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.
