DECISION MAKING OF HAND TRACTOR GEAR BOX DESIGNS
Ahmad Fatih FudhlaSystems Modeling Laboratory, Industrial Engineering Department, STT YPMRaya Ngelom 86, Taman, Sepanjang, Sidoarjo 61257, East Java, IndonesiaEmail: [email protected] keputusan dalam memilih desain pengembangan komponen Gear Transmission box (GTB) pada Traktor Tangan dilakukan dengan banyak kriteria. Berdasarkan diskusi Focus group dan brainstorming yang dilakukan oleh tim pengembangan produk, teridentifikasi tujuh kriteria yakni; Ketahanan material terhadap korosi, Kemampuan desain untuk diproses di lantai produksi, kemampuan desain dalam menahan beban operasi maksimum traktor tangan, pengaruh terhadap proses produksi komponen lainnya, biaya manufaktur, massa desain GTB, dan waktu proses. Kriteria tersebut dikelompokkan ke dalam kategori positif dan negative. Positif adalah kriteria yang nilainya semakin besar semakin baik, sedangkan negatif semakin kecil semakin baik. Terdapat tiga alternatif desain, yakni Desain Awal, Desain 1 dan Desain 2. Pemilihan dilakukan dengan metode Analytic Hierarchy Process (AHP). Evaluasi dilaksanakan terpisah untuk kedua kategori. Alternative terbaik adalah alternative yang memiliki nilai perbandingan terbesar antara nilai alternatif criteria positif dan negative.KataKunci: Analytical Hierarchy Process, Perbandingan Berpasangan, Perancangan dan Pengembangan Komponen ProdukABSTRACTDecision making on selection of hand tractor Gear Transmission Box (GTB) “Improvement Designs” is carried out according to many criteria. Based on the focus group and brainstorm performed by product-development teams, seven criteria are finally identified as follows; Material corrosion resistance, Manufacturability, The ability of the design to withstand the maximum load operation, influence on the other components process, manufacturing cost, mass of GTB design, and processing time. Those criteria are categorized into positive and negative characteristics. Positive criteria indicate that score which is the greater the better, by contrast, negative is the less the better. There are 3 alternatives namely Initial Design, Design 1 and Design 2. The selection is performed based on Analytic Hierarchy Process (AHP) Method. The evaluation is analyzed separately according to each category. The best alternative is the one which has the highest ratio between positive and negative criteria.Key Words: Analytical Hierarchy Process, Pair-wise Comparison, Component Design and Development
