Judul: Tingkat keberhasilan program Corporate Social Responsibility (CSR) Dana Mitra dalam pengembangan masyarakat lingkar tambang
Abstrak: Tujuan penelitian ini adalah untuk mendeskripsikan Program Dana Mitra. Dana Mitra adalah Corporate Social Responsibility (CSR) perekonomian lokal oleh PT Arutmin Indonesia, Tambang Batulicin. Tujuan penelitian ini adalah untuk: 1) mengukur tingkat keberhasilan Dana Implementasi Program Mitra dalam pengembangan lingkar area tambang, 2) menganalisis hubungan antara karakteristik sosio-ekonomi peserta dengan tingkat keberhasilan Dana Mitra, 3) menganalisis hubungan peran pekerja komunitas dengan tingkat keberhasilan Dana Mitra. Penelitian ini menggunakan pendekatan kuantitatif dengan metode survei. Responden adalah Peserta program Dana Mitra total responden berjumlah 40 orang. Responden adalah dipilih dengan simple random sampling. Pengolahan data kuantitatif menggunakan crosstab, uji korelasi rank spearman dan uji korelasi chi square. Hasilnya, ada Program Dana Mitra tidak berhasil, ada korelasi antar peserta karakteristik sosial ekonomi (tanah dan pekerjaan) dan tingkat keberhasilan Dana Mitra, tetapi tidak demikian halnya dengan karakteristik sosial-ekonomi peserta lainnya (usia, jenis kelamin, status hubungan, pendidikan, pendapatan, etnis) dan ada hubungan antara peran pekerja komunitas dan tingkat keberhasilan Dana Mitra.

Judul: Hubungan Tingkat Penerapan Prinsip Pengembangan Masyarakat dengan Keberhasilan Program CSR PT Pertamina
Abstrak: The Implementation of Corporate Social Responsibility (CSR) is a must for the company as an expression of concern for the social life and environment in addition to pursuit of economic profit. One form of implementation of CSR is the empowerment of local economy. This study aims to analyze the relationship between the principles implementation level of community development with the success of CSR program PT Pertamina. The principles implementation level of community development measured indicators of the program suitability to the participants needs, mentoring programs and participation in local economic development programs. Attainment the principles implementation level of community development indicators are expected relate to the success of CSR programs PT Pertamina that measured from the participation level in KUB, the individual income level in one year, and diversity of income levels program participants. This research conducted in Balongan and Majakerta village, Indramayu using survey methods with 60 respondents. Results showed (1) the principles implementation level of community development is at a medium level; (2) the participation level in KUB is at the level of non-participation (low); the individual income level is at the low and medium income level; diversity of income levels are at a high level; (3) the principles implementation level of community development is positively related to the participation level in KUB; not positively related to the individual income level; not positively related to the diversity of income levels program participants

Judul: Penggunaan Metode Homotopi untuk Menyelesaikan Persamaan KdV (Korteweg-de Vries)
Abstrak: Natural phenomena can be explained using nonlinear mathematical models. In this paper, we studied the solution of KdV equation using the Homotopy method. The KdV equation is used for describing both surface and internal waves. One of the solutions is called a solitary wave. The use of homotopy method to solve the KdV equation required a nonlinear operator which was determined by the nonlinear form of the KdV equation itself. Based on this operator, a recursive formula was obtained to get a sequence of the KdV solution. The higher the sequence order of the sequence used, the closer to the exact solution of the KdV equation.
