Judul: The Influence of Corporate Social Responsibility Program  on Business Development and Welfare of Program Recipients
Abstrak: Program Corporate Social Responsibility merupakan sebuah kewajiban perusahaan yang diatur dalam Undang-Undang Republik Indonesia dengan tujuan menjaga komitmen serta tanggung jawab dalam mewujudkan kesejahteraan dan jauh dari kemiskinan. Tujuan dari penelitian ini adalah untuk menganalisis faktor faktor yang memengaruhi perkembangan usaha yang dilaksanakan dan pengaruh perkembangan usaha terhadap kesejahteraan penerima program CSR. Metode yang digunakan dalam penelitian ini adalah metode kuantitatif dan didukung data kualitatif. Responden penelitian sebanyak 30 orang penerima program CSR PT Freeport Indonesia yang dilaksanakan oleh Yayasan Pemberdayaan Masyarakat Amungme dan Kamoro (YPMAK) sebagai mitra perusahaan dalam melakukan pendampingan dengan menggunakan teknik purposive sampling. Hasil penelitian ini menunjukan dua indikator perkembangan usaha masyarakat penerima program yaitu perubahan tata cara pengelolaan usaha dan luas cakupan usaha mengalami peningkatan dengan dinamika perubahan yang signifikan sebelum dan setelah mengikuti program. Faktor karakteristik individu berpengaruh signifikan dibandingkan peran pendamping terhadap perkembangan usaha, dan perkembangan usaha berpengaruh signifikan terhadap tingkat kesejahteraan penerima program., The Corporate Social Responsibility program is a company obligation regulated in the Law of the Republic of Indonesia with the aim of maintaining commitment and responsibility in realizing prosperity and away from poverty. The purpose of this study is to analyze the factors that influence the development of the business carried out and the effect of business development on the welfare of the recipients of the CSR program. The method used in this study is a quantitative method and is supported by qualitative data. Research respondents were 30 recipients of PT Freeport Indonesia's CSR program carried out by the Amungme and Kamoro Community Empowerment Foundation (YPMAK) as company partners in providing assistance using purposive sampling technique. The results of this study show that there are two indicators of business development of the program recipients, namely changes in business management procedures and the breadth of business coverage has increased with significant dynamics of changes before and after participating in the program. Individual characteristic factors have a significant effect compared to the role of assistants on business development, and business development has a significant effect on the welfare level of program recipients.

Judul: The Relationship of The Success Rate of Corporate Social Responsibility (CSR) Program with Community Independence (Case: Development Program "Halmahera Coffee Cultivation" OF PT Antam Tbk UBPN North Maluku, Baburino Village and Soa Laipoh, Maba Subdistrict, East Halmahera Regency)
Abstrak: Pelaksanaan program Corporate Social Responsibility (CSR) merupakan tanggung jawab korporasi dalam menjalankan bisnisnya. Bergerak dan melakukan kegiatan-kegiatan yang dapat mendorong masyarakat pada wilayah operasional perusahaan agar mendapatkan kesempatan dalam meningkatkan keseimbangan ekonomi dan kesejahteraan melalui program-program yang dilaksanakan. Penelitian ini bertujuan menganalisis hubungan keberhasilan program CSR dengan kemandirian masyarakat yang ditentukan oleh sikap partisipan dalam menanggapi proses pelaksanaan program. Penelitian ini menggunakan metode kuantitatif didukung data kualitatif yang diuji menggunakan SPSS 25.0 For Windows. Hasil penelitian menunjukkan tingkat keberhasilan program CSR dengan kemandirian masyarakat memiliki hubungan dengan kategori sedang, dilihat dari aspek manfaat, kesesuaian, keberlanjutan, dan partisipasi pada variabel keberhasilan program CSR dan kemandirian masyarakat dilihat dari kemandirian material, intelektual, kognitif, manajemen, dan nilai. Hubungan keberhasilan program CSR dengan kemandirian masyarakat berdasarkan hasil uji korelasi Rank Spearman terdapat hubungan yang signifikan antara keberhasilan program CSR dengan kemandirian masyarakat. Kata kunci : Keberhasilan program, CSR, kemandirian, sikap, The implementation of Corporate Social Responsibility (CSR) program is the responsibility of the corporation in carrying out its business. Moving and carrying out activities that can encourage people in the company's operational areas to get opportunities to improve economic balance and welfare through implemented programs. This research aims to analyze the relationship of csr program success with community independence determined by the attitude of participants in responding to the program implementation process. The study used quantitative methods supported by qualitative data tested using SPSS 25.0 For Windows. The results showed the success rate of CSR programs with community independence has a relationship with moderate categories, judging from the aspects of benefits, conformity, sustainability, and participation in the success variables of CSR programs and community independence seen from material, intellectual, cognitive, management, and values. The relationship of csr program success with community independence based on the results of spearman rank correlation test there is a significant relationship between the success of CSR programs and community independence.

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.
