Abstract

This study aims to analyse the effect of income structure and population structure on animal protein consumption in Samarinda, Balikpapan, and Bontang, East Kalimantan, during 2020–2025. Secondary panel data (18 observations) were obtained from BPS and the East Kalimantan Office of Industry, Trade, Cooperatives, and SMEs. Income structure was measured by per capita income and the city minimum wage (UMK), population structure by the population aged 0–14, 15–59, and 60+ years, and animal protein consumption by beef and chicken meat consumption. Data were analysed using PLS-SEM (SmartPLS 4) with 5,000 bootstrap subsamples. The results show that income structure (β = 0.808; t = 6.440; p < 0.001) and population structure (β = 0.570; t = 4.252; p < 0.001) have positive and significant effects on animal protein consumption, with an R² of 0.828 and a Q²predict of 0.781. Food security policies should maintain purchasing power and anticipate population-driven demand.
