Abstract

Weather is also an important factor in supporting human activities, especially in Indonesia. Human activities that are highly dependent on weather conditions include flight activities, shipping, land travel, agriculture, companies that use the sun as a dryer for their production materials, daily activities (drying cloth). Every day, BMKG Indonesia as an institution engaged in Meteorology, Climatology, Air Quality and Geophysics is tasked with providing information on weather forecasts in Indonesia based on available data. However, at this time it is very difficult to predict the weather conditions because of rapidly changing climate conditions resulting in irregular season changes. Weather conditions are influenced by interrelated elements, namely temperature, humidity, air pressure and the intensity of sunlight. Erratic weather changes can only occur for a few hours and differ in various regions (Puspita, 2016). Fuzzy logic is a level of Boolean logic that deals with the concept of partial truth. Where fuzzy logic maps an input space into an output space by using IF- THEN rules. With the help of the application of Fuzzy logic, this research has the aim of processing the data obtained from temperature, air, and air pressure using Sugeno's fuzzy logic and testing accuracy using MATLAB.

Abstract

Clinics are places or facilities for providing information on drugs and other pharmaceutical supplies to the public. This resulted in uncertain results from sales at the clinic. Types of drugs that are increasingly varied, from drugs that are cheap to prices that if you look at it don't make sense but have very good functions, especially in the distribution of types of drugs. To overcome this problem, the classification of drugs that are sold or not sold at the clinic is based on the variables obtained using the Naive Bayes Agorithm which is able to provide information about the existing products in the clinic and minimize the stock that accumulates for the unsold category. The availability of a lot of data in an area of ​​need for information becomes a reference in making decisions to make business solutions. The desired information in this study is to obtain an accuracy value for the sales data for these drugs, which are often an option. This research uses Rapidminner tools as a medium for testing data to be processed to obtain an ROC (Rank Order Centroid) value of 80% accuracy based on the importance or priority of the criteria.

Abstract

Everyone can now find solutions to their problems either in person or through the internet, which can be accessed via a computer or mobile device, thanks to the advancements in contemporary technology. In addition, this technology is used in various end-use industries, including animal husbandry, agriculture, manufacturing, healthcare, and others. One of the problems that often arises for some people is health problems because it is difficult to obtain information about health, how to maintain health, and how to determine the best actions for handling and prevention, especially considering the needs of the community. for animal health technology services, especially arowana fish. By utilizing the PHP programming language, create an expert system for detecting arowana fish disease on the web. develop an online expert system that can support arowana fish keepers and make consultations more effective. using a forward chaining and defth first search approach. advanced chaining This technique is a way to find information or data that reveals conclusions through facts. In DFS, the leftmost node is where the lookup is performed. The search is carried out on the right node if the previous answer is found at the deepest level. In addition to using the HTML and PHP programming languages, black box testing is used to test the arowana fish expert system website. The design carried out by researchers on this website is limited to problem identification, conceptualization, research objectives, analysis of the necessary data, and the creation of an expert system for diagnosis of web-based arowana fish disease.

Abstract

The alternator is the component of the generator that produces electricity. A short circuit in the alternator causes a surge in electric current so that it can cause an explosion of sparks, it is necessary to prevent an electric short circuit so that maintenance is needed to repair the alternator. Problems in making decisions also occur in companies, in transactions that are used by companies that are still done manually, in determining the price of alternator repairs it is still based on estimates and during the price determination process you have to wait for confirmation from the company's leadership so that the process takes longer and the error rate is relatively high. Fuzzy logic mamdani one method that can be used to overcome this problem. This research will get the best price quickly and minimize the error rate in pricing and adapt it to the implementation design in MATLAB. In the process of determining the repair price, several weighted criteria are required as input variables, namely alternator capacity, level of difficulty and warranty period, which will then produce output variables, namely alternator repair prices. This study aims to assist companies in determining the price of alternator repairs.

Abstract

One of the efforts that can be made to prevent extinction and support the preservation of the Toraja language is to provide a Toraja language dictionary.However, the dictionary was only printed in small quantities so that it could not be accessed by the public at large and there was a decrease in interest in printed versions of dictionaries which were considered already out of date and being replaced by digital dictionaries that are more flexible and practical in their use. In this study using the Rapid Application Development (RAD) method, which is the RAD method, is a method that focuses on developing applications quickly through repeated development and feedback that matches the short target application development time but still adheres to the following stages: stages in making an application. The purpose of this research is to make a Toraja language dictionary application to support the preservation of the Toraja language, prevent the threat of extinction of the Toraja language and introduce Toraja language to the general public outside Tana Toraja. Developments in internet technology and mobile devices make it possible to create dictionaries in web or application form.
