Abstract

Acute gastroenteritis (GEA) is gastrointestinal disease whose signs and symptomps are diarrhea, anorexia, vomiting, abdominal pain and fever. This condition is very common in children. Bronchopneumonia is a patchy inflammation of the lungs (exceeding one or two lobes) where exudate from white blood cells accumulates in the bronchi and bronchioles with spread to adjacent alveoli. Immunization can reduce the risk of the two diseases. This study will comprehensively discuss the relationship between incomplete immunization and the occurrence of ARI and bronchopneumonia in order to enable appropriate management. The method involves conducting a literature review by gathering literature from books and articles published in the last 10 years. We report a case of GEA along with bronchopneumonia in an infant aged 4 months 26 days with a history of incomplete immunization. Catch-up immunization should be carried out in all babies with a history of incomplete immunization to reduce the risk and severity of subsequent.

Abstract

Seruway is one of the sub-districts in Aceh Tamiang, which is located in the coastal area. This coastal area is dominated by mangrove species, where the mangrove area is used as a habitat for aquatic biota animals, one of which is gastropods. Gastropods are soft-bodied animals that have threaded shells. This research aims to determine the value of the species diversity index and distribution patterns of gastropods in Kupang Beach, Seruway District. This research is a type of quantitative descriptive research with sampling using a survey method. Sampling was taken using transects. Sampling was divided into 3 stations, namely the first station in the mangrove area, the second station in the beach area and the third station in the pond area. Each station consists of 4 transects measuring 50 meters, each transect has 4 plots measuring 10x10m. Samples that are obtained will be identified using an identification book. The research results showed that the number of gastropod species found was 17 species from 9 families with a total diversity index value at the research location, namely H'= 2.405, which is classified as medium. The distribution pattern of gastropods on Kupang Beach falls into two categories, namely the uniform category 59% and the undefined category 41%.

Abstract

Fruit bats (family Pteropodidae) pollinate around 300 species of tropical plants of high economic value over a wide range of areas. This large role does not match the status of their population, which continues to decline due to habitat loss, particularly in urban areas. The Sumatra Institute of Technology (ITERA) campus, which is currently under development, may result in habitat changes that may affect bats. These concerns have led to the need for research into bat diversity on the ITERA campus. The result could be utilised to monitor and develop the environmental management of the campus. The research was conducted from May to September 2023 in five different habitat types. Data were collected using 3 mistnets and 3 night repetition each habitat. The data were analysed using indices of diversity, evenness and species richness. The study recorded 143 individuals of 7 species. The highest number of species and diversity was observed in the sengon and rubber habitat (6 species). The lowest number of species and diversity was found in the botanical garden (2 species).

Abstract

Insufficient nutritional intake from the beginning of pregnancy until the first two years of life has a significant effect on the child's growth and development process, such as stunting. Stunting is the condition of a child having a length or height that is lower or less than his age and has a value < -2 standard deviation. Malnutrition in children can inhibit the formation of brain cells resulting in changes to the structure and function of the brain itself. This will then have an impact on the child's cognitive development. The research aims to determine the relationship between stunting and cognitive development in children aged 2-5 years. The sample used in this research was toddlers aged 2-5 years, totaling 38 children. The research design used was cross-sectional (cross sectional study). Data were analyzed using the Somers'D statistical test. The research results found a relationship between stunting and cognitive development in children aged 2-5 years. The conclusion is that children who experience stunting will cause their cognitive abilities to decline.
