Organizational Structure
There are
33 BPS provincial offices
344 BPS regency offices and
96 BPS city offices.
they are the vertical representative offices of BPS.
At sub-district level, BPS employs a statistical staff (sub-district level Statistical Coordinator).
Technically and administratively, BPS regional offices are directly under the control of BPS-Statistics Indonesia.
The number of BPS staffs is 13,465 (as July 2008)
1,466 persons in BPS Head Quarter (11%)

Population census: in the years ending with 0. previous population census: in 1961, 1971,
1980, 1990, 2000. The next Population Census would be in 2010
Agricultural census: in the years ending with 3. previous agricultural census: in 1983, 1993,
2003. Economic census:
in the years ending with 6. previous economic census: in 1986, 1996,
2006.
Census in Indonesia
• Using Mainframe:
• (NEC ACOS 500 in 1980)
• (NEC ACOS 1520 in 1990)
• Batch Processing (not interactive)
Data Processing Support for Population Census 1980, 1990
1. Decentralized & Distributed Data Processing:
• Encourage End-users Computing: subject matter units are entitled to process their own survey under coordination of data processing division.
• Develop application in-house by HQ & decentralize operation to Regional offices.
• Implement Distributed / Client-Server Data Processing Model.
2. IT Department (Directorate of SIS) focuses on IT infrastructures & complex DP Systems such as Censuses.

Data Processing Policy(after elimination of Mainframe)
• PC based Client-Server Data Processing
• Using Scanner: Kodak DS3500• Speed: 3500 forms / hour• Use of OMR, ICR: Nestor
Reader• ICR Ascent-Capture: started in
2003 (Census of Agriculture).
Data Processing Support for Population Census 2000
PC 2000 Data Capture Stages
Scan documents (produce image file)
Recognize image (produce ascii characters)
Verification & Correction (operators decide characters ambiguous to recognize engine)
Completion completeness check
Release save into database
Experience from PC 2000• Unexpected low quality of enumerator’s
handwriting to recognize by ICR• Unable to recognize characters correctly
– Rejected too many values (too high confidence level)
– Accepted incorrect values (too low confidence level) realized from tabulation output
– Should check-digit help to increase accuracy ?• Ineffective learning engine• In a LAN environment using MS-SQl Server, 4
concurrent scanning processes slow down the whole DP activities consisting of 3 recognize stations, 10 correction stations,and 25 computer editing stations.
Experience from PC 2000• Extra work to erase & rewrite Census Form• Powder from rubber eraser stick on Census
forms & affected Scanner performance• Costly maintenance effort of Scanners
which spread over all provinces• Relatively high cost (investment) for Data
Capture H/W& S/W• However, Data Capture using scanner was
able to shorten Data Processing Completion Time.
• It was not easy to find out well motivated enumerators & Data Capture operators.
PC2010 Data Processing Plan
Main Documents:• Short Form : L for Listing & basis for 10%
sample, using data entry (DE), : C using scanner,
complete enumeration (100%) of households & members
• Long Form : S using data entry / scanner, 10% sample.
Estimation:• No of Districts / Regency = 456
• No of Sub-districts = 5,901
• No of villages = 72,084
• No of Census Blocks = 658,308 (in year 2000)
• No of smallest Administrative Areas (SLS) = 900,000
• No of households = 64 million
• No of population = 236 million

PC2010 Data Processing Plan (cont)
Issues on existing Scanners:
Kodak DS3500 procured for PC 2000: 79 units
About 60 % of them need spare-parts replacement
Spare-parts are discontinued. (Dicom Singapore eager to reserve all available spare-parts to BPS)
Running out of Ascent Capture Counter (dongle) limit
Operable uncertainty for PC 2010
1. Utilize scanners with character recognition technology (OMR, OCR, ICR), focused on OMR.
2. Expect ICR with better Learning Engine capability.
3. Procurement of Scanning H/W and S/W in 2009.
4. Formation of 8 Data Processing Centers.
5. Utilize SMS facility for transmitting and accessing data, as well as monitoring data collection activities.
6. Utilize web-based application for monitoring data processing activities.
7. In 2008, all of 33 province level offices and some (34) district / city level offices are connected using Virtual Private Network (VPN).
