Abstract

Background: Previous studies have shown that 3.6% of male adolescents in Indonesia have engaged in sexual intercourse, with permissive neglectful parenting identified as a significant contributing factor. Many children in Indonesia grow up without adequate parental care, leading to the establishment of nonprofit social organizations such as SOS Children's Village Semarang. This study aims to identify the factors contributing to risky sexual behavior among foster care adolescents at SOS Children's Village Semarang using the framework of social cognitive theory.Method: This study employed a mixed-methods approach with a sequential explanatory design. Quantitative data were collected through questionnaires, followed by qualitative data collection through observations and in-depth interviews. Binary logistic regression was used to analyze the quantitative data, while content analysis was used to analyze the qualitative data.Result: This study found that personal factors, including knowledge, attitudes, and expectations, along with environmental factors such as social norms and peer group influence, significantly contribute to risky sexual behavior among foster care adolescents. These findings emphasize the need for comprehensive interventions involving foster parents, orphanage staff, and peers to improve adolescents' understanding of sexual risks, promote positive attitudes toward sexuality, and strengthen their ability to resist negative peer pressures.

Abstract

Anisakis spp. are marine nematodes known to cause anisakiasis, a zoonotic disease transmitted through fish consumption with diverse clinical manifestations. In Indonesia, a country with extensive marine biodiversity and high fish consumption, data on anisakiasis remain limited. This study aimed to characterize the Anisakis spp. from the most significant commercial fish market in Semarang, Indonesia. A total of 17 Rastrelliger sp. were sampled. PCR amplification targeting the mitochondrial COX2 gene was used to identify the species of Anisakis spp. molecularly. Phylogenetic relationships, nucleotide diversity, and neutrality indices were assessed. The haplotype structures were visualized using the Haplotype Network. Subsequently, 7 of 17 (41.17%)  Rastrelliger sp. samples were infected with A. typica. Molecular analysis revealed two species, A. typica and H. amoyense, with high haplotype diversity (1.00±0.016, diversity±SD). Phylogenetic analysis revealed two major clades: A. typica (Semarang and Southern Makassar) and H. amoyense (Semarang, China, and Bangladesh), with both species indicating high genetic connectivity. Neutrality indices suggested purifying selection and population expansion for both species (dN-dS = -5.017). These findings highlight the genetic variability and zoonotic potential of Anisakis spp. in the commercial fish market, emphasizing the need for surveillance of fish-borne parasitic infections in Indonesia.

Abstract

Malaria remains a public health burden in tropical coastal regions, where complex environmental conditions support vector populations and increase transmission risk, particularly among vulnerable groups. Understanding the environmental characteristics of Anopheles spp. breeding habitats is essential for explaining vector distribution and informing control strategies. This study analyzed the environmental characteristics of potential Anopheles spp. breeding habitats in the coastal areas of Gaura Village. An observational descriptive survey with a cross-sectional approach was conducted using purposive spatial sampling across two survey rounds, measuring physical, chemical, and biological variables. A total of 12 breeding sites were identified, with confirmed vectors including Anopheles sundaicus (Rodenwaldt), An. subpictus Grassi, and An. barbirostris van der Wulp. Larval densities peaked in confined anthropogenic microhabitats, particularly buffalo wallows (3.5 larvae/dip) and footprints (3.1 larvae/dip). The habitats exhibited wide physicochemical variability (temperature 29.0–39.4°C; pH 7.3–9.2; salinity 0–20‰). Principal component analysis (PCA) explained 61.3% of total variation, distinguishing habitats along two gradients: PC1 (34.3%), driven by structural area, dissolved oxygen, and light intensity; and PC2 (27.0%), driven by pH and salinity. All highly productive habitats were located within 512 meters of residential areas, placing communities within the active flight range of vectors. These findings indicate that malaria transmission risk in coastal Gaura Village is driven by environmentally diverse yet spatially clustered larval habitats, particularly small, human-proximal sites associated with livestock, highlighting the need for targeted larval source management.
