Abstract

Technological innovation in the construction sector is needed not only aimed at faster construction but also environmentally friendly. Engineering the formwork system using aluminum is one of the technological innovations to accelerate development and adopt the 3R (Reuse, Reduce, and Recycle) concept. To support the use of aluminum formwork, an environmentally friendly supply chain activity management model is needed. The Green Supply Chain Management (GSCM) approach is one method that can reduce waste. This study analyzes the driving and inhibiting factors of GSCM using aluminum formwork in an apartment project in Semarang. The method of compiling this research used a qualitative method, where interviews were conducted which were then made into complete transcripts and grouped each opinion with a SWOT matrix approach. Based on the results of the SWOT analysis, 4 factors have a significant effect. Among these 4 factors, there are 2 driving factors, namely government regulations regarding environmental protection and commitment to protecting the environment, and 2 inhibiting factors, namely the availability of suppliers who implement GSCM practices in construction areas and require careful planning. The use of aluminum formwork can save costs up to 5.44% with a construction time of 6 days faster than conventional methods.

Abstract

Two generally method / tools which used in project construction management system in Indonesia and the name are CPM (critical part method) or network planning and Bar Chart. The system used general method called conventional management system. Nowadays, was appeared one of a new system which seldom to applied in Indonesia, it is called LPS (last planner system). This research, researcher doing analyzed the differences between LPS and conventional management system. The result which obtained in this research are LPS dominated to accentuates team collaborative in the scheduling planning, resource allocation, control and enhance of work productivity, issue solved, regularly scheduling planning. Conventional management system more rely on the way CPM and Bar Chart working in that system with project manager decision. Planning of the schedule in this system doing by scheduling team. rescheduling in this system is not routine, it’s depend by construction progress. CPM and Bar Chart methods is influence on LPS. The both of methods was appeared in master scheduling, look a head scheduling, weekly work planning, shielding production, workable back log, percent plan completed and reliable promise process
