Abstract

Dengue Haemorrhagic Fever (DHF) is transmitted through the bite of Aedes aegypti, and the continuous use of chemical larvicides can harm the environment, so a safer natural alternative such as betel leaf (Piper betle L.) extract is needed. To determine the effectiveness of betel leaf extract as a natural larvicide against Aedes aegypti larvae mortality. A laboratory experiment with a post-test only control group design tested concentrations of 0.05%, 0.1%, and 0.5% plus a control, each with six replications over 24 hours, using 600 third-instar larvae. Data were analysed using one-way ANOVA, the Bonferroni test, and probit analysis for LC50/LC90. Mortality increased with concentration, namely 14.7% (0.05%), 56.7% (0.1%), and 91.3% (0.5%), with no mortality in the control group. ANOVA showed a significant difference (p = 0.00), and probit analysis produced LC50 = 0.142% and LC90 = 0.472%. Betel leaf extract is effective as a natural larvicide, with 0.5% the most effective concentration and recommended for community application, although further field trials are still needed to validate the optimal concentration.

Abstract

Formalin is a chemical substance prohibited for use as a food additive because it may pose serious health risks, yet wet noodles containing formalin are still found in several traditional markets in Palembang City according to reports from the Palembang Food and Drug Control Center (BBPOM). This study aimed to determine traders' knowledge regarding formalin content in wet noodles sold at traditional markets in Palembang City in 2026. This descriptive study used an observational approach involving all 45 wet noodle traders in Palembang City's traditional markets, selected through total sampling. Data on traders' knowledge were collected through questionnaire-based interviews, while formalin content was examined using a Rapid Test Kit. Data were analyzed univariately and presented as frequency distributions. Results showed that most traders (48.9%) had a moderate level of knowledge, followed by good (26.7%) and poor (24.4%) categories. Formalin testing revealed that 8 samples (17.8%) were positive and 37 samples (82.2%) were negative. Organoleptic testing showed that most samples had a non-pungent odor (88.9%), a pale-yellow color (68.9%), and a non-chewy texture (60%). In conclusion, although most traders possess a moderate level of knowledge, formalin was still detected in several samples, indicating that continuous education and regular food safety monitoring remain necessary.
