Software Testing by Standard Software Metrics Method; Study Case "Mission Planner" as UAV Ground Station Software

This paper explains the testing of a complexity of software and complexity of flight data from Mission Planner as UAV Ground Station software. Tests were conducted using the software metric method. The analysis, testing, and calculations were applied using the method of software metric to investigate the complexity of the software and the flight data on Mission Planner. The tests were performed on three different OS (operation systems); Windows, Linux, and Mac. The result shows that Windows OS has the most reliable software environment and flight data than the other two software

WebGIS Application of Geospatial Technology for Tourist Destination in Malang

Tourism is a place of relaxation for people in which they can plan their sights based on Information. GIS-based information is increasingly important among tourists as it allows them to get to know places, and this has a deep appeal for travel planning. Malang is a famous tourist destination in Indonesia. The region is visited by a large number of tourists from various parts of the world each year. The number of tourists visiting Malang from year to year is always increasing by considering the number of tourism potential in Malang. However, in the absence of a Tourist Information System, tourists face various difficulties in finding various tourism information. Geospatial technology has changed every area of life and the tourism industry cannot be excluded. The purpose of this research is to develop an interactive and easy-to-use Geographic Information System (GIS) that enables tourists to get information about tourism objects. This research actively demonstrates the potential application of geospatial technology to explore tourist destinations with some detailed information

Usability Evaluation of E-Government Using ISO 9241 and Fuzzy Tsukamoto Approach

Usability is one of the important criteria to measure the quality of web applications. Therefore, it is pivotal to improve the usability of e-government by combining the features and attributes known to benefit the users in the context of its application. Usability is an important element that determines the success of e-government. Therefore, an approach that helps to determine the level of usability of an e-government quickly and accurately using soft computing techniques is needed. The study used the ISO 9241 and Fuzzy Tsukamoto approach to determine the level of usability of e-government. ISO 9241 was used as a standard to determine the aspects that would be used as an assessment when evaluating usability, while Fuzzy Tsukamoto was used as the calculation for automatically determining the level of usability of e-government. The aspects that are used as input variables are effectiveness, efficiency, satisfaction, and ease of use. The results of accuracy testing using RMSE (Root Means Square Error) towards 10 samples showed 90% accuracy. In addition, there are five different levels of e-government usability, very low, low, medium, high, and very high

Analisis Kerentanan Pencemaran Air Tanah di Kota Batu Menggunakan Analisis Multikriteria Spasial dengan Indeks DRASTIC

Groundwater and surface water are important sources of clean water which require an effective management. The use of groundwater and spring as exemplified by Batu City case – as part of Brantas watershed upstream – serves as raw water as well as clean water source for Batu City and Malang City population. Contamination of surface water and groundwater affects clean water supply as indicated by increasing nitrate, TDS, and E. Coli concentration. The study aims to analyze the vulnerability level of groundwater contamination by using spatial multicriteria analysis with DRASTIC index. The DRASTIC index is measured from some parameters such as surface water depth to water table, net recharge, aquifer media, soil media, topography, impact of vadose zone, and hydraulic conductivity to evaluate groundwater vulnerability. The results show that Batu City performs low vulnerability (86.93%) and medium vulnerability (13.07%) levels. The dominant factors affecting the level of vulnerability are groundwater levels, slope, and geological conditions across regions. Even though the DRASTIC modelling cannot specify the contamination levels of the different sources, this method is useful to identifying high-level contaminated land uses, managing water resources, and conserving groundwater sources

Development Framework for the Evaluation of Usability in E-Government: A Case Study of E-Finance Government of Malang

E-government is an effort to utilize information and communication technology especially internet to improve public service quality which generally implemented in a web based application. Usability is one of the important quality criteria for the success of a web. In this study we developed a framework for evaluation of usability in e-government consisting of  eight stages: (1) determining the evaluation objectives, (2) determining the usability aspects, (3) determining the metrics usability, (4) selecting usability evaluation method candidates, (5) determining the required criteria of the method to be evaluated, (6) evaluating the method, (7) selecting and making the instrument, and (8) evaluate usability.. The results of the application of this framework in the case study of e-finance resulted in two methods used: user testing and questionnaires. The evaluation of usability in e-government for e-finance case studies using the proposed framework results in usability level of e-finance in terms of effectiveness, efficiency, and user satisfaction are 96%, 92%, and 70 respectively. Which can be identified to be grouped into 16 problems consisting of aspects of effectiveness and efficiency
