Judul: Faktor yang Memengaruhi Intensi Generasi Z Kabupaten Bogor Berinvestasi Pada Green Sukuk
Abstrak: Green Sukuk diterbitkan untuk mendanai pembangunan negara sambil menjaga lingkungan. Generasi Z di Jawa Barat, khususnya Kabupaten Bogor, menunjukkan minat yang tinggi terhadap green Sukuk meskipun tingkat ketidakpedulian lingkungannya tinggi. Penelitian ini menganalisis karakteristik dan pengaruh sikap sosial bertanggung jawab terhadap intensi investasi green Sukuk di kalangan generasi Z Kabupaten Bogor. Metode yang digunakan dalam menganalisis data pada penelitian ini adalah analisis deskriptif dan structural equation modelling-partial least square (SEM-PLS). Dari analisis deskriptif didapatkan mayoritas responden adalah perempuan pada rentang usia 21-24 tahun, berpendidikan akhir SMA, sedang menjadi mahasiswa, berpenghasilan di bawah dua juta rupiah per bulan, dan belum pernah berinvestasi pada green Sukuk. Hasil analisis data dengan metode SEM-PLS menunjukkan bahwa variabel socially responsible consumption terhadap intensi berinvestasi pada green Sukuk dan perception of personal gain terhadap perception of the effectiveness of the action signifikan. Oleh karena itu, pemerintah dan penerbit green Sukuk perlu memperluas informasi terkait green Sukuk., Green Sukuk was issued to fund the country's development while protecting the environment. Generation Z in West Java, especially in Bogor Regency, showed high interest in green Sukuk despite their high level of environmental indifference. This study analyzed the characteristics and influence of socially responsible attitudes on green Sukuk investment intentions among Generation Z in Bogor Regency. The methods used in analyzing data in this study were descriptive analysis and structural equation modeling-partial least square (SEM-PLS). From the descriptive analysis, it was found that the majority of respondents were female in the age range of 21-24 years, had a high school education, were currently students, earned less than two million rupiah per month, and had never invested in green Sukuk. The results of data analysis using the SEM-PLS method showed that the socially responsible consumption variable had a significant effect on the intention to invest in green Sukuk, and the perception of personal gain significantly influenced the perception of the effectiveness of the action. Therefore, the government and green Sukuk issuers needed to expand information related to green Sukuk.

Judul: Factors Influencing Generation Z Muslims in Bogor City in Choosing to Save in Islamic Banks
Abstrak: Perkembangan bank syariah di Indonesia makin baik setiap tahunnya. Jumlah DPK dan pembiayaan di bank syariah mencapai 52,02 juta nasabah, hanya 17,8% dari jumlah penduduk muslim di Indonesia yang merupakan nasabah bank syariah. Hal ini menggambarkan bahwa masyarakat muslim yang menabung di bank syariah masih tergolong kecil. Penelitian ini bertujuan mengidentifikasi dan menganalisis karakteristik serta faktor-faktor yang memengaruhi generasi Z muslim Kota Bogor dalam memilih menabung di bank syariah. Sampel pada penelitian ini sebanyak 120 responden. Metode pengumpulan data dilakukan dengan menyebar kuesioner secara online melalui google form. Pengolahan data menggunakan Microsoft Excel dan SPSS versi 26. Hasil penelitian ini menunjukkan bahwa variabel religiositas, pelayanan, dan reputasi berpengaruh positif dan signifikan terhadap keputusan menabung di bank syariah., The development of Islamic banks in Indonesia is getting better every year. The number of deposits and financing in sharia banks reached 52.02 million customers, only 17.8% of the total Muslim population in Indonesia are sharia bank customers. This illustrates that the Muslim community that saves in sharia banks is still relatively small. This research aims to identify and analyze the characteristics and factors that influence generation Z Muslims in Bogor City in choosing to save at sharia banks. The sample in this study was 120 respondents. The data collection method was carried out by distributing questionnaires online via Google Form.

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.
