Prayer begins with ablution first to remove najis and hadats. Religion is a rule, guideline, teaching, or system that governs beliefs, beliefs, or beliefs. Islam was revealed by Allah SWT. In Islam, expressing gratitude for every Muslim to the Creator is by praying. Moreover, at this time, the current guidance book on prayer procedures is still running in the delivery of information in the form of text and 2D images. This way is not valuable because it is not mobile style, while currently, human mobility is higher. In this study, we are designing and building a learning application of obligatory prayer based on augmented reality to run on Android-based smartphones and can be studied anywhere and anytime without being limited by space and time. This application contains procedures for ablution and movements of people praying in the form of 3D ani...

Compared to other media such as television, the internet offers relatively lower rates for a longerinstallation period. If it costs 20 million rupiah, an advertiser can only display one ad for one slot for two times.Conversely, for the same fee, advertisers can place weeks of advertisements on the internet. Since online advertisinghas emerged, many digital ad providers have been able to advertise a product. When individuals or their companies(customers) want to advertise products, many of them still don't understand how to use digital advertising providers.The purpose of this study is to provide an information or description in the decision to choose a digital advertisingprovider for car sellers according to customer desires.In this research, a system implemented using the Weight Product (WP) method has a vector V value that is differentfor each custo...

And one of the entertainments is movies. With the increasing number of movies,there are several classifications of movie genres to assist users in finding and selecting movies to watch, but the genreclassification itself is still very general. Due to the above factors, especially in genre, subgenre, rating, movie durationwhich always develops over time according to a certain pattern and also audiences who have different moviepreferences, the researcher sees that there is a need for an application that can recommend movies with preferencesthat can be set according to the wishes of movie lovers. From the problems that arise, this research was built using theSimple Additive Weighting (SAW) method which aims to make it easier for users to determine which movie to choose.This system produces a web-based information system using several ...

Tracking antenna system with auto-tracking capability is the applicable technology which can facilitate the process of channel searching. In a real implementation, the tracking antenna systems need reference parameters which are easily obtained and easily processed on the processors with limited capabilities. The focus of this paper is how to obtain reliable input parameters for the tracking antenna system. Fuzzy Inference system is not used for tracking method but to improve input parameters processing. This paper proposes two possible parameters, among others are the signal indicator and CVBS luminance level. FIS (Fuzzy Inference System) is used as a real-time VQA (Video Quality Assessment) and makes both of parameters as FIS input. The test result shows that both parameters are very feasible to be used as input parameters for tracking antenna system. FIS simulation shows that this algorithm has good performance. This is shown by the simulation results that FIS can adjust the parameter characteristics.

Video quality of analog TV was heavily influenced by performance of the antenna. Most users prefer to use indoor antenna due to its simplicity. The disadvantage of this type of antenna is the users may need to change the antenna direction repeatedly when they change to different TV channel. In this research, we designed and developed tracking system that enable indoor TV antenna to adjust its direction automatically to get optimum video clarity. This system is built by several servo motors and telescopic antennas. Composite Video Baseband Signal (CVBS) processing is used to obtain reference information regarding video clarity level conditions on TV screen. The results show that CVBS signal processing has performance in describing video clarity level. System performance has been verified from trial results on some UHF channels. Minimum tracking time is reach...

This paper proposes VQA system based on FIS (Fuzzy Inference System) that works in real-time to process information from analog signals on AV-Out television. The VQA system can be said to work well if the output results show that the perception of the system is almost close to the perception of the user in assessing the video clarity level. In this research, simulation is performed using MATLAB Toolbox and then implemented by using AVR AT Mega 32 A microcontroller. Result of trial shows that there is no significant difference between simulation and implementation with percentage difference of only 1.74%. Other trial results prove that the perception of VQA system that has been built almost approach the user's perception in assessing the video clarity level. This is evident from the percentage of accuracy on VQA system that reaches 79% to 95%.

Therefore, the authors create a web-based housing geographic information system in Sidoarjo Regency using Breadth First Search to design the system interface and logic, MySQL for database system design and Bing Api for mapping. Information presented in the form of housing names, addresses, photos of housing, pictures of house types, house plans, availability and prices of each type of house. With the GIS (Geographical Information System), it is hoped that the public can more easily and quickly get housing information in Sidoarjo Regency. The results of this study show the details of the housing location from the user's location according to the radius to be selected and know the approximate distance of travel time to the resid...

Mosque Is a place of worship for Muslims worldwide. The city of Surabaya which incidentally is a tourist city that is often visited by foreign and local tourists, and especially the Muslims who want to establish prayer and need access to the location of the nearest mosque. The real condition that often happens is that tourists do not know the position of the closest mosque around them, so spend time searching for the existence of the mosque. Particle Swarm Optimization Method is an algorithm that is inspired by the behavior of a group of birds in a group to look for food. This method is one of the methods for searching the shortest distance. With this method, it can provide solutions to produce the closest location. From the tests carried out, the Particle Swarm Optimization algorithm has been successfully applied to the search for the nearest Mosque location point and has successfully designed and built a nearby Mosq...

Salah satu indikator kegagalan mahasiswa adalah kasus drop out (berhenti studi). Permasalahan drop out menjadi sesuatu yang menarik untuk diteliti, karena hal ini dapat dipengaruhi oleh bermacam faktor. Banyak peneliti yang mengkaji maupun melakukan prediksi drop out berdasarkan faktor internal saja yaitu yang berasal dari dalam diri mahasiswa. Padahal selain faktor tersebut banyak faktor lain yang juga dapat mempengaruhi terjadinya drop out, salah satunya perilaku sosial mahasiswa. Namun tidak mudah menentukan dan mempelajari classifier yang tepat berdasarkan perilaku sosial mahasiswa untuk memprediksi kemungkinan drop out ini. Untuk mengatasi permasalahan di atas, diusulkan model baru untuk mempelajari arsitektur Jaringan Syaraf Tiruan (JST) terbaik, agar menghasilkan classifier yang tepat dalam melakukan prediksi drop out denga...
