Judul: The Influence of Experiential Marketing towards Repurchase Intention of Gofood during COVID-19 Pandemic
Abstrak: Coronavirus Disease atau yang dikenal dengan COVID-19 adalah penyakit berbahaya yang dapat menyebabkan pneumonia atau infeksi paru-paru, MERS, dan SARS. Orang berpotensi terpapar COVID-19 melalui kontak langsung, tidak langsung, atau dekat dengan orang yang terinfeksi virus COVID-19. Pemerintah menerapkan kebijakan PSBB dan Gerakan 5M. Pesan antar makanan adalah cara alternatif untuk memesan makanan di masa Pandemi COVID-19. Gofood menjadi salah satu layanan pesan antar terbaik di masa pandemi COVID-19. Penelitian ini secara garis besar bertujuan untuk menganalisis pengaruh experiential marketing terhadap repurchase intention Gofood di Jabodetabek. Responden dalam penelitian ini sebanyak 160 responden. Penelitian dilakukan dengan menggunakan analisis deskriptif dan Structural Equation Modeling (SEM) dengan pendekatan Partial Least Square (PLS). Hasil penelitian menunjukkan bahwa terdapat dua variabel experiential marketing (act experience dan relate experience) yang berpengaruh signifikan terhadap minat beli ulang Gofood selama masa pandemi COVID-19., Coronavirus Disease or known as COVID-19 is a dangerous disease that can cause pneumonia or lung infections, MERS, and SARS. People are potentially exposed to COVID-19 by direct, indirect or close contact with people infected with the COVID-19 virus. The government is implementing a policy of restricting out- of-home activities (PSBB) and 5M movement. Ordering food delivery is an alternative way to order food during the COVID-19 Pandemic. Gofood is one of the top delivery service during the COVID-19 pandemic. This study broadly aims to analyze the effect of experiential marketing on repurchase intention of Gofood in Jabodetabek. Respondent in this study were 160 respondents. The research is conducted by using descriptive analysis and Structural Equation Modelling (SEM) with Partial Least Square (PLS) approach. The research shows that there are two Experiential Marketing variables (act and relate experience) which significantly influence repurchase intention of Gofood during the COVID-19 pandemic.

Judul: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
