Abstract

The purpose of this research is to describe the knowledge of farmers about the seed of hybrid rice Mapan P-05, to analyze the conformance of performance and importance level, and to analyze farmers’ satisfaction to hybrid rice seeds of Mapan P-05. Sampling method used is census, where all the population members are farmers who use the seed of Mapan P-05. Methods of data analysis use descriptive analysis and quantitative analysis, which are IPA (Importance Performance Analysis) and CSI (Customer Satisfaction Index). The results found that the conformance level of performance and importance of hybrid rice seed Mapan P-05 is 80.2%; while the level of overall satisfaction is 62.06%. From the CSI, the attributes which should be considered by producers are the price, the seeds productivity, the seeds availability and the harvest age. Mapan P-05

Abstract

Microplastic pollution in rivers can harm ecosystems and water quality. This study aims to assess water quality and the ecological risk of microplastics in 15 locations in the North Coastal Area of Situbondo, which include rivers and estuaries. Water samples were analyzed based on water quality parameters, such as pH, TDS, ammonia, salinity, turbidity, DO, and BOD. Microplastics were identified using binocular microscopes and FTIR, with characteristics (size, shape, color) recorded. The Water Pollution Index (IP) showed a mild level of pollution with values ranging from 1.322 to 3.897, where IP values 1-3 are considered "mildly polluted." Ecological risk analysis using the Pollution Load Index (PLI), Polymer Hazard Index (PHI), and Potential Ecological Risk Index (PERI) showed that industrial and residential areas had a higher risk of pollution. A significant correlation was found between microplastic color and water quality parameters based on CCA analysis. The results of this study indicate that despite moderate water quality, microplastics pose significant ecological risks, especially in areas with high human activity, emphasizing the need for better environmental management
