Abstract

The use of chemicals in practical activities or research in the laboratory will certainly produce wastewater. Wastewater generated from the laboratory is classified as hazardous and/or toxic waste. Based on the substances contained in laboratory wastewater in terms of accumulated amount and a long period of time, wastewater will pollute the environment and will have an impact on living things around it if it is directly discharged into water bodies. The composition of laboratory waste is reactive and dangerous because it contains heavy metals Pb, Fe, and Cu as well as high Chemical Oxygen Demand (COD) and Total Suspended Solid (TSS) so it is difficult to decompose in nature. This study aimed to prepare the laboratory wastewater using the coagulation process as pretreatment. Therefore, this research prioritized the reduction of heavy metal levels of Pb, Fe, and Cu and reduced the content of COD and TSS with Alum as a coagulant. The highest degradation percentage of COD and TSS content occurred at the Coagulation Dose of 80 ppm, namely 99.79% and 99.80% respectively. Meanwhile, the highest degradation percentage of heavy metal levels of Pb, Fe, and Cu as well as the optimum COD and TSS content occurred at a stirring time of 60 minutes respectively, which were 49.48%, 58.96%, 94.09%, 99.97%, and 99.40%. It was concluded that the pretreatment of laboratory wastewater using the coagulation process could reduce the levels of Pb, Fe, and Cu metals, and the content of COD and TSS.

Abstract

Mthatha town of Eastern Cape Province, South Africa has been challenged to address the pollutant issues that are coming from rampant densification and effluent concentration discharge from the Mthatha Correctional Services Centre and the Efata School for the Blind and Deaf which have caused ineffable impaired damage to the Mthatha River Catchment (MRC). This paper is aimed at identifying drivers of poor water quality in the catchment and classified the River’s water quality into different cluster groups for proper pollutant source control measures. Water quality parameters data comprising of pH; conductivity; Phosphorus; Ammonia (NH4-N); Feacals; and E-coli covering 95 percent and 105 percent of the upstream and downstream sections of the River were available at ten monitored sites of the river catchment. These datasets covering eight years 2012-2020 were analysed in this study. Factor analysis as a choice of principal component analysis (PCA) and Agglomerative Hierarchical Clustering (AHC) was used to deduce inferences for the pollutants’ subsequent classification. The results classified the catchment into three different clusters of lower pollutant (LP), medium pollutant (MP), and high pollutant (HP) areas, with PC1 accounting for 84.54% of the total variance from the three components classification. Adaptive catchment managers would find usefulness in the employed statistical tools in ensuring real-time measures for river non-point pollutants sources control that could offer additional benefits in maintaining a safe life above and below water in the preservation of their public values benefit. The study recommends the issuance of compliance notices and non-point pollutant source control measures to improve the water quality (WQ) parameters.

Abstract

High organic pollutant in tofu wastewater (TWW) raises a negative impact on environmental sustainability and health. Therefore, the TWW must be treated before it is discharged into the environment. Microbial electrolysis cell (MEC) is one of the green technologies that can be used to treat wastewater and generate hydrogen as well. This work tries to investigate the performance of MEC based on the decrement of organic pollutants in TWW. Some important parameters of organic pollutants in TWW such as chemical oxygen demand (COD), biological oxygen demand (BOD), total suspended solids (TSS), total dissolved solids (TDS), total solid (TS), and pH were evaluated before and after MEC operation. The results showed that the COD and BOD levels decreased around 56% and 35% while pH increased from 7.90 to 7.16. Additionally, the TSS, TDS, and TS decreased by around 35.0%, 45.5%, and 33.2%. In addition, the optimum hydrogen yield (YH2) and hydrogen production rate (QH2) were obtained at 114 ± 0.1 mL H2/g COD 360 ± 20 mL H2/L/d. Overall, the MEC system could be used to reduce the level of organic pollutants in TWW and generated H2 at the same time.

