Abstract

This study aims to analyze the impact of pier construction on seaweed farmers’ income and to identify the diversification of farmers’ income sources in Bandar Batauga Village, South Buton Regency. The study was conducted from January to February 2026 using a quantitative approach. The research location was selected purposively, while a sample of 101 seaweed farmers was chosen using simple random sampling based on the Slovin formula. Data were collected through observation, interviews using questionnaires, and a literature review. Data analysis included income analysis, changes in income, and a paired-sample t-test. The results showed that average seaweed production decreased from 3,057 kg/year to 3,013 kg/year, while average income decreased from Rp48,910,891/year to Rp48,213,861/year. Average total costs also decreased from Rp16,680,156/year to Rp14,487,406/year due to a reduction in the scale of cultivation. Nevertheless, farmers’ average total income increased from Rp33,399,052/year to Rp41,780,911/year, representing a change of Rp8,380,838.84/year. The results of the paired-sample t-test showed a significance value of 0.001 < 0.05, indicating a statistically significant difference in income before and after the construction of the pier. This increase in income does not entirely reflect an improvement in aquaculture conditions but is also influenced by the diversification of income sources. The number of farmers engaged in other businesses increased from 5 in 2021 to 34 in 2025, including fishing, construction, gardening, loading and unloading services, and driving. Thus, the construction of the pier increased farmers’ total income but also led to adjustments in the scale of cultivation and encouraged the diversification of income sources among coastal communities.
