In most cases, their vision tends to be limited by the status quo. Eliciting a complete set of requirements that fulfil every gap and withstand scrutiny during validation is challenging. Hence, it is important to consider various factors influencing the success of requirements engineering. This paper identifies and prioritizes multiple critical success factors of requirements engineering using the Analytical Hierarchy Process. The initial model was developed from literature review and validated using evidence from an empirical study. Quantitative data was collected through a questionnaire and then analyzed to rank the success criteria and critical success factors. The results show that the user satisfaction is the most important success criterion, while the clear definition of project scopes and goals is the most critical factor for the success of requirements engineering.","PeriodicalId":32357,"journal":{"name":"Jurnal Sistem Informasi","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46558587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The respondents were 516 individuals who had used a PHT application, such as Samsung Health, iOS Health, or MiFit. Data processing was done via using partial least squares–structural equation modeling (PLS-SEM). This study uncovered factors that can affect intention to use PHT applications, including perceived usefulness, social influence, facilitating conditions, hedonic motivation, habits, performance risk, and self-health awareness. It was found that perceived ease of use and self-reported health condition do not affect the intention to use PHT applications. This study can provide guidance on PHT application service providers for ensuring data accuracy, increasing user satisfaction when using the applications, and preventing privacy violation.","PeriodicalId":32357,"journal":{"name":"Jurnal Sistem Informasi","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46212003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper aims to adapt and test the reliability and validity of the Students’ Preparedness for the University e-Learning Environment questionnaire developed by Parkes et al. into Bahasa Indonesia.  The original questionnaire covers a wide range of competencies relevant to e-learning preparedness for university e-learning environments in three dimensions. Prior to reliability and validity checking, pilot testing is conducted to test the unidimesionality of the instrument and the rating scale. An item-match analysis test is also carried out to observe the suitability of each item. Then, the final version of the questionnaire is administered to a large representative sample of respondents for whom the questionnaire is intended. The results show that, with a total of 1446 students from a public university in Indonesia as respondents, the adapted questionnaire is valid and reliable.","PeriodicalId":32357,"journal":{"name":"Jurnal Sistem Informasi","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46022587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Primary data collection was carried out by means of observation and in-depth interviews with research informants by purposive sampling. To increase the credibility of the data use source triangulation. The research informants consisted of the head of the family health services section, the head of the health centers and the midwife as the user of the e-cohort.  Thirteen informants (11 women and 2 men) participated in the study. Most informants can use the core functions of the e-cohort app navigation menu. The study proposes that the perceived perception of ease of use may not be in line with the perceived expediency of explaining variations in the successful acceptance of MCH e-cohort applications. The study also found that there were differences in outcomes between user perceptions at the operational level and policy makers at the managerial level. In general, the analysis collects several types of obstacles and potentially problems that negatively affect the usefulness of the e-cohort application : not being able to make the work of midwives easier and faster, ineffective and not so much to increase the productivity of performance. With regard to ease of use, users feel that the e-cohort can be easily learned and used.  The e-cohort is considered to have value as a system that makes the work of midwives more difficult and hinders the work, however, the appearance, elements, features and design are perceived to be quite easy to use. In addition, users also highlight the need to consider how the system can be implemented in order to minimize the impact and optimize usability","PeriodicalId":32357,"journal":{"name":"Jurnal Sistem Informasi","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42096363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

End user may not realize if their machine is compromised by malware. It could be the anti-malware mechanism is not working properly, such as the anti-virus is not updated or there is a zero-day attack. Therefore, it is necessary to detect the presence of malware on end-systems devices or the existence of zero-day attack in the local network. Implementation of honeypot as a security sensor that collects malware attack data in the form of malware files and malware hashes can be used as signatures for scanning and detecting malware. This research utilizes a honeypot as a security sensor to catching malware. The malware hash from the honeypot is used to scanning and detecting the presence of malware on the end-system in a local network such as a PC or server. Furthermore, Yara helps clarify the type of malware found by scanning suspected files. The results of scanning and detecting of malware by Yara will be reported to the appropriate authorities via Telegram application channles.

This creates new problems, as differences must produce relevant information. Of course, system integration will be required. Web Service is a system integration solution that does not consider the platform, architecture, or programming language used in different sources. The security of web service is considered not yet implemented. The JSON Web Token (JWT) technology is an authentication mechanism for web service and will have a significant impact on data security. This implementation optimizes JWT security with the HMAC SHA-256 algorithm. Testing is conducted on two information systems by comparing the performance size when JWT technology is applied to Tim Bebersih Masjid Information System.
