Wuryanto, Nadya Ayuning (2017) Perancangan Group Technology Layout Untuk Mengurangi Jarak Material Handling Pada Lantai Produksi Perusahaan Manufaktur Lantai Kayu. Sarjana thesis, Universitas Brawijaya.
Abstract
Pemborosan manufaktur merupakan praktek manufaktur yang tidak produktif dan tidak diinginkan, yang dapat merugikan perusahaan. Oleh sebab itu, continuous improvement diperlukan untuk menghilangkan atau mencegah adanya pemborosan manufaktur. Perusahaan Manufaktur Lantai Kayu di Malang saat ini sedang berusaha untuk menghilangkan pemborosan yang terdapat di fasilitas manufakturnya. Salah satu dari pemborosan yang terjadi adalah transporting waste yang disebabkan oleh jarak material handling yang cukup jauh. Jarak material handling ini terutama dipengaruhi oleh kondisi layout dari fasilitas produksi. Fasilitas produksi belum menerapkan layout spesifik yang umumnya digunakan seperti process layout, product layout, fixed position layout atau group technology layout. Oleh karena itu, penelitian ini bertujuan untuk merancang relayout planning menggunakan konsep Group Technology untuk mengurangi jarak material handling di Perusahaan Manufaktur Lantai Kayu. Dalam perancangan layout Group Technology, pertama-tama sel manufaktur dibentuk menggunakan tiga macam metode heuristik, yakni Similarity Coefficient Method, Rank Order Clustering 1 dan Single-Pass Heuristic Algorithm. Metode Similarity Coefficient Method dan Rank Order Clustering 1 menghasilkan 3 sel manufaktur. Namun ukuran selsel tersebut terlalu besar untuk konsep Group Technology, sehingga hasil pengelompokan sel tersebut diolah lebih lanjut mengunakan Single-Pass Heuristic Algorithm. Ada beberapa batasan yang dipertimbangkan dalam algoritma ini seperti batasan kapasitas dan jumlah mesin dalam satu sel. Batasan-batasan tersebut tidak pernah dipertimbangkan pada kedua metode sebelumnya. Hasil dari Single-Pass Heuristic Algorithm menunjukan ada 13 sel yang terbentuk dari 37 total mesin. Langkah selanjutnya adalah memperhitungkan kebutuhan luas setiap sel, kemudian merencanakan tata letak layout menggunakan metode Systematic Layout Planning (SLP). Metode ini menggunakan derajat kedekatan dalam mengatur letak setiap mesin pada rancangan fasilitas. Setelah layout Group Technology berhasil dirancang, jarak material handling kembali dihitung. Hasil dari perancangan layout Group Technology dalam penelitian ini menunjukkan pengurangan jarak yang signifikan. Ada dua perbandingan jarak yang dilakukan dalam penelitian ini, pertama perbandingan jarak menggunakan routing sheet yang menghasilkan pengurangan jarak sebesar 1.468,96 m atau 53,46% dari total jarak awal, dan kedua perbandingan jarak menggunakan From To Chart yang menghasilkan pengurangan jarak sebesar 699,73 m atau 64,63% dari total jarak awal.
English Abstract
Manufacturing wastes is an undesirable and an unproductive manufacturing practices which can be costly for the company. Therefore, continuous improvement is needed in order to eliminate or to prevent manufacturing wastes. Wooden Floor Manufacturing Company in Malang is trying to eliminate wastes in their manufacturing facility. One of their wastes is transporting waste which caused by far distance of material handling. The distance of material handling is mainly influenced by the layout condition of the production facility. This facility has not yet implemented one of the specific layout which is commonly used as process layout, product layout, fixed position layout or group technology layout. Thus, this study aimed to design re-layout planning using Group Technology concept in order to reduce the material handling distance in Wooden Floor Manufacturing Company. In designing Group Technology layout, firstly manufacturing cells are being formed using three heuristic methods that is Similarity Coefficient Method, Rank Order Clustering 1, and Single-Pass Heuristic Algorithm. The Similarity Coefficient Method and Rank Order Clustering 1 resulted into 3 manufacturing cells. However, these cells’ sizes were too big for Group Technology concept, therefore it was calculated further using Single-Pass Heuristic Algorithm. There were several constraints which were considered in this algorithm such as capacity and machine number constraint in one cell. Such constraints were never considered in the previous methods. The result showed there were 13 cells formed from the total of 37 machines. The next step was calculating the space area needed for each cells then planning the layout using Systematic Layout Planning (SLP) method. This method uses the closeness degree in positioning each machine in the facility planning. After the Group Technology Layout successfully planned, the distance of material handling were recalculated. The result of Group Technology layout planning in this study showed a significant distance reduction. There were two distance comparisons conducted in this study, first the comparison of distance using routing sheet which resulted into 1.468,96 m or 53,46% reduction of the total initial distance, and second the comparison of distance using From To Chart which resulted into 699,73 m or 64,63% reduction of the total initial distance.
