Production control, inventory and distribution is an important factor in trading activities. These three factors are discussed in a system called Supply Chain Management (SCM). Procurement of goods from a company or trading business related to suppliers. In some cases, there are several supplier that can be assessed by considering certain factors. In certain cases, the data from several factors that are considered are uncertainty, so the fuzzy approach can be used. The MINMAX Multi Choice Goal Programming model can be used to solve fuzzy supplier selection problems with linear membership function. It can be applied to selecting supplier of Brastagi Oranges. There are four suppliers, namely Jaya, Mako, Baros.  Gina. There are three factor to consider, cost, quality and delivery. The decision maker select the best supplier for ordering 17000 kg Brastagi oranges. The results, the best supplier is Gina with an order quantity of 10000 kg and Mako with a total order of 7000 kg

Supplier selection process was become important consideration to improve the efficiency of procurement department because the raw material cost could reach 70% of product cost.  The supplier selection process was multi-criteria problem involving qualitative and quantitative factors. The company often experienced shortage of  good quality tamarind  with a cheap price which companies often reject order from customers. Therefore the company should make a selective supplier selection and allocation of orders for optimum results by considering both qualitative and quantitative factors that can minimize the cost of purchase, maximizing the weight of suppliers and minimize the total defect order. This research will integrate supplier weight from Fuzzy Analytic Hierarchy Process and Goal Programming model for the final decision of supplier selection and allocation of orders. By running goal programming model give solution better than order allocation current model where it could reduce total cost of purchasing at Rp 130.000.000 to Rp 127.700.000 and reduce total of defect order at 4%  to 0,87%.

Pemilihan pemasok seringkali merupakan permasalahan multi kriteria yang melibatkan faktor kualitatif dan kuantitatif. UD Virgo Snack Bersinar merupakan perusahaan pembuat keripik buah-buahan yang berlokasi di Malang. Perusahaan sering mengalami kekurangan pasokan buah nangka yang mengganggu jalannya proses produksi, sehingga perlu dilakukan pemilihan pemasok buah nangka secara selektif dengan mempertimbangkan kriteria-kriteria yang ditetapkan oleh perusahaan dan pengalokasian pesanan kepada supplier terpilih. Pada penelitian ini akan mengintegrasikan bobot pemasok dari hasil Analytic Hierarchy Process dengan model � PreemptiveGoalProgramminguntukmenentukanprioritasdankuantitaspesananPreemptive Goal Programming untukmenentukanprioritasdankuantitaspesanan untuk menentukan prioritas dan kuantitas pesanan kepada pemasok. Model diformulasikan untuk mencapai dua fungsi tujuan yaitu maksimasi total nilai pembelian dan minimasi total biaya pembelian serta mempertimbangkan batasan kapasitas pemasok dan pemenuhan kebutuhan buah nangka. Dari hasil running model goal programming diperoleh supplier dari Semarang akan memasok buah nangka sebanyak 7,5 ton pada periode November 2013 – Januari 2014 dan kekurangan pasokan untuk menutupi kebutuhan buah nangka dipasok oleh supplier dari Tajinan.Kata kunci: buah nangka, pemasok, bobot pemasok, goal programming, analytic hierarchy processABSTRACTConsidering that raw material cost could reach 70% of product cost, supplier selection process was become important consideration to improve the efficiency of procurement department. The supplier selection process was multi-criteria problem involving qualitative and quantitative factors. UD Virgo Bersinar was one of fruit chips manufacturer located in Malang. The company often experienced shortage of jackfruits which interrupt production process. Thus, it was necessary to choose its supplier by considering company’s criteria and order allocation of selected supplier. This research would integrate supplier weight from Analytic Hierarchy Process and Preemptive Goal Programming model to determine priority of supplier and order quantity to the supplier. The model was formulated to achieve two objective functions, namely maximizing total value of purchasing and minimizing total cost of purchasing, by considering capacity of supplier and fulfillment of jackfruit. By running goal programming model, it was concluded that supplier from Semarang would supply 7.5 ton of jackfruit in November 2013-Januari 2014 and deficiency of needs would be supplied by supplier from Tajinan.Keywords: jackfruit, supplier,supplier weight, goal programming, analytic hierarchy process
