Abstract

Kawasan Industri Terpadu Batang (KITB) adalah salah satu pusat pertumbuhan ekonomi baru yang strategis. Namun, kawasan tersebut belum ada pembangunan gedung pengelolaan yang berfungsi untuk kantor pengelola (KITB). Sehingga, BUMN akan membangun Gedung Kantor Pengelola Kawasan Industri Terpadu Batang. Jenis struktur yang akan direncanakan menggunakan struktur beton bertulang yang tentunya berpanduan serta mengacu pada Standar Nasional Indonesia yang terbaru, yaitu SNI 2847-2019, SNI 1726-2019, SNI 1727-2020 dan SNI 2052-2017. Perencanaan dimulai dengan menentukan sistem struktur, merencanakan struktur atap, preliminary desain, perhitungan beban, memodelkan struktur dan analisis momen, perhitungan penulangan, merencanakan struktur bawa dan dilanjut merencanakan anggaran biaya (RAB) dan Time Schedule.Hasil dari pembahasan yaitu sebuah perencanaan struktur Gedung dengan spesifikasi diantaranya adalah Gedung dengan sistem rangka pemikul momen khusus (SRPMK), struktur atap baja (Baja profil / IWF), B-1 (850 x 550 mm), B-2 (700 x 500 mm), B-T (350 x 250 mm), BC-1 (500 x 350 mm), BA-1 (650 x 350 mm), BA-2 (500 x 250 mm), BA-3 (400 x 200 mm), K-1 (850 x 850 mm), K-2 (750 x 750 mm), K-L (400 x 400 mm), Dinding geser (Tebal 400 mm) dengan struktur bawah menggunakan pondasi dalam dengan menggunakan bored pile P-1 (D = 550 mm, Depth = 14,60 m), P-2 (D = 300 mm, Depth = 6,40 m) dan perencanaan anggaran biaya (RAB) serta Time Schedule.

Abstract

Welding has a very important role in engineering and metal production repairs. This is very reasonable because every construction can hardly be separated from metal which involves welding elements. Metal is widely used because it has several advantages, including being strong, rust-resistant, resistant to wear and tear and the raw materials are very economical. The development of technology and science has also had an impact on the increasing demand for metal connections of different types. Several industries that use joining by welding different types of metal include the transportation industry, car manufacturing, shipping and airplanes. One thing that can be done is connecting different types of metal which can be applied in the shipping industry. This research aims to determine the impact of variations in welding FCAW Grade A material 16 mm thick on ship deck insert plates. The use of Flux Core Arc Wellding (FCAW) is often found in the shipping industry. FCAW or what is usually called CO2 arc welding actually includes Metal Inert Gas (MIG) welding, only the protective gas is not only a noble gas such as Argon (Ar) but also CO2 gas or it could be a mixture of the two gases. The FCAW welding process is often used because the protective gas used is CO2 so it is suitable for use in welding steel construction. CO2 decomposes into CO and O2 when in contact with high temperatures. As a result of the high freezing speed, the CO gas produced is trapped in the metal which then forms cavities. Efforts are made to prevent this by providing a mixture of Si and Mn to the electrode so that no gas is trapped and no reaction occurs.
