Abstract
Penelitian ini mengajukan perbaikan tata letak mesin pada Divisi Material
di suatu perusahaan sepeda. Hal ini dikarenakan penempatan mesin baru yang
kurang tepat dan dapat mengurangi efisiensi dalam proses
produksi. Perbaikan tata letak dilakukan dalam kerangka kerja
(SLP) berdasarkan konsep untuk meningkatkan
efisiensi proses produksi yang memiliki level variasi cukup tinggi.
Pada tahap pengumpulan data waktu, dilakukan secara
komprehensif. Pada tahap pengelompokan mesin, teknik yang digunakan adalah
di mana koefisien yang digunakan adalah ,
, dan . Tahap prediksi luas sel dilakukan dengan menggunakan
teknik regresi linear. Tahap pengembangan tata letak dalam skala makro
dilakukan dengan teknik reguler (SA) dan
(MOSA).
Di bagian akhir, diperoleh lima tata letak usulan. Kelimanya memiliki
efektivitas pengelompokan yang lebih baik dari tata letak awal (
= 0.66; = 0.24). Tata letak usulan 1, 2, dan 3
merupakan usulan dengan pengelompokan mesin terbaik ( =
0.80; = 0.51). Tata letak usulan 1 merupakan usulan terbaik
untuk kriteria aliran material (aliran material mingguan = 45,713.28 kali.cm). Tata
letak usulan awal merupakan usulan terbaik untuk kriteria ( =
558.12 cm). Tata letak usulan 2 merupakan usulan terbaik untuk kriteria
( = 152.29 cm). Apabila performa setiap tata letak usulan pada tiap kriteria
dirangking dan diberi skor, tata letak usulan 2 dan 4 merupakan dua usulan
dengan rataan skor tertinggi, yakni 0.78 dan 0.67 dari total skor maksimal 1. / This research proposes a facility layout improvement in Material Division
in a bicycle company. This is due to the inefficient placement of new machines
and thus, can affect efficiency in material handling. Layout improvement is being
held with Systematic Layout Procedure (SLP) as the framework, based on group
technology concept to improve efficiency in production system with high level of
product variation.
There are several stages conducted in this research. In cycle time research,
a comprehensive time study is being held. In machine grouping, similarity
coefficient method is conducted, in which the writer uses three different
coefficients: Jaccard, Ochiai, and Kulczynski. To predict the area of cells, linear
regression method is used. In the macro development stage, a regular Simulated
Annealing (SA) and Multi Objective Simulated Annealing (MOSA) are
implemented.
In the end, there are five proposed layouts with a better score for machine
grouping criteria compared to the original layout (grouping efficiency = 0.66;
grouping efficacy = 0.24). Proposed layout 1, 2, and 3 are the best layout for
machine grouping criteria (grouping efficiency = 0.80; grouping efficacy = 0.51).
Proposed layout 1 is the best layout for material flow criteria (material flow/week
= 45,713.28 times.cm). Proposed layout from the supervisor is the best layout for
movement criteria (movement = 558.12 cm). Proposed layout 2 is the best layout
for unity criteria (unity = 152.29 cm). However, if performance of each proposed
layout is ranked and scored, proposed layout 2 and 4 are the two layouts with the
highest mean of rank weight (rank weight for proposed layout 2 = 0.78; rank
weight for proposed layout 4 = 0.67).
