Abstract

Program Keluarga Harapan (PKH) adalah program pemberian bantuan sosial bersyarat kepada keluarga miskin dan rentan terdaftar dalam Data Terpadu Kesejahteraan Sosial (DTKS) dan ditetapkan sebagai Keluarga Penerima Manfaat (KPM). Tujuan penelitian ini untuk meramalkan rata-rata jumlah PKM PKH untuk periode 2021. Hal ini dapat dijadikan dasar bagi instansi pemerintah terkait dalam perencanaan kedepannya. Untuk mendapatkan peramalan terbaik digunakan perbandingan dua metode yaitu metode dekomposisi dan metode Exponential Smoothing Holt Winters. Untuk mencapai tujuan penelitian tersebut dilakukan perhitungan kesalahan yang terdiri dari Mean Absolute Percentage Error (MAPE), Mean Absolute Deviation (MAD), dan Mean Square Deviation (MSD). Berdasarkan hasil analisis data, diketahui metode peramalan terbaik untuk meramalkan rata-rata jumlah KPM PKH di provinsi NTB adalah metode Exponential Smoothing Holt Winters. Metode ini dikatakan lebih baik karena memiliki nilai error lebih kecil dibandingkan dengan nilai error metode dekomposisi. Metode Exponential Smoothing Holt Winters menggunakan nilai pemulusan ? = 0,3, ? = 0,1, ??? ? = 0,2 menghasilkan nilai MAPE = 15, MAD = 2761, dan MSD = 1692444.

Abstract

The aim of study is to forecast global tourist visits and compare the forecasting methods to determine the best method using random forest, single exponential smoothing and double exponential smoothing, respectively. These methods are applied in global tourist visit data in West Nusa Tenggara Province. Random forest, single exponential smoothing and double exponential smoothing are familiar methods and are frequently utilized in forecasting. In addition, the three methods have great accuracy for time series data, such as data of global tourist visits. The data used in this study is data of global tourist visits from 2014 to 2021 in West Nusa Tenggara province. Applying the random forest, single exponential smoothing and double exponential smoothing methods in forecasting, the result shows that double exponential smoothing method is the best, based on the smallest value of Mean Absolute Percentage Error (MAPE) of 325.759. The forecasting result found out that tourist visits will increase from previous time, starting from August, 2021 to July, 2021 with an estimated 847 to 1045 lives
