Abstract

Superior varieties are important supporting component in increasing national rice production. Each type of superior variety has different characteristics. Farmers need knowledge to be able to choose the type of rice they want while keeping rice production stable. To overcome the problem in determining rice seeds, one solution is to use data mining classification. The classification are using the decision tree method, with the C4.5 algorithm. C4.5 algorithm is an algorithm that builds decision trees from data with recursive patterns. C4.5 goes to each node of the decision tree, then selects the optimal branch until no more branches are generated. the algorithm can produce a classification of superior rice varieties needed to be planted in the fields. This research has input data in the form of flag leaves, grain shape, grain color, rice texture and texture. The input data is then processed by the C4.5 algorithm to produce outcomes that determine superior varieties of rice. The results of this study indicate that the classification performance of superior rice varieties is more influenced by the grain form attributes compared to other attributes. Meanwhile, the accuracy of the highest C4.5 algorithm in the k-fold 1 calculation was 28.571%. Meanwhile, k-fold 2 was 17.857%, k-fold 3 was 10.344% and k-fold 4 was 10.714%.

Abstract

Throughout 2019, until the end of October, BPBD of Malang City had recorded more than 184 disaster events, where the most frequent disasters were fires, landslides, fallen trees, puddles, earthquakes, and strong winds. The BPBD of the city of Malang also reported that during January - October the total damage and losses from the disaster were not less than Rp.10,695 billion. Lack of awareness of citizens about pre-disaster management and late reporting of disasters when disasters occur cause damage and losses that are caused to be very large. Based on these problems, the application of disaster management and reporting is needed so that people can report disaster events early so that they can reduce the risk of loss of life and property damage. The developed application must be easy to access and have an interface that makes it easy for the general public when accessing it. In developing this application, the writer uses the Waterfall methodology, the purpose is to use this methodology to work on applications that will be made based on the stages that have been previously designed. To make it easier to accommodate the modeling needs, the design of this application will be made in an object oriented manner and using an online map library to facilitate mapping of disaster data. In the process of implementation, the authors develop a website using the Codeigniter framework and a javascript-based online map library that is leafletjs and also google maps. Furthermore, the authors will test the application using White-Box Base-Path-Testing, and Black-Box Testing to determine the level of success of the implementation as well as testing the accuracy to find out how much the accuracy of a location from online maps compared with standard commercial GPS equipment. Based on the results of the study, it is known that the development of a geographic information system application based on website disaster management can accommodate existing engineering needs. And the results of the accuracy of GPS maps online with commercial GPS produces an average error margin of 39.7860457. The results of the design and implementation that have been carried out are proven to have an effect on making it easier for the community to submit disaster reporting.

Abstract

The quality of the interface in the Geographic Information System (GIS) was still not a major concern, whereas the quality of the interface was the prominent impact on the use of the Geographic Information System and some problems in the interface design contained in the Geographic Information System application were inconvenient to grasp by the user when is compared to the technical problems. This study aims to evaluate the interface of Geographic Information System processing applications (QGIS and MapWindow) so it known that the most optimal interface design could be identified by using the Heuristic Evaluation (HE) method to the function of geoprocessing tools. Based on the evaluation, QGIS application problems in the category "H1 - Visibility of system" and MapWindow application problems in the category "H7 - Flexibility and efficiency of use" were the particular concern for the evaluators. Besides, if the both applications were compared, the earlier evaluation showed QGIS application has 23 problems with an average severity rating is 2.0, this amount was higher compared to MapWindow application which only has 21 problems with an average severity rating is 1.9. However, in the final evaluation showed the different results, QGIS application only has 71 problems with an average severity rating is 2.02, this amount was lower than MapWindow application because the MapWindow application has 73 problems with an average of severity rating is 2.08.

Abstract

Natural disasters in almost every season hit Indonesia such as floods, landslides, fires and puso. Floods and landslides usually occur in the rainy season while fires and puso occur in the dry season. At present the frequency of floods and landslides increases as well as fires and pusos. Other natural disasters that often occur are geological disasters, such as earthquakes. Earthquakes in Indonesia often occur because they are flanked by three main plates namely the Indo-Australian plate. Eurasian Plate, and Pacific Plate. Efforts made to date use personal websites to disseminate geological map information. However, this business is still not neatly arranged. Meanwhile the Bandung Geological Directorate Agency does not have an official portal while the public can access geological maps throughout Indonesia. For this reason, plugins are developed from open source applications that can see geological maps throughout Indonesia in the form of plugins. Among the plugins developed by researchers are the Geological Map plugins. The Geological Map Plugin is an additional QGIS application that uses the Python programming language as the basis for making it. This plugin has a function to display the Geological Map of All of Indonesia. This geological map plugin can help find out the geological information of the region in Indonesia.

