Abstract

Penelitian ini diawali dengan identifikasi masalah yang ada pada Gudang 3 di PT. Steel
Pipe Industry of Indonesia unit 3. Yaitu berawal dari inisiatif Divisi Produksi (Production
Department) yang menginginkan pengangkutan pipa-pipa dengan total bobot 2 ton
menggunakan overhead crane dengan alat bantu caddy pipe crane atau biasa disebut lifting
beam mampu mengangkat hingga 5 Ton. Penelitian ini bertujuan untuk meningkatkan efisiensi
proses pengangkutan pipa-pipa yang telah siap untuk diantar ke konsumen dengan
mengantisipasi potensi kegagalan struktural pada caddy pipe crane.
Metode yang digunakan adalah dengan membuat desain 3D model caddy pipe crane
yang lama menggunakan software solidworks dengan material ASTM A36 untuk frame caddy
dan hook dan AISI 1020 untuk holder dan pin, kemudian peneliti akan merancang desain caddy
pipe crane yang baru dengan material ASTM A572 untuk holder dan frame caddy dan AISI
1045 untuk pin dan hook. Kemudian dilakukan simulasi static structural menggunakan
software ansys untuk mendapatkan nilai maximum von mises stress dan titik lokasinya dengan
kriteria safety factor ≥3. Setelah itu akan dilakukan perbandingan antara desain caddy pipe
crane desain lama dan desain baru.
Static structural Caddy pipe crane desain lama didapatkan maximum von mises stress
senilai 290.44 MPa dan berlokasi di holder dengan tegangan ijin material AISI 1020 senilai
68.3 MPa dan material ASTM A36 senilai 83.3 MPa. Kemudian caddy pipe crane desain baru
didapatkan maximum von mises stress senilai 43.313 MPa dengan tegangan ijin senilai 103.3
MPa. Desain lama dikatakan tidak aman dikarenakan nilai maximum von mises stress melebihi
tegangan ijin material dan nilai safety factor yang tidak memenuhi kriteria, sedangkan caddy
pipe crane desain baru dikatakan aman dikarenakan nilai maximum von mises stress di bawah
tegangan ijin material dan nilai safety factor yang memenuhi kriteria yaitu ≥3.

This research begins with the identification of problems that exist in Warehouse 3 at PT
Steel Pipe Industry of Indonesia unit 3. It started from the initiative of the Production Division
(Production Department) which wanted to transport pipes with a total weight of 2 tons using
an overhead crane with a caddy pipe crane or commonly called a lifting beam capable of lifting
up to 5 tons. This research aims to improve the efficiency of the process of transporting pipes
that are ready to be delivered to consumers by preventing potential structural failures in the
caddy pipe crane.
The method applied is by making a 3D design of the old caddy pipe crane model using
solidworks with ASTM A36 material for the caddy frame and hook and AISI 1020 for the
holder and pin, then researchers will design a new caddy pipe crane with ASTM A572 material
for the holder and caddy frame and AISI 1045 for the pin and hook. Then a static structural
simulation is performed using Ansys to determine the maximum von mises stress value and its
location point with a safety factor criterion of ≥3. After that, a comparison will be made between
the old and new design of the caddy pipe crane.
Static structural simulation of the old design caddy pipe crane obtained maximum von
mises stress is equal to 290.44 MPa and is located in the holder with the allowable stress of
AISI 1020 material is equal to 68.3 MPa and ASTM A36 material is equal to 83.3 MPa. Then
the new design caddy pipe crane obtained maximum von mises stress is equal to 43.313 MPa
with an allowable stress of 103.3 MPa. The old design is said to be unsafe because the maximum
von mises stress value is higher than the material allowable stress and the safety factor value
does not meet the criteria, while the new design caddy pipe crane is considered safe because
the maximum von mises stress value is below the material allowable stress and the safety factor
value meets the criteria, which is ≥3
