Mustakim (2014) Implementasi Lean Six Sigma, Multi Atribut Failure Mode Analysis, dan Fuzzy Analitic Hierarchy Process untuk Mengidentifikasi Penyebab Potential Defect pada Produk Particle Board. Magister thesis, Universitas Brawijaya.
Abstract
Salah satu dari peningkatan produk yang dapat dilakukan dengan meningkatkan kegiatan yang memiliki nilai tambah bagi produk mereka ( value added ) dan menghilangkan berbagai pemborosan ( waste ), atau disebut lean Thinking, dalam penelitian ini, penulis menggunakan pendekatan untuk mengintegrasikan konsep Lean, Six Sigma, Multi Atribut Failure Mode Analisis , dan Fuzzy AHP untuk mengidentifikasi penyebab potensial Defect guna mengurangi produk defect pada produk Particle Board . Particel Board merupakan produk yang dibuat dari partikel-partikel kayu yang berbahan lignoselulosa (Komposit), yang diikat menggunakan perekat sintesis dengan dipanaskan. Papan partikel ini memiliki kelebihan dibanding kayu aslinya yaitu papan bebas dari mata kayu, tidak mudah retak dan pecah, ukuran, tebal dan kerapatan partikel dapat disesuaikan dengan standard tertentu, mudah di bentuk, memiliki sifat isotropis, Akan tetapi itu juga memiliki Kelemahan yaitu stabilitas dimensi yang rendah, dan selalu terjadi Potential Defect. Potential Defect yang terjadi meliputi : Blister , gembur, crack , Paper Stripe , Kurang Amri , Noda Oli, Problem Dimensi dan Noda Resin. Dari hasil analisa regresi dapat diketahui bahwa Variabel Independen (P otential Defect ) memiliki pengaruh sangat signifikan terhadap jumlah produksi, yang itu terlihat pada defect dengan bobotnya yang tertinggi disebut sebagai blister. Jadi dalam penelitian ini, penulis tertarik untuk mengkaji defect Blister. Faktor Penyebab Blister terdiri dari faktor mesin, manusia, material dan metode ditemukan sebanyak 17 Cause yaitu Operator tidak disiplin melaksanakan SOP (Cause A), Kurang Kontrol Mat Weight (Cause B), Menggunakan Recipe yang tidak sesuai dengan parameter (Cause C), Gap Knife Flake terlalu besar (Cause D), Seting temperature kurang tinggi (Cause E), Nozle Glue dan Hardener buntu (Cause F), Speed Tinggi (Cause G), Suction Forming Kotor (Cause H), MC terlalu tinggi (Cause I), Persentase konsumsi resin rendah (Cause J), Kondisi Mat Weigth Forming bervariasi (Cause K), Kadar Dust terlalu tinggi (Cause L), Ukuran Flaker terlalu besar (Cause M), PH dan resin Content tadak Standard (Cause N), Bahan baku heterogen (Cause O), Standar parameter produksi tidak sesuai dengan kondisi saat ini (Cause P), Metode pengoperasian dan setting mesin tidak sesuai dengan SOP dan parameter produksi (Cause Q), berdasarkan hasil analisa dengan menggunakan konsep pendekatan Lean, SiX Sigma, Multi Atribut Failure Mode Analisis dan FUZZY AHP berguna untuk mengidentifikasi Faktor material Cause M yaitu ukuran Flaker terlalu besar yang merupakan penyebab kegagalan potensial dengan bobot tertinggi yaitu sebesar 0,087, maka, ini bisa diambil tidakan dengan penyesuaian ukuran pada output mesin Chiper dan melakukan penyesuaian pada Gap knifering pada mesin Flaker, sehingga dapat menurunkan potential defect sebesar 39.5 %.
English Abstract
One of increasing in product can be undertaken by working up activity that it has value added for each ir products and getting rid of various kind of extravagances, or it is called by Lean Thinking. In this research uses An approach to integrate concept of Lean Six Sigma, Multi Attribute Failure Mode Analysis and Fuzzy AHP is to identify cause of Potential Defect to reduce defect product on particle board product. Particle Board is a product made of particle wood which it has a lignocellulosic (composite) and it is bound by using of adhesive syn sis to be heated. particle board has an excess better than pristine wood, that it is an exempt board of snarl, it is not easy to crack and crash, have a size and thick, moreover, density of particle is able to be adapted with a specific standard, it is easy to be designed, has a feature of isotropic, however, it has susceptibility that is low in stability dimension and always come to pass to Potential Defect. Potential Defect encompasses: Blister, friable, crack, Paper Stripe, less emery, oil stains, Dimension Problem and Resin Stains. From results of regressive analysis, it performs that independent variable (Potential Defect) takes an important role to mount of production that it can be stared to Defect which has a high quality. Fur rmore, defect is called as blister. So, in this research, writer is interested to study defect blister. causative element of blister itself consists of some elements. y are machine factor, human, and material elements. re are 17 elements that found in it. y are operator which is not discipline to do SOP (Cause A), Less Control Mat Weight (Cause B), use an unacceptable recipe with a parameter (Cause C), Gap Knife Flake is oversize (Cause D), Temperature Setting less high (Cause E), Nozzle Glue and Hardener clogged (Cause F), high speed (Cause G), Suction Forming is grubby (Cause H), MC is exorbitant (Cause I), low percentage of resin consumption (Cause J), A various of Mat Weight Forming Condition (Cause K), level of dust is swollen (Cause L), size of flaker is oversize (Cause M), Resin and PH Content is not suitable with standard (Cause N), heterogeneous materials (Cause O), Standard Parameter Production is not appropriate with condition today (Cause P) operation methode and machine setting is not accordance with SOP and Parameter Production (Cause Q), according to result of analysis in using concept of approachment Lean, Six Sigma, Multi Attribute Failure Mode Analysis and FUZZY AHP is useful to identify ( element M) that it has over size. So that, it is able to cause failure of potential defect with a good quality that it is as big as 0,087. So, it can be stated that conformation of standard to output chipper machine and do a compliance to Gap knife ring to Flaker machine, so that it is able to reduce potential defect to tune of 39,5%.