Abstract

Land Surface Temperature (LST) is the temperature found in the outermost layer of the soil surface. Information about LST is very important because LST is a factor that can influence global climate change. There are several ways that can be used to obtain SPT data, one of which is to use data obtained from satellites using the help of a satellite image data processing application such as QGIS. There are various plugins provided by QGIS to help its users. Plugins are additional tools designed to deal with various problems encountered. However, there is currently no plugin that automatically calculates the LST algorithm. LST algorithm calculations performed on the QGIS application still use manual methods so to get LST data requires a complex steps to produce LST data. To facilitate the process of getting LST data, a plugin is needed that helps users to automatically calculate LST. In this case, the QGIS SPT plugin is built using the Python with the hope that it can simplify and speed up the process of calculating LST data.

Abstract

Gapura UB is an academic portal mobile application to access academic information and services in the Brawijaya University campus environment. Based on the results of interviews with the developers, stated that the application has never been evaluated usability by testing usability to its users or conducted an inspection by an expert. Even though usability evaluation is an important element that makes it possible to add insight into usability problems in the application. This study aims to identify the usability problem of the application and compare the effectiveness of four evaluation methods used in this study: usability testing, interviews, surveys, and heuristic evaluation. Data is collected from users in the student category and expert evaluator. Details of the number of respondents used are usability testing (N = 10), interviews (N = 10), surveys (N = 110), and heuristic evaluation (N = 3). The four methods together identified a total of 44 usability problems: 45% through heuristic evaluation, 24% through surveys, 17% through interviews and 14% from usability testing, with a few similar findings. These problems are then categorized using Usability Taxonomy Problem (UPT) which divides the problem into 5 categories with details of 17 categories of visualness, 6 categories of language, 3 categories of manipulation, 11 categories of task-mapping and 7 others including the category of task-facilitation. The results of this study prove that the four methods are complementary, each method provides a unique insight to improve the usability of the application user interface. The researcher recommends using a multi-method approach when evaluating application usability because it can provide a more comprehensive representation of usability issues.

Abstract

MAGMA Indonesia is a platform for providing information on geological phenomena and potential natural disasters in the form of a website and mobile application developed by the Center for Volcanology and Geological Mitigation (PVMBG) under the Ministry of Energy and Mineral Resources (ESDM). Although functionally WEBGIS disaster is already good even though there are few users, the quality of usability cannot be ruled out and it does not rule out that there are some functions that are less attractive to users and become problems for the purpose of creating the system. This problem is part of the usability problem that exists in the MAGMA Indonesia application. So there is a need for more intensive usability testing to measure the quality of usability as empirical evidence of user responses to the system. The focus of this research is to evaluate usability on the MAGMA Indonesia website using the WEBUSE questionnaire and interviews. The flow method used to test usability is the User-Centered Design methodology approach. Usability test results show that the overall usability point is good, consisting of Content, Organization, and Readability 0.76, Navigation and Links 0.73, User Interface Design 0.83, Performance and Effectiveness 0.74. This research also produces recommendations for improvement solutions and additional features from the list of usability problems found by examiners and can be used as a reference for the MAGMA Indonesia website development team in making website usability improvements.

Abstract

This study aims to compare the effectiveness of three usability evaluation methods in usability problems on the Lowokwaru District website and to identify and classify the types of problems found. The method used is the usability evaluation method which involves users in it, namely: usability testing (N = 10), interviews (N = 10), and surveys (N = 30). The data collected by each method comes from site users who live in Lowokwaru District. The three methods identified a total of 35 usability problems: 46% via usability testing, 34% via survey, and 20% via interview method. These usability problems were classified into 5 categories and 21 problem topics. Usability testing was successful in identifying most of the problem categories (80%) followed by the survey (60%) and the interviews were successful in identifying the number of problem categories (40%). Usability testing is the most effective method to identify usability problems followed by survey and interview methods. Although usability testing identifies more usable problems than the survey and interview methods, no single method can identify all the problems that are visible to users. Therefore, a combination of these three methods is needed, because they complement each other in finding problems on a website.
