Abstract

Water is a vital resource for coastal communities, which often have limited access to clean water. This study aimed to analyze and compare the quality of rainwater and borehole water as drinking water sources in Sayolo 3, Tanjung Village, South Sorong Regency. This study employed a quantitative descriptive approach. Water samples were collected directly from the sources and analyzed in a laboratory for 12 physical and inorganic chemical parameters. The results were compared with the quality standards stipulated in the Indonesian Minister of Health Regulation Number 2 of 2023. The findings indicate that rainwater meets all tested parameters, including pH, total dissolved solids (TDS), turbidity, iron (Fe), lead (Pb), manganese (Mn), nitrate, and hardness. In contrast, the borehole water contains iron (Fe) at a concentration of 0.309 mg/L, exceeding the maximum permissible limit of 0.2 mg/L, although its other parameters remain within the safe limits. It was concluded that rainwater is more suitable for direct use as a drinking water source in the study area, whereas borehole water requires additional treatment, specifically to reduce iron content, to ensure its safety for consumption.

Abstract

Length–weight relationships using the allometric model W=aLb are widely applied to describe growth patterns in aquatic organisms. This study analyzed the length-weight relationship of bigfin reef squid (Sepioteuthis lessoniana) in Kolaka Waters, Southeast Sulawesi. Samples were randomly collected from fishermen’s catches in Tanggetada District during July–December 2025, with measurements of total length, mantle length, and body weight. The results showed that the population size structure was dominated by medium to large sized individuals. The length–weight relationship yielded a growth coefficient b<3, indicating a negative allometric growth pattern, where length increases faster than body weight. Although the allometric model effectively describes general growth patterns, its application across the entire size range should be treated with caution due to potential bias, particularly at extreme sizes. These findings provide important biological information to support the sustainable management of S. lessoniana in Kolaka Water.
