ABSTRAK Masalah kesehatan gigi yang sering terjadi pada anak usia sekolah yaitu karies. Kurangnya pengetahuan mengenai kesehatan gigi menyebabkan tingginya angka karies pada anak. Anak pada usia sekolah cenderung akan mencontoh perilaku gurunya, sehingga guru dapat berperan dalam meningkatkan pengetahuan kesehatan gigi pada anak usia sekolah. Pada masa pandemi ini, terdapat keterbatasan dalam memberikan edukasi secara langsung di lingkungan sekolah. Tujuan kegiatan ini yaitu dengan pemberian edukasi kepada guru mengenai kesehatan gigi, sehingga dapat meningkatkan pengetahuan para guru dan diharapkan para guru dapat menjadi penggerak dalam meningkatkan pengetahuan mengenai kesehatan gigi pada anak usia sekolah. Metode penyuluhan dilakukan dengan pemberian materi dalam bentuk presentasi power point secara daring melalui aplikasi zoom dan penggunaan alat peraga kesehatan gigi. Hasil penyuluhan menunjukkan adanya peningkatan pengetahuan mengenai kesehatan gigi. Setelah dilakukan penyuluhan dengan metode ini, dapat disimpulkan bahwa alat peraga dianggap efektif dalam membantu keberhasilan pendidikan kesehatan gigi serta meningkatkan pemahaman dan antusias para guru TK. Kata kunci: kesehatan gigi, alat peraga, guru TK, karies gigi ABSTRACT A dental health problem that often occurs in school-age children is caries. Lack of knowledge about dental health causes high caries rates in children. Children at school age tend to imitate the behavior of their teachers so that teachers play a role in increasing knowledge of dental health in school-age children. During this pandemic, there are limitations to providing education directly in the school environment. The aim of this activity is to provide education to teachers about dental health. So that it can increase the knowledge of teachers and it is hoped that teachers can be a pioneer in increasing knowledge about dental health in school-age children. The method was carried out by providing material in the form of an online powerpoint presentation through zoom application and the use of dental health teaching aids. The result of this activity showed an increase in knowledge about dental health. After conducting counseling, it can be concluded that the use of teaching aids is effective in contributing to the success of dental health education and increasing the understanding and enthusiasm of kindergarten teachers.

ABSTRAK Kebijakan Pembatasan Sosial Berskala Besar (PSBB) yang diberlakukan di Indonesia mengharuskan masyarakat dari berbagai sektor melakukan kegiatan dari rumah, termasuk sektor pendidikan. Sektor pendidikan memberlakukan Pembelajaran Jarak Jauh (PJJ) selama pandemi COVID-19, para siswa melakukan pembelajaran secara daring menggunakan gadget. Penggunaan gadget dalam waktu lama dengan postur buruk dan postur duduk yang tidak ergonomis dapat menyebabkan gangguan pada otot terutama otot leher, bahu dan punggung. Melakukan penyuluhan dan pelatihan secara daring dan luring untuk meningkatkan pengetahuan siswa terhadap pencegahan nyeri otot selama pembelajaran jarak jauh masa pandemi COVID-19. Penyuluhan dan pelatihan dilakukan dengan kombinasi daring dan luring kepada 64 orang siswa SMP Islam Bahagia, Jakarta Barat. Penelitian deskriptif analitik secara cross-sectional dilakukan dengan menggunakan pre-test dan post-test untuk menilai tingkat pengetahuan. Terdapat peningkatan nilai rata-rata pada post-test dan hasil uji-T data berpasangan terhadap pre-test dan post-test para siswa menunjukkan ada perbedaan bermakna (p: 0,000) dengan nilai korelasi r: 0,638 (korelasi kuat). Terdapat peningkatan pengetahuan siswa terhadap pencegahan nyeri otot selama pembelajaran jarak jauh masa pandemi COVID-19 melalui metode penyuluhan dan pelatihan secara daring dan luring. Kata Kunci: Pembelajaran Jarak Jauh, Gadget, Nyeri Otot, Postur Tubuh, Peregangan Otot ABSTRACT The Large-Scale Social Restriction Policy (PSBB) implemented in Indonesia requires people from various sectors to carry out activities from home, including the education sector. The education sector applies distance learning (PJJ) during the COVID-19 pandemic. Therefore, students learn online using gadgets. The use of gadgets for a long time with poor posture and non-ergonomic sitting postures can cause muscle disorders, especially in the neck, shoulders, and back muscles. Conduct online and offline counseling and training to improve students' knowledge of preventing muscle pain during distance learning in the COVID-19 pandemic. Counseling and training were conducted using a combination of online and offline methods for 64 students at Bahagia Islamic Junior High School, West Jakarta. A cross-sectional descriptive-analytic study was conducted using a pre-test and post-test to assess the level of knowledge. Result: There was an increase in the average score on the post-test and the paired data T-test result on the students' pre-test and post-test showed that there was a significant difference (p: 0.000) with a correlation value of r: 0.638 (strong correlation). Conclusion: There was an improvement in students' knowledge of preventing muscle pain during distance learning during the COVID-19 pandemic through online and offline counseling and training methods.

