A survey agency, Poltracking Indonesia, has expressed concerns that the ethics board of the Indonesian Public Opinion Survey Association (Persepi) has not been fair in explaining the differences in the electoral survey results for three pairs of candidates in the Jakarta gubernatorial election between the Indonesian Survey Institute (LSI) and Poltracking. "Persepi only clarified that the methodology and implementation of LSI could be analyzed well, but they did not explain how and why this analysis was possible," stated Masduri Amrawi, the Director of Poltracking Indonesia, in a statement on Tuesday (November 5, 2024). Masduri revealed that during a meeting with the Persepi ethics board, it was disclosed that LSI had replaced about 60 primary sampling units (PSUs), which is 50 percent of their total survey PSUs for the Jakarta election. "We believe it is important to communicate this to the public, as the replacement of PSUs impacts the quality of the data," emphasized Masduri. He noted that Poltracking Indonesia had submitted 2,000 survey data points from the Jakarta election to Persepi. The ethics board then requested the raw data from the dashboard, which Poltracking provided on Sunday (November 3, 2024). "The ethics board felt unable to verify Poltracking's data, even though we have clearly submitted all requested data and provided detailed explanations," Masduri added. Raw data has been sent. The ethics board only requested the raw data from the dashboard to compare it with the data that was submitted from the beginning. We have provided everything, he added. Poltracking stated that they were only asked to submit additional information if needed, which they fulfilled by October 31, 2024. "There was no specific request for the attachment of raw data from the dashboard," Masduri revealed. He emphasized that Poltracking's survey was entirely conducted using a digital application, unlike the manual paper questionnaire method used by LSI. "The electability results of the three candidates in the Jakarta Pilkada from Poltracking Indonesia cannot be equated with LSI, which compares printed questionnaires and raw data," he explained. He further mentioned that they do not understand the difference between the initial and final data referred to by the ethics board of Persepi. "We have complied with the ethics board's request regarding the raw data from the dashboard. There is no difference between the two sets of data," Masduri stated. He also highlighted that Poltracking has adhered to all Standard Operating Procedures (SOP) for surveys to ensure data quality. "We have already presented and explained this to the ethics board," he concluded.
