Abstract

The purpose of virtual reality is to enable a motor and cognitive sensor activity ofsomeone in the artificial world created digitally to become imaginary, symbolic orsimulate certain aspects in the real world [1]. This technology is applied to the mediaintroduction of the solar system using the Luther method. The Luther Method consistsof 6 stages, namely Concept, Design, Material Collecting, Assembly, Testing, andDistribution. Luther method has advantages compared to other methods because thereare stages of material collecting which is an important stage in the development ofmultimedia and this Luther method can be done in parallel or can go back to theprevious stage [2]. At the Assembly stage the implementation uses the Unity Engineand Google VR SDK for Unity, the result is a virtual reality application that can displaythe solar system with 3-dimensional objects and an explanation is available on eachobject. While testing the blackbox on a variety of Android devices with differentspecifications. From the results of the application of the Luther method, it is verystructured and can run well in the development of multimedia applications, while theresults of testing, this Android-based virtual reality application cannot run on devicesthat do not have Gyroscope sensors and can run on devices with a minimumspecification of 1GB RAM will but the rendering process on 3D objects is slow.

Abstract

Village community especially Banyuwangi District is still many who have BWT (Bath Wash Toilet) but do not meet the standard. Such as the absence of buildings in accordance with the quality of construction that meet the needs of society. Waste water and bath rooms are disposed of in residential environments. The Government of the Public Works Department has given attention in addressing this issue through the development assistance of BWT. But in selecting the candidate beneficiaries the election process is still done conventionally. The Decision Support System (DSS) was built to help make it easier to determine the prospective beneficiaries of BWT. There are seven eligibility criteria used to assess prospective beneficiaries. Self-Connection House (CH), monthly dues per family, land contributions, population density level per hectare, individual septic tank ownership, shallow well water quality, kitchen waste water disposal and bathrooms. DSS is processed using Simple Additive Weighting (SAW) method calculation. The SAW method is capable of precise assessment. The calculation of the SAW method is based on the criteria value and the specified preference weight. On the system, there are 8 village data used to test the system process. The highest village Data became the beneficiary village of BWT. Based on the overall level of software quality can be concluded that the level of information system quality in the criteria is very good with a percentage of 94%.

Abstract

String matching is an algorithm for matching a text to another text or also known as a text search. There are several algorithms that can be used for string matching, including the Boyer-Moore algorithm and the Brute Force algorithm. The Boyer-Moore algorithm is a string matching algorithm published by Robert S. Boyer and J. Strother Moore in 1977. This algorithm is considered the most efficient algorithm in general applications. The Boyer-Moore algorithm starts matching characters from the pattern on the right. While the Brute Force algorithm is an algorithm that matches a pattern with all text between 0 and n-m to find the existence of a pattern in the text. These two algorithms have different patterns in the search process. In this article, a comparative analysis of the performance of the Boyer-Moore and Brute Force algorithms is carried out in a case study of the search for the Big Indonesian Dictionary (KBBI) based on Android. The search process is carried out by searching based on words and word descriptions. The results of this study indicate that the criteria for running time, the Brute Force algorithm is faster than the Boyer-Moore algorithm with the total running time of the Brute Force algorithm is 168.3 ms in words, 6994.16 ms in word descriptions, while the Boyer-Moore algorithm for running time reached 304.7 ms on the word, 8654.77 ms on the word description. In the testing criteria based on related keywords, the two algorithms can display the same list of related keywords.

Abstract

With the development of advances in computer technology today, most companies and organizations need a decision support system based on information systems, where the information is generally stored in the form of documents / text that is not structured. In this regard, a system for text management that is integrated with the decision support system is needed. One of them is the use of text data classification for anthropometric case studies of several samples. Anthropometry is a measurement of a person's body dimensions. The object of research is gender, first name, and height of a person. The research aims to determine the ratio of the number and height probability level of the number of men and women based on the input into an application using the Naïve Bayes Classifier method. The implementation design uses the Python programming language. The results showed that the height classification data frequency of women was more than the height classification data for men. And the number of height probability of a woman's body is greater than the number of height probability of a man's body.
