Abstract

The distribution and abundance of fish are strongly influenced by several oceanographic parameters, one of which is chlorophyll-a. Chlorophyll-a is one of the oceanographic parameters that play an important role in primary productivity in the sea. The distribution of chlorophyll-a contained in phytoplankton can be used as a measure of fertility in water. With advances in geographic information systems or remote sensing, the distribution of chlorophyll-a can be used to estimate fish catchment areas. This study aims to look at the distribution of chlorophyll-a in Aceh waters both spatially and temporally to predict fishing locations. This study used satellite imagery combined with a Geographic Information System (GIS) to detect chlorophyll-a’s distribution. The results of satellite image processing show that the average monthly value of chlorophyll-a in Aceh waters ranges from 2.71 – 23.54 mg/m3, areas with high chlorophyll-a are generally located in the western waters of Aceh to the southwestern waters of Aceh, while areas with The lowest chlorophyll-a is generally in areas far from the coast (towards the open sea) with a range of 0.04 – 0.5 mg/m3 where the lowest average occurs in the east monsoon. However, in general, the potential locations for fishing grounds are more in the waters west of Aceh than in the waters north of Aceh, Aceh waters.Keywords:Chlorophyll-aSatellite imageFishing areaGeographic information SystemAceh Waters

Abstract

Soil-transmitted helminth (STH) infections remain a significant public health issue in developing countries, particularly among primary school children who are highly exposed to contaminated environments and often have inadequate personal hygiene practices. This study aimed to describe the presence of STH eggs in fecal samples of first- to third-grade students at SDN 23 Pasir Sebelah, located in Koto Tangah District, an area with historically high helminth infection rates. A descriptive cross-sectional design was used, involving total sampling of 124 students. Fecal specimens were examined microscopically using the direct smear method. Results showed that 6 students (6.9%) tested positive for STH eggs. The species identified included Ascaris lumbricoides (50%), Trichuris trichiura (40%), and hookworm (10%). Infections were more frequently found in male students and those aged 7–8 years. Most infected children demonstrated poor personal hygiene, particularly related to handwashing, nail cleanliness, and consistent use of footwear. In conclusion, the prevalence of STH infection among students at SDN 23 Pasir Sebelah was relatively low; however, inadequate personal hygiene remains a key contributing factor. Strengthening health education and promoting proper hygiene practices are essential to reduce the risk of STH transmission in school-aged children
