Abstract
The increasing demand for fresh water in Cilegon’s industrial area has driven PT Krakatau Tirta Industri (PT KTI) to construct a new Water Treatment Plant (WTP) with a capacity of 600 Lps. One crucial aspect of WTP operations is the availability of a safe and efficient Chemical Storage Facility. This research aims to design the layout of a new chemical warehouse to support the operations of the new WTP, considering land limitations and material flow efficiency. The method used is Systematic Layout Planning (SLP), which includes material flow analysis, activity relationship analysis (ARC and ARD), space requirement assessment, and evaluation of layout alternatives. Primary data were obtained through field observations and interviews with PT KTI personnel, while secondary data came from technical documents and existing facility designs. The study results in an optimized layout design of 276 m² from 322 m2 available area to capable of accommodating all activities including chemical receiving, storage, dilution, and distribution (for aluminium sulfate and lime milk). Additionally, Material Handling Cost (OMH) of Alumunium sulfate from Storage Area to Pouring Area with a value of IDR 1.654,-/meter for a total distance of 208 m/day. The proposed layout is able to optimize the distance of material transfer and enhances both safety and workplace comfort. This research is expected to serve as a reference for future facility layout planning in similar industrial contexts. Keywords: Facility Layout, Chemical Storage, Systematic Layout Planning, Material Handling Cost Peningkatan kebutuhan air bersih di kawasan industri Cilegon mendorong PT Krakatau Tirta Industri (PT KTI) untuk membangun New Water Treatment Plant (WTP) Krenceng berkapasitas 600 Lpd. Salah satu aspek penting dalam operasional WTP adalah tersedianya fasilitas Gudang Bahan Kimia yang efisien dan aman. Penelitian ini bertujuan untuk merancang tata letak fasilitas Gudang Kimia Baru yang dapat mendukung operasional WTP baru tersebut, dengan mempertimbangkan keterbatasan lahan serta efektivitas aliran material. Metode yang digunakan adalah Systematic Layout Planning (SLP), yang mencakup analisis aliran material, hubungan aktivitas (ARC dan ARD), kebutuhan ruang, dan hasil usulan layout. Data primer diperoleh melalui observasi lapangan dan wawancara dengan pihak terkait di PT KTI, sementara data sekunder berasal dari dokumen teknis dan desain eksisting. Hasil penelitian menghasilkan rancangan tata letak optimal dengan luas 276 m² dari luasan tersedia 322 m2 yang mampu mengakomodasi seluruh proses penerimaan, penyimpanan, pelarutan, dan distribusi bahan kimia (aluminium sulfat dan kapur cair) secara efisien. Selain itu, dilakukan perhitungan ongkos material handling (OMH) alumunium sulfat dari area penyimpanan menuju area penuangan dengan nilai sebesar Rp. 1.654,-/meter untuk total jarak 208 m/hari. Rancangan layout yang diusulkan mampu mengoptimalkan jarak perpindahan material dan meningkatkan keselamatan serta kenyamanan kerja. Penelitian ini diharapkan dapat menjadi acuan dalam perancangan fasilitas serupa di masa mendatang.
