<![CDATA[The purpose of the study is to analyze land use and land cover change impact on Way Kuripan discharge. Six scenarios of land use and land cover changes at Way Kuripan watershed area of 53.54 km² was developed based on geospatial analysis with Geographic Information System. Peak discharge is calculated by using rational method. From the six scenarios simulation, scenarios 1, 2, 3, and 4 maintained the protected areas of 80.15%. Land use and land cover changes done by changing areas from vacant land and agricultural areas to be residential, industrial and government office areas. From the analysis, peak discharge of scenarios 1, 2, 3, and 4 change slightly which are between 11.19% and 23.46%. These results are in contrast to scenarios 5 and 6, in which scenario 5 keep the protected areas about 53.35% while in scenario 6 left the protected areas around 30%. Those protected areas changed into residential areas. The result showed that in scenario 5, the peak discharge changed about 66.29%. While in scenario 6, it changed about 107.19%. It can be concluded that the existence of protected areas in Way Kuripan Watershed was very important role to reduce the peak discharge values. ]]>

<![CDATA[This document gives formatting instructions for authors preparing papers for publication in the Proceedings of an UBL-ICETD conference. The authors must follow the instructions given in the document for the papers to be published. You can use this document as both an instruction set and as a template into which you can type your own text. The present paper reviews the development of zinc-air battery. Due to its high energy density advantage, the electrochemical system has been extensively studied and developed. However, major problems associated with the electrochemical system remain a formidable challenge, the utmost being to develop an electrically rechargeable zinc-air battery. Efforts made to overcome or mitigate the limitations concerned can be conceptually classified either as solving problems or seeking solutions. The changing paradigm from the electrically rechargeable system to the mechanically rechargeable system is illustrated as an example. Emerging innovations in smart active labels - flat, flexible and functional devices, particularly in healthcare industry, instigated the authors to develop zinc-air battery as a prospective micro-power source for smart active labels. The thin battery technology developed, in collaboration between IIUM and BPPT, is of low cost, comprises of green electroactive materials, and able to operate in quasi-neutral electrolyte. These features fulfil the criteria for the battery to be incorporated into disposable smart active labels.]]>

<![CDATA[Indoor wireless network connectivity is strongly influenced by the presence of interference. Usually transmitted signal can be received in free space or by more than one pathway, because the effects of multipath propagation such as reflection, refraction and scattering of radio waves by the structure of the building, and these effects may be a phenomenon called multipath fading. Multipath Fading is triggered by the presence of loads and very high performance. Propagation model based on user capacity has been identified for possible outcomes, which provide the propagation characteristics as the initial evaluation. Two wireless propagation models, namely empirical and theoretical models related to the coverage, capacity and performance of wireless network users. Empirical and theoretical models used for laying planning system. In addition, this comparison can help to identify the accuracy of the survey measurements when wireless indoor monitoring and it can help to provide an estimate of the coverage and performance of wireless networks in the form of a new topology, along with contour display. Optimization of the planning system laying Wi-Fi user capacity planned by generating an average RSSI reaches -40 dbm to -55 dbm with power 17-18 dbm and canals that channel 1 is applied to 11 non-overlapping in the network design consisting of AP in the adjacent lot. The optimization results are reflected in the new topology along with contour display and spread throughout the area.]]>

<![CDATA[Given edge weighted graph G (all weights are non-negative), The Degree Constrained Minimum Spanning Tree Problem is concerned with finding the minimum weight spanning tree T satisfying specified degree restrictions on the vertices. This problem arises naturally in communication networks where the degree of a vertex represents the number of line interfaces available at a terminal (center). The applications of the Degree Constrained Minimum Spanning Tree problems that may arise in real-life include: the design of telecommunication, transportation, and energy networks. It is also used as a subproblem in the design of networks for computer communication, transportation, sewage and plumbing. Since, apart from some trivial cases, the problem is computationally difficult (NP-complete), a number of heuristics have been proposed. In this paper we will discuss the modification of CW1 Algorithm that already proposed by Wamilia na and Caccetta (2003). The results on540 random table problems will be discussed. ]]>

