Abstract

Background: Calcium is a material that is mostly contained in the Anadara-granose shell. Beta-TCP can be obtained from the hydrothermal process from the Anadara-granose shell. Beta-TCP has a chemical composition that approximates the structure of bones and teeth. Objective:The microencapsulation technique aims to increase stability, reduce side effects and toxic effects of drugs, and prolong the release of ingredients. The encapsulation process is an attempt to inhibit the dissolution speed of Calcium to prevent tunnel defects. Methods: Anadara-granose shell powder was subjected to hydrothermal processing for 18 hours and sintering for 3 hours. The beta-TCP powder was dissolved with aquadest using a magnetic stirrer until it was homogeneous, Na-alginate was dissolved in aquadest until it was homogeneous with a magnetic stirrer then the two solutions were mixed and the CaCl2 solution was dropped. The sample was divided into 3 groups; Pure Beta-TCP(K-); 7 hours stirring (P1); 8 hours stirring (P2). After completion of the stirrer, the samples were centrifuged at 2500 rpm for 6 minutes, then freeze-dried for 12 hours. The level test was carried out using complexometry comparing the pure Beta-TCP group with the Beta-TCP stirrer encapsulation process for 7 hours and 8 hours. Results: The data showed that the average calcium level in K(-) group with pure Beta-TCP was 8.63%, the P1 Beta-TCP group with 7 hours stirrer 2.86%, and the P2 Beta-TCP group with 8 hours stirrer 2.12%. Conclusion: In the Anadara-granosa shell nanoencapsulation process, the calcium level gradually decreased with the longer duration of stirring time

Abstract

Background: Enterococcus faecalis is one of the bacteria which have ability to form biofilms that can cause persistent endodontic infections. Biofilm is a communities of well-organized bacteria adhere to the surface and coated by layer of extracellular polysaccharide matrix. The extracts of mangrove Acanthus ilicifolius leaves have been known to have potentially bioactive compounds as antibacterial such as saponins, alkaloids, terpenoids, and tannins. Purpose: The aim of this study was to determine the antibacterial effectiveness of mangrove Acanthus ilicifolius leaves extracts to Enterococcus faecalis biofilm. Materials and Methods: This study was true experimental laboratory with post test only control group design. The sample in this study was Enterococcus faecalis, divided into 6 groups consisted of control positive (NaOCl 2.5%) group, and 5 treatment groups of mangrove Acanthus ilicifolius leaves extract with different concentration of 60 mg/ml; 70 mg/ml; 80 mg/ml; 90 mg/ml; and 100mg/ml and be repeated 8 times. Enterococcus faecalis bacteria were cultured in mediaTSBglu incubated for 24 hours. Amount of 0.1 ml of bacteria Enterococcus faecalis with concentrations of 106were loaded on microtiter plate then stained with crystal violet. Biofilms checked by measuring optical density (OD) using an ELISA reader. Data were analyzed by One-way ANOVA followed by Post Hoc test. Result: Acanthus ilicifolius leaves extract decrease the OD of Enterococcus faecalis biofilm (p<0,05) in all groups. Conclusion: The extract of mangrove Acanthus ilicifolius leaves extract have antibacterial efficacy against Enterococcus faecalis biofilm.

Abstract

This study aims to analyze the problem of using proper and correct Indonesian on social media in an effort to preserve the national language. The method used is a qualitative descriptive approach with observation and documentation techniques of posts on Facebook, Instagram, and TikTok. The results show that language use on social media is still dominated by non-standard forms, abbreviations, and the mixing of foreign languages ​​that do not comply with linguistic rules. This phenomenon is influenced by factors of communication practicality, digital culture, and low language awareness. Consequently, formal Indonesian language skills have the potential to decline if not addressed immediately. Therefore, efforts are needed to increase linguistic literacy and public awareness in using proper and correct Indonesian in the digital space as part of preserving national identity.

Abstract

Dental and oral problems in Indonesian children are caused by low knowledge, comprehension, and behavior that ignores dental and oral health maintenance, resulting in tooth and mouth damage. This activity is in partnership with SD Yapita which is a school supported by the Faculty of Dentistry, Hang Tuah University. The aim is to prepare parents and teachers of Yapita Elementary School students to become ambassadors for oral and dental hygiene so that they can become mentors for their children or students. This method is carried out online and offline from classes 1 to 6 using a simple random sampling technique. The results were statistically analyzed using the Paired T-test. The average pre-test score from the teacher was 60 and the parents were 56, while the post-test result from the teacher was 84 and the parents was 85. The results of the data analysis were normally distributed (p>0.05) followed by the Paired correlation test T-test. The results show a relationship between the pre and post-test of teachers and parents. This shows that this educational activity can increase the knowledge of teachers and parents so that they can become ambassadors of oral and dental hygiene to their children or students.

Abstract

Penelitian ini bertujuan untuk mengembangkan media pembelajaran interaktif berbasis platform Educandy guna meningkatkan hasil belajar siswa kelas VIII SMPN 3 Monta pada materi software dalam mata pelajaran Informatika. Penelitian ini dilatarbelakangi oleh rendahnya hasil belajar siswa, kurangnya keterlibatan siswa dalam proses pembelajaran, serta belum optimalnya pemanfaatan media pembelajaran berbasis teknologi yang mendukung pembelajaran aktif dan berpusat pada siswa. Penelitian menggunakan metode Research and Development (R&D) dengan model pengembangan ADDIE yang meliputi tahap Analysis, Design, Development, Implementation, dan Evaluation. Produk yang dikembangkan berupa media pembelajaran interaktif berbasis Educandy yang mengintegrasikan aktivitas game-based learning, seperti kuis, matching pairs, word search, dan anagram untuk membantu siswa memahami materi software. Subjek penelitian terdiri atas 19 siswa kelas VIII SMPN 3 Monta. Kelayakan media dinilai melalui validasi oleh ahli media dan ahli materi, sedangkan efektivitasnya diukur menggunakan tes hasil belajar melalui pretest dan posttest. Hasil penelitian menunjukkan bahwa media memperoleh nilai validasi sebesar 90% dari ahli media dan 83,34% dari ahli materi dengan kategori sangat layak. Nilai rata-rata hasil belajar siswa meningkat dari 55,00 pada pretest menjadi 89,42 pada posttest. Hasil analisis N-Gain sebesar 0,81 termasuk kategori tinggi, yang menunjukkan bahwa media pembelajaran berbasis Educandy efektif dalam meningkatkan hasil belajar siswa. Dengan demikian, media pembelajaran interaktif berbasis Educandy layak digunakan sebagai alternatif pembelajaran digital yang inovatif untuk meningkatkan kualitas pembelajaran Informatika di tingkat SMP.
