EVALUASI PENGENDALIAN MATERIAL PADA PEMBANGUNAN GEDUNG RUMAH SAKIT JIWA PROFESOR DR. ILDREM SIMALINGKAR KOTA MEDAN

Abstract

In building construction activities, material procurement is an aspect that is highly considered by service providers. The use of material requires integrated control because the quality of the material greatly affects the results of the work being done. If the material used is of low quality, this can ccause failure in construction work. Therefore, proper material planning and control are essential. Thus it is important to implement good material inventory management so that inventory policies can ensure the availability of raw materials is met at minimal cost. Based on thic, the idea arose to conduct research on the suitability of the MRP method in material design and control. This study aims to understand how the material control process is in the construction of a Mental Hospital Building using the MRP method and to compare the results of material inventory control between the MRP method and the realization in the field. From this study, it is concluded that the control of material needs and inventory in the case study of the Prof. Dr. Muhammad Ildrem Mental Hospital Building using the MRP method shows that the material inventory is always more than the need. As a result, the work does not experience a shortage or accumulation of materials, so that construction can be completed. Conversely without using the MRP method, the material inventory (cement, sand, reinforcing, sand, reinforcing steel and red brick) is insufficient, resulting in delays in project completion.
