Alginate impression materials in dentistry are used to form details of the oral cavity organs. The alginate content in the impression material functions to form a gel. One source of alginate is algae. Objective: This study aims to determine the recovery elasticity and setting time of alginate impression materials made from red algae K. alvarezii. Methods: The sodium alginate in the composition of this alginate impression material was extracted from red algae K. alvarezii. The alginate impression material was tested for setting time and recovery elasticity and compared with commercial impression material (Hygedent®). Results: The elastic recovery of red algae sodium alginate impression materials was 97.43% which was not significantly different from the commercial impression materials (98.42%). These results showed that this alginate impression material has the same properties as commercial impression materials. In the setting time test, the the red algal alginate impression material was much longer than the commercial impression material, 1.39 m and 3.30 m respectively. Conclusion: It was concluded that the alginate impression material from the red algae K. alvarezii had a long setting time. At the same time, the recovery of elasticity did not differ from that of commercially available alginate impression materials.

Background: Alginate is an impression material that is widely used in dentistry. Alginate can actually also be obtained from natural materials such as red seaweed. The impression procedure causes the impression material to come into contact with oral tissues including the gingiva. Ideally, the materials used must also meet requirements such as low toxicity or non-toxicity so that tissue damage does not occur. This study aims to analyze the cytotoxicity of alginate impression materials from red seaweed extract in gingival fibroblast cell. Method: This experimental laboratory design using post-test only control group design. The research groups consisted of: sodium alginate extract group, red seaweed extract-based alginate impression material, positive control and negative control. Cytotoxicity was tested on gingival fibroblast cell cultures and the effect was analyzed using the MTT assay. Exposure to gingival fibroblast cell cultures was differentiated in three time durations: 5 minutes, 10 minutes and 15 minutes. Each time duration was repeated three times. MTT-formazan production is a method used to measure cell viability (living cells). The data obtained were statistically analyzed using two-way ANOVA test and Tukey HSD post hoc test. Result: There was no significant difference in the average cell viability between the red seaweed extract-based alginate impression material group and the negative control group at an exposure duration of 5 minutes, which was more than 90%. Conclusion: The red seaweed extract-based alginate impression material has no toxic effect on gingival fibroblast cells at 5 minutes exposure.

Stunting in toddlers is related to growth and development disorders. One important factor in preventing stunting is the implementation of Clean and Healthy Living Behaviour (CHLB). CHLB plays a role in improving the nutritional and health status of children, as well as preventing various diseases that can contribute to stunting. The role of cadres is very important because cadres are responsible for implementing the posyandu program, are the main movers in promotive, preventive activities and are motivators for community members. The aim of this service is to analyse knowledge about PHBS among posyandu cadres in Tamanan Village, Tamanan District, Bondowoso Regency. The service method is an outreach activity aimed at providing knowledge about CHLB with the hope that people will change their behaviour to protect their health and the environment independently. Formative evaluation procedures in the form of pretest and posttest. Data were analyzed using descriptive analysis techniques. Continue with the normality test and paired sample t-test. The results obtained were that this community service activity was carried out on all posyandu cadres. Evaluation showed that there was a difference in the average test scores before and after the counselling. Providing counselling is able to provide changes in the knowledge of posyandu cadres which is marked by an increase in posttest scores which are higher compared to posttest scores. The conclusion is that the knowledge of Tamanan Bondowoso Village Posyandu cadres regarding CHLB in efforts to reduce stunting in toddlers can be increased through the counselling provided.Keywords: CHLB, counseling, posyandu cadres, stunting.
