Judul: The Correlation between Community Participation and The Effectiveness of the COVID-19 Vaccination Program (Case: RT 09 dan RT 16 RW 07 Pondok Bambu Village East Jakarta City)
Abstrak: Program vaksinasi COVID-19 sebagai program pemerintah dalam rangka percepatan penanganan pandemi COVID-19 di Indonesia. Partisipasi masyarakat diperlukan dalam pelaksanaan program tersebut. Penelitian ini bertujuan untuk menganalisis tingkat partisipasi masyarakat pada program vaksinasi COVID-19, menganalisis tingkat efektivitas program vaksinasi COVID-19, dan menganalisis hubungan antara tingkat partisipasi masyarakat dengan tingkat efektivitas program. Responden dalam penelitian ini berjumlah 30 orang. Penelitian ini menggunakan metode kuantitatif yang didukung data kualitatif dengan analisis uji korelasi Rank Spearman. Hasil penelitian menunjukkan tingkat partisipasi masyarakat dominan berada pada tingkat informasi, tingkat efektivitas program vaksinasi COVID-19 tergolong efektif, dan tingkat partisipasi masyarakat dengan tingkat efektivitas program vaksinasi COVID-19 memiliki hubungan positif., The COVID-19 vaccination program is a government program in the context of accelerating the handling of the COVID-19 pandemic in Indonesia. Community participation is required in the implementation of the program. This study aims to analyze the level of community participation in the COVID-19 vaccination program, analyze the effectiveness of the COVID-19 vaccination program, and analyze the correlation between the level of community participation and the level of program effectiveness. Respondents in this study amounted to 30 people. This study uses quantitative methods supported by qualitative data with Rank Spearman correlation test analysis. The results showed that the dominant level of community participation was at the information level. The effectiveness of the COVID-19 vaccination program was classified as effective, and the level of community participation and the effectiveness of the COVID-19 vaccination program had a positive relationship.

Judul: The Relationship between Media Literacy Level and Covid-19 Vaccination Participation in Communities in Babakan Village, Bogor City
Abstrak: Partisipasi masyarakat saat ini banyak melibatkan literasi media dalam praktiknya. Ajakan vaksinasi menggunakan dan membutuhkan media sebagai perantara penyampaian berita vaksinasi. Tingginya kasus Covid-19 di Indonesia telah menimbulkan banyak korban jiwa. Tujuan penelitian ini adalah menganalisis tingkat literasi media masyarakat, tingkat partisipasi masyarakat dalam vaksinasi dan hubungan tingkat literasi media dan partisipasi masyarakat. Penelitian ini menggunakan data primer dan sekunder yang diambil dari 50 orang responden dari masyarakat Kelurahan Babakan Bogor menggunakan analisis data Rank Spearman dan Chi-Square. Tingkat literasi media responden secara keseluruhan berada pada kategori sedang. Kemampuan menggunakan adalah yang paling tinggi dibandingkan kemampuan pemahaman kritis dan kemampuan komunikatif. Karakteristik responden media yaitu usia, jenis kelamin, kepemilikan akun media sosial, dan kepemilikan perangkat TIK memiliki hubungan yang signifikan dengan kemampuan menggunakan dan kemampuan komunikatif. Tingkat partisipasi responden secara keseluruhan berada pada kategori sedang. Literasi media pada aspek kemampuan menggunakan dan pemahaman kritis berhubungan secara signifikan dengan tingkat partisipasi masyarakat dalam vaksinasi Covid-19., Community participation currently involves a lot of media literacy in practice. Call for vaccination to use and require the media as an intermediary for conveying vaccination news. The high number of cases of Covid-19 in Indonesia has caused many fatalities. The purpose of this study was to analyze the level of public media literacy, the level of community participation in vaccination and the relationship between the level of media literacy and community participation. This study used primary and secondary data taken from 50 respondents from the Babakan Bogor Village community using Rank Spearman and Chi-Square data analysis. The media literacy level of the respondents as a whole is in the medium category. The ability to use is the highest compared to the ability of critical understanding and communicative ability. The characteristics of media respondents, namely age, gender, ownership of social media accounts, and ownership of ICT devices, have a significant relationship with the ability to use and communicative skills. The level of participation of respondents as a whole is in the medium category. Media literacy in terms of ability to use and critical understanding is significantly related to the level of community participation in the Covid-19 vaccination.

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.
