Mobile Learning: Utilization of Media to Increase Student Learning Outcomes
Get PDFThe low learning outcomes of students from year to year in the department of informatics in the course of data structure affect the learning outcomes. The purpose of this research is to know the difference between Student Learning Result between Using Mobile Media Learning application with Conventional Learning. Using a Quasi-Experimental Design. The sampling technique used is Cluster Purposive Sampling. Samples were divided into two groups: experimental groups taught using media mobile learning apps, and control groups taught using conventional learning. The test result data were tested using the Shapiro-Wilk test to know the data normality, F test for data homogeneity, and t-test to know the difference of learning result value with significant level (α = 0.05). Based on the data analysis result, a normality test result with the Shapiro-Wilk test obtained the value of both groups of samples is the normal distribution and the result of the F test is homogeneous. T-test result obtained by probability = 1.830 with α = 0.05 so probability value <α = 0.05 which means H0 is rejected, hence there is the difference of result of student learning between using application of Mobile learning media with conventional learnin
Study of the Android and ANN-based Upper-arm Mouse
Get PDFDisability is a person's condition in the physical, intellectual, mental, and/or sensory limitations in the long term. This study is reserved for those who do not have the lower arm in order to operate the computer normally. This study uses orientation sensor on the smartphone as the main sensor to move the cursor and click. Delivery of data from smartphone to computer is using Bluetooth. This study will compare two gestures from a combination of orientation sensors on the upper arm: gesture 1 using pitch-yaw motion and gesture 2 using pitch-roll motion; to move the cursor on the monitor. Left-click and right-click using ANN is to detect upper arm jerk movements. Evaluation using ISO/TS 9241-411 standard: ergonomics of human-system interaction; which includes performance evaluation and comfort of the gesture. Performance results of throughput, movement time, comfort and fatigue between gestures were not significantly different between those gestures. The result of the effort questionnaire is that gesture 1 has the highest effort on the shoulder and gesture 2 has the highest effort on the hand
OCT for non-destructive examination of the internal biological structures of mosquito specimen
Get PDFThe Study of mosquitoes and their behavioral analysis are of crucial importance to control the alarmingly increasing mosquito-borne diseases. Conventional imaging techniques use either dissection, exogenous contrast agents. Non-destructive imaging techniques, like x-ray and microcomputed tomography uses ionizing radiations. Hence, a non-destructive and real-time imaging technique which can obtain high resolution images to study the anatomical features of mosquito specimen can greatly aid researchers for mosquito studies. In this study, the three-dimensional imaging capabilities of optical coherence tomography (OCT) for structural analysis of Anopheles sinensis mosquitoes has been demonstrated. The anatomical features of An. sinensis head, thorax, and abdomen regions along with internal morphological structures like foregut, midgut, and hindgut were studied using OCT imaging. Two-dimensional (2D) and three-dimensional (3D) OCT images along with histology images were helpful for the anatomical analysis of the mosquito specimens. From the concurred results and by exhibiting this as an initial study, the applicability of OCT in future entomological researches related to mosquitoes and changes in its anatomical structure is demonstrated
Design of Low Noise Micro Liter Syringe Pump for Quartz Crystal Microbalance Sensor
Get PDFAn injection pump was a critical aspect in the used of Quartz Crystal Microbalance (QCM) biosensor or chemical sensor in liquid. It is required that the pump should have variable speed and doesn't introduce pressure noise to the QCM sensor. In this work, the pump was developed using a micro stepper motor with a microliter syringe. The mechanical transmission transforms the rotational displacement of the motor into a translational displacement of the syringe. The flow rate of the injection pump could affect the signal pattern indicated by a signal spike or instability of the sensor resonance frequency. The developed system successfully minimized the spike signal and improved the stability of the sensor resonance by the used of the microliter syringe pump with optimizing the reaction chamber of the QCM sensor. The flow rate of the pump can be controlled with a minimum speed of 0.7 microliter per second for water. At low flow rate, there was a negligible or none of the spike signal observed during the injection and ejection of the liquid. However, at a high flow rate, few signal spikes may be observed
ML-Optimized Beam-based Radio Coverage Processing in IEEE 802.11 WLAN Networks
Get PDFDynamic Radio Resource Management (RRM) is a major building block of Wireless LAN Controllers (WLC) function in WLAN networks. In a dense and frequently changing WLANs, it maximizes Wireless Devices (WD) opportunity to transmit and guarantees conformance to the design Service Level Agreement (SLA). To achieve this performance, a WLC processes and applies a network-wide optimized radio plan based on data from access points (AP) and upper-layer application services. This coverage processing requires a "realistic" modelization approach of the radio environment and a quick adaptation to frequent changes. In this paper, we build on our Beam-based approach to radio coverage modelization. We propose a new Machine Learning Regression (MLR)-based optimization and compare it to our NURBS-based solution performance, as an alternative. We show that both solutions have very comparable processing times. Nevertheless, our MLR-based solution represents a more significant prediction accuracy enhancement than its alternative
Shortest Route at Dynamic Location with Node Combination-Dijkstra Algorithm
