<![CDATA[General knowledge is the knowledge most people know about. LIPI (Indonesian Institute of Sciences) Survey’s in 2015 states 54% of 1,829 respondents are less aware of knowledge and technology information. Most Indonesians prefer using internet for social media rather than seeking information about knowledge or issues in society [1]. This problem can be overcome with more interactive educational media, so can add insight of general knowledge in fun way. Virtual Reality is technology capable of creating interactive virtual environment. Virtual Reality is used to create educational game called LabirinVR. LabirinVR created using GoogleVR SDK with Collision Detection and Stereoscopic Vision Methods. Game interactions utilize Accelerometer and Gyroscope sensors. The application is able to increase the ability of thinking, creativity, and insight of general knowledge of Indonesia and the world. The application function test result is 100% valid and has 98% feasibility level, so it has good UAT (User Acceptence Test) [2], accepted and used by the people.]]>

<![CDATA[Good relationship between company and customers needs to be managed to maintain continuity of the company’s business considering that business competition is very competitive. CV. Tirta Tamanbali is industrial company that manufactures bottled water products located in Bali. Seeing existence of various competitor makes the company’s business processes gradually decline. Examples of decreased business processes experienced by companies that must be closed distributors outside the region. After conducting research, it was found several business processes related to customers that were still not optimally. Some of these business processes are marketing processes that are not carried out by companies, sales processes that have not been integrated where transactions that occur between companies and customers still utilize phones and supporting processes like complaints and questionnaire services that are still done manually and unscheduled. Based on these problems, the development of business processes starting from modeling stage to implementation is carried out by utilizing the E-CRM application VTiger CRM. Results of this research are in the form of new business process modeling, implementation using VTiger CRM, and recapitulation of technology acceptance questionnaires from company employees. Speciafically for the questionnaire, an additional module was developed because the module was not available in VTiger CRM.]]>

<![CDATA[Communication via sockets is used to transmit information between applications or between processes over network or locally. ZeroMQ is a library for sending messages using sockets that are quite well known. Talking about sending data, message security is an important part that needs to be taken into account, especially when sending data over a network. ZeroMQ sends messages openly without securing the messages sent. This is evidenced by research which states that ZeroMQ does not have a security layer for sending messages over the network and direct observation of message packets using the wireshark application. Therefore, this study creates a method of securing and authenticating message delivery using AES (Advanced Encryption Standard) CBC (Cipher Block Chaining) mode combined with an authentication method. The AES CBC mode was chosen because it is faster than other methods and has strong encryption. This encryption and authentication are used so that the sender and recipient of the message are both valid senders and recipients so that no message changes during message delivery and messages can only be opened by the message recipient and the sender of the message. Tests are conducted to measure the effect of encryption and authentication on message delivery performance. Based on the tests conducted, there is an increase of 7% from normal delivery speed and the potential for messages is not up to 0.3% - 1.5%.]]>

<![CDATA[Dengue disease has been known to the people of Indonesia since 1779. The Aedes mosquito has two types, namely Aedes aegypti and Aedes albopictus. Aedes aegypti is a mosquito that carries the dengue virus. The dengue fever cases in Bali province tend to increase from year to year, especially when approaching the rainy season. The government's preventive action is needed to tackle the spread of the dengue virus and casualties. Data mining attempts to extract known knowledge or use historical data to find regularity patterns and relationships in a set of data. In this study, data mining predicts the number of dengue cases in Bali's province. The prediction uses several database variables to predict future variables' values, which are not currently known. The process of estimating predictive values based on patterns in a data set. This forecasting aims to assist the government in predicting dengue fever cases in the coming period to prepare appropriate prevention efforts. Forecasting dengue fever cases are carried out using three methods: backpropagation, gaussians, and support-vector machine. The amount of data used was 528 sample data, from 2008 to 2018. The results obtained are that the backpropagation method is better at predicting dengue fever cases with a MAPE error rate of 0.025. Simultaneously, the gaussian method has a MAPE error rate of 0.035, and support-vector machine has a MAPE error rate of 0.060.]]>

<![CDATA[The use of a face as a biometric to identify a person in order to keep the system safe from an unauthorized person has advantages over other biometric characteristics. The face as a biometric has more structure and a wider area than other biometrics, while can be retrieved in a non-invasive manner. We proposed a cloud-based architecture for face identification with deep learning using convolutional neural network. Face identification in this study used a cloud-based engine with four stages, namely face detection with histogram of oriented gradients (HOG), image enhancement, feature extraction using convolutional neural network, and classification using k-nearest neighbor (KNN), SVM, as well as random forest algorithm. This study conducted a classification experiment with cloud-based architecture using three different datasets, namely Faces94, Faces96 and University of Manchester Institute of Science and Technology (UMIST) face dataset. The results from this study are with the proposed cloud-based architecture, the best accuracy is obtained by KNN algorithm with an accuracy of 99% on Faces94 dataset, 99% accuracy on Faces96 dataset, 97% on UMIST face dataset, and performance of the three algorithms decreased in UMIST face dataset with facial variations from various angles from left to right profile.]]>

<![CDATA[Mobile applications that have data transactions between users require a database relational database management system (RDBMS) and RESTful API operating on the hosting service so that all users can access the data. Renting a hosting service is not cheap and creating a RESTful API takes plenty of time. As an alternative to hosting, a free version of the Cloud Firestore service gives full access rights to the database and has an application programming interface (API) to manage data or access data. However, the free version of Cloud Firestore has limitations in terms of storage capacity, read, write, and delete processes. Therefore, redesigning process of the database was carried out into a low-cost version of the database model consisting of SQLite database and a low-cost version of the NoSQL database to overcome this problem. The goal is to reduce storage space usage and read, write, and delete processing on Cloud Firestore. The low-cost version of the database was tested with 6,030 data. The results obtained were savings of 47.27% storage usage, 83.08% write usage, 91.26% read process usage, and 83.19% delete process usage compared to the test results of the relational database model.]]>

AbstractWarga Bali is a local application that is used to make it easier for people to find information about the Balinese calendar. Warga Bali application is also an application that is still in the development process so it must pay attention to the user experience, especially the usability aspect. The usability evaluation in this study was to measure the variables of effectiveness, efficiency and user satisfaction by using 20 research respondents who were selected using simple random sampling from Hindu religious communities domiciled in Bali Province. This study uses the Usability Testing method by combining the Performance Measurement technique to calculate the effectiveness and efficiency variables as well as the Think Aloud technique to evaluate Warga Bali Application interface based on the results of verbalizing input and problems that respondents face when carrying out task scenarios. Data were collected using the given task scenarios and from the suggestions for improvement given by the respondents. Respondents will then fill out the SUS (System Usability Scale) questionnaire which will be used to measure user satisfaction variables. The test results of respondents in the adolescent and adult categories show that the usability level of the effectiveness variable obtained is 96% and 93% which means it is quite high, the efficiency variable has an average of 30 seconds and 38 seconds, the user satisfaction variable from the SUS questionnaire is 46 and 51 which meaning that it is still below the standard SUS score of 68 points. The analysis using the Think Aloud technique resulted in 49 recommendations for improvement from the Warga Bali Application. Further research can carry out further evaluation of the improvement designs that have been made. The results obtained by the researchers can be used as a reference by the Balinese citizen application developers in making improvements from the usability aspect.]]>
