ABSTRAKInvestasi emas merupakan salah satu investasi yang menjadi favorit dimasa pandemi Covid 19 seperti sekarang ini. Hal ini dikarenakan harga emas yang nilainya relatif fluktuatif tetapi menunjukkan tren peningkatan. Investor dituntut pandai dalam berinvestasi emas, mampu memprediksi peluang dimasa yang akan datang. Salah satu model peramalan data deret waktu adalah model Autoregressive Integrated Moving Average (ARIMA). Model ARIMA baik digunakan pada data yang berpola linear tetapi jika digunakan pada data data nonlinear keakuratannya menurun. Untuk mengatasi permasalahan data nonlinear dapat menggunakan model Support Vector Regression (SVR). Pengujian linearitas pada data harga emas menunjukkan adanya pola data linear dan nonlinear sekaligus sehingga digunakan kombinasi ARIMA dan SVR yaitu model hybrid ARIMA-SVR. Hasil peramalan menggunakan model hybrid ARIMA-SVR menunjukkan hasil lebih baik dibanding model ARIMA. Hal ini dibuktikan dengan nilai MAPE model hybrid ARIMA-SVR lebih kecil dibandingkan nilai MAPE model ARIMA. Nilai MAPE model hybrid ARIMA-SVR sebesar 0,355 pada data training dan 4,001 pada data testing, sedangkan nilai MAPE model ARIMA sebesar 0,903 pada data training dan 4,076 pada data testing.ABSTRACTGold investment is one of the favorite investments during the Covid 19 pandemic as it is today.

Crimes forecasting is an important area in the field of criminology. Linear models, such as regression and econometric models, are commonly applied in crime forecasting. However, in real crimes data, it is common that the data consists of both linear and nonlinear components. A single model may not be sufficient to identify all the characteristics of the data. The purpose of this study is to introduce a hybrid model that combines support vector regression (SVR) and autoregressive integrated moving average (ARIMA) to be applied in crime rates forecasting. SVR is very robust with small training data and high-dimensional problem. Meanwhile, ARIMA has the ability to model several types of time series. However, the accuracy of the SVR model depends on values of its parameters, while ARIMA is not robust to be applied to small data sets. Therefore, to overcome this problem, particle swarm optimization is used to estimate the parameters of the SVR and ARIMA models. The proposed hybrid model is used to forecast the property crime rates of the United State based on economic indicators. The experimental results show that the proposed hybrid model is able to produce more accurate forecasting results as compared to the individual models.

Forecasting the tendencies of time series is a challenging task which gives better understanding. The purpose of this paper is to present the hybrid model of support vector regression associated with Autoregressive Integrated Moving Average which is formulated by hybrid methodology. The proposed model is more convenient for practical usage. The tendencies modeling of time series for Thailand’s south insurgency is of interest in this research article. The empirical results using the time series of monthly number of deaths, injuries, and incidents for Thailand’s south insurgency indicate that the proposed hybrid model is an effective way to construct an estimated hybrid model which is better than the classical time series model or support vector regression. The best forecast accuracy is performed by using mean square error.

Berbagai sumber pendapatan yang dapat dihasilkan dalam suatu daerah, salah satunya yaitu dalam sektor pariwisata. Seperti halnya sektor yang lain, sektor pariwisata juga memberikan banyak sumbangan bagi pembangunan ekonomi di suatu daerah maupun negara tujuan wisata. Indonesia memiliki banyak tujuan wisata daerah yang sudah terkenal hingga mancanegara salah satunya yaitu Pulau Bali. Bali merupakan daerah yang sudah memiliki kedudukan yang sejajar dengan daerah-daerah tujuan wisata lainnya yang ada di dunia. Sebagai suatu daerah yang sangat berpotensi dalam pengembangan wisata, maka pemerintah memberikan perhatian yang khusus dalam pengembangan pariwisata di Pulau Bali. Maka dari itu, perlu adanya peramalan jumlah kunjungan wisatawan mancanegara ke Bali yang nantinya bisa bermanfaat bagi pemerintah daerah maupun dinas pariwisata. Dalam hal ini, akan digunakan dua metode untuk meramalkan jumlah kunjungan wisatawan mancanegara ke Bali. Adapun metode yang digunakan yaitu Seasonal ARIMA dan Support Vector Regression (SVR). Hasil peramalan data out sampel dengan menggunakan metode SARIMA dan SVR menunjukkan bahwa metode SARIMA memiliki nilai MAPE lebih kecil dari pada SVR. Nilai MAPE motode SARIMA adalah 5,33% sedangkan metode SVR sebesar 19,74%. Begitu juga nilai MSE dan MAE dari metode SARIMA lebih kecil dari metode SVR.  Dari Penelitian yang dilakukan dapat disimpulkan bahwa model SARIMA merupakan motode yang lebih baik untuk memprediksi jumlah kunjungan wisatawan mancanegara ke Bali.