Pendahuluan: Penambahan nanokitosan pada modifikasi bahan restorasi kedokteran gigi bertujuan untuk memperbaiki sifat mekanik. Sifat mekanik dari suatu bahan dipengaruhi oleh struktur permukaannya. Bahan restorasi yang banyak dilakukan modifikasi yaitu Semen Ionomer Kaca (SIK), salah satunya dengan menambahkan nanokitosan. Sumber nanokitosan dapat berasal dari eksoskeleton serangga kumbang tanduk (Xylotrupes gideon). Xylotrupes gideon memiliki kandungan kitin sebesar 47%. Penelitian ini bertujuan untuk menganalisis morfologi permukaan semen ionomer kaca dengan modifikasi penambahan nanokitosan kumang tanduk. Metode: Jenis penelitian yaitu eksperimental laboratorium. Sampel berbentuk silindris dengan ukuran 6 mm (tinggi) × 4 mm (diameter). Pengambilan sampel menggunakan teknik purposive sampling. Jumlah sampel minimal sebanyak 1 sampel untuk setiap kelompok yaitu kelompok (A) SIK konvensional (kontrol), (B) SIK modifikasi 10% vol/vol larutan nanokitosan, (C) SIK modifikasi 5% vol/vol larutan nanokitosan, (D) SIK modifikasi 10% weight/weight bubuk nanokitosan, dan (E) SIK modifikasi 5% weight/weight bubuk nanokitosan. Sampel yang telah dibuat disimpan dalam inkubator dengan suhu 37°C. Karakterisasi morfologi permukaan sampel menggunakan Scanning Electron Microscopy (SEM). Hasil: Karakterisasi SEM menunjukkan adanya variasi retakan pada permukaan sampel yang diperiksa dengan pembesaran 2000× dan 3500×. SIK modifikasi bubuk nanokitosan menunjukkan lebih banyak retakan pada permukaannya serta peningkatan rasio nanokitosan kumbang tanduk menunjukkan peningkatan keretakan pada morfologi permukaan SIK. Simpulan: Penambahan nanokitosan kumbang tanduk (Xylotrupes gideon) pada Semen Ionomer Kaca mengakibatkan perubahan morfologi permukaan SIK.Kata kunci: Semen ionomer kaca; kumbang tanduk; scanning electron microscopy ABSTRACTIntroduction: The addition of nanochitosan to the modification of dental restorative materials improves mechanical properties. Its surface structure influences the mechanical properties of a material. The restoration material that has been modified a lot is Glass Ionomer Cement (GIC), one of which is by adding nano chitosan. The source of nano chitosan can be derived from the exoskeleton of the rhinoceros beetle (Xylotrupes gideon). Rhinoceros beetle has a chitin content of 47%. This study aims to analyse the surface morphology of the glass ionomer cement with the modification of the addition of nano chitosan of rhinoceros beetle. Methods: This type of research was an experimental laboratory. The sample was cylindrical with 6 mm (height) × 4 mm (diameter). The sampling used was a purposive sampling technique. The minimum number of samples was one sample for each group, namely group (A) conventional (control) GIC, (B) modified GIC 10% vol/vol nanochitosan solution, (C) GIC modified 5% vol/vol nanochitosan solution, (D) GIC modification of 10% weight/weight of nanochitosan powder, and (E) modified GIC of 5% weight/weight of nanochitosan powder. Samples that have been made were stored in an incubator at 37°C. Characterisation of the surface morphology of the sample using Scanning Electron Microscopy (SEM). Results: SEM characterisation showed variations of cracks on the surface of the samples examined at 2000x and 3500x magnification. GIC modified nano chitosan powder showed more cracks on the surface, and an increase in the ratio of rhinoceros beetle nano chitosan showed an increase in cracks in the surface morphology of the GIC. Conclusions: The addition of nano chitosan of rhinoceros beetle to the GIC resulted in changes in the surface morphology.Keywords: Glass ionomer cement; rhinoceros beetle; scanning electron microscopy
