Proyeksi Indeks Pembangunan Manusia di Purwakarta Tahun 2023-2024
Abstract.This study aims to forecast the Human Development Index (HDI) in Purwakarta Regency for the next two years (2023–2024) using the double exponential smoothing holt method. This method is used because the data shows a linear trend and does not exhibit seasonal patterns. HDI is an indicator of human quality of life, calculated using the geometric mean based on Life Expectancy (LE), Expected Years of Schooling (EYS), Mean Years of Schooling (MYS), and Real Expenditure per Capita. The forecasting of HDI is expected to support strategic decision-making in Purwakarta Regency. Based on the calculation of the human development index in Purwakarta Regency using the double exponential smoothing holt method, the Mean Square Error (MSE) value obtained is 0.067 with parameters α = 0.9 and γ = 0.1, with the forecasting model 71,56 + 0,514m. The forecasted HDI for 2023 is 72.07, which slightly differs from the HDI value calculated by BPS, which is 72.09. Keywords: Human Development Index, Forecasting, Double Exponential Smoothing Holt Abstrak. Penelitian ini bertujuan untuk meramalkan Indeks Pembangunan Manusia (IPM) di Kabupaten Purwakarta selama dua tahun ke depan (2023–2024) menggunakan metode double exponential smoothing holt. Metode tersebut digunakan karena data memiliki tren linear dan tidak ada pola musiman. IPM adalah indikator kualitas hidup manusia yang dihitung menggunakan rata-rata geometrik berdasarkan Umur Harapan Hidup (UHH), Harapan Lama Sekolah (HLS), Rata-rata Lama Sekolah (RLS), dan Pengeluaran Riil per Kapita. Peramalan IPM diharapkan dapat mendukung pengambilan keputusan strategis dalam pembangunan di Kabupaten Purwakarta. Berdasarkan hasil perhitungan indeks pembangunan manusia di Kabupaten Purwakarta menggunakan metode double exponential smoothing holt diperoleh nilai Mean Square Error (MSE) yaitu 0,067 dengan parameter α = 0,9 dan γ = 0,1 dengan model peramalan Ft+m = 71,56 + 0,514m. Hasil peramalan IPM tahun 2023 sebesar 72,07, yang sedikit berbeda dari nilai IPM yang dihitung oleh BPS sebesar 72,09. Kata Kunci: Indeks Pembangunan Manusia, Peramalan, Double Exponential Smoothing Holt
