Abstract

PT Gemala Kempa Daya adalah perusahaan manufaktur yang bergerak dibidang komponen otomotif. Untuk menunjang kelancaran aktivitas dalam perusahaan, PT Gemala Kempa Daya memiliki warehouse finished goods yang khusus untuk menyimpan pressed part. Namun, terdapat aktivitas yang tidak bernilai tambah pada warehouse finished goods seperti pekerja yang harus berulang-ulang memindahkan dan menata barang. Selain itu, pekerja yang harus mencari lokasi untuk tempat penyimpanan produk saat produk masuk ke warehouse dan juga mencari lokasi produk disimpan saat produk diperlukan untuk dikirim. Untuk menyelesaikan permasalahan tersebut, perlu dilakukan reduksi dan/atau eliminasi kegiatan yang tidak bernilai tambah dengan pendekatan lean warehousing. Tools yang digunakan untuk mengidentifikasi waste adalah Value Stream Mapping dan Process Activity Mapping. Selanjutnya, dilakukan identifikasi waste kritis dengan tools Genba Shikumi, dan mencari akar penyebab terjadinya waste kritis dengan 5 Why’s Analysis. Berdasarkan temuan akar penyebab terjadinya waste, akan diusulkan rekomendasi perbaikan berupa penggunaan polybox sebagai wadah untuk menyimpan finished goods, perancangan sistem barcode untuk mencatat informasi terkait stok, lokasi dan beberapa informasi penting lainnya, serta perancangan tag barang yang terintegrasi dengan barcode. Dengan usulan perbaikan tersebut, dapat mengliminasi non value added activity dan diestimasi dapat mereduksi waktu proses warehouse finished goods sebesar 3181 detik.

PT Gemala Kempa Daya is a manufacturing company engaged in the automotive sector. To support the company activities, PT Gemala Kempa Daya has a finished goods warehouse specifically for storing pressed parts. However, there are activities that do not add value to the finished goods, such as workers who have to repeatedly move and arrange goods. In addition, workers must find locations for product storage when products enter the warehouse and find locations for products to be stored when products are needed to be shipped. To solve these problems, it is necessary to reduce and/or eliminate non-value added activities using a lean warehousing approach. Value Stream Mapping and Process Activity Mapping tools will be used to identify waste. Next, identify critical waste with Genba Shikumi tools and identify root causes of critical waste using 5 Why's Analysis. Based on the findings of the root causes of waste, recommendations for improvement will be proposed such as using polybox as containers to store finished goods, designing a barcode system to record information related to stock, location and some other important information, as well as designing goods tags that are integrated with barcodes. With the proposed improvement, it is possible to eliminate non-value added activities and it is estimated that it can reduce the processing time of the warehouse finished goods by 3181 seconds.
