Abstract

Nickel is one of the minerals that is in demand by many parties, especially now that nickel is an important ingredient in the promotion of green energy because it is a component of electric vehicle production. According to the International Energy Agency (IEA), nickel demand in 2020 is 2,340.56 metric tons and according to the sustainable development scenario, nickel demand is projected to reach 6,265.74 metric tons which can account for 60% of total clean energy in 2040. However, the impact of this mining is a case of environmental damage such as road damage, water pollution, air pollution, land damage. Based on the Regulation of the Minister of Environment and Forestry Number 6 of 2021 concerning Procedures and Requirements for the Management of Hazardous and Toxic Waste Materials, the determination of the status of B3 waste is carried out through characteristic tests which include explosive, flammable, reactive, infectious, corrosive and/or toxic. TCLP test, LD50 toxicology test and sub-chronic toxicology test were performed to determine the toxic properties of B3 waste. The method used in this study is a concrete mix design job as an advanced processing of cement/concrete manufacturing. This research is experimental where this research aims to determine the relationship between the compressive strength of concrete and the compression testing machine with the concrete mix design method. The test specimen made in this experiment was in the form of a concrete cylinder with a height of 300 mm and a diameter of 150 mm totaling 150 samples with a fermentation period of 7,14,28,54 and 90 days. Carbon sulfur and dirty sulfur are determined as non-B3 waste based on the results of the TCLP test so that further processing and utilization can be carried out. Carbon sulfur & dirty sulfur from the results of laboratory tests showed that the toxicity characteristics leaching procedure (TCLP) and total concentration (TK) values did not exceed the Category B threshold according to PP22 of 2021 so that it was non-B3 waste so that it could be utilized. For the 90-day fermentation period, the highest compressive strength is cs+ds 5%, cs+ds 10% of 179.4 kg/m², 170.3 kg/m². With an economic value for each Cs+Ds 5% of IDR 34,042.50, Cs+Ds of 10% of IDR 36,941.14 and Cs+Ds of 15% of IDR 39,495.52.

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

This study examines Transit Oriented Development (TOD) in South Tangerang City, focusing on the Rawa Buntu TOD area. TOD aims to integrate public transportation modes with non-motorized networks, fostering sustainable mobility and reducing dependence on private vehicles. The research highlights the policy framework and infrastructural developments supporting TOD in South Tangerang, such as Regional Regulation No. 9 of 2019 and Mayor Regulation No. 118 of 2022. Employing mixed methods, including surveys, field observations, literature reviews, and spatial analysis, the study assesses the transportation system and infrastructure conditions. Results show that most roads in South Tangerang are in good condition, with significant movement patterns between key districts. Rawa Buntu Station, a strategic transit node, demonstrates robust integration with various transportation modes, serving approximately 11,000 passengers daily. The study concludes that Rawa Buntu TOD area boasts comprehensive transportation infrastructure and efficient services, enhancing urban connectivity and sustainability.
