    One of way of increase quality of education at vocational middle education ladder in this case SMK is with renewal started at school level. Renewal key in this case is renewal speed in so many aspect in level of school. Head Of SMK must be able to create renewal swiftly according to industry world demand growing at full speed causing its (the school can yield graduate appropriate requirement stakeholder. This thing need to be done to pursue lag of progress in the field of industry which has exceeded education world. Writer intentionally adopts theory of relativity from Albert Einstein, that is: E = MC2 telling that every a period (objects) if it is made a change high speed, hence will yield a real large energy. In the formula speed becomes main key, that is velocity of light (3 x 108 per second) and the speed still be square so that speed required to become (9 x 1016 per second). The Concept in the actually theory can be implementation in education world to create renewal especially at SMK. Renewal at SMK needs a real speed height causing yields an actual model of which can be applied in solving vocational educational problems. Renewal model of SMK has characteristic as follows: speed in creating change and decision making together, accountability, transparency, innovation, creativity, vision and mission school, pays attention to requirement of member of school ( teacher, student, committee, and public around school), pays attention to requirement IT ( information technology), and relevancy with requirement stakeholder ( industrial world). Renewal model for expansion of SMK covers three main processes, that is a) ability of headmaster to create change and decision making with solve problem with speed which height based on by requirement stakeholder, b) The headmaster role in accountability, transparency, creation of innovation, and creativity, c) The renewal process of SMK must be adapted for religion values and Indonesian culture

    There are three levels in producing oil or natural gas: primary recovery where oil flows into the wellbore by itself; secondary recovery where oil flows with the help of water or gas injection; and tertiary recovery, commonly called Enhance Oil Recovery (EOR). Total recovery from one oil field is about 50% -60% of OOIP. With primary and secondary recovery 30% -40% can be obtained from OOIP, it is expected that the remaining 20% -30% can be taken with EOR. This study investigated EOR by injection of various surfactant concentrations at temperatures of 30°C and 80°C using brine with salinity of 10,000 ppm by imbibition. The aim of this research is to know the effect of surfactant concentration and salinity of the formation water on oil acquisition in relation to sandstone permeability, and to find out what level of concentration to the average permeability rate with temperature close to reservoir average temperature (80°C), can be obtained a minimal Sor so that RF (Recovery Factor) to be maximal. The methodology used is to measure: the physical properties of rocks and fluids (the solution used), the interface voltage and selected the best solution (the smallest interface voltage), and soaking the rock with Amot test glass. From this study, it can be concluded that the addition of concentration will decrease the density, but the addition of temperature will decrease the density and viscosity; the addition of the surfactant and temperature concentration will decrease the interface voltage until the CMC point is reached; good permeability and porosity may not produce good results when clay contamination is presen

    The growing radical and extreme ideologies recently are not only a concern but also a threat to the social relations of harmony and human peace, including in the border region of Kapuas Hulu, Kalimantan. It is important to spread moderate Islamic teaching to counter this extreme ideology to the people in the border region of Kapuas Hulu. This research examines the roles of religious leaders and religious institutions in disseminating moderate Islam in the border region of Kapuas Hulu to counter the growing influence of radical-extremism. This research employs a qualitative method and the data from field research is presented descriptively. This research shows that religious leaders and religious institutions exist in almost every sub-district in the border region. They teach messages of Islamic moderation that include four principles namely the concept of tawasuth-moderate, tawazun-equality, tasamuh-tolerant, and i`tidal. This principle must be strengthened as a foundation in behaving, acting, speaking, socializing, and living in the Indonesian nation and state. It is on these values and principles that religious leaders and religious institutions reinforce their role in preaching, guiding and fostering people in the border region

    Energy absorption due to the dynamic loads on the moment resisting frame structures often cause damage to elements of the structure. In this study, to minimize the damage that occurs in the moment resisting frame structures, than do the protection of structure such as the addition of additional mass as a external damper expected to give a better response to dynamic load, such as period of vibration shorter, and smaller displacement of structure.In this study conducted experimental studies and analytical portal structure without external damper and the external form of additional mass damper. In the laboratory experiment, the model given impact load. This simulation gives the output in the form of natural frequency, displacement, and the value of the damping ratio of the structure. The results of the study indicate that the external damping in the form of additional mass is not good enough to contribute to the change in natural frequency (fn), but quite effectively provide value changes damping ratio (ξ), the period of vibration (T), and the maximum displacement (δmax) of the structure
