Abstract

In recent days, customer care is one of the pivotal aspects in business environment. Quick and reliable response to any of customer question was highly correlated to customer satisfaction and obviously affect the conversion rate of any kind of products or services offered to them. Jogja Sewa Camera is a small company which the main business is to rent a camera. That company serve no less than 25 booking request and questions about the product they offered to the customer. With the limitation of operational staff, the work for responding the customer booking request and question is a bit overwhelmed. Thus, an automated mechanism was built in this research to help the company to handle the customer service. In this research, a chatbot based on Line Messaging Platform was developed for automatic customer service. This chatbot can answer any of frequent or common question and booking request from the customer.

Abstract

Redundancy and robustness are the most common problems in a wireless network distribution system, network system problems that are not able to handle coverage areas in a large / wide coverage, so that the network users are easily disconnected from the connection and out of the server radius. These problems are caused by topology and wireless network distribution methods that are not in accordance with the needs and coverage of its users. However, adding a number of access points en masse to expand the network without being based on appropriate applied methods, is not necessarily able to minimize complaints from network users. Starting from the problems described in the previous paragraph, in this study a wireless distribution mesh system topology (WDS mesh) will be built to improve utility and network usage in the area / radius of the area between access points using wireless lines and minimize cable requirements which are generally the main constraints in network deployment and installation to areas that are difficult to reach. The topology built in this research will implement the wireless routing protocol that results from the analysis and observation process to expand the expansion of service areas to places that are difficult to reach. The wireless routing protocol method used in this study is the Made Mesh Easy (MME) method which is one of the developments of the Interior Gateway Routing Protocol (IGRP) method. Evaluation of the wireless routing protocol in the WDS mesh network topology will be carried out periodically to obtain the results of the analysis that will be used to re-configuring and re-routing to maintain the quality of the network remains realiable. Mesh clients will give feedback on the quality of service obtained based on observations according to IEEE 802.11 standardization. The parameters used are: Througput, Packet Loss Ratio, Latency, Jitter, MOS, Post Dial Delay and Echo Cancelation (EC)

Abstract

Blood pressure is one of the vital sign which widely used as a parameter for medical examination. In some cases likes hypertension, cardiovascular disease or routine examination of pregnant woman, blood pressure test which performed frequently become an important thing. Based on those cases, hence an availability of blood pressure measurement devices will become significant. Thus, in this research, we developed a prototype od digital blood pressure measurement device by using Arduino Uno microcontroller and Android based mobile application. In general, Arduino Uno was equipped with pressure sensorMPX5050DP, those devices will be used for blood pressure measurement. Then the result will be sent and displayed to mobile application. Data transmission between hardware and mobile application was done by using bluetooth module

Abstract

Three-dimensional animation is widely used in various needs, one of its applications can be used as a medium for information on Trans Jogja bus tour line. This information media is useful for Trans Jogja bus users in knowing bus routes so that it is easier to use Jogja Trans buses. In the design of three-dimensional animation, the Trans Jogja bus route uses Paths techniques in the 3D Blender software and in making the application display using Construct 2 software. The design is then implemented in the form of animated videos. The 3D animation application of the Trans Jogja Bus route that is published on the itch.io site gets as many as 115 views and that downloads as many as 127.

Abstract

Creation of 3D object can use a variety of software, one of them using the software Blender. As for the methods in the creation of 3D objects lowpoy and highpoly, among others. Visualization is the process of delivery of information is presented in a 3D visual object so that it looks more interesting and more real, therefore made Building visualization SD Agape Wonosobo which is expected to be utilized by the Foundation for the help the depiction of the building be constructed SD Agape. Creation of 3D objects in this research method using lowpoly. From the results of testing done 3D visualization applications can help visualize building SD Agape will be built, the time you access it based on Browser used most quickly using the Firefox Browser, while based on computers with different time specifications have been influenced from the processor and ram are available the higher faster access time specification, this visualization applications can not be run in an unsupported Browser WebGL.

Abstract

In general, video compression only compresses video files without compressing the audio files in them. This results in the compression process not being maximized.This study discusses the process of compressing video and audio files to get maximum compression. The application built is a web-based video compression software utilizing FFmpeg to do the compression process by breaking down the original video which has a resolution of 720 to 4 files, namely 720, 480, 360, and 240 resolutions. The test is done by comparing the compression results only to video files and compressing to video and audio and there is a 1-2 MB file size difference, whereas when compared to the original file, there is a 5-20 MB size difference. In addition to conducting this test also performed compression testing on different devices and obtained relatively similar results on all devices. Test the image quality on the compressed file obtained the image quality results in the standard video compression below 30dB results.

Abstract

Starts with the development of e-learning with simple technology to social network based on technology such as Edmudo. Because mobile phone users are very large more than two times the internet users, then some experts try to develop a model of learning with mobile phones.The problem is how to give a strong motivation for students to want to use mobile technology in teaching and learning process. This proposed research will create a mobile learning application combined with the control of teaching materials with the aim to increase student enthusiasm to obtain advanced materials after completing the existing material.Outcome to be achieved from this research is the contribution of research in the form of carelearning application with teaching material control method. This study focuses more on the side of instructional media or applications than with the content. Further research involving what form of content appeals to students still needs to be done as a future work of this research.
