Judul: Corporate Social Responsibility Contribution Program to Community Income and Employment Opportunities in Klapanunggal District, Bogor Regency (Case Study: CSR Program of PT Indocement Tunggal Prakarsa Tbk in Quarry D Area, Klapanunggal District, Bogor Regency, West Java)
Abstrak: Keberadaan PT Indocement Tunggal Prakarsa Tbk memberikan dampak negatif terhadap lingkungan dan sosial ekonomi masyarakat sekitar akibat aktivitas penambangan di Desa Lulut. Kondisi sosial ekonomi masyarakat Desa Lulut seperti pengangguran atau bekerja serabutan sehingga dari sisi pendapatan rendah. Perusahaan ini berkewajiban melaksanakan tanggung jawab sosial bagi masyarakat sekitar yang terdampak. Salah satu program CSR yang dilaksanakan adalah Kelompok Tani Sauyunan (Poktan Sauyunan) yang merupakan salah satu program CSR khusus yaitu Sustainable Development Program. Tujuan penelitian ini adalah: (1) Menganalisis kontribusi program CSR terhadap pendapatan anggota Poktan Sauyunan, (2) Menganalisis kontribusi program CSR terhadap kesempatan kerja masyarakat Desa Lulut. Kontribusi program CSR terhadap pendapatan anggota Poktan Sauyunan dianalisis menggunakan uji beda Wilcoxon, analisis pendapatan usahatani dan R/C ratio. Kontribusi program CSR terhadap kesempatan kerja masyarakat dianalisis menggunakan analisis deskriptif. Hasil penelitian menunjukkan bahwa pendapatan masyarakat terjadi peningkatan yang signifikan setelah mengikuti program CSR dengan kontribusi sebesar 84% dari pendapatan total kepala keluarga anggota poktan. Kontribusi terhadap kesempatan kerja masyarakat Desa Lulut yaitu menciptakan masyarakat produktif dengan penyerapan total HOK dari anggota poktan sebesar 885 HOK per tahun atau sebesar Rp 50.445.000. Selain itu, anggota poktan memiliki penghasilan tetap tiap bulan dibandingan sebelum bergabung dengan Poktan Sauyunan., The existence of PT Indocement Tunggal Prakarsa Tbk has a negative impact on the environment and the socio-economic environment of the surrounding community due to mining activities in Lulut Village. The socio economic conditions of the Lulut Village community such as unemployment or odd jobs so that in terms of low income. This company is obliged to carry out social responsibility for the affected surrounding communities. One of the CSR programs implemented is the Sauyunan Farmer Group (Poktan Sauyunan) which is one of the special CSR programs, namely the Sustainable Development Program. The aims of this study are: (1) to analyze the contribution of the CSR program to the income of Poktan Sauyunan members, (2) to analyze the contribution of the CSR program to the employment opportunities of the Lulut Village community. The contribution of the CSR program to the income of Poktan Sauyunan members was analyzed using the Wilcoxon difference test, farm income analysis, and R/C ratio. The contribution of CSR programs to community employment opportunities was analyzed using descriptive analysis. The results showed that the community's income had a significant increase after participating in the CSR program with a contribution of 84% of the total income of the family heads of poktan members. Contribution to the employment opportunities of the Lulut Village community is to create a productive society with a total absorption of HOK from Poktan members of 885 HOK per year or Rp 50.445.000. In addition, Poktan members have a steady income every month compared to before joining the Poktan Sauyunan.

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.
