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

International Construction Costs published in Comparison 2020 continued to increase as an impact of the Covid-19 pandemic, The modular system is considered able to answer the problems of increasing costs. Although modular construction has been widely applied to low-rise buildings, application in high-rise buildings remains limited, less than 1% worldwide. The need for residential high-rise building applying modular construction in Indonesia becomes important. The interdependence between parties in modular projects is greater than in conventional methods. Unavailability of design guidelines hinders the construction industry in implementing modular technology. The purpose of this study is to analyze the critical success factors for modular construction of residential high-rise buildings applying risk-based management to improve project time performance. Forty-one Indicators were drawn from literature reviews and specialist interviews to conduct a sustainability evaluation. The survey was submitted to case project developers, designers, supervisors, and contractors in Indonesia, thereafter statistically analyzed using SPSS and risk management analysis with three stages: risk sources, risk drivers and risk causes. Critical success factors for drawing approvals have a considerable influence on modular construction among 15 other factors, followed by supply chain and design standardization. It is necessary to mitigate these risks to improve project time performance.

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

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.
