Effect of Different Types of Denture Cleansers on Hardliner Surface Roughness

  Introduction: Hard liner is a denture relining material which can be used directly at the chairside in brief time. The characteristic of the hardliner is its susceptibility towards porosity which consequently resulting biofilm accumulation and Candida albicans colonization. Thus, there is a need for denture cleaning. Alkaline peroxide is a type of denture cleanser which is widely used, but it could affect the physical properties of hard liner. One of the traditional ingredients that have the potential to be used as an alternative to denture cleanser is cinnamon. Objective: This study aimed to evaluate the effect of different types of denture cleansers on the surface roughness of hard liner. Method: Twelve cylindrical hard liner specimens (15mm x 10mm, ASTM: D-2240 64T) were divided into three groups: group I (immersed in distilled water), group II (immersed in alkaline peroxide) and group III (immersed in 1.5% extract cinnamon). All specimens were soaked for 15 minutes/day for 7 days. Surface roughness was measured using surface roughness tester (Handysurf E-MC-S24B Japan). Data were analysed using one-way ANOVA and post hoc Bonferroni (α=0.05). Results: The highest average of surface roughness was shown on specimens immersed in alkaline peroxide, followed by specimens immersed in 1.5% cinnamon extract and distilled water, respectively. There were a significant difference in surface roughness values in all groups (p<0.05). Conclusion: There is an effect of type of denture cleanser on the surface hardness of hard liner

Tujuan dari penelitian ini adalah untuk mengetahui Hubungan dengan Penggunaan Metode Pembelajaran Kooperatif Pada Minat Belajar Siswa Dalam Pembelajaran Bahasa Arab di MTS Negeri 28 Jakarta. Penelitian ini dilaksanakan di MTS Negeri 28 Jakarta pada siswa kelas VIII Semester 1 Tahun Ajaran 2019 – 2020, yang dimulai pada bulan September 2019. Metode penelitian yuang digunakan dalam penelitian ini adalah metode Korelasional, penelitian yang dimaksudkan untuk mengetahui ada-tidaknya hubungan antara dua atau beberapa variabel pada suatu studi kelompok subjek. Instrument yang digunakan adalah Angket , Instrumen penelitian ini berupa sistem angket yang berisi butir-butir pernyataan dan pertanyaan untuk diberi tanggapan oleh subjek penelitian. Pengembangan instumen disusun berdasarkan atas deskripsi teoritik yang telah disusun sebelumnya, kemudian dijabarkan ke dalam butir-butir pertanyaan. Skala pengukuran instrumen menggunakan model skala bertingkat (model skala Likert) dengan empat alternatif jawaban, dengan bobot nilai 1, 2, 3, dan 4. Berdasarkan hasil penelitian ini diperoleh terdapat Hubungan dengan Penggunaan Metode Pembelajaran Kooperatif Pada Minat Belajar Siswa Dalam Pembelajaran Bahasa Arab di MTS Negeri 28 Jakarta. Hal ini ditunjukkan dari nilai r hitung sebesar 0,000, sedangkan harga r tabel sebesar 0,2782 pada taraf siginifikasi 5%. Jadi harga r hitung lebih kecil dari harga r tabel sehingga hubungannya positif dan signifikan. Hal ini berarti Model Pembelajaran Make A Match memberikan dampak positif secara signifikan terhadap Minat Belajar Siswa. Pada hasil penelitian di atas, menunjukan bahwa adanya hubungan yang positif secara signifikan antara model pembelajaran make a match dengan minat belajar siswa . Kemungkinan ini dapat terjadi karena model pembelajaran make a match yang dicapai siswa tinggi sehingga dapat menyebabkan hubungan minat belajar siswa.

This research was conducted at MTS Negeri 28 Jakarta in class VIII students in Semester 2, Academic Year 2019 - 2020, which began in June 2020. The research method used in this study is the Correlational method, research that is intended to determine whether there is a relationship between two or several variables in a subject group study. The instrument used was the Questionnaire. This research instrument was in the form of a questionnaire system that contained items of statements and questions to be given a response by the research subjects. The development of the instrument is arranged based on the theoretical description that has been compiled before, then translated into question items. The measurement scale of the instrument uses a multilevel scale model (Likert scale model) with four alternative answers, weighing 1, 2, 3, and 4. Based on the results of this study, there is a relationship between the Make a Match Type Cooperative Learning Model and Student Learning Interest in Arabic Language Learning at MTS Negeri 28 Jakarta. This is indicated by the calculated r value of 0,000, while the r table price of 0.2782 at the 5% significance level So the calculated r value is smaller than the r table price so that the relationship is positive and significant. This means that the Make A Match Learning Model has a significant positive impact on Student Learning Interests. The results of the research above indicate that there is a significant positive relationship between the make a match learning model and students' interest in learning. This possibility can occur because the make a match learning model achieved by students is high so that it can lead to a relationship between student interest in learning. So, this research can prove that there is a significant positive relationship between the Make A Match Learning Model and Student Learning Interests

PERENCANAAN PENERAPAN SISTEM DRAINASE BERWAWASAN LINGKUNGAN (EKO-DRAINASE) DI KAWASAN KEC. TALLO

Drainase perkotaan merupakan sarana atau prasarana yang ada di perkotaan yang berfungsi untuk mengalirkan air hujan dari suatu tempat ke tempat yang lain. Untuk menciptakan daerah kawasan layanan yang aman terhadap genangan air, konsep perencanaan bangunan berwawasan lingkungan perlu di perhatikan. Salah satu Kawasan yang sering terjadinya banjir yaitu di Kelurahan Ujung Pandang Baru Kecamatan Tallo Kota Makassar walaupun beberapa upaya penanganan sering dilakukan karena padatnya penduduk warga dan kurangnya daerah resapan menyebabkan drainase tidak mampu menampung air yang berlebihan pada saat musim hujan. Berdasarkan hasil analisis, kondisi saluran drainase yang ada di wilayah ini memerlukan rehabilitasi atau perbaikan yang berwawasan lingkungan, karena masih ada saluran yang tidak berfungsi untuk mengalirkan air limpah maupun limpasan air hujan. Perencanaan pengembangan sistem drainase yang berwawasan lingkungan yang direkomendasikan yaitu penerapan metode bioretensi dengan dimensi 2 m × 23,55 m × 1,5 m dengan kapasitas 0,460 m3/detik > 0,138 m3/detik (Q genangan). Sehingga metode bioretensi ini mampu menampung air limpasan yang terjadi
