Abstract

Permasalahan proyek konstruksi, salah satunya sisa material yang berlebih. Pengoptimalan dan penurunan sisa material menjadi konsentrasi yang harus diperhatikan dalam sektor konstruksi yang berkelanjutan. Tujuan penelitian untuk mengetahui kuantitas sisa material yang ditimbulkan pada pekerjaan struktur dalam katagori comsumable waste. Data penelitian dibagi menjadi dua, yang pertama diperoleh dari observasi lapangan yang disertai pengamatan langsung untuk mengetahui kondisi eksisting proyek konstruksi. Yang kedua berupa dan data kuantitatif proyek yang berupa data pelaksanaan dan data rencana. Hasil penelitian menunjukkan bahwa waste material diakibatkan kuantitas volume rencana yang terlalu besar dari kondisi aktualnya sehingga waste yang dihasilkan dari perencanaan cukup besar. Sedangkan pada besi 8 (12.96 %) dan besi 16 (17.32 %) dikarenakan pemesanan yang dilakukan melebihi dari yang direncanakan sehingga secara tidak langsung akan menimbulkan sisa material.

Abstract

Currently, the construction sector is adopting the theory of production in the manufacturing industry, known as lean construction, to reduce waste and increase value. Last Planner System (LPS) has not been widely used and has good potential because the advantage of LPS is to identify a job along with obstacles to improve performance in a construction project. In the construction of Junior High School (SMP) Al-Falah, it has work obstacles due to erratic weather so that the project is delayed, the author conducts a field survey to analyze the actual progress in the field, LPS has work indicators / work flow to measure the extent to which work indicators can be realized properly, the LPS work flow are Master Plan, Phase & Pull Planning, Lookahead Planning, Constraints Analysis, Shielding Production, and Percent Plan Complete (PPC) as a standard for measuring whether project productivity is realized properly or not. In this study, the results of the implementation using LPS on the Al-Falah Junior High School construction project show that the lowest PPC can be seen in week 7, which is 0% because there is no work achievement so that the work is delayed, while in week 16 it can be seen that PPC has increased dramatically to 96%. Then after averaging the PPC of 51% which means that LPS has not been able to increase the reliability of planning above 70%, (Ballard, 2000).
