Judul: Consumer Satisfaction Analysis for Domba Guling Bang Bens Business
Abstrak: Domba Guling Bang Bens menjalankan bisnisnya berdasarkan hasil benchmarking terhadap kompetitor untuk merumuskan strategi bauran pemasarannya, namun cara ini tidak cukup untuk memenangkan persaingan sehingga diperlukan analisis kepuasan konsumen untuk mendapatkan umpan balik terhadap bauran pemasaran yang diterapkan. Tujuan penelitian ini adalah mengidentifikasi karakteristik konsumen, mengidentifikasi proses pengambilan keputusan pembelian konsumen, menganalisis kepuasan konsumen, dan menyusun rekomendasi perbaikan kinerja. Metode menggunakan analisis deskriptif, Customer Satisfaction Index (CSI) dan Importance Performance Analysis (IPA). Karakteristik konsumen Domba Guling Bang Bens berusia diatas 41 tahun, berjenis kelamin laki-laki, dan bekerja sebagai pegawai swasta. Mayoritas membeli untuk kebutuhan konsumsi acara, mendapatkan informasi dari iklan dan promo di media sosial serta pertimbangan membeli karena iklan dan promosi yang menarik. Hasil analisis CSI nilai sebesar 84,56% dan hasil pemetaan menujukkan terdapat dua atribut menjadi prioritas utama untuk perbaikan, yaitu kecepatan dan kesigapan pelayanan serta kenyamanan dan kebersihan lokasi. Rekomendasi yang diberikan adalah memanfaatkan platform integrasi chat, membuat SOP kebersihan, dan pertimbangan pemisahan lokasi atau memberikan sekat pemisah., Domba Guling Bang Bens bases its business strategy on benchmarking against competitors to formulate its marketing mix. However, this approach alone is insufficient to win the competition. Therefore, a consumer satisfaction analysis is necessary to gather feedback on the implemented marketing mix. The objectives of this study are to identify consumer characteristics, understand the consumer purchasing decision process, analyze consumer satisfaction, and develop performance improvement recommendations. The methods used include descriptive analysis, Customer Satisfaction Index (CSI), and Importance Performance Analysis (IPA). The characteristics of Domba Guling Bang Bens’ consumers are predominantly male, over 41 years old, and employed in the private sector. Most purchases are for event consumption, with information obtained from advertisements and promotions on social media, and purchase decisions influenced by attractive ads and promotions. The CSI analysis shows a satisfaction rating of 84.56%, and the mapping results highlight two main attributes for improvement: service speed and responsiveness, and the comfort and cleanliness of the location. The recommendations include implementing chat integration platform, establishing a cleanliness SOP, and considering location separation or partitions.

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.
