From various aspects, the role of MSMEs in the national economy involves the government in formulating the Development Program in the National Medium Term Development Plan (RPJMN). The 2004-2009 RPJMN emphasizes a program to develop a business support system for MSMEs and a program for developing entrepreneurship and competitiveness. This concerns the formation of business behavior to achieve a more successful or successful performance and structure of micro, small and medium enterprises.According to Widayatun "Creativity is the ability to solve problems, which gives individuals creating original / adaptive ideas their full usefulness function to develop".Keywords: Creativity; UMKM; RPJMN.

The wear and compatibility characteristics of selected bearing materials, including surface coatings and cemented refractory carbides were investigated in support of a pump development program for advanced Rankine cycle space power plants employing high temperature lithium and NaK. Compatibility of candidate materials with 1100-deg lithium in Cb-1 Zr alloy was studied in tilting capsule tests for durations to 7000 hr. The wear behavior of material combinations was evaluated with a rotating disk-static shoe assembly in lithium and NaK to 1000 deg. The best compatibility and wear characteristics were exhibited by high density molybdenum cemented carbides. Carburized Cb-1 Zr alloy wear resistance was inconsistent but, under the best conditions, was nearly equivalent to that of the cemented carbides. Plasma sprayed coatings of tungsten carbide and WC-Co gave encouraging results in NaK, but additional development of the coating process appeared necessary to assure reliable control of adhesion and performance.

We are developing a practical-scale mechanical decladder that can slit nuclear spent fuel rod-cuts (hulls + pellets) on the order of several tens of kgf of heavy metal/batch to supply UO2 pellets to a voloxidation process. The mechanical decladder is used for separating and recovering nuclear fuel material from the cladding tube by horizontally slitting the cladding tube of a fuel rod. The Korea Atomic Energy Research Institute (KAERI) is improving the performance of the mechanical decladder to increase the recovery rate of pellets from spent fuel rods. However, because actual nuclear spent fuel is dangerously toxic, we need to develop simulated spent fuel rods for continuous experiments with mechanical decladders. We describe procedures to develop both simulated cladding tubes and simulated fuel rod (with physical properties similar to those of spent nuclear fuel). Performance tests were carried out to evaluate the decladding ability of the mechanical decladder using two types of simulated fuel (simulated tube + brass pellets and zircaloy-4 tube + simulated ceramic fuel rod). The simulated tube was developed for analyzing the slitting characteristics of the cross section of the spent fuel cladding tube. Simulated ceramic fuel rod (with mechanical properties similar to the pellets of actual PWR spent fuel) was produced to ensure that the mechanical decladder could slit real PWR spent fuel. We used castable powder pellets that simulate the compressive stress of the real spent UO2 pellet. The production criteria for simulated pellets with compressive stresses similar to those of actual spent fuel were determined, and the castables were inserted into zircaloy-4 tubes and sintered to produce the simulated fuel rod. To investigate the slitting characteristics of the simulated ceramic fuel rod, a verification experiment was performed using a mechanical decladder.

“Leadership is the capacity and the willingness to rally men and women to a common purpose. But it also a character which inspires confidence.” These are the words uttered by Bernard Montgomery, a British Field Marshal, when asked what leadership meant to him. From his quote, he reveals the importance of the role of a leader in any organization. A leader will direct and at the same time emit confidence to his followers. In life, human beings are the main catalyst for the world’s living history. The same applies to any organization. Human is the most important agent that creates, develops and keeps the whole institution running smoothly. However not everyone is capable of leadership. One needs a competent characteristic and various qualifications to execute the role. The organization must first make an effort and sizeable attention to attract such personnel who can make a valuable contribution to the organization. One of the effort may be to establish a leadership development program. With the specific objective of producing more competent leaders, it needs special leader who can guide, influence, and develop people within the organization. Leadership development becomes a serious task for any organization because its fate and future lies on the capability of its new leaders. Leadership development in every organization is both personal and communal. Personal because there is an individual effort to progress and improve himself so that he will finally be trusted to lead in the organization. However this personal progression needs a support system and a structure that supports and facilitate every type of personality to become a dependable leader. This macro support system is communal in characteristic.
