CONTROL APPLICATIONS2020-10-07T16:02:08+00:00Yudianto Yudianto Yudiantoyudikalidawir@gmail.com<p class="JMSEAbstractParagraph">Direct numerical control (DNC), also known as distributed numerical control (also DNC), is a common manufacturing term for networking CNC machine tools. On some CNC machine controllers, the available memory is too small to contain the machining program (for example machining complex surfaces), so in this case the program is stored in a separate computer and sent directly to the machine, one block at a time. If the computer is connected to a number of machines it can distribute programs to different machines as required. Usually, the manufacturer of the control provides suitable DNC software. However, if this provision is not possible, some software companies provide DNC applications that fulfill the purpose. DNC networking or DNC communication is always required when CAM programs are to run on some CNC machine control. Wireless DNC is also used in place of hard-wired versions. Controls of this type are very widely used in industries with significant sheet metal fabrication, such as the automotive, appliance, and aerospace industries. A DNC system has to fulfill two basic tasks such as first guaranteeing secure, timely data transfer from and to the CNC controllers, secondly administering many thousands of NC programs.</p>2020-10-07T16:02:08+00:00Copyright (c) 2020 Journal of Mechanical Science and Engineeringhttps://ejournal.unsri.ac.id/index.php/jmse/article/view/11704Development of Interactive Multimedia using Lectora inspire for Vehicle Body Construction Courses in Universitas Sriwijaya2020-10-07T16:02:08+00:00Imam Syofiiimamsyofii@unsri.ac.idDewi Puspita Saridewipuspita@fkip.unsri.ac.idThis study aims to developing interactive multimedia using Lectora inspire for vehicle body construction courses for Universitas Sriwijaya students. The Lectora inspire software was used because easy to operate and can be made interactive electronic learning. Research and development method were used because it is an effective for developing multimedia and able to test the effectiveness of the product. Based on results, the interactive multimedia using Lectora inspire software are valid with percentage of 87.5% for multimedia and 86.9% for matters, practice with percentage in small group test of 85.52% and field test of 86.61%, and effective because based on post-test results 80% of respondents was passed. Thus, interactive multimedia using Lectora inspire software for vehicle body construction courses proper to use in Mechanical Engineering Education study program, Universitas Sriwijaya.2020-10-07T16:02:08+00:00Copyright (c) 2020 Journal of Mechanical Science and Engineeringhttps://ejournal.unsri.ac.id/index.php/jmse/article/view/11705DEVELOPMENT OF INTERACTIVE MULTIMEDIA USING THE MACROMEDIA FLASH AND SCIENCE APPROACH FOR ENGINEERING MATERIALS COURSES IN MECHANICAL ENGINEERING EDUCATION UNIVERSITAS SRIWIJAYA2020-10-07T16:02:08+00:00Imam Syofiiimamsyofii@unsri.ac.idRukiyah Rukiyahrukiyahunsri@gmail.comDewi Puspita Saridewipuspita@fkip.unsri.ac.idThis study aims to developing interactive multimedia using Macromedia Flash and science approach for Engineering Materials courses in study program of Mechanical Engineering Education, Universitas Sriwijaya. The Macromedia flash was used because run easily on a computer or laptop without supporting applications (user friendly). While science approach was used because Engineering Material course are science based. The development of interactive multimedia was used the Rowntree method. The Rowntree method has three stage: planning; development and evaluation. Based on results, interactive multimedia using Macromedia flash and science approach are valid with percentage of 83% for multimedia and 75.58% for matters, practice with percentage in small group test of 86%, and effective with percentage in field test of 100%. Thus, the interactive multimedia that has been developed is recommended for use in study program of Mechanical Engineering Education, Universitas Sriwijaya.2020-10-07T16:02:08+00:00Copyright (c) 2020 Journal of Mechanical Science and Engineeringhttps://ejournal.unsri.ac.id/index.php/jmse/article/view/11392COMPARISON OF CFD SIMULATION WITH 3 TURBULENCE MODELS FOR BREASTSHOT PICO HYDRO TURBINE2020-10-07T16:02:09+00:00Dendy Adantadendyadanta@ft.unsri.ac.idThe breastshot waterwheels are suitable for low head condition because it offers a stable efficiency compared to other types of turbine. In some cases, computational fluid dynamics (CFD) was utilized to predict the performance, geometry optimization or physical phenomena of a breastshot waterwheel, CFD offers easiness in terms of energy, time and cost than doing experimental test. Turbulence modeling is a mathematical method to approach the evolution of turbulence. The aim of this study is to identify the suitable turbulence model for a breatshot waterwheel. These three turbulence models were utilized: k-? standard, k-? scalable near wall function and SST k-?. The braking preloads in simulation was varied, which were 75 N m, 150 Nm, 225 N m and 300 N m. Based on grid convergence index (GCI), the 123k elements of mesh and timestep size of 0.002 s were used and when compared to the exact value, an error below 2% was found. Moreover, the k-? scalable near wall function model and the turbulent SST k-? model give the similar result in torque. Therefore, the simulation test to find torque will be more efficient if using the standard k-? turbulent model because it has computational time which is lower than the turbulent SST k-? model. For the eddy viscosity and turbulence intensity contour k-? standard turbulent model and k-? near wall scalable gives no significant differences, but SST k-? model doe. The simulation test to find eddy viscosity and turbulence intensity contour will be more accurate if using SST k-? model, because this model has the mean rate-of-rotation tensor function, ? , and the blending functions, that makes SST k-? model have better accuracy on the near wall calculation.2020-10-07T16:02:09+00:00Copyright (c) 2020 Journal of Mechanical Science and Engineering
