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

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

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

Weaning REX rabbits child is one of the keys to success in raising or cultivating rabbits. Unsuitable weaning can result in very high mortality or mortality risks, while weaning for too long results in decreased productivity and the possible marriage of children with rabbit parent. The research done is to design and build the application of decision support system (DSS) with Simple Additive Weighting method (SAW) with 5 criteria as supporting of DSS calculation that are body weight (gram), body length (cm), still breastfeeding or not, already independent for food or not and Gender. The webased DSS application created is tested  by using the calculation system compared with research data. Based on the test of 36 rabbit children which is derived from previous research results obtained showed that the application of the DSS are built 100% the same result.

Abstract

Aviation requires a very high level of security and safety, so that there is no problem that can harm various parties, one of the things that must be considered is about the transportation and handling of Dangerous Goods material. Existing handling system on the flight of dangerous goods systems where outside there is still a lot of risk of handling errors until there is data inaccuracy that can harm various parties, because almost all handling done manually. In addition, the plane does not want to delay and does not want to insert dangerous goods into the plane, so to anticipate the problem conditions, built a system that performs faster, easier and accurate handling, where the system uses PHP programmer language and utilize Telegram API as media Client Server. The built tool explains how to identify packaging, calculations and documents, this tool has reliability with the ability to calculate and identify faster than the manual way with average calculations whose value is significantly different. The values obtained by manually counting which is about 175 Minutes 8 Second or equivalent to 2 Hours 55 Minutes 8 Second and counting with the system  about 94 Minutes 44 Seconds or equivalent to 1 Hour 34 Minutes 44 Seconds, then more than 46% the results are different.

Abstract

The use of the internet, which is currently increasing dramatically, certainly brings the convenience of finding information. The increase in internet usage also eventually gave rise to cybercrime crimes, one of which was by spreading a URL or fake site to steal someone's personal data. The research done is how to build an Android-based application that can detect the security of a URL. The goal is that internet users, especially social media, can avoid cybercrime crime that wants to steal personal data. Making an application uses the Regular Expression method to analyze each line of the Webpage Source Code in the URL based on 8 criteria taken from the World Wide Web Consortium (W3C). The application was then tested with 10 phishing-charged URLs and compared with Kaspersky, McAfee, and AdBlock applications. Based on the results of trials and comparisons, applications that have been made are able to detect 6 or 60% of the 10 URLs. Kaspersky and McAfee applications can detect 70%, while AdBlock only detects 3 or 30% of 10 URLs that contain phishing.
