 
the  chief  of  Deli  Administrator  Maatschappij  and 
C.W. Janssen, the director of Senembah Matschappij 
Company  and  Medan  Tabak  Matschappij  (Alkema, 
1929).  At  the  time  of  its  establishment,  this 
institution was led by a doctor, who was on duty in a 
plantation  company  namely  Senembah 
Maatschappij. The doctor is dr. W.A. Kuenen. He is 
the  one  who  put  the  principles  of  institution  and 
policy  direction  of  this  laboratory.  In  addition,  he 
also  contributed  much  in  a  study  about  tropical 
disease  which  infected  many  labors  in  plantation 
(AVROS,  No.  358).  Along  with  W.A.P.  Schuffner, 
they  discovered  the  correlation  between  the 
environmental  condition  and  the  cause  of  a  disease 
or epidemic. Some previous researches  and policies 
were  made  by  them  then  followed  by  other 
plantation companies (Schoute, 1934).  On the other 
hand,  they  also  had  decreased  the  level  of  labors' 
death  in  Senembah  Maatschappij  plantation  from 
136 death cases of every 1.000 labors in 1891 and it 
became  10  death  cases  of  every  1.000  labors  in 
1906.  They applied several  policies and  regulations 
such  as  maintenance  of  hygiene  in  barrack  and 
labors'  residence,  concerning  on  nutritious  and 
adequate  food,  and  treating  a  sick  labor  with  good 
facilities  and  infrastructures  such  as  hospital  and 
clinic in plantation (Schuffner and Kuenen, 1910). 
Pathological laboratory had aim to spread widely 
and give information about public sanitation issue in 
East  Sumatera.  Besides,  the  propaganda  of  health 
and  hygienic  life  style  was  shared.  That  laboratory 
was  functioned  to  help  doctors  or  medical  experts 
conducting  research  in  this  laboratory.  In  addition, 
this  laboratory  also  provided  help  to  the  doctors  in 
conducting  a  research.  Therefore,  this  laboratory 
would  have  qualified  doctors  in  bacteriology  and 
serology.  There  were  several  activities  done  in  this 
laboratory  such  as  prophylaxis  vaccination  (disease 
prevention),  treatment  therapies  and  preparation  of 
diagnosis of disease cases (AVROS, No. 358). 
Pathological  laboratory  is  a  medium  to  conduct 
research  and  to  diagnose  various  tropical  diseases 
existed in East Sumatera plantation at the end of 19
th
 
century. The research in it was done in order to find 
the  cause  of  a  disease,  the  correlation  between 
symptoms  and  the  environment  with  the  epidemics 
of  disease  in  one  region  specifically  plantation 
(Volker,  1928).  In  its  development,  this  institution 
improved gradually. The improvement could be seen 
from the number of conducted researches was 1.311 
in  1910,  and  the  highest  improvement  occurred  in 
1930  become  30.372,  but it  got  downtrend in  1934 
which became 28.553 (Kouwenaar, 1936). 
In the early stage of operation of this laboratory, 
all  administrative  activities  were  entirely  supported 
by  the  company  of  Deli  Maatschappij,  Senembah 
Maatschappij  and  Medan  Tabak  Maatschappij. 
Gradually,  along  with  the  development,  there  were 
many plantation companies, private plantations, and 
plantation hospitals turned to be the members of this 
laboratory. The  contribution of the  members was to 
give  donation  or  membership  fee  every  month.  In 
the  period  of  1909-1920,  it  was  recorded  that  45 
plantation  companies  were  the  members  of  Medan 
pathological laboratory (AVROS, No. 358). 
The number of members progressively increased 
particularly from rubber plantation companies. Each 
member  donated  fund  to  this  laboratory.  The 
calculation  of  contribution  was  based  on  the  large 
number of  labors  in each  plantation. The  plantation 
which was the member of institution was obliged to 
pay  contribution  fee  of  f.  0.50  for  each  labor  per 
month  (Wolff,  1930).  Except  the  contribution  fee, 
there  was  a  contribution  from  Netherlands  colonial 
government.  In  1918,  Netherlands  colonial 
government issued a policy to assist operational cost 
for  the  institution  by  giving  f.  500  every  month 
(AVROS,  No.  358).  The  next  stage,  operational 
budget  escalated  every  year.  And  then,  the 
management  and  distribution  of  the  operational 
budget  of  the  institution  was  controlled  by 
governmental  health  institution  namely  BGD 
(Burgerlijken  Geneeskundige  Dienst)  (Alkema, 
1929). 
On 1
st
 November 1920, there  was a transfer and 
collaboration  occurred  between  laboratory 
institution  and  plantation  entrepreneur  association 
i.e.  DPV  (Deli  Planters  Vereeniging)  and  AVROS 
(Algemeene  Vereeniging  Rubberplanters  ter 
Oostkust van Sumatra). This transfer was continued 
even  though  the  plantation  condition  was  less 
profitable in recent years. By this transfer, it caused 
a  change  in  the  formation  of  the  institution's 
management,  so  the  policy  issued  also  changed 
(AVROS, No. 358). 
In  the  organizational  structure  of  the  institution, 
it  incorporated  the  board  of  directors  which  was  in 
1921  consisting  of  2  representatives  from  DPV,  2 
representatives from AVROS, and 1 person was the 
director  of  laboratory  institution.  Moreover,  the 
institutional  structure comprised of the  director, the 
vice  director,  laboratory  doctor,  assistant  of 
bacteriology  and  serology  department,  and  the 
secretary.  Besides  the  organizational  hierarchy 
which  mostly  consisted  of  Europeans,  there  were 
also  staffs  and  employees  from  the  natives 
positioned  as  foreman,  laboratory  staffs,  assistants, 
attendants,  office  clerks,  photographer  and  drivers 
(AVROS, No. 358). 
The first director was dr. W.A. Kuenen who was 
on duty in the period of 1906-1916. During his era, 
the organizational structure and institute's duty were 
assisted by vice director dr. J.J. van Loghem starting 
from  1908  to  1909  and  then  dr.  H.  Vervoort  in
