Analisis Kinerja Supply Chain Management Terhadap Efisiensi Biaya Dan Waktu Pekerjaan Struktur Proyek SMPN 5 Abiansemal

Abstract

The application of  good material supply chain management will affect the success of a construction project. Based on observations made in the logistics process of reinforced concrete materials for the SMPN 5 Abiansemal project, problems were identified in the procurement process of several  material items. Therefore, the author intends to conduct a study of supply chain management performance on the project in question, so that SCM performance indicators can be improved to improve cost efficiency and time of project implementation. SCM performance measurement on reinforced concrete structure work of this project is carried out using the Supply Chain Operation Reference  (SCOR) method and indicator mapping using  the Analytical Hierarchy Process (AHP) method. The parameters used are 2 core SCM processes, namely Plam  and Source along with derivatives of performance attributes, namely reliability, responsiveness, and cost. There are 8 performance indicators that are assessed by data collection methods through the process of interviews, observations, and questionnaires. Based on the results of data processing, SCM's performance obtained a total value of 84.49 with a good predicate.  As for based on the normalization  value of snorm de boer, there are 2 indicators and 1 sub-indicator that get an average value, namely the raw  material planning accuracy  and source cycle time indicators and the lead time of reload  sub-indicator on K250 concrete material. In general, the SCM process on the project has positive implications on the cost aspect because it is lower than the bid price, with a total source cost of  Rp 1,840,081,000 While in the time aspect, especially the procurement of K-250 concrete needs to be improved because it requires a waiting time of 2.9 hours so that the casting time is calculated for 10 hours 24 minutes with overtime against the limit of working hours for 4 hours 14 minutes
