Abstract

Diarrhea that occurs in the digestive tract is a big problem for human intestinal health. This can be caused by the activity of pathogenic bacteria in the form of Vibrio cholera and Shigella dysinteriae. In this study, kombucha has been shown to have pharmacological activity in vitro in inhibiting the growth of Vibrio cholera and Shigella dysinteriae bacteria at all sugar concentrations. The purpose of this study was to determine the in vitro pharmacological activity of the butterfly pea flower kombucha in inhibiting the growth of the two test bacteria consisting of a sugar concentration of 20%, 30% and 40%. The method for testing the inhibition of both bacterial growth tests is disc diffusion. One way ANOVA and post hoc analysis are one of the quantitative test methods used in this study of the average diameter of the inhibition zone of teal flower kombucha from various sugar concentrations. The results of this study have proven based on a one-way ANOVA with each P value> 0.05 and then continued through post hoc analysis concluded that the telang flower kombucha at a concentration of 40% is the best treatment in inhibiting the growth of both test bacteria where the concentration is significantly different from sugar concentration 20% and 30%.

Abstract

Ferns or Pteridophyta are lower plants from the Cryptogamae division, which can be distinguished between roots, leaves, and stems. Ferns have great ecological importance, namely as understory plants that contribute to the long-term sustainability of forest ecosystems by mixing soil litter, as ground cover vegetation, as producers in the food chain, and as one of the pioneer plants in the succession of forest ecosystems. This study aims to determine the species, diversity index, and distribution pattern of ferns based on different vegetation in the Forest Area of Bukum Village, Sibolangit District, North Sumatra. The method used in this research is an exploratory survey method with a purposive sampling technique. The results of this study were 39 species found in the Forest Area of Bukum Village, 21 species in the watershed vegetation, 16 species in the Coffee Garden vegetation, and 14 species in the Primary Forest vegetation. The diversity index in the watershed vegetation is 2.32, the coffee plantation is 2.02, and the primary forest is 1.86. Based on the results of the diversity index, it shows that the diversity of ferns in the Forest area of Bukum Village is classified as moderate so the community is said to be stable. The Morisita index on the river flow vegetation is 1.43, the coffee garden vegetation is 2.13, and the primary forest vegetation is 2.05. The results of the Morisita index from each vegetation indicate that the distribution pattern of ferns in the Forest Area of Bukum Village is grouped because the environmental conditions required by ferns are not uniform.

Abstract

Soil-Transmitted Helminths (STH) are a type of intestinal worm that infects humans through soil contaminated with parasitic worms such as roundworms (Ascaris lumbricoides), whipworms (Trichuris trichiura), and hookworms (Ancylostoma duodenale and Necator americanus). STH infections have detrimental effects on children, which can be worrisome for their survival as well as their mental and physical development. Soil is one of the intermediaries for helminthiasis infection because surface soil is a place where worm eggs can survive for a long time. Feces from people with helminthiasis are an important source of soil contamination. This study is an analytical observational study with a cross-sectional design and purposive sampling technique with 50 elementary school-aged children in Gampong Jawa, Kuta Raja District, Banda Aceh City. Examination of the incidence of worms in children is done by examining feces (Kato-Katz method). The examination of soil samples using the floatation method. The results of the soil examination in this study showed that the soil in the children's yard was polluted by STH eggs by 26% and the soil that was not polluted by STH eggs by 74%. The highest STH contamination was Ascaris lumbricoides eggs at 43.5%. The results of fecal examination in children showed that as many as 10 people (20%) were infected with STH and 40 people (80%) were not infected with STH. Based on the Chi Square statistical test, a p-value of 0.002 was obtained, indicating that there is a significant relationship between soil pollution in the yard by STH and helminthiasis infection in children. This could be caused by factors such as poor personal hygiene and environmental sanitation.

Abstract

The background of this research is the lack of innovative digital technology-based learning media. There are not many digital interactive modules that have been developed to support learning. The limited availability of digital interactive modules can limit the use of technology in learning and hinder the achievement of learning goals in the era of Industrial Revolution 4.0. For this reason, it is necessary to develop digital-based interactive modules that provide opportunities for students to discover for themselves the concepts they are studying. Learners become more active and independently build knowledge. Research and development used the Borg and Gall model, which consists of product development, product validation, design revision, testing, and product revision. The research instrument consisted of a module validation questionnaire (content and media) and a response questionnaire. Module validation involves lectures at Teuku Umar University who are experts in their fields as content and media expert. The experts validation results obtained a combined score of 87.5%, indicating that the module can be used without repair. The product field test was carried out in the odd semester of the 2023–2024 academic year with 60 students at SMP Negeri 1 Aceh Barat. Field test results showed that 91% of students gave positive responses to the module. The development of digital-based interactive problem-based learning modules meets the requirements, can be used to facilitate active, creative learning, leads to the development of students' skills independently, and is relevant to technological developments.

Abstract

Pliek u, also known as patarana, is a traditional coconut oil produced by the people of Aceh, especially in Dayah Bubue Village, Pidie. The fermented oil from pliek u is often used by the villagers to be applied to itchy skin or wounds. It is necessary to isolate and identify the characteristics of isolates from pliek u and test isolates against carbohydrate fermentation in order to know the potential of pliek u isolates which are often used as seasonings for Acehnese cuisine. The purpose of this study was to identify the characteristics of fungal colonies found in the process of making pliek u, examine the physical factors of the substrate on fungal growth, and examine the results of carbohydrate fermentation tests. Research procedures: sampling at the research site in Dayah Bubue Village, Pidie, the process of isolating fungi from pliek u, culture purification, identification, and carbohydrate fermentation tests. The results of the research at the initial stage of fermentation found Soradia sp. and Curvularia sp., the final stage of fermentation found Soradia sp. and Microascus sp., pliek u stage found Mucor sp. Fungal characters in general large colonies, irregular shapes, round colonies, flat elevations, and notched margins. Changes in temperature and pH greatly affect the presence of pliek u. The five fungal isolates reacted positively to glucose and sucrose fermentation, but did not react positively to the lactose test.
