Judul: Relation of The Success level Corporate Social Responsibility (CSR) Programs with Community’s Social Capital. (Case: Corporate social responsibility (CSR) program of PT. ANTAM Tbk, in Malasari Village, Nanggung District, Bogor Regency, West Java)
Abstrak: Program Corporate Social Responsibility (CSR) merupakan suatu komitmen perusahaan untuk menjalankan tanggungjawabnya menjamin berkelanjutan lingkungan sekitar. Saat ini program CSR bukan hanya menjadi suatu beban bagi perusahaan, tapi sebagai investasi sosial yang dapat meningkatkan relasi, kemitraan, produktivitas, public trust, dan lain-lain, salah satunya adalah modal sosial. Penelitian ini bertujuan menganalisis hubungan antara tingkat keberhasilan program CSR ANTAM dengan modal sosial masyarakat. Penelitian berfokus pada program Community Development CSR ANTAM yang di implementasikan di Desa Malasari, Kecamatan Nanggung, Kabupaten Bogor, Jawa Barat. Penelitian menggunakan pendekatan kuantitatif dan didukung oleh data kualitatif dengan menggunakan metode survei. Hasil penelitian menunjukan bahwa tingkat keberhasilan program CSR ANTAM tergolong dalam kategori sedang, karena mayoritas penerima program menilai positif tingkat manfaat dan tingkat keberlanjutan program, serta teridentifikasi pula kekurangan pada tingkat partisipasi. Pada tingkat modal sosial termasuk dalam kategori tinggi, karena mayoritas penerima program mengalami peningkatan pada tingkat kepercayaan, tingkat jaringan dan tingkat norma sosial dengan stakeholders setelah mengikuti program. Hasil uji statistik menunjukkan bahwa terdapat hubungan antara tingkat keberhasilan program CSR dengan modal sosial masyarakat.

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.
