MPs in human lungs, a total of 39 MPs were identified within 11 of the 13 human lung tissue samples. the second way is through consumption, because humans consume a lot of seafood that lives in the sea that is contaminated with MPs. MPs are also found in bottled drinking water, fruit, milk, honey, almost all food and beverages consumed polluted by MPs.

Assessment and optimization of a natural coagulant (Musa paradisiaca) peels for domestic wastewater treatment Nur syamimi zaidi; Won Chin Ting; Zhang Zhan Loh; Muhammad Burhanuddin Bahrodin; Nik Azimatolakma Awang; Abudukeremu Kadier

Sustainable wastewater treatment necessitates the application of natural and green material in the approach. Thus, selecting a natural coagulant in wastewater treatment is a crucial step to prevent secondary environmental pollution due to residual inorganic coagulant in treated effluent. Present study investigated the application of Musa paradisiaca (banana) peels in domestic wastewater treatment. From the experimental results, the banana peels were found to have a higher yield with lower moisture content compared to the other fruit wastes. The surface charge of the banana peels was +6.53 meq/g MLSS while the recorded protein composition was 0.248 mg/L. The scanning electron microscopy (SEM) showed that banana peels has rough and pore surfaces compared to the others fruit wastes. At optimum conditions of 50 mg/L dosages, pH 4, and 100 rpm of agitational speed, the maximum turbidity removal of up to 89.9% with initial turbidity of 76 NTU was obtained. The banana peel was also evidenced in efficiently removing COD and NH4-N from domestic wastewater up to 80.0% and 62.5%, respectively. Overall, the findings suggested that Musa paradisiaca (banana) peels is efficient and suitable to be applied as the natural coagulant in treating domestic wastewater.

Trends in integrated waste management research: A content analysis Edza Aria Wikurendra; Imre Nagy

Analyze the trends that characterize scientific production through textual statistics and text mining methods, highlighting the most debated topics useful for developing new research perspectives in this field. Textual statistics and text mining methods were chosen to analyse the real scope of integrated waste management, focus the investigation on the central elements of their discussion, and the trends that characterized scientific production in that field. Two argumentative dimensions that characterize the corpus, the one with the greatest response, in terms of quotation, is aspects with 48 extracted quotations. This result indicates how scientific research focuses more on the relationship between integrated waste management and waste treatment, recycling, disposal, and environmental. The analysis made it possible to define the most debated issues in integrated waste management clearly. From an elements point of view, integrating waste management depends on the treatment, recycling, and disposal.

A review of current status, challenges, and solution to improve waste management Goh Zhu Hang; Tony Hadibarata

Government plays the most important role in improving the waste management system. Incineration system can be introduced into the waste management system to incinerate specific type of waste. This will increase the availability space for the landfilling process. However, the incineration process must be carried out with full pollution control system to prevent and minimize the pollution that might cause during the incineration process. Other than that, the government should encourage the public to separate out the waste into different categories before the collection of the waste by the waste management company. This can be implemented by providing guideline for the separation of waste methods as well as encouraging the public to be responsible for own produced waste. The dumpsites must also be improved and it is suggested that all dumpsites used are engineered sanitary landfill. An engineered sanitary landfill will reduce the impact of the pollution towards the environment to the minimum. Better tools also must be included in the sanitary landfill system to monitor the condition of the landfill site. This will prevent the happen of any unexpected conditions and can be resolve before the happening of the unexpected condition. Last but not least, the government should implement new charging fee system for the waste management. The charging fee should be based on the rate of waste generated but not flat pricing. This will help in reducing the waste generated as all individuals must pay for their own generated waste. The earth belongs to everyone which indicates everyone have the responsible to keep the earth clean and to reduce the waste produce.
