Judul: Analisis Persaingan Platform Digital Layanan Pesan-Antar Makanan di Provinsi DKI Jakarta
Abstrak: Industri layanan pesan-antar makanan yakni GoFood, GrabFood, dan Shopee Food saat ini mengalami persaingan yang semakin ketat dampak dari diterapkannya kebijakan PPKM khususnya di Provinsi DKI Jakarta. Hal ini memicu peningkatan penggunaan platform digital dikarenakan tersedianya berbagai alternatif pilihan bagi konsumen, sehingga menuntut perusahaan untuk mampu memberikan keunggulan atribut layanan dibandingkan dengan pesaingnya. Penelitian ini bertujuan mengidentifikasi karakteristik konsumen, mengidentifikasi proses keputusan pembelian, menganalisis tingkat kepentingan dan kepuasan konsumen, dan menganalisis positioning yang terbentuk. Metode penentuan sampelnya yaitu non-probability sampling jenis convenience sampling. Diolah dengan analisis deskriptif, Customer Satisfaction Index (CSI), diagram radar, uji beda one-way ANOVA, Importance Performance Analysis (IPA), dan biplot. Karakteristik pengguna mayoritas adalah pelajar atau mahasiswa. Hasil dari penelitian ini menunjukkan bahwa ketiga perusahaan masih berada pada taraf memuaskan terhadap kualitas layanan yang diberikan sehingga masih perlu perbaikan. Sementara itu, berdasarkan persepsi konsumen, GoFood menekankan pada aspek standar pengemudi yang memperhatikan kerapihan pakaian serta ramah terhadap konsumen, GrabFood pada proses layanan yang menerapkan standar protokol kesehatan yang sesuai, dan Shopee Food sebagai platform digital dengan harga layanan yang terjangkau., The food delivery service industry, namely GoFood, GrabFood, and Shopee Food, is facing fierce competition due to the implementation of PPKM policies, especially in DKI Jakarta Province. The performance has triggered an increase in the use of digital platforms due to the availability of various choices for consumers, thus requiring companies to provide superior service attributes compared to their competitors. This study aims to identify consumer characteristics, the buying decision process, the level of interest and customer satisfaction, and the positioning that formed. The method of determining the sample is non-probability sampling with the type of convenience sampling. Processed by descriptive analysis, Customer Satisfaction Index (CSI), radar diagram, one-way ANOVA difference test, Importance Performance Analysis (IPA), and biplot. The characteristics of majority of users is student. The results of this study indicate that the three companies are still at a satisfactory level for the quality of services, so they still need improvement. Meanwhile, based on consumer perceptions, GoFood emphasizes the formal aspects of drivers such as attention to neatness of clothes and are friendly to consumers, GrabFood on service processes that have health protocol standards, and Shopee Food as a digital platform with affordable service prices.

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.
