Abstract

Daerah pesisir laut kerap kali dijadikan sebagai tempat pembuangan sampah anorganik dari berbagai aktivitas manusia seperti kegiatan tempat wisata, tempat pelelangan ikan dan kegiatan industri yang sangat berpotensi sebagai zat pencemar air laut dalam bentuk mikroplastik akibat proses degradasi atau fragmentasi sampah plastik. Penelitian ini bertujuan untuk menganilisis korelasi kualitas air terhadap kelimpahan mikroplastik di pesisir laut Galesong Utara kabupaten Takalar pada kondisi surut. Penelitian ini dilakukan melalui pendekatan kuantitatif (bersifat analisis) dengan menggunakan metode observasi lapangan di lima stasiun dengan jarak titik sampling (air laut yakni 0-100 m dan 100-200 m dari bibir pantai yakni di area kawasan pemukiman padat penduduk ST1), area wisata (ST2), area industri (ST3), kawasan pemukiman kurang penduduk (ST4) dan area pasar (tempat pelelngan ikan) (5). Hasil penelitian menunjukkan adanya korelasi antara parameter kualitas air yakni suhu, ph, DO, TSS, kekeruhan dan salinitas terhadap kelimpahan mikroplastik di pesisir laut galesong utara (nilai sig. < 0,05) dengan tingkat korelasi yang sangat kuat untuk parameter suhu dan DO, tingkat korelasi yang kuat untuk parameter TSS, kekeruhan dan salinitas serta tingkat korelasi yang cukup untuk parameter ph terhadap kelimpahan mikroplastik.

Abstract

The use of detergent from laundry businesses which is thrown directly into water bodies causes pollution of the aquatic environment because of its large accumulation and the nature of the compound content which is difficult to break down by decomposing microorganisms in water bodies. This research aims to determine the most optimal mixing ratio for the mortality time of the test insects. This research uses a laboratory pre-experiment method with research variables between liquid laundry waste containing LAS compounds and citronella compounds from lemongrass extract, namely 2:1; 4:1 ; 6:1 ; and 8:1. This research used test insects in the form of black ants that disturb orchid plants with 3 repetitions of insecticide testing. In this study, the results of the analysis of laundry waste LAS levels were 8 mg/L with a citronella concentration of 37.62%. The test results showed that the most optimal mixing ratio for black ant test insect mortality was 2:1 with a black ant mortality time of 28 seconds.

Abstract

Background: Flood-prone areas present significant public health challenges, particularly in urbanized regions where inadequate drainage systems and water stagnation create ideal breeding grounds for disease vectors such as mosquitoes. This study investigates the relationship between flood risks and mosquito habitat proliferation in Gowa, South Sulawesi, Indonesia. Methods: By combining a comprehensive field survey with Geographic Information System (GIS) spatial mapping, the study aimed to identify environmental and infrastructural factors contributing to mosquito breeding, particularly Aedes aegypti, the primary vector for dengue and Zika virus. Findings: The results revealed that areas with poorly managed drainage systems and stagnant water were high-risk zones for mosquito breeding, correlating with increased mosquito densities and higher disease transmission potential. The study also found that rapid urbanization, combined with insufficient waste management, further exacerbates the risk by providing numerous breeding sites for mosquitoes. The findings support global observations that similar challenges in other tropical regions, including Brazil and Indonesia, contribute to the spread of mosquito-borne diseases. Conclusion: This research highlights the critical role of environmental infrastructure in controlling vector-borne diseases and emphasizes the need for improved urban planning, integrated vector control strategies—including better drainage infrastructure, community education, and regular sanitation practices—to reduce mosquito breeding sites. Overall, it provides valuable insights for local authorities and public health organizations, offering a framework for targeted interventions in flood-prone areas. Novelty/Originality of this article: The novelty of this study lies in combining GIS spatial mapping with field surveys to directly link flood-prone urban infrastructure and environmental factors to mosquito habitat proliferation, providing a framework for targeted, location-specific public health interventions.
