Perancangan Media Pembelajaran Multimedia Interaktif Peninggalan Sejarah Indonesia Menggunakan Metode Web Based Learning (Study Kasus : SDS Cerdas Bangsa Namorambe)
Education is one area that has a strong influence on internet technology, especially in teaching and learning activities. Technological development is inseparable from the utilization of Human Resources (HR) in supporting learning and being a solution in a lack of learning media on Indonesian historical heritage material in the SDS Cerdas Bangsa Namorambe Case study, especially in class IV SD students. Therefore the authors conducted research on interactive multimedia learning media. This learning media was made due to the lack of learning media so that the lack of design in learning made students less interested in the teaching and learning process so that it was made using web based learning methods. Web Based Learning (WBL) is a technology-based learning system that is used as the utilization of web technology in learning by delivering access to material through web pages. In developing the system used system analysis use case diagrams and activity diagrams with the type of research using the Research and Development (R & D) method. Keywords:Learning Media, Interactive Multimedia, Web Based Learning

Sistem Penunjang Keputusan Seleksi Calon Karyawan Menggunakan Metode SAW (Simple Additive Weighting) Pada PT. Delta Kristalis
Selection of prospective employees is one of the processes carried out to screen prospective employees to fill the required job vacancies. PT. Delta Kristalis is a company that often selects prospective employees. Based on the current prospective employee selection system, it is less efficient in the screening process for prospective employees. So that the selection and evaluation process for prospective employees can be carried out efficiently at PT. Delta Kristalis, it is necessary to develop a decision support system by implementing the SAW method. The decision support system to be developed is web-based using programming languages.PHP and Mysql as databases so that it becomes a website that can run properly. The criteria used are work experience, last education, age, domicile, and requested salary. The implemented decision support system can present the ranking of the results of the selection so that it can help stakeholders to make decisions on the acceptance of prospective employees
COMPARISON OF HOP DOWNY MILDEW EPIDEMICS USING SPATIAL ANALYSIS
Methods of spatial analysis including distribution fitting, variance-to-mean ratios, Morisita\u27s index, doublet and runs analyses, Greig-Smith analysis and variography were used to investigate the spatial pattern of hop downy mildew. Use of these methods allowed examination of the spatial structure of hop downy mildew at three spatial scales: within hop hills, between nearby hop hills, and for hop hills more separated in space. The results obtained were in general agreement for methods of analysis which assessed spatial structure at the same spatial scale with the exception of Morisita\u27s index of clumping which did not identify clumps of diseased hills of the same size as Greig-Smith analysis and semi-variograms
The use of disjunct eddy sampling methods for the determination of ecosystem level fluxes of trace gases
The concept of disjunct eddy sampling (DES)
for use in measuring ecosystem-level micrometeorological
fluxes is re-examined. The governing equations are discussed
as well as other practical considerations and guidelines concerning
this sampling method as it is applied to either the
disjunct eddy covariance (DEC) or disjunct eddy accumulation
(DEA) techniques. A disjunct eddy sampling system
was constructed that could either be combined with relatively
slow sensors (response time of 2 to 40 s) to measure
fluxes using DEC, or could also be used to accumulate samples
in stable reservoirs for later laboratory analysis (DEA
technique). Both the DEC and DEA modes of this sampler
were tested against conventional eddy covariance (EC) for
fluxes of either CO2 (DEC) or isoprene (DEA). Good agreement
in both modes was observed relative to the EC systems.
However, the uncertainty in a single DEA flux measurement
was considerable (40%) due to both the reduced statistical
sampling and the analytical precision of the concentration
difference measurements. We have also re-investigated
the effects of nonzero mean vertical wind velocity on accumulation
techniques as it relates to our DEA measurements.
Despite the higher uncertainty, disjunct eddy sampling can
provide an alternative technique to eddy covariance for determining
ecosystem-level fluxes for species where fast sensors
do not currently exist

Urban Dispersion Program Overview and MID05 Field Study Summary
The Urban Dispersion Program (UDP) was a 4-year project (2004–2007) funded by the U.S. Department of Homeland Security with additional support from the Defense Threat Reduction Agency. The U.S. Environmental Protection Agency (EPA) also contributed to UDP through funding a human-exposure component of the New York City (NYC) field studies in addition to supporting an EPA scientist in conducting modeling studies of NYC. The primary goal of UDP was to improve the scientific understanding of the flow and diffusion of airborne contaminants through and around the deep street canyons of NYC. The overall UDP project manager and lead scientist was Dr. Jerry Allwine of Pacific Northwest National Laboratory. UDP had several accomplishments that included conducting two tracer and meteorological field studies in Midtown Manhattan
Asian Tracer Experiment and Atmospheric Modeling (TEAM) Project: Draft Field Work Plan for the Asian Long-Range Tracer Experiment
This report provides an experimental plan for a proposed Asian long-range tracer study as part of the international Tracer Experiment and Atmospheric Modeling (TEAM) Project. The TEAM partners are China, Japan, South Korea and the United States. Optimal times of year to conduct the study, meteorological measurements needed, proposed tracer release locations, proposed tracer sampling locations and the proposed durations of tracer releases and subsequent sampling are given. Also given are the activities necessary to prepare for the study and the schedule for completing the preparation activities leading to conducting the actual field operations. This report is intended to provide the TEAM members with the information necessary for planning and conducting the Asian long-range tracer study. The experimental plan is proposed, at this time, to describe the efforts necessary to conduct the Asian long-range tracer study, and the plan will undoubtedly be revised and refined as the planning goes forward over the next year

An Analysis of Wintertime Winds in Washington, D.C.
This report consists of a description of the wintertime climatology of wind speed and wind direction around the National Mall in Washington, D.C. Meteorological data for this study were collected at Ronald Reagan Washington National Airport (Reagan National), Dulles International Airport (Dulles), and a set of surface meteorological stations that are located on a number of building tops around the National Mall. A five-year wintertime climatology of wind speed and wind direction measured at Reagan National and Dulles are presented. A more detailed analysis was completed for the period December 2003 through February 2004 using data gathered from stations located around the National Mall, Reagan National, and Dulles. Key findings of our study include the following: * There are systematic differences between the wind speed and wind direction observed at Reagan National and the wind speed and wind direction measured by building top weather stations located in the National Mall. Although Dulles is located much further from the National Mall than Reagan National, there is better agreement between the wind speed and wind direction measured at Dulles and the weather stations in the National Mall. * When the winds are light (less than 3 ms-1 or 7 mph), there are significant differences in the wind directions reported at the various weather stations within the Mall. * Although the mean characteristics of the wind are similar at the various locations, significant, short-term differences are found when the time series are compared. These differences have important implications for the dispersion of airborne contaminants. In support of wintertime special events in the area of the National Mall, we recommend placing four additional meteorological instruments: three additional surface stations, one on the east bank of the Potomac River, one south of the Reflecting Pool (to better define the flow within the Mall), and a surface station near the Herbert C. Hoover Building; and wind-profiling instrument located along the southern edge of the National Mall to give measurements of the wind speed and direction as a function of height
