of tools that combines Open Innovation, Open Data, 
and  Open  Data  Services  paradigms  to  enable  co-
created  urban  apps(Emaldi,  Aguilera,  López-de-
Ipiña, & Pérez-Velasco, 2017). In Germany, mobile 
crisis  applications  are  being  used.  Mobile  crisis 
applications,  which  are  relatively  new  public 
services  for  citizens  and  are  specifically  meant  to 
spread  disaster-related  information  and 
communication  between  authorities,  organizations, 
and  citizens,  are  increasingly  being  investigated  by 
crisis  informatics(Kaufhold,  Haunschild,  &  Reuter, 
2020).  Contact  tracing  is  a  typical  surveillance 
technique  for  locating,  analyzing,  and  managing 
persons  who  have been  exposed  to novel infectious 
illnesses.  COVID-19  is  managed  through  mobile 
phone  apps  that  employ  a  digital  technology 
approach  known  as  "proximity  tracking"  (Pillai, 
Siddika,  Hoque  Apu,  &  Kabir,  2020).  The 
determinants  of  citizens'  future  use  of  government-
provided  mobile  applications(Reddick  &  Zheng, 
2017).  Citizen-government  applications  in 
information use, service use, and participatory use. It 
explores  the  impact  of  such  use  on  citizen 
compliance  and  the  mediating  role  of  trust  in 
government(Wang, Chen, Xu, & Leng, 2020). 
Based  on  this  explanation,  several  previous 
studies  focused  on  how  the  application  works  and 
the  determinants  of  people  using  government 
applications.  So  the  novelty  of  this  research  is  the 
focus  on  the  use  of  applications  launched  by  the 
government  to  improve  public  services.  Therefore, 
this  study  aims  to  explain  using  the  "SIKESAL" 
application created by the Jambi City Government to 
improve public services. 
2  LITERATURE REVIEW 
2.1  Smart City 
The  term  "smart  city"  refers  to  using  ICT  to 
sense,  analyze,  and  integrate  critical  data  from 
core  municipal  systems.  Smart  cities  may 
simultaneously respond intelligently to a variety 
of  needs,  including  daily  life,  environmental 
protection,  public  safety,  and  local  services,  as 
well  as  industrial  and  commercial  activity 
(Zhang, 2010). The phrase "smart city" refers to 
the idea of applying the "smart planet" concept 
to  a  specific  place  to  create  informative  and 
integrated  city  administration.  It's  also  the 
successful  combination  of  intelligent  planning 
principles,  intelligent  building  processes, 
intelligent  management  methodologies,  and 
innovative development strategies(Su, Li, & Fu, 
2011). 
The  way  cities  organize  policymaking  and 
urban expansion is changing due to information 
and  communication  technologies.  Smart  Cities 
use information and communication technology 
to  alter  city  infrastructure  and  services  in 
various  disciplines,  including  economy, 
environment,  mobility,  and  governance(Bakıcı, 
Almirall,  &  Wareham,  2013).  Intelligent  city 
policies  foster  new  methods  of  conceiving, 
organizing,  and  controlling  the  city  and  its 
flows while imbuing the city with a new moral 
order  by  establishing  technical  parameters  that 
distinguish between "good" and "bad" cities. As 
a  result,  the  smart  city  could  effectively 
generate docile subjects and political legitimacy 
processes (Nam & Pardo, 2011). 
2.2  E-Government in Public Service 
E-government  will  improve  public  services  by 
transforming  the  functioning  of  public  sector 
organizations.  E-government  can  improve 
public  service  delivery  by  boosting  efficiency, 
lowering operational costs, increasing access to 
services,  and  raising  consumer  satisfaction 
(Osei-Kojo,  2017).  E-government  is  constantly 
evolving  for  various  reasons,  including 
providing  high-quality  services  to  citizens  and 
businesses,  improving  public  sector  efficiency, 
reducing  government  administrative  burden, 
allowing  for  cost  savings  in  government 
administration,  and  increasing  government 
decisions and actions transparency. "The use of 
ICTs  in  public  administrations  combined  with 
organizational reform and new skills to improve 
public  services  and  democratic  processes  and 
strengthen support for public policy," according 
to  this  definition.  E-government  is  seen  as  a 
catalyst  for  improved  government  and  higher 
public value (Georgiadis & Stiakakis, 2010). 
E-government  applications  improve  the 
public sector's cost efficiency and effectiveness 
and  bring  about  a  revolutionary  change  in 
public  service  delivery,  administration,  and 
public involvement. Because of the use of  ICT
