Abstract— In Indonesia, there is a special agency tasked with
dealing with the misuse of prohibited goods, namely the National
Narcotics Agency, abbreviated as BNN. Apart from being at the
center, BNN is also at the provincial level. At the National
Narcotics Agency, there is a section or section that has a special
function to manage the supervision of prisoners and evidence in
the form of narcotics. The problem is, the administrative process
is still irregular, archives are difficult to find, and several other
important things, which are certainly very influential for the next
process and follow-up. This study aims to help design a system
that can manage the process of monitoring prisoners and
evidence. For the research method, the author uses a prototype
model, Model View Controller (MVC), and User Acceptance Test
(UAT). The results showed that the system can work well in
assisting the process of monitoring prisoners and evidence with a
percentage of 54.29% strongly agree and 64.00% agree with the
developed system model.
