Abstract

Information systems research for non-profit organizations is an opportunity to make a contribution to the field of information systems, the adoption of information systems in this field is relatively tedious and there are few studies that examine this area; consequently, there are several research gaps in the domain of non-profit organizations that need to be solved. This research will focus on the development of data warehouse architecture and business intelligence for non-profit organizations. In this study, the Soft Systems Methodology (SSM) technique will be employed to develop a data warehouse architecture and business intelligence. This research will interview twenty individuals to collect primary data, review organizational policy documents, and conduct an open-ended survey. The obtained data will then be qualitatively analyzed, resulting in the formation of rich picture diagrams, CATWOE analysis, and conceptual models, which will ultimately form a data warehouse architecture and business intelligence. This research has produced a microservices-enhanced data warehouse architecture and business intelligence for non-profit organizations.

Abstract

This research investigates disparities in access and representation within specialized high school admissions processes, focusing on public middle schools in New York City. Leveraging a dataset by a non-profit organization dedicated to increasing diversity in specialized high school admissions, the study employs exploratory data analysis and unsupervised learning techniques to identify schools with high levels of underrepresentation and academic potential. The analysis reveals significant disparities in access to specialized high schools, with certain demographic groups and schools facing barriers to entry. Through k-means clustering, schools are categorized based on their academic performance and demographic composition, enabling targeted intervention strategies to address disparities in access and representation. The research proposes general use towards education, including on-campus interventions, awareness campaigns, and regional information sessions, aimed at fostering equitable access to specialized high school programs. This study contributes to the broader discourse on educational equity and offers valuable insights for policymakers, educators, and researchers seeking to promote diversity and inclusion within educational systems.

Abstract

Software quality is affected by its development process. The software development process, in general, goes through several stages, including project management, system requirements analysis, architecture, and design, implementation and testing. On each of these stages it cannot be separated from the process of capturing, storing, transferring and sharing knowledge between the developer and the stakeholders. This systematic review aimed to analyze the knowledge management process in the software development process. In this systematic review we used the Preferred Reporting Item for Systematic Review and Meta-Analysis (PRISMA) guidelines. We reviewed twenty-two works of literature from several publisher sources and analyzed the knowledge management process in software development. The analysis revealed that the knowledge management process has an essential role in improving the quality of software developed. As a conclusion of this systematic review, knowledge management is one of the factors in determining software quality.

Abstract

In Indonesia, vocational schools are less favored compared to K -12 schools. Unfortunately, graduates from vocational schools do not fulfill the minimum requirements set by industries, particularly in the current era of industry revolution 5.0. This revolution aims to establish society 5.0, where humans and robots collaborate closely to achieve improved work outcomes. One technique to enhance the proficiency of graduates and prepare them for the workforce is by implementing a mixed-reality system. that will effectively address a multitude of issues and significantly enhance the caliber of graduates and before the implementation of mixed reality (MR) systems, it is necessary to create system architecture diagrams to ensures that the system can be utilized not only in specific schools but also in any vocational school in Indonesia. This study comprises 5 participants, including experts from both the professional and academic fields, who possess extensive knowledge in the domains of metaverse, MR systems, and information systems. The methodology employed in this study draws inspiration from James Martin’s rapid application development (RAD). The result of this study is a validated system architectural diagram, endorsed by experts, which depicts a metaverse-based MR system designed specifically for vocational schools in Indonesia

Abstract

Evaluation of e-Government is conducted to improve the efficiency, effectiveness, transparency and accountability of governance and public services. This study aims to evaluate the implementation of e-Government (e-Gov)in XYZ institution. The evaluation is divided into three types, first is analysis of maturity level using e-Gov Ranking Hold Indonesia (PeGI), the second type is evaluation of Information Systems Resources (ISR) with descriptive qualitative method, and the last one is analysis of system quality and information quality based on McLean and DeLone (2003) using analysis of Importance Performance Analysis (IPA). As a result, the overall assessment of PeGI from the five-dimensional measurement is good but it tends to be less threatened either. The dimensions of institutional, infrastructure, and application are categorized as good rank while the dimension of planning and policy are weak rank. Secondly, the evaluation results of ISR including hardware, software, netware, and dataware have good performance but the evaluation results of human resources need to be improved. Furthermore, from the IPA results, the low performance of sistem quality are reliability, accessibility, download time and efficiency and the low performance of information quality are timelines and up-to-date. Accordingly, XYZ institution need to make improvements that focus on information and communication technology (ICT) planning, human resources mapping and improving the quality and quantity in the field of ICT, as well as improving the system quality and the information quality to support the successful implementation of e-Gov in XYZ institution

Abstract

Computer science and engineering has provided many benefits that can be applied in our lives, such as in the field of automata theory, one of the largest areas related to the efficiency of an algorithm in solving problems in computational models. Text to Speech is a technology that converts text into sound using a phonetization system, phonemes that are arranged to form a speech to make computers able to communicate and interact with everyday spoken language. Data that need to be interpret is the health data such as body temperature, heart rate per minute, and oxygen levels. Text to Speech is very useful to be applied to blind aids who need information in the form of sound because of their limitations. For this reason, it is necessary to make an application that can read text-based data that is stored into a voice that can be heard by the blind, the method used in this study is Finite State Automata (FSA) which is used to split Indonesian words into words according to its syllable patterns and facilitate the pronunciation process which is included in the blind aids so that it is expected to help the visually impaired to be able to find out their health condition. in this study, the test was carried out using the Confusion Matrix method, while the results obtained were 97% accurate.
