weighted assets (RWA). Thus, the increase in CAR
can result in lower ROA, vice versa. In addition, there
are  other  assets  that  have  a  100%  risk  weight,  i.e.
fixed assets or other assets that do not contribute to
bank income. If an increase in the RWA is due to an
increase  in  assets  in  this  group,  there  may  be  an
increase in CAR followed by a decrease in ROA, vice
versa. This is because bank funds are used for assets
that  do  not  contribute  to  bank  operating  income
(Setyawati, 2016; Setyawati, Suroso, Rambe, et al.,
2017).
Some  CAR  studies  have  a  negative  effect  on
profitability (Hidayat  &  Abduh,  2012;  Setyawati,
2016; Wasiuzzaman & Tarmizi, 2009), while other
CAR studies have a positive influence on profitability
(Sufian & Abdul Majid, 2008; Sufian & Habibullah,
2010).
NPF has a significant negative effect on the ROA
of  Bank  Syariah  Mandiri,  as  well  as  NPL  has  a
significant negative effect on ROA of Bank Mandiri.
Regression coefficients that are marked as negative
indicate  the  less  problematic  financing/loan,  banks
tend  to  increase  in  profits.  In  some  studies  in  the
banking  industry,  non-performing  loans  or  non
performing financing as a credit/financing risk proxy
(Al-Omar  &  Al-Mutairi,  2008;  Ramlall,  2009;
Setyawati, 2016; Setyawati, Suroso, Suryanto, et al.,
2017;  Sufian  &  Habibullah,  2010).  The  results  of
empirical  tests,  statistically  indicate  that
credit/financing risk resulted in lower  profitability,
both  in  conventional  and  sharia  banks (Aburime,
2008; Al-Omar & Al-Mutairi, 2008; Alper & Anbar,
2011; Athanasoglou et al., 2005; Hassan & Bashir,
2003;  Kosmidou,  2008;  Olweny,  2011;  Ongore  &
Kusa,  2013;  Ramlall,  2009;  Setyawati,  2016;
Setyawati et al., 2015; Setyawati, Suroso, Suryanto,
et al., 2017; Vong & Chan, 2009). The greatest failure
of banks,  stems from the way banks recognize the
weaknesses  of  their  assets  and  create  reserves  to
remove  the  write-off  of  these  assets (Sufian  &
Habibullah, 2010).
BOPO  has  a  significant  negative  effect  on  the
ROA  of  Bank  Syariah  Mandiri  but  will  have  a
significant positive effect on Bank Mandiri ROA. The
negative signified regression coefficient indicates the
smaller  the  ratio  between  operational  cost  and
operating  income,  the  bank  tends  to  increase  in
profits, and vice versa. The operational activities of
the  Bank  will  be  less  efficient  if  operating  costs
increase higher than operating income and result in
decreased  ROA. Some  studies  have  found  that
operating  costs  have  a  negative  relationship,  so
management  cost  efficiency  is  a  prerequisite  for
improving  profitability  in  the  banking  sector
(Setyawati,  2016;  Sufian  &  Abdul  Majid,  2008;
Sufian  &  Habibullah,  2010;  Wasiuzzaman  &  Nair
Gunasegavan, 2013).
GDP  has a significant negative  effect on ROA,
both  for  Bank Syariah Mandiri  and Bank Mandiri.
The  negative  signified  regression  coefficient
indicates  the  smaller  the  GDP,  the  bank  tends  to
increase in profitability.
Gross  domestic  product  (GDP)  is  one
a  macroeconomic  indicator  in  measuring  the  total
economic activity of a country. GDP is expected to
affect many factors, especially with regard to supply
and  demand  for  loans  and  deposits.  Conducive
economic  conditions will  affect  the  demand  and
supply of banking services. However, GDP measures
only the material side, whereas the non-material side
can not be measured. This means that low GDP does
not  mean  that  people's  welfare  decreases,  because
there are non-material factors that affect.
Positive  influence  between  GDP  and  ROA,
consistent with previous research (Hassan & Bashir,
2003; Kosmidou, 2008; Setyawati, Suroso, Rambe, et
al., 2017; Setyawati, Suroso, Suryanto, et al., 2017),
and did  not support  the  argument  that  economic
growth  and  performance  of  Bank  Syariah  Mandiri
and Bank Mandiri are positively related.
The inflation rate has a significant negative effect
on  ROA  of  Bank  Syariah  Mandiri,  but  positively
affects  the  ROA  of  Bank  Mandiri.  The  negative
signified regression coefficient indicates the smaller
the  inflation  rate,  the  banks  tend  to  increase  in
profitability,  and  consistent  with  previous  research
(Kosmidou, 2008; Setyawati, Suroso, Rambe, et al.,
2017; Setyawati, Suroso, Suryanto, et al., 2017). If
the inflation rate is not expected, the bank may slowly
adjust  the  interest  rate.  As  a  result,  costs  increase
faster than bank income, which consequently has a
negative effect on bank profitability (Athanasoglou et
al., 2005; Bourke, 1989; Kosmidou, 2008; Setyawati,
2016).
4.4 Bank Syariah Mandiri and Bank
Mandiri: Performance Comparison
To examine the differences in Bank Syariah Mandiri
BSM) and Bank Mandiri (BM) performance, using
parametric  (t-test)  and  nonparametric  tests  (Mann-
Whitney  [Wilcoxon]  and  Kruskall-Wallis).  The
results are presented in Table 8.
