Abstrak: Indonesia's population growth has increased. This increase was not followed by the addition of the amount of area available on earth. Around 237 641 326 Indonesian people now have to rely on the environment that will animate them. Became one of the industry's growth efforts for the country to be able to improve the welfare of its people. Results from this study showed that the difference Based Wilcoxon test, there were no significant differences in welfare conditions before and after the cement maker, Z = -0.089; p> 0.05, which means that the presence of these companies do not improve the welfare of the community objective. Based on the results of Spearman Rank correlation there is a significant correlation between changes in the agrarian structure and the level of prosperity in the preconstruction period (20 years), r (41) = 0,030; p <0.05, and the correlation between the two was significant (p <0.05). The condition of public welfare changes caused by changes in the agrarian structure which occurred before the company operates so as to encourage changes in the landscape and community involvement.

Judul: Dampak aktivitas pertambangan bahan galian golongan c terhadap kondisi kehidupan masyarakat desa (analisis sosio-ekonomi dan sosio-ekologi masyarakat Desa Cipinang, Kecamatan Rumpin, Kabupaten Bogor, Jawa Barat)
Abstrak: Mining activities is a natural resource mining dredging activities of contained in the soil. This mining activities in its implementation will give positive and negative impact on sosio-economic and sosio-ecological aspect for the local community. The purpose of this study is 1) to explain the sosio-economic impacts of mining activities and 2) to explain the sosio-ecological impacts of mining activities. This research metode uses a quantitative approach supported by the use of qualitative approach. Primary data obtained from the interviews and questionnaires, while secondary data obtained from the documentation and study of literature. The data generated using of cross tabulation and frequency tables and descriptive analysis. The selection of respondents using of cluster sampling techniques to select two different village is Kampung Joglo and Kampung Gunung Cabe. The choice of location is based on mining the large number of industrial plants to see an impact on the agricultural sector. The result of this research showed that in general, in Kampung Joglo and Kampung Gunung Cabe, mining activities gives a negative impacts on socio-economic and sosio-ecological aspects. On sosio-economic aspect are seen in the declining level of the employment in agriculture due to the limited area of agricultural land owned by the local community. Meanwhile, the level of non-agricultural employment opportunities have increased in line with the opening of employment opportunities in the mining sector.

In addition, still many community members who suffers from respiratory tract such as shortness of breath, caugh, colds and diarrhea.

Judul: Penyelesaian Masalah Rotasi Aliran Fluida Kental Von Karman Menggunakan Metode Homotopi
Abstrak: Von Karman equation is an equation that describes fluid viscous flow induced by infinite disk rotation. By assuming steady flow and laminar, viscous incompressible fluid flow is represented in Von Karman equation by an angular velocity and the vertical direction velocity as the independent variables. Von Karman equation is a nonlinear problem that is solved using the homotopy method. The use of homotopy method is done by defining an homotopy function that requires auxiliary parameters to control the convergent region of the solution. The solution is a recursive formula with given initial conditions. Using software based-functional shows that velocity components converge to a value.
