Abstract
Perkembangan kegiatan ekonomi suatu wilayah sebanding dengan peningkatan kebutuhan listrik tahunan pada wilayah tersebut. Untuk memenuhi peningkatan kebutuhan listrik di wilayah Palu dan sekitarnya, maka PT. Perusahaan Listrik Negara (Persero) membangun Pembangkit Listrik tenaga Uap (PLTU) Palu-3 dengan kapasitas 2x50 MW di Donggala, Sulawesi Tengah. Kontraktor pelaksana proyek PLTU Palu-3 ini adalah Konsorsium PT. Wijaya Karya (WIKA), Doosan Heavy Industries & Construction (DHI) dan Korea South-East Power (KOEN).
Proyek PLTU Palu-3 merupakan proyek berjenis EPC (Engineering Procurement Construction) sehingga melibatkan lebih banyak disiplin engineering. Tidak hanya civil dicipline, tetapi juga engineering process, project engineer, layout & piping, mechanical, equipment package, electrical, dan instrument. Scope pekerjaan pada divisi engineering khususnya civil dicipline yang dilakukan oleh PT. Wijaya Karya (Persero), Tbk. terdiri dari pekerjaan pekerjaan underground, structure, geotechnical, equipment foundation, marine structures dan architecture. Selain itu, tahapan pekerjaan yang dilakukan cukup menyeluruh mulai dari tahap perencanaan, perancangan, hingga konstruksi. Alur tahap perancangan dimulai dari site investigation dilanjutkan dengan pemodelan sesuai dengan design criteria & specification yang tertera dalam dokumen kontrak. Pemodelan dilakukan mengacu pada basic design drawing yang sudah ada untuk kemudian dituangkan dalam calculation report dan design drawing yang nantinya dijadikan acuan dalam membuat shop drawing. Setelah itu dilanjutkan dengan pekerjaan steel fabrication dan material take off dengan mengacu pada shop drawing dan kemudian dilakukan purchase order serta tahap terakhir yaitu production.
Beberapa jenis bangunan yang dirancang oleh PT. Wijaya Karya (Persero), Tbk. dalam proyek PLTU Palu-3 ini adalah struktur Belt Conveyor dan Chlorination Plant Building. Perancangan kedua bangunan tersebut dilakukan dengan menggunakan beberapa program bantu, diantaranya yaitu Autocad untuk gambar 2D, Navis untuk gambar 3D, SAP2000 untuk analisa pembebanan, AFES untuk analisa pemodelan pondasi, RAM Connection & IDEA StatiCa untuk analisa pemodelan joint connection.
===================================================================================================
The development of economic activity in a region is proportional to the increase in electricity demand in that region. To meet the increasing demand for electricity in Palu and its surroundings, PT. PLN (Persero) built the Palu-3 Steam Power Plant (PLTU) with a capacity of 2x50 MW in Donggala, Central Sulawesi. The contractor for the PLTU Palu-3 project is a consortium of PT. Wijaya Karya (WIKA), Doosan Heavy Industries & Construction (DHI), and Korea South-East Power (KOEN).
The PLTU Palu-3 project is an EPC (Engineering Procurement Construction) type project, meaning that it involves more engineering disciplines. The engineering division in EPC Project consists of civil discipline, engineering process, project engineer, layout and piping, mechanical, equipment package, electrical, and instrumentation. The scope of work in the engineering division, especially in civil discipline carried out by PT. Wijaya Karya (Persero), Tbk., consists of underground work, structure, geotechnical, equipment foundation, marine structures, and architecture. In addition, the stages of work carried out are quite comprehensive, starting from the planning, design, and construction stages. The flow of the design phase starts with site investigation followed by modeling in accordance with the design criteria and specifications stated in the contract document. The modeling is carried out by referring to the existing basic design drawings, which will then be included in the calculation report and design drawings that will later be used as a reference in making shop drawings. After that, it was continued with steel fabrication work and material takeoff with reference to the shop drawings, and then a purchase order was made, and the last stage was production.
Several types of buildings designed by PT. Wijaya Karya (Persero), Tbk. in the PLTU Palu-3 project are the Belt Conveyor and Chlorination Plant Building structures. The design of the two buildings was carried out using several auxiliary programs, including Autocad for 2D drawings, Navis for 3D drawings, SAP2000 for loading analysis, AFES for foundation modeling analysis, RAM Connection & IDEA StatiCa for joint connection modeling analysis.