Get PDFOnline transportation has become a basic requirement of the general public in support of all activities to go to work, school or vacation to the sights. Public transportation services compete to provide the best service so that consumers feel comfortable using the services offered, so that all activities are noticed, one of them is the search for the shortest route in picking the buyer or delivering to the destination. Node Combination method can minimize memory usage and this methode is more optimal when compared to A* and Ant Colony in the shortest route search like Dijkstra algorithm, but can't store the history node that has been passed. Therefore, using node combination algorithm is very good in searching the shortest distance is not the shortest route. This paper is structured to modify the node combination algorithm to solve the problem of finding the shortest route at the dynamic location obtained from the transport fleet by displaying the nodes that have the shortest distance and will be implemented in the geographic information system in the form of map to facilitate the use of the system
Fuzzy Logic Controller Design for Leader-Follower Robot Navigation
Get PDFMobile robots are applied everywhere in the human's life, starting from industries to domestics. This phenomenon makes it one of the most studied subjects in electronics engineering. Navigation is always an issue for this kind of robot, to ensure it can finish its task safely. Giving it a “brain” is one of the ways to create an autonomous navigating robot. The Fuzzy logic controller is a good choice for the “brain” since it does not need accurate mathematical modeling of the system. Only by utilizing the inputs from sensors are enough to design an effective controller. This paper presents an FLC design for leader-follower robot. This FLC design is the improvement of FLC application in a single two differential-driven mobile robot. The relation between leader and follower robot is modeled linearly as a spring-damper system. Simulation proves the feasibility of the proposed method in several environment setting, and this paper also shows that the method can be easily extended to one leader and more than one follower's formation. The research in this paper has introduced in the classroom as the teaching-learning media to improve students' involvement and interest in robotics and robotics related class. This paper is also part of our campaign and encouragement for teachers and students to use low-cost and open source software since not all the universities in developing country can afford the expensive high-end software
Incident and Service Request Management for Academic Information System based on COBIT
Get PDFThis paper explores application of Incident and Service Request Management for academic services. We are using Control Objectives for Information and Related Technologies (COBIT) framework as basis for determining the activities in Incident and Service Request Management. The COBIT itself is an IT governance framework included incident handling and service requests, also providing incident response and service request decisions. The software will be developed as a proof of concept that it brings benefits to academic service operations. For most academic services in university, encountered a problem such as incidents reports or a request for services are not immediately addressed, took a long time to respond, or even lost and left unreadable. It is a good idea to standardize incident management and plant it into academic information systems to enforce its application. In software development, we perform five development stages: requirement analysis, system design, stakeholder confirmation, system development, and system evaluation. In requirement analysis stages, we elicited features from activity describe in COBIT and customize it based on interviews and observation. We design use case diagram, use case scenario and database design in system design stages. In stakeholder confirmation stages, a meeting with the stakeholders held and discuss whether the system complies with the requirements or not. system adaptations are made to answer stakeholders concern. System development is conducted based on confirmed system design. Stakeholder evaluated after they follow the case simulation session. Stakeholders provide an evaluation of the system according to their role, based on their experience when using the system in the simulation session. User experience (UX) aspects are also evaluated based on user's interaction with the system. User experience results obtained meet all aspects, including useful, usable, desirable, findable, accessible, credible, and valuable. The evalu

A MRE was fabricated by mixing silicon rubber, silicon oil and carbonyl iron particles together and then cured for 24 hours in a circular mold. Experimental result shows that that there were decreases in amplitude of the vibration in time and frequency domains when the current applied to the coil is increased
Analysis of Electronic Medical Record Reception using Expanded Technology Acceptance Model
Get PDFInformation technology in the health sector has the potential to increase the quality of patient care by improving process efficiency, reducing errors and reducing costs. But this potential cannot be achieved if there is rejection from stakeholders. In this study, we examine the information technology acceptance model in the medical field. We use Moores's model that was developed from Davis's Technology Acceptance Model by adding the variables that determine the success of information technology acceptance. The variables are divided into two categories: information quality consisting of accuracy, content, timeliness, and format. The Enabling factors consisting technical support and self-efficacy. The case study was conducted among medical personnel at a Hospital in East Java. The subject of research is the use of the electronic medical record. Data were obtained through a questionnaire. Then the data is processed with Partial Least Squares algorithm using PLS software. As a result of the sixteen hypotheses proposed there are fourteen hypotheses accepted and the overall model deemed appropriate
