Passive acoustic monitoring of soundscapes and biodiversity produces vast amounts of audio recordings. However, the management of these raw data presents technical challenges and their analysis suffers from bottlenecks. A multitude of software solutions exist, but none can perform all the data processing needed by ecologists for analysing large acoustic data sets. The field of ecoacoustics needs a software tool that is free, evolving, and accessible. We take a step in that direction and present BioSounds: an open-source, online platform for ecoacoustics designed by ecologists and built by software engineers. Biosounds can be used for archiving and sharing recordings, manually creating and reviewing annotations of sonant animals in soundscapes, analysing audio in time and frequency, and storing reference recordings for different taxa. We present its features and structure, and compare it with similar software. We describe its operation mode and the workflow for typical use cases such as the analysis of bird and bat communities sampled in soundscape recordings.

Passive acoustic monitoring of soundscapes and biodiversity produces vast amounts of audio recordings, but the management and analyses of these raw data present technical challenges. A multitude of software solutions exist, but none can fulfil all purposes required for the management, processing, navigation, analysis, and dissemination of acoustic data. The field of ecoacoustics needs a software tool that is free, evolving, and accessible. We take a step in that direction and present ecoSound-web: an open-source, online platform for ecoacoustics designed and built by ecologists and software engineers. ecoSound-web can be used for storing, organising, and sharing soundscape projects, manually creating and peer-reviewing annotations of soniferous animals and phonies, analysing audio in time and frequency, computing alpha acoustic indices, and providing reference sound libraries for different taxa. We present ecoSound-web’s features, structure, and compare it with similar software. We describe its operation mode and the workflow for typical use cases such as the sampling of bird and bat communities, the use of a primate call library, and the analysis of phonies and acoustic indices. ecoSound-web is available from: https://github.com/ecomontec/ecoSound-web

User satisfaction is something that needs to be improved to realize the success of an information system. This study aims to redesign and recreate academic information systems in order to increase user satisfaction. The model used in application development is ADDIE because it has enough space in accommodating user participation, building trust in new applications through the data migration process, and changing culture through a limited set of applications. Meanwhile, user satisfaction is explored with the success of information systems model by DeLone and McLean (2003). The results of this study indicate that the ADDIE is an effective model in recreating academic information systems to increase user satisfaction. There is an increase in the influence of system quality, information quality, and service quality factors on user satisfaction from 65% in the legacy SIAKAD to 81% in the new SIAKAD. Meanwhile, user satisfaction significantly increased, namely an average of 17.7 in the legacy SIAKAD to 19.22 in the new SIAKAD.

Today the development of technology is growing, one of them is a mobile phone that is transformed into a smart phone, as well as a modern market that is developing and easily available and very comfortable physically, this development has involved traditional markets, the government continues to revitalize traditional markets using physical, technological developments are used as a means for developing traditional markets as an effort to facilitate transactions, get information quickly and on target. User interface Of course not separated from the appearance of the user interface Even the user interface is important, because the user interface can provide comfort and convenience for users in accessing any information for which the system can be obtained by the user. The purpose of this research is to create a traditional market online transaction system user interface. Where the research used in this study is the Goal Directed Design method which is a user interface design design method that fits the user's goals and needs. In this study there are five stages of experimental research, modeling, requirements, frameworks, and improvements. As well as the evaluation in this study using heuristic evaluation consisting of 10 principles. The final result of this study is a user interface design design that has been created for further development while the results of this study are 94% in the category of "Very Good".

Not all websites have fulfilled basic principles such as accessible and easy to use (usable). There are several measuring methods that already exist. In this research, the measurement is done by combining 2 measuring methods namely usability testing and eye tracking because the measurement is done with props that are eye tracking, so that at the same time we can measure the indicator usability testing and eye tracking metrics. So researchers to know the level of relationship or correlation between usability testing indicators and eye tracking metrics. The type of research conducted is a type of associative research with quantitative and qualitative approaches. Where both of these methods will result in quantitative data such as time on task, difficulty ratings, fixation duration mean and time to first fixation. Qualitative Data is obtained from playing the recorded results and conducting interviews to examine the results of eye movements when testing is the same as the opinions or perceptions of each participant. Results of a correlation test Pearson product moment acquired correlation or relationship between time on task with fixation duration mean, time on task with time to first fixation, difficulty ratings with fixation duration mean, difficulty ratings with time to First fixation. There are two possibilities of usability measurement performance indicators with eye tracking proving a significant correlation means measurement of usability using eye tracking can be used as an alternative in doing more usability measurement Accurate with significance levels > 2.048 in subsequent studies.
