Rifa Rufiadi and Alfatihah Reno (BPS-Statistics Indonesia)
Introduction
BPS-Statistics Indonesia never published domestic tourism data at Regency/City level due to expensive and huge work burden, while the data became more important and demanding by policy maker and business.
Compared to household survey for domestic tourism, using Mobile Position Data can reduce cost more than 60 %, cover more origins and destinations, get near real time data, get by product data such as commuters and circler travellers.
This 2018 year, as pilot we run both ways of collecting domestic tourism data, household survey and Mobile Position Data, while Asian Games event analysis 2018 was done as part of tourism.
To cope the limitation of MPD such as no expenditure data, digital survey was conducted using selected sample indicated by Mobile Position Data
BPS expects to substitute surveys with timely and more accurate digital data collection in the future
Sample
Household Survey
Distribution sample 30.000 census block,
50.000 traveller
Listing, chose eligible sample, estimate population
face to face interview
Using MPD & digital survey
Distribution sample All census block (more
than 800.000) +/- 1.799.342 subscriber
All domestic tourism subscribe to MNO, estimate for the non subscriber
Ground check
Enumerator
Household Survey Minimum :
8.000 x 4 = 32.000 man survey
Recruitment Training Questionnaire & manual Office supplies
Quarterly, memory laps Resistant from
respondent Remote area problem,
difficult to be reached
MPD & Digital Survey
No need enumerator,reduce burden
Monthly (timeliness), even daily data
Fact, real data(accuracy)
Cost Benefit
Household Survey
Rp1.300.000,-/ Census block
Rp800.000,-/ respondent
No learning process
MPD & Digital Survey
Rp18.750,-/Census Block (1,4%)
Rp8.300,-/respondent (1%)
Give experiences to BPS’s data scientist
1 US $ = Rp 15.000
The Process Prepare the algorithm and scripts
Implemented to 66 volunteers
Compare Household survey result with MPD
Increase data quality (level of disaggregation and accuracy)
Event Analysis of Asian Games (foreign and domestic visitors) at the Venue (GBK and JSC)

Algorithm to identify Tourism Trip
Generate “stay point” from raw data
Remove usual environment except Home (Work, Second
Home (Circular), etc.)
Create sequence of trips from “stay point” with
duration > 6 hours
Identify each destination visited with duration > 6
hours on each trip
Identify the main destination from each trip based on the
longest duration of stay
Result :
- Matrix of main destination with average length of stay
- Matrix of all destination with average length of stay

WORK Validation/Verification
• Further verification is carried out to determine the place of daily activities. All stay points detected as work / school locations are asked to be corrected.
• First verification is done to determine where the person is staying. All stay points detected as home locations are asked to be corrected.
Acuracy of Home Detection of the Volunteers
Accuracy of home detection is 85,83% (rank 1)
Accuracy of home candidate rank
