Abstract

Malang city is a city that has a significant increase in population, which is around 50 thousands people in just period of 5 years. One of the reasons is because Malang city is a city of education, the reasons its called city of education is because in this City there are a lot of public university and private university that are quite popular, such as Universitas Brawijaya (UB), Universitas Islam Malang (Unisma), etc. This resulted many migrants from outside the area of Malang city study in Malang city. There are some things that might be the reasons why migrants choose Malang city, such as the Malang city have one of the best quality university in Indonesia. When becoming a migrant, the most needed thing is certainly a place to live in a long term, because of that the migrants need information on where to live in the form of boarding house or rent house to live in, we can get this kind of information trough social media like Twitter, but on Twitter there is still no category for this kind of information. By seeing this problem, we can use Classification technique to classified the information in the form of living quarters in the city of Malang. In this study Naive Bayes method is used as the classification method, and Information gain as the feature selection method. Before entering the classification process the weighting is done first using TF-IDF-CF method. This study uses 150 training data and 60 testing data. The highest accuracy value in this study are 71,66% using 33% of feature, using TF-IDF-ICF weighthing and, without using number feature.

Abstract

Letter has become a written communication media that is important to fulfill lots of organizations or companies needs. The current thought about organizing letters is that it needs high level of precision which is take too long to be done. This situation is similar to what happened in Faculty of Computer (FILKOM) University of Brawijaya. They have been using Microsoft Excel to manage all of the corresponding letters until this time. In this way, the distribution of letters has become less effective knowing that there is no integration between units/divisions. Oftentimes, the distributed letter is stopped because of some reasons. It could be that the receiver is not available at that time, or there is no information whether the letter has already been handled or not. These kinds of problems can be solved by developing a web-based letter management system where each unit is integrated to one another. In this way, the distributed letter and its monitoring can be easily done without considering place and time. Waterfall model process is used by the author in developing the software. In requirement engineering phase, there are found 33 functional requirements and 1 non-functional requirements. Based on the requirement engineering result, system is designed to be implemented in the next phases. The testings performed are unit testing, integration testing, and validation testing that result 100% valid in all test scenarios. And based on the compatibility testing, it is known that the system worked with no problems occurred in 73% of 11 versions of tested browsers.

Abstract

Smartphones with powerful camera sensor capabilities can be used to analyze photos and object recognition. Food is one of the popular photography objects and seeing it makes you want to cook or taste it. Cooking requires recipes as a tool to make dishes because not everyone knows how to make dishes. Food recipe search techniques with food image input are needed because not everyone knows the name of the food made. There are several steps in the method carried out to do the introduction of food types namely preprocessing, feature extraction using the Color Moments and Gray Level Counseling Matrix (GLCM) method, feature selection using the Information Gain method and classification using the Weighted K-Nearest Neighbor (NWKNN) method. Tests were carried out to determine the accuracy of the NWKNN method and also to know the effect of the Information Gain feature selection. The results of testing with the K-Fold Cross Validation method obtained the highest average accuracy of 92.37% by dividing the test data by 30, the number of features by 10, the value of k on the NWKNN by 3 and calculating distances using Cosine Similarity. On other hands, the testing of the Information Gain effect resulted in the highest accuracy of 86.96% with the 15 best features. It can be concluded that the NWKNN method can answer the problem of unbalanced data and Information Gain can find out the best features for classification.

Abstract

In Malang City, organic vegetables can be found in various places such as supermarkets, organic vegetable stores, and farmer groups. Prices and types of vegetables differ from one place to another. Due to many places that sell organic vegetables, people are confused to determine organic vegetable stores. To solve this matter, the researcher built a recommendation system for organic vegetable shop in Malang based on location. The system is built in the form of an android application because many people have used an android device, and an android device has a GPS (Global Positioning System) sensor that can be used to find out the location of an android user. In determining the place of recommendation, the system uses the TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method with four criteria, namely, distance, price, variety of vegetables, and rating. Based on black box testing, the result shows that the system has 100% valid functionality. In testing algorithm validation, a matching between the manual calculation of the TOPSIS method and the results of the system has been done, and the results are the system 100% compatible with manual calculations. The last test is rank consistency by comparing the recommendations from 5 alternative and the recommendation from 6 alternative. The results of rank consistency testing show that the implementation of the TOPSIS method on the recommendation system for organic vegetable shop in Malang has consistent results.

Abstract

The Journal of Information Technology and Computer Science (J-PTIIK) Development of Brawijaya University is a repository of scientific journals that contains scientific writings from students of the Faculty of Computer Science Universitas Brawijaya. J-PTIIK is a repository of scientific journals supported by an open source journal management platform, the Open Journal System (OJS). In the application of the journal to be included in the repository, an editor must check it by checking all the files entered in the OJS and checking whether the scientific journals uploaded in the OJS are the same as the research done in FILKOM's thesis system. Journal editors must open two different applications to check the correctness of data from a student's scientific journal. To get student data from the FILKOM thesis system the editor must search the name of the student to get the data. This is not efficient because journal editors examine journals by opening two different systems and will take longer if there is a high number of students making publications. By integrating the two systems the editor is expected to simply access one application. This service was developed with one of the micro frameworks, namely the slim framework. The results of unit testing, integration testing and validation testing resulted in a 100% valid value and efficiency testing increased 10.79%