Abstract

A successful sustainable city prioritizes humans by integrating the transportation system with urban development. One of which is considering walkability. The walkability concept is important since walking reduces congestion, promotes low environmental impacts, and possesses social and economic values. Land use integration with walkable pedestrian facilities is a challenge for stakeholders in creating policies to actualize a sustainable city. This paper reviews the walkability condition and policies concerning pedestrian facilities in Brisbane, Australia and Bogor, Indonesia. Bogor was selected due to its strategic location as Jakarta’s satellite city. Method used was literature review with comparative analysis, analyzing similarities, differences, advantages, and disadvantages of urban policies in prioritizing humans to achieve walkable and sustainable city in Australia and Indonesia. The indicators determining Brisbane community’s behavior to walk are distance to destination (59%), travel time (14%), hot weather (19%), roads with various altitudes (4%), lack of paths (3%), and lack of green areas (1%). In Bogor, Indonesia, pedestrian facilities are lacked for people with special needs, elderlies, children, and pregnant women (16.5%), unsafe crossing facilities (19.8%), and unsafe rider behaviors (15.8%). Policies related to walkability can be used as a basis to influence the behavior of urban communities in walking, to achieve the shared goal: a sustainable city.

Abstract

Rubber industrial wastewater is obtained during washing, shredding, grinding, crumbbing, drying, and pressing bokar. The wastewater produced can be an environmental pollutant because it contains relatively large amounts of organic matter. One alternative to treating rubber wastewater is to use the electrocoagulation process, which is a combination of the coagulation and electrolysis processes. This electrocoagulation process has several advantages in the form of simple equipment, short time, produces odorless wastewater, does not require large areas of land, and can remove various contaminants in water. In this study, rubber wastewater was treated by electrocoagulation using a batch system with variations in the contact time used, namely 20, 40, 60, 80, and 100 minutes. This type of research is experimental research, and descriptive analysis is carried out. Rubber wastewater is physically gray-black before treatment and chemically contains large organic matter. The results of this study showed that the content of chemical oxygen demand (COD) and total suspended solids (TSS) before processing had values of 691 mg/L and 317 mg/L. Optimum conditions for the elimination of COD and TSS contents were achieved within 80 minutes with the percentage of elimination being 89% and 85%.

Abstract

Making sure that the health and environment are taken care of, solid B3 Waste produced by hospitals has to be treated according to existing regulations. As an A-class hospital in Bandar Lampung, AM General Hospital commit to conducting good practices for its solid B3 waste management. This study aims to analyze the current implementation of solid B3 waste management, the compliance of AM General Hospital’s B3 waste management Standard Operation Procedure (SOP) with current regulations, and recommend improvement strategies for solid B3 waste management in AM General Hospital. For eight consecutive days in August 2022, solid B3 waste samples were collected and analyzed. The average solid B3 waste produced by AM General Hospital was 285 kg/day for infectious waste and 6.3 kg/day for sharp waste. Inpatient installation contributed the majority of solid B3 waste there. Due to the observation sheet that was created according to the regulations, 65% of AM General Hospital’s SOP involving sorting; storage; collection; transportation; and disposal has already complied with the regulations. Several shortcomings were found such as the absence of an official solid B3 waste handling report; the absence of proper labeling in the B3 waste containers; and the use of black plastic bags. Analytical Hierarchy Process (AHP) data analysis technique was deployed, resulting in a technology application and waste minimization as improvement recommendations.

Abstract

Medical mask waste is generated more and more and causes many negative impacts on the environment and human health. This study was conducted to survey the current status of using and managing medical mask waste by students at Can Tho University, Vietnam. The study conducted by direct interviews with 120 students and field observations of the research area. As a result, students of Can Tho University use about 43,850 masks resulting in 153.475 kg of medical mask waste per day. Medical mask waste was not well classified by students. Understandings of students regarding toxicity and non-biodegradable characteristics of medical masks are relatively high. However, the level of awareness of students about medical mask waste has some limitations, through the way that medical masks are considered as household waste and are not really necessary to pay attention to the classification of medical masks. As can be seen that training on waste classification and associated waste containers are urgently needed for better solid waste management in the university. This research will contribute to enriching scientific data sources in the field of solid waste, especially medical mask waste.

