MENENTUKAN FUNGSI FAKTOR RASIO TERHADAP KINERJA PERUSAHAAN MANUFAKTUR DENGAN MENGGUNAKAN FUZZY PADA PERUSAHAAN PUBLIK YANG TERDAFTAR DI BURSA EFEK INDONESIA (BEI)
Abstract
Pemilihan Investasi di Bursa Saham menjadi salah satu opsi yang cukup bagus untuk memperoleh keuntungan. Dengan menghitung Pertumbuhan keuntungan dari Rasio Kinerja Perusahaan terdiri dari beberapa 6 Faktor antara lain Debt to Equity Ratio (DER), Return on Asset (ROA), Current Ratio (CR), Return on Equity (ROE), Gross Profit Margin (GPM) dan Total Asset Turnover (TAT). di perusahaan manufaktur. Berdasarkan rasio yang diperoleh dapat digunakan untuk pertimbangan Investasi. Metode Fuzzy yang digunakan untuk melakukan perhitungan adalah Mamdani dengan masing-masing 3 variabel linguistik disetiap Input dan Output. Dalam perhitungan ini sangat membantu kepada calon investor sebagai pertimbangan jika ingin melakukan Investasi. Dengan hasil perhitungan evaluasi dengan menggunakan Mean Absolute Percentage Error (MAPE) sebesar 0,2455.
