DIY Regional Government Lodges Protest with BPS over Decile Data

The DIY regional government has lodged a protest with the Central Statistics Agency (BPS) regarding the data on welfare grouping, or deciles, which has undergone significant changes. The decile grouping refers to the National Socio-Economic Single Data (DTSEN). Through this system, Indonesian citizens are grouped into 10 categories or deciles. Each decile covers approximately 10 percent of the population, with decile 1 being the group with the lowest level of welfare and decile 10 being the group with the highest level of welfare. The determination of deciles does not only consider family income. A number of other indicators are also taken into account, ranging from housing conditions, education, employment of family members, electricity usage, to asset ownership.

DIY Regional Secretary Ni Made Dwipanti Indrayanti revealed that many residents have protested because their decile status changed from low to high. According to her, this makes the poverty rate appear to have decreased. “Many have protested about the deciles. I have also protested to Bu Endang about this. How could it be like that? Is it perhaps to reduce the burden, so everything was raised, so to speak,” Made said when met at the Kepatihan complex, Yogyakarta City, on Wednesday (19/8/2026). “The deciles that are our responsibility now are deciles 1 to 5, meaning those below the poverty line. Those in deciles 6 to 10 are considered able to survive and be independent,” she added.

Made stated that she has attempted to seek clarification on this matter from the Acting Head of BPS DIY, Endang Tri Wahyuningsih. “So this is what I asked for clarification about with Bu Endang, the Acting Head of BPS. Why is it like this, what is the basis? We have not had the chance to meet yet,” she said.

Meanwhile, the Head of the DIY Social Affairs Agency, Suyarno, said the changes in decile data were due to the many indicators used that do not correspond to the actual conditions of the community. “The authority to determine deciles lies with the central BPS. The DTSEN data, which is a combination of several data sources with different indicators, certainly requires adjustments,” Suyarno said when contacted on Thursday (20/8). “Currently, in addition to DTKS, Regsoseg, and P3KE data, there is also BKKBN data and the results of the economic census that have an impact on decile changes that do not match real conditions in the field. For example, there are those whose decile rose because it was adjusted with BKKBN data,” he continued.

Suyarno said residents who find their decile status has changed and does not match reality can submit a request for correction. The method is to visit the SIKS-NG (Next Generation Social Welfare Information System) operator in each village. “It is still very possible to submit a decile change. Some residents have already submitted changes to their decile. They simply report and bring their population identity card,” he said. “They can also submit a change through the cek bansos application, which can be done independently through this mechanism. It can be downloaded from the Play Store. We cannot confirm the deadline because the authority lies with the central BPS,” Suyarno added.

When asked for confirmation separately, BPS DIY stated that it would hold a press conference with the Acting Head of BPS DIY at a time yet to be determined.

On Thursday (20/8) afternoon, the DIY regional government and BPS DIY met behind closed doors at the office of the DIY Regional Secretary, Kepatihan Complex, Yogyakarta City. Regional Secretary Ni Made Dwi Panti Indrayanti said the meeting discussed the determination of deciles, which she said is the authority of the central government. As a data user, according to Made, the DIY regional government needs to understand the criteria and basis for the grouping so that the data used in poverty handling can be fully understood and aligned with the conditions of the community in the region. “The data comes from the central government, not something we determine. What we need to discuss is the criteria and how far they go. How they compile and classify it is what we need to ask BPS,” Made explained through a written statement received by detikJogja on Thursday (20/8) evening.

Made said the DIY regional government actually also has data developed through collaboration with district and city governments. This data is integrated in the One Poverty Data system and provides a detailed picture of community conditions. “So actually with that one data system, we can monitor. It is already very detailed in terms of what category of poverty, what assistance they receive, and what type. It is all visible there,” she said. According to Made, the meeting was also aimed at aligning, not comparing, the data held by the regional government with the central government’s data. “We do not intend to compare data. But to align data,” Made stressed.

Meanwhile, the Acting Head of BPS DIY, Endang Tri Wahyuningsih, explained that DTSEN is a database that integrates social and economic information to support more targeted government policies. Endang said DTSEN was built through the integration of various data sources such as Regsosek, DTKS, and P3KE, enriched with data from PLN, BPJS Kesehatan, and others. It is then matched with population administration data. In DTSEN, family data is collected based on relative welfare levels, then ranked and divided into 10 groups called deciles. Decile 1 covers 10 percent of families with the lowest relative welfare level, while Decile 10 represents 10 percent of families with the highest relative welfare level. “The determination of decile position considers 41 input variables grouped into Family Identity information, Housing information (condition and quality of dwelling), Asset Ownership, and Family Member information (education, employment, income, disability status),” she said.
