This study aims to determine how significant is the influence of Korean Wave, eWom, and Country of Origin variables on Purchase Intention; Through Brand Image as a Mediation Variable (Study on Purchasing Aloe Vera 92% Shooting Products Nature Republic Gel in the City of Surabaya). The research method used in this study is the questionnaire method, that is, by distributing questionnaires based on the research objectives. The number of respondents taken for the research is 265 respondents. Using the non-probability sampling method with a purposive sampling approach, and the method used in analyzing the data in this study is SmartPLS 2.0. Based on the data analysis, the results show that the Korean wave does not have a significant effect on brand image, but it has a significant positive effect on purchase intention. Country of origin has a significant positive effect on brand image and purchase intention. eWom has no significant positive effect on brand image and purchase intention. Brand image has a significant positive effect on purchase intention. While the mediation results show that brand image is able to mediate the country of origin in the purchase intention of Aloe Vera 92% Nature Republic Gel Shooting, but cannot mediate Korean wave and eWom on purchase intention of Aloe Vera 92% Nature Republic Gel.

Corona Virus Disease (Covid-19) telah menjadi bencana dunia karena menyerang banyak korban di seluruh dunia dan mengakibatkan kematian. Karena virus tersebut menyerang di beberapa negara termasuk Indonesia, pemerintah Indonesia membuat keputusan untuk menutup hotel dan restaurant sebagai pencegahan Covid-19. Pada penelitian ini, metode prediksi akan dilakukan menggunakan Backpropagation dan Adaptive Neuro Fuzzy. Pada prediksi jumlah hotel dan restaurant yang tutup menggunakan Backpropagation dan Adaptive Neuro Fuzzy, dibutuhkan beberapa input seperti jumlah korban di Jakarta, jumlah korban di Indonesia, dan jumlah korban di dunia. Backpropagation dan Adaptive Neuro Fuzzy dapat menghasilkan prediksi jumlah hotel dan restaurant yang tutup mendekati nilai target. Simulasi diterapkan dengan membagi dataset ke dalam data training (80%) dan data testing (20%). Dari simulasi Backpropagation, Backpropagation dapat menghasilkan prediksi jumlah hotel dan restaurant yang tutup pada data training dengan optimal RMSE adalah 9,2422 dan data testing dengan optimal RMSE adalah 8,9419. Dari simulasi Adaptive Neuro Fuzzy, Adaptive Neuro Fuzzy dapat membuat prediksi jumlah hotel dan restaurant yang tutup pada data training dengan optimal RMSE adalah 0,5324 dan testing data dengan optimal RMSE adalah 5,3198.
