The southwestern coast of Aceh Province is among the areas vulnerable to heavy metal pollution originating from human activities, including mining, agriculture, and household waste. Chue snails (Faunus ater) are among the aquatic organisms that can be used as a bioindicator of water pollution. Therefore, this study aimed to evaluate the content of Lead (Pb), Cadmium (Cd) and Mercury (Hg) in F. ater snails originating from seven estuary areas in the southwestern coast area of Aceh Province. Analysis was also carried out to determine the environmental factors affecting metal accumulation and potential risks to public health. Sampling was performed in various areas, including the Jembatan Kembar River (Aceh Singkil), Trumon River (South Aceh), Kuala Lama Tuha (Southwest Aceh), Peunaga Cut Ujong River (Nagan Raya), Suak Ribe Puteh (West Aceh), Teunom River (Aceh Jaya), and Leupung River (Aceh Besar). This study used a laboratory analysis method with Atomic Absorption Spectrophotometry (AAS) instruments to measure metal concentrations in F. ater tissue. The results showed that all samples from seven areas were contaminated with Pb, Cd, and Hg at levels ranging from 0.691 - 1.575 mg/kg, 0.285 - 0.311 mg/kg, and 0.001 0.030 mg/kg, respectively. Pb and Cd content showed high heavy metal content, which exceeded the safe threshold according to the Food and Drug Administration (BPOM), Republic of Indonesia, with the greatest concentration found in the Southwest Aceh Regency. These results showed that the consumption of F. ater had the potential to endanger public health. Therefore, it is necessary to conduct outreach to the community to increase environmental awareness and food safety.Keywords:Heavy MetalBioaccumulationEstuaryBioindicatorsFaunus aterSDGs 13SDGs 14

Each tribe has a tradition of ethnobotanical plant utilization and management, one of which is the Tamiang tribe. The community realizes the potential of plant utilization, thus creating considerable economic opportunities for bioprospection. This study used the Participatory Rural Appraisal (PRA) method to collect data by actively involving the community. Semi-structured interview techniques were conducted to explore ethnobotanical information from the Tamiang tribe. From the results of the Slovin analysis, 600 respondents with an age range of 35 to 94 years were obtained. Snowball sampling was used to select respondents. Determination of Sub-district locations selected six Sub-districts from 12 Subdistricts by purposive sampling with the largest number of Tamiang Tribe. The results showed that there were 225 species from 74 families used by the Tamiang people in treating various diseases. The most commonly cured diseases are fever, diabetes, and hypertension. Tagetes erecta is the most widely recognized medicinal plant species with a relative citation frequency index of 1.00. At the same time, Andrographis elongata is the most frequently used medicinal plant by the local community with a use value index of 1.00. In addition, local people identified the leaf organ (60.89%) as the most commonly used part of the plant, while decoction (58.20%) was the most popular method of administering traditional medicine. Both species of Andrographis elongata and Moringa oleifera have the potential to treat diabetes and hypertension as seen from the highest ICS value as prospective plants in the utilization and management of medicinal plants, so they can be developed as raw materials for herbal medicine.

