Android-based Mobile Multimedia Application Development Training

<p align="center">Covid-19 demands the use of technology as an online learning media tool. The technology that becomes a low-cost developer is the Android Technology operating system. The main target of this community service activity is the 3rd &amp; 5th semester Computer System Study Program students at the Faculty of Science and Technology at the Panca Budi Development University in using Android technology, where learning about Android has been carried out but not maximized in building a Mobile Application. The method used is to provide training and demonstrations in making Multimedia Applications using Android Studio with online media support in the form of Zoom, YouTube, and Google Drive links. The results of the feedback response to material questions submitted by the resource person were 67% very good, participant responses to the material presented were 41% good, the relationship between material and participant needs was 59% very good, the relationship between material and applications that could be absorbed by participants was 54% very good, the linkage of the material with needs is 42% good, the presentation technique of the presenter is 56% very good, the time spent by the presenter is 44% giving a good response, the clarity of the material is 59% clear, the interest of the participants is 47% good, and overall satisfaction level of 51% gave a satisfied response to the training activities.</p>

Mobile Multimedia Evaluation: Development of Stop Drugs Tutorial

This research is intended to evaluate the development of mobile multimedia based stop drug tutorial. This tutorial as a campaign to stop drugs, that should encourage people’s ability to integrate all information on mobile application. The tutorial focuses on how people understand about drugs and what to do if someone is drugs addicted. Stopping drug tutorial is created using ADDIE instructional development method, and during the developing stage, it is done using Multimedia Development Life Cycle according to Luther. Subjects of the research are experts in education, visual communication and information technology in the preliminary testing. Evaluation was conducted using the analytic descriptive method on mobile multimedia evaluation method, and interpreted in a narrative way based on the research findings. The evaluation of mobile multimedia application uses combination of multimedia evaluation that is used by educationalist with ISO 9126 that was used by software developer. The research findings show that mobile multimedia stop drugs application can be used with minor revision.

Efficient Scratchpad Memory Management for Mobile Multimedia Application

Mobile devices have been popular in recent years and the proliferation of mobile devices inspires the interest in mobile multimedia applications. However, memory is always the bottleneck in the traditional memory hierarchy. Scratchpad memory (SPM) is a promising on-chip SRAM to solve such problem. It has faster access time and less power-consumption compared to cache and off-chip memory. In this paper, we propose the efficient scratchpad memory management approach for mobile multimedia applications. SPM is partitioned for the assignment of the slices of the applications based on the profiling and the recorded history. Through the use of SPM, the memory footprint of mobile multimedia applications will be reduced for better performance and less power-consumption. The experimental results show that our approach is able to significantly reduce the power consumption and improve the performance of mobile multimedia applications.
