Abstract

Introduction: Dental caries is a significant global health concern. Factors such as socioeconomic status, diet, oral hygiene, and access to dental care influence its prevalence. Limited information exists on dental health in remote sea-floating villages. This study aimed to analyze the correlation between demographic and environmental factors and dental caries prevalence in a sea-floating community. Methods: This cross-sectional study was conducted in Malahing Village, a sea-floating village located adjacent to the Makassar Strait, 4 km east of Bontang city. Seventy-two respondents aged 5–59 years were examined for the DMFT index, while intrinsic factors (demographic and dental health behaviors) and extrinsic factors (environmental and dental health services) were collected via questionnaires. Data were analyzed using descriptive univariate analysis to determine variable characteristics and Spearman’s correlation analysis. Results: Dental caries prevalence was 98.61%, with a DMFT index of 10.01. Age (r=0.564, p=0.001), education (r=0.370, p=0.002), and occupation (r=0.273, p=0.020) showed strong, moderate, and weak positive correlations, respectively. Rainwater exposure (r=-0.353, p=0.003) showed a moderate negative correlation. Sex, dental health behaviors, water source, and dental visits were not significantly correlated with caries prevalence. Adults showed highest prevalence (66.67%) but low DMFT index (1.00). Government employees had high DMFT scores (4.61). Twice-daily brushing was uncommon (66.67%) among individuals with high DMFT scores (6.15). Patients who never visited a dentist (44.44%) showed high DMFT scores (8.33). Conclusions: In this underserved coastal community, demographic disadvantages and environmental exposures, particularly water sources, combined with limited dental care contribute to an elevated caries burden compared to the national and international levels. Despite complex associations with environmental factors, rainwater exposure showed negative correlation with caries prevalence, highlighting measurement challenges. The high proportion of patients never visited a dentist, low oral health awareness, and nonstandard water management highlight critical service gaps.

Abstract

A module is an educational material or learning tool that includes teaching materials, methods, and assessments that are developed in a systematic and structured manner to achieve expected competency goals. The aim of this study is to develop a valid, practical and effective mangrove module based on ethnoscience on biodiversity. The type of research is R&D which refers to the ADDIE method developed by Mayfield. Data collection techniques consist of expert verification, observations, tests, questionnaires, and interviews. The results of the study show that, this module was developed based on the manual previously used by SMA IT Darul Hikmah Bontang students to learn biology. The module validity result for the module is 99%, which is in the very valid category. The material validity result of the module was in the very reasonable category at 84.69%. The linguistic validity result of the module was 73.6% in the valid category. The results of the student survey regarding the practicality of the module were 88.65%, which fell into the very practical category. The effectiveness module in improving student’s critical thinking ability and environmental awareness have n-gain values ​​are 0.55 and 0.44. It can be concluded that the development of the ethnoscience-based mangrove module in the intermediate category has been effectively used to improve the critical thinking skills of the students of SMA IT Darul Hikmah Bontang.

Abstract

Gendarussa (Justicia gendarussa) is a herbaceous plant with a height of 1-1.5 m. Its stem and leaves extract show antimicrobial and antioxidant activities and have potent cytotoxic activity on the human cancer cell. Gendarussa has a better flavor than stem. Its aqueous extract shows higher extract than ethanol extract. The present study evaluated the preservative effect of aqueous extract of gendarussa leaves (GL) in prolonging the shelf life of wet noodles. The single-factor experiment (GL of 0, 50, 100, 150, and 200 g was extracted in hot water of 100 mL) arranged in a completely randomized design was applied in this research. Total bacterial and mold were observed as well as sensory hedonic characteristics during storage. Data were analyzed using SPSS ver.25. The microbial quality data were analyzed by the Kruskal-Wallis test followed by pair comparison with Bonferroni correction, while the sensory data analyzed by Friedman test continued by Wilcoxon Sign Rank Test. The results showed that the addition of GL aqueous extract (200 g in 100 mL hot water) could prolong the shelf life of wet noodles. The microbial quality of the wet noodle, which preserved at room temperature for 24 h still meet the Indonesian standard of wet noodle (SNI: 2987-2015) for total bacteria and 36 h for total molds. The wet noodles have log cfu/g of 5.35 and 1.58 for total bacterial and mold, respectively. The panelists preferred the color, aroma, texture, and taste of wet noodles produced with the GL aqueous extracts. The most preferred one was wet noodle with the addition of GL aqueous extract at a concentration of 200 g per 100 mL with the characteristic of greenish-white color, not scented with GL, chewy texture, and slightly flavored GL.