<![CDATA[inclusion of the name of a university in a ranking system, especially at the top level according to a specific community is important and worth doing. The consideration, including the entry of a university in the list of top universities, is an excellent starting point for the world to recognize the existence of higher education, to boost the image of the university, will also improve promotion, especially in student acquisition and external support. Webometrics is one of the world university ranking system that can be enjoyed by universities in Indonesia. Of the publication in July 2009 a total of 39 universities and the publication in January 2010 as many as 57 universities ranked 6000 Indonesia succeeded in the world. This ranking technique to calculate the accessibility of university websites and publications on google schoolar as the ranking parameter. However, Webometrics do not Rank its based on a study program of higher education. Indonesia has more than 3000 universities which have an operating permit and each university has a study program. Objectivity in the performance of a university can be controlled through the data formulated academic activities through program Evaluation Based Self-Evaluation Study (EPSBED). EPSBED Data published to the public through the website http: \ \ evaluasi.or.id. whereas until now Indonesia has not had a rating system. Case-Based Approach Computing Reasoning (CBR), combined with machine learning algorithms its Nearest Neighbor (NN) as the ranking methodology that uses data EPSBED, then the ranking of a university system may be based on their individual study program.]]>

<![CDATA[This study describes the components of available forage in Vahregan watershed, Central Iran and highlight issues relating to forage endowment and environmental dynamics. In this study, proper use factor and palatability models and their components use to develop the model of available forage and measure it. The components climatic, topography, land systems, vegetation, land use and grass and shrub species composition changes were analyzed using GIS. In this study source of information are herders, land and livestock owners, research institution and personal field inspections. Responses to the questionnaires were obtained from local government offices and research on rangelands and analyzed in parallel with the results of detailed interviews with pastoralists. The results of the completed overall model of available forage showed that of the 18346.2 hectares in the range area only 8.36% of the rangeland is in good condition and the rest are in fair (13.8%), poor and very poor (77.82%). About 16812.85 ha (91.64%) of the rangeland area shows a downward trend, only 1533.35 ha (8.36%) upward trend. About half of the rangeland is not favorable for domestic livestock grazing. The range condition situation and its trend in consideration of soil and slope properties in this study indicates that the rangeland in Vahregan is a fragile production system, sensitive to soil erosion and rangeland degradation, so for a long time sustainable exploitation should be goes to minimize land degradation in the future, proper management and sustainable exploitation should be implemented in the future]]>

<![CDATA[Many ways that is done to separate a mixture such as kerosene-water, such as by using branching pipes (T junction), the construction of the pipeline is composed of one side of the inlet, the run up (straight) and sidearm (upwards). This research aims to determine the effect of superficial velocity of mixture flow pressure difference at the T-junction that occurs on a kerosene-water separation efficiency. Research conducted by using a test section of the T-Junction with a 30 ° slope angle and radius bend 25 mm. pipe Material with a diameter of 1.5 inch Fleksiglass. Media used kerosene and water. The variables measured, namely that of kerosene and discharge water out through the side arm and run arm based on superficial velocity of kerosene and water according the test matrices. The difference in pressure at the T-Junction. Overall results of nicest phase separation occurs at 58% water cut, Jmix = 0.36 m/s downstream flow barriers, with 40% in 550,7 Pa pressure resulted in Fk = Fw = 97% and 2% that flows to the side arm, and Fk = Fw = 3% and 98% of that flows to run arm. The smaller the value of water cut the better efficiency of separation is achieved. The increasing speed of the shear stress of kerosene and superficial result in increasing pressure fluctuations.Also increased pressure downstream barriers. On Jmix 0.36 m/s is highest pressure 1400 Pa, on PSD signal fluctuations of 8000. With the increasing speed of superficial kerosene PSD magnitude decreased, and the strength of the apex of the PSD increased. On a superficial water medium speed with increasing speed of superficial water and kerosene for constant pressure difference loss occurring on the area of the inlet and run T-junction]]>
