Blacklist Author

Effective from 2023, the Journal of Information Systems and Informatics will introduce a blacklist in accordance with its publication process policy. This blacklist will comprise the names of authors and titles of articles that were submitted to the Journal of Information Systems and Informatics, underwent the review process, but did not respond. Such disregard for the journal's submission requirements has resulted in an unnecessary waste of time for the Editor and Reviewer. Provided below is a comprehensive list of the names, titles, and abstracts of the affected articles.

Impact of Social Influence Factors In Acceptance Rate of Valorant Game

Firman Herdiansyah, Togar Alam Napitupilu


VALORANT is an online team-based first-person shooter game developed by Riot Games. Currently VALORANT is popular among gamers because the game is similar to the Counter Strike but is given a skill set like the Overwatch. Now players on Indonesia are 560k player which so big and interesting to know the factors of this phenomenon. This study aims to determine the factors of social influence impacted the acceptance rate. The research model used in this study is TAM which is then modified as needed by using 6 constructs, namely Perceived Usefulness, Perceived Ease of Use, Social Influence, Attitude Toward Use, Intention to Use and Actual Usage as representatives of acceptance. The method of data collection in this study was to distribute surveys to 105 respondents in Jakarta. The results show that all variables affect Actual Usage except Perceived Ease of Use, although most respondents feel that this game is easy to understand. The results that have been discussed can be used as empirical recommendations to developers who want to make similar games.

There are several important considerations in designing a network, including availability, minimizing failure, and handling high traffic data. The current research aims to implement and evaluate the First Hop Redundancy Protocol (FHRP) system on star topology networks using EIGRP routing. The result shows the average performance difference of the master and the backup router in Virtual Router Redundancy Protocol (VRRP) protocol is 0,003 second, while in Gateway Load Balancing Protocol (GLBP) protocol is 0,076 second, and Hot Standby Router Protocol (HSRP) protocol is 0,075 second. The test in GLBP protocol shows a significant difference in packet loss between master and backup router about 12,07%, while in VRRP protocol is 0,07%, and HSRP protocol is 5,06%. The average throughput in HSRP protocol is stable with 0,60 Kbps in the master router and 0,90 in the backup router, while in VRRP protocol is not stable with 0,458 Kbps in the master router and 1,11 Kbps in the backup router.


Designing a Priority System User Interface for Elementary School Education Infrastructure Development Using Goal-Directed Design

Denny Jean Cross Sihombing


The distribution of educational infrastructure in Indonesia is not evenly distributed in Indonesia causes Indonesia to have a low quality of education. This study aims to design a user interface for the priority system for the development of educational infrastructure in elementary schools in Karawang Regency. The user interface design of this system is carried out using the goal-directed design method. The results of this study are user interface design for the entire system. That plays a role in assisting the decision-making process regarding constructing elementary education infrastructure in Karawang Regency, recording educational infrastructure data, and processing reports of damage to educational infrastructure at each Elementary School in Karawang Regency.
