Abstract

Pemilihan supplier merupakan salah satu hal penting yang menjadi bagian dari usaha untuk meningkatkan daya saing sebuah perusahaan. PT. Jaya Salvage Indonesia merupakan sebuah perusahaan swasta yang bergerak di bidang jasa penyelamatan dan pekerjaan di bawah air. Dalam mendapatkan peralatan menyelam yang berkualitas baik, PT Jaya Salvage Indonesia melakukan pembelian dari tiga supplier. Harga barang yang mahal, namun masih terdapat barang yang mempunyai kerusakan/kecacatan saat barang sampai, merupakan permasalahan yang sering dihadapi oleh PT. Jaya Salvage Indonesia. Performance dari ketiga supplier berdasarkan penilaian manager operasional dianggap sama, sehingga secara subjektif tidak dapat diketahui supplier mana yang memberikan performance terbaik. Perlu dilakukan analisis mengenai pemilihan supplier yang dapat mengakomodasi pengukuran performa supplier. Analisis pemilihan supplier dilakukan berdasarkan sembilan kriteria. Analisis pemilihan supplier dilakukan dengan melakukan survei kepada 33 orang pegawai baik penyelam maupun tim internal. Berdasarkan analisis menggunakan metode One-Way MANOVA diperoleh bahwa terdapat perbedaan rata-rata hasil penilaian ketiga supplier berdasarkan sembilan kriteria. Berdasarkan analisis dengan metode regresi logistik multinomial diperoleh bahwa kriteria yang berpengaruh adalah kriteria harga, kualitas, fasilitas dan kapasitas produksi, dan manajemen dan operasi. Kecendurungan untuk memilih supplier 3 merupakan yang tertinggi dibandingkan dengan kecenderungan untuk memilih supplier lain. ============================================================================================================ Supplier selection is one of the important things that are part of the effort to improve the competitiveness of a company. PT. Salvage Jaya Indonesia is a private company that deals on salvaging and underwater work. In a purpose for getting a good quality diving equipment, PT Jaya Salvage Indonesia purchased diving equipment from three suppliers. The prices is too expensive, but there are items that have damage / disability when the goods arrive, is a problem often faced by PT. Salvage Jaya Indonesia. So, there is a need to do analysis on supplier selection that can accommodate measurement of supplier performance. Analysis of supplier selection is based on nine criteria. Analysis of supplier selection is done by surveying the 33 employees of both divers and internal teams. Based on an analysis using One-Way MANOVA showed that there are differences in average three supplier assessment results based on nine criteria. Based on the analysis by multinomial logistic regression showed that there are some criteria that influence the model. That criteria are price, quality, facilities and production capacity, and management and operation. Tendency to choose supplier 3 is the highest compared with the tendency to choose another supplier.
