Abstract

Although agricultural insurance plays a vital role in minimizing the potential risk of yield loss, the adoption rate among farmers in Indonesia remains low. Using cross-sectional data from the Indonesian rice farmers’ survey, this study investigates how participation in a farmer group affects the decision to adopt agricultural insurance. A recursive bivariate probit model was employed to estimate the participation’s effects on agricultural insurance adoption. The finding indicates that farmer group participation positively and significantly affects the adoption. Regarding the control variables, farmers’ experience and education drive the adoption. In contrast, age shows a negative correlation. Meanwhile, the determinants of farmer group participation are gender, access to credit, and social activity involvement. Likewise, age also negatively and significantly affects the probability of farmer group participation. These findings highlight the essential role of farmer group participation in agricultural insurance adoption. Therefore, we suggest promoting membership sign-ups among smallholder farmers Keywords: agriculture insurance, farmers group, recursive bivariate probit model, rice farmers

Abstract

The Petung River supports domestic, agricultural, and economic activities in Pasuruan City but is subject to increasing anthropogenic pressures. This study aims to assess the river water quality status and formulate water pollution control strategies. Water quality was evaluated using the Pollution Index based on laboratory measurements conducted in April and June 2025. A SWOT analysis was performed by identifying internal and external factors through field observations and key informant interviews, followed by weighting and ranking to determine strategic priorities. The results indicate that the Petung River is predominantly classified as lightly polluted, with Pollution Index values ranging from 2.48 to 5.06, while one monitoring point in June 2025 reached a moderate pollution status. Although pH (6.75–7.80) and nitrate (1.15–3.40 mg/L) complied with Class II standards, total suspended solids, biological oxygen demand (6.49–16.01 mg/L), chemical oxygen demand, and total phosphate (0.27–3.03 mg/L) exceeded regulatory thresholds. The priority strategy is the establishment of communal wastewater treatment systems, supported by improved coordination, institutional capacity, community-based programs, and strengthened monitoring.
