<![CDATA[Searching is a method in the best search to find a solution. The heuristic search method is the most common and most widely used method in the process of finding the shortest path to find a solution. The process of completing searching using the Hill Climbing method, this method uses a heuristic function. The problem in this case is solving the problem of finding the best path to save costs and time in visiting recreational areas in the Batu Sangkar area, Tanah Datar Regency. The advantage of this algorithm is that all possible solutions will be obtained and then checked from the left side one by one, so that a solution with optimal results will be obtained. In its application, the Hill Climbing method uses Geographic Information Systems as a tool in making decisions, by collecting, examining, and analyzing information related to digital maps. with the combination of the Hill Climbing method and geographic information systems can produce an application that can overcome the problem of finding the shortest path.]]>

<![CDATA[Choosing a strategic business location is the dream of entrepreneurs. Site selection can also consider several criteria, namely the bustling market, rental prices, and building area. These criteria become important guidelines in choosing the number of business locations offered. It takes one or several methods used in the decision support system to assist in determining the location of the business. The method used is a combination of AHP (Analytic Hierarchy Process) and SAW (Simple Additive Weighting) which can rank business locations based on predetermined criteria weights. The first step in these methods is the weighting of the criteria based on their level of importance, then proceed with selecting the best alternative by ranking obtained from the results of calculations with both methods. The AHP (Analytic Hierarchy Process) method is used to calculate the weight of each criterion which will be calculated using the normalization matrix of the SAW (Simple Additive Weighting) method. The result of combining these two methods is the best location with the first ranking, namely Poris with a preference value of 0.96. The next ranking is Gondrong, Sipon, Royal, Dadap, Teluk Naga, and the last ranking is Rawa.]]>

<![CDATA[Pupuh Pucung is one part of the sekar alit which is part of the Balinese song. Sekar alit/pupuh has a rule in writing lyrics called padalingsa, which consists of guru wilangan, namely the number of syllables in each line, guru dingdong, which is the vowel in the last word of each line and guru gatra, which is the number of lines in one stanza. This study discusses how the text-to-speech application can help in developing pupuh pucung. Text to speech is an application that converts text into sound. In this research, an application design that can sing Pupuh Pucung's lyrics was developed with the concept of text to sing. This study uses the mbrola application as a text-to-speech converter. The analysis results, namely the frequency of the fundamental tone, aim to determine each phoneme's initial frequency in Pupuh Pucung. With the initial frequency, it will shorten the range of subsequent prosodic observations. The use of pupuh pucung's fundamental tone as a guide for the formation of prosody can be used as an initial guide in forming pupuh pucung's prosody.]]>

<![CDATA[One of the learning processes is to give assignments to students with the aim of increasing students' understanding of the material that has been given, besides that assignments can also be used as an evaluation tool for whether students have understood the material. The obstacle faced by lecturers is the process of checking and recapitulating the value of the assignment, where the value of this assignment will also affect the final score of students. Many lecturers use excel to record the value of this assignment, but this process still takes time, especially if the number of students is quite large. The purpose of this research is to create an application with the help of barcodes to help lecturers facilitate the process of recording assignments, by using this barcode the process of finding student numbers will be very easy and fast. The working principle of this application is, students, include their number on their respective assignment sheets in the form of a barcode, then after the assignment is checked and given a grade, the lecturer scans the student ID using a barcode scanner, the application will look for the student ID and the lecturer just enters value, with this system the process of recapitulating tasks will be fast and accurate]]>
