Abstract


A construction project cannot be separated from costs, time, human resources and natural resources. Every project implementer always wants to be able to complete a construction project at the most economical cost possible. But this must be done with techniques that have been tested for success. The cost-saving technique used must still pay attention to the quality, reliability, and usefulness of a building that is being worked on. One of the saving techniques that have been tested for success is value engineering.

In an alternative selection, an analysis of the advantages and disadvantages of the ideas obtained in the creative stage is carried out. The assessment factors carried out on the alternatives to be chosen are initial costs, aesthetics, implementation time, level of implementation, durability, level of comfort, and level of environmental friendliness. The alternative chosen is an alternative that has the highest assessment results in the analysis stage, then calculating the costs required in the next stage.

Work items that have the highest costs are on roof work with a total initial cost of Rp. 434,560,000.00. After value engineering carried out, it is obtained that the selected alternative is using a 0.35 mm zincalume roof with a savings of Rp. 183,123,584 of the initial cost. The savings are around 3.6% of the total cost of the analyzed structure. Thus, one of the objectives of value engineering application which is cost savings is achieved.

Economic benefit value of former mining land reclamation with dynamic system simulation
Arie Saputra

Teuku Umar University

Abstract


Restoring environmental balance, especially the ecology of Former Mining Land (FML), is very much needed in modern mining practices through land reclamation activities and become a level that can be used again (Dong WS et al, 2011). Reclamation of mining land is one of the most important activities carried out to overcome the contradiction between the mining process and the return of environmental balance. The return of FML environmental balance must also be accompanied by a calculation of the value of FML economic benefits for the community so that social balance and civilization can also be restored. Coal mining currently has a lot of impact on local communities (Franks et al., 2010; Worrall et al., 2009) both on economic and social growth in society and the environment (Bridge, 2004; Hilson, 2000). Consideration of economic values ??can be used as a benchmark in carrying out reclamation activities through the selection of trees and commodities with an agroforestry approach (Sullivan J and Amacher GS, 2013). The complexity of determining the economic benefit value of Former Mining Land Reclamation (FML) aside from the calculated value of economic analysis is the projected representation of values ??that have been calculated taking into account the differences in the dimensions of time when calculated with future practice. Through dynamic system simulations the calculated economic benefit value can be simulated when reclamation will be carried out for decades to come. Dynamic system simulations can also accommodate changes that will occur from the external side when the calculated economic benefit value will be realized at different times. In the end, balancing activities due to non-renewable exploitation of natural resources require a concept that can guarantee the sustainability of the benefits of former mining land (Meadow, 2004). The role of technology in making simulations related with LBT economic benefit variables is needed to make planning are suitable with the implementation. this concept can ensure the sustainability of economic and environmental values is maintained. According to Jun BW et al (2009), the benefits of mining as part of empowerment and the sustainability strategy of the benefits of former mining land can be done by determining the right time to create a different form of industrialization from the mine. So that this research is built on the concept of determining the sustainability of the mine through analysis of the value of simulated economic benefits for the future.
