Abstrak: In 2007 the government of Baubau gave mining rights permission to the corporation to conduct exploration activities. It was marked by the mayor's decree of Baubau No. 5451/6211/EUD/2007 about empowerment mining exploration rights of PT Bumi Inti Sulawesi (PT BIS) in Sorawolio District. The exploration and exploitation activities of the nickel mine became a trigger of the mining conflict in Baubau. This research used a qualitative approach in which facts were constructed based on the subjects studied by using the critical paradigm and constructivism. These results indicated that the map control of natural resources in Baubau, traditionally (the sultanate era, 1511-1960) for Turakia land; allocated as residential, ome land; allocated for plantation, katampai land; allocated for plantations and forests and kaombo land its use as a forest which was not allowed to be used except for the common good. The mastery of the four land classifications were as common property except katampai land as private property (owned by Wa Ode Wau for the study area). In the Suharto era there was a change (via the legitimacy of positive law) and in the era of regional autonomy changed the allocation of residential space, the garden became mine (mine roads and special terminals), its control changed from private property to private ownership. While the use of a limited production forest in the Soeharto era in part allocated to mine and its governance be private ownership. The actors involved in the use and control of natural resources in the Baubau of the Sultanate, the Central Government, the Government of the province of South East Sulawesi town of Baubau, Governments, Regional House of representatives (DPRD) Of Baubau, apparatus of State security and public order, private parties (PT BIS), society Of Baubau, students and NGOs. Bundle of power occurred which formed an alliance between Government, DPRD Baubau Town and PT BIS, then the Alliance between the community pro mines, mining and PT pro student BUS as well as the Community Alliance counter mine counter mine, students and NGOs. The main cause of occurrence of conflicts of mining in the town of Baubau, namely when the Government town of Baubau give licences (IUP) exploration (formerly mining exploration of the power of permission) to PT buses. The granting of such permission policy controversy about the onset of childbirth RTRW, permit loan limited production forest area usage, environmental permits and building permits. The result of the policy changes the use and control of natural resources in the city of Baubau and environmental pollution. While the form of showdown that occurred as a result of the granting of such permits is the action demonstration and press statement on the stages of the crisis, a conflict that is the destruction of homes and of terror.

Judul: Natural resource conflicts on iron sand mining area: an implication study of regional autonomy (A Case Study in Kulon Progo District Yogyakarta Province)
Abstrak: The social transformation of coastal community in Kulon Progo District, Yogyakarta Province, as a result of ecosystem transformation, has occurred since 1980. These processes take place gradually as the progress of indigenous knowledge and supported by the subsistent local livelihood activities. The local government publishes the mining policy on the coastal area to earn native local income. The impacts of the policy not only triggers the natural resource conflicts between local community; local government; and private sector, but also threaten the sustainability of community’s knowledge evolution; ecosystem; and the local community existence. A qualitative research was conducted to analyzed the natural resource conflicts, power relation, and develop conflicts resolution, used Theory of Decentralization, Theory of Property Rights, Theory of Conflict, and Theory of Human Ecology on the political ecology perspective as conceptual analysis. The concept of Governmentality was used to analyzed the empirical dimensions i.e. : 1) the agrarian structure, 2) the political processes of natural resource policy, 3) the structure of conflict, and 4) the relation of power on natural resource control. The results are that 1) natural resource conflicts are caused by both of material grounds (agrarian structure, decentralization) and immaterial grounds (political economy, partiality), its existence are manifest and latent, 2) the political processes of natural resource policy indicate the involvement of political economy of global economic actor in the context of agrarian changes, 3) the complexity of structure of conflicts are on the level of power, policy, and community, and 4) the power relations of conflicting actors are mutual, conflictual, and neutral. The conclusions are 1) the structure of natural resource conflicts in Kulon Progo District could characterize as multi actors, multi dimensions, multi arenas, and multi matters, manifest and latent, perennial and temporal conflicts, 2) the web of power relations of natural resource in Kulon Progo district are an articulation of agrarian structure, political process of natural resource policy, and the structure of conflicts that occur on decentralized political system, 3) the ecological crisis in Kulon Progo District is connected to social political crisis, and 4) the alternative of natural resource policy in Kulon Progo district is difficult to develop due to the absence of equality, transparency, and trust on the conflicting actors.

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.
