Abstract

Noise in classrooms can disrupt communication between teachers and students, potentially affecting learning outcomes. Previous research indicates that noise exceeding environmental health standards may contribute to communication difficulties during lessons. This study aimed to analyze the effect of classroom noise and communication disruptions on students’ learning achievement. An observational analytic study with a cross-sectional design was conducted among 4th and 6th grade students at one of the elementary schools in South Surabaya. Noise levels were measured in the classrooms, and students were assessed for communication disruptions and learning achievement. Logistic regression was used for data analysis. All classrooms exceeded the environmental health noise threshold of 55 dB(A), with an average level of 67.45 dB(A). Noise was significantly associated with communication disruptions (OR = 5.118; p = 0.012). Classroom noise increased the risk of communication disruptions but did not directly affect students’ learning achievement. It is recommended to install soundproof partitions and double-glazed windows to reduce noise. Future studies should investigate the interaction between teaching methods and student achievement.

Abstract

Avocado leaves contain various compounds that are proven to cause death in Aedes aegypti larvae. In its use has limitations, namely the nature of the extract tends to cause turbidity in water, thus inhibiting the survival of Aedes aegypti larvae. In contrast to Aedes aegypti larvae, Culex sp larvae can live and develop well in dirty water. This study aims to assess the potential of avocado (Persea americana) leaf juice as a biolarvicide of Culex sp. The treatment consisted of five groups of avocado leaf juice concentrations, namely 0% (negative control), 2.5%, 5%, 7.5%, and 10%. Each using 20 Culex quenquefasciatus instar III larvae with replication 6 times. Mortality data of Culex sp larvae exposed to avocado leaf juice for 24 hours were analyzed using Anova test, Bonferroni test, and Probit test. The results showed that the mortality rate of larvae was 12,5%, 25%, 72,5%, and 92,5%, respectively. The Anova test showed that there was a significant difference between the concentrations of avocado leaf juice (p=0.000), the Bonferroni test showed that only the negative control (0%) and the 2.5% concentration, as well as the 2.5% and 5% concentrations, were not significantly different. The LC50 value obtained is 2.338%. It was concluded that avocado leaf juice has the potential as a biolarvicide against Culex sp.

Abstract

Aedes aegypti is a species of mosquito that acts as a vector for the dengue virus. Currently, control of this viral vector has been carried out using synthetic insecticides. However, continued use can lead to the emergence of resistance, necessitating efforts to address this issue. One possible approach is to use natural insecticides derived from plants. One plant considered suitable as a natural insecticide is the extract of crystal guava leaves (Psidium guajava Linn) because it contains bioactive compounds such as flavonoids, tannins, alkaloids, and saponins. The purpose of this study was to determine the effectiveness of using crystal guava leaf extract as a spray insecticide against Aedes aegypti mosquitoes. This study used an experimental method with a Control Group Post-Test Design. Ethanol extract of crystal guava leaves (Psidium guajava Linn) was prepared in several concentrations: 22.5%, 45%, and 90%. The spray was then observed on Aedes aegypti mosquitoes for 3, 6, and 24 hours. The concentration was then determined to determine the mosquito-killing power. Analysis was then performed using SPSS to determine the LC50 and LT50 values.

Abstract

This research is based on the need for environmentally friendly alternatives to chemical insecticides. To determine the potential of ethanol extract of jasmine flowers (Jasminum sambac L.) as a repellent against houseflies (Musca domestica). The study employed a post-test only control group design with ethanol extract concentrations of 15%, 20%, and 25%, along with a positive control (Venox fly repellent spray) and a negative control (distilled water). The effectiveness was assessed by counting the number of flies that landed and were repelled. Data were analyzed using probit regression to determine the ED₅₀ and ED₉₉ values. Higher extract concentrations resulted in stronger repellent effects. A 15% concentration produced a repellency rate of 34.37%, 20% achieved 51.64%, and 25% reached 80.61%. The ED₅₀ was found at 16.494%, and the ED₉₉ at 38.222%. Ethanol extract of jasmine flowers has the potential to serve as an effective natural bioinsecticide for controlling houseflies.

Abstract

Worm infestations are a significant public health issue, primarily caused by Soil Transmitted Helminths (STH). One of the most common parasites affecting poultry is Ascaridia galli, which causes ascariasis and results in weight loss and impaired growth in affected birds. This study aims to evaluate the anthelmintic effects of a combined ethanol extract of papaya leaf and soursop leaf on the mortality of Ascaridia galli in vitro. We employed a quantitative, experimental laboratory approach using a Posttest-Only Group Design to determine the efficacy of the combined extracts as a treatment for Ascaridia galli. Each treatment group consisted of 7 worms, and the experiment was repeated 6 times with exposure times of 2, 4, and 6 hours. The data collected were analyzed using probit regression to assess the potential of the combined ethanol extracts of papaya and soursop leaves on the mortality rates of Ascaridia galli. The effectiveness of the extracts was evaluated based on the LC50 (lethal concentration for 50% of worms) and LC50 (lethal time for 50% of worms). The study found that the LC50 values were 47.614% at 2 hours, 20.549% at 4 hours, and 8.091% at 6 hours, while the LC50 values were 4.006 hours for 25% mortality and 1.536 hours for 50% mortality. These results indicate that the combined ethanol extracts of papaya leaf (Carica papaya L.) and soursop leaf (Annona muricata L.) show potential as an effective anthelmintic treatment against Ascaridia galli, with mortality rates increasing with longer exposure times and higher concentrations.
