The development and progress of IT-based information technology is very rapidly developing and has a very important role. Information systems are a necessity for agencies to utilize information as a basis for data administration and processing. To meet these needs, the agency conducts activities related to computer-based information systems as a tool to increase employee creativity. This system is designed to handle the transaction of escort and payment salary calculations and can guarantee validiity, complete authorization, classification of assessments, timeliness of each payroll transaction. In the Middle School Nusantara Wisata Respati Middle School still uses a manual payroll system, which is Microsoft Excel, so that people who are not authorized to enter and view data and can change the impact will disrupt the activity in processing salary data.

Abstract In this chapter, we focus on mathematical models of tuberculosis epidemiology (TB) that include interactions with HIV and an explicit representation of transmission. We review the natural history of TB and illustrate how its features are simplified and incorporated in mathematical models. We then review the ways HIV influences the natural history of TB, the interventions that have been considered in models, and the way these individual-level effects are represented in models. We then go on to consider population-level effects, reviewing the TB/HIV modelling literature. We first review studies whose focus was on purely epidemiological modelling, and then studies whose focus was on modelling the impact of interventions. We conclude with a summary of the uses and achievements of TB/HIV modelling and some suggested future directions.
