Judul: Ekologi Politik Pertambangan di Kota Baubau Provinsi Sulawesi Tenggara
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: Kontestasi aktor dalam perebutan sumberdaya timah di Bangka
Abstrak: This study aims to map the position and role of mining actors (community) in their contestation in a seizure of tin resource in Bangka. In the contestation it is expected that a new direction regarding the transition of consolidation of democracy, that takes place in Bangka, is illustrated or reflected. In an effort to achieve the aim, the contestation of mining actors is confronted with changes in the political ecology of tin resource as well as the determination of the transition of consolidation of democracy towards a better direction or vice versa. This study uses a qualitative approach of Giddens’ structuralism with analysis of the paradigm of Critical Theory. In the historical realism of mining in Bangka, it is illustrated that the state’s dominance through mining corporate (PT Timah Tbk) was very powerful and diminished in the post New Order era. Effort to unravel the things behind that change refers to the work of the Critical Theory paradigm. The research was conducted in the hamlets of Airputih and Mayang in West Bangka Regency with a focus on the contestation of two mining actors with the state, regional government and investor/private actors. The results showed that: (1) the political map of the governance of tin resource in Bangka shifts in character from a state’s monolithic to a distributed multilithic; (2) The non-capitalistic Reformer Actors (RA) carry non-capitalist eco-populist ideology while starting “stop mining” with revitalizing the potential of community modes of production, and Transitional Actors (TA) carry Capitalist ideology while starting “tin for the people” stay afloat with tin mining despite the destruction of the environment; (3) in the practice of mining in Bangka the RA is more accurately described as Rational Actors, while TA is more accurately described as Pragmatic 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.
