Abstract

Transmetro is a mass public transportation provided by the Pekanbaru city government, under the supervision of the Pekanbaru City Transportation Service. The travel costs offered on public transportation are fairly cheap, and very affordable for the middle to lower class. Each transaction carried out still uses the currency of exchange in the form of fixed currency provided by passengers who wish to travel. Sometimes not all passengers have the exact amount specified in the travel costs. Money back which is sometimes not available requires passengers to give up an amount of money they have. Therefore, this study aims to build a digital wallet application based on an Android device to simplify the transactions to be carried out. Only by filling in a sufficient balance in the application and scanning the QRcode at the time of the transaction, the transaction has been recorded automatically on the Transmetro party database without the need to recap the data.

Abstract

This study aims to build a system that will be used in supervising the guidance of students' final assignments. The final project is one of the courses in the higher education curriculum. However, the Final Project is in a very strategic position in terms of adequate quality of graduates. In the final project, students can show all the knowledge and abilities they have acquired during lectures and academic activities so far [1]. This application also functions as a progressive management, a web-based application because this application can also be used for inventory discussions because this feature is very useful. Not only that, Web-based applications can also work monitoring in the display system. Even the number of Web-Based Applications is now no longer available and can be ordered and tailored to the needs of consumers [2]. This application will be used as an additional menu on the main campus website. This system will later be used by students to input guidance progress. Lecturers use the system as a medium to study the development of each student's guidance. Meanwhile, the administrator has a role to input lecturer data, student data and final assignment title data

Abstract

Case-based reasoning is a methodology for solving problems by utilizing previous experience. In this study the authors apply case-based reasoning to diagnose sexually transmitted infection using the weighted Euclidean distance method. Source of the knowledge base was obtained by collecting medical record of patients with sexually transmitted infections in 2016-2017. The process of finding a solution starts with eliminating irrelevant data using the C4.5 method and continues with the calculation of the similarity value using the Weighted Euclidean Distance algorithm. This system can diagnose 5 types of sexually transmitted infections based on 123 existing symptoms. System result in the form of sexually transmitted infections based on symptoms experienced by the patient, treatment solution and presentation of similarities between new cases and old cases. Based on the result of testing with 127 cases of sexually transmitted infections obtained result: testing uses the K-Fold Cross Validation scenario, the total data is divided into 10fold and the testing process is divided into 2 parts, namely testing using indexing and testing without using indexing. For testing using the highest accuracy indexing obtained at 90.84% in the second fold, and the average accuracy of the entire fold is 88.55% with the average time generated 9498 ms (millisecond), while testing without using the highest accuracy indexing obtained by 63.03% in the second fold, and the average accuracy of the entire fold is 53.48% with the average time generated 9975 ms (millisecond).

Abstract

The weather is one part of human daily life. Many people who depend their lives on the weather to do every activity. Therefore, knowing the weather forecasting will give consideration to the community to be able to carry out various activities of human life such as in the field of aviation, shipping, agriculture, processed industries and others that depend on weather conditions. For this reason, the Indonesian BMKG has the duty to provide weather forecast information based on existing meteorological data using complex calculations. This study aims to build a system that will be an alternative for BMKG in forecasting weather using fuzzy based on four supporting criteria, namely air temperature, humidity, wind speed and air pressure. In doing weather forecasts using mamdani fuzzy there are several steps, namely determining the fuzzy set, the application of the implication function using the MIN function, the composition of the rules using the MAX function, and finally the Defuzzification process using the MOM method. This system will produce weather forecast results based on data on air temperature, air humidity, wind speed and air pressure that have been entered by the system user by showing the membership level of the predicted results. Based on testing that has been done, it is concluded that the system built using mamdani fuzzy can do a good weather forecast with a system accuracy rate of 61,062% using daily weather data as many as 1826 data in 2013-2017, with the lowest accuracy level found in 2015 with an accuracy rate of 54,247 % and highest accuracy in 2017 amounted to 65.207%.

Abstract

The purpose of this study is to find out the influence between the use of the cooperative learning model of the JIGSAW and STAD . This study uses a quantitative method with an experimental approach. The population in this study were students majoring in computer science in the class of language theory and automata, and artificial intelligence. The sampling technique used random sampling techniques. In this study, the research samples were students majoring in computer science. Each class consisted of 33 students selected for the comparative experiment which were two classes. Testing is carried out using a one-way variant (one way Anova). The results of hypothesis testing showed the two data groups had the same variants between the STAD and JIGSAW learning models, with the value of Fcount of 0.5928 and Ftable of 1.79. It was found that Ftable> α, namely 1.79> 0.05, while Fcount> α, namely 0.5928> 0.05. By testing F, for the testing criteria, the value of Fcount < Ftable, (0.5928 <1.79) is obtained, then the accepted hypothesis is H0, meaning that the two data groups have the same variants. So it can be concluded that the application of the STAD and JIGSAW models has an effect on the achievement of student learning outcomes.
