Abstract

Nowadays, environmental issues in construction project activities that were previously ignored have become major problems as they trigger global warming. Consequently, green construction as a concept of sustainable development has begun to be implemented. It is sort of an effort to minimize the impact of damage to the environment. The construction project of the Tulungagung-Trenggalek southern route carried out material recycling from construction waste to top foundation layer material. The material processing will have an impact on the construction implementation. Therefore, it is necessary to have a study on a comparative analysis of costs, time, and environmental impacts on the work of the top layer using recycled materials and the cut-and-fill method. After using recycled materials, the cost was IDR 2,637,312,551.00, while the cut-and-fill method cost was IDR 2,535,283,401.00. The recycling method took 20 days, whereas the cut-and-fill method took 37 days. Material waste reached 5729.27 tons by the recycle method and 46586.82 tons by the cut-and-fill method. The recycling method caused emissions of 52774.4 kgCO2/liter, while the cut-and-fill method brought in 59935.34 kgCO2/liter. In conclusion, the recycling method can be categorized as a green construction method because it produces fewer emissions and waste than the cut-and-fill method. The recycling method can reduce the impact of environmental damage.

Abstract

Mamaq is a traditional practice passed down through generations of the Sasak tribe. Analysing the idea of science in relation to the physical and chemical alterations in the Sasak tribe’s mamaq tradition is the goal of this study. This research uses a qualitative approach with a descriptive research type to explore in-depth knowledge about the mamaq tradition of the Sasak tribe. Direct observation and interviews were used to get data from community leaders and cultural figures, as well as secondary data from various relevant written sources. The analysis results found several scientific concepts in the mamaq tradition related to physical and chemical changes, including: 1) The betel nut that is cut, there is a physical change in the structure of the betel nut from a round shape to small pieces. 2) The betel leaves that are folded, there is a change in the shape of the leaves into a square fold. 3) There is a transition from a solid to a liquid texture in the ground mamaq substance. 4) The combination of mamaq components, where the chemicals in the finely ground substances generate a red colour. Thus, it may be said that the physical and chemical changes in the Sasak tribe’s mamaq tradition contain a scientific concept