Abstract

Deforestation, land degradation, and low survival of planted seedlings are serious problems in highland Ethiopia. To address these problems, different land management practices such as afforestation and conservation program have been implemented; however, the success to date limited due to environmental stress and insufficient post-planting care. Therefore, the objective of this study was to investigate farmer’s tree needs and their traditional knowledge of seasonal frost management practices in selected frost-affected highlands of Eastern, Ethiopia. A total of 111 households were randomly selected for interviews on farmer’s tree species preference, frost management practices, and the causes of seedling mortality in the study area. Furthermore, key informant interviews and focus group discussions were used to collect the data. Descriptive statistics were used to analyze the data. The results confirm that season frost (55.6%) followed by free grazing (22.2%), inappropriate species site match (11.1%), and inappropriate planting time (5.6%) were major causes of seedling mortality in the study area. Organic mulch, plant cover, smoking, watering, and manuring were seasonal frost management practices applied by farmer’s to enhance seedlings’ survival in the study areas. However, this indigenous knowledge should be encouraged by the government through improved research, and extension services, to enhance seedlings’ survival in the study areas as well as to introduce it in different frost-prone highlands of Ethiopia. Moreover, species such as Eucalyptus globulus’ Labill, Cupressus lusitanica Mill., Juniperus procera Hochst. ex Endl., Hagenia abyssinica a (Bruce) J.F.Gmel, and Podocarpus falcatus (Thunb.) Mirb. (syn. P. gracilior Pilg.), were suggested as frost-tolerant species in the study area. Therefore, it is recommended that planting these tree species through research and campaign is essential to reduce land degradation in the frost-affected highlands area of the country, particularly in the study area.

Abstract

Triclosan is an antiseptic ingredient that is commonly found in numerous personal care items that may end up in the environment. Their ecotoxicological profile, however, is still unknown. The current research aims to determine the toxicity of triclosan on E. coli, Vigna radiata and Crotalaria juncea seeds, and Allium cepa roots. The analyses include toxicity assays for microbes, phytotoxicity, and cytogenotoxicity. The results proposed if the triclosan tested (60-150 µM) became exceedingly harmful to the test bacterium, as seen by the decrease in E. coli CFU, indicated that triclosan had antibacterial properties and inhibited the test microbe, depending on the concentration of triclosan used. Triclosan at concentrations of 40 and 80 µM, respectively, decreased the sprouting length of Vigna radiata and Crotalaria juncea by 45-50% and 70-72%, respectively. Thus, the cytogenotoxicity assay using Allium cepa revealed that triclosan damages the meristematic cells. Triclosan at 40 µM concentration resulted in a 1.2% aberration index and a 10.4% mitotic index, and 80 µM caused a 1.4% aberration index and an 8.8% mitotic index. All of the findings point to triclosan being potentially hazardous to the biota.

Abstract

The water system or hydrological indicators determine the good and bad of a watershed’s carrying capacity. The hydrological indicators include discharge fluctuations, annual flow coefficient, sediment load, flood frequency, and water use index. The purpose of this study was to evaluate the carrying capacity of the Wanggu watershed based on hydrological indicators. The method used is the score and weight method for all hydrological indicator data in accordance with the watershed evaluation guidelines for hydrological indicators. The research data is sourced from primary data and secondary data. Primary data comes from direct observation, while secondary data comes from agencies related to this research. Data analysis using Microsoft Excel in monthly and annual data analysis by producing tables and figures. The results of this study indicate that fluctuations in discharge or the regime coefficient of the Wanggu River Basin are 96.45 which are classified as high, as well as erosion and surface runoff, namely sediment load conditions of 19.73 which are also included in the high category. While the value of the annual flow coefficient is 0.32, the average frequency of flooding every year occurs once in two years and the water use index is 0.69. The three parameters are categorized as being in the middle class. From the accumulated weights and scores of all water system indicator parameters, a value of 111.25 is included in the bad class category. So the Wanggu watershed has a poor carrying capacity value from the water management indicator.
