Abstract

Pada proses pergudangan di PT X terdapat beberapa permasalahan, salah satunya yaitu
penyimpanan sparepart yang menumpuk karena perusahaan tidak menerapkan sistem
manajemen persediaan dan forecasting dengan baik. Pada Februari 2021, dari 252 jenis
sparepart yang terdapat pada gudang. Hanya 46 dari jenis sparepart yang memiliki
permintaan pada bulan tersebut atau sebesar 18%, mengindikasikan bahwa mayoritas
dari sparepart menjadi deadstock di gudang. Terdapat indikasi waste waiting pada
kegiatan unloading dan storaging dikarenakan kurangnya tenaga kerja pada gudang
mengakibatkan barang yang datang diletakkan pada lantai gudang sebelum
dipindahkan ke rak yang bersangkutan. Kondisi peletakan dan penataan barang yang
tidak rapi membuat lead time proses pergudangan lebih lama dikarenakan pekerja perlu
mencari barang terlebih dahulu serta melakukan pergerakan tambahan untuk
menggapai produk (waste motion). Dari permasalahan tersebut terdapat indikasi
kegiatan yang tidak memberi nilai tambah sehingga penulis menggunakan pendekatan
lean warehousing dengan tools Lean Matrix for Warehouse (LMW). Dari hasil
penelitian didapatkan bahwa area kritis pada gudang adalah lantai satu gudang
eksternal. Serta rekomendasi perbaikan dengan rank of action priority tertinggi adalah
pelaksanaan rekrutmen dan training pada pekerja yang diproyeksikan mampu
mengurangi lead time proses pergudangan hingga 68% pada gudang internal dan 45%
pada gudang eksternal.
=======================================================================
In the warehousing process at PT X, there are several problems, one of which is
spareparts’ storage that accumulates because the company does not implement a good
inventory management and forecasting system. In February 2021, of the 252 types of
spare parts in the warehouse. Only 46 of the spare parts had demand for that month or
18% in total. Indicating that the majority of spare parts were deadstock in the
warehouse. There are indications of waiting in unloading and storage activities due to
the lack of manpower in the warehouse resulting in the goods coming to be placed on
the warehouse floor before being moved to the respective shelves. The condition of
placing and arranging items that are not neatly arranged makes the lead time of the
warehousing process longer because workers need to find the goods first and make
additional movements to reach the product (motion waste). From these problems, there
are indications of activities that do not provide added value, so the author uses a lean
warehousing approach with Lean Matrix for Warehouse (LMW) tools. From the results
of the study, it was found that the critical area in the warehouse is the first floor of the
external warehouse. As well as recommendations for improvement with the highest
rank of action priority is the implementation of recruitment and training for workers
which is projected to be able to reduce the lead time of the warehousing process by up
to 68% on internal warehouse and 45% on internal warehouse
