Judul: The Analysis of Job Satisfaction’s Dimension towards Organizational Citizenship Behavior at PT Primajasa Perdanaraya
Abstrak: Pandemi COVID-19 ikut memberikan dampak negatif kepada PT Primajasa Perdanarayautama ditandai dengan menurunnya kepuasan kerja dan perilaku Organizational Citizenship Behavior (OCB) karyawan. Pandemi ini juga memaksa karyawan untuk terus meningkatkan kinerja mereka, maka dari itu perusahaan perlu memperhatikan kepuasan kerja dan perilaku OCB karyawan agar kinerja perusahaan meningkat. Penelitian ini bertujuan untuk (1) menganalisis persepsi karyawan terhadap kepuasan kerja dan OCB saat sebelum dan setelah ada COVID-19, (2) menganalisis perbedaan kepuasan kerja dan OCB saat sebelum dan setelah ada COVID-19, (3) menganalisis pengaruh kepuasan kerja dan OCB saat sebelum dan setelah ada COVID-19. Metode penarikan sampel menggunakan nonprobability sampling dengan jumlah responden sebanyak 39 orang . Penelitian ini menggunakan data primer dan sekunder. Metode pengolahan dan analisis data yang digunakan adalah uji wilcoxon dan analisis regresi linear berganda dengan bantuan aplikasi Microsoft Excel dan SPSS. Hasil penelitian menunjukkan bahwa terdapat perbedaan pada dimensi kepuasan kerja dan OCB saat sebelum dan setelah ada COVID-19. Selain itu, baik saat sebelum dan setelah ada COVID-19 dimensi kepuasan kerja secara simultan berpengaruh terhadap OCB, namun secara parsial saat sebelum ada COVID-19 variabel yang memberikan pengaruh positif dan signifikan adalah pekerjaan itu sendiri (X1), kompensasi (X2), promosi (X3), rekan kerja (X5), dan kondisi kerja (X6). Sedangkan pada saat setelah ada COVID-19, variabel yang memberikan pengaruh positif dan signifikan adalah kompensasi (X2), dan kondisi kerja (X6)., The COVID-19 pandemic also had an impact on PT Primajasa Perdanarayautama, marked by reduced on job satisfaction and employee Organizational Citizenship Behavior (OCB). This pandemic also forces employees to continue to improve their performance, therefore companies need to pay attention to job satisfaction and OCB so that company performance increases. This study aims to (1) analyze employee perceptions of job satisfaction and OCB before and after COVID-19, (2) analyze differences in job satisfaction and OCB before and after COVID-19, (3) analyze the effect of job satisfaction and OCB before and after COVID-19. The sampling method uses nonprobability sampling with 39 total respondents. This study uses primary and secondary data. Data processing and analysis methods used are Wilcoxon test and multiple linear regression analysis with the help of Microsoft Excel and SPSS applications. The results showed that there were differences in the dimensions of job satisfaction and OCB before and after COVID-19. In addition, both before and after COVID-19, the dimensions of job satisfaction simultaneously affected OCB, but partially before there was COVID-19 the variables that had a positive and significant effect were work itself (X1), compensation (X2), promotions (X3), coworkers (X5), and working conditions (X6). Meanwhile, prior to COVID-19, the variables that had a positive and significant effect were compensation (X2) and working conditions (X6).

Judul: Pengaruh Persepsi Dukungan Organisasi dan Resiliensi Karyawan terhadap Kinerja di Masa Pandemi Covid 19 Pada Bank BNI KCU Bogor
Abstrak: Meningkatnya wabah COVID-19 dan pemberlakuan work from home diberbagai perusahaan. Bank merupakan salah satu lembaga yang tetap beroperasi di masa pandemi dan persentase karyawan untuk melakukan WFO ditengah pandemi lebih banyak. Situasi krisis ini tentunya berdampak bagi kondisi psikologi pekerja dan permasalahan organisasi seperti kinerja. Penelitian ini memiliki tujuan untuk mengidentifikasi karakteristik karyawan, menganalisis persepsi karyawan terhadap dukungan organisasi yang dirasakan, ketahanan karyawan dan kinerja serta pengaruh persepsi dukungan organisasi dan ketahanan karyawan terhadap kinerja karyawan. Analisis data menggunakan analisis deskriptif dan SEM-PLS. Karyawan Bank BNI KCU Bogor didominasi oleh karyawan laki-laki, dengan rentang usia 25-40 tahun berjumlah 60 karyawan, sebanyak 30 karyawan di unit marketing, memiliki masa kerja 6-10 tahun serta pengalaman kerja sebanyak 3-4 kali. Karyawan yang menjalani full work from office (wfo) mendominasi. Persepsi karyawan terhadap persepsi dukungan organisasi, resiliensi karyawan dan kinerja menyatakan setuju. Hasil analisis SEM-PLS menunjukkan bahwa persepsi dukungan organisasi serta resiliensi karyawan berpengaruh positif dan signifikan terhadap kinerja karyawan., The increasing outbreak of COVID-19 and the implementation of work from home in various companies. Banks are one of the institutions that continue to operate during the pandemic and the proportion of employees to do WFO in the midst of a pandemic is higher. With this crisis situation, it certainly has an impact on the psychological condition of workers and organizational problems such as performance. This study aims to identify employee characteristics, analyze employee perceptions, perceived organizational support, employee resilience and performance, and the effect of perceived organizational support and employee resilience on employee performance. Data analysis used descriptive analysis and SEM-PLS. The employees of Bank BNI KCU Bogor are dominated by male employees, with an age range of 25-40 years, 60 employees, 30 employees in the marketing unit, 6-10 years of service, and 3-4 times work experience. Employees who undergo full work from office (wfo) dominate. Employees' perceptions of perceived organizational support, employee resilience and performance agree. The results of the SEM-PLS analysis show that the perception of organizational support and employee resilience has a positive and significant effect on employee performance.

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.
