However, overexploitation, anthropogenic activities like tree cutting for development and agriculture, as well as natural disasters, have caused severe damage and changes to the Sundarbans. This research aims to detect changes in the mangrove forest areas and create an above-ground biomass map of the Sundarbans Forest. Previous studies relied on time-consuming and inaccurate traditional methods, while this study seeks to make a significant contribution to mangrove mapping and forest resource management. Landsat 5 and 8 images from 2007 to 2017 were used to generate the mangrove index (including CMRI and MI) for different years. ALOS-PALSAR 2 and JERS images from 1996, 2007, and 2017, with HV+HH polarization, were processed to calculate the backscatter ratio, enabling identification and estimation of vegetation loss and gain over the years. To estimate the above-ground biomass (AGB), tree height was derived from SRTM DEM, and an allometric equation was used to calculate AGB. The results indicate a continuous shrinkage of the mangrove forest. The 2017 maps of the two different indexes reveal significant mangrove vegetation loss compared to 1996 and 2007. Additionally, the study estimates the total above-ground biomass of the Sundarbans mangrove forest to be 329 million tons. The findings can assist relevant authorities in taking necessary action, formulating policies, and implementing plans for sustainable management of the Sundarbans mangrove forest resources.","PeriodicalId":32450,"journal":{"name":"IJEMS Indonesian Journal of Environmental Management and Sustainability","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135641797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to assess the working environment factors that influence construction workers' performance in Nigeria. A quantitative research approach was adopted, utilizing a five-point Likert-based questionnaire for data collection. A total of 200 questionnaires were distributed, resulting in 187 valid responses, which is considered adequate for analysis. The results indicate that 11 out of the 16 hypothesized barriers were statistically significant, surpassing the set threshold of 3.5. The most significant factors influencing construction workers' performance in the working environment were found to be disputes among workers, poor weather conditions, equipment failure, changes in orders during unpredictable execution, and major rework due to unforeseen conditions. Through factor analysis, the barriers were categorized into three components: \"Physical and Social-related barriers,\" \"Operational-related barriers,\" and \"Welfare-related barriers.\" This study highlights the paramount importance of working conditions in determining employee performance and recommends the development and implementation of strategies to mitigate working condition challenges in the construction industry.

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.

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.","PeriodicalId":32450,"journal":{"name":"IJEMS Indonesian Journal of Environmental Management and Sustainability","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89233496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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%).

Despite the nutritional benefits obtained from fruit consumption, the presence of heavy metals accompanying it from the environment draws scientific concerns affecting the human health. The multi-stage and random sampling techniques were used in dividing the area into three with three markets. Ninety-five fruit sellers participated in the study. The instruments used for data collection were field observation, questionnaire and laboratory analysis. Twelve fruit samples of banana, watermelon, apple and pineapple, four from three markets were collected. Also, three samples of unripe banana fruits were collected, to compare the percentage increase in the concentration of arsenic that might be arising from the use of calcium carbide. ANOVA was used for data analysis. Results revealed that the concentrations of Zn, Ni, Cu, Pb and Cr in all fruits were within WHO/FAO’s acceptable limits of heavy metals in fruits. Whilst As and Fe were above the limit. Results also indicated an increase in the concentration of As in ripe banana compared with unripe one. Findings showed that 80% of the respondents were not aware of the health implication of consuming of CaC2 ripen fruits. There was no significant relationship between the concentration of Zn, Ni, Cu, Pb and Cr in fruits sold in markets and human health risks as the Fcal value of the metals was less than Fcrit at (P<0.05) level of significance. However, there was a significant relationship between the concentrations of As and Fe and human health risk as Fcal was greater than Fcrit at (P˃0.05) level of significance, which shows the serious human health risk associated with As and Fe toxicity.","PeriodicalId":32450,"journal":{"name":"IJEMS Indonesian Journal of Environmental Management and Sustainability","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83072966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tannery wastewater is usually characterized by high BOD, COD, TDS, and TSS and a high percentage of dissolved organic and inorganic matter. The central effluent treatment plant (CETP) of industry plays a vital role in sustainable industrial waste management and saves different lives from harmful effects. The study aimed to analyze various physicochemical parameters of the composite tannery influent and effluent as well as the removal efficiency of the CETP of the Savar Tannery Industrial Zone in Bangladesh. It was carried out at Savar Upazila, situated in the northwest part of Dhaka, Bangladesh. The samples were collected three times (pre-monsoon, monsoon, and post-monsoon) in a year, from monsoon 2021 to pre-monsoon 2022. The major water quality parameters for the influents and effluents included pH, BOD, COD, TDS, TSS, NO3-, SO42-, HCO3-, PO43-, Cl-, Na, Ca, Cr, Fe, Cu, Zn, and Pb. Most of the parameters, especially BOD, COD, TDS, and TSS after treatment, exceeded the standard permissible limits of effluent discharge prescribed by the ISW-BDS-ECR (1997), DoE-BD, and NEQS (2000), and these values were two times higher than the permissible limit. The DO value was four times lower than the permissible limit, indicating heavily polluted water. The concentration of the cations in the tannery effluents was in the following order: Na>Ca>Cr>Fe>Cu>Zn>Pb. The analysis results illustrated that the overall removal efficiency of the CETP was about 47%. The study observed that the performance of the CETP was not satisfactory, and hence it needs further improvement in the treating capacity for sustainable industrial wastewater management.","PeriodicalId":32450,"journal":{"name":"IJEMS Indonesian Journal of Environmental Management and Sustainability","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82534870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
