Penerapan Metode Fuzzy Analytic Network Process (FANP) Dalam Menentukan Lokasi Kantor Cabang Bank Baru di Kabupaten Nganjuk (Studi Kasus: Bank Negara Indonesia)

Application of the Fuzzy Analytic Network Process (FANP) Method in Determining the Location of New Bank Branch Offices in Nganjuk Regency (Case Study: Bank Negara Indonesia)

Penentuan lokasi kantor cabang bank merupakan kebijakan operasional yang bersifat strategis, sehingga perlu adanya analisis mendalam dalam memilih lokasi yang tepat. Pemilihan alternatif lokasi ditentukan berdasarkan bobot tiap alternatif dari yang tertinggi menuju terendah. Pemeringkatan dilakukan berdasarkan bobot subkriteria yang telah diolah menggunakan metode Fuzzy Analytic Network Process (FANP). Perhitungan bobot juga didasarkan adanya ketergantungan (dependency) baik inner dependence maupun outer dependence. Adanya keterkaitan antar subkriteria satu dengan yang lain menjadikan metode Fuzzy Analytic Network Process (FANP) lebih kompleks dibandingkan metode lainnya.

Berdasarkan perhitungan metode Fuzzy Analytic Network Process (FANP) diperoleh bobot dari tiap subkriteria, yaitu jumlah penduduk sebesar 8,62%, kepadatan penduduk sebesar 12,95%, luas tanah sebesar 4,65%, fasilitas keamanan sebesar 24,65%, ketersediaan utilitas publik sebesar 2,62%, jarak lokasi dengan pemukiman sebesar 12,53%, jarak terdekat antar sesama cabang sebesar 33,09%, dan jumlah pesaing sebesar 0,90%. Hasil simulasi penentuan lokasi kantor cabang diperoleh, yaitu peringkat pertama kecamatan ngronggot, peringkat kedua kecamatan berbek, peringkat ketiga kecamatan lengkong, peringkat keempat kecamatan pace, peringkat kelima kecamatan prambon, peringkat keenam kecamatan gondang, dan peringkat ketujuh kecamatan bagor.

Determining the location of bank branch offices is a strategic operational policy, so it requires in-depth analysis in choosing the appropriate location. The selection of alternative locations is determined based on the weight of each alternative from highest to lowest. Ranking is arranged based on the weight of sub-criteria The calculation of weights is also based on the existence of dependencies (dependency) both inner dependence and outer dependence. The existence of interrelationships between sub-criterias makes the Fuzzy Analytic Network Process (FANP) method more complex than other methods.

Based on the calculation of the FANP method, the weight of each sub-criteria is obtained, specifically the population is 8,62%, population density is 12,95%, land area is 4,65%, security facilities is 24,65%, availability of public utilities is 2,62%, location distance to settlements is 12,53%, the closest distance between fellow branches is 33,09%, and the number of competitors is 0,90%. The simulation results of determining the location of branch offices obtained, specifically the first rank is Ngronggot sub-district, the second rank is Berbek sub-district, the third rank is Lengkong sub-district, the fourth rank is Pace sub-district, the fifth rank is Prambon sub-district, the sixth rank is Gondang sub-district, and the seventh rank is Bagor sub-district.
