Roger Mabaquioa Mucho

As Punong Barangay of Barangay Old Poblacion, Roger Mabaquioa Mucho presides over the Sangguniang Barangay of the barangay in Buenavista, Guimaras, serving the 2023 - 2026 term. The Punong Barangay is a nationally recognised local government position under the Local Government Code of 1991 (Republic Act No. 7160).

Under the Local Government Code of 1991, the Punong Barangay leads the Sangguniang Barangay, signs ordinances and resolutions, represents the barangay in transactions with other government units, administers the barangay budget and appropriations, and oversees the Lupong Tagapamayapa that handles amicable settlement of disputes at the barangay level. The office is the most directly accountable elected position in the Philippine government.

Barangay Old Poblacion is one of 36 barangays in the municipality of Buenavista, in the province of Guimaras, in the Western Visayas region of the Philippines. According to the 2020 Census of Population and Housing, Barangay Old Poblacion had a population of 1,226 residents — the constituency that Roger serves as Punong Barangay. Guimaras is classified as a 4th by the Bureau of Local Government Finance.

Barangay officials in the Philippines are elected during the synchronised Barangay and Sangguniang Kabataan Elections (BSKE). Roger currently holds office under the mandate established by the October 30, 2023 BSKE. The next BSKE, at which this position will again be contested, is scheduled for Monday, November 2, 2026.

A Philippine barangay's Sangguniang Barangay is composed of one Punong Barangay, seven Sangguniang Barangay Members (kagawads), a Sangguniang Kabataan (SK) Chairperson representing the youth sector, a Barangay Secretary, and a Barangay Treasurer. Together, these officials administer the smallest unit of Philippine local government and deliver frontline services — from barangay clearance issuance to peace and order, from public health assistance to the barangay's share of the Internal Revenue Allotment.
