Judul: Analisis Manfaat Program CSR (Corporate Social Responsibility) Chevron Geothermal Salak, Ltd Bidang Ekonomi Terhadap Pengembangan Usahatani Padi di Kecamatan Pamijahan Kabupaten Bogo
Abstrak: Industrial process by a company certainly has the side effect of their production then CSR (Corporate Social Responsibility) concept appears. CSR is an action or concept undertaken by the company as a form of their social responsibility or the environtment around them. Chevron Geothermal Salak Ltd (CGS) is one of the companies that administer CSR program. The purpose of the research is to identify the form of the implementation and benefits of economics CSR CGS program of farming and to identify the cost structure and revenue before and after receiving the CSR CGS program and to identify cost structure and the revenue of farmers owner and sharecroppers. The research method is quantitative and qualitative analysis. Quantitative analysis is used with Microsoft Excell 2007. Qualitative analysis illustrated by descriptive. The result shows that the implementation of CSR CGS economics program of farming at Pamijahan consists of several support, those are farming and raising sheep support, Siraa (financial services business partner) cooperation institution support, automotive (machine shop), and woven bamboo and seedlings support. The program that related to rice farming development are farming and sheep support consisting of several activity, such as training and extension in rice farming, seeding and fertilization of organic fertilizer, also sheep assistance. The benefit of CSR CGS program for recepients are providing knowledge and science about rice farming, production result, reduce the cost of production, and independence in the manufacture of fertilizer. Total cost farmers per hectare per cropping season and total cost per kg output of farm before receiving the CSR CGS program is bigger than after receiving the program. The revenue on cash cost and total per hectare per cropping season and per kg output of farm before receiving the CSR CGS is smaller than after receiving the program. Analytical of ratio is also showing that benefit/cost of rice farming before receiving the CSR CGS program is smaller than after receiving program

Judul: Analisis Indeks Kepuasan Masyarakat dan Manfaat Ekonomi Program Corporate Social Responsibility (CSR) Chevron Geothermal Salak, Ltd. Bidang Ekonomi di Kecamatan Pamijahan, Kabupaten Bogor
Abstrak: Aktivitas-aktivitas yang dilakukan oleh perusahaan memiliki berbagai dampak terhadap lingkungan, baik lingkungan internal maupun lingkungan eksternal. Dampak-dampak yang ditimbulkan tersebut mendorong adanya konsep tanggungjawab sosial dan lingkungan atau biasa disebut corporate social responsibility (CSR). Ketentuan hukum positif untuk mengatur regulasi pelaksanaan CSR di Indonesia terdapat dalam Pasal 74 UU Nomor 40. Pasal tersebut berisi tentang kewajiban perseroan terbatas yang menjalankan usahanya di bidang dan/atau berkaitan dengan sumberdaya alam untuk melaksanakan tanggungjawab sosial dan lingkungan. Pemberdayaan masyarakat sangatlah penting dilakukan guna meningkatkan kualitas sumberdaya manusia yang diukur oleh masyarakat dunia dengan IPM (Indeks Pembangunan Manusia) yang saat ini masih di bawah negara-negara ASEAN lainnya. Chevron Geothermal Salak, Ltd. (CGS) salah satu perusahaan yang melakukan kegiatan tanggungjawab sosial (CSR) di wilayah operasinya yaitu di empat desa Kecamatan Pamijahan Kabupaten Bogor. Desa binaan CGS yaitu Desa Ciasihan, Ciasmara, Cibunian, dan Purwabakti yang terdiri dari Kelompok Tani Kacapi, Celempung, Berkah Tani, dan Karya Mandiri, selain itu pendampingan dilakukan pada kelompok pemuda empat desa tersebut dan Koperasi SiRaA. Program-program CSR CGS telah berlangsung sejak tahun 2005 s.d. sekarang dan telah memberikan banyak manfaat bagi masyarakat setempat. Berdasarkan hal tersebut permasalahan yang dikaji dalam penelitian ini yaitu apakah manfaat-manfaat yang dirasakan dari adanya program, berapakah nilai indeks kepuasan masyarakat (IKM) terhadap program, dan bagaimana tingkat kesesuaian antara kinerja pelayanan program dengan harapan masyarakat. Metode analisis dalam penelitian ini adalah analisis kuantitatif yang meliputi penilaian persepsi responden dan informan pada program CSR CGS; perhitungan nilai IKM dan nilai kesesuaian antara kinerja dengan harapan masyarakat. Sedangkan metode kualitatif yang dilakukan meliputi deskripsi dan pembahasan data kuantitatif yang diolah, serta studi literatur mengenai manfaat program, IKM, dan kesesuaiannya. Hasil analisis kualitatif menunjukan bahwa teridentifikasi manfaat-manfaat program CSR CGS yang meliputi, meningkatkan skill, meningkatkan pendapatan, membantu akses permodalan, meningkatkan kemandirian, manfaat yang berkelanjutan. Nilai IKM sebesar 2,75 dikonversi menjadi 68,75, dengan nilai mutu pelayan B dan terkategori Baik. Secara keseluruhan didapat tingkat kesesuaian antara kinerja program dengan harapan masyarakat cukup tinggi yaitu sebesar 78,37 persen yang artinya kepentingan masyarakat sudah terpenuhi dengan baik sebesar 78,37 persen.

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.
