ABSTRAK Ghazi Fauzan, 2025. Analisis Perencanaan Pengadaan Bahan Baku dalam Mengatasi Kekurangan Material pada Produksi Forging Casting Brake Beam dengan Metode Material Requirement Planning (MRP) pada PT Surya Pratama Logam. Tugas Akhir, Program Studi DIII Administrasi Logistik, Universitas Logistik dan Bisnis Internasional. Pembimbing Utama: Eduard Sondakh, S.Si., M.T. Pembimbing Pendamping: Gayuh Minang Lati, S.T., MBA. Kata Kunci: Kekurangan Bahan Baku, Material Requirement Planning (MRP), Perencanaan Pengadaan, Produksi, Forging Casting Brake Beam. Forging Casting Brake Beam merupakan salah satu komponen kereta api yang diproduksi oleh PT Surya Pratama Logam. Perusahaan mengalami penundaan produksi akibat kekurangan bahan baku selama proses produksi. Rata-rata terjadi defisit 10,67% untuk as dan pelat baja serta 7,91% untuk besi cor antara Juli 2024 dan Juli 2025. Hal ini menunjukkan bahwa infrastruktur yang tersedia untuk perencanaan dan pengadaan bahan baku belum mampu memenuhi permintaan produksi secara efisien dan cepat. Penelitian ini menggunakan metode Material Requirement Planning (MRP) untuk mengatasi permasalahan tersebut. Pesanan produksi, struktur produk (Bill of Materials), informasi inventaris, dan waktu tunggu (lead time) diperhitungkan saat menggunakan MRP untuk merencanakan kebutuhan bahan baku. Melalui perhitungan kebutuhan kotor, ketersediaan bahan, serta penjadwalan pemesanan yang tepat, metode ini membantu perusahaan dalam menentukan jumlah dan waktu pemesanan bahan baku yang sesuai dengan kebutuhan aktual. Hasil penelitian menunjukkan bahwa penerapan metode Material Requirement Planning (MRP) secara efektif mampu membantu perusahaan dalam menentukan jumlah dan waktu pemesanan bahan baku secara tepat. Untuk memenuhi permintaan vendor diperlukan produksi sebanyak 60 unit Forging Casting Brake Beam, MRP menghasilkan kebutuhan bahan baku yang spesifik, antara lain: Main Beam sebanyak 60 unit, Brake Head 120 unit, Brake Lever Pin 60 unit, Baut Mur Baja 240 unit, Cotter Pin 120 unit, Besi Cor 1.360 kg, Plate Baja 60 unit, dan As Baja 62 unit. Dengan memperhitungkan ketersediaan stok dan lead time antara 1 hingga 2 minggu, metode ini mampu menghindari kekurangan bahan baku, mengoptimalkan biaya persediaan, serta meningkatkan efisiensi proses produksi secara menyeluruh. Dengan demikian, MRP terbukti menjadi solusi yang tepat dalam mendukung kelancaran dan ketepatan produksi di PT Surya Pratama Logam. vii ABSTRACT Ghazi Fauzan, 2025. Analysis of Raw Material Procurement Planning to Overcome Material Shortages in Forging Casting Brake Beam Production Using the Material Requirement Planning (MRP) Method at PT Surya Pratama Logam. Final Project, Diploma III Logistics Administration Study Program, International Logistics and Business University. Primary Supervisor: Eduard Sondakh, S.Si., M.T. Supervisor: Gayuh Minang Lati, S.T., MBA. Keywords: Raw Material Shortage, Material Requirement Planning (MRP), Procurement Planning, Production, Forging Casting Brake Beam. Forging Casting Brake Beam is a railway component produced by PT Surya Pratama Logam. The company experienced production delays due to raw material shortages during the production process. An average deficit of 10.67% occurred for steel axles and plates and 7.91% for cast iron between July 2024 and July 2025. This indicates that the existing infrastructure for raw material planning and procurement is not yet capable of meeting production demand efficiently and quickly. This study uses the Material Requirement Planning (MRP) method to address this issue. Production orders, product structure (Bill of Materials), inventory information, and lead times are taken into account when using MRP to plan raw material requirements. By calculating gross requirements, material availability, and accurate order scheduling, this method helps companies determine the quantity and timing of raw material orders that align with actual needs. The results of the study indicate that the effective application of the Material Requirement Planning (MRP) method can help companies determine the quantity and timing of raw material orders accurately. To meet vendor demand, the production of 60 units of Forging Casting Brake Beam is required. MRP produces specific raw material requirements, including: 60 units of Main Beam, 120 units of Brake Head, 60 units of Brake Lever Pin, 240 units of Steel Bolts and Nuts, 120 units of Cotter Pin, 1,360 kg of Cast Iron, 60 units of Steel Plate, and 62 units of Steel Axle. By taking into account stock availability and a lead time of between 1 to 2 weeks, this method is able to avoid raw material shortages, optimize inventory costs, and improve the efficiency of the overall production process. Thus, MRP has proven to be the right solution in supporting the smooth and precise production at PT Surya Pratama Logam.
