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. BPS. Statistics Indonesia Mudjiandoko – Director of Industry Statistics Administrative information Official name of the statistics: Official name of the statistics dealing with energy statistical data is stated by Statistik Energi (Energy Statistics) Working unit and responsible authority: The working unit name which performs energy statistics matters (data collection, processing, publication) in the BPS organization is Sub Directorate of Mining, Quarrying, and Energy Statistics. This working unit is under the responsibility of Directorate of Industry Statistics, BPS Statistics Indonesia. BPS. Statistics Indonesia Mudjiandoko – Director of Industry Statistics 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. BPS. Statistics Indonesia Mudjiandoko – Director of Industry Statistics 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. Web address: http//www.bps.go.id International reporting • Energy statistics data is annually submited to UNSD. • Manufacturing industry data is monthly reported to IMF. BPS. Statistics Indonesia Mudjiandoko – Director of Industry Statistics 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. BPS. Statistics Indonesia Mudjiandoko – Director of Industry Statistics 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. BPS. Statistics Indonesia Mudjiandoko – Director of Industry Statistics 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. BPS.

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. BPS. Statistics Indonesia Mudjiandoko – Director of Industry Statistics 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. BPS. Statistics Indonesia Mudjiandoko – Director of Industry Statistics 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. BPS.

BPS. Statistics Indonesia Mudjiandoko – Director of Industry Statistics 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. BPS. Statistics Indonesia Mudjiandoko – Director of Industry Statistics The issues Company Company restriction Extra burden Refuse to respond Time consuming Enumerator No Survey Training Insufficient Wage Education Quality Moral Hazard LOW response rate DATA Exceeded time schedule Document delivery Management BPS. Statistics Indonesia Distribution Lost in delivery Damage Job position replacement Less attention/priority Mudjiandoko – Director of Industry Statistics 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 . BPS. Statistics Indonesia Mudjiandoko – Director of Industry Statistics 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).
