Energy Statistics of Indonesia
Energy statistics is one of many statistical activities conducted by
BPS, under the 1997 Statistics Acts No 16. The purpose of
conducting energy statistics is to provide data as the input for
constructing Indonesia GDP, for the government institutions
(ministries) need (certain purposes), and for other national and
international users’ need.
The enumeration unit of the energy statistics is a company
producing energy, i.e.: petroleum company, electricity company,
fresh water company, city gas company, and coal company. The
complete enumeration method is applied for collecting data and it is
implemented by direct interview, mail, e-mail, and/or fax.
The implementation of data enumeration is performed every year
and data publication is presented annualy.

 Subject Area:
The energy statistics covers petroleum statistics, electricity statistics, fresh
water statistics, city gas statistics, and mining of non petroleum and gas
statistics.
 Reference Period and Frequency:
The activities of the energy statistics is yearly (Jan to Dec) and it has been
conducted since 1980. BPS publishs energy statistics annually.
 Timelines
The interval time between the end of the reference period and publication is
less than 2 months. For example: 2009 data, surveyed in 2010 (until
December), and published in January/February 2011.
 Punctuality:
The time lag between the planned publication date and the actual publication
date is one month.

 Regional Level:
The lowest regional level of the availibility of the energy
statistics for public domain is at provincial level
(geographically, Indonesian administrative area is devided
into 33 provinces)
 Legal Authority:
All of statistical activities conducted by BPS Statistics
Indonesia are under the 1997 Statistics Acts No. 16.

 International reporting
• Energy statistics data is annually submited to UNSD.

Background and purpose
 Purpose
The purpose of producing energy statistics is for:
• constructing Indonesia GDP,
• providing the data needed by Indonesian Government
Institutions (Ministry offices) and private companies,
• other users need, such as: international agencies,
researchers, university students, public, etc.
 Users and applications
• National Account Directorate and government institutions
• United Nation, Japan, etc.

Concepts, variables and classifications
 Definition of main concepts and variables
The definitions of variables used in energy statistics apply
the definition of UN Manual, which is adjusted to the local
condition.
 Classification scheme
Classification of energy statistics applies KBLI (Klasifikasi
Baku Lapangan Usaha Indonesia 2009) which is adopted
from ISIC Rev-4.

Statistics Production
 Population
The population is all companies producing energy, those
are: petroleum company, electricity company, fresh
water company, city gas company, and coal company.
Reporting unit is the enumerated company.
Observational unit is the enumerated company.
Analitical unit is the enumerated company
 Data sources
The source of energy statistics data is from the
company producing energy (petroleum, electricity,
water, gas, and coal), by carrying out direct data
collection.
BPS. Statistics Indonesia
Mudjiandoko – Director of Industry Statistics
 Sampling
The survey is implemented by using sampling frame
which is obtained from the energy company directory
constructed by BPS and updated annually. The data
collection method is complete enumeration.
 Collection of data
The data collection method is by direct interview, mail, email, and/or fax.
 Control and revision
In each data collection, the results of the field survey are
then examined and checked by enumeration supervisor.

 Estimation
There is no estimation method applied, since the data
collection is carried out by complete enumeration
method.
 Resource requirements
The activities of energy statistics conducted by BPS
Statistics Indonesia is fully funded by the government
budget, for the employes’ salary, equipments needed,
and operational cost.

Source of error and uncertainty
 Measurement and processing errors
In order to be able to minimize the measurement error, it is assigned an
enumerator supervisor for a group of enumerators in each implemented
survey for examamining and checking the survey results before being
processed. There is validation and revalidation steps to produce clean
data before the data is processed.
 Non-response errors
The survey results is catagorized non-response if:
• The enumerated company does not send back the survey
questionnaire. In this case, revisit is conducted to re-enumerate.
• The enumerated company can not or does not want to fill out some
data-items in the survey questionnaire. Data imputation is applied.

Comparabillity and Coherence
 Comparability
The energy statistics survey is conducted every year since 1980 and it covers
all 33 provinces, so there is relativelly no difference/change in the survey
implementation, in terms of geographycal coverage and the duration over year.
 Coherence
The energy statistics survey is implemented once in a year for every year by
using the same survey questionnaire form and complete enumeration method.
So. the coherence of this annual survey for the same enumerated sampling
units tends to give relatively similar results except for the volume of the dataitem questioned.
There is no coherence of the energy statistics survey conducted by BPS to
other institution/organization, because there is no other institutions conducting
energy statistics survey. The office of Ministry of Energy and Human
Resources obtains official reports from the energy companies, and it is also
used by BPS as the secondary data.

Availability

Publications and other links
The data and publications related to the energy statistics of
Indonesia can be obtained in the form:
• Hard copy (publication books)
• Soft copy (data and publication books)
• Homepage: http//www.bps.go.id

Microdata
All statistics data are stored in the DW (computer data
warehouse). Any request of the data, certain condition applied,
can be address to the Director of Statistics Information System,
BPS Statistics Indonesia.

 Documentation
Metadata documentation of energy statistics is available for public,
which can be requested, certain condition applied, to Director of
Industry Statistics, BPS Statistics Indonesia.
 Confidentiality
• Individual company/establishment data is very confidential,
except for its name and address
• The published data in terms of aggregated data is for more than
2 (two) companies. If the data consist of less than 3 (three)
companies/establishments, then they are combined to other
establishments/companies having nearest ISIC code.
• Directory publication contains only name and address of the
company.

Data Collection Issues
Given conditions:
The ultimate units or enumeration units of the energy
statistics survey are the companies which produce energy,
i.e: petroleum company, electricity company, city gas
company, fresh water company, and coal company.
Issues:
Two main issues giving impact to the data resulted are:
 Response rate, which tends to be low.
 Timeliness, which tends to exceed the survey scheduled.

Summary
Given conditions:
 Energy Statistics of Indonesia which are conducted annualy consists
of petroleum statistics, electricity statistics, city gas statistics, fresh
water statistics, and mining of non petroleum and gas statistics.
 For several years collecting data of the energy statistics to the
companies, it is indicated that there are two main issues which can
give significant effect to the data resulted, they are low response rate
and exceeded time schedule determined.
 The occurrence of low response rate and exceeded time schedule are
caused by the perception of the companies to the survey, the quality
of survey enumerators, the problem of document delivery, and the
internal management .

Enhancement:
In order to be able to increase the response rate and
conduct the energy statistics survey more timely, it needs
to be considered to:
• train statistics officer in energy statistics knowledge
• begin developing and applying an e-energy statistics
• provide suitable budged for carrying out the survey
activities of the energy statistics, especially for
conducting statistics survey socialization to the survey
respondents (companies producing energy).