Shark is a cartilaginous fish that is widely hunted because it has high economic value. The waters of Aceh are directly adjacent to the Indian Ocean and the Malacca Strait making it a preferred habitat for pelagic fish, especially sharks. Information on shark species landed in the waters west and east of Aceh is very limited due to difficulties in identification and commonly used local names. This study aimed to determine the types of sharks landed in Banda Aceh, Meulaboh, Langsa, Southwest Aceh and Simeulu and to find out specifically what species of sharks are most often landed in Aceh waters. Primary data gathering consisted of four stages, namely sample collection, identification using identification books, molecular identification cytochrome oxidase subunit I (COI) and phylogenetic analysis. The results of the molecular analysis of 46 tissue samples from five locations identified 13 species of sharks, namely Carcharhinhus sorrah, Carcharhinhus amboinensis, Triaenodon obesus, Isurus oxyrinchus, Sphyrna zygaena, Sphyrna lewini, Loxodon macrorhinus, Hemipristis elongaria, Stagostoma fasciatum, Nebrius ferrugineus, Chilloscyllium punctatum, Isurus oxyrinchus, Alopias pelagicus, Alopias supercillosus and 1 species of rays, namely Rhynchobatus australiae. Phylogenetic tree reconstruction using the Neighbor Joining method of 610 basepairs consisting of two large clades separates the species Alopias pelagicus and Isurus oxyrichus with Carcharhinus sorrah, Sphyrna lewini, Loxodon macrorhinus and Rhyncobatus australiae with boostrap values of 87% and 64%. The haplotype diversity shown ranged from 0.667-0.889 while the nucleotide diversity ranged from 0.001-0.097. These values indicates high diversity because of the variance in the number of species found.Keywords:BarcodeCOISharks catchAlopias supercillosusSphyrna lewini

Dengue Hemorrhagic Fever (DHF) is a disease that currently has significant morbidity and mortality rates. In Indonesia, the trend of DHF cases has increased and decreased every year. This study aims to analyze the development of dengue cases by considering two indicators, namely dengue incidence rate and dengue case fatality rate (CFR) during the period 2012-2022, to know the pattern of dengue disease in Indonesia, and evaluate the government's target in handling dengue cases based on IR and CFR rates. The data used is secondary data obtained from the 2021 Indonesian Health Profile and the 2022 Dengue Fever Annual Report. IR and CFR data were analyzed using Microsoft Excel which will be interpreted in the form of graphs to illustrate the trends and patterns of DHF cases in Indonesia, IR maps in 2021 and 2022 were analyzed using ArcGIS software. Based on the results of the analysis, the development of dengue cases during the period 2012-2022 experienced a misalignment between the increasing trend of IR and CFR. The IR value experienced significant fluctuations from 37.3 per 100,000 population in 2012 to 52.07 per 100,000 population in 2022, while the CFR value during the period 2012-2022 tended to decrease from 0.90% (2012) to 0.86% (2022). This pattern reflects the complex dynamics of DHF epidemiology, where an increase in cases is not always followed by an increase in fatalities. The IR and CFR achievements for 2022 have not met the government's expectations, with only 16% of districts/cities having IR values â‰¤ 10/100,000, while the CFR value reached 0.86%, slightly above the set target of 0.7%.

Octopus cyanea is an ecologically and economically important cephalopod with wide larval dispersal influenced by ocean currents. However, geographic isolation among island clusters in northern Sumatra may restrict gene flow and shape population structure. This study investigated the genetic diversity and connectivity of O. cyanea from five populations (Aceh Island, Weh Island, Banyak Island, Simeulue Island, and Nias Island) using mitochondrial cytochrome c oxidase subunit I (COI) sequences. A total of 21 individuals were successfully amplified, yielding 651 bp fragments. Sequence analysis revealed 11 haplotypes across populations, with haplotype diversity (Hd) ranging from 0.285 in Banyak Island to 0.800 in Aceh Island, and nucleotide diversity (π) between 0.001 and 0.009. Pairwise genetic distances varied from 0.000 to 0.004, with the highest divergence observed between Simeulue Island and Nias Island (0.004), while Aceh Island and Weh Island showed no differentiation. AMOVA indicated that most genetic variation occurred within populations (68.74%), with an overall Fst of 0.315, suggesting low to moderate genetic structuring. The haplotype network demonstrated shared haplotypes among four populations, whereas Simeulue Island harbored unique haplotypes, indicating partial genetic isolation. These results highlight substantial genetic connectivity among O. cyanea populations in northern Sumatra, facilitated by larval dispersal via ocean currents, but also emphasize localized divergence in Simeulue Island. The findings provide critical baseline data for developing ecosystem-based fisheries management, supporting shared stock strategies while accounting for population-specific conservation needs.
