Abstract

Urban activities and runoff deteriorated the river water. Aim: This study aims to determine the primary contamination and mapping river's water quality variation in Greater Jakarta. Methodology and Results: Multivariate analysis was employed by Factor Analysis and Cluster Analysis (FA and CA) using the 12 parameters of the water quality dataset from 76 sampling stations in 19 rivers in the Greater Jakarta Region, Indonesia, between 2014 and 2015. The FA result showed that almost 66.6% of the total variance in water quality data was associated with four significant variators of which 36.12% identified the main parameters BOD, COD, TP, ammonia, nitrate, and detergent. The cluster analysis grouped the sampling locations into 3 (three) clusters to indicate the spatial classifications of river water. Cluster 1 indicates pollutants from the residential area, Cluster 2 from residential and commercial areas, while Cluster 3 is majorly pollutants from industrial areas. Conclusion, significance, and impact study: The results showed the conductivity and TDS concentrations in cluster 3 are higher than the others since most of the sampling points are located near an industrial area or downstream close to the estuary. The mapping gave a better understanding of the river water quality characteristic spatially and could assist local governments in prioritizing river pollution management.

Abstract

One of the biggest environmental issues facing the planet today is plastic garbage, which was created by people and has an effect on them as well. Although though governments have implemented policies, rules, and other initiatives to increase public awareness of and engagement in decreasing plastic trash, the statistics has not changed, and this amount keeps rising every year. Several nations appear to be having trouble solving this problem. In addition, according to the World Bank, the country produces more plastics the wealthy its citizens are. By evaluating behavior and educating people, culture and education can be the answer to this problem. As people get more educated, their awareness of and care for the environment increases. The relationship between each of these factors—culture, education, national income, and government role and environmental problems might potentially help minimize plastic waste. Consequently, the goal of this study is to pinpoint the variables that may have an impact on the volume of plastic garbage and examine how these variables may affect the quantity of plastic waste in various nations. Hofstede's national culture dimension (Power Distance, Collectivism and Individualism, Masculinity and Femininity, Uncertainty Avoidance, Long-term Orientation and Short-term Orientation, Indulgence and Restraint), wealth per capita, education, and the government's plan and policy on sustainable consumption are the variables that will be examined. In this study, worldwide data for the year 2018 is gathered from 66 different nations utilizing secondary sources, and the data is then analyzed using the Multiple Linear Regression approach. According to the findings, there is a strong correlation between individualism and collectivism and the volume of plastic garbage. The results of this study should help each nation's government reduce the quantity of plastic garbage that is generated.

Abstract

Indonesia has a large amount of liquid waste originating from the tofu industry. Currently, the treatment of tofu industrial wastewater is carried out using both anaerobic and aerobic methods, but both methods still have several weaknesses. In this study, the tofu industrial wastewater was utilized as a culture medium for Spirulina sp. to provide economic value from wastewater that can be used as bioethanol, pharmaceuticals, and food products rich in omega 3, chlorophyll, carotenoids. Aim: The growth of Spirulina sp. is closely related to the availability of macro and micronutrients as nutrients and the influence of environmental conditions, so this study was aimed to see the best variation of the addition of urea and NaHCO3 as additional nutrients to maximize growth and cell density of Spirulina sp. with tofu industrial wastewater media. Methodology and Results: This study was done by culvitating Spirulina sp in the growth media, measuring the Optical Density (OD), and analyzing quantitatively and using ANOVA on IBM SPSS Statistics version 20. The study indicated that adding urea and NaHCO3 to Spirulina sp. had no effect on cell density and growth rate. Treatment with addition of urea 0.36 g/500 ml without additional of NaHCO3 had the highest growth rate, 0.00852/day, and the highest cell density value on Spirulina sp. growth. Conclusion, significance, and impact study: The tofu liquid waste can be used as a new alternative used as fertilizer because in the liquid tofu waste, it provides the nutrients needed by Spirulina sp.

Abstract

Indonesia is a country that has considerable coal reserves with coal resources of 149.01 billion tons. One of the problems of coal mining is turbidity. The turbidity is caused by the excavation of the open pit mine so that rainwater contact with the main wall. So that mud is formed, which can increase turbidity levels. The concentration of Total Suspended Solids (TSS) due to this phenomenon reaches 5,400 mg/L. Aim: This study aims to set aside TSS by electrocoagulation processing method using a batch system with eight pairs of iron electrodes arranged monopolarly. Methodology and Results: Comparisons using statistically independent t-tests showed that there was no significant difference between the iron and aluminium electrodes in the pH parameter. Conclusion, significance, and impact study:There were significant differences between iron and aluminum electrodes in the parameters of TDS and TSS. In the measured TDS and TSS parameters, the electrocoagulation process using iron electrodes has a higher value than aluminum electrodes. In the TSS removal, there is no significant difference between the two electrodes (iron and aluminium).

Abstract

Suburban areas often experience development pressures, with implications for changing green space into built areas, rural cultures into urban ones, and poverty into prosperity. The development of Buring Kampong (suburban settlement) in Malang City into a tourism kampong, in addition to improving the local economy, must also be able to support environmental quality and community independence. This research used the Asset Based Community Development (ABCD) approach in identifying tangible and intangible assets. The data were collected through field observation, focused group discussion, interviews, and secondary data. Tangible aspects include land use, natural and artificial resources, infrastructure, accessibility, machinery and equipment, and local architecture. Meanwhile, intangible assets include intellectual property, potential branding development, goodwill, software/web, formal and informal organization, social and cultural values, and potential customers. The data obtained were presented descriptively and discussed together, as a triangulation process. The results showed the diversity and breadth of tangible and intangible assets of Baran village, and both of these assets can be directly found in the field and during FGDs and interviews. This research is also an effort to strengthen community engagement and public awareness about their assets, and this activity needs to be continuously improved, to have a better level of community engagement, confidence, social participation, branding, and networking.

Abstract

Groundwater is a natural resource used by humans to fulfil their living needs which should meet the Republik Indonesia Minister of Health Regulation No. 2/2023. Aim: This research aims to contribute to solve these challenges and meet the clean water quality standard. Methodology and Results: The groundwater sample was taken from the deep well of Al-Hikmah Mosque, Universitas Negeri Malang (UM). It was indicated to contain Fe and Mn, as evidenced by its yellowish colour when left undisturbed for some time. A laboratory-scale experiment was conducted for the deep well treatment and analysis. The treatment system consists of aeration, sedimentation, and filtration. The filtration unit comprises several natural media such as gravel, silica sand, zeolite, and activated charcoal. This experiment used detention times of 120 and 240 minutes as dependent variables. Conclusion, significance, and impact study: The results showed that detention times of 120 and 240 min have efficiency on turbidity reduction of 92.86% and 98.69%, Total Dissolved Solids (TDS) of 10.42% and 14.47%, Fe of 23.01%, Mn of 62.39% and 94.70%, and for CaCO3 of 2.98% and 11.17%, respectively. The research findings demonstrated that a detention time of 240 min generated water quality that met the Minister of Health No. 2/2023 standards. Detention times of 120 minutes and 240 minutes led to significant differences in water quality concerning temperature and CaCO3. The filtration system with a detention time of 240 minutes can be considered as an alternative groundwater treatment solution for the deep well of Al-Hikmah Mosque, Universitas Negeri Malang.
