Acute Respiratory Infection (ARI) is a very serious health problem in Indonesia. According to the Basic Health Research (RISKESDAS) the highest ARI diseases were in the provinces of East Nusa Tenggara (41.7%), Papua (31.1%), Aceh (30.0%), West Nusa Tenggara (28.3%), and East Java (28.3%). In Riskesdas 2007, East Nusa Tenggara is also the province with the highest ARI. The time period for the spread of ARI in Indonesia according to Riskesdas in 2013 was 25.0%, not much different from that in 2007 which was 25.5%. People are sometimes reluctant to go to the doctor and tend to ignore this disease. For solutions to these problems, we need a system that can help the community in diagnosing respiratory disorders so that later the community can more easily consult to anticipate a worse impact. One system that can be used to assist diagnosis is an expert system. This system is not to replace the position of an expert, but to promote the knowledge and experience of an expert.

Palagan is the name of a board game with a type of card game that has been distributed in the East Java region since the end of 2020 where the game is connected in one big narrative regarding the education of Covid-19 prevention behavior protocols equipped with attractive visual illustrations, Palagan is equipped with an Augmented Reality application as a complementary feature where the advantage is that it can arouse the interest of its users to learn and can make its users feel entertained, the contribution of this research is to map augmented reality content with the theme of health protocol education which is specifically intended for elementary school-aged children as an effort to minimize the gap in the level of compliance with the application health protocols in the community in urban areas.

Diamond Printing is one of the largest offset printing companies with 32 years of experience and is located in the city of Surabaya, East Java. Data from HRD managers explained that there was no report from observations related to employee work effectiveness in terms of coordination and synergy between employees as seen from the communication and collaboration relationships. The absence of data related to the effectiveness of the performance of CV employees. Diamond Printing in terms of communication network mapping is one of the obstacles faced by HRD in determining KPI (key performance indicator). By using the Social Network Analysis (SNA) method with the help of UCINET 6 software, it is hoped that some employees will have advantages, especially in collaboration and communication in group network structures. There are three parameters used in SNA, including: degree centrality, closeness centrality, and betweenness centrality. This study involved 104 respondents (the entire population) with a sampling technique using snowball sampling and a questionnaire as a means of collecting data. The results of this study indicate that most of the collaboration and communication network interactions are dominated by manager level employees and department heads. Based on these findings, an innovation is needed from all stakeholders from CV. Diamond Printing in developing effective communication methods between its members.
