Barangay Dipusu is one of 36 barangays in the municipality of San Mariano, in the province of Isabela, in the Cagayan Valley region of the Philippines. According to the 2020 Census of Population and Housing, Barangay Dipusu had a population of 767 residents — the constituency that Ronald serves as Punong Barangay. Isabela is classified as a 1st by the Bureau of Local Government Finance.

Ronald Gumaru Zalun was elected to office in the most recent Barangay and Sangguniang Kabataan Elections (BSKE), which took place on October 30, 2023. Under Republic Act No. 12232, barangay officials elected in 2023 serve four-year terms, meaning the current mandate runs until 2026. The next BSKE is scheduled for Monday, November 2, 2026, per COMELEC Resolution No. 11191.

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.
