Eighteen digits in, one honest answer out.

## Challenge

Residents of Kabupaten Gowa and Kota Makassar pay PBB-P2, the land and building tax, and each local government has its own online service for checking a bill. The 18-digit tax object number (NOP) printed on the SPPT sheet is the key to both, but nothing tells a resident which service to use, and the answers the services return are hard to read. A check can also fail quietly, which is the dangerous case: a resident who sees nothing may assume the tax is paid. The tool had to work for anyone with an NOP, never present an uncertain answer as paid, and be open to other software as well as people.

## Solution

One card, one field. The NOP is typed into a field that formats it as it goes and names the region from its first four digits, 73.06 for Gowa and 73.71 for Makassar, so the right service is chosen for the resident. A diagram beside it shows how to read the number on the SPPT. Every answer lands in one of four statuses, Belum lunas (unpaid, with principal, penalty and due date per tax year), Lunas (paid), Tidak ditemukan (not found) and Belum pasti (not certain), and the last is never shown as paid. The About page explains how a check works and its limits, the FAQ says plainly that the result is not proof of payment and that NOPs are not stored, and the Contact page sends billing questions to the two regional revenue offices.

## Technology

The same check is offered to developers and AI agents: a public REST API with an OpenAPI description, an MCP server with check_pbb_bill and parse_nop tools, a WebMCP tool in the page, and llms.txt and other agent files, all free and without an API key. Each device is limited to 12 checks a minute so the government services are not overloaded. [To confirm: framework and hosting.]

## Result

Cek PBB Gowa & Makassar is a free web app for checking PBB-P2 property tax bills in Kabupaten Gowa and Kota Makassar by NOP, with web development and UI/UX design by goodtogrid. [To confirm: goodtogrid's scope and the client behind pbb.manujujaya.com.] The NOP field formats the 18 digits as they are typed and names the region from the first four, 73.06 for Gowa and 73.71 for Makassar. Unpaid bills show principal, penalty and due date per tax year, the FAQ says plainly that a result is not proof of payment and that NOPs are not stored, and each device is limited to 12 checks a minute to protect the government services. It works out the region from the number, reads both regional services into four plain statuses, never calls an uncertain answer paid, and offers the same check to developers and agents through a public API and an MCP server.
