<![CDATA[In the last decades the development of telecommunications technology has increased. In the network access, one of the factors that influences was multipath fading. This study was aimed to simulate the effect of noise on digital communication error detection for various combinations of Eb / No, as well as simulating the effect of various diversity techniques on BER values. In this study the performance of the wireless network communication system was measured in bit error rate (BER) as a function of the ratio of bit energy to noise power. Result of simulation from AWGN channels obtained BER values at Eb / No are 2dB, 4dB, 6dB and 8dB, respectively 4 x 10-2, 1.2 x 10-2, 2.2 x 10-3 and 2 x 10-4. The BER results on fading channels using spatial diversity were better than BER on fading channels without any use of antenna diversity with a difference of 10dB.]]>

<![CDATA[Recently the Indonesian people often get inefficiency of electricity usage. On the other side, in Indonesia, the electricity is mostly produced from steam power plant, which require fuel from non-renewable natural resources. So the highness of demand and the occurrence of inefficiency the electricity usage can increase the consumption of natural resource and the air pollution. Therefore, an early warning system are proposed in this study, become one of the various solution than can increase awareness of the people in efficiency of electricity usage. This system requires the input data of electricity usage in the last 6 months, that will be formed the electricity usage trend from each user using linear regression analysis. Furthermore, this trend will predict the electricity usage for next month, this is used as the limit to give the warning from the system. The outcome from this study is the system that can provide a warning to users if their electricity usage run over the certain limits.]]>

<![CDATA[Conventional presence system have many limitation, in between difficulties in recording data that can have impact on the controlling from lecturer. In the other conventional presence systems are often fraudulent. This research purpose to design and developing electronic presence system in class room that are effective and efficient. In this research we are use biometric fingerprint sensor. There are several stages in this research. The first stage is the needs analysis to explore data and information and then formulate solutions to existing problems. The second stage is system design which includes system architecture design, system workflow design, data flow design, and database design. The third stage is the implementation of the system using programming languages and database software that is applied to microcomputers. The fourth stage is testing the system using black box testing. The last stage of this system development research is evaluation. This research took a case study at the Institut Teknologi Sumatera (ITERA).]]>

<![CDATA[The current industrial development is required to improve the quality of production by continuing to improve the production process in order to continue to compete in the market, both locally, nationally and internationally. This demand also applies to small and medium industries that have limited capital, labor, land and technology. UKM Karya Manunggal is a small business unit that is engaged in making furniture made from bamboo. Problems of SMEs with available land, most areas are used for placement of work in process and placement of materials that should not be used so that it can disrupt the smooth movement of material movement. Mapping the real conditions of Karya Manunggal UKM by using ProModel software can know the description of material handling, input output from each work station and work in process. The closeness relationship between work stations in the initial conditions compared to using Activity Relationship Chart (ARC), resulted in a distance difference of 90.55 meters or changed by 4.94%. The output of a computer simulation results in a change from one process to another that changes. Initial conditions for raw material operators were 99.4% to 59.2%. The operator of the initial condition pattern was 21.9% to 21.2%. The rattan operator had initial conditions of 7.3% to 4.6%. Operators finish initial conditions 2.7% to 2.3%]]>

<![CDATA[Parallel processing is an effective strategy for describing large problems in smaller problems, in which computing techniques use two or more computers to perform a task simultaneously by optimizing the resources of existing computer systems. This study uses parallel processing techniques, in which the object of the search is the process of finding the number of triple vertices not represented in the graph. The parallel worker process then divides the workload into each process and distributes it to other threads in the system to solve a problem. The model used in parallel processing is shared memory. This model optimizes the performance of threads on the processor. The experiments carried out make it possible to conclude that the processing speed of a parallel system is influenced by the number of processes and the number of vertices. On a single computer, the larger the process, the shorter the process. The same with the increase in the number of vertices resulting in a longer time.]]>

<![CDATA[A message/complaint service is a very strategic facility for all stakeholders of an industrial organization. The ergonomic message/ complaint service in the aviation industry is an ergonomics approach based on a standard service system provided by an airline which iseasily accessed/ used and the given response is according to the airline passenger expectations. This research was started by observing the message service/ complaint facilities in the aviation industry (airline) and then the function was analyzed and the improvement to service system facilities was proposed so that it was convenient for the users. The results of the study concluded that there were already message / complaint service facilities in the aviation industry (Airline) but they are not ergonomic and optimal to improve the flight safety, so it is necessary to integrate the message / complaint service system with the safety services to empower the State Safety Program (SSP) according to recommendations of ICAO annex 13, Aircraft accidents and Incident investigations, to improve the flight safety performance.]]>

<![CDATA[Tube bending is a general term for the process of forming metals used to form pipes or tubes permanently. By utilizing plastic deformation, straight objects are bent to form arches. Metal pipes in the form of arches can be used as a connection to machine construction, circular ladders, bicycle frames, motor frames, furniture, musical instruments. To improve time and energy efficiency in the bending process, a roll bending machine is designed. This machine is also expected to meet the needs of buckling pipes so that it can be used as a business field by the community. This machine can bend pipes 3/4 inch to 1 inch with a thickness of 1 mm.]]>

<![CDATA[Lignocellulosic filler such as gmelina wood flour is an alternative of synthetic reinforcements which is ecofriendly, abundant in nature and inexpensive. This research aims to investigate the effects of gmelina wood filler addition on tensile properties, impact strength and morphology of epoxy composites. Filler volume fractions evaluated were10, 20, 30 and 40 percent with 30 mesh filler size. Hand lay-up method was used to manufacture the composites. Tensile strength, tensile modulus, elongation and impact strength were determined based on ASTM standard. Results show that filler addition up to some extents improves the mechanical properties of materials. The optimum tensile properties and impact strength are achieved when 10 percent filler is added into epoxy matrix. Further addition of filler degrades the tensile and impact properties of composites. This phenomenon is due to the existence of weak interfacial interaction between the gmelina wood filler and epoxy matrix for higher filler volume concentration beyond 10 vol. %. The scanning electron micrograph of tensile fracture surface reveals that there are voids, agglomeration and pull-out mechanism which are the cause of the composites failure.]]>
